2、ped 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

3、includes plants that dont have pest (害虫)problems.Even better, Paleys 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 i

27、题。依据文章第二段“.an infrared scanner measured the heat emitted by crops.The data were transformed into a colorcoded map showing where plants were runningfevers”可知，植物“身体状况”不佳(发烧)时才会散发热，所以选项C符合题意。2D推理判断题。本题要求判断使用红外线扫描技术的方式。依据文章第二段“.showing where plants were running feversFarmers could then spotspray，”说明目的是确

28、定有问题的区域，以使农民有针对性地喷杀虫剂。显然，选项D(确定有问题的地域)为最佳选项。3A细节理解题。依据文章第二段最后一句“Farmers could then spotspray, using 50 to 70 percent less pesticide than they otherwise would”(采取点喷，农民可以节省平时用量的50%至70%的杀虫剂)，选项A符合题意。4C推理判断题。依据文章第三段的第一句“The bad news is that Paleys company closed down in 1984, after only three years.Farm

29、ers resisted the new technology and longterm backers were hard to find”，可以看出红外线扫描技术应用于农业遇到了一些问题，原因有两个：一是农民对新技术的抵制，二是难以找到长期赞助商。文章中还有一处明显的提示出现在最后一句：“But only if Paley finds the financial backing which he failed to obtain 10 years ago”从该句提供的信息同样可以反推出10年前的情形，所以选项C正确。5B细节理解题。依据文章第三段“But with the renewed

30、concern about pesticides on produce, and refinements in infrared scanning，Paley hopes to get back into operation.”可知B项(出于对杀虫剂过度使用的担心)符合题意。(二)【文章大意】 本文为说明文，主要介绍威尼斯引以为豪的古建筑正承受着来自人类与大自然的双重威胁。1D逻辑推理题。根据第一段“but in Venice very nearly everything is remarkable, from the magnificent Piazza San Marco (St.Mark
