KEYS file 3B: Help with Grammar- Third conditional

Exercise 5 page 26 - student's book
a) 1. No, she didn't     2. No, she didn't

• We use the third conditional to talk about imaginary situations in the past
• The third conditional often describes the opposite of what really happened: If the woman had shot the men, she'd have been in serious trouble.( The woman didn't shoot the men, so she didn't get in serious trouble.

b) We use the Past Perfect Simple in the if clause. We use 'd (=would)/wouldn't + have+ past participle in the main clause.

Remember! Third conditional: 

if + subject+ Past Perfect Simple ( if clause), subject + 'd (=wouldn)/wouldn't +have +past participle in the main clause. ( we use a comma when the if clause is first)

• We don't usually use would in the if clause: 
• If I'd known, I'd have helped. not If I would have known, I'd have helped

c) 1. We also use could and might in the main clause to mean 'would perhaps' ( sentences 2 and 4 in 4a))

2. No, it isn't. As with other conditionals, the if clause can be first or second in the sentence: I wouldn't have been too happy if the car alarm had woken me up. 

3. We make questions in the third conditional with:

• ( question word) + would+ subject+ have+ past participle....if  + subject+  Past Perfect Simple. For example: What would the owner of the car have done if he'd seen him?.

Remember! We can also use imagine and suppose in third conditional questions: 

Imagine/Suppose he'd seen you, what would you have done?
