Everything about nuclear energy seems terrifically big: the cost, construction and decommissioning—and the fears of something going badly wrong.

The future, however may well be much smaller. Dozens of companies are working on a new generation of reactors that, they promise, can deliver nuclear power at lower cost and reduced risk.

These small-scale plants will on average generate between 50MW and 300MW of power compared with the 1,000MW-plus from a conventional reactor. They will draw on modular manufacturing techniques that will reduce construction risk, which has plagued larger-scale projects. Supporters believe these advanced modular reactors (AMRs)—most of which will not be commercial until the 2030s—are critical if atomic power is to compete against the rapidly falling costs of solar and wind.

“The physics hasn’t changed. It’s about much cleverer design that offers much-needed flexibility in terms of operation,” said Tim Stone, long-term industry adviser and chairman of Nuclear risk Insurers, which insures nuclear sites in the UK.

Since the Fukushima meltdown in Japan in 2011, safety fears have threatened nuclear power. But the biggest obstacle today is economic. In western Europe, just three plants are under construction: in the UK at Hinkley point in Somerset; at Flamanville in France; and at Olkiluoto in Finland. All involve the European Pressurized Reactor technology of EDF that will be used at Hinkley Point. All are running years late and over budget. In the US, the first two nuclear projects under way for the past 30 years are also blowing through cost estimates.

The UK, which opened the world’s first commercial nuclear reactor in 1956, is one of the few western nations committed to renewing its ageing fleet to ensure energy security and meet tough carbon reduction targets. It is seen as a proving ground, by many in the industry, of nuclear power’s ability to restore confidence.

However, the country’s agreement with EDF to build two units at Hinkley Point—which together will generate 3.2GW of electricity—has come under severe criticism over its cost. The government is looking at different funding models but said it still sees nuclear power as vital to the country’s future energy mix. Small reactors, it believes, have the potential to generate much-needed power from the 2030s.

A nuclear sector deal, unveiled last month, promised up to ￡56m in funding for research and development into AMRs and attracted interest of start-ups from around the world. The government hopes the funding will give the UK a lead in the global race to develop these technologies, helping to provide energy security while also creating a multibillion-dollar export market for British engineering companies.

1.Which of the following is true about the advanced modular reactors (AMRs)?

A. AMRs produce more power than traditional reactors.

B. So far, most AMRs have not been put into use yet.

C. Small in scale, AMRs rose more safety risks.

D. Governments prefer energy of solar and wind to that of AMRs.

2.In paragraph 5, the author mentions the plants in Western Europe and the US to ________..

A. prove that nuclear power has been threatened by safety concern.

B. indicate the construction of nuclear plants are slow in speed.

C. show that the construction of nuclear power plants cost more than the budget available.

D. point out that most power plants have adopted the latest nuclear technology.

3.What can be inferred from the passage?

A. A kind costs for small modular reactors would be higher relative to large nuclear reactors.

B. The UK government seeks to reduce the negative impact of nuclear power on its economy.

C. The plan to build two power plants in Hinkley Point has been deserted.

D. Some people have lost confidence in the development of nuclear plants.

4.Which of the following can serve as the best title of this passage?

A. Britain counts on nuclear energy to keep lights on

B. Traditional nuclear plants boom with mini reactors

C. Nuclear power looks to shrink its way to success

D. Nuclear’s share of power generation remain stead

As smog forced students to stay home, the online learning industry saw a sharp increase in consumers.

During the air pollution red alert from Dec. 8 to 10 last winter, the Beijing Commission of Education ordered all kindergartens, primary schools and middle schools to suspend classes (停课). But the commission urged that, "Teachers should guide students to make full use of digital materials and conduct online learning at home".

A Few Active Listening Guidelines

Listening is arguably the most important element of interpersonal communication. Our ability to listen well impacts the quality of all of our relationships, and not just at home with our family and friends—it can also affect our relationships and interactions on the job, as well as the effectiveness and quality of our work.

