Thesnowboarding champion, who grew up in California, competed there at17 years of age. She became the youngest woman ever to win anOlympic gold medal in the half-pipe competition.She has recently won a halfpipe competition during the Winter X Games in Aspen, Colorado. But the 18yearold snowboarder has decided to trade some trips down the half-pipe for an Ivy League education after the world championship competition in Utah. Beginning in the next fall, Kim will be joining Princeton University’s class. Instead of centering on the physics of her winning snowboard moves, she could now be learning the subject in school. In a recent interview, Kim said, “While I have a special identity and my life has always been so different, I still aim to make my higher education experience as normal as possible.”Kim added, “I’d love to be Chloe, the girl who sits next to me in the English class.”Kim received widespread attention during the Pyeongchang Winter Olympics. Her publicity was fueled by her friendly, energetic nature as well as her interesting family story. Along her path to Olympic gold, Kim also became a social media star. She helped design a snowboarding Barbie doll in her likeness, rapped with hiphop artist GEazy and joined other sports stars to be honored with ESPY Awards(年度卓越体育表现奖). While all of these are fun, Kim says she now looks forward to a new challenge—earning a degree from one of America’s top universities. She says she considers her acceptance to Princeton just as much of an honor as earning an Olympic gold medal.She is still considering what her exact field of study will be at Princeton. But she says it will involve something science-related, possibly chemistry or biology. She is attempting to work out a plan that will permit her to keep training while going to classes. Kim says her sports and educational goals go hand in hand. “It’s all about progressing the sports and also pushing myself,”she said. “To see what I can do, and how far I can go.”【解题导语】本文介绍了美国的冬奥会冠军克洛伊·金在获得多次单板女子滑雪比赛冠军后,决定要像普通人一样投身于文化知识的学习中。

请在40分钟内完成)班级____________学号____________姓名____________得分____________一、阅读理解阅读下列短文,从每题所给的A、B、C和D项中,选出最佳选项。
(共10小题;每小题2分,满分20分)AWhat would you like to be when you grow up? A teacher? A doctor? An astronaut? What do you need to do to achieve your dream job?Perhaps you think that studying well and then going on to work hard will get you the successful career you want. We are constantly taught that our hard work will eventually pay off.But a government survey has shown that hard work is not the only thing that will help you to move up the ladder. Two thirds of people believe that who you know matters more than what you know when it comes to social activity. So are the connections that you have more important than your education?Seventy-six percent of the people in the survey believed that family background is important in influencing your chances of success. They believe that if you are privileged from birth, you are more likely to have a successful career, especially if your family is wealthy.Even if you don’t have a privileged background, the people you know can still make a difference to your career. Networking is a skill which is encouraged by many career advisers. Some companies run networking workshops to try and encourage staff to meet other people, to communicate and build relationships. It’s a valuable skill.But the survey also showed something quite interesting. Although most people believed that networks are more important than education, many people put their own career success down to talent, rather than background. 41% of the people said that their parents’ income had influenced their life, but at the same time, another 41% believed that they had achieved their own success.So which is more important, what you know or who you know? It seems that by working hard and making lots of connections, the answer may be that both are very important.1. Which of the following is closest in meaning to the underlined part?A. Practice makes perfect.B. Nothing is impossible.C. Hope for the best.D. No pains, no gains.2. According to the government survey the most important factor to help people move up the ladder is .A. hard workB. educationC. social relationshipD. social activity3. Which of the following is NOT true according to the passage?A. 76% of the people think social relationship matters most.B. 41% of the people believe parents’ income is most important.C. 76% of the people think family background ranks first.D. 41% of the people believe they gained their own success.4. From the passage we can infer that the writer writes the article to .A. stress the importance of educationB. challenge the traditional beliefC. make lots of social connectionsD. encourage people to work hard5. Which of the following is the best title for the passage?A. The Way to SuccessB. Keep your Dream in MindC. A Wealthy and Smooth CareerD. A Survey on People’s Dreams[助读词汇]career n. 生涯constantly adv. 不断地;时常matter vi. 重要privileged adj. 享有特权的put down to 归因于BI have been a music fan ever since I was a little kid. It must have been my eldest brother who brought me to the world of music, which later in my life became the source of happiness and sadness. My brother liked to play the dizi (曲笛), a very traditional musical instrument which was very popular in the 1970’s. Greatly influenced by his enthusiasm to music, I learned to play the dizi in my spare time.Do you know what the most popular form of culture was in the 1970’s? The so-called model dramas, that is,“modern revolutionary Beijing opera”, which were officially formed during the Cultural Revolution. Their materials were from the communist activities or related subjects. From morning till night, you would hear them broadcast over and over again. Frankly speaking, model dramas served as my guide to music to some extent because the music was really wonderfully made.Later I met my desk-mate, who was then also a music lover. Having much in common, we soon became good friends. Very often we listened to the radio, learned new songs and then sang them on our way home. I still remember one day in class we even put our radio beneath the surface of our desk and kept our ears close to it, listening to the pop songs of that time with the teacher giving his lesson in front. Does it shock you? At the beginning of the 1980’s, films were very much popular with young people and the songs in them would soon become the hits. At the same time, many film stars like Liu Xiaoqing, Chen Chong captured the hearts of us late 1960’s generation.I spent my high