AWhen you’re on the go（四处奔走）, your best friend and resource（资源） can be your phone. In the age of smart phones, apps are like guiding stars （指路明灯）: They can point you in the right direction for a hotel, list expenses（花费）, send postcards, and much more. When used together, these apps can be the basic travel tool, placing a wealth of（很多的） information at your fingertips（指尖） no matter where you are on the planet（星球）. U.S. News Travel has picked the essential（重要的） travel apps, known for their utility（实用性）and reliability（可靠性）. Best of all, they cost absolutely（绝对地） nothing.Trip ItYour Personal Travel Agent（代理人）Be your own travel agent and plan every detail（细节） of your trip-- from car rental（租赁） to accommodating（住宿的） restaurants-- with Trip It.

Goby has the answer. This app pinpoints（准确地指出）the neighborhood （附近的）hot spots（热闹的地区）(including museums, hotels, eateries（餐馆）, and more) in yourneighborhood. But its true value（价值）comes in finding nearby events（大事件）. You'll discover concerts, plays, and more right around the corner.21.What is the advantage of using travel apps picked by the U.S. News Travel?A. They cannot solve any problem you come across.B. They increase（增加） your travel budget（预算）.C. They exercise your fingertips.D.

In a medicine（医学）magazine.C. On a popular website.D. In a business report（商业报告）.BEarly in the 16th century men were trying to reach（到达） Asia by traveling west from Europe（欧洲）. In order to find Asia they had to find a way past South America（南美洲）. The man who finally found the way from the Atlantic Ocean（大西洋） to the Pacific（太平洋） was Ferdinand Magellan (麦哲伦). Magellan sailed from Seville in August, 1519 with 5 ships and about 280 men. Fourteen months later, after spending（度过） the cold winter on the coast of Patagonia, he discovered（发现） the channel（河道） which is now called Magellan Strait (海峡). In November, 1520, after many months of dangers from rocks and storms, the 3 remaining（剩下的） ships entered the ocean on the other side of South America. They then continued（继续）, hoping to reach Asia. But they did not see any land until they reached the islands off the coast of Asia. Before they arrived at these islands, later known as thePhilippines (菲律宾), men were dying of starvation (饥饿). While they were staying in the Philippines, Magellan was killed in battle. The remaining officers then had to get back to Spain. They decided to sail round Africa. After many difficulties, one ship with eighteen men sailed into Seville three years after leaving. They were all that remained of Magellan’s exploration. However, their achievement（成就） was great. They were the first men to sail round the world.24.T he purpose of Magellan’s ex ploration was to ________.A. find a seaway（海路） from the Atlantic to the Pacific.B. sail round the world.C. carry men to Philippines.D. make a voyage to Asia.25. Which of the following is NOT mentioned in the passage concerning（与...有关） the exploration?A. Cold winter in Patagonia.B. Lack of equipment（缺乏装备）.C. The death of Magellan.D. Dangers from rocks and storms.26. The number of the ships lost on the WHOLE exploration was ________.A. twoB. threeC. fourD. five27. The best title for this passage is ________.A. The First Exploration to Sail round the WorldB. The Most Dangerous ExplorationC. The Discovery of the PhilippinesD. The Discovery of Magellan’s StraitCHave you ever found yourself in this situation（情形）: You hear a songyou used to sing when you were a child –a bit of nostalgia(怀旧) or “blast （冲击波）from the past,” as we say. But it is not a distant（遥远的）childhood memory（童年回忆）. The words（歌词） come back to you as clearly as when you sang them all those years ago.Researchers at the University of Edinburgh studied the relationship between music and remembering a foreign language. They found that remembering words in a song was the best way to remember even one of the most difficult languages.Here is what they did. Researchers took 60 adults（成年人） and randomly （随机地） divided（划分） them into three groups of 20. Then they gave the groups three different types of “listen-and-repeat（听及重复）” learning conditions. Researchers had one group simply speak the words. They had the second group speak the words to a rhythm（伴着节奏）. And they asked the third group to sing the words.All three groups studied words from the Hungarian（匈牙利的） language for 15 minutes. Then they took part in a series of（一系列的） language tests （测试） to see what they remembered.Why Hungarian, you ask? Researchers said they chose Hungarian because not many people know the language. It does not share any roots（根系） with Germanic（德国的） or Romance（罗马的） languages, such as Italian or Spanish. After the tests were over, the singers came out（出现） on top. The people who learned these new Hungarian words by singing them showed a higher overall （全面的） performance（表现）. They did the best in most of the tests. They also performed two times better than those who simply（仅仅） learned the words by speaking them.Dr. Katie Overy says singing could lead to new ways to learn a foreign language. The brain likes to remember things when they are contained（包含） in a catchy（易记的） 3, or memorable（值得纪念的） 4, tune（曲调） 5.Dr. Ludke said the findings could help those who struggle（挣扎） to learn foreign languages. On the University of Edinburgh’s website Dr. Ludke writes, “This study provides the first experimental（实验的） evidence that a listen-and-repeat singing method can support foreign language learning, and opens the door for future research in this area（领域）.”28. The “song” mentioned in the first paragraph is intended to__________.A. recall（回忆） the pastB. attract the readersC. introduce（引进） the topicD. compare the childhood with the present29. According to the passage which language doesn’t share the same root withGermanic or Romance languages?A. Hungarian.B. Spanish.C. Italian.D. English.30. Based on the last two paragraphs, we can conclude（总结） that __________.A. singing is not the best way to learn a language.B. the brain probably works best when the foreign language learners sing the words.C. a listen-repeat method is very complex（复杂的） for any language learner.D. Dr. Katie Overy and Dr. Ludke disagree（不同意） with each other.31. In which situation can the finding（发现） of the research be applied （应用）?A. A mother is going to teach her baby how to speak.B. A child is going to have his first music lesson.C. A student is going to learn a new English song.D. An American is going to learn some Chinese.DThe average（平均） American child spends three to five hours a day watching TV. In 1961, the average child began to watch television at age three, however, today it is nine months. Yet, most parents think that television has a bad influence（影响） on their children. For example, in the early 1970s, my parents believed that my bad eyesight（视力） was the result of sitting too close to the screen（屏幕）, and they therefore made my stay at least six feet（英尺） from it. Today, most people have no such worry, but many new ridiculous （荒谬的）sayings have appeared:* TV makes kids stupid（愚蠢的）. Many children watch more educational（教育性的） programs（节目） when they are pre-schoolers（学龄前儿童）. When they grow up, they can read more books and have much better ideas to solve difficult problems than other children.