Unit 2 The Power of Words
Part I Preparation
1. A brief introduction to the theme
In our personal lives, other people’s words can change our mood or even our attitudes. Words are an essential link between friends, relatives, colleagues and acquaintances. Using kind and thoughtful words to maintain and to improve our relationships is one way to contribute to the well-being of others. The written word is even more powerful than the spoken word because it can be kept and treasured as a permanent reminder of a positive gesture on the part of someone we knew or still know.
2. Talking about the sentences that have affected you.
1) Work in groups to tell each other the sentence that can change a day or even your attitude toward life.
2) T guides Ss to review some useful proverbs and sayings.
It is never too late to learn.
Where there is a will, there is a way.
Well begun, half done.
Time is money, but money is not time.
A life without a friend is a life without a sun.
Time and tide wait for no man.
3. Talking about dialects and Mandarin
Question: Is a dialect ever more useful than Mandarin? Why or why not?
4. Do Exercise 2: work in pairs to make up a story according to the pictures.

Unit Two Communication problems T eaching Objectives 1. Let the students have some ideas of the common ways we usually use in our daily life to communicate. 2. Make the students find the efficient ways to communicate with each other. 3. Let the students come up with the ways to avoid misunderstandings. T eaching allotment six academic hours Focus points 1.key words and phrases assume, conflict, convey, emphasis, ignore, misinterpret, react, verge, feel like, for effect, on the verge of, pull out, take----lightly 2.difficult sentences 1) When Martians and V enusians first got together, they encountered many of the problems with relationships we have today. 2) So when communication problems emerged, they assumed it was just one of those expected misunderstandings and that with a little assistance they would surely understand each other. 3) To fully express their feelings, women would tend to exaggerate the facts a little bit for effect and use various superlatives, metaphors, and generalizations. 3.grammar focus prefix “mis---”的不同意义 Related Information It is well-known that learning a second language is never easy, and, generally speaking, the older one is when one attempts a new language, the more difficult it becomes. This is at least partly due to what is known as language interference, meaning that the linguistic patterns of our first language interfere with those of the second because no two languages have exactly the same sounds and grammatical structures. The English language has a very large vocabulary because it has incorporated words from many other languages over the centuries. This is nowhere more apparent than in its color words. For example, there are many words that express the color “purple”, describing its different shades and hues: mauve, violet, lilac, or lavender. An interesting linguistic gender difference among native speakers of English is the likelihood of women using these color terms to differentiate between shades of purple, whereas, men will be satisfied with the one word “purple”. This is true of other color words too.

Part 1 Listening 1 Ex1: C A D C B Ex2: 1) approaching 2) left 3) toilet 4) locked 5) Tickets please 6) pushed 7) stamped Scripts: Two Belgians and two Dutchmen traveled regularly to work on the same train. After a while the Dutchmen saw that the two Belgians only had one ticket between them and asked how they managed to achieve this. The Belgians explained that when they heard the conductor approaching from the other end of the carriage, the two of them left their seats, went into the toilet and locked the door. When the conductor knocked on the toilet door, saying, "Tickets, please!", they pushed one ticket under the door. It was then stamped and pushed back under the door again. The Dutchmen thought this was a very good idea and the following morning bought one ticket between them. When they got to their carriage there was only one Belgian. They told him what they had done and asked the Belgian if he had a ticket as he was traveling on his own. The Belgian said he did not have a ticket at all and when they asked how he proposed to manage to travel free of charge, he told them they would have to wait and see until the conductor arrived, but he had no doubt that he would manage it without difficulty. As soon as they heard the conductor coming, the two Dutchmen immediately went to the toilet and locked the door. A few moments later, the Belgian followed them down the corridor and knocked on the toilet door, saying, "Tickets, please!" One ticket appeared under the door. Questions: 1. Where did the story take place 2. What did the two Dutchmen want to know from the two Belgians 3. How did the Dutchmen feel about the Belgians' behavior 4. What did the Belgian do when asked if he had a ticket 5. Who finally managed to travel free of charge Listening 2 Ex1: 1 department store 2. attend college 3. difficult 4. physical education 5. terrified Ex2: FTTFT Scripts: My name is Atsuko Saeki. I work as a salesclerk in a big department store in Fuji, Japan. Six years ago when I was 21 years old, I went to California to attend college. Life in the United States was much more difficult than I had ever imagined. It wasn't like the descriptions I had read in my textbooks. People often seemed tense and so I felt very alone. One of my hardest classes was physical education. We often played volleyball. All the other students were good at it, but I clearly wasn't. One afternoon, the teacher asked me to hit the ball to my classmates. For most people, this would be easy but I was terrified that I would make a fool of myself. When one of the boys on my team saw how nervous I was, he walked up to me and whispered, "Come on, you can do that." You can't imagine how those words of encouragement made me feel. I was so happy that I almost cried. I managed to hit the ball and I think I thanked the young man, but I'm not sure. I have never forgotten his kind words of encouragement. He probably doesn't even remember what he said to me or how much his kindness meant to me. Whenever things aren't going well, I think of those simple words of encouragement: Come on, you can do that.

