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 ease into the twenty- first century, we realize that genetic enginee-ring is undoubtedly going to have a dramatic【B1】on our lives. It seems that with genetic engineering, science has moved from【B2】the natural world to redesigning it. Now we must ask ourselves【B3】this influence will be for better or for worse. However, scientists remain【B4】in their opinions. Some have【B5】against the hazards of genetic engineering,【B6】others have dismissed these perils as inconsequential. Lewis Wolpert, professor of biology at University College London, says, "There are no ethical【B7】because you are not doing any【B8】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【B9】why shouldn’t we do it?" They are both extremely【B10】of excuses that genetic engineering is a bad idea.【B11】, two other prominent scientists have【B12】their displeasure about genetic engineering. They have made no【B13】of the rather strong and true feelings【B14】genetic engineering. George Wald, Nobel Prize winning biologist wrote recombinant DNA technology【B15】our society with unprecedented problems in the history of science. It places in human hands the【B16】to redesign living organisms, the【B17】of some three billion years of evolution. It is happening too fast. It【B18】probably the largest ethical problem, for going【B19】in this direction may be not only unwise but【B20】.
选项
A、defect
B、affect
C、effect
D、infection
答案
C
解析
名词辨义题[考频:38]。这句的意思是“当我们轻松地进入21世纪的时候,我们意识到基因工程将会毫无疑问地对我们的生活产生巨大的影响”,have a dramatic effect on意思是“对……产生强烈的影响”,所以应该选C)。affect作动词的意思是“影响”,作名词的意思是“感情”,这里需要一个名词,所以affect应该排除;defect“过失”;infection“感染”。
