　　Scarf is used to taking a walk.(現(xiàn)在習慣于散步)

　　used to 的用法

　　否定式簡寫為usedn't) 過去經(jīng)常，以前常常

　　We used to go there every year. (我每年都去那兒。)

　　He is not what he used to be.

　　他已不是舊日的他了。

　　我們公司過去和他們的公司常有業(yè)務(wù)往來。

　　used to,would這兩個詞語都可以表示過去常做某事，有時可以換用。

　　used to do 強調(diào)整過去習慣性的行為或狀態(tài)，但是現(xiàn)在沒有這種行為或狀態(tài)了。因此，這個短語的內(nèi)涵是今昔對比。
