Question

2 He lives in a house which windows face south.
3 There are many young men that are against the plan.
4 You should hand in all which you have.
5 The girl who often help mo with my English is him.
6 He has three sons,two of them are music lovers.
5句中mo为me，him为her
3、4句什么理由啊？有依据吗？
6句，当两个单句理解可以吗？

Answer 1

1that改成which
2which改成where 从句结构完整不需要用which，where在这是地点状语
3that改成who 主语指的是人，who在从句中代人
4which改成what 从句缺少宾语，you have what
5who改成whom 在句中作宾语，是引导词，引导定语从句
6them 改成whom 这里是定语从句，主语是人用who或whom，但跟在介词后只能用whom

Answer 2

1没错？要么certainly放这里不行，不确定
2which改whose，定语从句，从its变换来
3that改who，there are 句型里that不能代替who做定语从句
4which改that，作为定语从句，all后面不能加which
5这个女孩是him？改一个。另外mo是me？
6them改whom，逗号后面只能是定语从句

Answer 3

1句中that去掉
2句中的which改成of which或whose

Answer 4

1、that--who 先行词是one,指人用who
2、which--where 先行词在从句中作地点状语，关系副词当然用where
3、that--who 先行词是men指人用who
4、which--that 先行词是all，不能用which引导，要用that
5、him--she 主语是女孩
6、them--whom 逗号隔开，非限制性定语从句，指人，引导词不能用them，要用whom

Answer 5

1、that--who 先行词是one, ones,等只用who，不用that。当先行词指人时，下列情况宜用who 不用that
先行词是one, ones, anyone
Anyone who breaks the law should be punished.
先行词为those, 且指人
Those who want to see the film sign up here.
当先行词有较长的后置定语修饰且定语为物
I met a foreign student from Beijing University who could ask me questions in Chinese.

2、which--whose 先行词在从句中作定语，关系词当然用whose,或者改为
He lives in a house which faces south.
3、that--who 先行词是men指人,在there be 开头的句子中
There are many young men who are against the plan.
4、which--that 在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。all that 相当于what.You should hand in what you have.
5、help--helps主语是女孩单数The girl who often helps me with my English is her
6、them--whom 限制性定语从句，指人，引导词不能用them，要用whom,of whom 相当于whose
