There is an apple,two bananas and some oranges on the plates.主语是哪个?怎么判断

主语是:an apple,two bananas and some oranges
There be 句型是一个约定俗成的倒装句(倒装已成习惯用法).
这里"there"是引词无词义
谓语(be动词)
主语:an apple,two bananas and some oranges
状语:on the plates
原句还原成陈述句如下:
An apple,two bananas and some oranges are on the plates.
可以看出同样是表达某物在某处,但陈述句远不及There be 这种约定俗成的倒装结构给人的那种形象而又生动的感觉.
补充:There be 结构中的谓语动词,采用就近原则
如:There "is" an apple,two bananas .
There "are" two bananas ,an apple.
If you still feel confused ,leave a massage please

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)
