Step 2 Presentation and practice

　　1. Subject clauses (ppt6-14)

1) Present the students several subject clauses.

　　 (1) That he will succeed is certain.

　　(2) Whether he will go there is not known.

　　(3) What he said is not true.

　　(4) Where he hid the money is to be found out.

　　(5) Whoever comes is welcome.

　　(6) How we can help the twins will be discussed at the meeting.

　　(7) When they'll start the project has not been decided yet.

Tell the students: Subject clauses can be introduced by that, whether or questions words.

2) What or that?

　　Give students two pairs of sentences introduced with what and that and ask the students to conclude their differences: when introducing the subject clause; that carries no meaning. What is usually used as the subject or object in the clause.

3) The use of "it".

Present students the following sentences:

　　(1) It is certain that he will succeed.

　　(2) It is not known whether he will go there.

　　(3) It has not been decided yet when they'll start the project

Tip: We often use it as a preparatory subject and the subject clause is put at the end of the sentence. In this case, the sentence is better balanced.

　　 1) Present some sentences and get the students to recognize the object clauses in them.

　　 (1) I heard (that) he joined the army.

　　 (2) She did not know what had happened.

　　 (3) I wonder whether you can change this note for me.

　　 (4) She told me that she would accept my invitation.

　　 (5) Our success depends upon how well we can cooperate with one another.

　　 (6) I am afraid (that) I've made a mistake.

2) Get the students to conclude three tips while using the object clauses by giving the example first.

Tip1: If there is more than one object clause, only the first that can be omitted.

Tip2: Preparatory it is used when there is an object complement.

Tip3: that is usually not used to introduce an object clause after a preposition except in that or except that.
