Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, and C. Choose the one that fits best according to the information given in the passage you have just read.(A)“Everything happens for the best,” my mother said each time I faced disappointment or even depression. “If you carry on, one day something good will happen. And you’ll realize that it wouldn’t have happened if not for that previous disappointment.”Mother was right, which I didn’t discover until after graduating from college in 1932. I had decided to try for a job in radio, then work my way up to sports announcer. I hitchhiked to Chicago and knocked on the door of every station—and got turned down every time. In one studio, a kind lady told me that in most cases big stations couldn’t risk hiring an inexperienced person. “Go out in the remote areas and find a small station that’ll give you a chance,” she said. I went back home to Dixon, Illinois.While there were no radio-announcing jobs in Dixon, my father said Montgomery Ward had opened a store and wanted a local athlete to manage its sports department. Since Dixon was where I had played high school football, I applied. The job sounded just right for me.But I wasn’t hired. My disappointment must have shown. “Everything happens for the best.” Mom reminded me. Dad offered me the car to hunt for jobs. I tried WOC Radio in Davenport, Iowa. The program director, a wonderful Scotsman named Peter MacArthur told me they had already hired an announcer.As I left his office, my frustration boiled over. I asked aloud, “How can a fellow get to be a sports announcer if he can’t get a job in a radio station?” I was waiting for the elevator when I heard MacArthur calling, “What was that you said about sports? Do you know anything about football?” Then he stood me before a microphone and asked me to broadcast an imaginary game. The preceding autumn, my team had won a game in the last 20 seconds with a 65-yard run. I did a 15-minute boost to that play, and Peter told me I would be broadcasting Saturday’s game!On my way home, as I have many times since, I thought of my mother’s words, “If you carry on, one day something good will happen. Something wouldn’t have happened if not for that previous disappointment.”76. We learn from the passage that ________.A. the frustration of the author prevented him from performing well at WOC RadioB. both of the author’s parents showed support when he was trying to search for a jobC. Peter MacArthur recognized the author’s talent in broadcasting after reading his resumeD. the author lost all his hope and courage when he was turned down by Montgomery Ward77. What was most likely the author’s attitude towards Peter MacArthur?A. He was worried that Peter wouldn’t believe in his ability.B. He was afraid that his loud inner claim would annoy Peter.C. He was angry that Peter didn’t offer him a satisfying position.D. He was grateful that Peter could notice his broadcasting potential.78. What lesson can you learn from the author’s experience in the passage?A. Well begun is half done.B. Prevention is better than cure.C. No cross, no crown.D. Rome was not built in a day.(B)Australian scientists are trying to give kangaroo-style stomachs to cattle and sleep in order to cut the greenhouse gases they send out, which is thought to be responsible for global warming.Thanks to special bacteria in their stomachs, kangaroo flatulence (肠胃气胀) contains no methane (甲烷) and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas.While the usual image of greenhouse gas pollution is a billowing smokestack (烟囱) pushing out carbon dioxide, farm animals’ passing wind contribute a surprisingly high percentage of total emissions in some countries.“Fourteen percent of emissions from all sources in Australia is from enteric methane fromcattle and sheep,” said Athol Klieve, a senior research scientist with the Queensland state government.“And if you look at another country such as New Zealand, which has got a much higher agricultural base, they’re actually up around 50 percent,” he said.Researchers say the bacteria also makes the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers.But it will take researchers at least three years to isolate the bacteria, before they can even start to develop a way of transferring it to cattle and sheep.Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos. And about 20 percent of health-conscious Australians are believed to eat the national symbol already.