A

【导学号：34410042】Even plants can run a fever，especially when they're under attack by insects or disease.But unlike humans，plants can have their temperatures taken from 3,000 feet away—straight up.A decade ago，adopting the infrared(红外线的) scanning technology developed for military purposes and other satellites，physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress.The goal was to let farmers precisely target pesticide(杀虫剂)spraying rather than rain poison on a whole field，which invariably includes plants that don't have pest problems.

Even better，Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye.Mounted on a plane flown at 3,000 feet at night，an infrared scanner measured the heat emitted by crops.The data were transformed into a color-coded map showing where plants were running “fevers”．Farmers could then spot-spray，using 50 to 70 percent less pesticide than they otherwise would.

The bad news is that Paley's company closed down in 1984, after only three years.Farmers resisted the new technology and long-term backers were hard to find.But with the renewed concern about pesticide on produce, and refinements in infrared scanning，Paley hopes to get back into operation.Agriculture experts have no doubt the technology works.“This technique can be used on 75 percent of agricultural land in the United States，”says George Oerther of Texas A&M.Ray Jackson，who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade.But only if Paley finds the financial backing which he failed to obtain 10 years ago.

【语篇解读】植物也会生病发烧，科技也可以用于农业中为植物诊断疾病。

1．Plants will send out an increased amount of heat when they are________.

A．facing an infrared scanner

B．sprayed with pesticide

C．in poor physical condition

D．exposed to excessive sunrays

【解析】细节理解题。由文章第二段“...an infrared scanner measured the heat emitt ed by crops.The data were transformed into a color-coded map showing where plants were running ‘fevers’．”可知，植物在发“高烧”，也就是说，植物在“身体状况”不佳时才会散发出更多的热。

【答案】 C

2．In order to apply pesticide spraying precisely，we can use infrared scanning to________.

A．estimate the damage to the crops

B．draw a color-coded map

C．measure the size of the affected area

D．locate the problem area

【解析】推理判断题。由文章第二段末尾“...showing where plants were running‘fevers’．Farmers could then spot-spray...”可知，用红外线扫描的目的是确定有问题的区域，以使农民有针对性地喷杀虫剂。

【答案】 D

3．Farmers can save a considerable amount of pesticide by________.

A．resorting to spot-spraying

B．transforming poisoned rain

C．consulting infrared scanning experts

D．detecting crop problems at an early stage

【解析】细节理解题。由文章第二段最后一句“Farmers could then spot-spray，using 50 to 70 percent less pesticide than they otherwise would.”(采取点喷，农民们可以节省平时用量的50%至70%的杀虫剂)可知。

【答案】 A

B

In China，many people are leaving the countryside to find jobs in the cities，because the countryside is much poorer than the city，and often there isn't much work there.Services such as hospital and transport are usually much better in the city than in the countryside.They hope that their lives will improve when they move to the city.

But in the big cities of Europe like London or Paris，people are moving out of the city.These rich families want to live a quieter life.They are tired of the noise

and the dirt of the city，and they are tired of the crowded streets，crowded trains and buses.They don't want to live in the cities any more.They want a house with a garden in the countryside，and breathe the fresh air there.

So they move out of the cities.Some don't go very far，just to the towns near the cities.Other people move to the real countryside with sheep, cows and green fields.There，they start new lives and try to make new friends.

Not all those who move from the city to the countryside are happy.After two or three years，many people who have done this feel that it was a big mistake.They don't make so much money and there isn't much work to do.People in the countryside are very different and aren't always very friendly.

As a result，quite a lot of people who have moved to the countryside move back to the city.“It's_wonderful_to_see_crowds_in_the_streets_and_cinema_lights，”they say.

【语篇解读】久居农村，城市是一道风景；久居城市，农村又是另一道风景。本文重点介绍了农村和城市的优缺点。

4．Which is NOT the reason for people moving to the cities in China?

A．The countryside is much poorer than the city.

B．People in the countryside have nothing to eat.

C．People in the countryside don't have much work to do there.

D．Services in cities are usually much better than those in the countryside.

【解析】细节理解题。根据第一段中的“because the countryside is much poorer than the city，and often there isn't much work there.Services such as hospital and transport are usually much better in the cit y than in the countryside.”可知乡村比城市贫穷，而且工作机会少，像医疗和交通等服务比城市差，故B项符合题意。

【答案】 B

5．After moving to the countryside，some people in Europe feel unhappy because________.

A．they can't make much money

B．there isn't much work for them to do in the countryside

C．some people in the countryside aren't always very friendly to them
