VIII. Retell the text grammar: sequence of tenses

Согласование времен необходимо при передаче слов собеседника (при пе­реходе прямой речи в косвенную).

Наречия времени, места, указательные местоиме­ния меняются следующим образом:

yesterday - the day before, the previous day

today - that day, the same day

tomorrow - the day after, the following day

the day before yesterday - two days before

the day after tomorrow - in two days' time

last week - the week before, the previous week

now - then, immediately

next week - the week after, the following week

ago- before these - those

this - that here - there

Правила согласования времен обычно соблюда­ются в различных придаточных предложениях:

1. Если глагол в главном предложении стоит в форме настоящего или будущего времени, то глагол в придаточном предложении может быть в любом времени, необходимом по смыслу.

EXAMPLE: They wonder where I am (was, will be, have been).

We don't know what she thinks (thought, will think) about it.

2. Если глагол в главном предложении стоит в форме прошедшего времени, то в придаточ­ном предложении происходит сдвиг времен. В подобных случаях правила согласования вре­мен могут быть обязательными или же факуль­тативными.

Правила согласования времен обязательны, если действие придаточного предложения рассматрива­ется с позиции прошлого времени.

1. Если действие придаточного предложения про­исходит одновременно с действием главного пред­ложения, то в придаточном предложении упо­требляются Past Simple или Past Progressive не­зависимо от того, какое прошедшее время использовано в главном предложении.

EXAMPLE: Не didn't know where she was.

They noticed that he was smiling.

2. Если действие придаточного предложения предшествует действию главного предложения, то в придаточном предложении употребляются Past Perfect или же Past Perfect Progressive.

EXAMPLE: She had a feeling that she had been deceived.

I knew you had left Moscow two days before.

They understood what she had been doing.

3. Если действие придаточного предложение относится к будущему, то в нем употребляйте Future in the Past или же один из способов выражения будущего времени.

EXAMPLE: We hoped she would be back soon.

Nobody told me what would happen next.

He said she was going to have a snack.

They told him he was to do the work.

Правила согласования времен не соблюдаются в следующих случаях:

1. Если в придаточном предложении речь идет об общеизвестной истине или фактах, не требу­ющих доказательства и остающихся верными вплоть до момента речи.

EXAMPLE: My father explained to me that the Earth is moving and that it is round.

The child was told that the sun rises in the East.

Our geography teacher told us at the lesson that there aren't any unknown islands left on the Earth.

2. С модальными глаголами must, should, ought to правило согласования времен также не со­блюдаются.

EXAMPLE: I wrote that I must see him.

He said he should be more careful.

Those people advised me that I ought to see a doctor.

3. Если говорящий ссылается на слова собе­седника, которые только что были сказаны.

EXAMPLE: Mary: Don't leave,

Bess: I'll make a cup of coffee for you.

Bess to Tina: Mary said she will make a cup of coffee for us.

Sarah: What's the weather like in Moscow?

Ann: Oh, it's snowing heavily.

Sarah to Bell: Ann said that it is snowing heavily in Moscow.

4. Простое прошедшее время (Past Simple) в придаточных предложениях времени, вводимых союзами when и since, не претерпевает ника­ких изменений.

EXAMPLE: Michail said, "I haven't met Susan since we parted." - Michail said that he hadn't met Susan since they parted.

5. Прошедшее продолженное время (Past Pro­gressive) не подвергается сдвигу времен.

EXAMPLE: He remarked, "When I came in, she was crying".

He remarked that when he came in, she was crying.

Monica said, "When I came to the party, everybody was dancing." - Monica said that when she came to the party, everybody was dancing.

6. При передаче последовательных событий, где указывается конкретная дата, прошедшее вре­мя глаголов не подвергается сдвигу времен.

EXAMPLE: Не said that he was born in Kaluga in 1980 and soon the family moved to Moscow. She said she graduated from University in 1995.
