First and Second Conditional Gap Fill

This is a gap fill exercise to help students distinguish between first and second conditionals and to correctly conjugate the verbs according to the convention for each type of conditional. This exercise is part of a complete lesson on the second conditional in our upper-intermediate English course.

Fill the gaps with the correct form of the verb in brackets. All of these sentences are either first or second conditionals. Look carefully at the form of the verb in each sentence to help you decide if the sentence is first or second conditional so that you can correctly conjugate the missing verb. If you need to revise these forms, check out the lesson on first and second conditional phrases here.
