1、科普类考题1)(nmet 典型例题 in 1901,h.g.wells, an english writer,wrote a book describing a trip to the moon. when the explorers (探险者) landed on the moon, they discovered that the moon was full of un- derground cities. they expressed their surprise to the "moon people" they met. in turn, the "mo

2、on people" expressed their surprise. "why," they asked, "are you traveling to outer space when you don't even use your inner space?"h.g.wells could only imagine travel to the moon. in 1969, human beings really did land on the moon. people today know that there are no und

3、erground cities on the moon. however, the question that the "moon people" asked is still an interesting one. a growing number of scien- tists are seriously thinking about it.underground systems are already in place. many cities have underground car parks. in some cities, such as tokyo, seo

4、ul and montreal, there are large underground shopping areas. the "channel", a tunnel (隧道) connecting england and france, is now complete.but what about underground cities? japan's taisei corporation is designing a network of un- derground systems, called "alice cities". the d

5、esigners imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. a solar dome (太阳能穹顶) would cover the whole city. supporters of underground development say that building down rather than building up is a good way to use the earth's space.

6、 the surface, they say, can be used for farms, parks, gar- dens, and wilderness. h.g. wells' "moon people" would agree. would you? 1. the explorers in h.g.wells' story were surprised to find that the "moon people" . a. knew so much about the earth b. understood their lang

7、uage c. lived in so many underground cities d. were ahead of them in space technology 2. what does the underlined word "it" (paragraph 2) refer to? a. discovering the moon's inner space. b. using the earth's inner space. c. meeting the "moon people" again. d. traveling to

8、 outer space. 3. what sort of underground systems are already here with us? a. offices, shopping areas, power stations. b. tunnels, car parks, shopping areas. c. gardens, car parks, power stations. d. tunnels, gardens, offices. 4. what would be the best title for the text? a. alice cities-cities of

9、the future. b. space travel with h.g.wells. c. enjoy living underground. d. building down, not up.解析1c此题考查考生对事实细节的判断能力。文中第一段when the explorer landcd on the moon， theythey expressedto the moon peoplc they met， 2b此题测试考生根据上下文信息推断代词含义的能力。解这道题首先要搞清楚it指代文章第一段中“moon people问explorers的问题：why are you travelin

10、g to outer space whenyoudon't even use your inner space?然后根据问题的内容判断出正确答案为b项。 3b这是一个细节理解题。文章的第三段中是这样描述的：many cities have undergroundcarparks直至段尾，提供了相关信息，由此推断出正确答案为b项。 4d此题考查考生在理解全文的根底上对文章主旨的概括能力。本文描写的是“moon people遇到explorers所问的问题引发人们的思考：why not use our inner space?以及人们已开始这方面的探索、实践，故d项building dow

11、n，not up最为贴切地概括了人们一开始的想法(up)以及现在的观点(down)。考题2(nmet 典型例题 london (reuters)organic fruit, delivered right to the doorstep. that is what gabriel gold prefers, and he is willing to pay for it. if this is not possible, the 26-year-old computer technician will spend the extra money at the supermarket to bu

12、y organic food. "organic produce is always better," gold said. "the food is free of pesticides (农药), and you are generally supporting family farms instead of large farms. and more often than not it is lo cally (本地) grown and seasonal, so it is more tasty." gold is one of a growin

13、g number of shop- pers buying into the organic trend, and supermarkets across britain are counting on more like him as they grow their organic food business. but how many shoppers really know what they are get- ting, and why are they willing to pay a higher price for organic produce? market research

14、 shows that gold and others who buy organic food can generally give clear reasons for their preferences but their knowledge of organic food is far from complete. for example, small amounts of pesticides can be used on organic products. and about three quarters of organic food in britain is not local

15、 but imported (进口) to meet growing demand. "the demand for organic food is increasing by about one third every year, so it is a very fast-growing market," said sue flock, a specialist in this line of business.1. more and more people in britain are buying organic food because . a. they are

16、getting richer b. they can get the food anywhere c. they consider the food free of pollution d. they like home-grown fruit 2. which of the following statements is true to the facts about most organic products sold in britain? a. it grows indoors all year round. b. it is produced outside britain. c.

17、it is grown on family farms. d. it is produced on large farms. 3. what is the meaning of "the organic trend" as the words are used in the text? a. growing interest in organic food. b. better quality of organic food. c. rising market for organic food. d. higher prices of organic food. 4. wh

18、at is the best title for this news story? a. organic food-healthy, or just for the wealthy? b. the making of organic food in britain. c. organic food-to import or not? d. good qualities of organic food.解析 1c此题考查考生根据文中信息进行分析推理的能力。文中第二段中gold said，“thefood is free of pesticides，由此可以看出c项是正确的。a项they are

19、getting richer中richer的说法是不正确的。文中第一段提到的delivered right to the door step是一种方式，atthesupermarkettobuyorganicfood是另一种方式，但并非随处可以买到，故b项中anywhere的说法没有依据。d项中的fruit不够全面，因为文中屡次出现food，而不仅仅是 fruit。2b此题考查考生综合信息推理判断的能力。文中没有信息支持a项中indoors的说法。文中提到四分之三的“绿色食品是imported(进口的)，由此得出结论：b项是正确的。c项的说法是一些人的不正确的看法，因为文章的第二段中but t

20、heir knowledge of organic food is far from complete说明了局部人的观点是片面的、不全面的。文章中也没有提供信息说明organic food are produced on large farms。3a此题主要检测考生是否能够根据特定语境猜想词语的能力。四个选项分别涉及：a项的growing interest是指人们对“绿色食品越来越感兴趣，形成一种潮流。b项的better quality of organic food与buy into前后搭配在一起是不妥的，如换用buying for thebetter qualityoforganicfoo

21、d较好；c项的risingmarket“不断扩大的市场是“消费人群增长的 结果，而非原因；d项的higherprice，“绿色食品的消费群不断增长不可能是因为“越来越高的价格。4a此题考查考生在理解全文的根底上对文章主旨的概括能力。本段新闻报道主要介绍人们对绿色食品的越来越大的兴趣。一方面它是free of pesticides，即healthy；一方面价格比拟高，故a项中两种信息都涉及了，为最正确选项。b项中“在英国的绿色食品生产，在文中没有作详细介绍，不是重点。c项的import(进口)与否也不是人们关注的焦点。文章也没有对绿色食品的优点作具体的介绍，故也不恰当。考题3(典型例题，c) l

35、th enamel. they studied the enamel for the carbon-13. animals that eat grasses have higher carbon-13 levels than those eating fruits and other plants. what they found was that the teeth of the hominids had an in-between amount of carbon-13, which meant not only they were eating fruits, they were eat

36、ing a lot of grass, or animals eating grasses. the lower carbon-13 levels could also come from eating certain types of insects (昆虫).but there are people who understand differently. prof. ungar of the university of arkansas agrees the study offers new suggestions of hominid diet, but disagrees about

44、ious yeasts (酵母) that caused the fermentation (发酵) process. pasteur discovered that heating the wine gently for a few minutes after it had fer- mented would kill off the yeast that was left in the wine, with the result that the wine would re- main fresh for much longer. he also proved that food and

45、drinks could be turned bad by other or- ganisms that were present in the air, and that they too would keep fresh much longer if they were kept in airtight containers.the heating process was so successful that it made pasteur famous. it was named "pasteurization'' in his honour, and by a
