定语从句that和which和who和whose和whom用法的区分

定语从句that和which和who和whose和whom用法的区分

which that 可以引导定语从句,并且都可以在定语从句中充当主语或宾语.
which指代的先行词只能是物,that指代的先行词既可以是物,也可以是人.
在下列三种情况下只能用which,不能用that：
1、紧跟在介词后面.如：
This is the very pen,with which I have written many articles.
2、which后面有插入语.如：
This is the gramma book which,as I have told you,will improve your English.
3、引导非限制性定语从句.如：
She has a house,which was built last year.
但在下列六种情况下只能用that：
1、先行词有形容词的最高级或序数词修饰时,必用that.如：
It is the first shop that lies at the foot of the mountain.
2、在不定代词,如：anything,nothing,the one,all,much,few,any,little等作先行词时,只用that.如：
All that haven't been done must be done at once.
3、先行词既有人,又有物时,只用that.如：
We finally saw the school and teachers that we haven't seen for nearly ten years.
4、在there be 句型中,只用that,不用which.如：
There is a ruler that is made of wood.
5、先行词有the only,the very修饰时,只用that.如：
Lucy is the only girl that comes from America.
6、 关系代词在从句中作表语并带有类比含义时,通常只用that,不用which.如：
He is no longer the star that he was.他不再是过去的那位明星了.
who只能指代人,在从句中作主语或宾语（但不能用在介词后面,介词后面只能用whom）.
I saw a man who is a teacher.我看见一个当老师的人.
whom也只能指代人,在从句中只能作宾语.
I saw a man pass by with whom was a lovely dog.我看见一个男人从我身边走过,跟它在一起的是一条可爱的狗.
whose在从句中只能作定语,修饰某个名词,这个名词可以是人,也可以是物.如：
I saw a house whose roof was broken.我看见一座屋顶已经坍塌了的房子.
I met a woman whose dress was very beautiful.我看见一个穿着很好看的裙子的妇女.
