问题    Even plants can run a fever, especially when they are under attack by insects or disease.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 Depart ment 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、put up with
B、came up to
C、came up with
D、stood up to
答案C
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Ccame up with正确。选项Aput up with表示“忍耐，忍受”；选项 Bcome up to表示“达到标准，等于”；选项Dstand up to表示“勇敢地抵抗”。
