新高二(模拟上海中学入学摸底卷)第I卷(选择题)一、语法填空(每小题1分,共10分)Buy a Cup of Coffee for a StrangerCoffee has developed rapidly and soon become an essential friend and companion for many people.(1) you first meet her, you'll drink it for a while, feeling refreshed. Slowly, the deeper you go, the more you'll become addicted to it, attracted by her unique smell. You can't help but (2) (follow) her, and you always think coffee has a story.Coffee can be traced back to about the 10th century AD. It was (3) the 16th century that coffee was introduced to Europe. The way that coffee is grown and made has been refined by the Arabs, and modem coffee is all beverages (饮料).How about buying a cup of coffee for someone you'll never meet? It may sound like the latest trend in the coffee culture, but a suspended coffee is (4) (heartwarming) than a popular latte. The tradition born in a cafe in the southern Italian city of Naples is to buy a cup or two of coffee in advance for (5) who need it later in the day. A customer-in-need can then later ask if there is a suspended coffee available and have a hot drink(6) having to pay for it.It may be hard to imagine that this idea has become an internet fashion, with countless coffee shops in Europe and North America (7) (participate) in the movement. The Facebook page alone has more than 28, 000 “likes". The tradition of suspended coffee is a long-standing one in Italy (8) increased in popularity after the Second World War. Agence France-Presse reported last week the practice was starting to be popular in other European countries (9) (hit) hard economically. More than 150 cafes in Bulgaria were taking part. At the very cafes customers can ask. whether there are any suspended coffees available, and if so, they (10) (supply) with a beverage, thanks to the kindness of a stranger.二、完形填空(每小题1分,共15分)Color Can greatly Affect Human Emotion and BehaviorThere’s been a lot written about color ps ychology but what we do know is that color can greatly affect human emotion and behavior. A lot of us already know that colors can suggest a mood or attitude, but do you know that color is a 11 that can persuade us to buy things? According to some research, color can be up to 85 percent of the reason why we 12 to purchase something. Smart marketers know: Color 13 !Yes, you know, right colors make products better. Colors 14 how we feel about the food we eat. 15 , orange juice with enhanced orange color was preferred over naturally colored orange juice and was thought to be sweeter.In the case of 16 , color also plays a role. Have you ever noticed that pink is often used as the color of face creams? That’s for a good reason. In a re search study, some women were given pink and white face creams, which were 17 except for their color. One hundred percent of the women said that the pink face creams were more effective and milder on sensitive skin.18 , “more colorful, more personalized” is also accepted by most producers. It’s true that we need not only good quality products, but personalized ones. This urges manufacturers to make their products more and more “colorful”.Take M&M’s Milk Chocolate Candies for example. Having a packet of M&M’s candies in 19 , choosing which one to eat first according to the colors-- many of us probably have had such experience. A variety of colors is the 20 of the classic candies. Now they have come with even more custom colors that will be sure to “21 in your mouth, not in your hand!” Gold, silver, pink and many other colors are available to choose from. Eating such candies must be 22 “sweet” experience.Another successful color marketing example is Apple’s iPhone. Does Apple have23 communication technology?

