there be结构后接的句子成分是?是主语还是宾语?

主语哈.there be 相当于是一个倒装的成分.比如说桌上有一个苹果.中文中苹果就是主语.翻译成英语就是there is an apple on the desk.所以说是接主语.on the desk 是介词短语做状语.there是副词,所以不能做主语.======以下答案可供参考======供参考答案1:分情况，看语境，举个例子。there are 3 apples in my bag.其后是主语3 apples。there are 3 apples I can eat later。其后就是宾语3 apples了。供参考答案2:宾语 比如说最简单的句型There's a tree. Tree就是宾语。供参考答案3:是主语。There is a boy in the room可以说成A boy is there in the roomThere are some girls singing in the room可以说成Some girls are singing there in the room所以是主语，只不过是一种倒装。