课内阅读参考译文及课后习题答案(Book 4) Unit 1 享受幽默—什么东西令人开怀？ 1 听了一个有趣的故事会发笑、很开心，古今中外都一样。这一现象或许同语言本身一样悠久。那么，到底是什么东西会使一个故事或笑话让人感到滑稽可笑的呢？ 2 我是第一次辨识出幽默便喜欢上它的人，因此我曾试图跟学生议论和探讨幽默。这些学生文化差异很大，有来自拉丁美洲的，也有来自中国的。我还认真地思考过一些滑稽有趣的故事。这么做完全是出于自己的喜好。 3 为什么听我讲完一个笑话后，班上有些学生会笑得前仰后合，而其他学生看上去就像刚听我读了天气预报一样呢？显然，有些人对幽默比别人更敏感。而且，我们也发现有的人很善于讲笑话，而有的人要想说一点有趣的事却要费好大的劲。我们都听人说过这样的话：“我喜欢笑话，但我讲不好，也总是记不住。”有些人比别人更有幽默感，就像有些人更具有音乐、数学之类的才能一样。一个真正风趣的人在任何场合都有笑话可讲，而且讲了一个笑话，就会从他记忆里引出一连串的笑话。一个缺乏幽默感的人不可能成为一群人中最受欢迎的人。一个真正有幽默感的人不仅受人喜爱，而且在任何聚会上也往往是人们注意的焦点。这么说是有道理的。 4 甚至有些动物也具有幽默感。我岳母从前经常来我们家，并能住上很长一段时间。通常她不喜欢狗，但却很喜欢布利茨恩—我们养过的一条拉布拉多母猎犬。而且，她们的这种喜欢是相互的。布利茨恩在很小的时候就常常戏弄外祖母，当外祖母坐在起居室里她最喜欢的那张舒适的椅子上时，布利茨恩就故意把她卧室里的一只拖鞋叼到起居室，并在外祖母刚好够不到的地方蹦来跳去，一直逗到外祖母忍不住站起来去拿那只拖鞋。外祖母从椅子上一起来，布利茨恩就迅速跳上那椅子，从它那闪亮的棕色眼睛里掠过一丝拉布拉多式的微笑，无疑是在说：“啊哈，你又上了我的当。” 5 典型的笑话或幽默故事由明显的三部分构成。第一部分是铺垫（即背景），接下来是主干部分（即故事情节），随后便是妙语（即一个出人意料或令人惊讶的结尾）。如果这个妙语含有一定的幽默成分，这个笑话便会很有趣。通常笑话都包含这三部分，而且每部分都必须交代清楚。如果讲故事或说笑话的人使用听众都熟悉的手势和语言，则有助于增强效果。 6 我们可以对幽默这种娱乐形式，进行分析，从而发现究竟是什么使一个有趣的故事或笑话令人发笑。举例来说，最常见的幽默有以下几种，包括了从最显而易见的幽默到比较微妙含蓄的幽默。 7 “滑稽剧”是最明显的幽默。它语言简单、直截了当，常常以取笑他人为乐。说笑打闹这种形式过去是、现在仍然是滑稽说笑演员和小丑的惯用技巧。它为不同年龄、不同文化背景的人们所喜爱。几乎本世纪的每个讲英语的滑稽说笑演员都曾以这样或那样的方式说过下面这则笑话。一位男士问另一位男士：“昨晚我看到的那位和你在一起的贵妇是谁？”那位男士回答道：“那可不是什么贵妇，那是我老婆。”这个笑话的幽默之处在于第二位男士说他的妻子不是一位贵妇，也就是说她不是一个高雅的女人。这个笑话并没有因为经常讲而变得不再那么好笑。由于这是一个经典笑话，观众都知道要说什么，而且因为大家对这个笑话很熟悉而更加珍爱它。 8 中国的相声是一种特殊的滑稽剧。相声中两名中国喜剧演员幽默地谈论诸如官僚主义者、家庭问题或其他一些有关个人的话题。相声随处都能听到，无论是在乡村的小舞台上，还是在北京最大的剧院里，抑或在广播、电视上。它显然是中国人家喻户晓的一种传统的幽默形式。 9 “俏皮话”不像滑稽剧那样浅显，它是因语言的误用或误解而引人发笑。我特别喜欢