* TV makes kids violent（暴力的）. The real story is not so simple. Hundreds of studies show that watching violence on TV makes children more aggressive （好斗的）. But a study of over 5000 children also finds that some positive programs make children kinder. The problem is that kids are increasingly （越来越） watching shows with violence instead of those suitable（合适的）for their age.* Sitting around watching TV makes kids overweight（超重）. An experiment finds that when children watch less television, they do lose extra（额外的） weight; however, reducing their television time does not make them more active. The real problem lies in（在于） snacking, a widespread（广泛传播的） habit for kids, and junk food（垃圾食品） advertisements.* TV helps kids get to sleep. The opposite（相反的） is true. The more television children watch, the more likely they are to have irregular（不规律的） sleep and nap （小睡）patterns. Allowing kids to watch television is part of the problem, not the solution.32 . Which one is the advantage of educational TV programs?A. They will make children solve difficult problems better than others.B. They will improve children’s ability（能力）to get along with others.C. They are likely to make children more aggressive.D. They will make sure of children’s success in the future.33.Why are children spending much time watching TV likely to be fat?A. Watching TV makes children lazy（懒散的）and inactive（不积极的）.B. Children are attracted by the advertisement on TV.C. Watching TV doesn’t burn up（燃烧）as much fat as doing sports.D. Children like to snack while watching TV.34.What influence does watching TV have on a child’s sleep?A. Children are likely to sleep deeper after watching TV.B. Children’s sleep time will be greatly increased（增加）.C. It will make children form a bad habit（习惯）of sleeping.D. It will make children sleep easier.35.What is the purpose of this text?A. To reduce（减少）people’s knowledge of watching TV.B. To inform（告知）parents of the advantages（优点）of watching TV.C. To explain the bad influences that watching TV has on children.D. To correct parents’wrong ideas of television’s effect on children.第二节（共5小题；每小题2分，满分10 分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

Since then，it has become a familiar term for a person who spends a lot of time sitting，and little time exercising. Although there does not seem to be any particular reasonwhy the term“couch potato”is used rather than“couch tomato”， a person may become a “couch potato ”because living this way is said to make you round likea potato. The term is also said to have something to do with the connection of potatoes with high-calorie(卡路里)food like potato chips.People now would say“couch potato” whenever they talk about overweight andobesity( 肥胖 ) ．Indeed, “couch potatoes ” are believ ed to risk heart disease ，which can be avoided by regular exercise.It is true that technology and modern life in general makes us sick ， fat ， lazy and physically/mentally soft. The more time people spend using technology ，particularly televisions and computers ， the less time they will spend being physically active.“Couch potato ” kids are a particular concern. Media reports repeatedly claim that children today are fatter than their elder generations ， but less athletically skilled ， less interested in physical activity and more addicted( 上瘾的 )to “junk food ” and technology such as television and computers. The message is clear ：today's children are fat because they are lazy and eat too much. Moreover ， because technology is becoming more sophisticated( 复杂的 ) ， children are less able to resist( 抵挡，忍得住 )technology's attraction ， and are more likely to spend more time using technology ，less time doing physical activity and，therefore ，more likely to be fat.25. The first paragraph is mainly talking about ．A．why “couch potato ” is use d as a term for a personB．when “couch potato ” is used as a term for a personC．how “couch potato ” is different from “couch tomato ”D． what kind of person looks like a potato26.

It is fun, healthyand good for the environment. Maybe that ’s why there are 1.4 billion bicycles and only 400 million c ars on roads worldwide today.

Stopping and getting off a bike is easier than stopping andgetting out of your car. You can bike to work and benefit from the enjoyable exercise without polluting the environment.

As time went on， other Chinese people came to this area and Lime house began to b e known as “Chinatown”． At the start of the 20th century ，there were just 545 Chinese people in Britain. However， this situation changed greatly after the Second World War. At this time ，many farmers in Hong Kong lost their jobs ， and decided to move to London. In the 1950s，a small Chinese restaurant opened in central London. Many British people visited it and said that Chinese food was wonderful. Suddenly ，Chinese restaurants started opening in every part of the city. Instead of too little work ，the new Chinese immigrants( 移民 ) now found that they had too much. Most of the new immigrants enjoyed their life and the chances they were offered. Many asked their friends and relatives to join them from their hometowns，and a lot of families were reunited again at this time.As time went by ，London’s Chinese community became more and more successful.The sons and daughters of the first restaurant workers ， encouraged by their parents ，studied very hard at school and university. And most got highly- paid jobs. As a result ， increasing numbers of Chinese families left Chinatown and moved to t he more expensive places. Chinatown ， however ， is still as lively as ever ，and a must- see for every visitor to London.33． What does the author mean by the underlined sentence in Paragraph 1?A． Lime house was infl uenced by World War Ⅱ.B． The number of Chinese people in Britain increased after the war.C． Many Hong Kong farmers lost their jobs because of the war.D． The new immigrants found it hard to find jobs during the war.34． Which of the following statements is NOT true?A． Before the 20th century ，“ Chinatown” in London was still very small.B． In the 1950s ， Chinese food became quite popular in Britain.C． Most of the new immigrants could find a job in the 1950s.D． With the help of the British government ， Chinatown was very successful.35． According to the passage ， now most of the Chinese living in London .A． are clever B ．work long hoursC．have highly-paid jobs D ． live an unhappy life第二节（共 5 小题，每题 2 分，满分10 分）依据短文内容，从短文后的7 个选项中为每空选出能填入空白处的最正确选项，选项中有两项为剩余选项。

