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
