Fill in each blank with the word or phrase that best fits the context.By the end of the 20th century, TV show producers had begun to turn to the cheapest performers available —their audience. It seemed that anyone who wanted fame could 25 it. And some people wanted it far too much.Richard and Mayumi Heene, 26 , launched a large balloon 2,000 meters into the air and then called a TV network to say that their six-year-old son, Falcon, was inside it. Planes were re-routed and Denver International Airport was briefly __27 . However, Falcon was later found to have been hiding in the family’s garage the whole time. The “balloon boy” incident turned out to be a hoax ( 骗局) and the Heenes were 28 of doing it in the hope of landing their own reality TV shows. Instead, they got a fine and a short sentence each — but they were certainly29 for a while.So do we want fame? Research suggests that a large number of us do. According to one recent survey, 30 percent of adults regularly daydream about being famous and 40 percent of us expect to 30 some kind of fame in our lifetimes. Perhaps a better question is: should we want to be famous? Do we really want every 31 of our private lives exposed in newspapers and discussed on television? Some people, such as talent show contestant Susan Boyle, seem ill-euipped to deal with this kind of 32 , despite their talent. Boyle gained international fame for her extraordinary singing voice after appearing on TV talent show Britain’s Got Talent and her first album became the fastest-selling of all time in the U.K. But the sudden fame didn’t seem easy for her at first, and after the final of the show, Boyle was 33 to a private psychiatric clinic.Furthermore, people who achieve fame often don’t seem to like it once they have it. A survey of celebrities found that they worry about the press, critics, threatening letters, the lack of privacy, and the 34 on their children. These are hardly worries that 35 people have to deal with. They also, 36 , worry about what would happen if they were no longer famous. And there are plenty of people to ask about that. Take, for example, Donato Dalrymple, a fisherman who rescued a boy from the sea and enjoyed the media spotlight for several months afterwards. When it ended, however, he 37 his job as a toilet cleaner. “I know I’m a nobody,” he said when the attention had 38 .“When the person has to go back to everyday life, there’s a sense of 39 , loss and being cheated out of something,” says Dr. Robert Cancro of the New York University School of Medicine.25.A. envy B. avoid C. afford D. get26.A. for example B. on the other handC. in contrastD. in comparison27.A. shut down B. searched throughC. sent offD. looked into28.A. charged B. accused C. considered D. warned29.A. supported B. ashamed C. crazy D. famous30.A. involve B. increase C. beat D. experience31.A. arrangement B. aspect C. variety D. zone32.A. behavior B. crisis C. pressure D. reputation33.A. accessible B. admitted C. used D. crowded34.A. weight B. influence C. benefit D. energy35.A. intelligent B. well-known C. common D. considerate36.A. accidentally B. fortunately C. ironically D. understandably37. A. held up B. gave up C. decided on D. returned to38. A. disappeared B. arisen C. been paid D. grown39. A. moderation B. achievement C. disappointment D. directionSection BDirections: Read the following three passages. 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.(A)My father died when I was nine, and I remember doing the household chores to help my mother.I hated changing the vacuum cleaner (真空吸尘器) bag and picking up things the machine did not suck up.Twenty years later, in 1978, I was doing chores at home alongside my wife. One day the vacuum cleaner was screaming away, and I had to empty the bag because I could not find a replacement for it. With this lifelong hatred of the way the machine worked, I decided to make a bagless vacuum cleaner.Easier said than done, of course. I didn’t realize that I would spend the next five years perfecting my design, a process that resulted in 5,127 different prototypes (设计原型). By the time I made my 15th prototype, my third child was born. By 2,627, my wife and I were really counting our pennies. By 3,727, my wife was giving art lessons for some extra cash, and we were getting further and further into debt. These were tough times, but each failure brought me closer to solving the problem.I just had a passion for the vacuum cleaner as a product, but I never thought of going into a business with it. In the early 1980s, I started trying to get licensing agreements (许可协议) for my technology. The reality was very different, however. The major vacuum makers had built a business model based on the profits from bags and filters (滤网). No one would license my idea, not because it was a bad one, but because it was bad for business.That gave me the courage to keep going, but soon after, the companies that I had talked with started making machines like mine. I had to fight legal battles on both sides of the Atlantic to protect the patents on my vacuum cleaner. However, I was still in financial difficulties until 1993, when my bank manager personally persuaded Lloyds Bank to lend me $1 million. Then I was able to go into production. Within two years, the Dyson vacuum cleaner became a best-seller in Britain.Today, I still embrace risk and the potential for failure as part of the process. Nothing beats the excitement of invention. Go out and brainstorm your ideas. You are not bound to any rules — in fact, the stranger and riskier your idea, the better.40.According to the article, which of the following statements about James Dyson is NOT true?his mother.customers as soon as it arrived on the market.41.According to the article, Dyson’s bagless vacuum cleaner was produced in large numbersin the early 1980slend him $1 million42.It can be inferred from the article that .confidence in his vacuum cleaner initially43.According to the article, which of the following would most likely be Dyson’s motto?A.We are all failures — at least the best of us are.B.The foundation stones for a success are honesty, faith, love and loyalty.C.It is only in adventure that some people succeed in knowing themselves.D.The brave man is not he who does not feel afraid, but he who conquers that fear.(B)Shakespeare’s Globe Exhibitio n & Tour is a unique international resource to explore Shakespeare’s work.

