Tests have shown robots can diagnose heart problems in as little as four seconds, as a review of artificial intelligence （Al） finds machines are now as good at spotting illness as doctors.

Analyzing a patient's heart function on a cardiac MRI （心脏磁共振成像）scan currently takes doctors around 13 minutes. But a new trial by University College London （UCL） showed an Al program could read the scans in less time with equal accuracy. There are approximately 150,000 such scans performed in the UK each year, and researchers estimate that fully using Al to read them could save 54 clinician-days （临床天数）at each cardiac centre per year. So it can make up for the shortage of doctors.

It is hoped that Al where computer systems are able to learn from data to identify new patterns with minimal human intervention will transform medicine by helping doctors spot dis- eases such as heart disease and cancer faster and earlier. However, most scans are still read by specially trained doctors.

Dr Charlotte Manisty, who led the UCL research, said, "Cardiovascular MRI offers in- comparable image quality for assessing heart structure and function. However, current manual  analysis remains basic and outdated. Automated machine techniques offer the potential to change this and completely improve efficiency and accuracy, and we look forward to further research that could confirm the superiority to human analysis."

She added, “Our dataset of patients with a range of heart disease who received scans enabled us to demonstrate that the greatest sources of measurement errors arise from human factors. This indicates that automated techniques are at least as good as humans, with the potential soon to be  'super-human'—transforming clinical and research measurement precision."

Professor Alastair Denniston said, "Within those handful of high-quality studies, we found that by deep learning Al could indeed detect disease ranging from cancer to eye disease as accurately as health professionals. But it's important to note that it did not absolutely exceed human professional diagnosis. ”

1.Which of the following can best describe this Al program?

A.Time-consuming. B.Environmentally friendly.

C.Extremely unpractical. D.Labor-saving.

2.What is Charlotte Manisty's expectation of automated machine techniques?

A.To treat eye disease faster and earlier.

B.To analyze heart disease efficiently and accurately.

C.To combine manual with automated analysis.

D.To confirm heart structure and function.

3.What did Alastair Denniston say about Al?

A.It would be super-human soon.

B.It couldn't completely replace expert doctors.

C.It would correct professionals' measurement errors.

D.It couldn't detect cancer as accurately as health professionals.

4.What is the main idea of the text?

A.Al has many shortcomings in practice.

B.Al totally shows its superiority to human analysis.

C.Al can reduce medical errors arising from human factors.

D.Al can diagnose heart disease as well as doctors in less time.

    You should try your best to create your own family library so that you and your family are always learning. "It is a great mistake to think that education is finished when young people leave school. Education is never finished even if you grow older," said Mrs Child in The Mother's Book. "Collecting a library of books in your home is really helpful to your family. ”

"What is really interesting about having so many books in your home is that a book you purchase has a chapter about the deeper knowledge of your favorite subject at school," said a university graduate. Researchers in a study tries to identify what parents do has an influence on how well their children do on standardized tests. One positive aspect they find is the availability of a large number of books at home. This has a stronger connection, especially when you read to your children every day. The more books your older kids have access to at home, the more likely they are just to be reading for fun, rather than having to wait for weekly trips to the library.

John Henry, one educated parent, said, "I have been homeschooling my children using the philosophy of A Thomas Jeffer son Education. This philosophy of learning is based on the reading of classic books. ” Clinton Fadiman said, "When you reread a classic, you do not see more in the book than you did before； you see more in you than before. " Classic books also make you smarter and wiser! The wisdom comes in the examples in the lives of the characters.

"It is within your power to guide your youth in their reading and to cultivate in their hearts a desire for good books. It is the most unfortunate if a person is not possessed with the desire for good reading. The reading habit, like charity, should begin at home," said Mrs Child.

1.What does the author mainly want to show in paragraph 2?

A.Kids don't need to go to the library any longer.

B.Parents should set a good example at home.

C.It's necessary to create a family library.

2.How does the author explain the effect of reading classic books at home in paragraph 3?

A.By quoting others ’words. B.By questioning.

