If Clause Type 1

If-Clause Type 1

If-Clause Type 2

If-Clause Type 3

We use the first conditional, when we are referring to something that is possible or likely to happen,

because its possible to fulfil the action.

E.g. If we hurry, we will catch the bus.

If	Present Simple	Main clause: Will-Future or Modal Verb	Base Form + complement
If I	study,	I will	pass the exam.
If it	doesn't rain,	we will	be having a picnic.
If Henry	jogs regularly,	he might	lose weight
If Matthew	is to a job interview,	he should	wear a tie.

Note: The verb in the if-clause is almost always in the present simple.

e.g. If you call him, he will come.

But we can use the future tense will in the if-clause, when we are making a request.

e.g. If you will wait just a moment. I will find someone to help you.

We can also use the present continuous ( are doing) or the present perfect (have done) in the if clause.

e.g. If we're expecting visitors, the house will need a good clean.

e.g. If you have finished with the computer, I'll put it away.

We can use the first conditional in offers and suggestions.

e.g. If you need a ticket, I can get you one.

e.g. If you feel like travelling to Brazil, we can go there in August.

we can also use the first conditional, in warnings and threats.

e.g. If you go out with this clothes, you'll make yourself ill.

e.g. If you don't apologise, I'll never speak to you again.

We sometimes use the present simple in both clauses (if-clause and main clause).

e.g. If you heat water, it boils.

e.g. If you press this switch, the computer comes on.
