Major companies are already in pursuit of commercial applications of the new biology.
They dream of placing enzymes in the automobile to monitor exhaust and send data on pollution to a microprocessor that will then adjust the engine. They speak of what the New York Times calls "metal-hungry microbes that might be used to mine valuable trace metals from ocean water". They have already demanded and won the right to patent new life forms.
Nervous critics, including many scientists, worry that there is corporate, national, international, and inter-scientific rivalry in the entire biotechnological field. They create images not of oil spills, but of "microbe spills" that could spread disease and destroy entire populations. The creation and accidental release of extremely poisonous microbes, however, is only one cause for alarm. Completely rational and respectable scientists are talking about possibilities that stagger the imagination.
Should we breed people with cow-like stomachs so they can digest grass and hay, thereby relieving the food problem by modifying us to eat lower down on the food chain? Should we biologically alter workers to fit the job requirement, for example, creating pilots with faster reaction times or assembly-line workers designed to do our monotonous work for us? Should we attempt to eliminate "inferior" people and breed a "super race"?( Hitler tried this, but without the genetic weaponry that may soon issue from our laboratories.) Should we produce soldiers to do our fighting? Should we use genetic forecasting to pre-eliminate unfit babies? Should we grow reserve organs for ourselves, each of us having, as it were, a "savings bank" full of spare kidney, livers, or hands?
Wild as these notions may sound every one has its advocates (and opposers) in the scientific community as well as its striking commercial application.
As two critics of genetic engineering, Jeremy Rifkin and Ted Howard, stale in their book Who Should Play Goal "Broad scale genetic engineering will probably be introduced to America much the same way as assembly lines, automobiles, vaccines, computers and all the other technologies. As each new genetic advance becomes commercially practical, a new consumer need will be exploited and a market for the new technology will be created."
According to the passage, the exhaust from a car engine could probably be checked by________.
选项
A、using metal-hungry microbes
B、making use of enzymes
C、adjusting the engine
D、patenting new life forms
答案
B
解析
本题为细节题,“the exhaust from a car engine could probably be checked by…”(意思是:汽车发动机的尾气可以通过…来检测。)就是定位词,在原文中第二段开头They dream of placing enzymes in the automobile to monitor exhaust and send data on pollution to a microprocessor that will then adjust the engine;其中check与monitor都是检测的意思,是同义替换词;意思是:他们梦想把酶(催化剂)放入车辆内来检测汽车尾气,并把关于污染的数据发送给会调节发动机的微处理器。与各选项对比,A“运用需求金属的微生物”;B“充分利用酶”;C“调节发动机”;D“为新生活形式申请专利”;所以可以看出“酶enzymes“可能用来检测汽车尾气,因此本题选B。