C.By imagination. D.By analyzing research data.

3.What can we learn from what Mrs Child said?

A.East or west, home is best.

B.One is never too old to learn.

C.He who makes no mistakes makes nothing.

D.Charity is the soul, rather than the virtues of hand.

4.What can be the best title for the text?

A.Where to Store Your Favorite Books at Home?

B.When to Read the Classic Books to Your Children?

C.Which Is Better, a Home Library or a Public Library?

D.Why Not Have Your Own Library of Books at Home?

    As I drove along the road, a small car flew across the center divider from the opposite direction and crashed into my car head-on, I fainted and was awakened by the ringing of my mobile phone.

I was brought to Kuala Lumpur General Hospital bleeding on from my nose, mouth and legs. But the hospital staff was too busy to attend to me, so I called a friend to tell him about the accident. Some friends arrived very soon and sent me to a private hospital nearby. I saw my injured feet hanging from my body, blue and lifeless, and I begged the doctors to save them at all costs. They calmly promised to do their best.

The doctors made it. After I was discharged, I was given ten months medical leave. My heart sank, knowing that it meant I, a big man, couldn't work. How was I going to support my 65-year-old mother and other family members? I felt completely helpless, but a lot of unexpected blessings came my way. I had many visitors during my 14 days in hospital and when I was recovering at home. Friends and relatives helped me with my banking, insurance or simply came to cheer me up.

When the casts （石膏）were removed, I did not let the sight of my weak legs discourage me. I worked hard at my physiotherapy （物理疗法）with only one aim. After eight months, I was walking without the aid of a walking stick. On February the following year, I returned to my job again. Today, after eight years, I have travelled to many countries as a tour leader.

The accident makes me realize how lives can change in a split second. I value life more, not only of my own but also of everyone I know, and I will always try to help when I know of someone in trouble.

Tips to Increase Your Productivity

Want to get more done in your day? Of course you do. 1.The good news is that everyone can increase the amount of tasks they accomplish in a day. Here are some tips to help you have a more productive day.

Make a plan for your day. Make sure you know how you want your day to go in advance, even before you start. 2. To work best, create the next day’s plan the night before so that every morning you spend time performing, not planning.

Break large tasks down into bits accomplished easily. Do you have a large project that’s just so big that you keep putting it off? Or maybe you’re just unsure of where to begin, so you put it off. 3.Therefore, you will feel a sense of accomplishment as you check the items of your list.

Always set your priorities (优先事项). 4. Figure out what must be done, do that first and rank the rest of your work according to importance. If you don’t get to the items at the end of your list, it won’t be a big problem, and you can do them another time.

5. If you are the most productive in the morning, that’s when you should hit it hard and do as much as you can. If you work better in the afternoon, take care of some things like emails in the morning and then accomplish the important projects in the afternoon. Keep on top of your work habits, and you’ll be more productive.

A. Reward yourself if you are productive.

B. This can provide you a roadmap for the day.

C. Be aware of when you are the most productive.

D. It’s tough to meet depressed people who are productive.

E. It’s important to accomplish the most important tasks first.

F. A good way is to break the project down into more manageable ones.

G. To stay competitive in any industry, you need to improve your productivity.

    According to new research from the University of Cambridge in England, sheep are able to recognize human faces from photographs. The farm animals, who are social and have large brains, were previously known to be able to recognize one another, as well as familiar humans. However, their ability to recognize human faces from photos alone is novel.

The recent study shows the woolly creatures could be trained to recognize still images of human faces, including those of former President Barack Obama and actress Emma Watson.

Initially, the sheep were trained to approach certain images by being given food rewards. Later, they were able to recognize the images for which they had been rewarded. The sheep could even recognize images of faces shown at an angle, though their ability to do so declined by about 15 percent—the same rate at which a humans ability to perform the same task declines.

“Anyone who has spent time working with sheep will know that they are intelligent, individual animals who are able to recognize their handlers,” said Professor Jenny Morton, who led the Cambridge study. “We’ve shown with our study that sheep have advanced face-recognition abilities, comparable with those of humans and monkeys.”

