Strange ice rings in Siberia’s Lake Baikal have puzzled scientists for decades, but now the mystery apparently has been solved. The answer: the rings are caused by warm, circular currents of water under the ice, called eddies (漩涡).

The eddies’ strong currents melt the ice at the edge, but weaker ones keep the center frozen. “Results of our field surveys show that there are warm eddies that circulate in a clockwise (顺时针的) direction under the ice cover,” said Alexei Kouraev, a hydrologist at the University of Toulouse, in a NASA statement. “In the eddy center, the ice does not melt — even though the water is warm — because the currents are weak,” he said. “But on the eddy boundary, the currents are stronger, and warmer water leads to rapid melting.”

During field work, Kouraev and his colleagues drilled holes near ice rings and set sensors capable of measuring the temperature and salinity (盐浓度) of the water to a depth of 700 feet. They found that the water in the eddies was 2 to 4 ℉ warmer than the surrounding water.

Most of the rings appear in March or April and have a width of about 3 to 4 miles — too big to recognize from the ground but easily seen from satellites above. Some rings were ephemeral while others lasted for weeks or even months.

Lake Baikal is the world’s largest and deepest freshwater lake, according to Gizmodo. It’s home to many varieties of fish not seen anywhere else in the world, and even a population of freshwater seals.

Researchers are still investigating what causes Baikal’s eddies but think it’s likely because of wind patterns, rivers that flow into the lake and the shape of the lake’s coastline and bottom.

1.Which word can best replace the underlined word “ephemeral” in paragraph 4?

A.Steady. B.Current.

C.Fundamental. D.Temporary.

2.Why is the ice in the center of ice rings frozen while that at the edge is melted?

A.Because the center of ice rings is 2 to 4℉ warmer than the edge.

B.Because the currents in the center are less powerful.

C.Because it is too wide to be recognized or melted.

D.Because water in the center circulates in a clockwise direction.

3.Which of the following statements about Lake Baikal’s eddies is TRUE?

A.They are caused by hot and circular currents under the ice.

B.The ice in the center of Lake Baikal’s eddies melts faster than that of the edge.

C.Researchers are uncertain about the exact reason of the eddies’ existence.

D.Lake Beikal’s eddies can only be measured at the depth of 700 feet.

4.What maybe the best title for the passage?

A.What’s causing the giant ice rings in Siberia?

B.The mystery of the eddies' in the Lake Baikal uncovered.

C.The largest and deepest freshwater lake — Lake Baikal.

D.Why does the edge of an ice ring melt faster?

    Time magazine’s tradition —“Person of the Year” originated in 1927, when it honored 25-year-old pilot Charles Lindbergh for the first nonstop solo flight across the Atlantic Ocean Though the magazine has recognized several young people for their global influence, it has never given the important honor to a teenager. But its 2019’s “Person of The Year” is the 16-year-old Swedish climate change activist Greta Thunberg.

Thunberg’s rise to global reputation is even more surprising given that just over a year ago, she was a shy 15-year-old anxious about the increasing threat of climate change. In August 2018, tired of the “refusal” of world leaders to take action, the young girl started camping out in front of the Swedish Parliament every Friday with a sign that said: “School Strike for Climate.”

The teen’s act of protest soon drew public attention, inspiring kids and adults worldwide to take action. By September 2018, her weekly strike became a global climate change movement called “Fridays for the Future”, with tens of thousands of students skipping school on this day to protest the inaction of the leaders of their respective countries. Her appeal for progress in environment protection also encouraged other young activists to begin their own climate change movements.

Varshini Prakash, co-founder of the US Youth-Led Sunrise Movement, says Thunberg “symbolizes the suffering, the frustration, the desperation, the anger — at some level, the hope — of many young people who won’t even be of age to vote by the time their futures are doomed.”

