_____(be)thereanybooksinthebox?N?
_____(be)there any books in the box?No, there ____(be) only two balls.
答案为Are和are 因为there be句型中be动词的单复数形式要向其后最近的名词的单复数保持一致，该题第一空后名词是books，所以应是Are。第二空后名词是two balls，所以也应是are。注意下句中be的单复数形式：There is a book，a pencilbox and several exercise books on the desk。但：There are several exercise books，a book and a pencilbox on the desk。希望对你有所帮助。
