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 {{U}}(67) {{/U}} on our lives. It seems that with
genetic engineering, science has moved from {{U}}(68) {{/U}} the natural
world to redesigning it. Now we must ask ourselves {{U}}(69)
{{/U}} this influence will be for better or for worse. However, scientists
remain {{U}}(70) {{/U}} in their opinions. Some have {{U}}(71)
{{/U}} against the hazards of genetic engineering, {{U}}(72) {{/U}}
others have dismissed these perils as inconsequential. Lewis Wolpert, professor
of biology at University College London, says, "There are no ethical
{{U}}(73) {{/U}} because you are not doing any {{U}}(74) {{/U}}
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 {{U}}(75) {{/U}} , why shouldn't we do it?" They are both
extremely {{U}}(76) {{/U}} of excuses that genetic engineering is a bad
idea. {{U}}(77) {{/U}} , two other prominent scientists have
{{U}}(78) {{/U}} their displeasure about genetic engineering. They have
made no {{U}}(79) {{/U}} of the rather strong and true feelings
{{U}}(80) {{/U}} genetic engineering. George Wald, Nobel Prize winning
biologist wrote recombinant DNA technology {{U}}(81) {{/U}} our society
with unprecedented problems in the history of science. It places in human hands
the {{U}}(82) {{/U}} to redesign living organisms, the {{U}}(83)
{{/U}} of some three billion years of evolution. It is happening too fast.
It {{U}}(84) {{/U}} probably the largest ethical problem, for going
{{U}}(85) {{/U}} in this direction may be not only unwise but
{{U}}(86) {{/U}} .
【正确答案】
C
【答案解析】名词辨义题【考频:39】。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……产生巨大的影响”,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”。
