关于英语There be+单数复数问题

There is/are a ball and a book on the desk.
There is/are a computers and 22 desks in our classroom ?

一个句子中有一个复数和单数或一个单数复数的话，前面开头的There be用are还是is？是看BE后面的单数还是复数决定还是如果其中有复数就要用are了？
_____ the science lab in fornt of the library?

Answer 1

是的，如果THERE BE后面的名词是单数的就用is.如果后面是复数的就用are

就近原则.
即与be接近的名词的单复数形式相一致.
如:There is a computers and 22 desks in our classroom ?
There are 22 desksa and computers in our classroom ?
.

就近原则
看后面的是单数还是负数