1. Instead, it is a skill that must be cultivated and practiced. Active listening means the difference between simply hearing, and listening with the intent to truly understand. It is a subtle but important distinction.

1. Give focused attention.

Try to minimize external (外部的) distractions. Turn down the noise, and put down or step away from what you’re doing if possible. 2. Don’t watch the clock, fidget (坐立不安) or go over your to-do list for later.

2. 3.

Direct eye contact shows your attention and intention to listen. This doesn’t mean stare, though. Be reasonable, but try not to let your eyes wander to whatever is going on around you.

3. Reflect back.

Restate, but don’t repeat word for word. Paraphrase what you think the other part is saying with responses such as: “What I’m hearing is…” or “Let me see if I’m following you... ”4.

4. Respond appropriately.

Be open and honest in your responses. Share your thoughts, insights and feelings in a clear, but respectful and considerate manner even if you disagree.

Active listening is a model for good communication. 5. It takes practice to develop active listening skills, and it’s a habit that has to be reinforced（加强）. Remind yourself that the goal of conversation is not merely to trade words, but to truly understand what the other party is saying and to be understood in turn.

A. Maintain eye contact.

B. Instead, focus on what is being said.

C. You do not have to agree on everything.

D. Also, set aside other internal thinking and dialogue.

E. Listening is not something that comes naturally or easily for most of us.

F. Reflecting what you’ve heard signals that you’re attempting to understand fully.

G. Remember that listening is not just to gather information and share ideas, but also to gain perspective and understanding.

On the banks of Tanzania’s Lake Eyasi lives the world’s last hunter-gatherer tribe (部落) — the Hadza. They don’t grow food, raise animals or build houses. Instead they live a life unchanged for more than ten thousand years.

Their world is one of complete freedom — something modern society can barely imagine and is unlikely to ever experience, let alone have the skills to stay alive. Text messages and phone calls don’t exist. Nor do cars and electricity. No jobs, timetables, and social structures. No laws, taxes and unbelievably, no money — the closest thing to currency (交易) is the trade for a pair of shorts with a neighboring tribe.

We spent our time with the Hadza hunting baboons (狒狒), a daily activity for the men. Their land is packed with sharp bushes, poisonous snakes and man-eating lions. But a successful hunting trip is the difference between eating or going hungry.

The Hadza diet consists mainly of honey, fruit and meat. Men often hunt in pairs to shoot animals with bows and arrows. The Hadza show us how to track animals, from baboons to snakes to lions. They are hugely skilled with their handmade bows and arrows — we have a go and barely get the arrow to go three feet in front of us.

The language of the Hadza is believed to be the oldest still-spoken language known to man. The Hadza don’t have conflict, and have no memory of starvation. Their population never reaches numbers that cannot be supported through hunting or gathering. They never get from their land more than they need.

Unlike modern-day office workers, the Hadza enjoy an extraordinary amount of free time. Their “work” — hunting for food — takes up around five hours of their day. They’ve been in such a state of peaceful existence for thousands of years.

1.We can learn from the text that the Hadza_______.

A. lead a very simple life

B. live on traditional agriculture

C. have their own system of currency

D. show a lot of interest in new technology

2.Which of the following can describe the Hadza’s environment?

A. Stressful.

B. Comfortable.

C. Exciting.

D. Dangerous.

3.The relationship between the Hadza and nature_______.

A. is going wrong

B. is full of conflict

C. is in perfect harmony

D. is changing all the time

4.Why does the author come to visit the Hadza?

A. To study their native language.

B. To get to know their way of life.

C. To learn survival skills from them.

D. To persuade them to protect animals.

A walk through the galleries of Quebec's Montreal Museum of Fine Arts (MMFA) places individuals face-to-face with some 43,000 artworks ranging from Chinese ceramics (陶瓷制品) to Inuit sculpture.

While the visiting is an incredible cultural experience, a group of local physicians will soon be able to prescribe(开处方) museum visits as treatment for some illnesses.

