表示數(shù)量的：
一、英語中表示“許多”的詞組很多,按其用法可以分為以下三類：
1、修飾可名詞：many、a number of、 a few、many a、several等.many a 的意思相當于many ,但many a 后邊接可數(shù)名詞單數(shù),如：
Many a student has such a question.許多同學有這樣的疑問.
A number of students have passed the exam.許多學生都通過了考試.
Several days ago,I met him in the park.幾天前我在公園里遇到了他.
2、修飾不可數(shù)名詞：much、a great deal of、a large amount of等.
We can get a great deal of(a large amount of) information from internet.我們可以從互聯(lián)網(wǎng)上獲得大量信息.
3、既可修飾可數(shù)名詞,也可修飾不可數(shù)名詞：a lot of (lots of ); plenty of; a large quantity of 等.
Plenty of the water is polluted.許多水都被污染了.
Plenty of the rivers are polluted.許多河都被污染了.
二、few、little；a few、a little的用法：
1、few 和a few 都修飾可數(shù)名詞.few意為“幾乎沒有”,表示否定；a few表示“有些、幾個”,表示肯定；quite a few=many（修飾可數(shù)名詞）表示“許多”.如：
I have eaten a few apples today.=I have eaten many apples today.
He has few friends.他幾乎沒有什么朋友.
2、little和a little都修飾不可數(shù)名詞.little意為“幾乎沒有幾個”,表示否定；a little表示“有些”.如：
I have little money.我?guī)缀跎頍o分文.
I have a little work to do.我有一些工作要做
quite a little=much（修飾不可數(shù)名詞）表示“許多.
三、a number of 與the number of的區(qū)別：
a number of 相當于some,a few； a great/large number of相當于many,quite a few；the number of指的是“…的數(shù)量”.如：
The number of the students in our school is 5,000.我們學校學生的數(shù)量是5000人.
A number of students have passed the exam.許多學生都通過了考試.