The teenager, who has single-handedly helped bring climate change to the forefront of the global conversation, owes her success to her Asperger’s syndrome (阿斯佩各综合征). She says, “I see the world in black and white, and I don’t like compromising. If I were like everyone else, I would have continued on and not seen this crisis. Right now, we have entered a new decade — a decade that will define our future. And I’ve seen hope, but it does not come from the governments or companies. It comes from the people.”

1.Why did Greta Thunberg camp out in front of Swedish Parliament every Friday?

A.To heighten public awareness of environmental protection.

B.To show her support for school strike for climate.

C.To condemn the government’s inaction on climate change.

D.To win a global reputation as a teenager climate change activist.

2.Where can we find the direct influence of Greta Thunberg’s behavior?

A.In paragraph2. B.In paragraph3.

C.In paragraph4. D.In paragraph5.

3.What kind of girl is Greta Thunberg according to the passage?

A.Positive and sensitive. B.Uncaring but reliable.

C.Selfish but intelligent. D.Brave and determined.

4.We can learn from the passage that _____________.

A.Charles Lindbergh is the first adolescent “Person of the Year” of Time magazine

B.on account of Asperger’s syndrome, Greta Thunberg has suffered a lot

C.all governments haven’t already taken effective measures to deal with climate change

D.Varshini Prakash thinks little of Thunberg and her strike for climate change

How to Become a Lifelong Learner

Learning doesn't stop just because school does. Making a commitment to yourself to learn something new every day, you will not only enjoy what you discover, but you will be able to apply your knowledge and become a teacher to future generations. Here are some steps to become a life­long learner.

Learn how you learn.1.Note what learning techniques are most efficient for you and use them as much as is practical, such as viewing online tutorials on websites like YouTube if you're more of a visual learner.

2.Try many different things so that you don't box yourself into believing you're only good at a few things. It's probable that you're good at many things, but you won't know until you've tried.

Look at learning as an exploration and opportunity, not a chore (琐事)．Don't just force yourself to learn things because they are important or necessary.3. Follow your heart, as well as your sense of duty. Do you remember the 8th grade history that you hated so much, with all those names and dates that seemed to mean nothing? The point was to bring you to learn details now, which will knit chunks of information together later.4.

Read, read, read.5. Reading is a gateway into other worlds and into the minds of your fellow human beings. And reading will help you to learn the discoveries and mistakes of others who have gone before you; reading is, in effect, a shortcut so that you don't have to learn things the hard way.

A.Learn where your talents and interests lie.

B.It was a chore then, but it makes sense, now.

C.Recognize the educational value in whatever you read.

D.Determine your own preferred learning style or styles.

E.Their ways of learning might help you to improve your own.

F.Make friends with your local library and new and used book sellers.

G.Instead, learn things that you need to learn alongside things you love to learn.

    Clothing rental is a hot new industry and retailers (零售商) are demanding to get on board in hopes of attracting green shopper.

But is renting fashion actually more environmentally-friendly than buying it, and if so, how much more? Journalist and author Elizabeth Cline investigated (调查) this question and concluded that it's not as sustainable as it seems.

Take shipping, for example, which has to go two ways if an item is rented — receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint of our collective fashion habit after manufacturing.

She writes, ''An item ordered online and then returned can send out 20 kilograms of carbon each way, and increases up to 50 kilograms for rush shipping. By comparison, the carbon impact of a pair of jeans purchased from a physical store and washed and worn at home is 33.4 kilograms, according to a 2015 study by Levi's.''

Then there's the burden of washing, which has to happen for every item when it's returned, regardless of whether or not it was worn. For most rental services, this usually means dry cleaning, a high impact and polluting process. All the rental services that Cline looked into have replaced perchloroethylene (氯乙烯), a carcinogenic (致癌的) air pollutant, still used by 70 percent of US dry cleaners, with alternatives, although these aren't great either.

Lastly, Cline fears that rental services will increase our appetite for fast fashion, simply because it's so easily accessible. There's something called ''share washing'' that makes people waste more precisely because a product or service is shared and thus is regarded as more eco-friendly. Uber is one example of this, advertised as ''a way to share rides and limit ear ownership.'' and yet ''it has been proven to discourage walking,bicycling, and public transportation use.''

