Question

this the house ( )we uesd to sleep. A.Where B.which C.that D.when

A.Where B.which C.that D.when
讲解定语从句主语，宾语怎么区分啊？
比如：
I found a man( ) is stangding under that tree
为什么不用whom 用who?

Answer 1

this is the house (where)we uesd to sleep
=this is the house (in which)we uesd to sleep
句子还原：
we uesd to sleep in the house
house在动词后面，所以是宾语

I found a man(whom/who) is standing under that tree
还原：a man is standing under that tree
a man是宾语，所以用whom/who或者省略

若a man who is standing under that tree ........
那么man作主语，只能用who

Understand？

Answer 2

A 关键是看从句中的动词

whom是宾语，who是主语，看从句，把从句当成一个句子来填词

Answer 3

MAN是宾语从句的主语所以用主格who

Answer 4

应该是选 where吧the house是物是那里可以去睡
第二个选who whom的意思是...的人
这样句子就不对的。我看见一个老人站在树下。应该是这样的
