a variety of和 varieties of后面谓语用单数还是复数
我问的不是名词但是还是复数，是后面的谓语用什么形式
答
a variety of：各种各样 后面跟可数名词的复数形式或不可数名词。
He didn't come for a variety of reasons.他因种种原因没来。
varieties of后面只加可数名词的复数形式，两者没什么区别，意思是“各种各样的……”

For example:1.There is a variety of books to choose from.2.Varieties of books are being sold at this bookshop.如果是a variety of谓语动词用单数.如果是varieties of谓语动词用复数.