The old man is snoring (打鼾). He bumped his head when he went to bed, and he couldn’t get up in the morning.” Why couldn’t the old man in the children’s song get up? (Let’s kindly suppose that he just didn’t want to get up.) This was possi bly because in the absence of sunlight, the body was still producing the hormone melatonin (褪黑素), which makes people sleepy.There are many ways that rainfall affects human behavior. But how much does rain really affect people’s moods and behavior?In 2008, researchers from the University of Minnesota and Lanzhou University published a paper. They proposed that decreased rainfall was influential in social upheaval (社会动荡) and the downfall of the Tang, Yuan and Ming dynasties in ancient China. This is thought to be related to reduced rice cultivation.But how might rain affect social behavior in the modern world? A 2009 New York Times investigation found that murder rates in New York drop significantly on rainy days. Meanwhile, in Britain, Dr. Peter Langmead-Jones of Greater Manchester police published a study in 2015 detailing an analysis of 6.6 million police records over one decade in Manchester. “The research showed that the heavier the rainfall, the lower the recorded crime,” he said.Langmead-Jones also found that there is a strong association between heavy rain and relatively few violent crimes recorded including domestic abuse. This might be because heavy rainstops people from going out to buy alcohol and the reduced alcohol consumption results in fewer crimes.It’s not all good news though. One study in 1997 concluded that the behavior of children can predict oncoming storms — they were observed to exhibit their worst behavior when barometric pressure (气压) fell. Another study in 2012 found that women are much more likely to be affected psychologically by rain and that they report much lower levels of life satisfaction than men on rainy days.For all the complaints about rain, it does have some characteristics that hold broad appeal. The sound of raindrops can be very comforting and often features in sleep-inducing relaxation apps. The theory behind this is that the pitter-patter of raindrops is a form of “pink noise.” It can decrease brain activity and consequently improves the quality of sleep. So if it’s raining where you are, the best thing to do may be to have a nap.47.The author uses the lyrics of a song in the first paragraph to .A.introduce the interesting song to readersB.voice his understanding of why the old man couldn’t get up in the morningC.illustrate one way that wet weather influences human behaviorD.explain why people often get up late on rainy days48.According to Dr. Peter Langmead-Jones, relatively few crimes are recorded on rainy days because .A.p eople prefer to take a nap at home when it’s rainingB.m ost people are depressed on rainy daysC.p eople are too lazy to go out when it’s rainingD.a lcohol consumption is reduced due to wet weather49.According to the article, the influences that rainy days have on human behavior include.①decreased grain output②relatively few criminal records③higher chance of feeling low in spirits④more possibility of feeling sleepyA.①②③B.①②④C.①③④D.②③④50.According to the last paragraph, what’s the positive impact of rain on human behavior?A.The sound of raindrops helps people sleep better.B.On rainy days, all people can get more sleep.C.It offers a good chance to listen to relaxing music.D.People feel more satisfied with themselves when it’s raining.Section CDirections: Complete the following passage by using the sentences in the box. Each sentence can only be used once. Note that there are two sentences more than you need.A.Every year, millions of people are murdered by these two killers.B.Gene technology can help people to give birth to healthy and clever children.C.Doctors can cure cancer and heart disease with the help of gene technlogy.D.Many people, however, are worried that gene technology can be used to manufacture human beings in large quantities.E.Sometimes it is a hot topic discussed by people.Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. 51 .The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing about, such as cancer and heart disease. 52 . And to date, doctors have not found an effective way to cure them. But if gene technology is applied, not only can these two diseases be cured completely, bringing happiness and more living days to patients, but the great amount of money people spend on treating their diseases can also be saved, therefore it benefits the economy as well. In addition, human life spans (寿命) can beprolonged.53 . Some families, with the English imperial family being a good example, have hereditary ( 遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem. The scientist just needs to find the wrong gene and correct it, and a healthy child will be born.54 . In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babieswill not come out in large quantities, for most couples in the world can have babies in a very normal way. Of course, the government must take care to regulate gene technology.语法选择1-4 C B A D5-14 A A D B B D C D A C小猫钓鱼15-24 G C K D I F B H J E完型25-39 DAABD DBCBB CCDAC阅读40-43 BDBC44-46 B C D47-50 C D D A六选四51-54 EABD。