Recognizing faces is one of the most important social skills for human beings, and some disorders of the brain, including Huntington’s disease, affect this ability. “Sheep are long-lived and have brains that are similar in size and complexity to those of some monkeys. That means they can be useful models to help us understand disorders of the brain, such as Huntington’s disease, which develop over a long time and affect cognitive abilities. Our study gives us another way to monitor how these abilities change,” Morton said.

1.According to the new research, what’s unusual about sheep?

A.They have large brains.

B.They can recognize their owners.

C.They can tell animals from humans.

D.They can recognize human faces from photographs.

2.How did the researchers train the sheep?

A.By giving food rewards.

B.By showing photos of famous people.

C.By guiding them to follow their handlers.

D.By showing photos of humans and monkeys by turns.

3.What can be inferred from the passage?

A.Sheep have a higher face-recognition ability than monkeys.

B.Sheep recognize faces same well when shown photos at any angle.

C.The new discovery is beneficial to the study of cognitive ability changes.

D.The sheep’s face-recognition ability may prevent some disorders of the brain.

4.What’s the best title of the passage?

A.A Wonderful Scientist

B.The Life of Sheep

C.The Sheep’s Recognition of Each Other

D.A New Discovery about Sheep

    Air travel can be annoying. But research now suggests global warming could make it much worse. To get off the ground in really hot weather, planes may be forced to carry fewer passengers. That might mean a little more space, which would be good. However, it also would make the passengers pay more.

Average air temperatures around the world are rising because people are polluting the air with increasing amounts of greenhouse gases, which, such as carbon dioxide, are a byproduct of burning fuels. Those warmer temperatures can influence an airplane’s ability to fly because air molecules (分子) spread out more as the air warms. This produces less lift under a plane’s wings, so a plane must be lighter to take off in hot weather than on cooler days.

It can even prove too dangerous for some planes to attempt a take-off. A record of June heat wave in the American Southwest, for instance, caused flight cancellations in Phoenix, Ariz. One airline ‘s planes were cleared to operate only up to 47.8℃. On June 20, Phoenix reached 48.3℃!

Radley Horton is a climate scientist at Columbia University. Two years ago, he and his graduate student Ethan David Coffel studied the effect of warming at four US airports and found that warming of track could triple (使成三倍) the number of days when planes face weight restrictions. Later, they explored the effect of rising temperatures on five types of commercial planes flying out of 19 of the world’s busiest airports. In the coming decades, as many as one to three out of every 10 flights that take off during the hottest time of day could face weight restrictions, they found. In some cases, a typical 160-seat plane would have to remove 4％of its weight. That would be equal to taking a dozen people off the plane, the researchers calculated.

1.How would global warming affect air travel according to the first paragraph?

A.It’ll add to the danger of flying.

B.It’ll increase passengers’ travel cost.

C.It’ll make flying much more comfortable.

D.It’ll encourage more people to travel by plane.

2.What is the second paragraph actually intended to explain?

A.How global warming is happening. B.What decides a plane’s ability to fly.

C.Why global warming affects flying. D.Where greenhouse gases are created.

3.What is the last paragraph mainly about?

A.Reasons for flight cancellation. B.Financial condition related to hot air.

C.The tendency of temperature change. D.Findings of effects of warming on flying.

4.What should be the best title for the text?

A.Air Travel isn’t Recommended during Hot Weather

B.Rising Temperatures May Reduce the Number of Flights

C.Weight Restrictions Are More Common in More Airports

D.Hotter Air May Lead to Planes Carrying Fewer Passengers

    When 6-year-old Jack Foley crossed the finish line last month at the Long Beach Kids Triathlon, it was more than an athletic achievement. His completion marked a remarkable recovery from a rare heart condition.

The journey began before Jack was born.

