used to
固定词组
used to意为“过去常常”, 暗指现在已经不存在的动作或状态, 后接动词原形。
1. 否定句
used to的否定式通常为didn’t use to。如:
She didn’t use to have long hair.
2. 一般疑问句
含有used to的句子变为一般疑问句时, 可用“助动词Did+主语+use to do sth. ?”结构。肯定回答用Yes, sb. did;否定回答用No, sb. didn’t。如:
—Did you use to play the piano? —Yes, I did. /No, I didn’t.
3. 特殊疑问句
含有used to的特殊疑问句的结构为“疑问词+助动词did+主语+use to do...?”。如:
—What did you use to do? —I used to collect stamps.
4. 反意疑问句
如果陈述部分含有used to, 附加疑问部分通常使用助动词did来引导。如:
The house used to be a shop, didn’t it?
He didn't get enough sleep
他没有得到充足睡眠
例如:I used to smoke.
I didn't often smoke before/in the past
be used to sth习惯了某物
be used to doing sth 习惯了做某事
used to do sth 过去常常做某事
be used to do sth被用来做某事
use to有三种用法,
be used to被用来做……
used to do过去常常作某事
be used to doing习惯于做
所以可知didn't used to应该存在于used to do形式的否定中。
恩。。。以上是查到的资料。但个人认为,不存在。
