T:Look at the blackboard now.In all these structures,“it”is used as preparatory subjects.Can you tell me the real subjects in them?

Ss:Yes.Infinitives,-ing forms and clauses.

T:Quite right.You should remember and often use these structures.Besides,“it” can be used in some other structures to express “time”.Let’s do another exercise on the screen.

Complete the sentences

1.______(已經有三年了)since his father passed away.

2.______(不久)the police arrived.

T:Well,we also know that “it”can be used as an preparatory object.Let’s do an exercise.Look at the screen.

Rewrite the following sentences,using“it”as a preparatory object.

1.To make others laugh is difficult.(I found…)

2.To help him is my duty.(I consider…)

3.That we should keep calm is important.(I think…)

4.That he objected to the proposal is clear.(I made…)

T:Now I want some of you to rewrite the sentences one by one.Li Hao,the first one.

S1:I found it difficult to make others laugh.

T:The second one,Wang Hua.

S2:I consider it my duty to help him.

T:…

S3:I think it important that we should keep calm.

S4:I made it clear that he objected to the proposal.

T:Well done.From these sentences,we know that the commonest structure with “it” as a preparatory object is “subject+vt.+it+adj./n.+to do sth./that-clause.Some verbs like “find,feel,think，consider,make”are often used in this structure.Are you clear about it?

Ss:Yes.

(Bb:subject+vt.+it+adj./n.+to do sth./that-clause)

T:Well,besides the use as a preparatory subject or object,we all know “it” can be used to give special emphasis to almost any part of a sentence except the verb.Can you tell me the emphatic structure?

Ss:Yes.It is “It be+the emphasized part+who/that…”.

(Teacher writes the structure on the blackboard.)

T:Quite right.Now let’s look at the screen and do another exercise.(Teacher shows the following on the screen.)

Correct mistakes if there are any.

1.It is he that I want to see.

2.It is I who is leaving for London next week.

3.It was on Tuesday when Mrs Smith came.

T:Who’d like to do the first one?Any volunteer?

S1:Let me try,“him” should be used instead of “he”,because the emphasized part is an object.

T:Quite right.The second one?

S2:“is” after “who” should be replaced by “am” to agree with “I” in person and number.

T:…

S3:“when” should be replaced by “that” to give special emphasis to the adverbial of time.

T:You are all right.You’ve mastered this sentence structure very well.Now I will show you some other sentences.(Teacher shows them on the screen.)

1.It is my turn.

2.Let’s call it a day.

3.If the teacher sees you doing that,you will catch it.

4.Go ahead,we’ll make it in the end.

5.-I will study hard in the future.

-That’s it.

S1:輪到我了。

S2:今天就到這里吧。

S3：如果老師看到你這么做，你就會挨批評。

S4：繼續干吧，我們最終會成功的。

S5:-今后我會努力學習的。

-這就對了。

S6：別著急。

T：Very good.We can see in these sentences,“it” has no special meaning.Is that clear?

Ss:Yes.

T:Well,now let’s do more exercises to further master the use of “it”.
