bit
1.a bit, a little和a little bit意思相同，都是“一些（地）”。但not a bit和not a little bit是“一点也不”，not a little是“很”。比较下面三句：
- He was not a bit sorry.（他一点也不抱歉。）
- Hs was not a little bit sorry.（他一点也不抱歉。）
- He was not a little sorry.（他很抱歉。）
not a bit和not a little bit两种表达方式里的not可以分开，如He did not feel a bit sorry和He did not feel a little bit sorry。not a little里的not不可分开，如不可说He did not feel a little sorry，该说He felt not a little sorry。
