Согласование времен в главном и придаточном предложениях

Roads and Railways

The transport network spreads into all sections of the country, but the web of railways and highways is much more dense in the eastern half of the United States.

In the early 1990s the United States had about 6,24 million km of streets, roads, and highways. The National Interstate Highway System, 68,449 km in length in the early 1990s, connected the nation's principal cities and carried about one-fifth of all the road and street traffic.

More than 188 million motor vehicles were registered in the early 1990s. More than three-quarters were cars — one for every two persons in the country. About one-fifth of the vehicles were lorries. Amtrak (the National Railroad Passenger Corporation), a federally subsidized concern, operates almost all the inter-city passenger trains in the United States; it carried more than 22 million passengers annually in the early 1990s.

1. What were the first routes in the US?

4. When did air transport start to gain importance?

GRAMMAR

В английском сложноподчиненном предложении с придаточным дополнительным (вопрос «что?», «кто?», «чего?» и т. д.) соблюдаются правила согласования времен в главном и придаточном предложениях. Эти правила сводятся к следующему:

1. Если глагол-сказуемое главного предложения стоит в настоящем или будущем времени, то глагол-сказуемое придаточного дополнительного предложения может стоять в любой временной форме, требуемой смыслом, например:

Не says you are right. — Он говорит, что ты прав.

Не will tell why he was not at school yesterday. — Он скажет, почему он не был в школе вчера.

2. Если глагол-сказуемое главного предложения стоит в прошедшем времени (обычно — в Past Indefinite), то и глагол дополнительного придаточного предложения должен стоять в одном из прошедших времен, в том числе — в будущем с точки зрения прошедшего (Future in the Past).

He said he would not go to school tomorrow. — Он сказал, что не пойдет в школу завтра.

При этом для обозначения действия, одновременного с действием, выраженным сказуемым главного предложения, употребляется Past Continuous (врусском языке — настоящее время) или Past Indefinite.

Не told me he was preparing for his exam. — Он сказал мне, что готовится к экзамену.

Для обозначения действия, предшествующего действию, выраженному сказуемым главного предложения, обычно употребляется Past Perfect. На русский язык глагол-сказуемое придаточного в данном случае переводится глаголом в прошедшем времени:

I didn't know he had left for Moscow. — Я не знал, что он уехал в Москву.

При указании определенного времени (in 1980, yesterday) предшествующее время выражается при помощи Past Indefinite. Например: I thought you were born in 1980.

Для выражения будущего времени с точки зрения прошедшего времени употребляется форма Future in the Past где вспомогательный глагол wil l меняется на would, которая на русский язык переводится будущим временем:

Не told me that he would meet me at the Institute. — Он сказал мне, что встретит меня в институте.
