Unit 4 I used to be afraid of the dark. Grammar Focus
知识点拨
1. used to 的意思是“过去常常”，其中 to是不定式符号，其后加动词原形。
如: He used to live in Paris. 他过去常常住在巴黎。
2. used to 的句式变化:
肯定句 | 主语+ used to do sth. | |
否定句 | 主语+ didn't use to do sth. /主语+ usedn't to do sth. | |
一般疑问句 | Did +主语+ use to do sth.? | |
肯定回答 | Yes, 主语+ did. | |
否定回答 | No, 主语+ didn't. | |
3. 易混短语辨析: used to do sth., be used to do sth., be used to (doing) sth.:这几个结构容易混淆，下面我们通过例子以及相应练习，对这几个结构进行详细讲解。
(1) used to do sth.意思是“过去常常做某事”,暗含“现在已经不这样做了”之意。注意： to后面跟动词原形。
如: He used to be a teacher in our school. 他曾经是我们学校的一位老师。
You didn't use to smoke. 你过去不吸烟。
Did he use to walk to school? 他过去步行去学校吗?
(2) be used to do sth. 意思是“被用来做某事”。实际上这是 use 的被动语态形式, 即be +动词的过去分词+to do sth.不定式表示目的。
如: This knife is used to cut cakes. 这把刀是用来切蛋糕的。
(3) be-used to(doing) sth. 意思是“习惯于做某事”, 其中 to是介词, 后接名词或动词-ing形式。还可用 get used to 表示“渐渐习惯于⋯⋯”。
如: I am not used to my new job. 我不习惯我的新工作。
You' ll get used to your new job. 你很快就会习惯你的新工作的。