AAs the saying goes, “Without music, life would be a mistake.” Music is very important in our lives and here are four of the greatest musicians in history.Ludwig van Beethoven(1770-1827)Born in Bonn, Germany, Beethoven never held an official position in Vienna. He supported himself by giving concerts, teaching piano, and the sale of his compositions (作曲). The last 30 years of Beethoven’s life were filled with a lot of hard times, the first of which was his deafness. Beethoven’s music greatly influenced the next generation of musicians.Johann Sebastian Bach(1685-1750)Bach, “the father of modern music”, was born in Eisenach, Germany. His parents died when he was nine years old, and in 1695 he went to live with his brother Johann Christoph, who was an organist (风琴手) in Ohrdruf. He stayed there until 1700. Seven years later, he moved back to Weimar, where he served as court (宫廷) organist for nine years. His music greatly influenced classical music.Frederic Chopin(1810-1849)Chopin was born in Zelazowa Wola, Poland. He showed a talent for the piano at a very young age. Chopin began composing when he was still a child, but some of his early works have been lost. He gave his first public concert in 1818. Chopin was considered as the leading musician of his time.Franz Schubert(1797-1828)Schubert was born and died in Vienna. Unlike most of his predecessors (前辈), Schubert was not a great performer. He never had much money but he was very productive. He wrote his first masterpiece when he was only sixteen. However, he died young, before his talents were even known.21. Where was Beethoven born?A. In Vienna.B. In America.C. In Germany.D. In Poland.22. Who is called “the father of modern music”?A. Bach.B. Beethoven.C. Schubert.D. Chopin.23. When did Chopin give his first public concert?A. In 1707.B. In 1810.C. In 1818.D. In 1828.24. What do we know about the four musicians?A. They all lived a hard life at their old age.B. They were all talented musicians.C. They were all born in Germany.D. They all served as a court organist.BWhen I was nine years old, I loved to go fishing with my dad. But the only thing that wasn’t very fun about it was that he could catch many fish while I couldn’t catch anything. I usually got pretty upset and kept asking him why. He always answered, “Son, if you want to catch a fish, you have to think like a fish.” I remember being even more upset then because “I’m not a fish!” I didn’t know how to think like a fish. Besides, I reasoned, “How could what I think influence what a fish does?”As I got a little older I began to understand what my dad really meant. So, I read some books on fish. And I even joined the local fishing club and started attending the monthly meetings. I learned that a fish is a cold-blooded animal and therefore is very sensitive (敏感的) to water temperature. That is why fish prefer shallow water to deep water—the former is warmer. Besides, water is usually warmer in direct sunlight than in the shade. Yet, fish don’t have any eyelids (眼皮) and the sun hurts their eyes. The more I understood fish, the more I became effective in finding and catching them.When I grew up and entered the business world, I remember hearing my first boss say, “We all need to think like sales people.” But it didn’t completely make sense.My dad never once said, “If you want to catch a fish you need to think like a fisherman.” What he said was, “You need to think like a fish.” Years later, with great efforts to promote long-term services to people much older and richer than me, I gradually learned what we all need was to think more like customers. It is not an easy job.I will show you how in the following chapters.25.Why was the author upset in fishing trips when he was nine?A. Because he could not catch any fish.B. Because his father was not patient with him.C. Because his father did not teach him fishing.D. Because he could not influence a fish as his father did.26. What did the author’s father really mean by saying “think like a fish”?A. To read books about fish.B. To learn fishing by himself.C. To study more about fish.D. To understand what fish think.27. In what kind of area can fish most likely be found according to the author?A. In deep water on sunny days.B. In deep water on cloudy days.C. In shallow water under sunlight.D. In shallow water under waterside trees.28. What did the author find after entering the business world?A. His father’s fishing advice was inspiring.B. It was easy to think like a customer.C. His first boss’ sales ideas made sense.D. It was difficult to sell services to poor people.CCan ducks help solve the problem of locust (蝗虫)? That is a question being asked in Southern Asia. Like the region of East Africa, the nation of Pakistan is trying to keep masses of locusts from eating the country’s cro ps.But while the insect invasion（入侵）in Africa has been blamed on weather, experts say the one in Pakistan is a side effect of a civil war in the Middle Eastern country of Yemen. Because of that war, officials haven’t been able to do enough pest（害虫）control to keep Yemen’s locust population from growing, so the insects obviously multiplied and made their way northeast eventually landing on P a k i s t a n.Locusts don’t directly attack people. They threaten us by eating our crops. And so many of these insects in su ch large numbers can destroy regional food supplies. That’s why Pakistan declared a state of emergency early this month, saying it was dealing with the highest number of locusts in more than 20 years. So what can be done about it? Some experts say pesticides（杀虫剂）are needed to kill masses of these insects, but there’s another idea being considered in China. It may send ducks to Pakistan ― as many as 100,000 of them ― to fight the locusts by eating them. An expert interviewed by the Bloomberg media company says one duck can eat more than 200 locusts per day, and China has reportedly used ducks to successfully solve a locust problem in the past. But not everyone is on board with this. A member of China’s delegation (代表团) to Pakistan says there’s not enough water in Pakistan’s hot dry climate to keep the ducks going. Whatever methods are used to control locusts in Asia, the situation in Africa is getting more hopeless by the day.29. According to paragraph 2, what caused the locust outbreak in Pakistan？A. There are no natural enemies to eat locusts.B. The civil war of Yemen affected pest control.C. The government of Yemen didn't do any pest control.D. The weather in Pakistan caused the increase of locusts.30. What harmful effect will masses of locusts bring about?A. Destroying crops.B. Changing the weather.C. Tensing international relations.D. Directly threatening human security.31. Which of the following can replace the underlined phrase in paragraph 3?A. Asks forB. Relies onC.Thinks aboutD. Agrees onDOne of the most popular street food found in China is no doubt the barbecue (烧烤). A new series, called Chinese Barbecue, tells the story of this popular food cooked over hot coals on just about every street corner in cities and towns acr oss the country. Barbecued meat is an important part of people’s nightlife.Shown on June 20, the series has had more than 80 million clicks on the video site . To find the most popular barbecue stalls (摊位), the production team traveled to more than 500 locations in 30 cities across the country. Some viewers compare Chinese Barbecue to Midnight Diner, a Japanese TV series telling stories from late-night informal Japanese bars.