"We know that art contributes to neural(神经的) activity," said MMFA director Nathalie Bondil. "What we see is that being in contact with art can really help your well-being."

Hélène Boyer, vice president of a Montreal-based medical association, explains that museum visits have been shown to increase levels of serotonin, a neurotransmitter (神经传导物质) known as the "happy chemical" which helps to lift mood.

According to Boyer, the small increase in hormones（荷尔蒙）associated with enjoying an afternoon of art is similar to that offered by exercise, making museum prescriptions ideal for the elderly experiencing pain that prevents them from regularly joining in physical activity.

The museum visits are designed to improve traditional methods. As Bondil notes, spending time in a peaceful environment can provide a welcome distraction. "What is most important is this experience can help them escape from their own pain," she says. "When you enter the museum, you escape from the speed of our daily life."

"I am convinced that in the 21st century, culture will be what physical activity was for health in the 20th century," said Bondil. "Some people would do well to recall that just in the 19th century, sports were believed to do harm to the body. Just as doctors now prescribe exercise, they will be able to prescribe a visit to the MMFA."

1.What does Hélène Boyer think of museum visits?

A. They can cheer people up.

B. They can reduce physical activity.

C. They can slow down our life pace.

D. They can increase levels of art appreciation.

2.How do museum visits affect people?

A. Stop them concentrating on pain.

B. Stop them focusing on traditional methods.

C. Encourage them not to be absent-minded.

D. Encourage them to slow their steps while walking.

3.What does the last paragraph suggest?

A. Physical activities were popular in the 19th century.

B. Sports are considered to be harmful to the body.

C. Ideas of treating illnesses are changing over time.

D. Doctors prescribe museum visits regularly now.

4.What is the main idea of the text?

A. Museum visits are ideal for the elderly.

B. Happy chemical helps to lift mood.

C. Peaceful environment helps escape pain.

D. Cultural activities will promote health.

Paris is the city of dreams. If you plan to head to Paris for a study period, then perhaps a little reality check is in order. But my experience was a romantic one.

I paved my path to Paris through an exchange program. On arrival in Paris, I was constantly reminded of the official processes I had to complete — forms to be filled in, meetings to attend, the list seemed endless.

Then the real work began. Once classes were underway, I found myself volunteering to do oral presentations and assignments first, rather than last. This method proved to be very helpful.

Once I had finished class for the week, I had an ever-increasing list of museums to visit, neighborhoods to explore, and cafés to sit in. Read books about Paris. Talk to locals and other foreigners living there. But the one thing that reading a book or talking to someone cannot do is to provide you with the experience of wandering Paris on foot. The people watching, the sounds of the city, the colors as the seasons change, they all add to the ecstasy that I experience in Paris as an exchange student.

After spending five months wandering through the charming neighborhoods, I fell in love with the atmosphere that came out from every open door, and with every spoken word. There is something comforting about walking to the market each Sunday to enjoy the beautiful display of fruits, vegetables and dairy products. There is warmth in saying bonjour to the passers-by.

On my last day in Paris, I confidently said, “Bonjour Monsieur,” as I passed the little store down the street. I guess the best part about going on exchange in Paris is falling in love with the city in your own way. And I know mine is unique and special to me, my own little pieces of Paris.

1.What does the underlined word "ecstasy" in Paragraph 4 probably mean?

A. Courage. B. Imagination.

C. Happiness. D. Reputation.

2.What does the passage mainly tell us?

A. An exchange student’s life. B. Charming neighborhoods.

C. An exchange program. D. A traveling experience.

3.Beyond reading books, which experience would the author treasure most?

A. Enjoying coffee in his spare time.

B. Greeting people in French in the street.

C. Buying vegetables in the market.

D. Hanging around in Paris.

4.According to the passage, what left the author the deepest impression?