“It’s low in fat, it’s got high protein levels and it’s very clean in the sense that basically it’s the free-range animal,” said Peter Ampt of the University of New South Wales’s institute of environmental studies.79. Scientists intend to put bacteria into cattle and sheep_______.A. to prevent them from sending out harmful gasesB. to help Australian farmers to earn more moneyC. so that they can protect Australian ecosystemD. so that they can make full use of special bacteria80. Athol Klieve seems to believe that ___________.A. cattle and sheep produce more carbon dioxideB. less cattle and sheep are raised in New ZealandC. farm animals are to blame for greenhouse gasesD. New Zealand has the most animals in the world81. The advantages Peter Ampt lists about kangaroos don’t include _________.A. it is rich in proteinB. is low in fatC. it is cheaper than beefD. it is cleaner than sheep(C)Too much work, too little money and not enough opportunity for promotion or growth are stressing us out on the job, according to a new survey from the American Psychological Association.We all know that stress reduces all of the things that help productivity—mental clarity(清晰), short-term memory, decision-making and moods. One-third of employees experience lasting stress related to work, the survey found. Fifty-four percent of the 1,501 employed adults surveyed say they feel they are paid too little for thei r contributions, and 61% said their jobs don’t offer adequate opportunities to advance. Only half of the adults surveyed said they feel valued at work.Besides, women’s stress is rising as families rely more on women’s earnings. An employed wife’s contrib ution to family earnings has reached, on average, 47% since 2009, so women feel especially stuck and tense. Thirty-two percent of women said their employers don’t provide sufficient opportunities for internal advancement, compared with 30% of men. Women are more likely to feel tense during a typical workday, reporting more often that their employer doesn’t appreciate what they do.Physically, the body responds to stress by secreting hormones into the bloodstream that stimulate accelerated(加速的) heart rate and breathing and tensing of muscles. People who experience stress as a positive often have increased blood flow to the brain, muscles and limbs, similar to the effects of aerobic exercise. Those who feel frightened or threatened, however, oftenhave an unstable heart rate and constricting blood vessels(血管). Their blood pressure rises and hands and feet may grow cold. They may become agitated, speak more loudly or experience errors in judgment.Emotional responses to stress often divide along gender lines, with men more likely to have a “fight or flight” reaction while women are more likely to have a “tend and befriend” response, seeking comfort in relationships and care of loved ones, according to the research.Women tend to “internalize”, which contributes t o their stress. Many women hesitate to speak up for themselves or challenge behavior they see as unfair. Kay Keaney, interior designer, 40, rose fast at a California medical group, taking on responsibility for interior and facility planning. With her 60-hour workweeks, plus early-morning and late-night meetings and a 1.5-hour commute each way, she seldom had time with her two small children. Whether stuck in traffic on her way to a 6 p.m. pickup at day care, or torn between her children and urgent work emai ls, “I just wanted to crawl out of my skin,” she says. “I was overwhelmed.” Yet she hesitated to complain. “There was too much work to be done, and playing the Mommy card was bad form.”But the experts suggest that women should give themselves a voice.82. The underlined word “agitated” in Paragraph 4 is closest in meaning to _______.A. fearfulB. optimisticC. anxiousD. ambitious83. Which of the following statements is TRUE according to the passage?A. Everyone has a painful sense of being under-appreciated or under-paid.B. An increasing number of people feel satisfied with work-life balance.C. An improving job market is making some people’s work lives easier.D. Most women have higher levels of work stress than the opposite sex.84. We can learn from the example of Kay Keaney that _____.A. relieving oneself from stress involves being frank as well as braveB. experiencing symptoms of lasting stress causes communication barriersC. seeking comfort from friends or relatives has little to do with office stressD. being challenged or devalued by others leads to numerous health problems85. What is most probably to be discussed in the following paragraphs?A. Other aspects in life affected by stress in work.B. Tips to help women handle their hard times properly.C. Examples to show the different gender responses to stress.D. Reasons why people are likely to feel tense when working.DUniversity educators largely think highly of the wonders of teaching through technology, but skeptics question whether something is lost when professors and lectures rely too heavily on electronic media or when interaction with students takes place remotely — in cyberspace rather than the real space of the classroom. Hans Ulrich Gumbrecht, the Professor of Literature at Stanford University, is one such skeptic. “I think this enthusiastic and sometimes childish and blind pushing toward the more technology the better, the more websites the better teacher, and so forth, is very dangerous — is, indeed, suicidal,” he indicates.However, Gumbrecht warns that there are few, if any, studies either supporting or rejecting thehypothesis that traditional ways of teaching