Lesson 11 - Conditionals

CONDITIONALS The first conditional The second conditional The third conditional A conditional sentence is made up of two parts: an if-clause and a main clause. When the if-clause comes before the main clause, the two clauses are separated with a comma. When the main clause comes before the if-clause, then no comma is necessary. EXAMPLE: If Tom arrives early, we'll have dinner together. (If-clause comes before main clause. Comma required.) EXAMPLE: We'll have dinner together if Tom arrives early. (Main clause comes before the if-clause. No comma required.) There are three main types of conditional. They are commonly referred to as the first, second and third conditionals (or the Type 1, Type 2 or Type 3 conditionals.)
