    Even plant can run a fever especially when they're under attack by insects or disease But unlike human plants can have their temperature taken from 3000 feet away straight up A decade ago adopting the infrared(红外线) 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(精确的) target pesticide(杀虫剂) spraying rather than rain poison on a whole field which always 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 Fixed on a plane flown at 3000 feet at night an infrared scanner measured the heat sent out by crops The data were transformed into a colorcoded map showing where plants were running "fevers" Farmers could then spotspray using 50 to 70 percent less pesticide that 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 longterm supporters were hard to find But with the renewed concern about pesticides on produce and refinements(改进) in infrared scanning Paley hopes to get back into operation Agriculture experts have no doubt that 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 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 support which he failed to obtain 10years ago

1.Plants will give out an increased amount of heat when they are     

A. facing an infrared scanner

B. sprayed with pesticides

C. exposed to extreme sun rays

D. in poor physical condition

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

A. draw a colorcoded map

B. evaluate the damage to the crops

C. locate the problem area

D. measure the size of the affected area

3.The application of infrared scanning technology to agriculture met with some difficulties of     

A. the lack of official support

B. its high cost

C. the lack of financial support

D. its failure to help increase production

4.Infrared scanning technology may be brought back into operation because of     

A. full support from agricultural experts

B. the forceful promotion by the Department of Agriculture

C. the desire of farmers to improve the quality of their produce

D. growing concern about the over use of pesticides on crops

 

1.D 2.C 3.C 4.D 【解析】 本文是一篇说明文。文章讲述的是植物生病以后温度也会升高,我们可以利用这一点来确定生病植物的具体地点。 1.推理题。根据文章第一段第一句Even plant can run a fever, especially when they're under attack by insects or disease.和第二段第二句Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted (排放,散发,发出) bycrops.可知植物在发烧的时候,会散发出比平时更多的热量。故选D。 2.推理题。根据文章第二段第三句The data were transtormed into a color﹣coded map showing where plants wererunningfevers.可知人们可以使用红外线扫描来确定哪里的植物发烧了,也就是说确定问题区域。故选C。 3.推理题。根据文章最后一句But only if Paley finds the financial backing which he failed to obtain 10 years ago,可知第一次Paley失败主要是因为他没有获得足够的资金支持。故选C。 4.推理题。根据文章最后一段第三句But with the renewed concern about pesticides on produce,and refinements(改良,改进) in infrared scanning,Paley hopes to get back into operation.可知人们现在担心粮食上农药的使用量过高,要减少农药使用,就需要Paley的方法。故选D。

I stood at the edge of the cliff. The wind stung my eyes, cutting into my skin. Dark-feathered birds circled the air, swooping (俯冲) low over the ocean every now and then to catch their dinner. Hundreds of feet below, the deep ocean beat against the rough sandy shore. I took a deep breath, filling my lungs with excitement — and at the same time, fear.

Behind me, I heard the rest of the crew start to mutter. I was here for the shooting of a movie as I was one of the lead actors in the film Dangerous Things, and this scene was right in the middle of the climax (故事的高潮). It was vital that this went right.

The director had talked to me about getting a stunt double (替身演员), but I’d persuaded him that I could handle the dive. I’d taken a diving course a few years ago, and I’d been taking swimming lessons since I was five years old. I had been pretty confident that I could do this — up till now.

Someone called out, “Ceria, you don’t have to do this! Are you sure you want to dive?” It was one of the producers, Callie Evans. I knew I couldn’t turn back now. I couldn’t bear to see the disappointed look on the director’s face when he was told that I couldn’t do it.

At that moment, all my fears and worries broke free. The expectation of adventure and victory seemed to move all the hesitation. I swooped downwards. The air on either side of me cut into my extended arms. I knew that this wonderful feeling of flight would only last a few seconds, yet time seemed to slow down so I could hear the thrilled whoops of my crew and a round of applause that seemed to echo in my pounding ears.

1.At the beginning, how did the author feel about what she was going to do?(No more than 3 words)

2.What does the underlined sentence in Paragraph 2 mean in English?(No more than 15 words)

3.Why was the author that confident in diving?  (No more than 10 words)

4.What was the crew’s reaction while the author was diving down?  (No more than 10 words)

5.How do you like the author? Please explain why.  (No more than 25 words)
