1 Revision & lead-in(10mins) Class activity Group workGroup work Step 1: Let the Ss change the sentences in Group A into present passive voice.T: Look at these sentences and try to change them into passive voice. T: xxx, do you want to try the first one T: Wonderful! The second one Example: Group APeople speak English around the world.The monkeys eat the bananas.Water washes away the earth.The chemical factory pollutes the river....Step 2: Present the sentences in Group B and encourage the Ss to discuss in groups and change them into passive voice, too. T: You have done very well. Now look at this group of sentences. Again, you change them into passive voice, but this time, you will discuss in groups first.T：Any volunteers T: Which group has different opinions T: That’s nice. How about Sentence Two T: Perfect! 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.

Anything else T: Great! Can you guess what we call the sentences in Group B T: Yes. You made it. Could you tell me the structure of it Change the present active voice into passive voice.S1: English is spoken by people around the world.

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 “l(fā)ock”.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. 這個(gè)部分分成兩步驟來完成較好。第一，幫助學(xué)生區(qū)分be made of和be made from的用法。第二，如何運(yùn)用介詞。理解這兩點(diǎn)，有利于學(xué)生構(gòu)建對(duì)話。學(xué)生不能解釋清楚的老師要補(bǔ)充。老師在此過程中，順便解釋lock。為了簡(jiǎn)單明了，老師可以用漢語(yǔ)解釋，因?yàn)樯婕暗讲簧傩g(shù)語(yǔ)，學(xué)生難以聽懂。