“I’m happy to hear this comparison because Midnight Diner is a good program, and we share the same topic ― night food,” Chinese Barbecue’s director Chen Yingjie said. “However, in terms of the tone（气氛，情调）, they are quite different.” He said that Midnight Diner focused more on food itself, though there was some conversation while people were eating. In contrast, the night food scene of Chinese people means joy and a more lively spirit. People eating these barbecue snacks develop a feeling of connection, which can be a cure for loneliness.The barbecue, regarded as the most ordinary and common night street snack, is different from home-made food by mothers as that is a symbol of family and kinship (亲属关系). The barbecue is where you go to become connected to people in society. And unlike official business lunches, during which people are rather reserved and polite, the barbecue lets people relax with old friends and new friends, leaving a lasting impression of friendship.The world, as a whole, holds deep-rooted good feelings toward the barbecue, either for the taste or the warmth produced by fire. “What we should do is to present the Chinese barbecue just the way it is because with its special ingredients (食材), ways of cooking, and more importantly, the special environment and people, the world will recognize it and might fall in love with it just as we do,” said Chen.32. What does Chinese Barbecue center on?A. The barbecued foods across China.B. The nightlife in large cities.C. The diverse street food.D. The story of barbecue stalls owners.33. How does Chinese Barbecue differ from Midnight Diner?A. It targets at the lonely.B. It has less conversation.C. It shows the eating habits.D. It focuses more on the diners.34. What can be inferred about the barbecue from Paragraph 4?A. It plays a role in people’s relationship.B. It influences people’s lifestyle.C. It is more delicious than home-made food.D. It serves as formal business lunches sometimes.35. Why did Chen Yingjie choose the barbecue as the topic of the series?A. To research a special way of cooking.B. To help the world understand China.C. To show the feature of Chinese food.D. To introduce the history of the barbecue.第二节（共5小题；每小题2分, 满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

After the science class, I had an English class. I thought it would be boring but later I found it very funny. When the classes of the morning ended I went to lunch. I sat outside the dining room with no one to talk to and no food because I was too nervous to join the lunch line. I kept looking around hoping to see someone I knew but I never saw anyone.Lunch ended and I went to have my art class. I was the first one there and not even my teacher was there yet. So I sat at my desk and started drawing some pictures. I didn't notice the rest of the class walking in or the girl that was standing behind me till I was surprised by the voice, "So what are you drawing?" It was a girl who had really long hair. She ended up being my best friend and one of the kindest and liveliest girls I know.In the next class meeting, the teacher asked us to talk about the past holiday.I was glad to make some new friends in the class. The first day of high school was hard for me but I got through it.71. What do we know about the writer's science class? __________A. She was 15 minutes late for it.B. She learned some class rules.C.

AMark Twain left school when he was twelve. He had little school education. In spite of this, he became the most famous writer of his time. He made millions of dollars by writing. His real name was Samuel Langhorne Clemens, but he is better known all over the world as Mark Twain，his pen name.Mark Twain was born in 1835 and he was not a healthy baby. In fact, he was not expected to live through the first winter. But with his mother's care，he managed to survive. As a boy，he caused much trouble for his parents. He used to play jokes on all his friends and neighbors. He didn't like to go to school, and he often ran away from home. He always went in the direction of the nearby Mississippi. He was nearly drowned nine times.After his father's death, Mark Twain began to work for a printer, who only provided him with food and clothing. Then，he worked as a printer，a riverboat pilot and later joined the army. But shortly after that he became a miner. During this period，he started to write short stories. Afterwards he became a fulltime writer.In 1870, Mark Twain got married. In the years that followed he wrote many books including Tom Sawyer in 1876, and Huckleberry Finn in 1884, which made him famous, and brought him great fortune. Unfortunately, Mark Twain got into debts in bad investments (投资) and he had to write large numbers of stories to paythese debts. In 1904, his wife died, and then three of his children passed away. At the age of 70, his hair was completely white. He bought many white suits and neckties. He wore nothing but white from head to foot until his death on April 21,1910.21．In his childhood, ________.A. he learned a lot at schoolB. he often went swimming with other boysC. his mother often worried about his safetyD. he often played games with other boys22．In order to make a living, Mark Twain ________.A. first worked as a printerB. did many kinds of workC. wrote stories in the beginningD. joined the army after he worked in a mine23．From the passage we can see that Mark Twain ________.A. had a happy childhoodB. was a good boy and always did what he was askedC. was very naughty when he was youngD. lived a pleasant life24．Before his death，Mark Twain ________.A. became a white manB. was in low spiritsC. liked to buy all kinds of clothesD. had nothing onBArriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a house for me and our children.During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.He reported the case to the police and then sat there，lost and lonely in astrange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband’s name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can（垃圾桶）that had been left out on the footpath.My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.That family not only restored the important documents to us that day but also restored our faith and trust in people. We still remember their kindness and often send a warm wish their way.25. What did Rashid plan to do after his arrival in Sydney?A. Go shoppingB. Find a houseC. Join his familyD. Take his family26. The girl’s parents got Rashid’s phone number from_______.A. a friend of his familyB. a Sydney policemanC. a letter in his papersD. a stranger in Sydney27. What does the underlined word “restored” in the last paragraph mean?A. ShowedB. Sent outC. DeliveredD. Gave back28. Which of the following can be the best title for the text?A. From India to Australia.B. Living in a a New Country.C. Turning Trash to Treasure.D. In Search of New Friends.CAmerica is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!29. Which of the following statements is TRUE according to the passage?A. Friendships between Americans usually extend deeply into their families.B. Friendships between Americans usually last for all their lives.C. Americans always show their warmth even if they are very busy.D. Americans will continue their friendships again even after a long break.30. The underlined words “generous with our time” in Paragraph 3 probably mean______.A. strict with timeB. serious with timeC. careful with timeD. willing to spend time31. A suitable title for this passage would probably be “______”.A. Friendships between ChineseB. Friendships between AmericansC. Americans’ hospitalityD. Americans’ and Chinese’s views of friendshipsDEveryone looks forward to progress, whether in one’s personal life or in the general society. Progress indicates a person’s ability to change the way he is living