many 与much 修饰比较级时 怎样区别

many不能修饰比较级；much 修饰一些形容词的比较级.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,分别详见第337页和225页.“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