Each word can only be used once. Note that there is one word more than you need.We often use the terms “worry,” “stress” and “anxiety” interchangeably, but they aren’t the same. Each has unique 26.and features. Identifying which one is 27.us will help us better address it. Registered psychologist Kristin Buhr, a director at the North Shore Stress & Anxiety Clinic in North Vancouver and co-author of The Worry Workbook, 28.the differences.Worry is a negative thought you have about an uncertainty in life. Worries tend to focus on the assumption that something negative will come from future events or from the results of 29.that happened in the past.Stress involves your reaction to pressures placed on you. You feel overwhelmed because life is demanding too much of your limited time, energy or some other personal resource. While worries are thoughts, stress is a feeling.Anxiety is your mental and physiological response to a perceived threat. It’s like the body’s smoke detector—it 30.danger and signals your body to run to deal with it. While worry takesplace only in the mind, anxiety can have physical effects, like speeding up your pulse rate. Worry, however, 31.anxiety when your mind perceives imagined uncertainties as real threats.While worry, stress and anxiety are normal, intense and 32.anxiety can become a problem. You might have a behavioral 33.if, for instance, you have regular sleep issues or you’re skipping out on your accustomed activities. Excessive anxiety can be focused on a fear of something specific, like social gatherings (known as social anxiety) or a host of experiences (known as generalized anxiety disorder).The best way to avoid risk is getting it all out. Telling a friend or family member what’s worrying you, or even saying it aloud to yourself or writing it down, can allow you to see the 34.. “It’s a little easier to challenge worries—to recognize that if there is a negative outcome. It’s more of a struggle than a horror—when your worries are on paper or said out loud, rather than 35.around in your head,” says Buhr.四、阅读选择(每小题2分,共20分)AWhen I was three, my parents took me to have an operation in India, which stopped my eyesight from deteriorating(恶化). Several years later we moved to Pakistan, where I received 12 operations within one year and went completely blind. Later, I realized that the doctors used me as an experiment.I met my husband when he came over from India to study. I wanted to go to India to marry him, but it was almost impossible to emigrate. I made a crazy plan to cross the borders of several countries to get to India. I was arrested in the first country I escaped to. Back in Pakistan, I lost my job and was asked to sign a “never-to-escape” promise. Instead, when I got home, I made a cup of coffee and decided to make a formal application for emigration.The chance was slim , and people who applied to go to India found it hard to find a job in Pakistan while they were waiting. In the end, my husband managed to smooth the way for my emigration. We got married and had children. But after nine years, he died of brain cancer. I was helpless for a while, and then I learned to face reality optimistically. He taught us happiness came from inside us.Six years ago, I brought home a dog called Moritz from the seeing-eye dog centre. He was short with long ears. No one liked him because of his pathetic(可怜的)appearance. We were almost always together. Moritz could not leave me for even one minute. Now when I walk downthe street, not like before, people will come up and say, “What a good seeing-eye dog!”, and have a little chat with me as a normal creature.I’m now working for the Association of the Blind and I have many good friends, and a special friend in Hamburg. It is a wonderful feeling to speak freely with someone I can’t see, to trust one another.36.The author went blind just because _______.A.she was born completely blindB.she received an operation in IndiaC.her parents didn’t pay attention to her illnessD.she was unluckily put to the test37.What does the underlined part in Paragraph 2 mean?A.It was full of hope to unite with her husband.B.Emigrating to India was never easy at that time.C.She was very thin and weak at that hard time.D.There was little chance to find a job in India.38.When the author walked down the street before, people may _________.A.look down upon her and view her as a poor beingB.chat with her with great warmthC.criticize how ugly her dog lookedD.respect her for her independence39.From the text, we learn the author is ________.A.a burden not only for her family but also for the societyB.a kind-hearted lady protecting wretched petsC.not an obedient citizenD.a determined and optimistic personBThere are many places to go on safari (观赏野生动物) in Africa, but riding a horse through the flooded waters of Botswana's Okavango Delta must rank as one of the world's most exciting wildlife journeys.Several safari camps operate as the base for this adventure, providing unique rides twice aday to explore deep into the delta. The camps have excellent horses, professional guides and lots of support workers. They have a reputation for providing a great riding experience.The morning ride, when the guides take you to beautiful, shallow lakes full of water lilies, tends to be more active. It is unlike any other riding experience. With rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face, it is truly exciting. You are very likely to come across large wild animals, too. On horseback it is possible to get quite close to elephants, giraffes and many other animals. The sense of excitement and tension levels rise suddenly though, as does your heart rate, as you move closer to them.In the evening, rides are usually at a more relaxed and unhurried pace, with golden light streaming across the grassy delta and the animals coming out to eat and drink. Sedate though they are, rides at this time of day are still very impressive. As the sun's rays pass through the dust kicked up by the horses, the romance of Africa comes to life.Back at the camp you can kick off your boots and enjoy excellent food and wine. Looking back on your day, you will find it hard to deny that a horseback safari is as close as you will ever come to answering the call of the wild.40.What is the purpose of the text?A.To warn B.To entertain C.To introduce D.To educate 41.What does the author find most exciting about a horseback safari?A.Seeing and feeling the real African life.B.Enjoying good food and wine at the camp.C.Hunting large animals just as our ancestors did.D.Being part of the scene and getting close to animals.42.The author introduces the riding experience in the Okavango Delta mainly by ________. A.following space order B.following time orderC.making classifications D.giving examplesCJENISON PUBLIC SCHOOLSJenison International Academy is excited to offer online, nonessential courses to international students.

