在日常交流中，外国人常说的“not half”千万别理解成“不是一半”，否则就会贻笑大方啦。请看：
“not half”有两个非常矛盾的含义：
（1）第一个含义： “not half”英文解释：used in spoken English to express a positive statement more strongly，中文即“（加强肯定语气的口语表达）非常，很,完全地，彻底地”，相当于：quite , very, very much, a lot, to a considerable degree， completely， absolutely 或 entirely .“ 此时在英语口语中可以用在形容词（副词）或名词的前面，起到加强语气的作用（尤其在英国英语中）。如：
It’s not half cold today. 今天很冷。
It isn’t half windy.风刮得很大。

=She quite swears
（2）第二个含义：not at all 中文即“一点也不，一点都不，根本不是，远远不”，如：
