【问】 (A) I used to work hard.
 (B) I’m used to hard work.
 句(A)与句(B)中的used to有什么区别?
 【答】 在句(A)中，used to指的是过去的习惯性动作，目的在于与现在形成对照。I used toworkhard.是说“我过去常常努力工作”，暗含的意义是“我现在不努力工作了”。在表示过去的习惯性这一点上，与would的意义相同。从形态上看，used to是个情态动词，其中的to是不定式符号，后面跟的是动词不定式(work)。

 你过去住在伦敦，是不是?
 3. We used to get up at 5 a. m. every morning all throughout the summer. (CGEL)
 过去整个夏天我们都是每天早晨5点起床。
 在句(B)中，used to +NP结构之前必须使用连系动词be，get，become等。在意义上相当于accustomed to(习惯于)。从形态上看，used是个分词型形容词，to是个介词，因此后面
 只能跟名词、代词或动名词。
