When the verb in the main clause is in the past tense, use a past tense in subordinate clauses.
This rule doesn't apply (1) to verbs within quotations, (2) to facts that are true at all times. We say:
1. She said, 'I am waiting for your answer'
2. He said that London is a great city
Will changes to would in subordinate causes, when the verb in the main clause is in a past tense.
Express a counterfactual (that didn't happen) condition by the past perfect and use the past conditional in the main clause. This use of the past perfect doesn't indicate a time but an impossible happening.
Don't use the past perfect unless there is another verb in the past tense in the same sentence.
