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
