My wallet was gone. And I could only have left it one place: the G9 bus, from which I had gotten off minutes earlier and which was now speeding to some stops. The moment of realizing it was gone was followed by mental math. How much time and money would it cost to replace the credit cards, the driver's license, the expensive lipstick ($ 55!).Two hours after I was back at my house, I heard a knock on the door. My husband answered while I sat in the dining room on the phone with a credit card company. "Does Jennifer live here?" I heard someone say. In her hand was my wallet, without a penny missing. She left before I could offer my gratitude to her.After I posted the story, I heard from her boyfriend, who identified the good citizen as Erin Ball, a 26-year-old girl working for a trade organization.Once I figured out her, I called to thank her. She said she spotted my wallet and thought that it's more dangerous to go to a stranger's house than leaving the wallet with the driver, but she still decided to take the chance. "If I were in that situation, I would want someone to try to find me," she said. Ball doesn't find her actions particularly excellent. She added, "It's not hard to do small things for people."After Ball found my wallet, she decided to post a picture of my driver's license online before going to my house, trying to see if anyone knew me. No sooner had she left my doorstep than I got emails from two neighbors who recognized my face, both offering to help me find my missing property.Ball found my house on a bitterly cold night for which I was extremely grateful. Looking back, I'm not surprised someone had wanted to help a stranger. A warm current of honesty and harmony is running through thistown.4. What do we know about the author according to paragraph 1?A. She missed the G9 bus.B. She paid for her bananas.C. She replaced the credit cards.D. She found she had left her wallet on the bus.5.

Which of the following best describes Erin Ball?A. Humorous and kind.B. Generous and demanding.C. Honest and warm-hearted.D. Caring and outgoing.CThe world's largest iceberg is floating toward South Georgia in the southernAtlantic Ocean. Scientists fear the iceberg could crash into the island and block major feeding areas for a large population of penguins and seals. If the iceberg hits the island, it could prevent the penguins and seals from reaching food supplies.The huge iceberg is named A68a. It broke away fromAntarctica's Larsen C Ice Shelf in 2017. Satellite images show the iceberg has remained in one piece. It is estimated to be about 150 kilometers long and 48 kilometers wide. It is traveling at one kilometer per hour and is on a path to hitSouth Georgiain around 30 days.This is the time of year when seals and penguins spend a lot of time caring for their young. The distance that parents have to travel to find food is crucial. That means they have to go a lot further or go around the iceberg tofind sources of food.Ecologists say an iceberg crash would also disturb materials settled on the seabed, possibly polluting the surrounding seas. As the iceberg melts, it would also release large amounts of fresh water into the ocean. This could affect krill（磷虾）populations that are a major source of food for the island's wildlife. The iceberg could remain for up to 10 years and change the area's whole ecosystem. These are globally significant populations of these species. If these species fail in this particular area, then the numbers globally are going to go down quite dramatically.Professor Geraint Tarling, an ecologist at the British Antarctic Survey, said, "The breaking off of icebergs fromAntarcticais a natural process. But the process is changing with climate change. What we're seeing with models and some observations now is that this is happening at an increasing rate. And so, this might become more of a usual thing in the future."8. Why are the scientists worried about the coming iceberg crash?A. It will bring extremely cold weather.B. It will destroy the feeding areas of the animals.C. It will put wildlife on the island at risk of starving.D. It will prevent animals from moving to other places.9. What is paragraph 2 mainly about?A. The characteristic of the iceberg.B. The importance of the iceberg.C. The traveling speed of the iceberg.D. The forming process of the iceberg.10. What damage can an iceberg crash bring according to paragraph 4?A. Using up much fresh water.B. Polluting the surrounding farms.C. Changing the world's ecosystem.D. Affecting the number of certain species.11. How does Tarling think of the breaking off of icebergs fromAntarctica?A. It may slow down in the near future.B. It may become common in the future.C. It has a great influence on the climate.D. It helps scientists conduct a sea study.DIn the world of Chinese archaeology(考古学), a sign of a dig's importance is the sight of Zhou Mingsheng at work. A field technician who has worked at archaeological sites all aroundChina. Master Zhou iscredited with the gentlest touch in his profession. Born into a farming family, he is a “national-level craftsman” with a talent for using simple tools to get relics(遗物) that wouldcrumblein other hands, says his current boss, Wang Xu, director of an archaeological site at Shuanghuaishu, a Neolithic(新石器时代的) settlement near the Yellow River in the central province