A. The friendly people he met in Paris.

B. The special culture he experienced in the city.

C. The academic achievement he made in his study.

D. The presentations and assignments he did in class.

Unbelievable Stories of Animals Acting Just Like Humans

◆Horses are picky eaters

Horses have an even better sense of smell than humans do. When horses raise their noses and open their nostrils (鼻孔) , their nervous system allows them to sense smells we can’t sense. This might explain why they refuse dirty water and carefully move around meadows, eating only the tastiest grasses, experts say.

◆Whale says thanks

In 2011, a whale expert spotted a humpback whale trapped in a fishing net and spent an hour freeing it. Afterward, in an hour-long display of thanks, the whale swam near their boat and leaped into the air about 40 times.

◆Pandas like to be naughty

Is there anything more lovely than a baby panda, except maybe a human baby? In fact, baby pandas sometimes behave like human babies. They sleep in the same positions and value their thumbs. Pandas are shy by nature for its shy behaviors such as covering its face with a paw of ducking its head when confronted by a stranger.

◆A cat honors its owner

Paper towels, and a plastic cup are just a few of the gifts that Toldo, a devoted three-year-old gray-and-white cat, has placed on his former owner Iozzelli Renzo’s grave every day since the man died in September 2011. Renzo adopted Toldo from a shelter when the cat was three months old, and the two formed an inseparable bond. After Renzo passed away, Toldo followed the coffin to the cemetery, and now "stands guard" at the grave for hours at a time.

According to a recent study, a new genetically modified rice can prevent infections of HIV, the virus responsible for the disease AIDS.

The study reports the newly-developed rice produces proteins that attach directly to the HIV virus. This process prevents the virus from mixing with human cells. The scientists say it can remove the effect of the virus and block its spreading.

The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly two-thirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease.

The new study predicts the rice-based method will lead to long-term use of the anti-HIV treatment across the developing world. Researchers said the “groundbreaking” discovery is “realistically the only way” that anti-HIV combination treatments can be produced at a cost low enough for the developing world.

They say the easiest and most cost-effective way to use the rice will be to make it into a cream to be put on the skin. The HIV-fighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine.

The process of changing the genetic structure of food crops has been debated for some time. Critics of genetically engineered crops believe they can harm people. The scientific team says further testing is needed to ensure that the genetic engineering process does not produce any additional chemicals that could be dangerous to people.

1.What does the author intend to do in paragraph 3?

2.In which way will the rice be used at the lowest cost?

A. By transforming it into proteins. B. By adding it to an oral drug.

C. By attaching it to the HIV virus. D. By processing it into a cream.

3.What can we infer about the genetic engineering process?

A. It can prevent infections of HIV. B. It can produce dangerous chemicals.

While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world’s first kids to be “taught” by a digital teacher. Before you start imagining a human-like robot walking around the classroom, Will is just an avatar that appears on the student’s desktop, or smartphone screen, when ordered to come.

The autonomous animation platform has been modeled after the human brain and nervous system, allowing it to show human-like behavior. The digital teacher is assigned to teach Vector’s “Be sustainable with energy”— a free program for Auckland elementary schools.

Just like the humans it replaced, Will is able to instantly react to the students’ responses to the topic. Thanks to a webcam and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues. For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps attract the students’ attention, but also allows the program’s developers to monitor their engagement, and make changes if needed.

Nikhil Ravishankar believes that Will-like avatars could be a novel way to catch the attention of the next generation. He says, “I have a lot of hope in this technology as a means to deliver cost-effective, rich, educational experience in the future.”

The program, in place since August 2018, has been a great success thus far. Ravishankar says, “ What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention.” However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon.

1.What was special for some elementary school students in Auckland?

A. A digital teacher taught them.

B. They first saw something digital.

C. This was the start of a new school year.

D. They could get close to smartphone screen.

2.What is the benefit of this two-way interaction?

A. It can smile back. B. It can use microphone.

C. It can talk any topic for free. D. It can change if necessary.

3.What’s Ravishankar’s attitude to Will’s replacing Human educators soon?

A. Optimistic. B. Doubtful.

C. Unclear. D. Disapproving.

4.What might be the best title for the passage?