Cetaceans arc generally the oldest living mammals, and some cetaceans have reached their 200th birthday. Their size means their bodies contain far more cells than the human body. (46)“If you have more cells, that means that one of those cells has an increased risk of becoming cancerous." says Daniela Tejada-Martinez at the Austral University of Chile. "So, if you are big or live longer, you have thousands and millions of cells that could become harmful."(47) .“There's a joke that whales should be born with cancer and not even able to exist becau se they're just too big," says Vincent Lynch at the University at Buffalo, New York, lie says there is a super trivial explanation for how whales can exist. "They just evolved better cancer protectionmechanisms," he says. (48) .Now, Tejada-Martinez and her colleagues have studied the evolution of 1077 tumor suppressor (肿瘤抑制)genes (TSGs). In all, they compared the evolution of the genes in 15 mammalian species, including seven cetacean species. Genes regulating DNA damage, tumor spread and the immune system were positively selected among the cetaceans. (49) "It's not like we're gonna be taking whale genes and putting them into humans and making humans cancer resistant," says Lynch. "But if you can find the genes that play a role in tumor suppression in other animals, and if you can figure out what they're doing, maybe you can make a drug that can be used to treat people."六、概要写作(每小题10分,共10分)50. Directions: Read the following passage. Summarize the main idea and the main point(s)of the passage in no more than 60 words. Use your own words as far as possible.Docs Kilimanjaro Still Have Its Beauty?Kilimanjaro is a watershed (分水岭)between Tanzania and Kenya. It is a volcano and a snowy mountain. Surrounded by mountain forests, Kilimanjaro is home to numerous mammals, some of which are endangered. Kilimanjaro was established as a national park in 1968 and was added to the World Heritage List in 1981. In the Tanzanians5 mind, Kilimanjaro is not just a bright mountain, and it is also an interesting mountain. Kilimanjaro is a world-famous tourist resort with the world's explorers and mountain enthusiasts gathering there.Every year about 40.000 people attempt to climb Kilimanjaro, the highest mountain in Africa. They bring with them lots of waste. The crowds might damage the beauty of the place. The glaciers are disappearing, changing the face of Kilimanjaro. Hearing these stories, I'm wondering about the place - other destinations arc described as purer natural experiences.However, I soon discover that much has changed since the days of disturbing reports of camps among tons of rubbish. T find a clean mountain, with toilets at camps and along the paths. The environmental challenges are significant but the efforts made by the Tanzania National Park Authority seem to be paying off.The best of a Kilimanjaro experience, in my opinion, isn't reaching the top. Mountains are regarded as spiritual places by many cultures. This view is especially evident on Kilimanjaro as climbers go through five ecosystems in the space of a few kilometers. At the base is a rainforest. Itends suddenly at 3, 000 meters, giving way to lands of low growing plants. Further up, the weather changes — low clouds envelope the mountainsides covered with thick grass. I count twelve shades of green from where I stand. Above 4, 000 meters is the highland desert: gravel (砾石),stones and rocks. Finally, you climb into an arctic-like zone with permanent snow and the glaciers that may soon disappear.Does Kilimanjaro deserve its reputation as a crowded mountain with lines of tourists ruining the atmosphere of peace? I found the opposite to be true.七、翻译(每小题3分,共12分)Directions: Translate the following sentences into English, using the words given in the brackets.51. 90%的人都无法拒绝这样的一种善意。
