Today's mini lesson is about how to use 'let's' and the imperative.
We use ‘let’s + infinitive’ (without ‘to’) to make suggestions. It means the same as ‘shall we + infinitive’ or 'I suggest ...'. (Let’s = let us.)
Let’s go to the cinema tonight.
Let’s have a coffee!
If we want to make a negative, we say ‘let’s + not + infinitive’.
Let’s not go home early.
Let’s not wake up at 5 am!
We use imperatives to tell people what to do. They can be used to give instructions, give strong orders or give friendly invitations. It means something like 'you should' or 'you shouldn't.
The positive imperative is the infinitive without ‘to’.
Come here!
Please slow down.
We make the negative with ‘don’t’ or ‘do not’ + infinitive’.

Don’t worry – everything will be fine.
Please don’t be late.
