Use the past perfect when the time of one past action is more past than that of another. Put the action which was completed first in the past perfect and the second action in the past tense.
Don't use the present tense and the past perfect in the same sentence. It would be incorrect to say: My brother says that he had not gone to the cinema last night.
Will changes to would in subordinate causes, when the verb in the main clause is in a past tense.
Don't use the past perfect unless there is another verb in the past tense in the same sentence.
As a rule, verbs denoting a state rather than an act have no continuous forms, like understand, know, believe, like, love, belong, prefer, consist, mean, hear, see, etc.
Use the simple past tense (and not the present perfect) for an action complete in the past at a stated time.
When a sentence has a word or a phrase denoting past time, like yesterday, last night, last week, last year, then, ago, etc., always use a simple past tense.
