GRAMMAR 7 CONDITIONALS
Real/likely situations: first conditional
Unreal/imaginary situations: second conditional
Explanations
■ With if
A first conditional describes a real or likely situation. A present tense is used after if, but the time referred to is the future. WillAVon't are common in the result clause.
If you fall, I won't be able to catch you! This means that there is a real possibility this will happen. Going to can be used instead of will.
If it rains, we're going to get wet. The modal verb can is also common in first conditional sentences.
If the cases are too heavy, I can help you carry them.
i  Unless, provided, as long as Unless means If... not.
Unless you leave at once, I'll call the police. If you don't leave at once, I'll call the police. Provided and as long as can also introduce a condition. Provided you leave now, you'll catch the train.
With the imperative
It is common to use the imperative instead of if. Get me some cigarettes, and I'll pay you later.
With should
We can use shoidd instead of if in a conditional sentence. It means if by any chance ... and makes the action less likely.
Should you see John, can you give him a message?
With if
A second conditional describes an unreal or imaginary situation. A past simple tense is used after if, but the time referred to is the future. Woidd is common in the result clause.
If you fell, you would hurt yourself. This means that there is a small possibility that this will happen. The situation and its result are imagined.
The modal verbs might and could are common in second conditional sentences.
If you became a millionaire, you might be unhappy. Were
Were is often used instead of was in formal language. Note that were is not stressed in speech.
Unreal/imaginary past situations: third conditional
Other if sentences
If I were taller, I'd join the basketball team.
If I were you, I'd leave now. (I and you are stressed in speech)
■ Were to
Were to is another way of expressing a second conditional sentence. If they were to offer me the job, I'd turn it down.
■ With if
A third conditional describes an unreal or imaginary situation in the past. A past perfect tense is used after if. Would + have + past participle is used in the result clause.
If John had studied more, he would have got better marks. This means that John didn't study more. A past situation, different to the one that really happened, is imagined.
The modal verbs might and could are common in this kind of sentence. If you had tried harder, you might have succeeded.
■ Mixed conditions
For past events which have a result continuing in the present, it is possible to use the form of a third conditional in the i/-clause, and the form of a second conditional in the result clause.
If you had saved some money, you wouldn't be so hard up.
If can mean when in the sense of whenever.
If/When/Whenever it rains, we play football indoors instead. In this type of sentence we use the present simple in both the //"-clause and the result clause.
If can also mean if it is true that.
If (it is true that) you have a job like that, you are very lucky.
If (it is true that) nothing happened, you were lucky. If+ past simple can be used for past events with a real possibility, or that we know are true. This type of sentence does not have any special grammar ruies.
If you missed the TV programme last night, you can borrow my recording.
If the police arrested him, they must suspect him.

The present tense foTm in first conditional sentences does not refer to present time. It refers to future time.
The past tense form in second conditional sentences does not refer to past time. It refers to future time.
The difference between first and second conditional sentences can depend on the attitude of the speaker. The future situation might have a high possibility of happening (first conditional) or a low possibility (second conditional).