A. New High-tech Contributes to Education

B. The World’s First Digital Teacher Appears in Classroom.

C. The World’s First Digital Teacher, a Help to Students

D. New Zealand Will Replace Teachers in Classrooms

For most of her life, Suanne Laqueur’s passion for storytelling was shown on the dance floor.

Although Laqueur began writing at a young age, dancing always took center stage. She majored in dance and theater at Alfred University and taught at her mother’s dance studio in Croton-on-Hudson, New York, for years. But when her mother was ready to retire and an opportunity opened for Laqueur to take over the studio, she realized she had no interest in taking on the business side of her art: “Owning a studio is a lot of work—financially, logistically. I love the teaching, the choreographing(编舞), the staging, but I didn’t want to own it.”

Yet Laqueur’s disinterest in running the studio changed when she became a self-published author. In the fall of 2013, she decided to pursue Self-publishing as a way of sharing her first completed novel with friends and family. During the process, she realized that following her true passion—telling stories through writing—made the business of the art worthwhile, and owning that business meant she could direct her writing career however she chose.

Starting with her second self-published novel, she began investing more time in marketing and building her audience. Her investment paid off. Since 2014, Laqueur, now 49, has self-published six novels, which collectively have hundreds of ratings and reviews on Goodreads. Her 2016 novel An Exaltation of Larks stole the show at the 25th Annual Writer’s Digest Self-Published Book Awards, topping more than 2,300 entries to win the grand prize.

“You have to write the most truthful story to you, and I think self-publishing allows that freedom,’ she says. “If you work with traditional publishing, it’s more about what’s marketable, There are trade-offs, which everyone will tell you, but by self-publishing I have control of the book, I have control of the story, and I’m cool with that.”

1.From Paragraph 2，we can learn that Laqueur _______.

A. was a part-time writer when she was young

B. didn’t like teaching dancing in fact

C. wanted to own a publishing house

D. was interested in running her mother’s studio

2.What made Laqueur change her attitude to business?

A. Her mother’s persuasion. B. The desire to make money

C. Self-publishing her novels. D. Her own passion toward art.

3.Which of the following can best replace the phrase “stole the show” in Paragraph 4?

A. became a failure. B. was shown to people.

C. got all the attention. D. was accidentally stolen.

4.What can be inferred from what Laqueur’s said?

A. Self-publishing will replace traditional publishing.

B. She will never use traditional publishing.

C. Traditional publishing only focuses on the market.

D. She enjoys the way of self-publishing.

Resorts of every kind have sprung up to cater to the Englishman need to spend a part of the year, however briefly, by the seaside. No town in Britain is more than eighty miles from the sea and there are seaside resorts all round the coast. On a summer Sunday most of the roads that lead to the sea axe congested (拥挤) with cars full of people eager to get a breath of sea air. In the evening when everyone is full of food, ice-cream and lollypops, there is the long slow drive home on roads crowded with returning cars.

Brighton

Brighton is one of the best-known south coast resorts and is very popular for day trip excursions. It is only fifty miles from London and can be reached by fast train in an hour. At the weekend the pebbled beaches are thronged with people sunbathing or picking their way to the water’s edge for a dip.

Bournemouth

Located a hundred miles from London, the beaches are wide and sandy. White houses line the cliff tops and narrow valleys, densely wooded with pine trees, reach down to the shore. The area near to the town of Torquay on the Devon coast is sometimes called Britains Riviera and the climate is so mild that palm trees grow along the sea front.

Blackpool

On the north-west coast, a popular resort for the people in the industrial north, Blackpool is a gay, noisy town, famous for its amusement facilities and the magical lights. At night people travel from miles around to see the extravaganza of lights decorating the sea front.

Southend

On the east coast at the mouth of the Thames, Southend is, like Brighton, one of the favorite resorts of Londoners. The pier here is the longest in Britain and offers a great variety of differing entertainments.

