Question

there are some desks and chairs 改为一般疑问句

Answer 1

Are there any desks and chairs?
注意：
1. 含be动词的陈述句变一般疑问句时，是将be的具体形式提前至句首。又如：
He was a teacher ten years ago.
… Was he a teacher ten years ago?
2. 肯定句中的some在疑问句及否定句中要改成any。又如：
I have some good books.
一般疑问句：Do you have any good books?
否定句：I don't have any good books.

Answer 2

there are some desks and chairs 改为一般疑问句是直接把 are 提到句子开头，some改为 any
即
Are there any desks and chairs？
