unit10:first conditional

unit 10:sentences 


First Conditional: real possibility

We are talking about the future. We are thinking about a particular condition or situation in the future, and the result of this condition. There is a real possibility that this condition will happen. For example, it is morning. You are at home. You plan to play tennis this afternoon. But there are some clouds in the sky. Imagine that it rains. What will you do?
IFconditionresult
present simpleWILL + base verb
Ifit rainsI will stay at home.
Notice that we are thinking about a future condition. It is not raining yet. But the sky is cloudy and you think that it could rain. We use the present simple tense to talk about the possible future condition. We use WILL + base verb to talk about the possible future result. The important thing about the first conditional is that there is a real possibility that the condition will happen. Here are some more examples (do you remember the two basic structures: [IF condition result] and [result IF condition]?):
IFconditionresult
present simpleWILL + base verb
IfI see MaryI will tell her.
IfTara is free tomorrowhe will invite her.
Ifthey do not pass their examtheir teacher will be sad.
Ifit rains tomorrowwill you stay at home?

 second conditional 
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.
