________(二)
________(三)
________(四)
a bit； a little； a little bit
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。
5) 1）a little=a bit=a little bit +形容词；2)a little=a bit of +名词
二、a little / a bit / a little bit / for a bit 用法辨析
1）在肯定句中，a little和a bit意思相同：
This box is a bit heavier than the other one.
= 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“价格会上涨一点。”
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.
1） not a bit和not a little 的意思正好相反。not a bit是“一点也不”，等于not at all；not a little/ few的意思是“不是一点点”，和very much；extremely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）
2）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; a little则无论褒贬都可以修饰：
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。
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。
3）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：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 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。
This remind me a little of those old sayings. 这使我想起了那些古老的谚语。
4）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。
5）for a bit和for a little意思相同，相当于for a while或for a short time，可互换。
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
练习：用a bit或a little填空。
1. There is _________ time left.
2. I would like you to stay for _________ if you have time.
3. This will give us a _________ of time.
4. He went to sleep soon, for he was not _________ tired.
5. I don't want to stop to have a rest, because I am not _________ tired.
Key：1. a little 2.a bit, a little 3.a bit 4.a little 5.a bit
