10、n is the organ of the body in the head. It controls our bodys functions, movements, emotions and thoughts. But a brain can mean so much more.A brain can also simply be a smart person. If a person is called brainy, he is smart and intelligent. If afamily has many children but one of them is super sma
11、rt, you could say, “Hes the brains in the family.” And if you are the brains behind something, you are responsible for developing or organizing something. For example, Bill Gates is the brains behind Microsoft.Brain trust is a group of experts who give advice. Word experts say the phrase “brain trus
12、t” became popularwhen Franklin D. Roosevelt first ran for president in 1932. Several professors gave him advice on social and political issues facing the U.S. These professors were called his “brain trust”.These ways we use the word “brain” all make sense. But other ways we use the word are not so e
13、asy tounderstand. For example, to understand the next brain expression, you first need to know the word “drain”. As a verb, to drain means to remove something by letting it flow away. So a brain drain may sound like a disease where the brain flows out the ears. But, brain drain is when a countrys mo
14、st educated people leave their countries to live in another. The brains are, sort of, draining out of the country.However, if people are responsible for a great idea, you could say they brainstormed it. Here, brainstorm isnot an act of weather. It is a process of thinking creatively about a complex
15、topic. For example, business leaders may use brainstorming to create new products, and government leaders may brainstorm to solve problems.If people are brainwashed, it does not mean their brains are nice and clean. To brainwash means to makesome accept new beliefs by using repeated pressure in a fo
16、rceful or tricky way. Keep in mind that brainwash is never used in a positive way.21. According to the text, if youre the CEO of Baidu you can be called .A. the organ of Bai Du B. the brain drain of Bai DuC. the brains behind Bai Du D. Bai Dus brain trust22. Roosevelt successfully won the election p
17、robably because .A. he got his brain trust B. he got the help of word expertsC. he was smart at giving advice D. he was the brains behind America23. From the passage, we can infer that .A. to drain a lake means to fill it with a lot of waterB. brainy and brainwash are never used in a negative wayC.
18、brainstorming is not a good choice for a political leader for lack of creativityD. a country suffers a “brain drain” when educated people move to other countriesBWhen I was seven my father gave me a Timex, my first watch. I loved it, wore it for years, and havent had another one since it stopped tic
19、king a decade ago. Why? Because I dont need one. I have a mobile phone and Im always near someone with an iPod or something like that. All these devices tell the time which is why, if you look around, youll see lots of empty wrists; sales of watches to young adults have been going down since2007.But
20、 while the wise have realized that they dont need them, others apparently including some distinguished men of our time are spending total fortunes on them. Brands such as Rolex, Patek Philippe and Breitling command shocking prices, up to 250,000 for a piece.This is ridiculous. Expensive cars go fast
21、er than cheap cars. Expensive clothes hang better than cheapclothes. But these days all watches tell the time as well as all other watches. Expensive watches come with extra functions but who needs them? How often do you dive to 300 meters into the sea or need to find your direction in the area arou
22、nd the South Pole? So why pay that much of five years school fees for watches that allow you to do these things?If justice were done, the Swiss watch industry should have closed down when the Japanese discovered howto make accurate watches for a five-pound note. Instead, the Swiss reinvented the wat
23、ch, with the aid of millions of pounds worth of advertising, as a message about the man wearing it. Rolexes are for those who spend their weekends climbing icy mountains; a Patek Philippe is for one from a rich or noble family; a Breitling suggests you like to pilot planes across the world.Watches a
24、re now classified as “investments”. A 1994 Philippe recently sold for nearly 350,000, while1960s Rolexes have gone from 15,000 to 30,000 plus in a year. But a watch is not an investment. Its a toy for self-satisfaction, a matter of fashion. Prices may keep going up theyve been rising for 15 years. B
25、ut when fashion moves on, the owner of the 350,000 beauty will suddenly find his pride and joy is no more a good investment than my childhood Timex.24. The sales of watches to young people have fallen because they_.A. have other devices to tell the time B. think watches too expensiveC. prefer to wea
26、r an iPod D. have no sense of time25. It seems ridiculous to the writer that_.A. people dive 300 meters into the seaB. expensive clothes sell better than cheap onesC. cheap cars dont run as fast as expensive onesD. expensive watches with unnecessary functions still sell26. What can be learnt about S
27、wiss watch industry from the passage?A. It targets rich people as its potential customersB. Its hard for the industry to beat its competitorsC. It wastes a huge amount of money in advertisingD. Its easy for the industry to reinvent cheap watches27. Which would be the best title for the passage?A. Ti
28、mex or Rolex? B. My Childhood TimexC. Watches? Not for Me! D. Watches a Valuable CollectionC“I moved him,” the old man said. “I moved him then.” He felt faint again now but he held on the great fishall the strength that he could. I moved him, he thought. Maybe this time I can get him over. Pull, han
29、ds, he thought. Hold up, legs. Last for me, head. Last for me. You never went. This time Ill pull him over.But when he put all of his effort on, starting it well out before the fish came alongside and pulling with allhis strength, the fish pulled part way over and then righted himself and swam away.