Renting clothes is still preferable to buying them cheap and throwing them in the dustbin after a few wears, but we shouldn't let the availability of these services make us too satisfied. There's an even better step — that's wearing what is already in the closet.

1.What is Elizabeth Cline's attitude toward clothing rental?

A.Approving. B.Unfavorable.

C.Objective. D.Enthusiastic.

2.The Uber example in Paragraph 6 indicates that      .

A.rental services are on the rise

B.clothing rental will be as successful as Uber

C.renting clothes might waste more than expected

D.renting clothes might make people lose interest in fast fashion

3.The author suggests that we should      .

A.give up renting any clothing

B.purchase inexpensive clothes

C.rent clothes rather than buy them

D.make full use of clothes we've possessed

4.What is the passage mainly about?

A.Clothing rental is a new fashion.

B.Clothing rental is retailers' preference.

C.Renting clothes is not that eco-friendly.

D.Renting-clothes business is in a dilemma.

    The driver, Zhang Sal, wandered outside an apartment building in Wuhan, the central Chinese city at the heart of the Coronavirus(冠状病毒) outbreak. He had been ordered not to take food to customers’ doors in order to minimize the risk of infection. But the woman on the phone was pleading, he recalled. The food was for her mother, who couldn't go down to meet him.

Mr. Zhang relented. He would drop off the order and sprint away, As he placed the bag on the floor, Mr. Zhang said, the door opened. Startled, he rushed away. Without thinking, he said, he jabbed the elevator button with his finger, touching a surface he feared could transmit the virus.

That was how Mr. Zhang, 32, found himself speeding back to his delivery station with one finger held high in the air, careful not to touch the rest of his hand-a quarantine in miniature. (小型隔离现场)

For many in China, delivery drivers like Mr. Zhang are the only connection to the outside world. Once a common but invisible presence on the streets of nearly every Chinese city, the drivers are now being praised as heroes.

Throughout China, at least 760 million people-almost a tenth of the world’s population-face some form of household lockdown. The rules are particularly strict in Wuhan, where government efforts to contain the virus have blocked most of the 11 million residents in their homes.

Each household can send someone out for necessities just once every three days. Many residents do not go outside at all, for fear of infection of the more than 2, 100 deaths and nearly 75,000 infections linked to the new virus, the majority have been in Wuhan.

But people still have to eat, which is why Mr. Zhang and many delivery drivers find themselves on the street each day As Wuhan and the rest of China stay at home, they have become the country’s vital arteries, keeping fresh meat, vegetables and other supplies flowing to those who need them.

It is grueling and dangerous work. Mr. Zhang, who works for Hema, a supermarket chain owned by the tech giant Alibaba, crisscrosses the city armed only with the face masks and hand sanitizer that his company supplies each morning.

The epidemic (疫情) has brought some unexpected bright spots. Before, Mr. Zhang said, he sometimes ran red lights during rush hour in order to meet his delivery goals for the day. Now, the streets are empty. He has no problem getting around.

People are nicer, too. Some customers hardly opened the door or avoided eye contact. After the outbreak erupted, everyone said thank you.

1.Why did Zhang Sai wander outside an apartment building in Wuhan? Because______________.

A.He was unwilling to take food to customers ‘doors.

B.He was afraid of being infected by the Coronavirus outbreak.

C.The woman on the phone forbade him to to take food to her door.

D.He was forbidden to take food to customers’ doors.

2.Which of the following can describe the work of delivery drivers after the outbreak of the epidemic?

A.Risky and important. B.Necessary and light-hearted.

C.Easy and creative. D.Valuable and hard-working.

3.What does the underlined part “bright spots” mean in the ninth paragraph?

A.Marks on something. B.Bright places.

C.Difficult situations. D.Good things in a bad situation.

4.Why did people become nicer and say thank you to delivery drivers after the outbreak erupted?

