1. CONDITIONAL SENTENCES, TYPE 1 AND 2
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 (inthe clause with if) is fulfilled.
1.1. Conditional Sentence Type 1
→ It is possible and also very likely that the condition will be fulfilled.
Form: 
if + Simple Present, will-Future
Example: If I find her address, I’ll send her an invitation.
The main clause can also be at the beginning of the sentence. In this case, don't use a comma.
Example: I will send her an invitation if I find heraddress.
Note: Main clause and / or if clause might be negative. See Simple Present and will-Future on how to form negative sentences.
Example: If I don’t see him this afternoon, I will phone him in the evening.
Use
Conditional Sentences Type I refer to the future. An action in the future will only happen if a certain condition is fulfilled by that time. We don't know for sure whether thecondition actually will be fulfilled or not, but the conditions seems rather realistic – so we think it is likely to happen.
Example: If I find her address, I’ll send her an invitation.
I want to send an invitation to a friend. I just have to find her address. I am quite sure, however, that I will find it.
Example: If John has the money, he will buy a Ferrari.
I know John very well and I know thathe earns a lot of money and that he loves Ferraris. So I think it is very likely that sooner or later he will have the money to buy a Ferrari.