are superior to teaching via the Internet. He says that he could point only to his “intuition that real classroom presence should be maintained,” and emphasizes the need for educators to examine critically where technology serves a useful pedagogical (教学法的) function and where it does not.Yet, Gumbrecht allows that, for courses in which knowledge transmission is the sole purpose, electronic media probably can do the job well enough. Indeed, given the 20th century’s knowledge explosion and the increasing costs of higher education, using technology as opposed to real-life teachers for the transmission of information is probably inevitable, he admits. In any case, knowledge transmission should not be the core function of the university, he maintains, noting that universities should be places where people confront open questions, places for “intellectual complexity” and “riskful thinking”.“We are not about finding or transmitting solutions; we are not about recipes; we are not about making intellectual life easy. Confrontation with complexity is what expands your mind. It is something like intellectual gymnastics. And this is what makes you a suitable member of the society.”Moreover, discussions in the physical presence of others can lead to the intellectual innovation. “There’s a qualitative change, and you don’t know how it happens. Discussions in the physical presence have the capacity of being the catalyst (催化剂) for such intellectual breakthroughs. The possibility of in-classroom teaching — of letting something happen which cannot happen if you teach by the transmission of information — is a strength.”86. Which of the following is the best title to this passage?A. Cyberspace InteractionB. The Core Function of the UniversityC. Information Transmission Cannot Help You SurviveD. Electronic Teaching Arouses Uncertainty87. Which of the following might Professor Gumbercht support?A. Professors should be keen on teaching technique innovation.B. Technologies applied to classrooms strength creative thinking.C. Traditional pedagogical function has its place in classroom.D. The core function of the university is to focus on knowledge transmitting.88. Cyberspace teaching could replace real-life teachers EXCEPT when ________.A. transmitting knowledge is the only purpose of the courseB. there’s too much knowledge to put across to the studentsC. the cost of college education increases greatlyD. open questions without possible answers are encouraged89. According to the passage, discussion in the physical presence of others can ________.A. lead to greatly improved intellectual abilitiesB. lead to easier and stronger transmission of informationC. produce certain energy for intellectual breakthroughsD. produce qualitative change in teacher-students relationshipsTranslation 17% (前三句各3分,后两句各4分)Directions: Translate the following sentences into English, using the words given in the brackets.90. 不要让吸烟剥夺你的健康。

由这些数据可推算出 ( )A.地球表面和火星表面的重力加速度之比为5:1B.地球表面和火星表面的重力加速度之比为10:1c.地球和火星的第一宇宙速度之比为:1D.地球和火星的第一宇宙速度之比为:1参考答案:C3. 如图5所示,将物体A放在容器B中,以某一速度把容器B竖直上抛,不计空气阻力,运动过程中容器B的地面始终保持水平,下列说法正确的是()A.在上升和下降过程中A对B的压力都一定为零B.上升过程中A对B的压力大于物体A受到的重力C.下降过程中A对B的压力大于物体A受到的重力D.在上升和下降过程中A对B的压力都等于物体A受到的重力参考答案:A由于不计空气阻力,物体A和容器B均处于完全失重状态,故A、B之间的相互作用力为0.只有选项A正确。
4.(单选)如图,表面处处同样粗糙的楔形木块abc固定在水平地面上,ab面和bc面与地面的夹角分别为α和β,且α>β.一初速度为v0的小物块沿斜面ab向上运动,经时间t0后到达顶点b时,速度刚好为零;然后让小物块立即从静止开始沿斜面bc下滑.在小物块从a运动到c的过程中,可能正确描述其速度大小v与时间t的关系的图象是().B.C.D.参考答案:解:设物块上滑与下滑的加速度大小分别为a1和a2.根据牛顿第二定律得:mgsinα+μmgcosα=ma1,mgsinβ﹣μmgcosβ=ma2,得a1=gsinα+μgcosα,a2=gsinβ﹣μgcosβ,则知a1>a2而v﹣t图象的斜率等于加速度,所以上滑段图线的斜率大于下滑段图线的斜率.上滑过程的位移大小较小,而上滑的加速度较大,由x=知,上滑过程时间较短.因上滑过程中,物块做匀减速运动,下滑过程做匀加速直线运动,两段图象都是直线.由于物体克服摩擦力做功,机械能不断减小,所以物体到达c点的速度小于v0.故C正确,ABD错误.故选C5. 在同一水平直线上的两位置分别沿同一水平方向抛出两小球A和B,其运动轨迹如图所示,不计空气阻力.要使两球在空中相遇,则必须A.先抛出A球B.先抛出B球C.同时抛出两球D.A球的水平速度应大于B球的水平速度参考答案:CD由于相遇时A、B做平抛运动的竖直位移h相同,由h= gt2可以判断两球下落时间相同,即应同时抛出两球,选项C正确,A、B错误.物体做平抛运动的规律水平方向上是匀速直线运动,由于A的水平位移比B的水平位移大,所以A的初速度要大,选项D正确.故选CD.二、填空题:本题共8小题,每小题2分,共计16分6. 某同学设计了如下实验方案用来‘验证牛顿运动定律’:(1)如图甲所示,将木板有定滑轮的一端垫起,把滑块通过细绳与带夹的重锤相连,然后跨过定滑轮,重锤下夹一纸带,穿过打点计时器。

For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.Highly gifted children benefit from explanation as much as their peers Schools tend to assume that highly gifted children can manage by themselves and that they do not need any extra support. As a result, they sometimes seem (21) ________ (forget). Psychologist Bart Vogelaar conducted a research and discovered that a high gift does not mean (22) ________ (perform) to the children’s maximum capacity. He finds out that this group too benefits from training and explanation and that strangely enough, the benefits are the same (23) ________ both groups.In his research, Vogelaa made use of dynamic tests(动态测试), (24) ________ ________ children received training and their progress was measured afterwards to give a better image of their learning capabilities. 522 children aged between five and ten years -- 173 highly gifted and 349 averagely gifted -- took part in (25) ________ was so-called learning potential test.

