问题    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 God?,"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."
Which of the following notions is NOT mentioned?
选项 A、Developing a"savings bank" of ones organs.
B、Breeding soldiers for a war.
C、Producing people with cow-like stomachs
D、Using genetic forecasting to cure diseases
答案D
解析 本题为细节题，本题的定位词在各选项中；A“developing a savings bank of one’s organs”意思是：培养一个某人自己的器官库；在原文第四段中Should we grow reserve organs for ourselves，each of us having，as it were，a“savings bank”full of spare kidney, livers，or hands?出现了，所以排除A；B“breeding soldiers for a war”意思是：为战争培养士兵；Should we produce soldiers to do our fighting?选项中的breed“培育，产生”与原文中produce“生产，制造”属于同义替换词，选项中war“战争”与原文中fighting“战斗”属于同义替换词，因此该选项在原文中存在，排除B；C“producing people with cow-like stomachs”意思是：制造出有类牛胃口的人们；在原文第四段的第一句：Should we breed people with cow-like stomachs，所以C还是在原文中存在，排除C；D“using genetic forecasting to cure disease”意思是：利用基因预测来治疗疾病。在原文中Should we use genetic forecasting to pre-eliminate“unfit”babies?意思是：我们应该利用基因预测来预筛‘不健康的’婴儿；选项的意思与原文不符，所以D不存在；因此本题选D。
