alotof,lotof,lotsof和aliffle,liffle的区别
a lot of = lots of,可修饰可数或不可数名词,意为“许多”,“大量的”,相当于many或much.a lot,a lot of,lots of通常用于肯定句,否定句中一般用many或much,如：
There’s a lot of work to do and a lot of people have been sent there.
有许多事情要做,许多人已派去那里了.
a lot是口语中的一个常用词组,多用于肯定句,有时也用于疑问句.(后面不接名词).其主要用法有如下几点：
一、作名词短语,表示“很多；多量”,在句中作主语、宾语或表语,其后常有动词不定式短语作后置定语,
如：
Sometimes we have very little snow,but sometimes there’s a lot.有时我们这儿雪很少,有时却又很多.（作主语）
There is a lot to see at the party.聚会上有许多可观赏的东西.（作主语）
He’s given her a lot to eat.他给了她许多好吃的东西.（作宾语）
This is a lot.这真多.（作表语）
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.
