there is a pen on the desk?there——主语,is——系动词,a pen——表语而“on the desk”——在句中担当什么成分,修饰哪个语是不是做“地点状语”用于修饰全句的吗？我感觉它肯定不是修饰“表语”

Question

there is a pen on the desk?
there——主语,is——系动词,a pen——表语
而“on the desk”——在句中担当什么成分,修饰哪个语
是不是做“地点状语”用于修饰全句的吗？我感觉它肯定不是修饰“表语”的

Answer 1

首先,there不是主语.主语是a pen.
there be 句型其实是倒装句
there is a pen on the desk.
=A pen is on the desk.
其次,on the desk 其实是表语来的.
所以,你的观点是有道理的.
