- We use the first conditional to express possibility in the present or in the future.
- The subordinate clause (If-clause) has a verb in the present simple. The main clause is always in the future.
- "If I don't study, I won't pass my exams"
- "If the weather is good, we'll go for a walk in the park."
- "I will buy that CD if I have enough money."

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.
