use的用法 used up be used to do (doing)

辨析:

used to 意为“过去经常”,其中的 to 是不定 式符号，而不是介词，所以其后只接 动词原形(不能接动名词)。如： 他过去一直住在巴黎。He used to live in Paris.

注：used to 通常不能与表示具体次数(如 twice, three times 等)或一段时间(如 three months, five years 等)的词或短语连用，但是它却可以与 always, often 等表示经常性意义的副词连用。 如：我去过巴黎 3 次。I went to Paris three times. I used to go to Paris three times. home

be/get used to sth./doing sth.. 习惯于……其中的 to 是介词，所以其后要接名词 或动名词(不能接动词原形);若要强调从不习惯到 习惯的过程，可用 get, become 等代替动词 be。 如：

He is used to looking after himself. 他已习惯于自己照顾自己。 I’m sure I’ll get used to the hard work.

我相信我会习惯这艰苦工作的。home

be used to do 被用来做……其中use表“使用” 之意，是被动语态形式，to是动词不 定式符号。

例如：Wood can be used to make paper.

树木可以用来造纸。

home
