Passage Five
Even plants can run a fever, especially when they’re under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago, adapting the infrared (红外线) scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂) spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest (害虫) problems.
Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-code map showing where plants were running" fevers".
A. the lack of official support
B. its high cost
C. its failure to help increase production
D. the lack of financial support
Even plants can run a fever, especially
when they’ re under attack by insects or disease. But unlike humans, plants can
have their temperature taken from 3 000 feet away—straight up. A decade ago,
adapting the infrared(红外线)scanning technology developed for military purposes
and other satelities, physicist Stephen Paley came up with a quick way to take
the temperature of crops to determine which ones were under stress. The goal was
to let farmers precisely target pesticide(杀虫剂)spraying rather than rain poison
on a whole field, which invariably includes plants that don’t have
pest(害虫)problems. Even better, Paley’ s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed int A. estimate the damage to the crops B. draw a color-coded map C. measure the size of the affected area D. locate the problem area 我来回答: 提交
