Study this example situation:

Alex is a bus driver, but now he is in bed asleep.
He is not driving a bus. (He is asleep.)
but He drives a bus. (He is a bus driver.)
Drive(s)/work(s)/do(es) etc. is the present simple:
I/we/you/they | drive/work/do etc. |
he/she/it | drives/works/does etc. |
We use the present simple to talk about things in general. We use it to say that something happens all the time or repeatedly, or that something is true in general:
- Nurses look after patients in hospitals.
- I usually go away at weekends.
- The earth goes round the sun.
- The cafe opens at 7.30 in the morning.
Remember:
I work ... but He works ...
They teach ... but My sister teaches ...
For spelling (
-s or
-es), see Appendix 6.
We use do/does to make questions and negative sentences:
do does | I/we/you/they he/she/ it | work? drive? do? |
I/we/you/they he/she/it | don't doesn't | work drive do |
- I come from Canada. Where do you come from?
- I don't go away very often.
- What does this word mean? (not What means this word?)
- Rice doesn't grow in cold climates.
In the following examples,
do is also the main verb (do you
do / doesn't
do etc.):
- 'What do you do?' 'I work in a shop.'
- He's always so lazy. He doesn't do anything to help.
We use the present simple to say how often we do things:
- I get up at 8 o'clock every morning.
- How often do you go to the dentist?
- julie doesn't drink tea very often.
- Robert usually goes away two or three times a year.
I promise / I apologise etc.
Sometimes we do things by saying something. For example, when you
promise to do something, you can say '
I promise ... '; when you
suggest something, you can say '
I suggest ... ':
- I promise I won't be late. (not I'm promising)
- 'What do you suggest I do?' 'I suggest that you ... '
In the same way we say: I apologise ... / I advise ... / I insist ... / I agree ... / I refuse ... etc.
