a bit

　　【世博精解】

　　1)a bit只修饰处于补足语位置上的形容词，不能修饰名词短语前的形容词，这时的用法与a little一样。如：

　　The box is a bit/a little heavy.

　　The weather is a bit/a little hot.

　　(a bit/a little heavy box(es)/hot weather, etc.错误用法)

　　2)a bit不能直接修饰名词，须用a bit of,(但a little则可以)如：

　　I have a little money with me.

　　I have a bit of money with me.

　　(I have a bit money with me.错误用法)

　　3)习惯用语after a bit, for a bit,和in a bit在口语中均用来表示“a short time”的意思。如：

　　I am going to sleep for a bit.

　　I will be ready in a bit.

　　4)a bit作程度副词用在否定句中，与at all同义；用在肯定句中与a little同义。(但a bit不管指何种意义，都是非正式用法)如：

　　They don't like his attitude at all/a bit.

　　We will try and help her a little/a bit.

　　They weren't a bit aplogetic.

　　(They weren't apologetic at all.正式用法)

　　*注意：

　　not a bit和not a little的意义正好相反。not a bit是not at all的非正式用法。但not a little是委婉语，作“much”解释，两者切勿弄错了。

　　试比较：

　　He is not a bit tired.(他一点也不累)

　　He is not a little tired(他相当累)

　　He was not a bit annoyed.(他一点也不烦恼)

　　He was not a little annoyed.(他相当烦恼)
