UNIT 1

Mathematics is the science that draws necessary conclusions.

Benjamin Pierce

GRAMMAR: SEQUENCE OF TENSES.

REPORTED SPEECH

Согласование времен (Sequence of Tenses)

1.Если сказуемое главного предложения выражено глаголом в

настоящем времени (Present Simple, Present Perfect) или в будущем времени (Future Simple), то глагол в придаточном предложении употребляется в любом времени, которое требуется по смыслу.

 

he works there

работает

 

he is working there

 

 

I know

he worked there

работал

he was working there

 

 

 

he will work there

будет

 

he will be working there

работать

2.Если сказуемое главного предложения выражено глаголом в прошедшем времени (обычно Past Simple), то глагол придаточного предложения употребляется в одной из форм прошедшего времени

или будущего в прошедшем (Future in the Past).

 

he worked there

работает

 

he was working there

 

 

 

he had worked there

работал

I knew

he had been working there

 

he would work there

будет

 

he would be working there

работать

3. Изменение модальных глаголов при согласовании времен. can → could shall → should (совет)

may → might must → had to (пришлось, был вынужден) will → would

would, could, might, ought to, must (обязан)/mustn’t НЕ ИЗМЕ-

НЯЮТСЯ.

She reminded me that I ought to be

Она напомнила мне, что я

more careful.

должен быть осторожнее.

I didn’t understand why it was I who

Я не понимал, почему именно я

should do it.

должен все это делать.

Косвенная речь (Reported Speech)

Правило согласования времен действует и при обращении предложения в косвенную речь.

1.Повествовательные предложения в косвенной речи вводятся глаголами to say, to tell + косвенное дополнение без предлога to: he said that ..., he said to me that ..., he told me that ... .

Глагол в главном предложении,

настоящем времени.

Direct Speech

Jack says, "She knows the answer." Anna says, "We are leaving tonight."

Bob says, "I have read the story." Sue says, "They told the truth." Jim says, "I was thinking about it."

Greg says, "Dad will speak to you." Paul says, "He can swim here."

вводящий прямую речь, стоит в

Reported Speech

Jack says (that) she knows the answer. Anna says (that) they are leaving tonight.

Bob says (that) he has read the story. Sue says (that) they told the truth. Jim says (that) he was thinking about it.

Greg says (that) dad will speak to me. Paul says (that) he can swim here.

Глагол, вводящий прямую речь, стоит в прошедшем времени.

Direct Speech

Reported Speech

Present Simple

Past Simple

Jack said, "She knows the answer."

Jack said (that) she knew the answer.

Bob said, "I have read the story."

Bob said (that) he had read the story.

Past Simple

Past Simple/Past Perfect

Sue said, "They told the truth."

Sue said (that) they (had) told the truth.

Past Continuous

Past Continuous/Past Perfect

I said, "I was thinking about it."

Continuous

 

I said (that) I was /had been thinking

 

about it.

Past Perfect

Past Perfect (no change!)

Matt said, "I had read this book."

Matt said (that) he had read this book.

Past Perfect Continuous

Past Perfect Continuous (no change!)

Ted said (that) he had been doing it all

day."

day.

Future Simple

Future in the Past

Greg said, "Dad will speak to you."

Greg said (that) dad would speak to me.

Для передачи косвенной речи используется ряд других глаголов:

а) для сообщения информации: remark (отмечать), explain (объявлять), mention (упоминать), insist (настаивать), declare (объявлять), announce (объявлять), state (заявлять), promise (обещать);

б) следующие глаголы показывают, что далее последует ответ на уже высказанную реплику: answer (отвечать), confirm (убеждать), reply (говорить в ответ), object (возражать), agree (соглашаться), deny (отрицать), assert (утверждать), protest (выражать протест).

2.Общие вопросы вводятся в косвенной речи союзами if или whether, которые помещаются перед косвенным общим вопросом. Сам косвенный вопрос приобретает структуру утвердительного предложения.

Direct speech

The dean asked Lucie, “Do you live far from the university?”

My brother asked, “Can you answer the phone?”

Reported Speech

The dean asked Lucie if she lived far from the university.

My brother asked me if I could answer the phone.

Вместо глагола ask могут употребляться другие вводящие глаголы: want to know (хотеть знать), inquire (узнавать), wonder (интересоваться).

3.Специальные вопросы в косвенной речи вводятся вопросительными местоимениями, которые становятся союзными словами.

Direct speech

He asks me, “What book has she read since Monday?

He asked me, “What places have you visited?”

Reported Speech

He asks me what book she has read since Monday.

He asked me what places I had visited.

4.Повелительное предложение. Если прямая речь выражает

приказание, то глагол to say заменяется глаголом to tell (велеть, сказать) или to order (приказывать). Если прямая речь выражает просьбу, то глагол to say заменяется глаголом to ask (просить).

Следует иметь в виду, что после глаголов to ask, to tell, to order в английском языке всегда следует косвенное дополнение, обозначающее лицо, к которому обращена просьба или приказание, а само содержание просьбы или приказа передается глаголом в форме

инфинитива с частицей to.

Здесь также возможно употребление таких глаголов, как to invite (приглашать), to advise (советовать), to recommend (рекомендовать), to warn (предупреждать).

Direct speech

She said to him, “Come at five o’clock.”

The teacher said to me, “Don’t sit down.”

I said to her, “Please, bring me a glass of water.”

Reported speech

She told him to come at five o’clock.

The teacher told me not to sit down.

I asked her to bring me a glass of water.

5.Отступления от правил согласования времен.

А. Правило согласования времен не соблюдается, если придаточное предложение содержит универсальную (всеобщую) истину.

They didn’t even know that life has been developing on our planet for billions of years.

Они не знали даже того, что жизнь на нашей планете развивается миллиарды лет.

B.Если придаточное предложение содержит высказывание, которое говорящий считает истинным, безотносительно ко времени (пословицы, поговорки).

When he returned from France he

Когда он вернулся из Франции,

said that East or West home is best.

он сказал, что в гостях хорошо, а

 

дома лучше.

С. Если предложение в косвенной речи употребляется во II или III

типе условных предложений.

He said that if he were me, he would attend that conference.

Он сказал, что если бы он был на моем месте, он принял бы участие в той конференции.

6.Дополнительные изменения в косвенной речи. Личные,

притяжательные и указательные местоимения, а также наречия места и времени претерпевают следующие изменения при обращении предложений в косвенную речь.
