conditional

The first conditional

We use the First Conditional to talk about future events that are likely to happen.

• If we take John, he'll be really pleased.
• If you give me some money, I'll pay you back tomorrow.
• If they tell us they want it, we'll have to give it to them.
• If Mary comes, she'll want to drive.

The 'if' clause can be used with different present forms.

• If I go to New York again, I'll buy you a souvenir from the Empire State Building.
• If he's feeling better, he'll come.
• If she hasn't heard the bad news yet, I'll tell her.

The "future clause" can contain 'going to' or the future perfect as well as 'will'.

• If I see him, I'm going to tell him exactly how angry I am.
• If we don't get the contract, we'll have wasted a lot of time and money.

The "future clause" can also contain other modal verbs such as 'can' and 'must'.

• If you go to New York, you must have the cheesecake in Lindy's.
• If he comes, you can get a lift home with him.

Second conditional

The Second Conditional is used to talk about 'impossible' situations.

• If we were in London today, we would be able to go to the concert in Hyde Park.
• If I had millions dollars, I'd give a lot to charity.
• If there were no hungry people in this world, it would be a much better place.
• If everyone had clean water to drink, there would be a lot less disease.

Note that after I / he/ she /it we often use the subjunctive form 'were' and not 'was'. (Some people think that 'were' is the only 'correct' form but other people think 'was' is equally 'correct' .)

• If she were happy in her job, she wouldn't be looking for another one.
• If I lived in Japan, I'd have sushi every day.
• If they were to enter our market, we'd have big problems.

Note the form 'If I were you' which is often used to give advice.

• If I were you, I'd look for a new place to live.
• If I were you, I'd go back to school and get more qualifications.

The Second Conditional is also used to talk about 'unlikely' situations.

• If I went to China, I'd visit the Great Wall.
• If I was the President, I'd reduce taxes.
• If you were in my position, you'd understand.

Note that the choice between the first and the second conditional is often a question of the speaker's attitude rather than of facts. Compare these examples. Otto thinks these things are possible, Peter doesn't.

• Otto – If I win the lottery, I'll buy a big house.
• Peter – If I won the lottery, I'd buy a big house.
• Otto – If I get promoted, I'll throw a big party.
• Peter – If I got promoted, I'd throw a big party.
• Otto – If my team win the Cup, I'll buy champagne for everybody.
• Peter – If my team won the Cup, I'd buy champagne for everybody.

Note that the 'If clause' can contain the past simple or the past continuous.

• If I was still working in Brighton, I would commute by train.
• If she were coming, she would be here by now.
• If they were thinking of selling, I would want to buy.

Note that the main clause can contain 'would' 'could' or 'might.

• If I had the chance to do it again, I would do it differently.
• If we met up for lunch, we could go to that new restaurant.
• If I spoke to him directly, I might be able to persuade him.

Also note that sometimes the 'if clause' is implied rather than spoken.

• What would I do without you? ("if you weren't here")
• Where would I get one at this time of night? ("if I wanted one")
• He wouldn't agree. ("if I asked him")
   
  Third conditional

  We can use the Third Conditional to talk about 'impossible' conditions, impossible because they are in the past and we cannot change what has happened.

  • If I had worked harder at school, I would have got better grades.
  • If I had had time, I would have gone to see him. But I didn't have time.
  • If we had bought that house, we would have had to rebuild the kitchen.
  • If we had caught the earlier train, we would have got there on time but we were late.

  Notice that the main clause can contain 'would', 'could' or 'might.

  • If I had seen him at the meeting, I would have asked him. (But he wasn't there so I didn't.)
  • If I had seen him at the meeting, I could have asked him. ( But he wasn't there so it wasn't possible.)
  • If I had seen him at the meeting, I might have asked him. (But I'm not sure. Perhaps if the opportunity had arisen.)
  • If I had paid more attention in class, I would have understood the lesson.

  Also notice that sometimes the 'if clause' is implied rather than spoken.

  • I'd have done it. ("if you had asked me but you didn't.")
  • I wouldn't have said that. ("if I'd been there.")
  • He wouldn't have let him get away with that. ("if he had tried that with me.")
