(选自译林版必修第三册 Unit 4) The Value of Science When I was younger，I thought science would make good things for everybody.It was obviously useful；it was good.But then during the war I worked on the atomic bomb.This result of science was obviously very serious—it represented the destruction of people and it put our future at risk.I had to ask myself，“Is there some evil involved in science？” Put another way，what is the value of the science I had long devoted myself to—the thing I had loved—when I saw what terrible things it could do？It was a question I had to answer.I thought long and hard about this question，and I will try to answer it in this talk. The first way in which science is of value is familiar to everyone：scientific knowledge enables us to do and make all kinds of things.Of course，if we make good things，it is not only to the credit of science；it is also to the credit of the moral choice which led us to good work.Scientific knowledge is an enabling power to do either good or bad—but it does not carry instructions on how to apply it.Such power has obvious value—even though the power may be negated by what one does with it. Another value of science is the intellectual enjoyment it can provide us with.When we look at any question deeply enough，we feel the excitement and mystery coming to us again and again.With more knowledge comes a deeper，more wonderful mystery，inspiring one to look deeper still.Never concerned that the answer may let us down，with pleasure and confidence we turn over each new stone to find unimagined strangeness leading on to more wonderful questions and mysteries.Thanks to the scientific effort，we have been led to imagine all sorts of things more fantastic than poets and dreamers of the past ever could. I would now like to turn to a third value that science has.The scientist has a lot of experience with ignorance and doubt and uncertainty，and this experience is of very great importance.When a scientist doesn’t know the answer to a problem，he is ignorant.When he has an idea as to what the result is，he is uncertain.And when he is pretty sure of what the result is going to be，he is still in some doubt. Now，we scientists take it for granted that it is perfectly possible to live and not know.But our freedom to doubt was born out of a deep and strong struggle against authority in the early days of science.In order to progress，we must not forget the importance of this struggle；we must recognize our ignorance and leave room for doubt.Permit us to question—to doubt—to not be sure. It is our responsibility as scientists，knowing the great progress that is the fruit of freedom of thought，to declare the value of this freedom；to teach how doubt is not to be feared but to be welcomed and discussed；and to demand this freedom as our duty to all coming generations.

The experience with 8.ignorance，doubt and uncertainty is of great importance. Duty of scientists ·To declare progress is the fruit of 9.freedom of thought. ·To teach doubt is to be 10. welcomed and discussed. ·To demand this freedom as our duty to all coming generations. 1．work on 从事，致力于 2．put...at risk 使……处于危险中 3．to the credit of...归功于…… 4．negate vt.否认，否定；取消，使无效 5．intellectual adj.脑力的；有才智的，智力发达的 n．知识分子，脑力劳动者 6．let sb down 使某人失望　同义词：disappoint 7．ignorant adj.无知的，不了解的 8．take...for granted 认为……是理所当然；对……不予重视 9．declare vt.表明，宣称；公布，宣布；申报→declaration n．公告；宣告；宣言；声明 1．Put another way，what is the value of the science I had long devoted myself to—the thing I had loved—when I saw what terrible things it could do? [结构分析] 此句是复合句。I had long devoted myself to和I had loved都是省略了关系代词that/which的定语从句，分别修饰the science和the thing；when引导时间状语从句，what引导宾语从句。 [汉语翻译] 换言之，当我看到我长期投身其中、深爱着的科学竟能造成如此可怕的后果时，它的价值何在？ 2．The first way in which science is of value is familiar to everyone：scientific knowledge enables us to do and make all kinds of things. [结构分析] 此句是复合句，way作先行词后跟in which引导的定语从句，此时in which也可换成that。 [汉语翻译] 科学体现价值的第一种方式对每个人而言都耳熟能详：科学知识让我们能够做各种各样的事，制造不同种类的东西。 学科网（北京）股份有限公司 $