Schirrmann went on to 3 the German Youth Hostel Association in the year 1919. By this time, the idea of the youth hostel had 4 far and wide, all over the lands of Europe and further.And then, in the year 1932, a(n) 5 organization called the International Youth Hostel was founded in Amsterdam, which consisted of youth hostels from Switzerland, Germany, Poland, the Netherlands, Norway, Britain, Ireland, France, Czechoslovakia, Denmark and Belgium. Richard Schirrmann became its chairman in 1933.The idea of the youth hostel is for young people who are on nature trips to get 6 accommodation in exchange for some money and a helping hand with the domestic chores(家务活). These hostels were said to build character and a sense of independence, as the youth who stayed in them got the 7 to see how other people lived as well as to help to do work.Youth hostels are also places to meet and make new friends. They have no class 8 and everyone has to do their share. Here, wealth and position does not help you gain 9 , but friendliness does. The friendlier you are, the more you learn from the 10 of staying in a youth hostel.II.

Later, I saw Stephen with the two ___3___ ones while his brother was using the beat-up ones.”“____4__ the extended family, and you’ll probably find a bossy grandparent, aunt, uncle or cousin in every ___5__. It’s an inheritable trait,” says Russell Barkley, a professor at the Medical University of South Carolina. Other children who may not be particularly bossy can gradually gain dominance ___6___ they sense their parents are weak, hesitant, or in disagreement with each other.Whether it’s inborn nature or developed ___7___ at work, too much control in the hands of the young isn’t ___8___ for children or the family. Fear is at the root of a lot of bossy behavior, says family psychologist John Taylor.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.AYu Pengnian is an 88-year-old real estate Chinese businessman. He amassed a fortune of $1.3 billion dollars during his career but instead of keeping the money and living like an emperor, he decided to give it all away. All of his fortune will be spent on helping poor Chinese students get a better education.And Yu isn’t the only super-rich person in China who has this spirit of giving. Chen Guangbiao, a Jiangsu recycling tycoon, has given millions of dollars to charity and promises to give all of his money to charity when he dies.Yu and Chen are among the many businessmen who have become prosperous during China’s economic rise. An American business magazine, Forbes, estimates that there are 117 billionaires in China and hundreds of thousands of millionaires. What sets Yu and Chen apart from the rest, though, is their tremendous generosity when it comes to donating money to charity.Last week Bill Gates and Warren Buffett came to Beijing. Gates and Buffett, two of the world’s richest men, are also the world’s biggest philanthropists. They invited fifty of China’s richest people to have dinner with them and talk about the spirit of giving. At first, only a few people accepted their invitation. It seemed some of the invited guests were afraid that Buffett and Gates were going to pressure them into giving their wealth to charity.A lot of people are angry at the billionaires who are not willing to give away their fortunes. They criticize them for being miserly and not caring about the poor and the less fortunate. But I think this criticism is wrong. A gift, any gift, should come from the heart. Instead of criticism, these reluctant billionaires should be encouraged to follow the examples of Yu Pengnian and Chen Guangbiao. Encouragement is always a better strategy than criticism.

