Real and Unreal Conditional Form Worksheets

Review and Exercises

By

Here is a quick review of the first and second conditional forms. Both first and second conditional are used to imagine situations in the present or future.

In general, the first conditional, or real conditional is used to express what will happen if a certain event takes place in the present or future. It is called the real conditional because it refers to situations which are truly possible.

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.

First / Real Conditional

If + Subject + Present Simple (positive or negative) + Objects, Subject + Future with Will (positive or negative) + Objects

Examples:

If he finishes the work on time, we will play a round of golf this afternoon.
If the meeting is successful, we will become partners with Smith and Co.

NOTES

'Unless' can be used in the first conditional to mean 'if not'.

Examples:

Unless he hurries up, we will be late.
Unless it rains, we won't get wet.

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

Examples:

They will be very happy if he passes the exam.
Jane will marry Tom if he asks her tonight.

Second / Unreal Conditional

The second, or unreal conditional is used to speculate about things that are impossible or improbable.

If + Subject + Past Simple (positive or negative) + Objects, Subject + Would + Verb (positive or negative) + Objects

Examples:

If he won the lottery, he would buy a new home.
If they were happy, they'd have more fun.

NOTES

'Were' is used for all subjects. Some universities such as Cambridge University also accept 'was' as being correct. Others expect 'were' for all subjects.

Examples:

If I were you, I'd buy a new car.
If she were American, she could remain in the country.

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

Examples:

They would be rich if he were to invent a new type of battery.
Angela would be proud if her son got straight As at school.
