Reference explanation:
Correct answer: A
Knowledge: Inversion of conditional sentences type 3
Explain:
– Type 3 conditional is used to express a hypothesis that is contrary to the fact that happened in the past.
Formula: If S + had Ved/V3, S + would/could have Ved/V3.
Inversion form: Had + S + Ved/V3, S + would/could have Ved/V3.
– The future “wish” structure can be used to express a wish for something to happen or for something good in the future.
Formula: S + wish(es) + (that) + S + would + V.