的取值范围;若不存在,请说明理由.【分析】(1)当n≥2时通过2a n﹣S n=1与2a n﹣1﹣S n﹣1=1作差,进而计算可得结论;(2)通过(1)可得T n的表达式,进而计算即得结论;(3)通过(1)可知数列{c n}的通项公式,利用并项相加、分n为奇数、偶数两种情况讨论即可.【解答】(1)证明:∵2a n﹣S n=1,﹣S n﹣1=1,∴当n≥2时,2a n﹣1两式相减,整理得:a n=2a n﹣1(n≥2),又∵2a1﹣S1=1,即a1=1,∴数列{a n}是首项为1、公比为2的等比数列,∴a n=2n﹣1;(2)解:∵T n=(1+2+22+…+2n﹣1)(1+2+22+…+2n﹣1)=•=4n﹣2•2n+1,∴==1;(3)结论:存在这样的实数t,使得对于所有的n都有成立.理由如下:由(1)可知,1+b n=3log2a n=3n﹣3,即b n=3n﹣4,b n+1=3n﹣1,故c n=(﹣1)n+1b n•b n+1=(﹣1)n+1(3n﹣4)(3n﹣1),c n+1=(﹣1)n+2(3n﹣1)(3n+2),特别地,当n为奇数时,有n+1为偶数,此时c n+c n+1=(3n﹣4)(3n﹣1)﹣(3n﹣1)(3n+2)=﹣6(3n﹣1),①若n为偶数,则C n=(c1+c2)+(c3+c4)+…+(c n﹣1+c n)=﹣6×[2+8+…+(3n﹣4)]=﹣n(3n﹣2),由可知t≤﹣(3﹣)对所有正偶数n都成立,故t≤﹣;②若n为奇数,则C n=C n﹣1+c n(n≥2),由①可知C n=﹣(n﹣1)(3n﹣5)+(3n﹣4)(3n﹣1)=n2﹣3n﹣,其中C1=﹣2满足上式;由①②可得实数t的取值范围是:t≤﹣,所以存在这样的实数t,使得对于所有的n都有成立.【点评】本题是一道关于数列与不等式的综合题,考查分类讨论的思想,考查运算求解能力,注意解题方法的积累,属于中档题.21.(18分)已知集合M是满足下列性质的函数f(x)的全体,存在实数a、k (k≠0),对于定义域内的任意x均有f(a+x)=kf(a﹣x)成立,称数对(a,k)为函数f(x)的“伴随数对”(1)判断f(x)=x2是否属于集合M,并说明理由;(2)若函数f(x)=sinx∈M,求满足条件的函数f(x)的所有“伴随数对”;(3)若(1,1),(2,﹣1)都是函数f(x)的“伴随数对”,当1≤x<2时,;当x=2时,f(x)=0.求当2014≤x≤2016时,函数y=f(x)的零点.【分析】(1)由题意可得(a+x)2=k(a﹣x)2,化为(1﹣k)x2+2a(1+k)x+(1﹣k)a2=0对x∈R成立,需满足条件,解方程即可判断;(2)哟题意可得sin(a+x)=ksin(a﹣x),运用两角和差公式,化简结合余弦函数的值域即可得到所求数对;(3)由(1,1)和(2,﹣1)都是函数f(x)的“伴随数对”,所以f(1+x)=f (1﹣x)且f(2+x)=﹣f(2﹣x),可得f(x)为周期为4的函数,求得0<x <1,1<x<2,2<x<3,3<x<4,x=0,1,2,3,4的函数解析式,可得2014<x<2015,2015<x<2016,x=2014,2015,2016的解析式,即可得到所求零点.解:(1)由f(x)=x2及f(a+x)=kf(a﹣x),可得(a+x)2=k(a﹣x)2,即为(1﹣k)x2+2a(1+k)x+(1﹣k)a2=0对x∈R成立,需满足条件,解得,故k=1≠0,a存在,所以f(x)=x2∈M.(2)由f(x)=sinx∈M得:sin(a+x)=ksin(a﹣x),sinacosx+cosasinx=k(sinacosx﹣cosasinx),所以(1+k)cosasinx+(1﹣k)sinacosx=0,sin(x+φ)=0对任意的x∈R都成立,只有k2+2kcos2a+1=0,即cos2a=﹣(k+),由于|k+|≥2(当且仅当k=±1时,等号成立),所以|cos2a|≥1,又因为|cos2a|≤1,故|cos2a|=1.其中k=1时,cos2a=﹣1,a=nπ+,n∈Z;k=﹣1时,cos2a=1,a=nπ,n∈Z.故函数f(x)的“伴随数对”为(nπ+,1)和(nπ,﹣1),n∈Z.(3)因为(1,1)和(2,﹣1)都是函数f(x)的“伴随数对”,所以f(1+x)=f(1﹣x)且f(2+x)=﹣f(2﹣x),于是f(x+4)=f(x),故函数f(x)是以4为周期的函数.若0<x<1,则1<2﹣x<2,此时f(x)=f(2﹣x)=﹣cos(x),若2<x<3,则1<4﹣x<2,此时f(x)=﹣f(4﹣x)=﹣cos(x),若3<x<4,则0<4﹣x<1,此时f(x)=﹣f(4﹣x)=cos(x),f(x)=故f(x)=当2014≤x≤2016时,函数f(x)的零点分别为2014,2015,2016.【点评】本题考查新定义的理解和运用,考查函数的性质和运用,主要考查函数的周期性和函数的解析式的求法,函数的零点的求法,考查运算能力,属于中档题.。

Each word can only beGerman school teacher, who felt that there was a need for overnight accommodation for his students in order that they could see new things and have new experiences outside the 1 .He felt that one learns by observing, and tried to make his dream come true in the year 1909, when he started providing accommodation for his students in inns, farmhouses and the like.The first youth hostel was opened in Schirrmann’s own school in Altena, after which it was 2 by a permanent hostel in Altena Castle. Schirrmann went on to 3 the German Youth Hostel Association in the year 1919. By this time, the idea of the youth hostel had 4 far and wide, all over the lands of Europe and further.And then, in the year 1932, a(n) 5 organization called the International Youth Hostel was founded in Amsterdam, which consisted of youth hostels from Switzerland, Germany, Poland, the Netherlands, Norway, Britain, Ireland, France, Czechoslovakia, Denmark and Belgium. Richard Schirrmann became its chairman in 1933.The idea of the youth hostel is for young people who are on nature trips to get 6 accommodation in exchange for some money and a helping hand with the domestic chores(家务活). These hostels were said to build character and a sense of independence, as the youth who stayed in them got the 7 to see how other people lived as well as to help to do work.Youth hostels are also places to meet and make new friends. They have no class 8 and everyone has to do their share. Here, wealth and position does not help you gain 9 , but friendliness does. The friendlier you are, the more you learn from the 10 of staying in a youth hostel.II.