At a routine 20-week examination, doctors told parents-to-be Rob Foley and Lauren Kiefer-Foley of Long Island, New York, that the fetus’ (胎儿的) heart wasn’t properly developing. “The doctor told us, ‘we can’t see the left side of the baby’s heart,’ Kiefer-Foley recalled.” He told us, “you need to get to a cardiologist (心脏病专家) first thing in the morning.”

Further tests would confirm a diagnosis of hypo plastic left heart syndrome, a rare birth fault affecting the heart’s ability to pump blood through the body. Doctors informed the couple about the risks and challenges their child could face. “We were advised by many doctors to terminate our pregnancy because the condition is so severe. They told us that most babies don’t even survive birth, let alone the first surgery,” Kiefer-Foley said.

Nonetheless, the couple decided to give their baby a chance.

After Jack was born at full-term via a scheduled C-section (剖腹产), doctors took him straight to a care unit to administer the level of care he would need before his first open-heart surgery days later. “When the doctor said ‘it’s a boy!’ I didn’t get to see him for hours after that.” Kiefer-Foley said. They would also have to wait until after Jack’s first surgery to hold him for the first time.

With a successful delivery behind them, it was now up to Dr. Emile Bacha, chief of Morgan Stanley Children’s Hospital to guide Jack through a series of surgeries to repair the newborn’s heart.

1.Why did the author say “it was more than an athletic achievement” in Paragraph 1?

A.Jack was only six years old.

B.The event was too difficult.

C.Jack once suffered from severe heart disease.

D.Jack didn’t recover from severe heart disease.

2.What was the bad effect of Jack’s disease?

A.It led to inadequate blood supply. B.The beat of heart was not heard.

C.His intelligence will not develop properly. D.The right side of the baby’s heart can’t be seen.

3.What does the underlined word “terminate” in Paragraph 4 refer to?

A.continue B.stop

C.change D.adjust

4.What will most probably be talked about in the next part of the text?

A.Jack’s journey all over the world.

B.The sorrow and despair of Jack’s parents.

C.Jack’s major academic achievement.

D.Jack’s remarkable recovery from heart disease.

    Whether you volunteer at an animal shelter or in a hospital, volunteering is a wonderful opportunity to bring good into the world and support your community. There are a lot of different volunteer opportunities. 1. Here are some tips on how to be an even better volunteer.

Volunteer for something you love. 2. If your passion is helping those with cancer, volunteer to raise money for research. If you’re passionate about improving the environment, volunteer to pick up trash in public places. Your passion will keep you motivated, so put your effort into something you treasure.

3. You are probably not best suited for directing traffic if you are shy. Be respectful to those organizers, but let them know your strengths and show them how your strengths can be beneficial in your volunteer work. Find the balance that brings your talents to the table and really helps the organization.

Be on time. This is a simple but important idea. Think about being late for your work; your boss, coworkers and customers would be upset. The same applies to volunteering. 4.

Mix your volunteer jobs. If you become bored, it may be time for a schedule change in your life. 5. It is volunteering, so you aren’t stuck in one place.

A.Offer what you can do best.

B.Ask what’s expected of volunteers.

C.So if such a thing does happen, just call and let them know.

D.It doesn’t matter what it is, but it does matter what you like.

E.Therefore, everyone can find a volunteering opportunity that suits their skills and interests.

F.However, you will volunteer longer in an organization that supports a cause you care about.

G.Volunteer on different days or ask for different tasks to see what other opportunities are out there.

    (The New York Times, Oct.7) The 2019 Nobel Prize in physiology(生理学) or medicine was jointly awarded to three scientists — William G. Kaelin Jr., Peter J. Ratcliffe and Gregg L. Semenza — for their work on how cells sense and adapt to oxygen availability. The Nobel Assembly announced the prize at the Karolinska Institute in Stockholm on Monday.

Their work established the genetic mechanisms(机制) that allow cells to respond to changes in oxygen levels. The findings have implications(启示) for treating a variety of diseases.

Why did they win?

“Oxygen is the lifeblood of living organisms(生物体),” said Dr. George Daley, dean of Harvard Medical School. “Without oxygen, cells can’t survive.” But too much or too little oxygen can be deadly. The three researchers tried to answer this question: How do cells regulate their responses?