school days in the world of music and continued my passion for music in my spare time in my following years.1. The author of the passage began his musical hobby with _________.A. Beijing operaB. radio broadcastC. filmsD. dizi2. The author is probably in his _________.A. 30’sB. 40’sC. 50’sD. 60’s3. Which of the following is NOT true according to the passage?A. D izi was played by many people in the 1970’s.B. The music from model dramas was fantastic.C. Liu Xiaoqing and Chen Chong were the most famous stars in 1960’s.D. Author and his desk-mate had common interests.4. It can be inferred from the last paragraph that _________.A. the author did a bad job in his studies at schoolB. the author must be very old at the very presentC. the author decided to be a musician in the futureD. the author’s love for music has never decreased5. The author writes this passage _________.A. to tell readers how he began his musical hobbyB. to tell readers about Beijing operaC. to tell readers something about his teacherD. to recall his life of his childhood and middle school[助读词汇]so-called adj. 所谓的drama n. 戏剧communist adj. 与共产党有关的beneath prep.在……下方hit n. 轰动一时的歌曲capture vt.捕获passion n. 激情the Cultural Revolution 文化大革命related subject 相关主题frankly speaking 坦白地说to some extent 在一定程度上have much in common 有很多共同点二、完形填空阅读下面短文,从短文后各题所给的A、B、C和D项中,选出可以填入空白处的最佳选项。

Unit 5 B卷一、阅读理解AFlying in 2050 is going to be a real pleasure,the engineers at European manufacturer Airbus say,with 360-degree views whenever the“intelligent cabin membrane(客舱壁)”is set on transparent(透明的).One of their new ideas involves absorbing passenger body heat to meet some of the plane's energy needs,while another refers to seats with self-cleaning fabrics(纺织品)that adapt to each individual body form.The first,business and economy class system would be abandoned,and replaced by individual seating arrangements.The air would be vitamin-enriched,while passengers could enjoy virtual games of golf high up over the clouds,go shopping,or try on the latest fashions in virtual changing cabins.This cabin of the future,whose shape is modeled after that of birds,is part of Airbus's total concept for 2050.CEO Thomas Enders says the company expects the demand for aircraft to go up worldwide despite the on-going problems faced by many airlines,particularly in Europe.“Air travel continues to hold more long-term growth potential than any other sector(领域),”Enders said.According to Airbus figures,air travel currently makes up 8%,or 580 billion dollars worth of the European GDP.Airbus engineer Champion says that the three biggest current challenges are that people want flying to be cheap,efficient and environmentally friendly.The sector has to find satisfactory ways of meeting these demands,which is why flying will probably look completely different a few decades down the road.“By 2050,the sector will be carrying 9 billion passengers around the world,”Champion says.Airbus' visions for the airports of the future no longer include gates.Instead,planes would roll right up to a station,with passengers boarding quickly through several doors,using touch screens to check in.But Champion says the airports themselves may be slow to adjust.“We can come up_with_all_kinds_of_great_stuff,but when a_plane_has_to_circle_for_40_minutes_over_Heathrow_before_landing,a_lot_of_it_gets_lost.”1.According to the engineers,future planes ______.A.will offer passengers a full view of the skyB.will allow people to play golf on boardC.will be safer than any other means of transportD.will be the most environmentally-friendly ever2.CEO Thomas Enders tends to think that ______.A.a cabin shape modeled after the shapes of birds is bestB.air travel has great potential for economic growthC.European airlines are facing the most serious challengesD.the level of air-travel employment remains high worldwide3.What is implied in the text?A.Airbus will lead the industry.B.Passengers should be happy with the coming changes.C.More people will fly on Airbus planes by 2050.D.Passengers will be completely satisfied with the services of Airbus.4.With the underlined statement,Champion means that ______.A.airports ought to have more gatesB.planes in the future will need more time to landC.there should be more doors for passengers to check inD.the airports have to be changedBMost American kids love Halloween treats,but a bucket of Halloween candy can be a dentist's nightmare.Some parents try to get rid of half of the candy after their children go to bed,but dentists say parents also need to separate the good kinds of treats from the bad ones.It is not exactly what a child eats that truly matters,but how much time it stays in his mouth.According to pediatric dentist Dr.Kaneta Lott,the most damaging stuff is something that is sticky or very hard and thus stays in the mouth for a long time.This is because we all have bacteria in our mouths.When we eat,the bacteria take our food as their food and produce an acid that destroys the surface of the teeth,causingcavities to form.The longer the food stays in the mouth,the more likely cavities will develop.Therefore,potato chips are worse than candy because they get stuck between teeth.For the same reason,raisins and crackers are not the best choice.Hard candies take a long time to consume and are also a bad choice for Halloween treats.If children really love candy,dentists recommend that they eat chocolate instead.Unlike hard candies,chocolate dissolves quickly in the mouth.Besides,chocolate contains tannins,which help to kill some of the bacteria in the mouth.But no matter what a child eats,brushing after each meal is still the best way to fight cavities.5.What is the main purpose of this passage?A.To discuss how cavities can be treated.B.To point out the problems with Halloween celebrations.C.To tell parents what sweets are less damaging to their children's teeth.D.To teach parents the meaning of Halloween candy for their children.6.Why are hard candies especially bad for teeth?A.They may break the children's teeth.B.They contain too much sugar.C.They help bacteria to produce tannins.D.They stay in the mouth for a long time.7.According to the passage,which of the following is a better choice for Halloween treats?A.Chocolate.B.Crackers.C.Raisins. D.Potato chips.8.According to the passage,which of the following is TRUE of tannins?A.They are produced when the bacteria digest the food.B.They help to get rid of some bacteria in the mouth.C.They help chocolate to dissolve more quickly.D.They destroy the surface of the teeth.二、任务型读写阅读下面短文,根据所读内容在表格中的空白处填入恰当的单词。
