Getting back to the maths lesson, students were waiting to be called．One of those 25 hands was John Doe' s．
"John, come on up and answer the question．" I called．

三、阅读理解
E ven 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. 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 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 sent out by crops. The data were transformed into a colour-coded map showing where plants were running “fevers”. Farmers could then spot-spray（点喷）, using 50 to 70 percent less pesticide than they otherwise would.
The bad ne ws 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 if Paley finds the financial backing which he failed to obtain 10 years ago.
36. Plants will send out an increased amount of heat when they are ______.
A. facing an infrared scanner
B. sprayed with pesticides
C. in poor physical condition
D. exposed to excessive sun rays
37. In order to apply pesticide spraying precisely, we can use infrared scanning to ______.
A. estimate the damage to the crops
B. draw a colour-coded map
C. measure the size of the affected area
D. locate the problem area
38. Farmers can save a considerable amount of pesticide by ______.
A. resorting to spot-spraying
B. transforming poisoned rain
C. consulting infrared scanning experts
D. detecting crop problems at an early stage
39. The application of infrared scanning technology to agriculture met with some
difficulties _______.
A. its high cost
B. the lack of official support
C. the lack of financial support
D. its failure to help increase production
40. Infrared scanning technology may be brought back into operation because of ______.
A. full support from agricultural experts
B. growing concern about the excessive use of pesticides on crops
C. the forceful promotion by the Department of Agriculture
D. the desire of farmers to improve the quality of their produce

话题写作One possible version:
I'm Li Hua from Xinhua Middle School. Now I'd like to share my experience in practicing oral English.
Firstly, I'm always confident and brave. I seize every opportunity to speak, not afraid of making mistakes which may embarrass me. I also find it of great benefit to take part in English corners, where I can make many friends. By talking with them, my oral English has improved a lot. Finally, some English programs like CCTV-9 contribute to the progress in my speaking ability. Through this channel, not only am I kept informed of the current events going on both at home and abroad, I also learn the standard pronunciation and intonation by repeated imitation.
Practice makes perfect, as the saying goes. Our hard work will finally be rewarded.
