单选题
Even plants can run a fever, especially when they are under attack by insects or disease. But (71) humans, plants can have their temperature (72) from 3,000 feet away—straight up. A decade ago, (73) the infrared (红外线的) scanning technology developed for military purpose and other satellites, physicist Stephen Paley (74) a quick way to take the temperature of crops to determine (75) ones are under stress. The goal was to let farmers (76) target pesticide spraying (77) rain poison on a whole field, which (78) includes plants that don't have the pest problem. Even better, Paley's Remote Scanning Services Company could detect crop problem before they became (79) to the eye. Mounted on a plane flown at 3,000 feet (80) , an infrared scanner measured the heat emitted by crops. The data were (81) . into a color-coded map showing (82) plants were running "fevers". Farmers could then spot spray, using 50 to 70 percent less pesticide than they (83) would. The bad news is that Paley's company closed down in 1984, after only three years. Farmers (84) the new technology and long-term backers were hard (85) . But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to (86) into operation. Agriculture experts have no doubt the technology works. "This technique can be used (87) 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 (88) infrared crop scanning could be adopted by the end of the decade, but (89) Paley finds the financial backing (90) he failed to obtain 10 years ago.
【答案解析】语法题,have one's temperature taken意为“量体温”,其他选项:B take,C took和D taking均不符合被动语态的用法。句意:不过,与人有所不同的是,植物的体温可以从3,000英尺以外的高空测到。
【正确答案】
B
【答案解析】语意搭配题。adopt意为“采纳,收养,接受”,如:adopt a method/suggestions,该处需要一个现在分词与宾语the infrared scanning technology搭配作为句子的状语,故选项B adopting正确。选项C adapt意为“使适应,改编”,常与介词to/for连用,例如:adapt oneself to hot weather,与句意不符。
【正确答案】
C
【答案解析】语意搭配题。come up with意为“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意为“忍耐,忍受”;选项B come up to意为“达到标准,等于”;选项D stand up to意为“勇敢地抵抗”。
【答案解析】语意搭配题。precisely意为“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,故选择表方式的副词,即选项A precisely正确。选项B extraordinary意为“格外地”;选项C exceedingly意为“非常地;极度地”;选项D extremely意为“极端地”;均属程度副词。
【正确答案】
C
【答案解析】语篇衔接题。rather than意为“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做对比,选择前者,放弃后者,故选项C rather than正确。其他选项:A more than,B less than指量的多少;D other than=except, anything but均与句意不符。
【答案解析】语篇衔接。otherwise=differently;in the other way意为“不同地,用别的方法”,如:I hate him and I won't pretend otherwise.我恨他,而且我也不假装。根据原文,定点喷洒农药是采用其他方法所耗农药的50%~70%,所以选项A otherwise正确。其他选项:B still;C thus;D therefore均不符合题意。句意:这样,农民针对病害定点喷洒所耗的农药是采用其他方法所需农药的50%~70%。
【答案解析】语意搭配题。to find不定式,表结果,be+adj.+to do为固定搭配,主动形式表示被动。原句意为:长期的支持者难于找到,故选项C to find正确。选项A to find out意为“找到(抽象的结果)”;选项B to be found不定式的被动形式,此处没必要用此形式;选项D to be found on无此搭配。句意:农民们抗拒这种新技术,长期的支持者很难找到。
【正确答案】
D
【答案解析】语意搭配题。根据上文,佩利公司关门了,但是随着对农产品残留农药的重新关注及红外线扫描技术的改良,佩利自然想重操旧业,因此选项D get back正确。选项A get off意为“下车,出发”;选项B get out意为“出去,秘密泄漏”;选项C get away意为“离开”。句意:不过,随着对农产品残留农药的重新关注,以及远红外扫描技术的改良,佩利希望重操旧业。
【答案解析】语篇衔接,根据文章内容,佩利想重操旧业,遥感技术也得到了专家的认同,但佩利还须取得别人经济上的资助才能实现他的想法,故选项C only if符合题意。选项A even if意为“即使”,引导让步状语从句;选项B if only省略主句的条件句,表示期望和愿望,例如:If only he were with us!如果他和我们在一起该多好呀!选项D though意为“但是”,表示转折关系。
