Top Tips Grammar: Conditional using ‘if’

Main points

*You use conditional clauses to talk about a possible situation and its results.
*Conditional clauses can begin with ‘if’.
*A conditional clause needs a main clause to make a complete sentence.
*The conditional clause can come before or after the main clause.

 

a) You use conditional clauses to talk about a situation that might possibly happen and to say what its results might be.

You use ‘if’ to mention events and situations that happen often, that may happen in the future, that could have happened in the past but did not happen, or that are unlikely to happen at all.

- If the light comes on, the battery is OK.
- I’ll call you if I need you.
- If I had known, I’d have told you.
- If she asked me, I’d help her.

 

b) When you are talking about something that is generally true or happens often, you use a present or present perfect tense in the main clause and the conditional clause.

- If they lose weight during an illness, they soon regain it afterwards.
- If an advertisement does not tell the truth, the advertiser is committing an offence.
- If the baby is crying, it is probably hungry.
- If they have lost any money, they report it to me.

Remember that you don’t use the present continuous in both clauses. you don’t say ‘If they are losing money, they are getting angry’.

 

c) When you use a conditional clause with a present or present perfect tense, you often use an imperative in the main clause.

- Wake me up if you’re worried.
- If he has finished, ask him to leave quietly.
- If you are very early, don’t expect them to be ready.

 

d) When you are talking about something which my possibly happen in the future, you use  present or present perfect tense in the conditional clause, and the simple future in the main clause.

- If I marry Celia, we will need the money.
- If you are going to America, you will need a visa.
- If he has done the windows, he will want his money.

Remember that you don’t normally use ‘will’ in conditional clauses. You don’t say ‘If I will see you tomorrow, I will give you the book’.

 

e) When you are talking about something that you think is unlikely to happen, you use the past simple or past continuous in the conditional clause and ‘would’ in the main clause.

- If I had enough money, I would buy the car.
- If he was coming, he would ring.

Remember that you don’t normally use ‘would’ in conditional clauses. You don’t say ‘If I would do it, I would do it like this’.

 

f) ‘Where’ is sometimes used instead of ‘was’ in the conditional clause, especially after ‘I’.

- If I were as big as you, I would kill you.
- If I weren’t so busy, I would do it for you.

You often say ‘If I were you’ when you are giving someone advice.

- If I were you, I would take the money.
- I should keep out of Bernadette’s way if I were you.

 

g) When you are talking about something which could have happened in the past but which did not actually happen, you use the past perfect in the conditional clause. In the main clause, you use ‘would have’ and a past participle.

- If he had realized that, he would have run away.
- I wouldn’t have been depressed if I had known how common this feeling is.

Remember that you don’t use ‘would have’ in the conditional clause. Yu don’t say ‘If I would have seen him, I would have told him’.

Top Tips Grammar: ‘If’ with modals; ‘unless’

Main points

*You can use a modal in a conditional clause.
*You can use ‘unless’ to mention an exception to what you are saying.

 

a) You sometimes use modals in conditional clause. In the min clause, you can still use a present tense for events that happen often, ‘will’ for events that are quite likely in the future, ‘would’ for an event that is unlikely to happen, and ‘would have’ for events that were possible but did not happen.

-If he can’t come, he usually phones me.
- If they must have it today, they will have to come back at five o’clock.
- If I could only find the time, I’d go it gladly.
- If you could have seen him, you would have laughed too.

‘Should’ is sometimes used in conditional clauses to express greater uncertainty.

- If any visitors should come, I’ll say you aren’t here.

 

b) You can use other modals besides ‘will’, ‘would’ and ‘would have’ in the main clause with their usual meanings.

- She might phone me, if she has time.
- You could come, if you wanted to.
- If he sees you leaving, he may cry.

Note that you can have modals in both clauses: the main clause and the conditional clause.

- If he can’t come, he will phone.

 

c) In formal English, if the first verb in a conditional clause is ‘had’, ‘should’ or ‘were’, you can put the verb at the beginning of the clause and omit ‘if’.

