at all 是不是有两个意思? 我记得课本上是 毕竟；终究 的意思. 而新概念英语上说是 根部不 的意思. 请解释一下at all 得所有意向及其用法,再各造一个句子. 英语

【答案】 1. at all用在否定句中:
1) not...at all=not a bit 根本不
如: I'm not hungry at all.
2) Not at all. 不用谢/没关系
如: Thanks. Not at all.
I'm sorry. Not at all.
2. at all用在疑问句中,表示到底,究竟=on earth
如: Did you sleep on the plane at all?
3. at all 用在肯定句和条件从句中,表示居然,竟然；既然
如: If you want to do it at all, do it well.
He is very lazy, but he passed the exam at all.
4. after all 才是毕竟；终究的意思(楼主记混了)