of Henan.It is not beauty that attracts visitors to Shuanghuaishu. At 5,300 years old, the settlement is the work of a culture too simple to have left behind many buried treasures. The single most precious find, to date, is a finger-length sculpture of a silkworm. Nor is the setting lovely: an area surrounded by deafening insects, between a highway and two power stations. Rather, the site's importance is historical. For since the birth of Chinese archaeology in the 1920s, it has been inseparable from claims thatChinahas the oldest unbroken civilisation on Earth.Leading archaeologists say that the site has the right combination of location, age and distinctive cultural elements to be the capital of an early Chinese kingdom. That would make it a bridge betweenChina's written history and the era of the Yellow Emperor, who is said to rule over these central plains almost 5,000 years ago, though many foreign scholars doubt his existence. Chinese media call the site proof ofChina's 5,000 years of history.Foreigners complain about a lack of written records, Mr. Wang notes. Perhaps they are missing symbols that will one day be understood, for instance in patterned pottery. Outsiders “can't keep using Western standards to apply to Chinese ruins,” he argues.12. What does the underlined word “crumble” in Paragraph 1 mean?A. Break.B. Start.C. Wait.D. Shine.13. Why does Shuanghuaishu attract visitors?A. It has appealing scenery.B. It has various precious treasures.C. It is of great historical significance.D. It is easily accessible.14. What is Mr. Wang's attitude towards foreigners’ view?A. Unconcern.B. Disapproving.C. Supportive.D. Not mentioned.15. What does the passage mainly talk about?A. Chinese history amazes the world.B. Chinese archaeology catches on.C. China follows its tradition.D.Chinadigs its past.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

But a dog's life is much shorter than humans, about 12 to 15 years long, which means every dog owner has to go through the heart­breaking moment when their loving pet passes away.Why not make a clone of that dog then? This is the solution offered by a South Korean company, Sooam Biotech Research Foundation. The company has already successfully cloned at least 400 dogs, mostly for US customers, ever since it pioneered the technique in 2005. Now, Sooam Biotech has introduced its business toUKdog owners as well, offering them dogs that look just like their lost ones.To clone a dog, researchers first need to take a skin cell from a living dog or one that has just died. Meanwhile,another dog is selected to supply an egg. Researchers then replace the DNA in the egg with that from the skin cell and implant the egg into the womb (子宫) of a female dog. The egg grows into a puppy over the following two months. The whole process takes less than a day, but it comes at a shockingly high price — around ￡63,000.But if you can't afford it now, you can also save the cell in a laboratory andaccess it at a later date.However, magical as cloning might sound, there is no guarantee that the cloned dog will be a perfect copy of the original one. Just like identical twins of humans, they share the exactly same DNA but there will still be small differences between them. “The spots on a Dalmatian (斑点狗) clone will be different, for example” Insung Hwang, head of Sooam Biotech, told The Guardian.Dog owners will also have to accept the fact that personality is not “cloneable”. Apart from genes, personality is also determined by upbringing and environment, which are both random elements that cloning technologies simply cannot overcome, Professor Tom Kirkwood atNewcastle University,UK, told The Telegraph.Perhaps bringing our dogs back by cloning is not the best way to remember them after all.Kirkwood, a dogowner himself, pointed out, “An important aspect of our relationship with them is coming to terms with the pain of letting go.”4. What service does Sooam Biotech Research Foundation offer?A. Making copies of pet dogs.B. Giving pet dogs identical twinsC. Helping dogs give birth to more puppies.D.Helping dog owners love their dogs more.5. Which order is correct in the dog cloning process?a. An egg is taken from another dog.b. A skin cell is taken from the pet dog.c. The egg grows into a puppy in two months.d. The egg is placed in the womb of a female dog.e. The DNA in the egg is replaced by the DNA from the skin cell.A.a→d→b→e→c.B. a→e→b→d→cC. b→a→d→e→c.D. b→a→e→d→c.6. What can we learn about dog cloning from the passage?A. It has not been put into practice until recently.B. It is very popular among US andUKpet owners.C. It might not give the owners an exactlysame dog.D. It is very expensive and usually takes half a year to complete.7. What doesKirkwoodthink of dog cloning?A. He disagrees with it.B. He supports it.C. He is curious about it.D. He thinks it unbelievable.CDengue is a very painful illness spread by mosquitoes. In severe cases, dengue can even be deadly. Dengue is a serious disease affecting people in around 120 countries. It can cause high fevers, headaches, and severe pain. It’s caused by a virus spread by bites from mosquitoes. Therefore, dengue is more common in warm areas. Every year, roughly 390 million people get dengue, and as many as 25,000 die from it.Now scientists seem to have found a way to protect humans from dengue by first