这是there be 句型 there be 句型表示某处有某物
there be 有 +某物+介词短语
be 是be 动词 根据后面的单复数 确定用is 和are 当后面紧跟的是单数就用is 紧跟的是复数就用are
There is a bag and two books in the desk
There are two books and a bag in the desk
Is there 和 are there 是 there be 句型的一般疑问句 变一般疑问句时 就把 is 或者are 提前就行了
Is there a bag and two books in the desk?
Are there two books and a bag in the desk?
