there be 句型中主语是什么?
there be 句型中主语是什么?
there be 句型中主语是：其后所接的名词或名词性短语等.
含有there be的句型（某处有某物）
肯定式
There is a student（主语） in the room.（地点状语）
There are two students（主语）in the room.（地点状语）
要点：
作谓语用的There is /are 要放在句首,而其主语则放在后面,is 后面接单数形式的主语；are 后面则应接复数形式的主语.
2 如果句中有若干个名词作主语,动词be常与后面主语中的第一个名词在数上一致：
例：There is a coffee shop,two bars and four restaurants in the hotel.
否定式
There is not a student in the room.
要点：
2 在be 动词（is /are）后加not即可构成否定.
2 还有一种否定形式,即在there is + no+单数名词或there are + no+复数名词：
例：There is no student in the room.
There are no students in the room.
疑问式
1．一般疑问句
Is there a student in the room?
Are two students in the room?
要点：
2 把be动词(is/ are)提到句首即可构成一般疑问句.
2 回答时用Yes或No：
例：Yes,there is./ No,there isn't.
2．特殊疑问句
How many students are there in the room?
要点：
2 how many 后跟复数名词.
2 特殊疑问句 = how many + 名词复数 + 一般疑问语序 (is/are there).
2 回答时不能用Yes或No,要给出具体的回答：
例：--How many students are there in the room?
--There are two.
注意：
2 there be常带有表示地点的状语,多由介词短语充当.状语的位置多在句尾,有时为了强调,也可置于句首：
例：On the wall there is a picture.
2 Some在否定句和疑问句中常变成any：
例：There are some students in the classroom.(陈诉句)
There aren't any students in the classroom.(否定句)
Are there any students in the classroom?(疑问句)
there
There be句型是一种典型的倒装句 一般是主语后置 或者说是表语前置
所以说，be后面的东西是主语
主格my you he
there be 是有的意思，主语是后面接的名词或名词性短语，比如there is a book on the ground. 就解释为地上有一本书。
there be翻译成有的意思．就是这儿有．
它后面的名词或名词性短语
是be 动词后面的名词或代词。
