问几个关于英语的问题
1、a bit和a little的区别
2、a few和few,a little与little的区别（few和little的用法）
3、May be与Maybe的区别,Let's和Let us的区别
看见这么多意思差不多的词表惊讶……我记什么知识都很容易弄混……
还有再问下通常副词用于什么情况啊？除了修饰动词还有其他情况吗？动词后若有其他的单词那还用副词吗？（汗，我英语不肿么好）

few,a few,little,a little
虽然都表示“少”,但
（1）few,a few是可数的,little,a little是不可数的.
（2）a few,a little含肯定意味,few,little含否定意味.这里所谓的“肯定意味”和“否定意味”应该这样来理同样是半杯水,口渴者会认为：There is little water in the glass.而不口渴的人则会认为：There is a little water in the glass.
一：
1．few修饰可数名词复数.
2．few (= not many; hardly any)含否定意义；a few (= some; several; a small
number of) 含肯定意义.
3． not a few = no few = quite a few = a good few = many.
4． 当 few受 every,last,past,next,some,very等词所修饰时,表示肯定意义,few之前不再有冠词.如：
In the last few minutes,he checked up his paper again.
It took us some few days to repair the machine.
They are very few in number.
There were too few of them.
He goes to see his grandma every few weeks.
5． 在非正式文体中很少见,一般用或代替,如：
Only a few people attended the meeting.
另外,little / a little
Little remains to be done about it.(作主语)
A little remains to be done.
Please give me a little.(作宾语)
He knows a little of everything.
There is very / but little time left.(作定语)
Don’t worry; you still have a little time.
1． little修饰不可数名词,表示“量”.
2． little含否定意义(反义词：much)；a little含肯定意义(反义词：none).
3． 在非正式英语中,一般很少用little,常用not much,only a little来代替,如：
We haven’t got much money / time.
maybe是副词,只能作句子中的状语.例：或许他是个学生.Maybe he is a student.
而may be则是两个词,may是情态动词,使用时必须后接谓语动词；他大概是个学生.He may be a student.
详解
1.maybe 副词,意为“可能”、“也许”,通常用于句首,有时也放在句中或句末；may be 是情态动词“may”加动词“be”,意为“可能是”、“可能在”等.比较以下各组句子,含义相同,但结构不同：
你也许是对的.
正：Maybe you are right.
正：You may be right.
他可能迷路了.
正：Maybe he has lost the way.
正：He may have lost the way.
正：It may be that he has lost the way.
2.副词 maybe 可单独用作答语,但 may be 不能这样用.如：
A：Do you think he’ll come back?你认为他会回来吗?
B：Maybe.(Maybe not.) 也许会回来吧(也许不会回来吧).
Let's和Let us有什么不同
在"Let's"句型中,反意疑问部分要用shall we或shan't we,表示建议；而在”Let us/we”句型中,反意疑问部分要用”will/won't you”,表示请求．
摘＜英语周报＞上面的一段话．
Let's,Let us
1.Let's是Let us的缩写.包括说话人和听话人双方在内,含有催促、建议或请对方一起行动的意思.在听话人表示赞同建议时可只用Let's.如：
---Shall we go by train?
---Yes,let's.
2.当请求对方允许自己（第一人称复数）做某事时,要用Let us,这里的 us 不包括听话对方在内,不能缩写为Let's.
如两个同学对老师说：
Please let us remove the bookshelf for you.
让我俩给你移动一下书架.
3.两者在构成附加疑问句时,方法不同.如：
Let's go to see the film,shall we
咱们去看电影,好吗?
Let us go to see the film,will you?
让我们去看电影,好吗?
说明：从以上两句可以看出,当Let's引导祈使句,包括对方在内时（Let us也可）,疑问句用shall we,表示征求意见或提建议,当Let us引导祈使句不包括对方在内时,疑问句用will you,表示委婉、客气的请求.
