             All these sentences tell us that something is necessary or must happen before another
             thing can happen. Each sentence tells us that a certain situation must exist for a
             condition to be fulfilled.



                       A sentence that has two clauses—one that tells about a condition and the other
                       that tells about the result—is called a conditional sentence.
                       A conditional sentence is used to talk about a result that may happen only
                        if a condition happens first.



             A conditional sentence is made of two parts—an if clause and a main clause.
             For example,


                   Conditional (dependent) clause                           Main clause

                If it rains,                                  we will cancel the trip.

                If you do not hurry,                          you will miss the train.
