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."
According to the passage, which of the following would worry the critics the most?

选项 A、The unanticipated explosion of population.
B、The creation of biological solar cells.
C、The accidental spill of oil.
D、The unexpected release of destructive microbes.

答案D

解析 本题为细节题,题干中“worry the critics the most”就是定位词;在原文中第三段中Nervous critics,including many scientists,worry that there is corporate,national,international and inter-scientific rivalry in the entire biotechnological field.再把各选项的中心词在原文中定位;A“意料之外的人口大爆发”;population在原文中“destroy entire populations”意思是:破坏整个人口,所以A与原文不符。B“biological solar cells”意思是:生物太阳能电池,在原文中没有出现。C中的spill of oil“石油泄露”,D中的the unexpected release of destructive microbes“破坏性的微生物的出乎意料的排放“release“释放,发布”与spill“泄漏,排放”是同义替换词,在原文中;not of oil spills,but of“microbe spills”以及“accidental release of extremely poisonous microbes”,说明否定oil spills,肯定microbe spills,且accidental“偶然的”与unexpected“出乎意料的”是同义替换词;还有poisonous“有毒的”与destructive“破坏性的”是同义替换词。所以排除C,D与原文中既有原词也有同义替换词,这是最佳答案;因此本题选D。