Learning some English grammar 3．Methods of Teaching Using multi-media teaching equipment Group-Discussion Living performance 4．Time Arrangement: Unit 1 Leisure Activities Part I Preparation Useful Information There are some people in society who either has to or want to work all the time. Most people, however, seek ways to socialize, to relax or to have fun during their leisure hours. Obviously people's tastes vary depending on their income and their age. But in recent years, the home entertainment, industry has grown all over the world. Instead of going out to see a movie or taking a walk in a park, people of all ages prefer to turn on the television and stay at home. More and more families have tape recorders, CD players, VCRs and VCDs to add to the variety of leisure activities in the home. In some countries, young people spend hours sitting in front of their computers, surfing on the Internet or playing computer games. Despite the rise in home entertainment, there are still many people who enjoy spending some of their leisure time attending sports events or participating in competitive sports or other physical activities such as dancing and tai chi (shadow boxing). Exercise not only contributes to good health but also takes the mind away from worries and troubles. Concerts, plays and other performances constitute another source of entertainment outside

Unit 6 Risks Risks and You At some time or other, all of us have played the part of a hypochondriac, imagining that we have some terrible disease on the strength of very minor symptoms. Some people just have to hear about a new disease and they begin checking themselves to see if they may be suffering from it. But fear of disease is not our only fear, and neither is risk of disease the only risk we run. Modern life is full of all manner of threats-to our lives, our peace of mind, our families, and our future. And from these threats come questions that we must pose to ourselves: Is the food I buy safe? Are toys for my children likely to hurt them? Should my family avoid smoked meats? Am I likely to be robbed on vacations? Our uncertainties multiply indefinitely. Anxiety about the risks of life is a bit like hypochondria; in both, the fear or anxiety feeds on partial information. But one sharp difference exists between the two. The hypochondriac can usually turn to a physician to get a definitive clarification of the situation-either you have the suspected disease or you don't. It is much more difficult when anxiety about other forms of risk is concerned, because with many risks, the situation is not as simple. Risks are almost always a matter of probability rather than certainty. You may ask, "Should I wear a seat belt?" If you' re going to have a head-on collision, of course. But what if you get hit from the side and end up trapped inside the vehicle, unable to escape because of a damaged seat belt mechanism? So does this mean that you should spend the extra money for an air bag? Again, in head-on collisions, it may well save your life. But what if the bag accidentally inflates while you are driving down the highway, thus causing an accident that would never have occurred otherwise? All of this is another way of saying that nothing we do is completely safe. There are risks, often potentially serious ones, associated with every hobby we have, every job we take, every food we eat-in other words, with every action. But the fact that there are risks associated with everything we are going to do does not, or should not, reduce us to trembling neurotics. Some actions are riskier than others. The point is to inform ourselves about the relevant risks and then act accordingly. For example, larger cars are generally safer than small ones in collisions. But how much safer? The answer is that you are roughly twice as likely to die in a serious crash in a
