| 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. 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(***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 emitted by crops. The data were transformed into a colourcoded map showing where plants were running "fevers". Farmers could then spotspray, 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 longterm 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. 1. 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 2. In order to apply pesticide spraying precisely, we can use infrared scanning to________. A. estimate the damage to the crops B. draw a colourcoded map C. measure the size of the affected area D. locate the problem area 3. Farmers can save a considerable amount of pesticide by________. A. resorting to spotspraying B. transforming poisoned rain C. consulting infrared scanning experts D. detecting crop problems at an early stage | ||||||||||||||||||||||||

| Nuclearpowered aircraft carriers are considered one of the most important marine weapons in the 20th century. So far, only two countries in the world, the USA and France, have ever produced them. But these fearful fighting machines are about to enter Asia. The US Navy said last month that one of its nine nuclearpowered aircraft carriers will be sent to Japan to replace the diesel(柴油)powered carrier Kitty Hawk in 2008. In an agreement on October 30, the two countries also planned to level up their military (军事的) cooperation and the USA called for Japan to take a larger role in alliance military moves. It will be the first time that a nuclearpowered carrier is based in Japan. Bombed by US forces in World War ? at Hiroshima and Nagasaki, Japan is the only world country to have been attacked by a nuclear weapon. Therefore, the citizens are highly sensitive to where nuclearpowered weapons are based. "A radiation leak at Yokosuka would kill 100,000 people as far away as Tokyo, and could cause billions of dollars in damage," said Masahiko Goto, leader of a protest group in Yokosuka. His group has collected more than 300,000 signatures of people across Japan opposed to the nuclear carrier. The 44yearold Kitty Hawk, the US Navy"s oldest active ship, has been based in Yokosuka since 1998. It had returned to the US to be decommissioned in 2008. The new carrier, yet to be unveiled,_ will travel faster, be capable of supporting longer operations and carry with it the Navy"s most modern technology. Experts pointed that this change is not only to strengthen the USJapan military alliance but also to keep the military power of China and North Korea within limits. However, even Japanese experts don"t believe that the two countries are threats to the region. "There is no need for Japan to have a nuclear carrier as defense," said Tetsuo Maeda, an international relations professor at Tokyo International University. He said that the change of ship indicates an increased military capability in the region, much more than what is needed. 1. With such a formidable weapon to enter its country, Japanese citizens ________. A. are aware of its benefits to the country B. are anxious about its potential danger C. are curious about the advanced technology D. are against where the carrier will be based 2. The replacement of the aircraft carrier is intended to________. A. set up a kind of base in Japan B. strengthen the USJapan military alliance C. show Japan"s greater military capability D. get rid of the dated marine weapon 3. From the story, we learn that________. A. no other countries except the USA and France possess aircraft carriers B. Japan has long planned to increase its military capability with new weapons C. Japan will be the first country in Asia to have a nuclear aircraft carrier D. Japan will be the third country to produce a nuclearpowered aircraft carrier 4. The underlined word "unveiled" in the fifth paragraph probably means________. A. perfected B. discussed about C. produced D. brought to view | ||||||||||||||||||||||||
