5. Translate the sentences into Chinese.
1. 对乔治来说，伦敦这座城市就像一个他熟悉得不能再熟悉的老太太，她年事已高，只有从适当的角度看，才能让他想起她昔日的美貌，可最近却让人厌倦了。
2. 尽管生性愤世嫉俗、悲观厌世，但他却特别喜爱阅读经典游记。这样，即便是舒舒服服地坐在温暖的扶手椅上，他也可以神游到天涯海角。(注意：the classic works of travel writing译成中文时应简洁，不必逐字翻译。From the deep warmth of his armchair 字面意思是“从扶手椅温暖的深处出发，在心里去旅游”，翻译时应灵活处理，可译为“坐在扶手椅上，让心灵去旅游。”)
3. 乔治突然意识到，作为一个陌生人，他永远也不可能体验到他想象中的融融暖意和缤纷色彩。也许，帕尼奥尔笔下的普罗旺斯才是真实的，就像世界上其他地方一样。（注意：同样的中文表达用英文有不同的说法：was suddenly struck by the realization that=suddenly realized。）
4. 可不幸的是，他们请的歌舞团不是一家而是两家，这两个歌舞团不仅仅是竞争对手，而且是死对头，谁也不服谁。（主语转换：这个句子有两种译法，可以是“被请来的歌舞团不是一家而是两家它们……”，或“他们请的歌舞团不是一家而是两家，这两家歌舞团……”）
5.大约有100多人挤在这个大橱柜里，每个人都觉得要是纠正错误、离开这个地方就未免太尴尬了，每个人都尽力压低声音不笑出声来。(注意：everyone too embarrassed to correct their mistake by leaving如果直译成“太尴尬以至于不能以离开的方式纠正错误”不太通顺。所以翻译时需要拆分句子译文才能通顺。可以译为“每个人都觉得要是纠正错误，离开这个地方就未免太尴尬了。”)

1. He couldn't contain his curiosity, so he resolved to set off immediately to see what Provence was really like.
2. As the deadline approaches, he is spending more time searching for clues, making sure that the conclusion is matched by the fact.
3. Their quarrels continued at approximately two-day intervals for more than half a year, and neither wanted to yield to the other.
4. No sooner had we gone to bed than the door of the hotel burst open and a group of soldiers rushed in.
5. Due to the unexpected heavy rain, the time they spent on the road was twice as long as they had intended to.

8. Look at the sentence from the passage and answer the question.
Why does the write ask this question? ( c )
Now look at the passage and find more examples of focusing questions.
1.Have they always been clear about where they’re going in their lives, and now
that they have arrived, are they happy and healthy?
2.But what if success is extremely unlikely?
3.Can being too persistent have a negative effect on your health?
4.So why do Bulldogs finally say, “Enough is enough”?
9. Work in pairs and discuss the questions.
1. Do you think Bulldogs and Quitters really exist? Do you know why?
·Researchers must have based their ideas on real people, but can people really be divided in this way? Surely most people would be between the two extremes of Bulldogs and Quitters, and it would depend on the context or circumstances
·The same person might be a Quitter for some goals, but a Bulldog for some others. There must be other categories besides Bulldogs and Quitters.
2. What characters are traditionally given to animals in China? How useful is it to use them to refer to humans?
The most obvious examples are the characters Chinese people usually believe the 12 symbolic animals have. Many people in China and in the West are interested in these ideas, but perhaps mainly for fun. I don’t think it is very useful because not many people seem to believe that the animal signs have a strong influence on their lives.
Rat: intelligent, imaginative Ox: hard-working, patient
Tiger: loyal, courageous Rabbit: prudent, honest
Dragon: dynamic, lucky Snake: organized, wise
Horse: enthusiastic, enterprising Goat: gentle, adaptable
Monkey: intelligent, clear-minded Rooster: honest, courageous
Dog: faithful, reliable Pig: honest, tolerant
3. Do you think the psychological research of Bulldogs and Quitters described in the passage is useful? Why/Why not?
·I think such research with only two categories (Bulldogs and Quitters) is limited, but their link with health seems interesting.
·This magazine-type of article is trying to make psychology popular, but it is not real
science because it is over-simplified. The original research might have had more categories and would certainly have more details about the research methods.
4. Which maxim do you agree with most: the original version, or the W.C.Fields’version?
The original version is “If you don’t succeed, try, try again.” The W.C.Fields’ version adds the joke about quitting. I agree with the original version because I don’t think you should ever give up.
5. More than 2,000 years ago, the Roman writer Juvenal wrote that the first aspiration in life should be a healthy mind in a healthy body. Do you agree?
The famous saying is “Mens sana in corpore sano.” This means that we should keep fit physically in order to have a clear mind (rather than vice versa). There are counter-example, like Prof. Stephen Hawking, the Cambridge physicist in a wheelchair, who has done much of his theoretical work in physics when he can only move one finger (he obviously has a sound mind despite physical disability).