The investigators uncovered detailed genetic responses to changing oxygen levels that allow cells in the bodies of humans and other animals to sense and respond to fluctuations(波动), increasing and decreasing how much oxygen they receive.

Why is the work important?

The discoveries reveal the cellular mechanisms that control such things as adaptation to high altitudes and how cancer cells manage to hijack(攫取) oxygen. Randall Johnson, a member of the Nobel Assembly, described the work as a “textbook discovery” and said it would be something students would start learning at the most basic levels of biology education.

“This is a basic aspect of how a cell works, and I think from that standpoint alone it’s a very exciting thing.” Johnson said.

The research also has implications for treating various diseases in which oxygen is in short supply — including anemia, heart attacks and strokes — as well as for treatment of cancers that are fed by and seek out oxygen.

1.This research has won the Nobel Prize mainly because ____________.

A.there was no research of this kind in the past

B.oxygen is the lifeblood of living things

C.it has uncovered how cells sense and respond to changes in oxygen levels

D.various diseases will be cured with the help of the findings of the research

2.We can learn from the passage that _____________.

A.The Nobel Prize was awarded to a physiologist on Monday in Sweden.

B.Cancer cells manage to hijack oxygen and need oxygen to develop.

C.The more oxygen there is in blood, the healthier a living body will be.

D.The genetic mechanisms have been found that allow oxygen to adapt to cells.

3.Which of the following can best explain the underlined word in the text?

A.used for textbooks B.powerful and authoritative

C.typical as a perfect example D.basic and clear

4.In which part of The New York Times can you find this article?

A.Entertainment B.Culture

    Recently, the most heated topic of “which is the right bin for my garbage” has swept China.

Shanghai is among China’ s first cities to introduce garbage classification (垃圾分类) and also the country’s most serious in its performing. Since July 1,2019, Shanghai residents have been required by law to sort garbage into four different categories, or they could face fines. Individuals, including tourists, can be fined 200 yuan for failing to sort their waste properly, while companies and institutions can be fined up to 50,000 yuan.

The government has set up online apps to handle sorting questions, and announced guidelines to address the “one-size-fits-all” method. The country is about to invest over 21 billion yuan in the construction of garbage processing facilities to meet demands. Now it’s introducing artificial intelligence into its waste management system, by setting up little cameras in many sets of bins.

However, not every face can be recognized by the smart dustbin until you register for the system. Once registration is complete, users will scan a QR code on the bin, which then opens it up to allow for garbage disposal (处理). Now, each household gets one special QR code for throwing out waste. Here, the intelligent bins don’t just calculate garbage weight, they also help residents gain rewards by collecting points through the special app.

China is stepping into the age of compulsory garbage sorting with its cities revising laws on garbage classification. For Shanghai, sixty percent of the city is expected to carry out garbage sorting by the end of 2019, and 90 percent by 2020. Garbage sorting is, without doubt, a costly but worthwhile endeavor. It is good for the environment and important for the country’s sustainable development (可持续发展), and may finally turn out to be a promising industry as well.

1.What is the correct order in using smart garbage sorting system?

① Gain rewards.       

② Open up the bin

③ Register for the system.       

④ Scan a QR code on the bin.

A.③④②① B.④②③①

C.③①②④ D.④③②①

2.What does the underlined word “endeavor” in the last paragraph mean?

A.Effort. B.Fashion.

C.Announcement. D.Decision.

3.What can we know from the text?

A.The intelligent bins can only show garbage weight.

B.Residents have to sort garbage into four different categories in Shanghai.

C.If companies forget to sort their waste, they can be fined 200 yuan.

D.Tourists can avoid being fined for failing to sort their waste correctly.

4.Why does our country push ahead with compulsory garbage sorting?

A.To build a garbage sorting system.

B.To increase the use of artificial intelligence.

C.To promote sustainable development of environment.

D.To support the construction of garbage processing facilities.

