Not at all和certainly not的区别如题

Answer 1

区别是：
Not at all指的是一点也不，根本不。
certainly not指的是不，当然不行;决不。

例句辨析：

2、It's not at all certain whether I'll come tomorrow.

我明天还不定来不来呢。
3、I'm not at all secretive, and I'm pretty good at calling a spade a spade.

我不会遮遮掩掩，我喜欢直言不讳。

certainly not

2、I don't know just exactly how old his child is, but certainly not older than twenty.

他的孩子究竟多大我不清楚，反正不超过20岁。
3、She might be a little common at times, but she was certainly not boring.

Answer 2

not at all 一点也不，I donnot like him at all 我一点也不喜欢他。
certainly not当然不，I am certainly not in favor of that。我当然不赞成。

Answer 3
