Should and shouldn´t

We use should and shouldn't to give advice or to talk about what we think is right or wrong.

You should means something like I think it is a good idea for you to do it.

You shouldn't means something like I think it is a bad idea for you to do it.


Should is used to express the opinion of a speaker and often follows I think or I don't think.

EXAMPLES:
You should study for that exam.
He shouldn´t go to the park this Saturday.



Here I leave you some links with activities to practise should and shouldn´t:
