Present simple or present continuous 2

We use the continuous form (DYNAMIC VERBS) for actions and happenings that have started but not finished (they are singing / it is snowing etc.). 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 say ‘I know’, or ‘they like’. 

The following verbs (STATIVE VERBS) are not normally used in the present continuous: 

Like 

Love 

Hate

Want

Need

Prefer

Know

Realize 

Suppose

Mean 

Understand 

Believe 

Remember 

Belong 

Contain 

Consist
