Grammar - GEPT Class

Dear All,
There are all the structures that we talked last Tuesday. I make examples with one verb, "work". Hope it will make you understand more.

1. Simple Present Tense - Talking about things you do regularly; or things you used to do it from time to time or something will never change.

I work everyday. / He works everyday.

2. Present Continuous - Talking about something is in progressing or something you can see that is happening.

I am working now. / He is working at the moment.

3. Simple Past - Talking about something happen in a specific past time.

I worked yesterday. / He worked yesterday.

4. Past Continuous - Talking about something is progressing in the past, however, you can't see something "WAS HAPPENING", therefore, there are two ways that you can make it. 1 is to use a specific time to talk about it. 2 is to use another issue which can emphasize what was happening.

I was working at 7 pm yesterday evening.

He was working when the power went off.

5. Future Tense - Talking about something happen in the future. There are two helping verbs that you can use to talk about "future". One is "WILL", the other one is "Be Going To". Generally, we use these two to talk about "future", but actually, there are some small differences. We use "WILL" to talk about something you "are willing to do". And we use "Be Going To" to talk about something that you plan to do it. No matter when you are going to do it, as long as it is in your plan, we use "Be Going To".

I will work for you. / He will work for you.

I am going to work tomorrow.
He is going to work tomorrow.

6. Present Perfect - Present Perfect is present tense, it is talking about the condition of the issue from a time in the past until now. The time that happened is NOT IMPORTANT but which the condition until now matters.

I have seen "Transformers" many times.
He has seen "Transformers" for 5 times.

I saw it last Sunday.
He saw it last Sunday.

7. Present Perfect Continuous - The same with Present Perfect but it emphasize more on "PROGRESSING" part.

I have worked as a teacher for 10 years.
( Means that I have the experience being a teacher for 10 years, doesn't mean that I AM STILL A TEACHER.)

I have been working as a teacher for 10 years.
( Means that I AM STILL A TEACHER.)
