Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting 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-coded map showing where plants were running“fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 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 remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.

Do you find getting up in the morning so difficult that it's painful? This might be called laziness, but Dr．Kleitman has a new explanation．He has proved that everyone has a daily energy cycle．
During the hours when you labor through your work you may say that you're “hot”．That's true．The time of day when you feel most energetic is when your cycle of body temperature is at its peak（高峰）．For some people the peak comes before noon．For others it comes in the afternoon or evening．No one has discovered why this is so, but it leads to such familiar monologues （ 自言自语 ） as: “Get up, John! You'll be late for work again!” The possible explanation to the trouble is that John is at his temperature-and- energy peak in the evening．Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has．
You can't change your energy cycle, but you can learn to make your life fit it better．Habit can help, Dr．Kleitman believes．Maybe you're sleepy in the evening but feel you must stay up late anyway．Counteract （ 对抗 ） your cycle to some extent by habitually staying up later than you want to．If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour．This won't change your cycle, but you'll get up steam （ 鼓起干劲 ） and work better at your low point．
Get off to a slow start which saves your energy．Get up with a leisurely yawn and stretch．Sit on the edge of the bed a minute before putting your feet on the floor．Avoid the troublesome search for clean clothes by laying them out the night before．Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours．
1.If a person finds getting up early a problem, most probably________．
A．he is a lazy person
B．he refuses to follow his own energy cycle
C．he is not sure when his energy is low

A．Getting off to work with a minimum effort helps save one's energy．
B．Dr．Kleitman explains why people reach their peaks at different hours of day．

D．Children have energy cycles, too．
