代表数量的英文

hundred百、thousand千、ten thousand万、a hundred thousand十万、million百万、ten million千万、one hundred million亿、billion十亿

不同计数单位，按照一定顺序排列，它们所占位置叫做数位．在整数中的数位是从右往左，逐渐变大：第一位是个位，第二位是十位，第三位是百位，第四位是千位，第五位是万位，第六位是十万位，第七位是百万位，第八位是千万位，以此类推．同一个数字，由于所在数位不同，计数单位不同，所表示数值也就不同。 对于每一个数都应当有一个名称，以自然数来说，自然数是无限多的，如果每一个自然数都用一个独立的名称来读出它，这是非常不方便的，也是不可能做到的。为了解决这个问题，人们创造出一种计数制度，就是现在我们使用的十进制计数法。

英语中表示“许多”的词组很多，用法也不同。下面就由我为大家带来 英语 短语 集锦，大家生活中可以多用几遍，练一练语感。

表示数量

一、英语中表示“许多”的词组很多，按其用法可以分为以下三类

1、修饰可名词：many、a number of、 a few、many a、several等。many a 的意思相当于many , 但many a 后边接可数名词单数，如：

Many a student has such a question.许多同学有这样的疑问。

A number of students have passed the exam.许多学生都通过了考试。

Several days ago, I met him in the park.几天前我在公园里遇到了他。

2、修饰不可数名词：much、a great deal of、a large amount of等。

We can get a great deal of(a large amount of) information from internet.我们可以从互联网上获得大量信息。

3、既可修饰可数名词,也可修饰不可数名词：a lot of (lots of ); plenty of; a large quantity of 等。

Plenty of the water is polluted.许多水都被污染了。

Plenty of the rivers are polluted.许多河都被污染了。

二、few、little;a few、a little的用法：

1、few 和a few 都修饰可数名词。few意为“几乎没有”，表示否定;a few表示“有些、几个”，表示肯定;quite a few=many(修饰可数名词)表示“许多”。如：

I have eaten a few apples today.=I have eaten many apples today.

He has few friends.他几乎没有什么朋友。

2、little和a little都修饰不可数名词。little意为“几乎没有几个”，表示否定;a little表示“有些”。如：

I have little money.我几乎身无分文。

I have a little work to do.我有一些工作要做

quite a little=much(修饰不可数名词)表示“许多。

三、a number of 与the number of的区别：

a number of 相当于some，a few; a great/large number of相当于many，quite a few;the number of指的是“…的数量”。如：

The number of the students in our school is 5，000. 我们学校学生的数量是5000人。

A number of students have passed the exam.许多学生都通过了考试。