A.Because people need them to deliver necessities.

B.Because people have realized the value of their job.

C.Because of the outbreak of the epidemic.

D.Because of the danger of infection.

    When international aid is given, steps must be taken to ensure that the aid reaches the people for whom it is intended. The way to achieve this may not be simple. It is very difficult for a nation to give help directly to people in another nation. The United Nations Organization (UNO) could undertake to direct the distribution of aid. Here however rises the problem of costs. Also tied with this is time. Perhaps the UNO could set up a body of devoted men and women in every country who can speedily distribute aid to victims of floods and earthquakes.

More than the help that one nation can give to another during a disaster, it would be more effective to give other forms of help during normal times. A common proverb says, "Give me a fish and I eat for a day, teach me to fish and I eat for a lifetime.” If we follow this wise saying, it would be right to teach people from less developed nations to take care of themselves. For example, a country could share its technology with another. This could be in simple areas like agriculture or in more complex areas like medical and health care or even in building satellites. Even a small country is able to help less developed nations. Sometimes what is taken for granted, like the setting up of a water purification plant or the administration of a school, could be useful for countries which are looking about to solve common problems. It does not cost much to share such simple things. Exchange students could be attached for a number of months or years and learn the required craft while on the site. They can then take their knowledge back to their homelands and if necessary come back from time to time to clear doubts or to update themselves. Such aid will be truly helpful and there is no chance of it being temporary or of it falling into the wrong hands.

Many countries run extensive courses in all sorts of skills. It will not cost much to include deserving foreigners in these courses. Besides giving effective help to the countries concerned there is also the build-up of friendships to consider. Giving direct help by giving materials may be effective in the short run and must continue to be given in the event of emergencies. However, in the long run what is really effective would be the sharing of knowledge.

1.The second paragraph is developed mainly_____________.

A.by analysis. B.by process.

C.by example. D.by contrast.

2.Which aid is likely to fall into the wrong hands?

A.A medical team. B.Financial support.

C.A water plant. D.An exchange program.

3.What does the author try to express in the underlined sentence?

A.Providing food is vital. B.Leaning to fish is helpful.

C.Looking after others is important. D.Teaching techniques is vital.

4.What can we infer about international aid from the passage?

A.It is facing difficulties

B.It should be given in the form of materials.

C.It has gained support by developed countries

D.It is unnecessary during normal times.

    Lots of students are unsure about a variety of factors when they consider which college might represent a good fit for them, but they believe they know exactly what they want when it comes to college size.

1.. Here are a few of the less-obvious reasons a smaller school might be a good fit:

1. The professors actually do the teaching. Most small colleges only teach undergraduate degrees.2., and more importantly, graduate students won’t be teaching any of your classes.

2. More focused and direct feedback (反馈). You’ve heard the expression “You’re just a number.” Think about the homework and tests that need to be graded in a class with 450 students. 3.. But at small schools, class sizes are smaller, and professors will have more time to read a student’s work.

3. Research chances. Students at small schools are able to develop relationships with professors more easily, since there is a smaller number of students. 4..

4. Less red tape. It’s just easier to get things done at a small school. 5., and there are fewer regulations. One of the biggest frustrations (令人沮丧的事物) at large schools is that important classes become full quickly, forcing students to either take them over the summer or stay an extra term.

A.Small colleges may offer more sports activities

B.Professors and administrators have more flexibility

C.That means there aren’t graduate students on campus

D.The size of a school really can change your experience

E.It’s great to see students make a 180-degree turn after they visit some small colleges

F.Teachers there don’t have much time to offer advice on every student’s piece of work

G.Most professors know their students’ names and count on them to take part in their research

    Researchers have long known that lack of sleep can cause weight gain and increase other health risks. But for those who force themselves out of bed every weekday after too few hours of sleep, they always hope that turning off the alarm on weekends will repay the weekly sleep debt and change any ill effects around completely.