protecting mosquitoes. Dengue fever is caused by a virus. Though it may seem strange to think of it this way, the mosquitoes that spreadthe dengue virus are also infected with it. But the virus doesn’t seem to hurt the mosquitoes.Wolbachia is a kind of bacteria commonly found in many insects. In some insects, Wolbachia can keep some viruses fromduplicatingthemselves, which is how viruses grow inside a body. Wolbachia isn’t naturally found in mosquitoes. But by infecting these mosquitoes with Wolbachia, scientists can keep the mosquitoes from catching the dengue virus. Even better, the young mosquitoes coming from the eggs of the infected mosquitoes also carry Wolbachia.Researchers working with the World Mosquito Program (WMP) ran a 27-month study in Yogyakarta, Indonesia. They split a 10-square-mile area up into 24 smaller areas. In half of the areas, the scientists did nothing. In the other half, they set out containers of eggs from mosquitoes that had Wolbachia. They did this every two weeks for just 4 to 6 months.Ten months later, 80% of the mosquitoes in the treated areas carried Wolbachia. The researchers report the number of dengue cases in the treated areas was reduced by 77% and that the number of people needing hospital care for dengue dropped by 86%.Because the results of the experiment were so good, the WHO has placed Wolbachia-infected mosquito eggs in all parts of Yogyakarta and surrounding areas. The WHO says that within a year, their efforts will protect 2.5 million people against dengue and that their efforts will be turned into a program that can be repeated worldwide.8. What kind of disease is dengue?A. It is likely to cause death.B. It causes no pain but fevers.C. It happens less often in hot areas.D. It hurts both people and mosquitoes.9. The underlined word “duplicating” in paragraph 3 most probably means “________”.A. worsening the harm ofB. expanding the size ofC. increasing forces ofD. making copies of10. What can be inferred about the method from the figures listed in paragraph 5?A. Its wide use.B. Its effectiveness.C. Its complexity.D.Its easy operation.11. What’s the WHO’s attitude towards the method?A. Ambiguous.B. Positive.C. Tolerant.D. Skeptical.DWhy can friendships be hard? Because often people aren't as honest and open as they should be. Sometimes, people end up getting hurt.Most problems with friendships come up because people are just too selfish to care about the things that their friends need. They care about their own needs much more, which makes it hard for friendships to work. However, being selfish is part of human nature. A person is put together in order to take care of himself and his own needs, not necessarily those needs of other people. Even though being selfish is something that all humans are born with, it is something that everyone should guard against.The best thing to remember when you are a friend to anyone is that you need to treat your friend the same way as you'd like to be treated. This is wonderful advice for a friendship, because it is really the only way to make sure that you are giving your friend everything you would want to be given in a friendship. Whenever you have a question about how you should treat a friend, it is easy to find an answer simply by asking yourself what you would like your friend to do for you, if he or she is in your shoes.Even if you're always thinking about how you'd like to be treated, and your friends are too, there are issues that come up from time to time in each friendship, and it is important to understand how to deal with these issues so that you can build stronger and healthier friendships. Issues like friends getting boyfriends or girlfriends and not spending enough time with their friends, or even friends finding new friends and leaving old friends behind are issues that will probably come up with one or more of your friendships. It is important to know how to deal with these issues so that you can keep your friends and make new ones. No one wants to have a broken friendship.12. Why may problems with friendships appear?A. One is selfish.B. One is alone.C. One is too anxious.D. One is too busy.13. What's the first and most important thing to be other people's friend?A. Not to hurt your friends' feelings.B. To give your friends whatever you have.C. To treat your friends as fairly as possible.D. Not to think of your own needs any more.14. What is the text mainly about?A. The Meaning of FriendshipsB. The Importance of FriendshipsC. The Advantages of FriendshipsD. The Problems with Friendships15. What may follow the last paragraph of the text?A. How to make many friends.B. How to keep friends happy.C. How to treat friends correctly.D. How to solve friendship issues.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

