Even plants can run a fever, especially

{{/U}}humans, plants can have their temperature{{U}} (72) {{/U}}from

physicist Stephen Paley{{U}} (74) {{/U}}a quick way to take the
temperature of crops to determine{{U}} (75) {{/U}}ones are under stress.
The goal was to let farmers{{U}} (76) {{/U}}target pesticide spraying{{U}}
(77) {{/U}}rain poison on a whole field, which{{U}} (78)
{{/U}}includes plants that don't have the pest problem. Even
better, Paley's Remote Scanning Services Company could detect crop problem

showing{{U}} (82) {{/U}}plants were running "fevers". Farmers could then

【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。
