a large numberof和a large amount of的区别

①所能修饰的名词有区别

a large number of只可以修饰可数名词复数形式;a large amount of修饰不可数名词。

例句:I have a number of letters to write today.

今天我有好多信要写。

I spent a large amount of my time on this work.

我在这项工作上花了不少时间。

②谓语动词的形式有区别

a large number of 修饰的词作主语时谓语用复数形式;a large amount of 修饰的词作主语时谓语用单数形式。

例句:A large number of books are missing from the library.

图书馆的许多书不见了。

A large amount of damage was done in a short time.

短期内造成大量损害。

注意:The number of的意思是“...的数量”,修饰的可数名词作主语时谓语用单数形式;amounts of的意思是“大量的”,修饰的不可数名词作主语时谓语用复数形式,即谓语的数取决于 amount 的数。