Ice Lantern Festival: where large ice buildings and statues constructed with lights inside that make them glow.SiberianTigerPark: The park has several large caged areas where the tigers roam freely and live as they-would in their natural environment. We enter these caged areas in a specially designed van with large windows to get a look at these beautiful beasts. Live pheasants (雉) are let loose (if you pay) in order to show you the tigers' natural hunting skills.Russian Architecture: Blessed with grace and character, the city is famous for its unique, Russian-influenced architecture. Remnants (残存) from the days when Harbin wasan important stop on the Russian Manchurian Railroad, the dome-shaped structures remind people of pre-revolutionary Russia. The strong Russian flavor continues to impact the city today due to new trade and tourism betweenHarbinandRussia.TheCentral Avenue: Passers-by only street, a perfect remaining part of the busy international business activities at the turn of the 20th century. The 1.4-km long street is a worthy museum of European architectural styles, including Baroque and Byzantine facades, Jewish architectural wonders, little Russian bakeries, French fashion houses, American snack food outlets, and Japanese restaurants.Guogeli Avenue:Harbin's second biggest shopping district dotted with Russian buildings. A tram track is still preserved in the centre of the road. The street is named after Nikolay (Vasilyevich) Gogol (1809-1852); great Russian novelist, dramatist, satirist, founder of the so-called critical realism in Russian literature, best-known for his novel MERTVYE DUSHI I-II (1842, Dead Souls).Saint Sophia Church (built in 1903): The Orthodox church is a wonderful example of Russian Architecture. We only tour the outside of the church. The inside has been turned into some painters' market and is a big disappointment to all who visit it. You are welcome to venture into the church. Entrance fees are RMB20 per person.1. From where does the author look at the tigers?A. Through the windows of his house.B. In the closed areas of tigers.C. In the areas for walking.D. In their natural environment.2. Where can visitors see the most diverse styles of architecture?A. At Ice Lantern Festival.B. On the Russian Manchurian Railroad.C. On TheCentral Avenue.D. OnGuogeli Avenue.3. When walking in the city ofHarbin, what can visitors still strongly feel?A. The Russian flavor.B. The influence of Guogeli's realism.C. The damage to Saint Sophia Church.D. The mixture of American and Japanese cultures.BNostalgia (怀旧) has become increasingly common in our current climate of accelerated, unexpected change. More and more Americans are turning back with longing towhat feels like simpler, sweeter times. They collect cassette tapes, manual typewriters even decades-old video games.Is it a mistake to get too obsessed with the past? Some psychologists warn that too much devotion to the so-called good old days is an escape from reality; it can indicate loneliness or that a person is having a difficult time coping in the present. Psychologist Stephanie Coontz argues that nostalgia distracts us from addressing the problems of modern life and contribute to anxiety, depression , insomnia etc.But new studies suggest that a modest dose of nostalgia is not only harmless, but actually beneficial. They suggest it helps strengthen our sense of identity and makes us feel more optimistic and inspired. It is also a tool for self — discovery and memories are a psychological immune response that is triggered when you want to take a break from negativity. Interestingly, those happy memories can be particularly beneficial both to kids in their teens and to society's elders. Recalling our childhood reminds us of “the times when we were accepted and loved unconditionally," says Krystine Batcho, a psychologist. "That is such a powerfully comforting phenomenon, knowing that there was a time in life when we didn't have to earn our love." Nostalgia can transform even the most ordinary past into legends which warms the heart and the body. Let's not forget that nostalgia has been a source of inspiration to innumerable American writers. Mark Twain recalled his boyhood, writing, "after all these years, I can picture that old time to myself now, just as it was then：The white town drowsing in the sunshine of a summer's morning."So go ahead, daydream a little about your best childhood friend, your first car, a long - gone family pct. As Dr. Sedikidessays，"Nostalgia is ly central to human experience. "But at the same time, keep these words of wisdom from the great inventor Charles Kettering in mind as well："You can't have a better tomorrow if you are thinkingabout yesterday all the time. "34. What did some psychologists in paragraph 2 probably agree?A. Nostalgia will cause some mental problems.B. Nostalgia makes us devoted to the good old days.C. Nostalgia shows you are trying to get rid of loneliness.D. Nostalgia helps us cope with the difficult time we are going through.5. There are many benefits of nostalgia except ________A. It can enable us to know ourselves better.B. It can bring us some comfort when we recall.C. We are likely to gain attention if we recall the happy childhood.D. We can sometimes break away from negativity with happy memories.6. What will be talked about in the following paragraph?A. The bad influence of too much devotion to nostalgia.B. The reasons why we should avoid nostalgia.C. The bad memories that always stick around you.D. The great changes nostalgia will bring to you.7. What's the best title of the passage?A. We all have a soft spot for nostalgia.B. Nostalgia is actually good for you.C. Don't be carried away by nostalgia.D. There are many times when we like to recall.CDragon boating is a team sport that has its root in ancient China. The boats are decorated with a dragon head and tail. In recent years cancer survivor groups have got