at the moment. Progress must lead a better way of doing things. All these, however, remains true only in so far as people want to accept technology and move forward by finding new and more efficient ways of doing things.However, at the back of the minds of many people, especially those who the “good old days”, efficiency comes with a price. When communication becomes efficient, people are able to contact one another no matter where they are and at whatever time they wish to. The click of a button allows people miles apart to talk or to see each other without even leaving their homes. With thecommunication gadgets, such as mobile phones and ipads, people often do not take the effort to visit one another personally. A personal visit carries with the additional feature of having to be in the person’s presence for as long as the visit lasts. We cannot unnecessarily excuse ourselves or turn the other person off.With efficiency also comes mass production. Such is the nature of factories and the success of industrialization today. Factories have improved efficiency. Unskillful tasks are left to machines and products are better made and produced with greater accuracy than any human hand could ever have done. However, with the improvements in efficiency also comes the loss of the personal touch when making these products. For example, many handcrafts(手工艺品) are now produced in a factory.Although this means that supply is better able to increase demand, now that the supply is quick and efficient, the demand might fall because mass production lowers the quality of the handicraft and it is difficult to find unique designs on each item.Nevertheless, we must not commit the mistake of analyzing progress only from one point of view. In fact, progress has allowed tradition to keep up. It is only with progress and the invention of new technology that many old products can be brought back to their old state. New technology is required for old products to stay old.It is people’s attitude towards progress that causes the type of influence that technology has on society. Technology is flexible. There is no fixed way of making use of it. Everything depends on people’s attitude. The worst effects of progress will fall on those who are unable to rethink their attitudes and views of society. When we accept progress and adapt it to suit our needs, a new “past” is created.32. According to Paragraph 1, progress can benefit people when they are willing to _______.A. live a better lifeB. look for better methodsC. change ways of livingD. accept technology and advance steadily33. The author explains “efficiency comes with a price” by _______.A. describing a processB. using examplesC. following time orderD. making classification34. Compared with home-made handicrafts, machine- made products _______.A. lack great accuracyB. lack the personal touchC. are of high valueD. are quite welcome35. What can be concluded from the last paragraph?A. Progress can suit the needs of daily life.B. People review the past with great regret.C. Technology should be introduced in a fixed way.D. People’s attitude decides the use of technology.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能够填入空白处的最佳选项。

D Moonlight Cinema.BAlmost every light comedy or situation comedy makes me feel like I should be drinking wine every night with my best friend while one of us tries on clothes. Not only should we share the same dress size, but we should also have a long, rich history of togetherness and secrets. Clearly, this is not reality.I have 598 f riends. OK, but if I’m honest, 99.3 percent of those friends are those I met only once or acquaintances who live too far away to see regularly. That leaves 4 people, who I can call anytime, not feeling like I’m absolutely wasting their time. The remaining 0.2, I’ve decided, is my houseplant. I can tell it anything.Feeling the same way？You’re absolutely not alone. Most of us find our “people” in school, but over time life changes：marriage, kids, etc. We grow out of our relationships and they grow out of us.So when the relationships come to an end, how do you find a new one？A woman in my apartment building, who I had seen around over the years, approached me one day and introduced herself. She bravely stated, “You seem cool. Do you want to hang out with me sometime？I’m looking for new friends.” I almost dropped my bag of groceries at her social honesty. And now we get together for coffee a few times a year, gossip （八卦）about the neighbors, and take in the mail when one of us is on vacation. But a few times a year isn’t enough for me.So, what counts as true friendship as you get older？For me, it’s feeling comfortable enough to be myself. And if you’re like me, it’s also trust — not just keeping the secret, but trusting that my life choices aren’t their gos sip elsewhere.25. What do the numbers in Paragraph 2 show？A. The author has some unusual friends.B. The author has very few real friends.C. The author is fond of phoning her friends.D. The author doesn’t like most of her friends.26. What does the underlined sentence in Paragraph 5 show？A. The author was a little careless.B. The author was glad at the request.C. The author was shocked by the request.D. The author was carrying something heavy.27. What does the author think true friendship is？A. It is really difficult to find.B. It can show one’s genuine belief.C. It is really hard for people to understand.D. It can make people have a sense of security.CIt's been said that honesty is the best policy．It sounds like the simplest thing in the world，but being truly honest with others and with yourself can be a real challenge．Most of us learned to be dishonest as children．Remember that dishonesty is rooted in fear，so you must look for and face those fears．By listing areas where you have a problem，and then working to deal with them，you can battle these habits．If you find yourself lying because you fear disapproval from someone，for example，perhaps you need to learn how to stop being a people pleaser and be yourself．Most importantly，admit your errors so that you can forgive yourself and use those experiences to reinforce your determination to do better．If you feel guilty for having been dishonest in the past，apologize to the person you lied to or find a creative way to make things right．If you've lied to a person who plays an important role in your life （a significant other，relative，or friend），the best （but most difficult）thing to do is to come clean．Think honestly．This may sound silly，but if you don't think honestly，you won't be honest．If you're pushed into a corner and don't know how to respond，you have the right to remain silent or say "Can we talk about this another time？ "or" I really don't feel comfortable talking about this．"Don't say "I don't know"Practice being honest on the simple things．Abraham Lincoln became famous for going to great lengths to return a few cents that did not belong to him，hence the nickname" Honest Abe"．By applying honesty to the little things，you will get in the habit of being honest in general．28．What's the author's attitude towards becoming honest？A．Optimistic．B．Pessimistic．C．Skeptical．D．Unconcerned．29．What does the underlined word “reinforce” in paragraph 1 mean？A．show B．