| Step ⅠRevision Check the students’ homework and have a discussion with the students about the mistakes Mary made. Let the students have a clear understanding about the mistakes and then correct them. Step ⅡWarming up T: As we all know, we depend on energy to do many things in our daily life. Some people even say we could do nothing without energy. Can you tell me what we use energy for? Sa: Energy lights our cities. Sb: Energy heats our buildings. Sc: Energy entertains us. With the help of electricity, people have got a lot of fun from watching TV, playing computers and so on. Sd: There are many other electrical appliances that make our life more convenient and comfortable such as washing machines, microwaves, air conditioners and so on. Se: Today energy also helps people realize many so-called dreams in the past. For example, people can “fly” from one place to another by plane which runs on energy. Sf: It’s true. In fact, not only planes but also cars, ships and trains run on energy. T: Well done. All that you’ve just said is right. So it seems that energy plays a very important role in the modern world.

Many people have realized the problem. Next we’ll do some listening practice on this topic. Let’s see what other people think of this issue. The students are asked to read the questions quickly to find out the listening points first. Then listen to the tape twice and give the correct answers. T: Now please turn to page 31. Let’s do listening. Before you listen to the tape, please read fast the statements in Exercise 1 to find out the listening points. Pay much attention to the key points while listening. Play the tape for the first time. Help the students get a general understanding about the dialogue. The students listen and try to finish Exercise 1. Play the tape again, train the students’ ability to spot specific information and understand the implication in the dialogue. The students listen and finish T: Now read what Professor Chen and Li Bin say. Work in groups. Discuss who you agree with and give reasons. Use some of the phrases listed in Exercise 2 or any others you know. Step Ⅳ Homework 1. Review the new words and expressions you learned in this class. 2. Preview Reading. |