    Very early on in my senior year of high school, my parents carried the flame of worrying about my future college. I was willing to go to a 2-year college before going after my bachelor, s degree. This was for two reasons—to help them save money and to make sure I major in English. However, they insisted I attend a 4-year college right off the bat.

I was pushed to start searching for colleges therefore, ones that my parents approved of and that were within the range of tuition that my mom thought was acceptable. I was also limited to the immediate areas, which only included New York, Connecticut, Pennsylvania, and New Jersey, so I cannot apply for any colleges in one of my favorite places—New Hampshire.

I’ll be honest. It got a bit tense at times with several different opinions between my parents and me, and with other family members or friends voicing their thoughts to my parents.

In the end, I ended up applying for three schools—SUNY Albany, SUNY New Paltz and Kutztown University in Pennsylvania. I had been to New Paltz quite often as it was only 45 minutes away from our home. And Kutztown is located in an area our family often visited.

I was accepted by all three, and I quickly gave up Albany. I was not impressed with the city and wasn’t familiar with the area. It was between New Paltz and Kutztown. After a few weeks, I ended up settling on New Paltz because Kutztown just didn’t “feel right” for me. When I was on campus, I had a feeling that this was it.

Looking back now, I wish I had known more about the application process and had a little more freedom of choice about which college I could apply for. I probably would still have attended SUNY New Paltz.

1.What did the author’s parents think he should do?

D.He wasn’t sure whether or not he would fit in there.

3.How did the author feel about his final choice?

A.Embarrassed. B.Frightened.

C.Satisfied. D.Worried.

4.What is the best title for the text?

A.How I chose my college B.How to apply for a college

    The Tang Dynasty, which lasted from 618 to 907 AD, is often considered as China’s golden age. Indeed Chinese culture flourished under the Tang, and Tang poets are perhaps the best known of all Chinese literary figures.

The following are four schools of Tang poetry. Take a look.

Frontier Fortress Poetry (边塞诗)

Gao Shi, Cen Shen and Wang Changling are representatives of this poetry. It mainly describes the hardship of the battlefield, heroic spirit of defending the homeland, or homesickness of soldiers. Representative works include Over the Borcfer by Wang Changling, Song of Write Snow on Secretary Wu’s Return to Capital by Cen Shen, etc.

Landscape Pastoral Poetry

The representatives of this school are Wang Wei and Meng Haoran. Many of its themes are mountains,clouds and hermits (隐士). Its style is simple and elegant. The representative works include Thinking of My Brothers on Mountain Climbing Day by Wang Wei, Spring Morning by Meng and so on.

Romantic Poetry

Li Bai is a typical representative of romantic poetry, who enjoys the title of “Genius of Poetry”. To express his desire for freedom and personal value, his poetry is free and bold, with creative imagination. One of his most famous poems is A Tranquil Night, which is about homesickness, included in many school textbooks.

Realistic Poetry

Du Fu is known as the “Sage of Poetry”. His poems are in a realistic art style with strong feelings of compassion and concern for the destiny (命运) of the country. His works “Three Officials” and “Three Farewells” both reflect people’s sufferings at that time.

How to Love Year Parents

Even if you think that your parents are mean-spirited (小心眼的) at times, loving your parents is a normal and fulfilling part of life. You love them for the fact that they created you, raised you, and are in part, a source of who you are.1..

Tell them you love them every morning. A gentle “good morning” and “I love you” will warm a coldest heart. Remember that they brought you into this world. Without your parents, we might still wander at an unknown corner in an unknown world.

Respect them more and cherish these moments. You can use these moments to learn from them, preparing yourself for when you’re off on your own. It’s OK to get angry but angry actions don’t help you or your parents. Act calmly, cool off, write down your feelings, or talk to a friend.2..

Obey their requests. It will make your attitude better and earn you more respect from them. It may seem as if you are going through hell when you don’t get what you want or you have to clean. However, you had better remember they keep a roof over your head when it’s cold, raining, snowing, or too hot. Understand that parents are human beings and make mistakes.3.Since you can forgive your friends, why not forgive your parents?

