问题     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.
选项 A、remote
B、lonely
C、removed
D、desolate
答案A
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”。全句可译为：最近刚从农业部退休的雷·杰克逊认为，远红外技术在这个10年末能被人们所采用。
