问题     Even plants can run a fever, especially when they are under attack by insects or disease. But (1)_____ humans, plants can have their temperature (2)_____ from 3,000 feet away—straight up. A decade ago, (3)_____ the infrared scanning technology developed for military purpose and other satellites, physicist Stephen Paley (4)_____ a quick way to take the temperature of crops to determine (5)_____ ones are under stress. The goal was to let farmer (6)_____ target pesticide spraying (7)_____ rain poison on a whole field, which (8)_____ include plants that don’t have the pest problem.
    Even better, Paley’s Remote Scanning Services Company could detect crop problem before they became (9)_____ to the eye. Mounted on a plane flown at 3,000 fee (10)_____, an infrared scanner measured the heat emitted by crops. The data were (11)_____ into a color-coded map showing (12)_____ plants were running "fevers". Farmers could then spot spray, using 50 to 70 percent less pesticide than they (13)_____ would.
    The bad news is that Paley’s company closed down in 1984, after only three years. Farmers (14)_____ the new technology and long-term backers were hard (15)_____. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to (16)_____ into operation. Agriculture experts have no doubt about the technology works. "This technique can be used (17)_____ 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 (18)_____ infrared crop scanning could be adopted by the end of the decade. But (19)_____ Paley finds the financial backing (20)_____ he failed to obtain 10 years ago.

选项 A、precisely
B、extraordinarily
C、exceedingly
D、extremely
答案A
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precisely正确。选项extraordinary表示"格外地"，选项exceedingly表示"非常地；极度地"，选项extremely表示"极端地"，均不符合题意。
