Conditional Sentences are also known as Conditional Clauses or If Clauses. They are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled. There are three types of Conditional Sentences.
Conditional Sentence Type 1
→ It is possible and also very likely that the condition will be fulfilled.
Examples: 1) If I find her address, I’ll send her an invitation. 2) If I find her address, I will send her an invitation. 3) I will send her an invitation if I find her address. 4) If I don’t see him this afternoon, I will phone him in the evening.