involved in the sport to help make friends and help rebuild their lives.On a recent Saturday morning, a group of 20 women were on a boat in the Anacostia River in Washington DC. They moved their paddles(船桨)in rhythm to the call of a coach. The women belong to the dragon boat team GoPink! DC, which trains weekly. It also races against other breast cancer survivor teams in dragon boat festivals. As a result, GoPink! DC won medals in this Washington dragon boat festival.Lydia Collins joined five years ago after finding out she had breast cancer. “I was diagnosed with breast cancer.I was demoralized because of my illness - I lost all interest in life and wouldn't even get out of bed to eat. But now I love the team spirit. I just love everything about it. It is like a floating support group on the water.”The paddles are breast cancer survivors and their supporters. Annette Rothemel helped establish(建立)the group in 2006. She is a researcher with the National Institutes of Health as well as a breast cancer survivor. “It is sort of an easy entry sport because on the same boat people at different levels can be doing the same sport.” But Ms Rothemel saysdragon boating can be physically demanding, especially for someone who is sick and getting treatment for cancer.“It’s hard but I think you have to challenge yourself in life. This is something I look forward to. I get to be out here with my sisters and supporters that understand what I’m going through and help motivate me. So it makes me stronger and it makes me feel better,” another cancer survivor Rhonda Hartzel said.Annette Rothemel says the cancer survivors feel a sense of sisterhood and share good times when they paddle together. She says both feelings are treasured by the team.8. What do the underline wordsdemoralizedIn para.3 probably mean?A. depressedB. anxiousC. astonishedD. awkward9. What can we know about Lydia Collims from the text?A. she helps establish Go Pink !DCB. she tries to find a cure for the cancerC. she benefits from the dragon boat raceD. she gives up hope because of her illness10. How can the dragon boat race help the cancer survivorsA. forget their tough experiencesB. recover physically and mentallyC. get rid of the pains of their cancerD. enjoy their rest life without sufferings11. What does the text tell us about Annette Rothemel?A. she is an expert in studying the cause of the cancerB. she helps the cancer survivors in financial difficultiesC. she believes there is a healthful result from the dragon boat raceD. she thinks it unwise for the patient to join in the dragon boat raceDA team of researchers from several institutions in the UK and one in Estonia has created a type of buoy（浮标）that has proven to be effective at frightening seabirds, thus preventing them from getting caught in gillnets—a type of vertical fishing net that is made of a material that makes it nearly invisible underwater.Every year, hundreds of thousands of seabirds die when they get caught in gillnets. Some estimates suggest that up to a half-million birds are caught in them each year. Over the years, researchers have created devices（装置）to prevent the birds from trying to catch fish near or in gillnets, but those didn't work well.To find a way that would work for all seabirds, the researchers first studied seabirds in a general sense, looking to find things that they would avoid. They noted that seabirds avoided eye contact with other creatures. Then the researchers came up with a simple idea—they put a small pole to a regular buoy and then attached a pair of googly eyes（金鱼眼）to the top of it. They made the eyes big enough so that even birds with poor eyesight, such as geese, would see them. Adding to the effectiveness of the device, waves made the eyes move back and forth. And the wind made the buoy spin very slowly, making sure that birds from every direction would get a good look at the eyes.To test their idea, the researchers selected several sites near gillnets and counted how many birds approached and how many attempted to catch fish near the nets. They then set up their googly-eyed buoys and once again counted birds. Over the course of 62 days, they found the number of birds that tried to catch fish near the gillnets dropped by approximately 25% for a distance of up to 50 meters. They also found that the birds were less likely to fish near where the buoys had been for up to three weeks after they had been removed.12. What is the function of paragraph 2?A. Introducing a new topic to discuss.B. Providing background information.C. Summarizing the previous paragraph.D. Pointing out the main idea of the text.13. Why did the researchers make the googly eyes big?A. To ensure all the seabirds can see them.B. To clearly observe seabirds' eye contact.C. To allow them to survive the strong wind.D. To effectively identify the right direction.14. What does the researchers' test result mainly suggest?A. The new device still needs improvingB. Gillnets are a death valley for seabirds.C. Seabirds hardly catch fish near the nets.D. The googly-eyed buoy proves effective.15. What is the text mainly about?A. A group of researchers interested in seabirds.B. A way to help seabirds catch fish effectively.C. A device keeping seabirds safe from gillnets.D. A googly-eyed buoy guiding seabirds to hunt.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