1.Why do people often have a long slow drive home on roads in summer?

A. Because it is extremely far from the sea.

B. Because too many returning cars often make a traffic jam.

Directions: Read the following passage. Summarize the main idea and the main point(s)of the passage in no more than 60 words, Use your own words as far as possible.

Peter woke up one morning with all the usual signs of a nasty cold: severe headache and blocked nose. Then he did what almost everyone does on a day like this. He got up and went to work. Such is the state of what the human resources industry has come to call presenteeism.

Many experts claim that presenteeism is now a bigger problem in the UK than absenteeism and could even help explain the country’s weak productivity growth. A growing number of companies are realizing presenteeism and doing something about it. This generally takes the form of programmes full of once unimaginable sweets: cheap gym membership, veggie salads in the canteen, stand-up desks and the odd massage. of course, there’s nothing against lunchtime dentistry or free workout. They do more good than harm. But such welfares alone won't do much to stop people from presenteeism.

The chief reasons why people soldier on have nothing to do with how fit they are. They work for leaner, more stressed companies where dismissals are common. This makes some people worried that they will be targeted in the next round of job cut if they have taken a lot of time off. Others worry about troubling stretched colleagues with more work in their absence. How annoying it is to be faced with cold faces when you return to office after two days' rest at home.

There is not much to be said for "silly things" like ping-pong tables and office bean bags. The key to dealing with presenteeism lies in training managers to be better at spotting swifly when employees are under too much stress or ill, and dealing with the situation sensibly---putting the sick employee to sick leave although he is reluctant. Of course, work has to be done to eliminate employee's concern about his job prospect thereof.

Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.

Recently, in the quest for a selfie(自拍), a woman climbed over the concrete barrier of a Jaguar(美洲虎) enclosure at Wildlife World Zoo, Arizona. The jaguar ripped into her arm. Bystanders pulled her away before the animal could injure her further. She's fine-so is the jaguar.

This isn’t the first time a story of a person acting rudely to get close to a wild animal made headlines. Last year. a man jumped into a lion enclosure at a zoo for a close-up photo. 1.Multiple tourists in Yellowstone National Park have been attacked by bison(野牛) when they’ve gotten too close for a photo.

It's common sense not to get close to wild animals that can hurt you. It's why zoos have barriers -sometimes multiple walls-to keep people separated from animals. Signs posted everywhere state the obvious warning. Keep your hands off the cage.

"Yet animals have become less real to us, " says an environmentalist. We see exotic animals most frequently in managed settings like zoos. 2. People are trying to take advantage of their rarity to show off on social media and ignore their fierceness.

Media often normalize interaction with dangerous animals. Seeing a man like "Lion Whisperer" Kevin Richardson regularly play-fight with lions on TV, may send the message that these animals aren't so dangerous after all.

Social media are also perfectly positioned to contribute to the rise of animal selfies. Getting likes and comments provide instant satisfaction. Your self-esteem actually gets a temporary boost. To hold onto that feeling, people may go to more and more extremes to showcase the most exciting versions of themselves. It may not be enough to get a photo of a beautiful, dangerous animal from outside a cage. 3.

People' s careless approach can put the animal's safety at risk as well. Zoo animals often must be killed to protect the person who’s entered their space. In fact, thrill-seekers actively endanger the lives of animals. 4.with the zoo environment, they take it for granted that animals are there for people, ignoring the fact that animals and humans are both equal existents in the nature.

A. The animals, to some extent, become tools to us.

B. Although violence against zoo animals is often reported, the issue of animal welfare has aroused little attention recently.

C By taking a selfie, you show that you're part of that experience.

D. The comparison between caged animals and wild ones are appealing to people.

E. Similar incidents are a regular occurrence in natural settings.

F. The common factor is that some people are not respecting animal.

ARCHAEOLOGISTS(考古学家) GUIDED BY laser images of a remote region of northern Guatemala have discovered 20-foot-high walls, watchtowers, and other evidence that ancient Maya societies had been annoyed by warfare threat over many years. The finds have upended long-established impressions of a civilization that it tamed the jungle and built thriving cities,then declined and disappeared quietly beneath the dense tropical forest.

