TENSES

Present simple (  I do) and present continuous ( I am doing)

1. We use the present simple to describe things that are always true, or situations that exist now and, as far as we know, will go on indefinitely : It takes me ten minutes to get to STAN

2. To talk about particular actions or events that have begun but have not ended at the time of speaking, we use the present continuous : The bus isn't starting again.

3. We use the present simple to talk about habits or things that happen on a regular basis : I leave campus at 14.30 most days.

4. We use the present continuous to imply that a situation is or may be temporary

5. We often use the present simple with verbs that perform the action they describe
