Present Continuous and Present Simple 2

We use continuous forms for actions and happening that have started but not finished. Some verbs (for example know and like) are not normally used in this way.
We don't say "I am knowing" or "they are liking"; we rather say I know, they like.

This is a list of verbs, that are normally used in the present continuous:
believe, fit, hate, like, love, need, prefer, know, realise, mean, remember, belong,  seem, suppose, understand, want

Present Continuous and Present Simple 1

Compare:
Present Continuous (I am doing)

we use the the continuous for things happening at or around the time of speaking; the action is not complete.


 Present Simple (I do)

we use the present simple for things in general or things that happen repeatedly

compare:
- The water is boiling. / - The water boils at 100 degrees Celsius.
- Let's go out, it isn't raining now. / - It doesn't rain very much in this region.

- I'm getting hungry.  / - I always get hungry in the evening

We use the continuous for temporary situations:
- I am living with my parents until i find a place of my own. /
- My parents live in Madrid; they have lived there all their lives.

Also:
- I always do (something) = I do it every time : 
I always go to University by car

- "I am always doing something" has a different meaning.
I' ve lost my keys again! I'm always losing things!
