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.
Form: if + Simple Present, will-Future
