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.

Plants will emit an increased amount of heat when they are______________.

A. sprayed with pesticides          

B. facing an infrared scanner

C. in poor physical condition        

D. exposed to excessive sun rays

In order to apply pesticide spraying precisely, we can use infrared scanning to____________.

A. estimate the damage to the crops  

B. measure the size of the affected area

C. draw a color-coded map         

D. locate the problem area

Farmers can save a considerable amount of pesticide by______________.

A. resorting to spot-spraying       

B. consulting infrared scanning experts

C. transforming poisoned rain      

D. detecting crop problems at an early stage

The application of infrared scanning technology to agriculture met with some difficulties

_______________.

A. the lack of official support      

B. its high cost

C. the lack of financial support      

D. its failure to help increase production

Infrared scanning technology may be brought back into operation because of_____________.

  A. the desire of farmers to improve the quality of their produce

  B. growing concern about the excessive use of pesticides on crops

  C. the forceful promotion by the Department of Agriculture

  D. full support from agricultural experts                  

Even plants 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.

Some Chinese new - rich like eating shark fin soup because they think it shows their class. However, for the Chinese NBA idol Yao Ming, doing so is unacceptable as the practice has led to the overfishing of sharks.
When Yao and his wife Ye Li got married in 2007, they publicly announced that they would not allow shark fin soup to be served at their wedding banquet.
Actually, Yao had been saying no to shark fins since 2006, when he was appointed as the Goodwill Ambassador for wild life protection.
Now, the 226 - cm big guy is resorting to his personal influence to encourage more to say no to eating the soup and to raise awareness of protecting animals. “Sharks are friends of human beings. They are not our food,” Yao said.
Other celebrity athletes like Olympic champions. Li Ning and Kong Linghui are following on the heels of Yao, throwing themselves into serving the public as Goodwill Ambassadors for wild animal rescue. Recent reports about Yao’s retirement have saddened tens of thousands of basketball fans both at home and abroad. Yet Yao's influence goes far beyond the basketball courts.
Yao has engaged himself in charity and public welfare services for quite a while. When the devastating 8.0 -magnitude earthquake hit Wenchuan in southwest China in 2008 , Yao donated 2 million yuan. “When I was a little boy, my parents and teachers told me to help others and to be a good man,” Yao recalled. “But I could nor donate then because I had not much pocket money. After I moved to Houston, I got involved in quite a number of community service activities and I felt a strong sense of achievement when I got people together,”Yao said.
Like Yao, newly crowned French Open champion Li Na has showed her willingness to donate. Li gave 480,000 yuan of her prize money from the open, plus 20,000 yuan from her own pocket, to a local nursing home in her hometown. Another Chinese sports icon, hurdler Liu Xiang, has also been actively involved in charity for years.
【小题1】The reason why some Chinese new-rich like eating shark fin soup is that they think            

A.it is very deliciousB.it is very cheap and healthy
C.it is very popular in societyD.it can show their status
【小题2】Yao Ming is against eating shark fin soup because              
A.too many sharks are killedB.he dislikes eating sharp fin
C.it is too expensiveD.sharks are dangerous animals
