There be 用法

there be 是指某地有某人或者某物的存在，主要分清there 后面那个be用is 还是用
are，there is 后面接可数名词单数还有不可数名词，there are 后面接可数名词复数，疑问句是重点，主要就是对划线部分提问，我给你举几个例子
,there is a boy in the classroom. 对句中a 提问的话，
要用how many, how many boys(注意many 后加可数名词复数）are there in the classroom?
如果是对a boy 提问，
那么要用what, what's in the classroom?
复数的话，再来一个例子，
there are five boys in the classroom.
对five 提问：how many boys are there(are there不能丢）in the class room?
对five boys提问：what's in the classromm? 和单数句子一样，要注意，无论主语是单数复数，都用what's.
还有一种情况是不可数名词，再举个例子：
there is some water in the bottle.
对some 提问：用（how much因为水不可数）how much water is there in the bottle?
对some water提问：what's in the bottle?(和前面的一样哦，要注意）
There be＋代词或名词(短语)＋地点/时间状语
例如：
There is a desk and two chairs in the room.

“有某人在做某事”，要用“There be＋sb.＋doing sth.＋地点/时间状语”。
例如：
There are several children swimming in the river.河里有几个孩子在游泳。

There be句型表示“存在”关系，have表示“所属”关系，两者不能混合在一个句子中。
例如：
There is going to/will be a class meeting tomorrow.我们要说“明天有一个班会。”
