a lot of 后面可数或者不可数名词都可以接。
a lot of 和lots of意思基本上是一样的,就是many,much
首先要说的,是英文没有lot of,a lots of,a lots这说法.
A lot of和lots of都是“很多”的意思,用法有两点值得注意.
第一,a lot of和lots of都可用来说可数（countable）或不可数（uncountable）名词,而动词应用单数或复数形式,则看那名词而定,和a lot或lots无关.
例如“A lot of/Lots of money was lost.（损失了很多钱.）”一语,lots之后不用were；“A lot of/Lots of people were wounded.（很多人受了伤.）”一语,a lot of之后也不用was.
第二,many/much和a lot of/lots of意思相同,但语气上,many和much没有a lot of那么随便,a lot of又没有lots of那么随便.
所以,a lot of / lots of不宜用于谨严的写作,多见于口语；但问句、否定句口头上也多用many和much.例如甲问：“How much time have we?（我们有多少时间?）”乙可以说：“We haven't much time.（我们没有很多时间.）”或“We have a lot of/lots of time.（我们有很多时间.）”
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.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）
You know a lot/much about English names.你知道许多有关英语姓名的情况.（作宾语）
We see a lot of him these days.这几天我们经常见到他.（作宾语）
This is a lot.这真多.（作表语）
二、作副词短语,在句中作程度状语,表示“很；非常；常常”,修饰动词、感叹词、介词短语、形容词或副词的比较级,如：
It usually rains a lot/much at this time of year.每年这个时候都经常下雨.（修饰动词rain）
Do you wear your new watch a lot?你常戴你的新手表吗?（修饰动词wear）
Thanks a lot/very much ---that’s very kind.多谢,十分感激.（修饰感叹词thanks,thanks=thank you）
He is feeling a lot/much better.他感觉好多了.（修饰比较级better)
Your room is a lot bigger than mine.你的房间比我的大得多.（修饰比较级bigger）
三、a lot前可被such,what,quite,rather修饰,如：
I like him quite a lot.我非常喜欢他.
---How much money is left?---还剩下多少钱?
---Rather a lot.---还有相当多.
四、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.
五、用于固定搭配构成习语.
have a lot to answer for为糟糕的情况负责
Jerry’s got a lot to answer for.If it weren’t for him,Ann would never have left Denver.
杰里要为这一后果负责.如果不是为了他,安永远也不会离开丹佛（美国科罗拉多州）.

Leave Mum alone-she’s got a lot on her plate at the moment.不要管妈妈―——她眼下有太多的事要处理.
I can’t take a holiday at the moment; I’ve got a lot/far too much on my plate.我现在不能休假,我有太多的事要处理.