30、“Fish,” the old man said. “Fish, you are going to have to die anyway. Do you have to kill me too?”That way nothing is accomplished, he thought. His mouth was too dry to speak but he could not reach forthe water now. I must get him alongside this time, he thought. I am not good for many more turns. Y
31、es, you are, he told himself. Youre good for ever.On the next turn, he nearly had him. But again the fish righted himself and swam slowly away. You arekilling me, fish, the old man thought. But you have a right to. Never have I seen a greater, or more beautiful, or a calmer or more noble thing than
32、you, brother. Come on and kill me. I do not care who kills who.Now you are getting confused in the head, he thought. You must keep your head clear. Keep your headclear and know how to suffer like a man. Or a fish, he thought.“Clear up, head,” he said in a voice he could hardly hear. “Clear up.”Twice
33、 more it was the same on the turns.I do not know, the old man thought. He had been on the point of feeling himself go each time. I do not know. But I will try it once more. He tried it once more and he felt himself going when he turned the fish. The fish righted himself and swam off again slowly wit
34、h the great tail heaving in the air.Ill try it again, the old man promised, although his hands were mushy now and he could only see well inflashes. He tried it again and it was the same. So he thought, and he felt himself going before he started; I will try it once again. The old man dropped the lin
35、e and put his foot on it and lifted the harpoon (鱼叉) as high as he could and drove it down with all his strength, and more strength he had just summoned (召集), into the fishsside just behind the great chest fin that rose high in the air to the altitude of the mans chest. He felt the iron goin and he
36、leaned on it and drove it further and then pushed all his weight after it.Then the fish came alive, with his death in him, and rose high out of the water showing all his great lengthand width and all his power and his beauty. He seemed to hang in the air above the old man in the skiff. Then he fell
37、into the water with a crash that sent spray (喷) over the old man and over all of the skiff.28. Why did the old man keep talking to himself while fighting against the fish?A. To rescue himself from great pressure. B. To remind himself of the hidden danger.C. To prevent himself from feeling tired. D.
38、To give himself constant encouragement.29. Which of the following statements is true about the fisherman?A. The fisherman seemed to be playing a cat-and-mouse game with the fish.B. The fisherman showed respect for the fish in this fierce battle.C. The fisherman has been fighting with the fish for lo
39、ng, which made him anxious.D. The fisherman, experienced as he was in fishing, nearly got killed on several occasions.30. What can be inferred from the sentence “Fish, you are going to have to die anyway”(Para. 3) ?A. Quite a few fishermen were chasing and hunting the fish.B. The fish had been serio
40、usly injured and couldnt live long.C. The old man had much confidence in catching the fish.D. As a matter of fact, the fish was too old to live any longer.31. Which of the following words best describes the old man?A. Ambitious. B. Aggressive. C. Strong-willed. D. Sympathetic.DWhy should mankind exp
41、lore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.Perhaps the best answer lies
42、in our genetic makeup as human beings. What drove our ancestors to movefrom the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand
43、 wherever possible.Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areascan be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.Exploration also allows minerals a
44、nd other potential resources to be found. Even if we have no immediateneed of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the l
45、ength or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems.Even non-stick pans and mirrored sunglasses are by-products (副产品) of technological developments in thespa
46、ce industry!While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it
47、 also holds dangers. The danger exists, but knowledge can help human beings to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.While Earth is the only planet known to support life, surely the adaptive ability of humans would allow usto live on oth
48、er planets. It is true that the lifestyle would be different, but human life cultures have adapted in the past and surely could in the future.32. What is the reason for exploring space based on Paragraph 2?A. Humans are nature-born to do so. B. Humans have the tendency to fight.C. Humans may find ne
49、w sources of food. D. Humans dont like to stay in the same place.33. The underlined word “spin-offs” in Paragraph 4 probably refers to _.A. survival chances B. potential resourcesC. unexpected benefits D. physical possessions34. What makes it possible for humans to live on other planets?A. Our genet
50、ic makeup B. Resources on the earthC. The adaptive ability of humans D. By-products in space exploration35. Which of the statements can best sum up the passage?A. Space exploration has created many wonders.B. Space exploration provides the best value for money.C. Space exploration can benefit scienc
51、e and technology.D. Space exploration may help us avoid potential problems on Earth.第三节 从短文后的选项中选出能填入空白处的最佳选项。（每小题 2分，满分 10分）Learning how to use new words well will make it easier to learn a language and make you more knowledgeable.36 If youre committed to building your vocabulary, set a goal for yo