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.AYu Pengnian is an 88-year-old real estate Chinese businessman. He amassed a fortune of $1.3 billion dollars during his career but instead of keeping the money and living like an emperor, he decided to give it all away. All of his fortune will be spent on helping poor Chinese students get a better education.And Yu isn’t the only super-rich person in China who has this spirit of giving. Chen Guangbiao, a Jiangsu recycling tycoon, has given millions of dollars to charity and promises to give all of his money to charity when he dies.Yu and Chen are among the many businessmen who have become prosperous during China’s economic rise. An American business magazine, Forbes, estimates that there are 117 billionaires in China and hundreds of thousands of millionaires. What sets Yu and Chen apart from the rest, though, is their tremendous generosity when it comes to donating money to charity.Last week Bill Gates and Warren Buffett came to Beijing. Gates and Buffett, two of the world’s richest men, are also the world’s biggest philanthropists. They invited fifty of China’s richest people to have dinner with them and talk about the spirit of giving. At first, only a few people accepted their invitation. It seemed some of the invited guests were afraid that Buffett and Gates were going to pressure them into giving their wealth to charity.A lot of people are angry at the billionaires who are not willing to give away their fortunes. They criticize them for being miserly and not caring about the poor and the less fortunate. But I think this criticism is wrong. A gift, any gift, should come from the heart. Instead of criticism, these reluctant billionaires should be encouraged to follow the examples of Yu Pengnian and Chen Guangbiao. Encouragement is always a better strategy than criticism. As we say in English, “You can catch more flies with honey than with vinegar.”1.He amassed a fortune of $1.3 billion dollars during his career… The word “amassed” means ______.A.stimulatedB. contemplatedC. immigratedD. accumulated2.Yu Pengnian will spend all of his fortune in _______ A. helping poor Chinese students get a better educationB.helping the students in earthquake-stricken areaC.helping his off-springs lead a rich life in the futureD.achieve his aim of living like an emperor3.According to the passage, which of the following statements is TRUE?A.Yu Pengnian is the only super-rich person in China who has the spirit of giving.B.Chen Guangbiao is a real estate Chinese businessman.C.Yu and Chen become wealth during the rise of China’s economy.D.When Bill Gates and Warren Buffett invited fifty of China’s richest people to have dinnerwith them, they all felt honored and accepted their invitation at once.4.What sets Yu and Chen apart from other rich people in China? A. When it comes to charity work, they are very generous.B.They had dinner with Bill Gates and Warren Buffett, talking about the spirit of giving.C.They are pressured into giving their fortune to charity.D.They are both businessmen.5.According to passage, why does the author end the passage with the English saying “You can catch more flies with honey than with vinegar”?A.The author wants to tell us that flies prefer honey to vinegar.B.The author wants to prove that encouragement is always a better strategy than criticismwhen it comes to charity.C.The English saying expresses the main theme of the passage.D.The author wants to criticize those billionaires who are not willing to give away theirfortunes for being miserly and not caring about the poor and the less fortunate.BAaron Carter isn’t like other 12-year-olds. He doesn’t go to school, and he’s already got a job. He is a big pop star. A few years ago he started his singing with Crazy Little Party Girl, which became a hit at once. Now he goes around the world and his songs are in the tops.Because he’s traveling around all the time Aaron doesn’t have to go to school, but don’t envy him too much---- he still has to do lessons and homework. And he is good at learning.