56. Study the rules on the sequence of English tenses.

A BIT OF GRAMMAR

The Sequence of Tenses

If the verb in the principal clause is in one of the past tenses, a past tense (or Future in the Past) must be used in the subordinate clause.

If the past actions in both clauses principal and subordinate happened at the same time (simultaneously) we use Past Indefinite in both clauses or Past Continuous in the second clause if the action was in progress.

e.g. I knew this school was a strictly disciplined one.

The teacher thought (that) I was lagging behind my class.

If the action in the second (subordinate) clause was prior (happened before the action in the main clause) it is expressed by the verb in Past Perfect or Past Perfect Continuous.

e.g. He thought I had missed a lot of classes that term.

We were surprised that he had been disrupting lessons for such a long time and hadn’t got a due punishment yet.

If the action in the subordinate clause will happen after the action in the main clause we use Future-in-the-Past.

e.g. I knew he would miss my lecture because he was ill.

I thought you would be translating that article immediately after the class.

I expected you would have translated that article by the evening.

I guessed you would have been translating that article for an hour.

Exceptions to the Rules of Sequence of Tenses

      1. If the subordinate clause presents a generally known fact, it can contain a verb in either Present or Past Indefinite Tenses.

The teacher told the children that water boils/ boiled at 100 degrees centigrade.

      1. The modals must, should, ought are used in the subordinate clause independently of the tense used in the principal clause.

He tells (told) us that we must not cross the road against the red light.

      1. If the subordinate clause is attributive, comparative or adverbial clause of cause, its verb can be used in Present and Future Tenses when the main clause contains a verb in the Past Tense.

My brother told me about the book which you are reading .

He was not able to translate the article because he does not know English very well. It was not so cold yesterday as it is today.

57. Put the verbs in brackets in correct form.

1) He felt that somebody (watch) him. 2­) We wondered how much he (know). 3) I thought that as he (leave) next month he (come) certainly to say goodbye. 4) I asked her who else (come) to the party. 5)That is what I (tell) already to your friend. 6) I thought you (like) him. 7) It was clear that he (drop) something and now (look) for it under the table. 8) I looked at her again. She (not listen) to me, she only (pretend) to. 9) The explanation was that he (not expect) that sort of question. 10) Mother said that Aunt Bessie (come) for a visit and (bring) her little girl. 11) She said carelessly that nothing (make) her change her mind, once she (make) it but that at present she still (examine) the facts. 12)She knew she (be) right, (be) right from the very beginning. 13) I knew that Mary (go away) early next day, that she (pack) her things upstairs now, and that I probably never (see) her again.