Keep company with them. Do things with your parents like watching TV, or go somewhere with them.4.Listen to their old stories and learn from them. You will find they are your teachers in this way or another.

Some people simply may not be able to love their parents.5.Seek help if you are being abused in anyway. Parents do not have a right to harm you.

A.Please remember parents are as important as friends.

B.Parents will in turn express their love to you.

C.Forgiveness is the key.

D.Here are some ways to love your parents.

E.There can be realistic reasons for this, family violence for example.

F.Anyway, spend as much time with them as you can.

G.After this, share your feelings with your parents.

    Fifteen years ago, I took a summer vacation in Lecce in southern Italy. After climbing up a hill for a panoramic(全景的) view of the blue sea, white buildings and green olive trees, I paused to catch my breath and then positioned myself to take the best photo of this panorama.

Unfortunately, just as I took out my camera, a woman approached from behind, and planted herself right in front of my view. Like me, this woman was here to stop, sigh and appreciate the view.

Patient as I was, after about 15 minutes, my camera scanning the sun and reviewing the shot I would eventually take, I grew frustrated. Was it too much to ask her to move so I could take just one picture of the landscape? Sure, I could have asked her, but something prevented me from doing so. She seemed so content in her observation. I didn’t want to mess with that.

Another 15 minutes passed and I grew bored. The woman was still there. I decided to take the photo anyway. And now when I look at it, I think her presence in the photo is what makes the image interesting. The landscape, beautiful on its own, somehow comes to life and breathes because this woman is engaging with it.

This photo, with the unique beauty that unfolded before me and that woman who “ruined” it, now hangs on a wall in my bedroom. What would she think if she knew that her figure is captured(捕捉) and frozen on some stranger’s bedroom wall? A bedroom, after all, is a very private space, in which some woman I don’t even know has been immortalized(使……永存). In some ways, she lives in my house.

Perhaps we all live in each others’ spaces. Perhaps this is what photos are for: to remind us that we all appreciate beauty, that we all share a common desire for pleasure, for connection, for something that is greater than us.

That photo is a reminder, a captured moment, an unspoken conversation between two women, separated only by a thin square of glass.

1.What happened when the author was about to take a photo?

A.Her camera stopped working.

B.A woman blocked her view.

C.Someone asked her to leave.

D.A friend approached from behind.

2.According to the author, the woman was probably___________.

A.enjoying herself

B.losing her patience

C.waiting for the sunset

D.thinking about her past

3.In the author’s opinion, what makes the photo so alive?

A.The rich color of the landscape.

B.The perfect positioning of the camera.

C.The woman’s existence in the photo.

D.The soft sunlight that summer day.

4.The photo on the bedroom wall enables the author to better understand ____________.

A.the need to be close to nature

B.the importance of private space

C.the joy of the vacation in Italy

D.the shared passion for beauty

    Cities usually have a good reason for being where they are, like a nearby port or river. People settle in these places because they are easy to get to and naturally suited to communications and trade. New York City, for example, is near a large harbour at the mouth of the Hudson River. Over 300 years its population grew gradually from 800 people to 8 million. But not all cities develop slowly over a long period of time. Boom towns grow from nothing almost overnight. In 1896, Dawson, Canada, was unmapped wilderness (荒野). But gold was discovered there in 1897, and two years later, it was one of the largest cities in the West, with a population of 30,000.

Dawson did not have any of the natural conveniences of cities like London or Paris. People went there for gold. They travelled over snow-covered mountains and sailed hundreds of miles up icy rivers. The path to Dawson was covered with thirty feet of wet snow that could fall without warming. An avalanche (雪崩) once closed the path, killing 63 people. For many who made it to Dawson, however, the rewards were worth the difficult trip. Of the first 20,000 people who dug for gold, 4,000 got rich. About 100 of these stayed rich men for the rest of their lives.

