									Conditional Sentences
“If grandma had wheels she‟d be a bicycle.”

Conditional sentences
•Conditional Sentences are also known as Conditional Clauses or If Clauses. •They are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled.

Conditional Sentences
•There are two kinds of conditional sentences: real and unreal.
•Real Conditional describes real-life situations. •Unreal Conditional describes unreal, imaginary situations.

•However there are three types of Conditional Sentences.

What do these sentences tell us about reality? •If you work hard, you‟ll succeed.
•If you worked hard, you would succeed. •If you had worked hard, you would have succeeded.

1st Conditional
A touch of reality…


Present simple
If I see him,
If I don‟t see him,

Main clause
I will give him the book.
I will phone him in the evening.

The order of the clauses can be reversed. In this case DO NOT use a comma.
I will phone him in the evening if I don‟t see him.

Use of Conditional type 1
•Conditional Sentences Type I refer to the future. •An action in the future will only happen if a certain condition is fulfilled by that time. •We don't know for sure whether the condition actually will be fulfilled or not, but the conditions seems rather realistic – so we think it is likely to happen

Finishgo away on holiday this year… sentences… the following 1. If I
2. 3. 4. 5. 6. 7. 8. 9. 10. If I lose all my money… If we get too much homework… If my friend gets into trouble.. If we finish early today… I‟ll eat my hat if… This school will have to close if… We will all be very happy if… I will be rather disappointed if… Will you help me if…


• Unless = If … not •If you don‟t run, you‟ll miss the bus. •Unless you run, you‟ll miss the bus.

2nd Conditional
There‟s still hope…


Past simple
If I won the lottery,
If I had a car,

Main clause
I would buy a house.
I wouldn‟t walk to school.

The order of the clauses can be reversed. In this case DO NOT use a comma.
I would read more if I didn‟t watch so much TV.

Use of Conditional type 2
• Conditional Type 2 is an unreal conditional. •The Unreal Conditional is used to talk about improbable conditions or impossible situations.

Please take a look at the example carefully…
•Conditional sentence •If John had money, he •True Fact 1 •True Fact 2

would buy a Ferrari. •John doesn‟t have money, He will not buy a Ferrari •John buys an ordinary car.

Please take a look at the example carefully…
•Conditional sentence •If I found her address, I •True Fact 1

•True Fact 2

would send her an invitation. • I don‟t find her address, I will not send her an invitation •It‟s difficult to find her address

Were instead of was
•In Conditional Sentence Type II, we usually use ‚were„ – even if the pronoun is I, he, she or it –. •We don‟t use was in Conditional Sentence Type II If I were you, I would tell her.

Finish the following sentences…
1. 2. 3. 4. 5. 6. 7. 8. 9. 10. If people had eyes in the backs of their heads… If cars didn‟t exist.. I would not tell him… If I were rich… If my best friend won the lottery… We would kill a dog… If we couldn‟t speak English… We wouldn‟t go to Paris… I would give you all my clothes… If schools didn‟t exist…

(unreal) Conditional

The land of regrets…


Past Perfect
If I had seen you,

Main clause

would have + past participle
I would have said hello.

If you had told me the truth, I would have forgiven you.

The order of the clauses can be reversed. In this case DO NOT use a comma.
I would have forgiven you if you had told me the truth.

Use of Conditional type 3
• Conditional Type 3 is an unreal past conditional.
•The Unreal Conditional is used to speculate about imaginary situations or to regret past events.

What have you not done?
•went to bed early last night? • dyed your hair pink? • travelled to Africa? • joined the army?

•4 things you haven‟t done (that you wish you had)
• 4 things you‟ve done (that you wish you hadn‟t)
