Объяснение:
Как же отличить форму времени глагола use от оборота used to? Рассмотрим примеры:
When I was writing my essay, I used information from the Internet. — Когда я писал сочинение, я использовал материалы из интернета.
I used to go to the library when I did not have Internet at home. — Я раньше ходил в библиотеку, когда у меня не было дома интернета.
Somebody used my toothbrush, it was wet. — Кто-то пользовался моей зубной щеткой, она была мокрая.
He used to brush his teeth three times a day. — Он раньше чистил зубы три раза в день.
В предложениях c глаголом use, глагол требует дополнения, выраженного существительным:
used information
used my toothbrush
Оборот used to согласуется не с существительным, а с глаголом:
used to go
used to brush
About the deciduous forests of Western Siberia
It so happened that in my home most of the West Siberian forests - small-leaved, consisting of birch and aspen. On the one hand, I like the birch forest. They are light and spacious, they are inhabited by a huge number of birds. In the birch forests lot of mushrooms and berries, which provide food for both people and animals.
But the birch does not give any fruit, nuts or acorns. Moreover, the maximum lifetime of a birch - only about a hundred years. In such a short period of birch does not have time to turn into a huge, dumpy, hollow tree and die ignominiously from the wind and rot. Therefore, age-old birch forests does not happen. And if there is no old-growth forests - that is not related tales and myths. In England there is Sherwood, Germany - Black Forest, in the Irtysh there is nothing (with apologies to singer Artynskogo boron comrade sibariana).
