　　 英语四级语法用法辨析：a bit和a little的区别
　　1. 当它们用作定语，表达“数量”时，a bit后要加of，a little 则不用。例如： She ate a bit of bread for lunch. She ate a little bread for lunch. 她午饭就吃了一点点面包。
　　2. 但是，一旦否定，not a bit 和 not a little的意思就大不一样了，甚至相反。 not a bit 意思是“一点也不”，相当于not at all，not in the least之意。例如： He is not a bit like his father.他一点也不像他父亲。 Are you hungry? --- No, not a bit. 你饿了吗? 不，一点也不饿。 She is not a bit happy.她很不开心。 not a little意思是“非常，很”，相当于 very (much), a lot 之意。例如： He is not a little like his father.他很像他的父亲。

　　I am not a little surprised at the news. 我对这个消息深感惊讶。 The boy was not a little worried because he hadn't heard from her parents for a long time. 那个男孩很担心，因为好久没收到父母的来信了。
