6、 was awarded the Presidential Medal of Freedom, the highest civilian award in the United States. Hawking was the Lucasian Professor of Mathematics at the University of Cambridge for 30 years, taking up the post in 1979 and retiring on 1 October 2009.

7、Theoretical Cosmology in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge. He is also a Fellow of Gonville and Caius College, Cambridge and a Distinguished Research Chair at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario. He is known

8、for his contributions to the fields of cosmology and quantum gravity, especially in the context of black holes.

9、hich stayed on the British Sunday Times best-sellers list for a record-breaking 237 weeks. 2. Frankenstein: is a novel about a failed artificial life experiment that produced a monster, written by Mary Shelley.

11、ter, Sir Patrick Moore, from its first airing on 24 April 1957, making it the longest-running programme with the same presenter in television history.4.

12、s achievement, Einstein is often regarded as the father of modern physics and one of the most prolific intellects in human history. He received the 1921 Nobel Prize in Physics for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect. The latter

13、 was pivotal in establishing quantum theory within physics.Structure and main ideaPart 1 Paras1-3 To make informed decision about change, the public needs a basic understanding of science.Part 2 Paras4-6 What can be done to endure the public about science.Part 3 Para 7 With an informed public, human

14、 civilization will survive.Main Idea: to ensure the survival of human civilization, measures must be taken to help the public understand science. III Language Points1.Nor can one prevent further advances in the future. Why is this sentence reversed? The word “nor” here appears at the beginning of th

15、e sentence to give force to the negation. Nor will I deny that.2. The only way to prevent further developments would be a global state that suppressed anything new, and human initiative and inventiveness are such that even this wouldnt succeed. What is the grammatical function of the first “that Her

16、e “that” brings about an attributive clause. What does the structure “such that” here mean? The structure is used to give an explanation for something. What can we infer from this sentence? No way can suppress anything new, as human initiative and inventiveness do exist.3. All it would do is slow do

17、wn the rate of change. Why is there no “to” between “is” and “slow”? When “do” appears in the subject of a sentence, the sign “to” of an infinitive which is used as the predicative can be omitted. The first thing he did was (to) look for a guide.4. At the moment, the public is in two minds about sci

18、ence. What does “in two minds about” mean? Unable to decide whether or not you want sth. or want to do sth. What can we learn from the sentence? The public finds itself holding two contradictory viewpoints about science. On the one hand, it expects the improvement in the standard of living that has

19、been brought by science; on the other hand, it also distrusts science because it does not understand it.5. It is also an important element behind support for the Green parties. What does “it” refer to? The publics distrust of science. What part of speech is “support” here? It is a noun. 6. But in sc

20、hools science is often presented in a dry and uninteresting manner. But in schools science is often taught in a dull and boring way. 7. Maybe I would have sold twice as many copies without it. 如果不用这个公式的话，也许我能多卖出一倍的书。8. But I have sufficient faith in the good sense of the public to believe that we mi

21、ght prove this wrong. What does “sense” here mean? Power of judging. What does this sentence imply? The author believes that the public will have a good understanding about science and can make informed judgments by itself.南阳理工学院教案（课时备课）授课题目：Unit 3 Understanding Science Text A: Public Attitude towar