Unit 2 Mixed feelings Active Reading 1 How empathy unfolds I. Warming-up exercises 1. Look at the following pictures and describe the emotion shown in each picture. 2. Discuss the question: Do you sometimes try to hide your emotions? Why or why not? 3. Skim the text, and find out the definition of empathy and sympathy in the passage. Empathy originates from a sort of physical imitation of the distress of another, which then evokes the same feelings in oneself. (Para. 3) Sympathy is felt for the general plight of another with no sharing of what that other person is feeling. 4. Now decide whether the feelings or actions described below are a result of Sympathy(S)or Empathy (E). sending a card to someone who is in hospital feeling happy because your friend has won a scholarship to a prestigious university trying to comfort someone who has had bad news reacting physically when you see that someone is in pain collecting money to help the victims of a natural disaster crying at the end of a film Summary: Sympathy= I can understand your pain. Empathy= I feel your pain. II. Text Organization Cf. ppt. III. Comprehending the text 1. What did Hope do when she saw another baby fall? Tears welled up in her own eyes and she crawled off to be comforted by her mother. 2. Why did Michael give his teddy bear to Paul? He did it to comfort Paul. 3.

They believe that humans begin to experience empathy virtually from the day they are born. 5. Which example shows that babies sometimes don’t realize they aren’t the ones who are suffering? The example of babies who imitate the distress of someone else. 6. When was the word empathy first used in English to describe such reactions? The word empathy was first used in English in the 1920s by E. B. Titchener. 7. Why was the word sympathy not appropriate? It is not appropriate because sympathy is felt for the general plight of another with no sharing of what that other person is feeling; empathy means actually sharing or imagining another person’s feelings. 8.

课时作业1答案 Over 40 years ago，a country music DJ convention (大会) was held every year in Nashville，Tennessee.Many country performers used to attend (参加) the convention to give their performances.Fans would go to Nashville hoping to see their favorite performers.In the end，so many fans began showing up in Nashville that a festival named Fan Fair was born. The first Fan Fair was held in April 1972，in Nashville for four days.Some of c ountry music’s biggest stars attended.There were about fifty thousand fans.The first Fan Fair was so successful that planning began almost immediately for 1973.The date was changed to June，when the weather would be better.Over one hundred thousand fans attended the second Fan Fair. Every year brought so many performers and fans to Fan Fair that，in 1982，it was moved to the Tennessee State Fairgrounds.Fan Fair stayed at the fairgrounds for another nineteen years. There was always the unexpected during the festival.In 1974，former Beatle Paul McCartney attended.In 1992，more than six hundred reporters from Europe，Asia，and South America went to cover the appearance of a popular star，Billy Ray Cyrus，who had introduced a new country line dance.In 1996，Garth Brooks，who made a surprise appearance，signed autographs (签名) for 23 hours.
