Question: Should a scientist be responsible for the results of his or her work? Why or why not?(Suggested Answer: A scientist should always be responsible for the results of his or her work. He is a scientist and it is sometimes impossible for him to predict the moral consequences of his choice of a problem, however much he may wish to do so. But at the same time he is also a citizen, and citizens who have any special skill have an obligation to see, as far as they can, that their skill is utilized in accordance with the public interest. That is to say, a scientist has to consider moral factors before undertaking a new problem. This is particularly true in applied research, whose effects are more easily predictable. In any case, a scientist has a responsibility to make sure that the products of his discoveries work for, not against, the benefit of society. )（热身问题既与主题有关，便于因势利导，是一种“导入式”活动，易激发学生思考、参与，进行听说练习，学生自愿回答。）Introductory remarks:We all know that science plays a more and more important role in the societies in which we live, but it may not be so clear as to responsibilities scientists have to society. In fact even scientists conducting the most fundamental research need to be aware that their work can ultimately have a great impact on society. It is true that the occurrences and consequences of discoveries in basic research are sometimes virtually impossible top foresee. Nevertheless, the scientific community must recognize the potential for such discoveries and be prepared to address the questions that they raise. If scientists do find that their discoveries have implications for some important aspects of public affairs, they have a responsibility to call attention to the public issues involved. The important point is, therefore, that science and technology have become such essential parts of society that scientists can no longer isolate4 themselves from public concerns. Because of sciences function in modern society, scientists are increasingly called upon to contribute to public policy and to the public understanding of science. They play an important role in educating nonscientists about the content and processes of science. Text and Questions for Discussion2） 用相关图式进行解码：（对课文内容进行学习）Title: Social Responsibility of Scientists(Questions Related to the title:) What information can you get from the title? What is the scientists dilemma? Who should be responsible for the side-effects of an invention? Imagine what the author wants to tell us in the passage?（各组讨论并做出回答，然后选出2-3小组的代表，简明扼要的向全班作汇报）。( Whatever answers the students offer, the key meaning should be : )1) From the title, we know that the author wants to tell us social responsibility of scientists, scientists attitude toward their social responsibility and the authors view on the problem as well.2) The dilemma of the scientists is that what they originally thought to be beneficial to mankind may finally turn out to be something with adverse effects.3) According to Ernst Chain, it is up to society to take and pay for measures against the unwanted side-effects. (T: Now you have some idea of scientists work and scientists attitude toward their social responsibility. Lets move on to the text in very detail. So look at the first 3 paragraphs, and discuss the following questions)(学生快速浏览课文第一段，完成由教师结合pre-reading和while-reading设计的阅读任务，请学生分组讨论。使学生对课文第一段表达的意义和在全文中所起的作用有所理解。)Paragraph 1 &2: The writer raised the question: How far scientists should be responsible to society for the results of their work and in paragraph 2, the writer gives an example to explain it.According to the writer, scientists can fall into two categories: University scientists: They are free to choose their fields of research, so this question applies to them.Government scientists: They worked for bodies sponsored by government. They are not free to choose their research field and can not freely resigned from their post. This question does not apply to them.Questions:（教师根据课文内容设计问题，有助于学生快速解码。）1. What is the main idea of the paragraph?(the author raises the question: How far scientists should be responsible to society for the results of their work? )2. Why does the question apply to particularly to university scientist?(They are free to choose their field of research.)3. Why are the scientists who work for the government or for industry not responsible for the social responsibility?(They are not entirely free agents, short of resigning from their post.)4. Whats your opinion on the legal charge?(We have an opinion-The universitys defense: The results of research have been of benefit to the community as a whole. Through increased productivity and lower food prices, and in any case, the social consequences of its research were the responsibility of the whole community rather than the university. (由于对题目进行了讨论，对课文内容便有了大致的预见。用归纳和演绎相结合的启发式，使学生阅读课文第一段，从文章的第一段第一句“There has been much debate for a number of years about how far scientists should be responsible to society for the results of their work. ”知道了作者要讨论科学家的社会责任问题。让学生找出文章提出的观点，然后教师进行归纳，以便使学生对要点加深印象。 Paragraph 3:Scientists should not be responsible for the harmful effect their research may bring about.More details:A. Most scientists feel involved and have well-developed conscience for their result of their work.B. The problems are extremely complex.C. They often find them in a cruel dilemma.Questions:1. Whats the dilemma of the scientists?The dilemma is that what they originally thought to be beneficial to mankind may finally turn out to be something with adverse effects.Paragraph 4: What social responsibility (ties ) a scientist and a university should take.More details:A. Their duty is to keep the public informed and especially to advise politicians and other influential persons.B. The university should provide unbiased experts.C. Scientists should make the technological assessment foreseeable benefit and harmful effects, and these should be clearly stated for all to see.D. Conclusion: The decisions and responsibility should be shared by all sections of the community. (It is another opinion of this problem)Question:Whats the implication of the last sentence?(Public opinions about social values and goals may sometimes even more important than the problem itself.)Paragraph 5: Chains statement about the scientists social responsibility.Through two verbs we can clearly know this: one is “conclude”, the other is “says”.a) Chain concludes that scientists can not be held responsible for the unpleasant effects of their inventions; responsibility lies with the society that adopts the technological application.b) Chain says that one thing scientists can and should do is to counteract the tendency of the news media to exaggerate and sensationalize new developments.Question:Whats Chains opinion ?(It is up to takeand pay for measures against the wanted side-effects.)Paragraph 6: The authors view on the problem:A. A scientist should be responsible for presenting a true picture to the public about new developments in his own field, and for indicating possible implications so far as he can see. ( Scientists working in defence services, most of those in industry are not include.)B. Scientists must take a positive part, individually and collectively, in helping people understand the spirit of the brave new world. Question:Whats the writers view on this problem?(A final word: Whatever critics may say or wish, today science is an extremely important part of our culture, and modern civilization is in fact based on technology; there is no going back, and science and technology will influence our lives and the world we live in to an increasing extent.)（教师可以讲解文章或短文常规形式：起始段/主题段、主体段/发展段和结论段/总结。起始段里应引出话题或提出观点，主体段或发展段是对话题或主题的支撑，结论段给出判断或结论。把学生置于“作者”的位置，采用启发式和连环式问题，使学生不自觉地卷入学习课文活动之中。）Social Responsibility of Scientists Para1 Para 2 Para 3 Focus of the debate:How far scientists should be responsible to the society for the result of their work.Example to supportuniversity scientists should be responsible for theresult of workScientists feel involved and find them in a cruel dilemma. para 6 Para 5 para 4Chains statement about scientists responsibilityThe decisions and responsibility should be shared by all sections of the communityThe authors view on the problem 3) 语篇结构分析A: 文章体裁类型复习 ( Genre Analysis)T: After we study the text, with the help of discourse picture , we are clear about the organization of the text.

Students will tell that the passage in the text is Argumentation without difficulty.)B: 段落之间的关系T: We have classified the parts of the text and recognized the main idea of each part, it is necessary to explore how the author connects the three parts together logically and makes meanings of each part get together naturally and smoothly?(Ss are arranged to work in groups and are encouraged to find out the signal words connecting each parts.

The majority of scientists today work for the organizations that are financially supported by government and so the authorities that employ them have the responsibility and apart from giving up their posts, they are not free to do what
