【題目】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 (紅外線）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 (殺蟲劑）spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest(害蟲）problems.

Even better, Foley's Remote Scanning Services Company could detect crop problems before they became visible to the eyes. 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-terra 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 emit an increased amount of heat when they are __________.

A. sprayed with pesticides

B. facing an infrared scanner

【2】 In order to apply pesticide spraying precisely, we can use infra-red 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

【3】 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

【4】 The application of infrared scanning technology to agriculture met with some difficulties. For example，__________.

A. the lack of official support

B. its high cost

C. the lack of financial support

D. its failure to help increase production

【5】 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

【題目】Computer games have been criticised for quite some time over a whole range of issues. Some people say they are overly violent and encourage violent behaviour particularly in children. Others say that they make children unsociable and are bad for their eyes. Some have even attributed falling standards of literacy and a lack of interest in reading on them. Now, however, it seems that computer games have also become a feminist issue.

Game manufacturers have, for some time, been looking to increase the number of female game players. The vast majority of computer games still sell to a mainly male market. Perhaps this is because the violent nature of many of the games appeals more to males or perhaps because many of the main characters in the games are male. Manufacturers' attempts to produce more female characters increase their share of the female gaming market which has met with serious criticism from many women's groups.

While heroines such as Lara Croft of the Tomb Raider game are seen as providing positive role models of strong women, many believe that the character's unrealistic Barbies are subconsciously setting unattainable standards in the minds of young women. Perhaps a stronger criticism is that although many games now include female characters, their role is often secondary and they support the main, male, action characters within the games. Of course the nature of many of the games remains violent and destructive and this in itself could well continue to put off female gamers.

There are now, however, a number of web sites springing up on the World Wide Web to help women deal with this issue. Sites such as Game Girlz, Women Gamers and Game Gal offer game reviews, articles, discussion forums and even employment opportunities for women interested in becoming part of the rapidly expanding games industry. The games are reviewed by women from a very female perspective. Some rate the games from one to ten across a range of criteria which include the appearance of the female characters, the degree of intelligence attributed to them in the game and even the marketing attitude adopted by the company. The sites are obviously looking for games that move away from the very male dominated and violent nature of the majority of computer games. Many of them review games that are more constructive and developmental. Although the common fantasy themes of knights, witches and goblins（妖精） still exist within these games, the aims are often very different. Instead of destroying opposing armies，the aim of the game can be to make peace with them.

With this increased degree of awareness and involvement from women in the games industry many positive changes could be made that could encourage more women and young girls to become enthusiastic about technology. Perhaps we may even find more male gamers moving away from the traditional violent and destructive games towards the more positive values promoted by these more feminine role models, after all Tomb Raider is still one of the most popular computer games on the market, but perhaps that's too much to ask.

【1】What is paragraph 1 mainly about ?

A. The violence in computer games.

【2】Manufacturers want to produce more female characters in order to _______.

A. increase sales in the male market

A. a film which provides positive role models of strong women

B. a site which helps women to deal with many issues