strengthen C．express D．weak30．What's the author's main purpose of writing the text？A．To encourage people to be honest．B．To arouse readers 'interest in being famous．C．To call on people to learn from Abraham Lincoln．D．To advice us to say sorry to the person we lied to．31．Which of the following can be the best title for the text？A．Challenge Yourself B．No Need to Lie to OthersC．Honesty is the Best Policy D．Little Things Can Make a BigDifference．DClimate change will force exhausted birds migrating to Europe from Africa to travel further, with possibly disastrous consequences, according to a study.The annual voyage of some species, which fly north in search of food and suitable habitats, could increase by as much as 400 kilometers （250 miles）, the research found. “Maratho n migrations for some birds are set to become even longer,” said Stephen Willis, a professor at Durham University in Britain and the main architect of the study. “This is bad news for birds like the White throat, a common farmland bird. The added distance is a considerable threat. As temperatures rise and habitats change, birds will face their biggest challenge since the Pleistocene era （更新世）, which ended 11,000 years ago,” he said in a statement.Some 500 million birds migrate each year from Africa, some weighing as little as nine grams （three-tenths of an ounce）. To complete a voyage that can be thousands of kilometers long, birds have to fatten themselves up to twice their normal weight. Some even shrink their internal organs （收缩内脏） to become more fuel efficient, so any additional distance may be dangerous.The study finds that from 2007 to 2010, nine out of 17 species examined are going to face longer migrations, particularly birds that cross the Sahara Desert. Some birds travel the Sahara and the Mediterranean Sea in a one go, while others have a break in northern Africa before crossing. Many fly at night, when temperatures are cooler.A few — such as the Blackcap — have started to adapt by spending winters in Britain, but such behavior remains exceptional, the study said. The study forecasts that the migration distance of the Orphean Warbler will jump from 2,700 kilometers （1,700 miles）to between 3,050 and 3,350 kilometers （1,900 and 2,100 miles）, with even longer increases for the Subalpine and Barred Warblers.32. What does traveling extra distance mean for some migrating birds？A. Better living conditions.B. Better physical health.C. Stronger ability to fly.D. Bigger threat to life.33. To complete the marathon migrations, some birds have to do the following except ______.A. have a break in the SaharaB. put on more weightC. reduce the size of internal organsD. fly at night to avoid the heat34. What can we infer from the text？A. Birds have to migrate from Africa to Europe in winter.B. Global warming is bad for all birds worldwide.C. Birds that are of small size don’t need to migrate.D. Some birds have to migrate unless they adapt to climate change.35. What’s the best title of the text？A. Climate change leads to disastrous consequenceB. The annual voyage of some speciesC. How birds migrate for longer distancesD. Climate change pushes birds to migrate farther第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

2021年鹤壁市实验学校高三英语第四次联考试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIt's just before l pm and hungry guests are starting to emerge out onto the wooden floor at the back of the Victoria Falls Safari Lodge in Zimbabwe. A few have already settled in for lunch, drinking beer and enjoying their sandwiches and salads in the sunshine. It's a normal setting until you look up. Overhead, the sky is filled with several hundred vultures (秃鹭).They too have arrived for their midday snack. Every day the team at this hotel places last night's leftover meat out for the vultures to eat. They call it the "Vulture Restaurant" and it's a vital part of protecting these birds, who have become some of the most endangered species in Africa.In Zimbabwe, where illegal hunting of elephants and rhinos is a major issue, poisoning poses a significant threat to the birds. "In recent years hunters have realized they can use poison to kill animals. It's effective because it's silent and therefore doesn't attract much attention.when the vultures eat the bodies of the dead animals they die too," says Roger Parry, Wildlife Manager at the Victoria Falls Wildlife Trust.The Vulture Restaurant initiative is part feeding programme, part education programme. By attracting the birds to the Vulture Restaurant every day the team can ensure they're regularly getting a safe meal, and while the birds are there they can educate tourists from all over the world about these creatures.“Lunch” is served by Moses Garira. He has the unenviable task of wandering out into the middle of the clearing with a box full of meat, dropping the contents onto the ground and running for his life as the vultures fly downward suddenly for their food. No one, surely, would volunteer for this role, but Garira rather enjoys it. Back in the safety of the viewing seats, he tells the onlookers about the importance of vultures. "They're hugely important in terms of their role of cleaning up the bodies of dead animals," says Garira. "Notably, they're safely able to digest bacteria like anthrax. Without vultures, there'd be a lot more disease in the world."1. What's the biggest threat vultures facing in Zimbabwe?A. Overhunting.B. Unsafe food.C. Loss of habitat.D. A bird disease.2. What would others think of Garira's job?A. Scary.B. Relaxing.C. Well-paid.D. Time-consuming3. What do Garira's words mean?A. Birds are human's best friends.B. People know little about vultures.C. Vultures are environmentally favorable.D. Vultures are in urgentneed of protection.BIt’s 13:30 and 28-year-old Marten Pella 's smart phone starts pinging, a signal that it’s time for us to stop working around his living room table and instead start our workout routine together. A cartoon character wearing bright red shorts on video begins instructing us to do star-jumps and sit-ups around his apartment.Pella, a research assistant at Stockholm University, is part of the Hoffice movement, which invites workers-freelancers（自由职业者）or full-time employees who can do their jobs remotely—to work at each other’s homes to increase productivity and enjoy an active social life.Those attending Hoffice events advertised on Facebook are typically asked to work silently in 45-minute blocks, before taking short breaks together to exercise, or simply chatting over a coffee. In addition, each participant shares daily objectives with the rest of the group upon arrival, and is invited to report back on whether or not they have achieved them at the end of the day.