New research published in Current Biology destroys those hopes. Despite complete freedom to sleep in during a weekend recovery period, participants in a sleep laboratory who were limited to five hours of sleep on weekdays gained nearly three pounds over two weeks. They also experienced metabolic disruption (新陈代谢紊乱). Weekend recovery sleep had some benefits after a single week of lack of sleep. However, those gains were wiped out when people went back into their old schedule the next Monday.

“These health effects are long-term,” said Kenneth Wright at the University of Colorado at Boulder, who oversaw the work. “It’s kind of like smoking once was. People would smoke and wouldn’t see an immediate effect on their health, but now they will say that smoking is not a healthy lifestyle choice. I think “catch-up” sleep is in the early phase of where smoking used to be.”

Michael Grandner, at the University of Arizona, said the study highlights that people need to stop thinking of sleep as a balance sheet (资产负债表). Considerably cutting calories all week and then bingeing on (无节制地吃) a giant pizza on Saturday would not restore balance. That is essentially what people are doing when they skip sleep on weekdays with the idea that they can make up for it on the weekend.

The study suggests people should put sleep first — cutting out the optional “sleep stealers” such as watching television shows or spending time on electronic devices. Even when people do not have a choice about losing sleep due to tight schedules, they should think about sleep first in the same way they would a healthy diet or exercise.

1.Why do people hope to sleep longer on weekends?

A.To avoid some debt concerns. B.To cure some illness.

C.To get some health benefits. D.To get complete freedom.

2.What can we infer about weekend recovery sleep from Kenneth Wright?

A.It has the long-term benefits. B.It hides some potential harm.

C.It causes smoking problems. D.It contributes to losing weight.

3.What does the text suggest people do about sleep?

A.Sleep well every day. B.Guarantee weekly sleeping hours.

C.Make up for missing sleep. D.Stop watching TV shows before bed.

4.What can be a suitable title for the text?

A.Weekend “Catch-Up Sleep” Is a Lie.

B.Watch out for "Sleep Stealers".

C.Sleep and Smoking are alike.

D.Lack of Sleep Does No Good.

    I have been reading about Leonardo da Vinci for decades, and in 1994 I bought one of the notebooks, in which Leonardo recorded his thoughts and outlined ideas.

What does a Renaissance(文艺复兴) artist have to do with optimism? For me, the connection is innovation. I feel optimistic about the future because I know that advances in human knowledge have improved life for billions of people, and I am confident they will keep doing so. Although I am no art expert, everything I have learned about Leonardo leads me to believe he was one of the most innovative thinkers ever.

Today of course Leonardo is most famous for paintings like the Mona Lisa and The Last Supper. But in his mind, Leonardo was not primarily a painter. He thought of himself as an engineer first. In a letter to the ruler of Milan listing his strengths, sent in the early 1480s, Leonardo mentioned ten different skills — designing bridges, tunnels, for example — before adding at the end that he could also paint.

Leonardo was a never-ending learner. He studied everything he could see: the flow of water, the way smoke rises through the air, how a bird uses its tongue. And he had insights that were ahead of his time. He was the first person to correctly explain why you can see light between the two points of a crescent moon, the phenomenon we now call earthshine.

Scientific inquiries like these were essential to Leonardo’s art. He was able to give the Mona Lisa that mysterious look on her face because he had studied all the muscles involved in smiling. In The Last Supper, he could make the perspective lines (透视线) work perfectly because he had spent countless hours understanding how our eyes see objects at a distance. By examining his surroundings so closely, Leonardo was able to develop new techniques that advanced his field and described the world in a way no one had ever seen before. In other words, he was an innovator.

1.In what way does Leonardo da Vinci make the author feel optimistic about future?

A.The creativity he represents. B.His famous paintings.

C.The outline of his notebook. D.His engineering achievements.

2.What can we learn about Leonardo da Vinci according to the text?

A.He desires to know more at all times.

B.He is able to raise difficult questions.

C.He has a strong desire for achievement.

D.He is able to learn and understand things fast.

3.What does the last paragraph focus on?

