The verb "have"

I want you to understand how the verb "have" is used in the present tense and the past tense before you learn about the present perfect tense in Monday's lesson on January 5 (Lesson 3, the Present Perfect).This is important because "have" is a main verb and it's a helping verb. Look at the examples below:

I have a new computer. ("Have" is the main verb in the present tense)

He has a big problem. ("Have" is the main verb in the present tense)

He doesn't have time . ("Have" is the main verb, negative, in the present tense)

We had fun yesterday. ("Have" is the main verb in the past tense)

They didn't have any bagels. ("Have" is the main verb, negative, in the past tense)

I have had Thai food. ("Have" is the main verb in the present perfect tense)

You haven't had Thai food. ("Have" is the main verb, negative in the present perfect tense)�
