§ 22. The Past Indefinite and the Past Perfect.

            1. The Past Perfect is not used to denote a succession of actions. In this case the Past Indefinite is used.

The Past Indefinite is used with the conjunctions after; before, when if the relation between the actions approaches succession, i. e. when the idea of completion is of no importance.

He went on with his work after he had a short rest.

He had a short rest before he went on with his work.

When I wrote the letter, I posted it.

            1. Verbs of motion and sense perception such as to come, to ar­rive, to return, to see, to hear; in adverbial clauses of time are generally used in the Past Indefinite and not in the Past Perfect. The actions are practically simultaneous.

When he (Val) came down... he found his mother scrupulous in a low evening dress... (Galsworthy)

When he heard the first line of the poem, he recognized it at once.

When the completion of the action is emphasized the Past Perfect is used.

He knew the poem by heart when he had heard it several times.

The Future Perfect

§ 23. The formation of the Future Perfect.

              1. The Future Perfect is formed by means of the Future Indefinite of the auxiliary verb to have and Participle II of the notional verb.
