a large number of 和a large amount of的区别

　　a large number of和a large amount of意思都是“许多，大量”，用法上的区别如下：

1. a large number of 用来指可数名词的数量，后接复数名词。例如：

   He has planted a large number of trees. 他栽了很多树。

   There are a large number of books in this library. 这家图书馆有很多书。

2. a large amount of用来指不可数名词的量，后接不可数名词。例如：

   They moved in on a large amount of cultural relics during the period of the Second World War.  在第二次世界大战期间，他们掠夺了大量的文物。

   It will take a large amount of money to buy the apartment.买这栋公寓要花一大笔钱。

　　a large number of 修饰可数名词复数

　　a large amount of 修饰不可数名词
　　
　　首先，我们看看a large number of /a large amount of 与
the large number of /the large amount of 究竟差别在什么地方？ a
......强调重点在of后面的名词，表示“许多”，谓语动词的要求就看那个名词的性质；the......强调重点在of前面，即“number数
目”、“amount数额”，这两个名词一看就是单数，谓语动词的要求很快就确定下来了。例如What is the amount of my
bill? The total amount of the payment is＄4000. The number of the
accidents that happen in the home is [不是are] almost the same as those on
the road. The number of Rwanda refugees having returned home is [不是are]
approaching a million.
　　其次，我们再看看a large number of /a large amount
of后面的名词性质如何？a large number of students, books, animals等可数名词复数；a large
amount of information, money, work, help, pleasure
等不可数名词。这样，与之相关的谓语动词的语法要求很快也确定下来了。例如
There are a large number of students in the classroom. There is a large amount of water in the bottle.
最
后，补充说明：an amount of实际使用中还有两个变式（1）a large/certain/enormous amount
（2）amounts of 谓语动词的语法要求和标准式一样。a number of 的第一个变式是a
vast/countless/alarming/increasing number of... 第二个变式numbers
of字典里也有，但似乎不常用。
　　

都是"大量的"的意思

a large number of 的中心词都是 of 后面的名词，而且of 后面都是复数，动词也是用复数
意思分别是“一些。。。。。。。”，“大量的，许多的”
a large number of people have applied for the job

只不过都是amount是修饰不可数名词：
a large amount of+不可数名词，谓语动词用单数；
A large amount of students are playing games together.
