“there is a lot of”还是“there are a lot of "

题目

“there is a lot of”还是“there are a lot of "
看到一句子,有there is a lot of 什么的.
我是英语初学者,a lot of不是一些吗,为什么还用单数is?

答案

a lot of是口语和书面语中最常见的用语,它既可以修饰可数名词（相当于many）,也可以修饰不可数名词（相当于much）,通常用在肯定句中,例如：
There are a lot of books in the library．复数
{
There is a lot of people here at the small park.单数
此句因看a lot of后修饰是单数还是复数
