III GRAMMARPOINT: FIRST CONDITIONAL

The first conditional refers to the future. It is used when there is a possibility that the if - event might happen. It is formed:

 

If + present simple+ future. If you come at two, they’ll be ready. or future+ if + present simple. They’ll be ready if you come at two.

 

Sometimes going to is used in the first conditional to describe a future plan.

Note!

When if + should is used, the conditional is less likely to be fulfilled.

The main clause usually has the verb in the future with will / shall. However, ‘begoing to’, future, future continuous, future perfect, imperative, can / could, may / might, should / ought to, must can be also used.
