Step 1 lead in (PPT 4-7)

Teacher reminds students of the letters that Agony Aunt Annie wrote to Sarah and Andrew.

Q: What can we learn from her letters about friendship?

Students express their ideas freely. Then teacher concludes in this way:

To talk to a friend openly and sincerely when something unpleasant happens is very important if we are to keep the friendship. (to do as subject and predicative of a sentence)

We should always remind ourselves to trust our friends whatever happens. (to do as object complement of a sentence)

Students are asked to pay attention to the parts in bold, and thus To-infinitive is introduced.

Step 2 Different functions of To-infinitive (PPT 8-15)

1. Ss are asked to study the two letters on Page 5 again, this time trying to find out more To-infinitives in the letters and tell their functions in the sentences.

(1) You have every right to feel betrayed … (as attribute)

(2) … she wanted to embarrass you in public, … (as object)

(3)It seems you need to apologize quickly to avoid losing a good friend! (as object and adverbial respectively)

(4) …, one of you has to be first to admit … (as object and attribute respectively)

2. With the guidance of T, Ss try to conclude all the functions of To-infinitive:

动词不定式由“to+动词原形”构成,其否定形式是“not to do”。动词不定式可以单独使用或用作动词不定式短语的一个部分。不定式在句中可作主语、宾语、状语、表语和定语等,但不能单独作谓语。

作主语

To read English every day is necessary. (不定式to read English every day 作主语)

动词不定式作主语时,为了句子平衡,通常用it作形式主语,而把不定式放在谓语之后。例如:

It is necessary to read English every day.

It is a good idea to go for a picnic today.

作宾语

I want to see a film.(不定式to see a film 作宾语)

不定式作宾语时,若还带有宾语补足语,往往把不定式放在补足语后,用it作形式宾语。例如:

He find it difficult to learn Chinese.

We think it important to master a foreign language.
