a large amount of 和 large amounts of的区别

Answer 1

a large amount of 和 large amounts of的区别：
　　1.a large amount of +不可数名词，谓语动词用单数；
　　例：A large amount of money was spent on the bridge.
　　在这座桥上花了大量资金。
　　2.large amounts of+ 不可数名词， 谓语动词用复数。
　　例：Large amounts of money were spent on the bridge.
　　在这座桥上花了大量资金。
　　3.偶尔也可见到其后接复数可数名词的用法，但不算普通。如：
　　The shopkeeper had a large amount of oranges in his storeroom. 店主在货仓里存有大量橙子。——摘自《朗文当代高级英语词典》　　Even small amounts of these substances are known to cause skin problems. 我们知道这种物质即使是一丁点也会损害皮肤。——摘自《剑桥高阶英词典》

Answer 2

后面都接不可数名词。
a large amount of +谓语动词单数，
large amounts of +谓语动词复数

注意：an amount of,a(large,great)amount of,amounts of 修饰名词用作主语，其谓语的数取决于 amount 的数。如：
在这座桥上花了大量资金。
正: A large amount of money was spent on the bridge.
正: Large amounts of money were spent on the bridge.
（be动词和某些动词短语也可以是谓语动词；I see a girl.我看见一个女孩．“看见”"see"就是这个句子的谓语．而see也是个动词，所以就叫做谓语动词．She is very beautiful.她很漂亮．"is"就是这个句子的谓语，也是动词．）

Answer 3

a large amount of 和 large amounts of 都是大量的意思，修饰不可数名词。
amount 做“总量、总数”时是不可数名词；做“数量”时是可数名词，所以这里只是用了amount的复数形式,但意思差不多

Answer 4

没有什么区别,只是相当于 a lot of 和lots of一样.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.large amounts of+ 不可数n 谓语动词用复数.
