Step II Revision and Lead-in

T: Yesterday, we learnt the use of Inversion and did some exercises. Can you

tell me the difference between inverted sentences and usual sentences? Wu

Li, would you like to have a try?

Sl: Yes. In an inverted sentence, part of the predicate or the whole predicate

comes before the subject. In a usual sentence, the predicate comes after the

subject.

T: Quite right. Sit down, please. Then for what reasons do you think Inversion is

used? Any volunteer?

Step IV Writing

T: As we all know, environment problems are becoming more and more serious with the development of modern agriculture and industry. Among all the problems, which do you think is the most serious one? Why do you think so? What do you think should be done to solve it? Now write a paragraph to tell your reader about these questions.

(Teacher writes the questions on the Bb. )

T: You can prepare your paragraph as follows: First, write a sentence that states

your opinion, for example,“I think that air pollution is the most serious problem because it does great harm to our health. ”Then list as many reasons as possible. Finally, use the sentences to organise your paragraph. Are you clear?

Ss: Yes.

T: Well. I'll show you some words and phrases on the screen. You can refer to

them. After finishing your paragraph, use the check list in Unit 2 to check it

for errors and mistakes. Are you clear?

Ss: Yes.

(Teacher shows the following on the screen and the students begin to work.)

Many products are bad for the environment.

It is wrong to buy products that are harmful to the environment.

To think that there is nothing we can do is incorrect.

What we do is important because it affects the environment I suggest that we do something about these problems.
