When do we use has, have and had?

[ahmin92]

I'm confused about when to use has,have, and had. I've googled a lot but non of them are helpful. Can anyone give me detail explanation? I only know has/have/had + past participle. That's all. I always mess up with present tense and present perfect tense. Someone help me please...

The verb "to have" present tense:
I have
He, she, it has
You have
We have
They have
Past tense:
I/he/you/we/they had.

"I have a computer."
"S/he has a computer."
"John had a computer, but he doesn't have it any more."
Does that help?

This is rather too broad a question to answer in one thread. Do you understand the difference between the meanings of these groups of sentences?

1. Present Simple:

a.I have a headache.
b. She has a headache.
c. I work in Prague.

2. Past Simple.

a. I had a headache yesterday.
b. She had a headache yesterday.
c. I worked in Oman from 2004 to 2005.

3. Present Pefect.

a. I have had a headache since seven o'clock/for three hours.
b. She has had a headache since she got up/for three hours.
c. I have worked in Prague since 20005/for seven years.


Try to identify what precisely puzzles you.

1. Present Simple:

2. Past Simple.

a. I had a headache yesterday.(My headache is gone, i had it yesterday)

b. She has had a headache since she got up/for three hours.
c. I have worked in Prague since 20005/for seven years.( I only get to understand this. The above, not sure.)

I know has have had don't mention time/date right? That's why you used I WORKED in Oman instead of I have worked in oman from 2004 to 2005?

Yes, both are correct, the second one is present perfect.
