Modal verbs can and should


Should and Shouldn't - Use
  • 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 look tired. I think you should take a few days off.

     Alice works very long hours. She should to talk to her boss.

     - I have an English test tomorrow.
     - I shouldn't worry if I were you. You have worked really hard.

     - I never have enough money.
     - I don't think you should go out so much.


Should - Quick Grammar Note
To give advice to someone you can also say:
  • I should do it if I were you.
  • I shouldn't be so rude, if I were you.

When you regret not doing something in the past, you can say:
  • I shouldn't have spoken to him like that.

I should have apologized earlier.


Can or Can't

We use the modal can to make general statements about what is possible:
