For the first time in history, evolution has taken a backseat. There is an ongoing realization that human beings are capable of directly shaping their own evolution. As we case into the twenty-first century, we realize that genetic engineering is undoubtedly going to have a dramatic【C1】______on our lives. It seems that with genetic engineering, science has moved from【C2】______the natural world to redesigning it. Now we must ask ourselves【C3】______this influence will be for better or for worse. However, scientists remain【C4】______in their opinions. Some have【C5】______against the hazards of genetic engineering,【C6】______others have dismissed these perils as inconsequential. Lewis Wolpert, professor of biology at University College London, says, "There are no ethical【C7】______because you are not doing any【C8】______to anyone." And the gist of his statement is staunchly supported by James Watson, a Nobel Prize winner. "If we can make better human beings by knowing how to change【C9】______, why shouldn’t we do it?" They are both extremely【C10】______of excuses that genetic engineering is a bad idea.【C11】______, two other prominent scientists have【C12】______their displeasure about genetic engineering. They have made no【C13】______of the rather strong and true feelings【C14】______genetic engineering. George Wald, Nobel Prize winning biologist wrote recombinant DNA technology【C15】______our society with unprecedented problems in the history of science. It places in human hands the【C16】______to redesign living organisms, the【C17】______of some three billion years of evolution. It is happening too fast. It【C18】______probably the largest ethical problem, for going【C19】______in this direction may be not only unwise but【C20】______.
【C11】
选项
A、With contrast
B、In contrast
C、On contrast
D、For contrast
答案
B
解析
固定搭配题。后文列举了两位持相反观点的科学家对基因工程的不满,与前文形成对比。in contrast的意思是“相反”,用在文章中引出截然相反的两种观点,所以应该选B)。
