First conditional

CONTIDIONAL SENTENCES are also known as Conditional Clauses or If Clauses. They are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled.

First conditional

As all conditionals, the first one has two parts: the condition and the consequence. We express the condition using:

First conditional

We can put either part first. If the condition or if part is first, we put a comma after it.

If you learn to manage your stress, you’ll feel much better

You’ll feel much better if you learn to manage your stress

First conditional

We use the first conditional to talk about events that are likely to happen and their consequences.

First conditional

Example:

How will you know if you never try it?

First conditional

With ‘if’, ‘when’, ‘unless’, ‘as soon as’, ‘until’

'When' and 'as soon as...'

As well as if, we can use other conjunctions. We use when and as soon as if we are sure the condition will be met. As soon as means ‘immediately after’.

First conditional

'When' and 'as soon as...'

Example:

When he calms down, he’ll be easier to talk to

First conditional

With ‘if’, ‘when’, ‘unless’, ‘as soon as’, ‘until’

‘Until’

We use until to refer to a point in time when something will change. We often use it to mean ‘before’.

First conditional

'When' and 'as soon as...'

Example:

Mum won’t serve dinner until you get home

(She won’t serve it before you get home)

First conditional

With ‘if’, ‘when’, ‘unless’, ‘as soon as’, ‘until’

‘Unless’

Unless means ‘except if’ or ‘if…not’

She won’t do it unless you tell her to

(She won’t do it except if you tell her)

First conditional

With modals

Normally WILL is used in the main clause of first conditional sentences. However you can also use the modal verbs MUST, MAY, MIGHT and COULD when something is a possible consequence (and not a certain one) in the future.

First conditional

With modals

Example:

Sarah might not come on Saturday if her aunt comes to stay

First conditional

Imperative conditionals

We also use an imperative in the will part.

First conditional

Imperative conditionals

If you’re ever back here again, don’t forget to come and see me
