谁能给我区分一下a little bit,a bit ,a bit of

a little = a bit
a bit和a little都作"一点儿"讲,但用法不同.
1)a bit和a little在肯定句中修饰动词、形容词、副词和比较级时可以互换,表示"一点儿"的意思.例如:
The speaker spoke up a bit/a little so as to make himself heard more clearly.
演讲者把嗓门提高了一点儿,以便使别人听得更清楚.
2)a bit和a little在否定句中的意思恰恰相反,not a bit相当于"not at all"(一点儿都不);not a little相当于"very(much)"或"extremely"(很、非常).例如:
She is not a bit tired.(=She is not tired at all.)她一点都不累.
3)a little可以直接作定语修饰名词,而a bit则要在后面加of构成短语才能作定语,两者都只能修饰不可数名词.例如:
There is a little/a bit of food left for lunch.
午饭只能吃剩下的一点食品了.
4)a bit of的另一种形式是bits of,a little则没有这种变体.例如:Besides this,he used part of an old army wireless set,and some bits of wood.除此之外,他还利用了一部分旧的军用无线电发报机的一部分零件和一些木片.
记住这些够你考试用了

二、a little / a bit / a little bit / for a bit 用法辨析
► 在肯定句中,a little和a bit意思相同：
This box is a bit heavier than the other one.
This box is a little heavier than the other one.这两句的意思都是：
这个箱子比那个箱子重一点.
再比如说“价格会上涨一点.”我们可以说：The price would jump a bit.也可以说：
The price would jump a little.
“还有点工作要做.”可以说：There is still a bit more work to do.
也可以说：There is still a little more work to do.
► not a bit和not a little 的意思正好相反.not a bit是“一点也不”的意思,和not at all意思相同；not a little的意思是“不是一点点”,和much意思相同：
I’m not a bit tired.(I’m not tired at all.) 我一点也不累.
I’m not a little tired.(I’m much tired.) 我很累了.（不是一点点累,是很累）
► a bit通常修饰表示“令人不快”的形容词,例如sad,silly,cold,hungry,angry,difficult,heavy,expensive等：
The song is a bit sad.这首歌有点伤感.
You might say I’m a bit silly.你可能会说我有点傻.
a little则无论褒贬都可以修饰：
Mary is a little older but a little more beautiful than Ann.玛丽比安年纪更大但是更漂亮.
Everyone seemed a little nervous.每个人看起来都有点紧张.
► a bit后面不能直接接名词,接名词要用a bit of的结构；a little则可以直接修饰名词：
This will add a little fun to the game.如果要用a bit来修饰fun,要用a bit of的结构：
This will add a bit of fun to the game.这可以使这个游戏更有趣一点.
当a little修饰的名词前有the,this,that,所有格等限定词时,也要用a little of的结构：
This remind me a little of those old sayings.这使我想起了那些古老的谚语.
► a bit 和a little不能用来修饰“形容词+名词”的结构.例如,heavy boxes这样的结构,就不能用a bit和a little修饰,不能说a bit heavy boxes；再比如hot weather,我们不可 以说a little hot weather.
► a little bit的意思是“一点点”,用法与”a bit”相同：
This is a little bit too difficult for me.这对我来说有点难.
Jack is a little bit selfish.杰克有点自私.
I speak a little bit of French.我讲一点法语.
This made me feel a little bit better about myself.这使我感觉好点了.
► for a bit的意思是 for a short time：
We talked for a bit.(We talked for a short time.) 我们谈了一会儿.
Please hang on for a bit.请等一会儿,不要挂断
