优质解答

所以啊.选D
1.a little 和a bit 都有"一点儿"之意,都可以用作副词,用来修饰形容词、副词以及动词,充当状语,这时两者可以互换使用；
它们也可以用作形容词,修饰不可数名词,这时有一点区别：a little 可修饰名词,但a bit 后面必须加上介词of后才能再接名词.
与not连用时,它们的意义完全不同：not a little 意为"非常"、"很",相当于very;not a bit 意为"一点也不",相当于not at all.例如：
This book is a little/a bit difficult for me.对我来说,这本书有点难.
Why don't men do a bit of housework?为什么男人不做一点儿家务呢?
The weather is not a bit cold today.今天天气一点也不冷.
She is not a little good at English.她很擅长英语.
2.a little bit固定词组 ph.有点;有几分.如：
I am a little bit busy right now ,can we talk later?
我现在有点忙,能等一下再说吗
