Example : Group BA P.E teacher in the USA invented basketball in the nineteenth century.The worker cut down the trees yesterday.I made this model plane.Mr. Wang punished him.The cat ate the fish....Step 3: Let the Ss observe the two groups of sentences and try to find the differences between them. Move to past passive voice.T: Observe the two groups of sentences in your group and find out the differences between them.T: Hi, class, have you found anything different T: Your group is wonderful today. Anything else T: Great! Can you guess what we call the sentences in Group B T: Yes. You made it.

5 FinishingTask 2(5mins) Individual workPair work Step 1: Let the Ss read the examples in 2 and find the differences between Example One and Example Two.T: Now, read the examples in 2 and find the differences between Example One and Example Two.T: What differences have you found T: Superb! What else T: Right! If you can see the material with your naked eyes, you should use “be made of”. If not, use “be made from”. For example, the lock is made of metal. You can see it clearly with your naked eyes. But, as for the paper, you can’t see wood directly with your naked eyes, so you say the paper is made from wood. Now, look at the pictures below the dialogs. See if you can see the material with your naked eyes .T: Let’s puter desk, be made of or be made from T: Chopsticks ...T: Well done! How do we decide whether to use a preposition or not The answer is: if the action is done by the object itself, there is no need to use a preposition, and if not , then a preposition is needed .Step 2: Let the Ss make up similar dialogs in pairs. T: Now, let’s do pair work. Make up similar dialogs. Go ahead!T: I’d like some pairs to act out your dialogs . Which pair T:... Read the examples in 2 and find the differences between Example One and Example Two.S1:“Be made of”is used in Example 1 and “be made from” is used in Example 2.S2: There is a preposition “on” after “write”, but there is no preposition after “lock”.Ss: Be made of. Ss: Be made of. ...Make up similar dialogs in pairs.S1: What’s the computer desk made of S2: It’s made of wood S1: What’s it used for S2: It’s used for putting computers on. 这个部分分成两步骤来完成较好。第一，帮助学生区分be made of和be made from的用法。第二，如何运用介词。理解这两点，有利于学生构建对话。学生不能解释清楚的老师要补充。老师在此过程中，顺便解释lock。为了简单明了，老师可以用汉语解释，因为涉及到不少术语，学生难以听懂。
