8、:When Richard Feynman was young,he thought the only use for science was to make good things for people.However,after he worked on the atomic bomb,he realized that science could also be used for evil.He wondered what the value of science really was and he decided on three values.The first value is th

12、to make the audience aware of the significance of the freedom of thought and the value of doubt.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

13、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?”work on 从事于从事于get/be involved in 被卷入被卷入.之中之中 take sth seriously 重视，认真对待重视，认真对待Put another way,what is the value of the science I had long devoted myself to-the

15、o 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

16、 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.familiar(adj)熟悉的熟悉的-familiarity(n)熟悉，通晓熟悉，通晓 sth be familiar to sb 某物为某人所熟悉某物为某人所熟悉sb be familiar with sth 某人对某物很熟悉某人对某物很熟悉 enable sb to do sth 使某人能够做某事使某人能够做某事all ki

18、 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 ha

20、ist 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 goin
