UNIT 9 GRAMMAR : CONDITIONAL TYPE III
Conditional Sentences Type III refer to situations in the past. An action could have happened in the past if a certain condition had been fulfilled. Things were different then, however. We just
imagine, what would have happened if the situation had been fulfilled.
EXAMPLE :
If he had stayed at home , he would not have caught the virus.
(the reality is that he didn’t stay at home, so he caught the virus.)
FORM:
If clause : main clause :
[If + past perfect ]
,
[ would /could/might + have + past participle ]Or :
[would /could/ might + have + past participle ] + [ if + past perfect ] EXAMPLE :
I could have contacted him if I had kown his address.
REMEMBER :
Instead of if not we can use unless . EXAMPLE :
She would have come with us if she hadn't been so ill.
She would have come with us unless she had been so ill.