Among the most surprising discoveries was a large stone complex now called La Cuemavilla. Built on a steep ridge, the heavily fortified site included high walls. Moats which serves as the largest defensive system ever discovered in the region.

This was surprising says an archaeologist, "because we had a tendency to romanticize Maya warfare as something that was largely ritualized. But the fortifications were seeing suggest an elevated level of antagonism over centuries. Rulers were so deeply alarmed that they felt the need to invest in all these hilltop fortifications. There is an almost visible sense of fear in this landscape.

All these findings owe credit to PACUNAM LIDAR Initiative, a laser survey of some 800 square miles of the Maya Biosphere Reserve in northern Guatemala. Using revolutionary Laser technology, the survey revealed the long-hidden ruins of a sprawling pre-Columbian civilization that was far more complex and interconnected than most Maya specialists had supposed.

Guided by the new Laser treasure maps, the LIDAR team deployed through the jungle over the past year to conduct hands-on investigations of more than a dozen of the most promising sites-most of which would have been imperceptible without LIDAR.

"You could walk over the top of a major ruin and miss it, "says an archaeologist who's part of the PACUNA project. But LIDAR picks up the patterns and makes the features pop out with surprising clarity.

Three-dimensional maps generated by the survey yielded surprises even at Tikal, the largest and most extensively explored archaeological site in Guatemala. The ancient city was at least four times bigger than previously thought, and surrounded by a massive ditch and fortified base stretching for miles.

Archaeologists stress that LIDAR, for all its utility, will never see below the ground or yield direct dates of occupation. “we still need to dig and hack our way through the jungle, but now we have a very accurate map to guide us.

1.How did people think of Maya before the discovery of the defense ruins?

A. It was the most advanced civilization in the history of mankind.

B. It was long under the threat of large-scale wars

C. Its rise and decline were under way peacefully

D. It was finally destroyed by a large-scale war

2.The underlined word antagonism is closest in meaning to ____.

A. misery

B. revolution

C. population decrease

D. opposition

3.Which of the following statements is TRUE according to the passage?

A. The military mechanism found in La Cuemavilla was intended for occupying more lands.

B. The new laser technology was mainly used to enlarge the original site size.

C. The LIDAR helps to avoid the traditional digging task in site exploration.

D. The Tikal site was found to be protected by certain defense works

4.The passage is mainly about ____.

A. people' s long-time misunderstanding of Maya civilization.

B. discovery of Maya military works aided by new explore technology

C. the finding of a big warfare resulting in the disappearance of Maya civilization

D. The various advantages of new technologies in the field of archaeology.

While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink(臭气)too.

Vulture(秃鸳)

Vultures, are street sweepers that feast on the rotting flesh of dead animals, which benefits us by ridding our highways and landscapes of animal bodies and the bacteria they might carry. When vultures feel threatened they vomit, and the smell of vomited-on dead bodies puts of most predators. Throwing up allows the vulture to fly away more quickly-and the vomit can hurt the aggressor's eyes and face.

Opossum(负鼠)

In some ways opossums have it easy. In order to become “dead", they don’t have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere. Even if they keep getting attacked, they won't move any more than a human statue until the threat has passed.

Hoatzin(磨雉)

Hold your nose and meet the hoatzin, a bird of distinctions, not the least of which is that it smells like fresh cow shit. The animal mostly eats leaves and it's the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the “stink bird

Millipedes (千足虫)

Millipedes are tricky. For starters they look wormy. Their name is deceptive, too: Their legs number about 750. Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.

Sea Hare(海兔)

The graceful sea hare is plain in taste in the first place, so it's not the most popular dish in the seafood chain. Nonetheless this type of sea creature has a pretty creative smell-related defense that is almost the opposite of its smelly companions on this list. The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.

