Lesson Four

The Present Perfect Tense - Negative

S + have or has + not + past participle

Singular
Plural
I have not worked
We have not worked
You have not worked
You have not worked
He has not worked
She has not worked
They have not worked
It has not worked

Notice the use of "has" for a man, a woman, or a thing.

Also, it's important to know the irregular past participles.

 

Most Americans use the contracted form:

have + not = haven't   /   has + not = hasn't

Singular
Plural
I haven't worked
We haven't worked
You haven't worked
You haven't worked
He hasn't worked
She hasn't worked
They haven't worked
It hasn't worked
