create unreal past sentences from these: I wasn’t at home. I wanted to go with them. We didn’t have her address. She didn’t speak perfect Spanish. You weren’t listening to me. I knew the answer. He had to work hard. You were there. He wasn’t there. This class was supremely intelligent. I didn’t pay attention to the other cars. She didn’t see her friend. It was Monday. I didn’t come to university by scooter.
what about ‘wish’?
3 possible constructions:
I wish it were Friday.
I wish I had known about the party.
I wish my neighbours would shut up.
unreal present I wish it were Friday. unreal past I wish I had known about the party. possible but remote future desire I wish my neighbours would shut up.
unreal present past subjunctive I wish it were Friday. unreal past perfect subjunctive I wish I had known about the party. possible but remote future desire ? I wish my neighbours would shut up .
compare
I hope my neighbours (will) shut up. I want them to shut up maybe they will.
I wish my neighbours would shut up. I want them to shut up but I expect that they’ll continue to make a noise.
I wish my neighbours would shut up. ?
what is the present situation?
M y neighbours won’t shut up. won’t = they don’t want to shut up
present fact My neighbours won’t shut up. 1. + ive <-> - ive They will shut up . 2. go one tense back (past subjunctive) They would shut up . 3. add context I wish (that) t hey would shut up .
I wish my neighbours would shut up. ‘would’ is the past subjunctive of ‘will’ IT IS NOT the conditional!
