问题     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】______. [br] 【C5】
选项 A、threatened
B、noticed
C、informed
D、warned
答案 D
解析 动同辨义题。这句的意思是“一些科学家已经警示基因工程的危险”，warn的意思是“警告，告诫”，warn与against经常搭配使用，所以应该选D)。threatened“恐吓”；noticed“注意”；informed“通知”。