​But no matter how rich they were, Dawson was never comfortable. Necessities like food and wood were very expensive. But soon, the gold that Dawson depended on had all been found. The city was crowded with disappointed people with no interest in settling down, and when they heard there were new gold discoveries in Alaska, they left Dawson City as quickly as they had come. Today, people still come and go — to see where the Canadian gold rush happened. Tourism is now the chief industry of Dawson City — its present population is 762.

1.What attracted the early settlers to New York City?

A.Its business culture. B.Its small population.

C.Its geographical position. D.Its favourable climate.

2.What do we know about those who first dug for gold in Dawson?

A.Two-thirds of them stayed there.

B.One out of five people got rich.

C.Almost everyone gave up.

D.Half of them died.

3.What was the main reason for many people to leave Dawson?

A.They found the city too crowded.

B.They wanted to try their luck elsewhere.

C.They were unable to stand the winter.

D.They were short of food.

My First Marathon（马拉松）

A month before my first marathon, one of my ankles was injured and this meant not running for two weeks, leaving me only two weeks to train. Yet, I was determined to go ahead.

I remember back to my 7th year in school. In my first P. E. class, the teacher required us to run laps and then hit a softball. I didn't do either well. He later informed me that I was “not athletic".

The idea that I was “not athletic" stuck with me for years. When I started running in my 30s, I realized running was a battle against myself, not about competition or whether or not I was athletic. It was all about the battle against my own body and mind. A test of wills!

The night before my marathon, I dreamt that I couldn't even find the finish line. I woke up sweating and nervous, but ready to prove something to myself.

Shortly after crossing the start line, my shoe laces（鞋带）became untied. So I stopped to readjust. Not the start I wanted!

At mile 3, I passed a sign： "GO FOR IT, RUNNERS!”

By mile 17, I became out of breath and the once injured ankle hurt badly. Despite the pain, I stayed the course walking a bit and then running again.

By mile 21, I was starving!

As I approached mile 23, I could see my wife waving a sign. She is my biggest fan. She never minded the alarm clock sounding at 4 a. m. or questioned my expenses on running.

I was one of the final runners to finish. But I finished! And I got a medal. In fact, I got the same medal as the one that the guy who came in first place had.

Determined to be myself, move forward, free of shame and worldly labels（世俗标签），I can now call myself a “marathon winner".

1.A month before the marathon, the author .

A.was well trained B.felt scared

C.made up his mind to run D.lost hope

2.Why did the author mention the P. E.class in his 7th year?

A.To acknowledge the support of his teacher.

B.To amuse the readers with a funny story.

C.To show he was not talented in sports.

D.To share a precious memory.

3.What does the story mainly tell us?

A.A man owes his success to his family support.

B.A winner is one with a great effort of will.

C.Failure is the mother of success.

D.One is never too old to learn.

The big Town Hall clock was striking midnight when Frank began to cross the bridge. The dark night air was cold and a little wet, and the street lamp gave little light. Frank was anxious to get home and his footsteps rang loudly on the silent night.

When he reached the middle of the bridge, he thought he could hear someone coming near behind him. He looked back but could see no one. However , the sound continued and Frank began to walk more quickly. Then he slowed down again , thinking there was nothing to fear in a town as quiet as this.

Just then , he heard short , quick steps closely behind him. By the time he reached the other side of the bridge , he could almost feel someone at his heels. He turned round and there stood a man in a large coat. A hat was pulled down over his eyes and very little of his face could be seen.

Frank said something about the weather in an effort to be friendly. The man did not answer but asked roughly where Oakfield House was. Frank pointed to a big house in the distance and the stranger continued his way.

Then Frank wondered why the stranger had wanted to find Oakfield House at such an hour. He knew that the people who lived there were very rich. Almost without realizing what he was doing , he began following the stranger quickly.

The man was soon outside the house and Frank saw him look up at the windows. A light was still on and the man waited until it went out. When about half an hour had passed, Frank saw him climb noiselessly over the wall and heard him drop on the ground at the other side.

Paragraph 1:

Now Frank knew what the man wanted to do.
