教学过程
教学过程 Step 1: Leading in 1. Let students watch a video about people and nature. Ask students to answer the following questions according to the video: (1)What do people do with the forests and animals in the video (2)What will happen if people continue to harm the nature (3)What can we do to protect the nature (Attention: Ask students to discuss the above three questions in groups and then share their answers to the whole class. Answers will vary.) 2. Ask students to work in groups of four and let students discuss the pollution they know. 3. Ask each group to summarize their discussion using thinking map (e.g. webbing chart). 4. Show the pictures of different kinds of pollution to students and let them learn some new phrases about pollution. 5. Ask students to think about the following two questions individually and then encourage some of them to share their opinions. (1)Do you know what caused the pollution (2)What should we do to save the earth Step 2: Presentation Ask students to read the words in the box first and then classify them by different types of pollution. Noise pollution — loud music, planes, building houses, mobile phones, machines, crowds, vehicles Air pollution — cars, factories, smoking, building houses, power plants, nuclear waste disposal Water pollution — rubbish, littering, ships, factories, industrial waste, pesticides Step 3: Listening 1. Let students work in pairs first to predict the answers to the activity, before the recording is played. Students can write the predicted answers on a separate piece of paper. Elicit some answers from students and write them on the board. 2. Play the recording for students to fill in the gaps and review the answers as a class. (Answers: really dirty, rubbish, fish, litter, waste, government, close down, clean up) 3. Ask students to listen again, and answer the questions: (1)What does Tony want to do later this afternoon (2)Why doesn’t Mark want to go with Tony (3)How was the river in the past 4. Show students the listening material, and let students read the listening material sentence by sentence following the recording. Step 4: Pair work Role-play the conversation in 1c. Mark: The river was dirty. Even the bottom of the river was full of rubbish. Tony: But it used to be so clean! Mark: Yes, but people are throwing litter into the river. Tony: Everyone in this town should play a part in cleaning it up! Step 5: Listening 1. Ask students to listen to the interview and circle the pollution that have been talked about. (Answers: circled: A, B) 2. Ask students to listen again and complete the sentences in 2b. Note: rubbish (British English)—things that people throw away trash / garbage (American English)—things that people throw away waste—rubbish and unwanted materials left behind after we have used something litter—things that people have thrown away and left on the ground in public places refuse—a more formal word for “rubbish” (Answers: 1. more cars 2. pollute 3. are throwing away 4. public places) 3. Show students the listening material, and ask students to read the conversation sentence by sentence following the recording. Step 6: Role-play 1. Ask students to role-play the conversation using the information in 2a and 2d. 2. Ask students to identify the ways of solving the environmental problems mentioned in the conversations without referring to their textbooks. 3. Ask students to write a short paragraph to summarize the problems and the suggested solutions. Step 7: Language points 1. try to do try to do可以理解为try one’s best to do，表示“努力去做某事”。 Every student should try to study hard in order to study in a university. 为了进入大学学习，每个学生都应该努力学习。 2. be related to be related to 意为“与……有关”。 I am not related to him in any way. 我和他无任何关系。 3. play a part in (1)play a part in 意为“在……方面起作用”，后面跟sth.或doing sth.。 A good diet plays a large part in helping people live longer. 健康的饮食在帮助人们长寿方面起着非常大的作用。 (2)play a part 还可意为“在……中扮演角色”。 He was invited to play a part in this TV play. 他被邀请参加这个电视剧的演出。 4. advantage advantage作名词，其反义词为disadvantage“缺点；不利条件”。take advantage of... 意为“利用……”。 It has both advantages and disadvantages. 它既有优点，有优缺点。 5. cost, spend, take与pay (1)cost的主语是物，宾语是金钱，sth. cost(s) (sb.) some money指“某物花费(某人)多少钱”； (2)spend的主语是人，宾语是时间或金钱，sb. spend(s) some time/ money on sth.指“某人花费时间/金钱在某事/物上”，sb. spend(s) some time/ money doing sth.指“某人花费时间/金钱做某事”； (3)take常用it作形式主语，宾语是时间，it takes sb. some time to do sth.指“做某事花费某人多长时间”； (4)pay主语是人，宾语是金钱，sb. pay(s) some money for sth.指“某人为某物付费”。