“I have to fit my schoolwork around my singing,” he explains. “But I’m lucky because I have a private tutor who travels with me. I sometimes have to have lessons on a plane. That’s really interesting!”Aaron’s favorite subject is math but he hates history. He knows clearly that having a good singing career doesn’t mean he can go without schoolwork.“It would be easy to think that I don’t need to do well in exams, but that would be crazy,” he says. “It’s important to get my qualifications(资格) so that I have something to fall back on. Besides, it’s interesting to learn about other people and cultures.”Aaron’s favorite type of music is rock’n’roll. “The best thing about being a singer” he says, “is that you get to travel all around the world. But the worst thing is that you’re away from home so much that you don’t get to see your friends or family.”6.According to the passage, we learn that Aaron Carter is__________.A.a composerB. a successful singerC. a history loverD. a young businessman7.Which of the following statements is True?A.Aaron Carter doesn’t go to school because he likes singing better.B.Aaron Carter has his own teacher.C.Aaron likes math as well as history.D.Aaron Carter likes traveling all around the world and dislikes seeing friends and family.8.The underlined phrase “fall back on” in the fifth paragraph has the similar meaning as________.A.check inB. return toC. depend onD. decide on第 II 卷I.

杨浦高级中学2018-2019学年高三第一学期英语摸底考试II. Grammar and VocabularySection ADirections: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.Mbappe, who was born on 20 December 1998, is technically still on loan at Paris St-Germain from Monaco but (21) (expect) to join the French champions for 180m euros (£165.7) as the second (22) (expensive) player of all time. Only the 200m euros (£177m) PSG paid for Brazil forward Neymar in 2017 surpasses that fee. It is not just searing pace Mbappe is blessed with but sublime skill, quick thinking, two clever feet, a cool head, bravery, belief and a brutal eye for goal. His two finishes were predatory, low and powerful. What’s more, He is fast. This requires some clarification: most professional soccer players are fast, in the sense (23) they move more quickly than the average person. Some are fast in a more impressive sense, (24)they move more quickly than the average professional soccer player. It was an incredible performance from a centre forward (25) has the lot: blistering pace, goals, touch and technique.“At 19, to put in a performance like that, (26) millions watching and Messi at the other end, it was simply brilliant.” Mbappe, from the suburbs of Paris, only made his international debut last year. His rise to the top has been dizzying (27) he burst on to the scene in the 2016-17 season, scoring 26 goals in 44 games as Monaco (28) (reach) the Champions League semi-finals and won Ligue 1.His two goals here utterly wiped out Argentina’s gathering momentum and announced his supreme talent to the world. Not since 1958, (29) the legendary Brazilian Pele, then 17, found the net twice against Sweden in the final, has a teenager scored twice in a World Cup game.“I’m very happy, and it’s amazing (30) (compare) to a great player like Pele but he’s in another category,” Mbappe said. “Still, it’s great to join the list of players that have achieved such feats.”【答案】21. is expected 22. most expensive 23. that 24. in that 25. that/who26. with 27. since 28. reached 29. when 30. to be compared【解析】21. 并列句,考查谓语动词。