“Often when I am alone, I can work focused for a couple of hours but then I’m easily distracted（分心）.The help of others makes me so much more disciplined.” says Pella, who attends Hoffice events as both a guest and a host. Lunches mean networking and connecting with new contacts. “People are coming from really different areas and have different professions so there can be really interesting discussions,” he says.The Hoffice movement has grown quickly since it was founded in 2014 by Swedish psychologist Christofer Franzen, now 37. He had been giving lectures on the benefits of collective（集体的）intelligence, but realised he was spending most of his own time working alone at his kitchen table. “I wanted to test more structured home co-working with friends in similar situations,” he says.Franzen says that holding events in houses and apartments creates a unique atmosphere, because there’s asense of community and desire to contribute. He’s looking for ways to expand the social value of Hoffice, by matching up members with relevant skills to share and even encouraging jobseekers to join its gatherings.4. Where is Pella when his smart phone starts pinging?A. In his own home.B. In his office.C. In another person’s home.D. At Stockholm University.5. What do people attending Hoffice events do first when they meet?A. Watch an exercise video.B. Work silently for 45 minutes.C. Tell each other their daily plans.D. Report what they have achieved.6. What does Franzen really mean by saying “friends in similar situations”?A. They usually work alone.B. They often give lectures.C. They study collective intelligence.D. They have to work at a kitchen table.7. What is the best title for the text?A. Sharing Comfortable WorkplacesB. A New Way to Make New FriendsC. Benefits of Collective IntelligenceD. Working from Others’ HomesCWhen my friend suggested going to the op shop (二手商店)，instantly I thought “I hope no one I know sees me”. It was the same when my cousin commented on my new furniture and Japanese, fine-bone-china bowls and asked where I got them. They were from the local op shop but instead I said “from the antique shop”.Many people in my Greek-Cypriot community would look down on me if I said I shopped at the op shop. They may pity me, consider me poor, a failure. Immigrants sacrificed their families and homes for a better life. Buying a house and having enough money to live comfortably, to educate your children and see them also live comfortably, are a big part of the immigrant dream, But has this dream made us materialistic at the cost of our own planet?Our love for purchasing the latest trendy clothes or furniture, then donating them when we are tired of them has become normal. I was once like this. But after watching the documentaryThe True CostI learned donated clothes that don’t get sold are sent to developing nations, many of them ending up in landfills (垃圾填埋地). In addition, your new dress requires electricity and materials to make. But if you buy a second-hand dress, that’s one less dress in a landfill and one less new dress to be made.A friend introduced me to op shopping only a few years ago. My firstitem was a dress she gifted me. It waslovely and I loved it. Nobody could tell it was second-hand. This opened me up to purchasing more second-hand high quality branded clothes. Once I visited a friend and was impressed by how she decorated her apartment. “It’s all second-hand,” she said. I couldn’t believe it. The truth is a lot of things sold at the op shop are in new or almost new condition. That’s when I made the decision to only buy second-hand things.Selling second-hand things isn’t anything new butwhat the planet needs is more buyers. There is so much excess (过量) production in the world. So stop feeling ashamed, and let’s get shopping.8. What kind of feeling is expressed in Paragraph 1?A. Pride.B. Embarrassment.C. Delight.D. Sympathy.9. Whatare many people in the author’s community like?A. They are probably materialistic.B. They care about the environment.C. They think highly of op shopping.D. They look down upon immigrants.10. What was the author encouraged to do after visiting her friend’s apartment?A. Watch the documentaryThe True Cost.B. Donate more to local charities.C. Avoid shopping too much.D. Stop buying new things.11. What’s the purpose of the text?A. To entertain.B. To advertise.C. To persuade.D. To describe.DWhen Alex Linwas 11 years old, he read an alarming article in the newspaper, which said that people were burying old computers in backyards, throwing TVs into streams, and dumping (丢弃) cell phones in the garbage. This was dangerous because e-waste contains harmful chemicals that can leak into the environment, getting into crops, animals, water supplies and people.Alex was really worried and decided to make it next project for WIN-the Westerly Innovations Network. Alex and six of his friends had formed this organization to help solve community problems two years before.But what could they do about this project with e-waste? The team spent several weeks gathering information about the harmful chemicals in e-waste and their effects on humans. They learned how to dispose(处置) of e-waste properly and how it could be recycled. Then, they sent out a Survey and found only one in eight knowwhat e-waste was, let alone how to properly dispose of it.Alex and his friends went into action. They advertised in the local newspaper and distributed notices to students, asking residents to bring their unwanted electronics to the school parking lot. The drive lasted two days, and they collected over 9, 500 kilograms of e-waste. The next step was to set up a long-term e-waste drop-off center for the town. After some research, they’d learned that reusing is the best way to deal with electronic devices and it is seven times more efficient than recycling. So, they began learning to retrofit (翻新) computers themselves and distributed them to students who didn’t have their own. In this way, they could help students in the area and protect the environment at the same time.For a lasting solution to e-waste, the drop-off center wasn’t enough. Lawswould have to be passed. In 2016, WIN helped push for an e-waste bill in their town, which required companies that manufactured or sold electronics to take back e-waste. The bill clearly forbids the dumping of e-waste. Because of the work of WIN, more and more people, like Alex and his team, are getting the message about safe disposal of e-waste. As Alex says, “Today’s technology should not become tomorrow’s harmful garbage.”12. What was Alex’s worry after he read the article?A. The littering of e-waste.B. The recycling of plastic.C. The change of environment.D. At 11 p.m. on Monday.13. What did Alex do to start the project?A. Set up WIN.B. Collect information.C. Ask friends for help.D. The overuse of old computer.14. Which can best describe the way Alex and his team did their work?A. Traditional.B. Competitive.C. Scientific.D. Convenient.15. What message does the story convey?A. There is no end to perfection.B. success comes through failure.C. Every positive attitude has a reward.D. young people can make a big difference.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。