Researchers using lobsters(2-f)as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don't know how appealing it is.

1.The sea hare defends itself from predators by ____.

A. becoming plain in taste at the discovery of a predator

B. giving out purple ink to make itself invisible to predators

C. releasing substance to make predators unable to smell it

D. giving off smelly gas to try to drive predators away.

2.Which of the following statements is TRUE according to the passage?

A. The vulture carries bacteria so that predators dare not get close to it.

B. The opossum fakes its death to avoid being targeted by predators.

C. The hoatzin eats cow shit so that it is nick-named as “stink bird

D. The gas released by millipede was basically harmless

3.The species that enjoys more than one defense mechanism is

A. vulture

B. opossum

C. millipede

D. sea hare

After some blood tests, Dr Stubs stood before me, a tall man, but short on personality and sporting a cold expression. You have systemic lupus. he said matter-of-factly."Lupus, "he continued, "is an auto-immune disease and ….” I remember certain details but mostly I remember him talking about children. “Children are no harm. But childbirth would jumpstart additional symptoms that could be life threatening. You already have two kids anyway.”

As I got up to leave, shaken and drained, he said his parting words, “I would discourage any further research. There is no cure and nothing can prevent its progression.”

Still, I did research lupus and its symptoms tiredness and joint pain-were both consistent with what I was experiencing. And eventually some major organs could be affected, causing shutdown and possibly death.

I studied and found out that echinacea had a record in making immune system stronger. I decided that along with the plant I would strengthen my mindset by immersing myself in my family with my one-year-old son and three-year-old daughter.

After another visit, I decided never to go back to Dr. Stubs. How could one endure repeatedly hear desperately words coming from an emotionless mouth even though they were truth? The years passed. When I would feel tired and achy I pulled support from my children and their laughter.

Finally, after eight years, I went to Dr. Kirstein who was recommended by a friend. She stood there holding my hand and looking into my eyes warmly

"So, let’s talk a little

Instantly my defenses were down. Before I knew it, she had me running on and on about my children, my husband, my life and dreams. I told her about all the meaningful activities I was involved in, those things I might have never done without the disease.

After several follow-up tests, and greater research into my family history, Dr. Kirsteincame to conclusive answer. I did not have systemic lupus. There must be something wrong with the initial tests 8 years before.

I didn't know whether I should jump for joy or scream because I had been living the last eight years in fear of a fatal disease. But then I realized that I had been living every day, not so much in fear, but happiness Even day was a gift and I knew it.

A. She calmly waited for major organs to shut down.

B. she took effective medicine regularly to fight the disease.

C. She turned to Dr. Kirstein to get cure for the disease

For several decades, various types of artificial intelligence kept shocking the world. Robots could 1. people in highly competitive games and then quickly destroyed their human competitors.

AI long ago mastered chess, the Chinese board game Go and even the Rubik's cube, which it managed to solve in just 0.38 second.

Now machines have a new game that will allow them to 2. humans: Jenga, the popular game in which players 3.remove pieces from an increasingly unstable tower of 54 blocks, placing each one on top until the entire structure would 4..

A newly released video from MIT shows a robot developed by the school's engineers playing the game with surprising accuracy. The machine is equipped with a soft gripper(夹子), a force-sensing wrist and an external camera, allowing the robot to detect the tower’s 5. the way a human might do

It must 6. interactive physical operation, where you have to touch the tower to learn how and when to move blocks.

Imitating it is rather difficult, so the robot has to learn in the real world, by working with the real Jenga tower. Recently, a relevant research was published in the journal Science Robotics. Researchers say the robot demonstrates that machines can learn how to perform certain tasks through actual touching instead of relying heavily on visual 7..

To become an accomplished Jenga player, the robot did not require as much repetitive practice as you might imagine. Hoping to avoid reconstructing a Jenga tower thousands of times, researchers developed a method that allowed the robot to be trained on about 300 games. Researchers say the robot has already begun facing off against humans, who remain 10. players—for now.
