【答案解析】此属于语法题，have one's temperature taken表示“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。
全句可译为：不过，与人不同的是，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】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。
【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。
【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。
【答案解析】此题属于语篇衔接。otherwise表示“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。
全句可译为：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%。
