Even plants can run a fever, especially when they are under attack by insects or disease. But (1) humans, plants can have their temperature (2) from 3,000 feet away—straight up. A decade ago, (3) the infrared scanning technology developed for military purpose and other satellites, physicist Stephen Paley (4) a quick way to take the temperature of crops to determine (5) ones are under stress. The goal was to let farmer (6) target pesticide spraying (7) rain poison on a whole field, which (8) include plants that don't have the pest problem. Even better, Paley's Remote Scanning Services Company could detect crop problem before they became (9) to the eye. Mounted on a plane flown at 3,000 feet (10) , an infrared scanner measured the heat emitted by crops. The data were (11) into a color-coded map showing (12) plants were running "fevers". Farmers could then spot spray, using 50 to 70 percent less pesticide than they (13) would. The bad news is that Paley's company closed down in 1984, after only three years. Farmers (14) the new technology and long-term backers were hard (15) . But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to (16) into operation. Agriculture experts have no doubt about the technology works. "This technique can be used (17) 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 (18) infrared crop scanning could be adopted by the end of the decade. But (19) Paley finds the financial backing (20) he failed to obtain 10 years ago.
【答案解析】此题属于语意搭配题。adopt表示“采纳,收养,接受”,如:adopt a method/suggestions。该处需要一个动词与宾语the infrared scanning technology搭配,且此处应填动名词,故选项[B]adopting正确。选项[C]adapt表示“使适应”,常与介词to/for连用,例如:adapt oneself to hot weather。
单选题
[A] put up with [B] came up to [C] came up with [D] stood up to
【正确答案】
C
【答案解析】此题属于语意搭配题。come up with表示“想出(计划、答案、回答)”,如:He couldn't come up with an answer when I asked him why he was late.原句需要与宾语a quick way搭配的短语动词,故选项[C] came up with正确。选项[A]put up with表示“忍耐,忍受”;选项[B]come up to表示“达到标准,等于”;选项[D]stand up to表示“勇敢地抵抗”。
【答案解析】此题属于语意搭配题。precisely表示“准确地,精确地”,根据下文“target pesticide spraying...rain poison on a whole field”可知,利用红外扫描技术是给“患病”庄稼定位,从而有利于定点施治,故选项[A] precisely正确。选项[B]extraordinary表示“格外地”,选项[C]exceedingly表示“非常地;极度地”,选项 [D]extremely表示“极端地”,均不符合题意。
单选题
[A] more than [B] less than [C] rather than [D] other than
【正确答案】
C
【答案解析】此题属于语篇衔接题。rather than表示“而不是”,根据句意,其目的是为了让农民准确地定点喷洒农药,从而与在整块田上洒农药作对比,选择前者,放弃后者,故选项[C] rather than正确。其他选项:[A]more than和[B]less than都是指量的多少,[D]other than意为“except,anything but”,均与句意不符。
单选题
