Lesson aims

After this lesson you can:

• Explain the different conditional clauses;
• Name the different conditional clauses;
• Practice with the different conditional clauses.

Conditional clauses

There are four types of conditional clauses:

• Zero conditional (present simple + present simple)
• First conditional (present simple + will+infinitive)
• Second conditional (past simple + would+infinitive)
• Third conditional (past perfect + would have+past participle)

Zero conditional

• Used for statements that are always true
• If-clause is in present simple
• Main clause is in present simple
• Example: If you heat ice, it melts.
• Both clauses in present simple

First conditional

• Used for statements that are very likely to happen
• Main clause describes what will happen
• If-clause is in present simple
• Main clause is in will+infinitive
• Example: If you work hard, you will be rewarded.
• Present simple + will+infinitive  

Second conditional

• Used when something is unlikely to happen.
• Main clause describes what would happen in this unlikely situation
• If-clause is in past simple
• Main clause is would+infinitive
• Example: If I won the lottery, I would buy a car.
• Past simple + would+infinitive 

Third conditional

• Used when you think of a different past that would have resulted in a different outcome;
• You can switch the if-clause and the main clause around;
• If you switch them around, you do not use a comma;
• If-clause is in past perfect;
• Main clause is would have + past participle;
• Example: If she had known it was going to rain, she would never have gone to the beach.
• Second example (main clause first): She would never have gone to the beach if she had known it was going to rain. (NO COMMA!)

To summarize

• Zero conditional when: statements are true.
• Example: If you heat up water, it boils.
• First conditional when: something is likely to happen.
• Example: If I earn enough money, I will go on holiday.
• Second conditional when: something is unlikely to happen.
• Example: If I was famous, I would help everyone.
• Third conditional when: You think of a different past that would have changed the outcome.
• Example: If she had known it was going to rain, she would have worn a raincoat. 

If you don't use an umbrella when it rains, you get wet.