Long-standing． D. World-class．BWe touch our faces all the time, and it had never seemed to be a big problem—until COVID-19 arrived. Touching our faces—the "T-zone" of our eyes, nose and mouth in particular—can mean giving ourselves the deadly virus.This is why organizations like the Centers for Disease Control and Prevention (CDC) have suggested that we avoid touching our faces. "Just stop this simple behavior," William Sawyer, founder of Henry the Hand, a nonprofit organization that promotes hand hygiene (卫生), told The Washington Post. "It's the one behavior that would be better than any vaccine (疫苗) ever created."Yet, stopping this "simple" behavior might be harder than you think because it's already hardwired (固定存在于) into our system.Some face touchingis an automatic reflex (反射) —like when there is an itch (痒) on your nose, you'll scratch (挠) it without thinking. According to CNBC, a 2014 study found that touching your face also helps to reduce stress and regulate emotions. For example, you're more likely to do it when you feel awkward or embarrassed. According to Dacher Keltner, a psychologist at the University of California Berkeley, US, this action may also come with a social function: When you are talking to someone and want to change the subject, for example, touching your face is like "the curtains on a stage, closing up one act of the social drama, ushering (引导) in the next," Keltner told the BBC.Moreover, face-touching in almost all of these occasions is subconscious, which means it's very hard to change "because you don't even know you're doing it", said Sawyer. But you're not alone. In a 2015 study, wherea group of medical students were filmed in class, it was found that they touched their faces an average of 23 times an hour—with 44 percent of the touches being in the "T-zones". That was particularly surprising since medical students were supposed to know better.Since it's so hard to shake the habit, maybe the easiest way is to wash our hands more often. This way, we can be sure that our hands are free from the novel coronavirus.4. What do the first two paragraphs talk about?A. The best way to fight COVID-19B. How organizations are fighting COVID-19.C. Typical hand hygiene problems in the fight against COVID-19.D. The necessity to avoid touching our faces to fight COVID-19.5. Why is it hard for people to stop touching their faces?A. It makes people feel more confident.B. Many are unaware of this behavior's risks.C. They usually do it automatically and subconsciouslyD. Many think the action helps them express their emotions.6. Which of the following is a social function of touching faces, according to the text?A. Using it as a sign to change the topicB. Bringing a conversation to an end.C. Showing an interest in the ongoing subject.D. Making others feel relaxed while talking.7. What is the author's purpose in mentioning a 2015 study on a group of medical students?A. To give tips on how to stop touching faces.B. To prove that it is common for people to touch their faces.C. To show it is impossible to shake the habit of touching your face.D. To show how hygiene awareness helps people avoid touching their faces.CI cried the first time I saw the Notre Dame（巴黎圣母院）years ago. I'd waited my entire life to see this great French architecture, and experienced it in its full glory on a bright sunny day. Last night, I again cried for the centuries-old church while watching it burn.I hadn't expected to spend my evening that way. My friend and I were having dinner at a cafe a block or so away from the Notre Dame, choosing to skip going inside with the intention to go back the next day.However, we heard that it caught fire, so we left the cafe and ran towards the church, following heavy smoke from it, and soon we joined a nearly silent crowd. Some were praying, some were crying, but most were staring in disbelief at the disaster happening before us. The fire continued to get worse. About 400 firefighters were working to control the fire. We could see their flashlights shining as they inspected the front from a balcony.The Notre Dame is part of the heartbeat ofParis, I reflected on the experiences I've had there, from attending a bread market out front to admiring the beautiful windows and architecture inside. It is a spot that helpsmakeParismagical. And here we were, watching it burn down. It was too much to handle, but it was impossible to look away.About 9：30 pm, the gathered crowd spontaneously（自发地）began to sing Hymns（圣歌）to the church. We sang along with the group, feeling at once less like tourists and more like members of them. I hadn't imagined all that before.For hundreds of years, the Notre Dame hasseen the most joyous and the most terrible moments in the lives of both France and her people. And when everyone was able to become one emotional force, it showed that even in her darkest hour, the Notre Dame was still there to bring us all together.8. Why did the author cry for the Notre Dame for the first time?A. She was touched by its greatness.B. She was sorrowful to watch it burn.C. She was regretful for missing its glory.D. She was excited about French cultures.9. What was the author doing when the Notre Dame caught fire?A. Heading for a faraway cafe.B. Visiting a church with a friend.C. Eating nearby with a friend.D. Wandering along the street alone.10. What can we know about the fire scene?A. People expressed their sadness in different ways.B. People were nervously rushing in different directions.C. Hundreds of volunteers joined in putting out the fire.D. Firefighters kept people away with shining flashlights.11. What impressed the author most?A. The church allowed visitors to gaingreat experiences.B. Many foreign tourists became members of the church.C. The church survived disasters for hundreds of years.D. People were brought together to sing to the church.DThe Chinese philosopher (哲学家) Confucius once said, “Time flows away like the water in the river.” This is especially true as the novel coronavirus pneumonia outbreak has affected millions of people in China, andthe whole nation has been working day and night to fight the epidemic.In late January, when an increasing number of people in Wuhan were suspected to be infected, and hospitals didn't have adequate beds for them, two special hospitals—Lei shenshan Hospital and Huo shenshan Hospitalwere built. These two makeshift (临时的) hospitals were built to treat pneumonia patients infected with the novel coronavirus.HuoshenshanHospitalhas 1,000 beds and covers 33,900 square meters, andLeishenshanHospitalhas 1,500 beds and a total area of about 79,000 square meters. More than 4,000 workers worked 24/7 in two shifts, and nearly 1,000 large-scale pieces of equipment and transport vehicles helped the project on site. The two hospitals were built in an amazingly short time. It only took 10 days for people to build Huo shenshan, and 14 days for Lei shenshan.This certainly wowed many people overseas. “It's incredible that two hospitals with 2,500 beds can be built in a short period. It's just hard to believe,” a foreigner named Stuart told People's Daily. In the meantime, Chinese companies have also taken actions quickly in this battle.“The automobile industry is highly industrialized with strong capabilities in comprehensive manufacturing, purchasing materials, production lines and output of technologies,” Shi Jianhua, deputy secretary-general of China Association of Automobile Manufacturers, told CCTV News. “In this special time, when the nation needs more masks, it's time for us to quickly respond and shoulder the social responsibilities.”Indeed, a fast response is crucial in any crisis. In this special time,Chinacan't afford to waste a second in the fight against the epidemic. After all, time equals life during this crisis.12.
