Conditional forms

After today's lesson

- I know what conditional sentences are

- I can use the zero, first, second and third conditional 

Conditionals

If this happens, that happens

If I do this, that will happen.

If we did this, that would happen

If he had done this, that would have happened. 

Zero Conditional

	if clause	main clause
General truths or consequences of a situation	present simple	present simple
If a town has clean air, the residents are healthier.	If a town has clean air	the residents are healthier

First conditional

	if clause	main clause
Possible future situation, suggestions, advice, threats and promises	present simple	will/won't + infinitive (whole verb)
If more people use the new bus service, there will be fewer traffic jams.	If more people use the new bus service	there will be fewer traffic jams

Second conditional

example sentence	if clause	main clause
Unlikely/unreal situations in the present or future	past simple	would(n't) + infinitive (whole verb
If I lived closer to the cinema, I would go more often.	If I lived closer to the cinema	I would go more often

Third Conditional

	if clause	main clause
Regrets, criticisms and unreal situations in the past	past perfect (had/hadn't + past participle)	would(n't) have + past participle (voltooid deelwoord)
If they hadn't built that block of flats, we would have had a sea view.	If they hadn't built that block of flats	we would have had a sea view

Name	If-clause (condition)	Main clause (Result)	Use
Zero conditional	If + present simple	present simple	General truths, scientific facts - always true
First conditional	If + present simple	will / can + infinitive	Likely events in the present or future
Second conditional	If + past simple	would / could + infinitive	Unlikely / unreal events in the present or future
Third conditional	If + past perfect	would have / could have + past participle	regrets, criticisms, unreal situation in the past

When to use which tense 

1. Figure out where the verb tense is missing: is it in the if-clause (condition) or the main clause (result)? 

2. In the if-clause, only three tenses can occur: a present simple, a past simple or a past perfect.

3. In the main clause (result) there are four possibilities: a present simple, a future with will, a future with would, a future perfect 

If + present simple	present simple
	will + infinitive
if + past simple	would + infinitive
if + past perfect	would have + past participle

if + past simple + would/could/might - for hypothetical situations in the present or future, suggestions and advice

if/unless + present simple + will/ won't might - for a future possibility

if + past perfect + would have + past participle - for hypothetical situations in the past or regrets about the past

if/when + present simple + present simple - for general truths or the result of a situation/action
