Key James, Secretary of Health and Human Resources in the Virginia State government, loves to turn the tables on those who don't think it's possible to be middle-class,conservative,educated and still be truly black. Once, during an Abortion debate, a woman in the audience angrily told James she was so middle-class she didn't have a clue about real African American life. "If you understood what these women go through," the woman said, "you would realize that abortion is their only choice. "

　　James then asked the woman to consider a poor black mother on welfare. She already has four children and an alcoholic husband who has all but abandoned the family. Now she discovers another child is on the way. How would you counsel that woman, asked James.

　　"Have an abortion," the woman responded. "That child would have a very poor quality of life. "

　　"I have a vested interest in your answer," James said. "The woman I described was my mother. I was the fifth of six children born into poverty. And, in case you're interested,the quality of my life is just fine!"

　　Passage Four

　　Even plants can run a fever, especially when they're under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3,000 feet away--straight up. A decade ago, adapting 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, 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-code map showing where plants were running" fevers". Farmers could then spot-spray, using 50 to70 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 Agricultrue, thinks re- mote 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.
