Step 3 Discovering useful structures (Subject-verb agreement)

1.Brainstorm　Subject-verb agreement by giving simple examples.

T: Now watch me. What am I doing?(draws a picture on the blackboard)

Ss: You are drawing on the blackboard.

T: Yes. The teacher is drawing on the blackboard.(Writes the sentence "The teacher is drawing on the blackboard".) What about you? What are you doing?

Ss: We are watching and listening to you.

T: (Writes the sentence "We are watching and listening to you.")

The teacher is drawing on the blackboard.

We are watching and listening to you. Now please have a look at these two sentences. Can we say the teacher are drawing or we is watching and listening to the teacher?

Ss: No.

T: Why?

Ss: There are some rules for us to follow when we write sentences.

T: You are right. When we write a sentence the predicate should agree with the subject, which is called subject-verb agreement. If we can not apply the rules correctly, we might not get ourselves understood.
