1.（2010·湖北卷·T22）

After the earthquake, the first thing the local government did was to provide

for the homeless families.

A. accommodation

B. occupation

C. equipment

D. furniture.

【解析】选D。512的汶川地震，414玉树地震。天灾“earthquake”相信是很多考生都准备过的一个话题。所以相关词汇“accommodation”表示“住处”应该是考生们准备的系列词汇之一。这道题难度不大

，句子结构也相对

简单。只要背过这几个词，知道“occupation”表示“占用”或者“工作，职业”；“furniture”表示“

家具

”；“equipment”表示“设备，器材”就能选出正确答案D了。

2.（2010·湖南卷·T26）

Dina,

for months to find a job as a waitress, finally took a position at a local advertising agency. A. struggling

B. struggled

C. having struggled

D. to struggle

【解析】选C。考查非谓语动词。该空，分词短语作时间状语，其逻辑主语Dina与struggle为主动关系，故排除B项。由剧中的finally可知非谓语动词表示的动作发生在句中谓语took a position之前，故用现在分词的完成主动式。

could be life' s most important decision -- marriage -- almost entirely up to luck. A. as

B. that

An Italian philosopher once said that a great man makes his own good luck. What he means is that when good luck comes, a great man knows how to seize the opportunity and

36

advantage of it. There is a story about Bill Gates, the

37

44

no one home, wasn’t sure what to do, but he didn’t want to waste his trip, so he stopped by Gates’ house to ask him if he knew anything about the inventor’s system and

45

it worked. Since Gates was working on very

46

software, most other people in his place would have spoken

47

with the executive, told him that he was working on something else, and then forgotten about the whole thing. Gates, however, saw a（n）

48

and jumped on it. He told the executive that

49

he was working on his own operating system（he wasn’t）and he would be

50

to discuss it with the executive in a few weeks. After the executive

51

to a meeting to be held a few weeks later, Gates quickly went out

52

for someone who had a workable new operating system. As an engineer he had a better idea than the executive about what he needed, and when he found someone with an operating system that he liked, he made modifications（修改）

on what the executive told him. His meeting a few weeks later was a great

A An apple a day may poison children. Children who eat an apple or a pear a day may be exceeding（超过）the pesticide（杀虫剂）safety limit because of remains on the fruit, according to research.

The research, published on Sunday, says the government repeatedly claims that the levels of pesticide are safe because, instead of measuring individual apples, researchers buy 10, crush them and take an average reading to see if they are safe. This is the internationally agreed method of checking remains. But government figures show that the pesticide is not averagely spread across the batch（一批）, and one or two apples could contain 90% or more of the pesticide in the batch. It used mathematical modeling to measure exposure to pesticides for children aged between 18 months and four years old. The pesticides involved can destroy children’s hormones and some are suspected of causing cancer. The good news for British fruit growers is that samples（抽样）grown in this country had lower residue

level than imported fruit, so buying home-produced fruit will reduce the danger, said Emily Diaman, one of the Earth’s senior food researchers and one of the authors of the report.

56. The reason why “An apple a day may poison children” is that __________. A. there are some harmful insects or worms in the apple B. children would get a poisonous level of pesticides because of the remains on the apple C. there are always more pesticides on the apples

produced in Britain D. the apple is too hard for children to eat 57. According to the passage, the internationally agreed method of checking remains __________. A. tells exactly the pesticide level of each apple B. works well only with British fruits C. can’t tell whether a specific apple is safe to eat or not D. used mathematical modeling to measure exposure to pesticides for children. 58. The underlined word “residue” can be replaced by

__________.

A. remains

B. pesticide

C. poison

D. medicine 59. Which of the following is NOT true？

A. The remains of the pesticides can do harm to the children’s health.

B. The remains of the pesticides can do harm to the children’s hormones.

C. Some remains of the pesticides are suspected of causing cancer. D. For safety, we’d better not eat apples from Britain. 第

B Do you know who invented the slide-fastener, or rather, the zipper（拉链）? No one thought of anything like the zipper until Whitcomb Judson came along. Judson’s slide-fastener was an out-of-blue invention. No one knows what gave him the idea. No one even knows much about him, except that he was a mechanical engineer living in Chicago and that he patented other inventions to do with a street railway system and motorcars. Judson invented the first zipper in 1891. This ingenious little device looks very simple, and the principle behind it is simple, too; yet it took a lot of years, together with another inventor to make the zipper really practical. The zipper had to be produced cheaply, because no one would pay a lot of money for it. Judson invented a machine to mass-produce his slide-fastener. But the machine was terribly complicated and kept on breaking down. So in 1905 Judson invented a new fastener, the C-curity, which was easier to manufacture. Clothing manufacturers, however, were not the least bit interested in trying out the fasteners, so the only way Judson could get them on to the market was by letting pedlars（小贩）

sell them from door to door. Moreover, the C-curity fastener was clumsy and had a bad habit of bursting open at inconvenient times. Then a young Swedish engineer called Sundback came to work for Judson’s struggling company. He thought hard and decided that the interlocking parts needed to be much smaller to give the fastener greater flexibility and to stop it bursting open. After several attempts, Sundback invented a really practical fastener in 1913. It is in all important ways the same as the one we use today. Clothing manufacturers still refused to use the fastener. But in 1918 an inventor showed the American army a flying suit he had invented. It happened to use the slide-fastener. The army put the suit through such tough tests that it disintegrated(分裂)---all except the fastener! A Navy officer happened to see the tests, and Judson’s unknown little company got an order for ten thousand fasteners. Later, Judson’s invention was used in the manufacture of rubber galoshes（橡胶套鞋）

by a big company. They called the galoshes `Zippers´. This is how the slide-fastener got it s popular name. 60. What does the sentence “Whitcomb Judson’s slide-fastener was called an out-of-blue 第