For example, instead of saying, ‘If he should come, I will tell him you re sick’, it is possible to say ‘Should he come, I will tell him you are sick’.

- Should ministers decide to hold an inquiry, we would welcome it.
- Were it all true, it would still not excuse their actions.
- Had I known, I would not have done it.

 

d) When you want to mention an exception to what you are saying, you use a conditional clause beginning with ‘unless’.

- You will fail your exams.
- You will fail your exams unless you work harder.

Note that you can often use ‘if…not’ instead of ‘unless’.

- You will fail your exams if you do not work harder.

When you use ‘unless’, you use the same tenses that you use with ‘if’.

- She spends Sundays in the garden unless the weather is awful.
- We usually walk, unless we’re going shopping.
- He will not let you go unless he is forced to do so.
- You wouldn’t believe it, unless you saw it.

 

e) ‘If’ and ‘unless’ are not the only ways of beginning conditional clauses. You can also use ‘as long as’, ‘only if’, ‘provided’, ‘provided that’, ‘providing’, ‘providing that’, or ‘so long as’. These expressions are all used to indicate that one thing only happens or is true if another thing happens or is true.

- We were all right as long as we kept our heads down.
- I will come only if nothing is said to the press.
- She was prepared to come, provided that she could bring her daughter.
- Providing they remained at a safe distance, we would be all right.
- Detergent cannot harm a fabric, so long as it has been properly dissolved.

Top Tips Grammar: I wish, if only, … as if …

Main points

*You use ‘I wish’ and ‘If only’ to talk about wishes and regrets.
*You use ‘…as if…’ and ‘…as though…’ to show that the information in a manner clause is not or might not be true.

 

a) You can express what you want t happen now by using ‘I wish’ or ‘If only’ followed by a past simple verb.

- I wish he wasn’t here.
- If only she had a car.

Note that in formal English, you sometimes use ‘were’ instead of ‘was’ in sentences like these.

- I often wish that I were really wealthy.

When you want to express regret bout past events, you use the past perfect.

- I wish I hadn’t married him.

When you want to say that you wish that someone was able to do something, you use ‘could’.

- If only they could come with use!

When you want to say that you wish that someone was willing to do something, you use ‘would’.

- If only they would realize how stupid they’ve been.

 

b) When you want to indicate that the information in a manner clause might not be true, or is definitely not true, you use ‘as if’ or ‘as though’.

- She reacted as if she didn’t know about the race.
- She acts as though she owns the place.

After ‘as if’ or ‘as though’, you often use a past tense even when you are talking about the present, to emphasize that the information in the manner clause is not true. In informal English, you use ‘were’ instead of ‘was’.

- Presidents can’t dispose of companies as if people didn’t exit.
- She treats him as though he was her own son.
- He looked at me as though I were mad.

 

c) You can also use ‘as if’ or ‘as though’ to say how someone or something feels, looks, or sounds.

- She felt as if she had a fever.
- He looked as if he hadn’t slept very much.
- Mary sounded as though she had just run all the way.

You can also use ‘it looks’ and ‘it sounds’ with ‘as if’ and ‘as though’.

- It looks to me as if he wrote down some notes.
- It sounds to me as though he’s just being awkward.

 

d) When the subject of the manner clause and the main clause are the same, you can often use a participle in the manner and omit the subject and the verb ‘be’.

- He ran off to the house as if escaping.
- He looks his head as though dazzled by his own vision.

You can also use ‘as if’ or ‘as though’ with a ‘to’- infinitive clause.

- As if to remind him, the church clock struck eleven.

 

e) In informal speech, people often use ‘like’ instead of ‘as if’ or ‘as’ to say how a person feels, looks or sounds. Some speakers of English think that this use of ‘like’ is incorrect.

- He felt like he’d won the pools.
- You look like you’ve seen a ghost.
- You talk just like my father does.

You can also use ‘like’ in prepositional phrases to say how someone does something.

- He was sleeping like a baby.
- I behave like an idiot, and I’m sorry.
