请问谁知道英语中的much,many 和a lot of 的用法区别,
我也知道much 修饰可数名词，many 修饰不可数名词，a lot of 可数不可数都可以，关健它们三个在应用时有什么具体的区别

Many和Much用法
①many和much都作“许多”解,但many用于修饰可数名词,而much修饰不可数名词.例如：
1.China has many oil fields.中国有许多油田.
2.In our view,there is much oil here.在我们看来,这里有许多石油.
② 代词many和名词much用法举例：
1.Many of the students want to sum up the past experience before going on.许多学生（原意为：学生中间有许多人）要总结一下过去经验在继续干.
2.Much of the waste acid is utilized.废酸中大部分被利用了.
③“much（副词）+比较级”作“……得多”
1.The sun is much large than the moon.太阳比月亮大得多了.
2.This problem seems much more difficult than that one.
这道题似乎比那道题难得多.
3.We turned back a much larger enemy force.我们把力量强得多的敌人顶了回去.
④ 副词much修饰动词、过去分词时作“十分”
1.We all love Beijing very much.我们大家都非常热爱北京.
2.We are much interested in heat utilization.我们对热量利用十分感兴趣.
注：上述两种句子,一般不能用very代替much.
有时much也可修饰作表语用的形容词：
It is much the same.差不多相同.
⑤ many和much的一些常用词组：
many a time 许多次 how many books 多少书 how much water 多少水
as much (many) 同样多 as much (many) as 像……那么多
倍数+as much (many) as… ……的……倍（那么多） much less 何况（用于否定）
much more 何况（用于肯定）
注1：much和many的比较级和最高级都是more和most,“more（或most）+形容词或副词原级”还分别构成比较级和最高级.如：more useful较为有用的；most widely 最广泛地.
注2：“many a+可数名词单词”用法特殊,举例如下：
1.Many a worker often shows concern for us.（注意谓语用第三人称单数形式）许多工人经常关心我们.
2.Many a time have they been to Beijing.（注意Many a time作状语位于句首时,后面要引起主语、谓语颠倒现象,因为many a time和often近义,often位于句首时也引起主语、谓语颠倒.）他们去过北京多次.
much加不可数名词,如much milk
many加可数名词复数,如many apples
How many加可数名词复数,如How many pears
How much加不可数名词,如How much water
How much也可用于问价钱,如How much are the apples?意思是这些苹果多少钱?这是How many与How much的最大区别
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.
