Should and shouldn’t for advice

A2  A2 grammar · lesson 16 of 25

Should is the most common way to give advice in English. You use it to say what is a good idea or a bad idea.

Form

should / shouldn’t + base verb. Like must and will, it is the same for every person: no -s, no to.

PositiveNegativeQuestion
You should rest.You shouldn’t (should not) work so much.Should I call the doctor?
She should study more.He shouldn’t eat so much sugar.What should we do?

Use: advice and opinions

Should = it is a good idea. Shouldn’t = it is a bad idea. It is softer than must: with should, the person can choose.

You look tired. You should go to bed early.

You shouldn’t drink coffee in the evening.

Tom should wear a coat. It’s cold outside.

Children shouldn’t watch TV all day.

We should leave now, or we’ll miss the bus.

‘I’ve got a headache.’ ‘You should take a break.’

Should I bring anything to the party?

Where should we go on holiday?

Making advice softer

We often start with I think or I don’t think. As with will, say I don’t think you should… rather than I think you shouldn’t….

I think you should talk to your teacher.

I don’t think you should buy that phone. It’s too expensive.

Tip: Must is strong: a rule or a strong feeling. Should is friendly: advice. You must stop at a red light (law). You should try this cake (my advice).
