‘Should‘ (do) is used to say what we think is a good thing to do or the right thing to do (to give opinion about something). We often use should when we ask for or give an opinion about something.

For example:

  • I don’t think you should work so hard.
  • The government should do something about the economy.
  • You’ve been coughing a lot. You shouldn’t smoke so much.

‘Should’ is also to say something is not right or not we expect.

For example:

  • Those children shouldn’t be playing. They should be at school.

For the past, we use ‘should have’ (done) to say that someone did the wrong thing:

For example:

  • She’s feeling sick. She shouldn’t have eaten so much chocolate.
  • Why were you at home yesterday? You should have been at school.