A.Which fields Leonardo was expert in.

B.Why Leonardo is regarded as an innovator.

C.What made the Mona Lisa and The Last Supper stand out.

D.How Leonardo applied scientific theories to his paintings.

4.Which of the following can best summarize Leonardo da Vinci according to the text?

A.Curious about arts. B.Talented in many fields.

C.Determined in science. D.Skilled in paintings.

    When I first catch sight of Greta Thunberg, it is eight in the morning, and a small crowd has already gathered. It is a Friday, her day of protest, and the 16-year-old is standing outside the parliament(议会) building, next to a sign saying “School strike for climate” in Swedish.

This is the 26th week of her protest, which has taken place every Friday since school started last August. Her goal is to bring Sweden in line with the 2016 Paris Agreement, which promises to limit global warming to below 2℃, compared with pre-industrial levels.

Over the past six months, Greta has rocketed to a level of fame and influence that pretty much nobody, including herself, expected. Her protest was quickly highlighted by the media. Then came a TED talk and an invitation to address last December’s U.N. climate talks in Poland.

While Greta may seem an unlikely climate activist, it was not entirely accidental that she became one. Like many children, Greta watched educational films about the melting Arctic and the fate of the polar bears and the marine mammals bloated (肿胀) with plastic. But unlike other children, she couldn’t let them go. “I became very affected. I began thinking about it all the time.” said Greta.

Greta began researching climate change and has been staying on the topic for six years. She has stopped eating meat and buying anything that isn’t necessary. In 2015, Greta stopped flying on airplanes, and a year later, her mother followed her example, giving up an international performing career. The family has started growing their own vegetables on his own garden outside the city. To meet me in central Stockholm, Greta and her father rode their bikes for about half an hour, although the family has an electric car that they use only when necessary.

1.What can be inferred from the second paragraph?

A.Industry in Sweden is developing too fast.

B.School climate education remains to be improved.

C.The climate around the world has increased by 2℃.

D.Sweden should do more to meet the Paris Agreement.

2.Why did Greta become the focus of media attention?

A.She was expected to be famous.

B.She was invited to the TED talk.

C.She skipped school for the protest.

D.She was active in the protest as a child.

3.What makes Greta devoted to climate activities?

A.The educational programs.

B.Her speech at U.N. climate talks.

C.Her great concern about climate change.

D.The protest of “School strike for climate”

4.What happened after Greta became a climate activist?

A.She moved to the countryside.

B.She had an eco-friendly life.

C.She followed her mother’s example.

D.She gave up her work for her research.

The sound of music

The Calgary Folk Music Festival (25-28 July) was born 40 years ago, and has grown from a grassroots event to a celebration that brings together thousands of musicians, artists and fans. The festival is held in Princes Island Park and its relaxed, welcoming atmosphere makes it a great spot in the sun while enjoying some quality folk music.

Want to keep the music playing? Head to Studio Bell, where the new National Music Centre hosts regular exhibitions and concerts.

Green city

Though it’s a relatively short drive to the legendary Rocky Mountains, Calgary itself is also filled in greenery.

A comprehensive network of urban pathways offers walkers and cyclists an urban oasis and an eco-friendly way to get around the city’s neighborhoods. Take a slow walk or cycle downtown along the riverside or walk across the futuristic Peace Bridge to explore the urban village，of Kensington. Alternatively, take in the scenic views and sunshine by rafting(乘筏) down the mighty Bow River instead.

From farm to patio

Calgary is home to a farm-to-table scene. Discover the whitewashed brick walls and nose-to-tail philosophy in the Model Milk, while plant-lined ceilings and a vegetable menu await in bright and airy Ten Foot Henry.

Calgarians take their beer as seriously as their steak and it wouldn’t be summer in Calgary without a good patio-hopping session. Start off at 17th Avenue institution The Ship & Anchor, then make your way to Cold Garden. Don't fancy walking? Explore the city’s craft-beer scene by bike with Urban Pedal Tours.

1.What can we learn about the Calgary Folk Music Festival?

A.It lasts three days in July every year.

B.It is a celebration for grassroots musicians.

C.It has a history of less than 40 years

Dear Ms Smith，

I’m writing to ask whether you could do me favor. I’ve just finished an essay naming “Differences between traditional Chinese and Western festivals”，so I’m not sure whether it is well written. To be honestly，I’m not that familiar with some traditional Western festivals. That’s because I’m turning to you for help. I’d appreciate it if you could spare some time to look through your essay for possible mistakes and polish them. Also，I’m looking forward to your valuable advices. My essay has been sending to you along with this email. I hope it won’t cause you very much more trouble.

Thank you by advance.

Yours sincerely，

    It affects one in six people in England each week. That’s the rate of people who report experiencing a common mental health problem，such as depression. Whether temporarily down or depressed，many rely on anti­depressants(抗抑郁药) to lift their mood. But they have a cost—one ex­user said that they felt they were in a “chemical fog” and were desperate to stop. 1. what alternatives are there when you’re feeling truly blue?

2.Sarah，who had been taking anti­depressants since the age of 17，is now off all medication and swimming—something that may be an effective treatment for depression. Apart from the exercise and companionship of swimmers，the cold water puts the body under stress. With repeated immersions(沉浸)，the body better adapts not just to this physical stress，but mental stress，including the psychological problems of life that lead to low spirits.

Susan Calman relies on kindness to brighten her mood. The 43­year­old comedian and author encourages others to use kindness to improve the lives of those around them. “It can be as simple as holding open a door for someone，or giving someone praise，or buying someone a packet of crisps while they’re feeling down，” she says. 3..

    Daniel Anderson，a famous psychologist，believes it's important to distinguish television's influences on children from those of the family.We tend to blame TV，he says，for problems it doesn't really cause，overlooking our own roles in shaping children's minds.

One traditional belief about television is that it reduces a child's ability to think and to understand the world.While watching TV，children do not merely absorb words and images (影像)．Instead，they learn both explicit and hidden meanings from what they see.Actually，children learn early the psychology of characters in TV shows.Furthermore，as many teachers agree，children understand far more when parents watch TV with them，explaining new words and ideas.Yet，most parents use an educational program as a chance to park their kids in front of the set  and do something in another room.

Another argument against television is that it replaces reading as a form of entertainment.But according to Anderson，the amount of time spent watching television is not related to reading ability.TV doesn't take the place of reading for most children；it takes the place of similar sorts of recreation，such as listening to the radio and playing sports.Things like parents' educational background have a stronger influence on a child's reading.“A child's reading ability is best predicted by how much a parent reads，”Anderson says.

Traditional wisdom also has it that heavy television­watching lowers IQ (智商) scores and affects school performance.But here，too，Anderson notes that no studies have proved it.In fact，research suggests that it's the other way around.“If you're smart young，you'll watch less TV when you're older，”Anderson says.Yet，people of lower IQ tend to be lifelong television viewers.

For years researchers have attempted to show that television is dangerous to children.However，by showing that television promotes none of the dangerous effects as conventionally believed，Anderson suggests that television cannot be condemned without considering other influences.

1.By watching TV，children learn ________.

A. images through words

B. more than explicit meanings

C. more about images than words

D. little about people's psychology

2.An educational program is best watched by a child ________.

A. on his own    B. with other kids

C. with his parents    D. with his teachers

3.Which of the following is most related to children's reading ability?

A. Radio­listening.

B. Television­watching.

C. Parents' reading list.

D. Parents' educational background.

4.What is the main purpose of the passage?

A. To advise on the educational use of TV.

B. To describe TV's harmful effects on children.

C. To explain traditional views on TV influences.

D. To present Anderson's unconventional ideas.

    Barcelona’s famous Segrada Familia is finally set to get a building license to work on the still uncompleted church.

This UNESCO World Heritage basilica(长方形基督教堂)，which is Barcelona’s most visited tourist attraction，began building in 1882 based on a design by architect Francisco Lozano. However，when he stepped down，architect Antoni Gaudi took over the design in 1883.The building won’t be finished until 2026—one hundred years after the architect was killed by a streetcar in the city. His body was buried in a room under the floor of the Sagrada Familia.

To get its paperwork rubber stamped，the church authorities have agreed to finally pay the government a 36 million fee for a building permit. Gaudi was told to get the paperwork processed，but the architect failed to do so—proceeding with construction. The money from the church’s permit will be used to upgrade transport links and beautify the area.

Gaudi played an active role in directing the construction of the Sagrada Familia until his death in 1926.He would often request that work be modified and adjusted until it was exactly what he had in mind. However, interpretation of the designs by present day architects is particularly challenging because of the nature of the existing designs.

Gaudi and his works have become symbols of Barcelona，the capital city of Catalonia，northeast Spain. The unfinished building is called a masterpiece of Gothic architecture and it is perhaps the most unique and mysterious building in the style ever constructed. The popularity of the site with tourists has helped fund the push to complete the church and pay for the paperwork.

1.What do we know about the Segrada Familia?

A.It has been completely constructed. B.It was first designed by Antoni Gaudi.

C.It will get a building permit in 2026. D.It began to be built 138 years ago.

2.What can we infer about Antoni Gaudi?

A.He wished to be buried in the church. B.He is remembered as a great architect.

C.He didn’t know a permit was necessary. D.He is to blame for the unfinished church.

3.What makes the Segrada Familia so popular?

A.Its unusual design style. B.Its two famous architects.

C.Its special building materials. D.Its illegal construction paperwork.

4.The church managed to pay for the license _________.

A.in the support of the government B.by reducing construction costs

C.with the aid of tourist income D.through donations from architects

    For some years，my mother worked for a charity as President and Secretary.Selling raffle tickets(兑奖券) was her main means of bringing in the charity’s much­needed funds.We girls would accompany her，selling tickets with great success.My father made and donated beautiful wooden toys，jewellery boxes and other lovely items as prizes.

Now my sister was always coming up with “good ideas”，most of which didn’t work out to plan.But that didn’t deter her.She had many just waiting to be tested.When she was eight and I was just five，we had a wonderful idea for a business adventure.We decided we would sell raffle tickets for charity，and that charity was us!

So one afternoon，we told our mother we were going to play in the park with our cousins as we did most days after school.But instead，we walked around the streets armed with a raffle book，a pen and a large cloth bag to carry the money.

We’d accompanied our mother many times when she sold tickets，so people were familiar with us when we appeared at their doors.Despite the blank looks they received when asking about the prizes on offer，they were very generous.Although there were no actual prizes，our mother’s previous track record enabled us to sell nearly the whole book of raffle tickets.

Like a little pair of lottery(彩票) winners，we walked home and proudly showed off our takings.But our enjoyment of this sudden wealth was short­lived，and our plans for spending it quickly failed.Our angry mother took us back to every ticket buyer，making us apologise and give the money back.Thankfully，our sweet neighbours didn’t make a big deal of our “clever” misbehavior and thus my mother’s

fundraising career could continue safely.We were taught a good lesson by our mother that day.Also I remember my sister’s entrepreneurial(企业家的) spirit dried up a bit after that.

1.What did the author’s father do?

A.He got prizes ready. B.He sold hand­made items.

C.He was in charge of a charity. D.He helped design raffle tickets.

2.What does the underlined word “deter” in Paragraph 2 mean?

A.Embarrass. B.Shock.

C.Discourage. D.Mislead.

3.What can be learned about the author and her sister while selling raffle tickets?

A.They ran into their mother.

B.They met some generous strangers.

C.They got lost while walking around the streets.

D.They took advantage of people’s trust in their mother.

4.What lesson did the author and her sister learn?

A.Honesty is the best policy. B.What’s done can’t be undone.

C.Misfortune never comes alone. D.Good advice is beyond all price.
