一个英语问题 急！在线等

was

应该填was吧！
我问过两位英语不错的老师，他们说谓语的单复数得看a large quantity of 或 large quantities of而定。
如果用 a large quantity of 谓语动词用单数，反之用复数，和修饰的名词无关！
高一英语出现过的，不过点拨出的题解释自相矛盾，我才去问的！
I hope that this imformantion will help you, may you succeed!

应该是were因为
a large quantity of 是大量的意思。a large quantity of mail bags 大量的邮包是复数

was
a large quantity 后跟单数
large quantities 后跟复数

a large quantity of mail bags ( ) found
应该填were!
这句话翻译成中文就是“发现了很多数量的邮包”。a large quantity of 既可以用来修饰可数名词，也可以修饰不可数名词，这就要看of后面所跟的名词了。在这句话中，用了bags,为复数，所以就要用were.

was
a large quantity of mail bags 这里只看a large quantity of
