如题所述

Answer 1

I used to live in South America when I was a little boy.

2.[被用来]sth is used to do sth某物被用来做某事

目的“用来做某事”。

旧牛仔裤现在被用来擦桌子。

3.[用作]use for
例句：We used the seal's fur for coats. 我们用海豹皮做大衣。

4.[用光]use up
例句： By this time he had used up all his savings. 到这时, 他的存款已全部用完。

5 [习惯做某事]be used to sth./doing sth.

就这些吧，我好像只能想起来这么多。
