Past Unreal Conditional Form Worksheets

Review and Exercises

By

Here is a quick review of the third, or past unreal conditional form. In general, the third conditional is used to imagine past situations results that would have been different if something else had been changed.

Teachers can use this guide on how to teach conditionals, as well as this conditional forms lesson plan to introduce and practice the first and second conditional forms in class.

Third / Past Unreal Conditional

If + Subject + Past Perfect (positive or negative) + Objects, Subject + Conditional Perfect (would have done, positive or negative) + Objects

Examples:

If he had finished the work on time, we would have played a round of golf yesterday afternoon.
If the meeting had been successful, we would have become partners with Smith and Co.

The 'if' clause can also be placed at the end of the sentence. In this case, no comma is required.

Examples:

They would have been very happy if he had passed the exam.
Jane would have married Tom if he had asked her.

Third Unreal Conditional with 'Wish'

'Wish' can also be used with the past perfect to express a desired, unreal result in the past.

Subject + Wish + Subject + Past Perfect (positive or negative) + Objects

Examples:

I wish I had had more time to study when I was young.
She wishes he had been promoted to CEO.
