单选题 Even plants can run a fever, especially when they are under attack by insects or diseases. But (21) humans, plants can have their temperature (22) from 3,000 feet away--straight up. A decade ago, (23) the infrared(红外线的)scanning technology developed for military purpose and other satellites, physicist Stephen Paley (24) a quick way to take the temperature of crops to determine (25) ones are under stress. The goal was to let farmer (26) target pesticide spraying (27) rain poison on a whole field, which (28) include plants that don't have the pest problem.
Even better, Paley's Remote Scanning Services Company could detect crop problem before they became (29) to the eye. Mounted on a plane flown at 3,000 feet (30) , an infrared scanner measured the heat emitted by crops. The data were (31) into a color-coded map showing (32) plants were running "fevers". Farmers could then spot spray, using 50 to 70 percent less pesticide than they (33) would.
The bad news is that Paley's company closed down in 1984, after only three years. Farmers (34) the new technology and long-term backers were hard (35) . But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to (36) into operation. Agriculture experts have no doubt the technology works. "This technique can be used (37) 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 (38) infrared crop scanning could be adopted by the end of the decade. But (39) Paley finds the financial backing (40) he failed to obtain 10 years ago.

单选题 A. as B. with C. like D. unlike

单选题 A. taken ]B. take C. took ]D. taking

单选题 A. adopted B. adopting C. adapted D. adapting

【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，故选项[B]adopting正确。选项[C]adapt表示“使适应，改编”，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”。

单选题 A. whose B. which C. what D. where

单选题 A. precisely B. extraordinarily C. exceedingly D. extremely

【正确答案】 A

【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，故选择表方式的副词，即选项[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”；均属程度副词。

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。

单选题 A. dominantly B. deliberately C. accidentally D. invariably

【正确答案】 D

【答案解析】此题属于语意搭配题。invariably表示“不变地，一定地”，根据句意，如果整块田都洒上农药，那些没遭虫害的庄稼不可避免地会受到影响，故选项[D]invariably正确。选项[A]dominantly表示“占优势地”；选项[B]deliberately表示“故意地”；选项[C]accidentally表示“偶然地”；均与句意不符。

单选题 A. seeming B. clear C. apparent D. visible

【正确答案】 D

【答案解析】此题属于语意搭配题。visible表示“看得见的”，根据句意：红外扫描技术可以在人们用肉眼看到病虫害之前就测出哪些庄稼会有问题，故选项[D]visible正确。选项[A]seeming表示“看起来”；选项[B]clear表示“清楚的”；选项[C]apparent表示“显然的，貌似的”。

单选题 A. at night B. for the night C. in night D. over night

单选题 31 A. transmitted B. transferred C. transformed D. transported

【正确答案】 C

【答案解析】此题属于语意搭配题。transform表示“改变，使变形”，根据句意，红外扫描仪记录下的数据被转换成一幅地图，显示出哪里的庄稼在发烧，故选项[C]transformed正确。选项[A]transmit表示“转播”；选项[B]transfer表示“转移，调动，转让”；选项[D]transport表示“运输”。

单选题 A. how B. where C. what D. when

单选题 A. otherwise B. still C. thus D. therefore

【答案解析】此题属于语篇衔接。otherwise=differently；in the other way表示“不同地，用别的方法”，如：I hate him and I won't pretend。otherwise．(=pretend I don't)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。

单选题 A. persisted in B. resisted C. insisted on D. assisted

【正确答案】 B

【答案解析】此题属于语意搭配题。resist表示“抵抗”，如：resist disease，根据句意，农民们抗拒这种新技术是佩利公司关门的原因，故选项[B]resisted正确。选项[A]persist in表示“坚持”；选项[C]insist on表示“坚持，坚决要求”；选项[D]assist sb．in doing/to do表示“帮助，援助某人”。

单选题 A. get off B. get out C. get away D. get back

【正确答案】 D

【答案解析】此题属于语意搭配题。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表示“下车，出发”；选项[B]get out表示“出去，秘密泄漏”；选项[C]get away表示“离开”。

单选题 A. of B. in. C. for D. on

单选题 A. remote B. lonely C. removed D. desolate

【正确答案】 A

【答案解析】此题属于语意搭配题。remote表示“遥远的”，根据文章内容，前面谈到红外线扫描技术是在3，000英尺的高空进行的，因此距离较远，故选项[A]remote正确。选项[B]lonely表示“(人)寂寞的；(地方)偏僻的”；选项[C]removed表示“远离的，分离的”，应与介词from连用；选项[D]desolate表示“无人烟的，荒凉的”。

单选题 A. even if B. if only C. only if D. though

【正确答案】 C

【答案解析】此题属于语篇衔接，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在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表示“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，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表示“但是”，表示转折关系。
