定语 从句由关系词（关系代词、关系副词）引导，关系代词、关系副词位于定语从句句首。
在以下六种情况下多用who ：
①关系代词在从句中做主语
A friend who helps you in time of need is a real friend .
②先行词为those ,people 时
Those who were either fools or unfit for their offices could not see the cloth .
③先行词为all,anyone ,ones ,one 指人时
One who doesn’t work hard will never succeed in his work .
④在There be句型中
There is a stranger who wants to see you .
⑤在被分隔的定语从句中
A new teacher will come tomorrow who will teach you German .
⑥在有两个定语从句的句子中,其一用who,其二用that,但若先行词后接两个以上的并列定语从句时,后一个必须重复前一个关系代词.
The student who was praised at the meeting is the monitor that is very modest and studies very hard .
There is a teacher who is always ready to help others and who enjoys what he does .
这是我在高中的时候做的笔记,希望对你有用.
定语从句中whose的用法
一、whose为who的所有格，作“某(些)人的……”解，它所指代的先行词必须是人，其引导的定语从句修饰它的先行词，同时它本身在从句中作定语。
This is the little girl whose parents were killed in thegreat earthquake.这就是在那次大地震中失去双亲的那个小姑娘。
Mr Liu wants to talk to the students whose homework hasn't been handed in.刘老师要跟那些没交家庭作业的'学生谈话。
二、whose也可作which的所有格，作“某(些)物的……”解，它所指代的先行词必须是物，其语法的功能同上。
The company whose name was Notco was in Australia.那个名叫诺特可的公司设在澳大利亚。
We live in a house whose windows open to the south.我们居住在一所窗户朝南开的房子里。
三、whose可修饰定语从句中的主语、宾语、介词宾语等不同成分。
Mr King，whose legs were badly hurt，was quickly taken to hospital.金先生的腿受了重伤，很快就被送往医院。(whose修饰定语从句中的主语legs)
We shall have to make a decision about Ms King，whose story I've just told you.关于金女士的情况，我刚才已经告诉你们了，我们得对她的事情作出决定。(whose修饰定语从句中的宾语 story)
四、whose既可引导限制性定语从句，亦可引导非限制性定语从句。
The boss in whose department Mr King worked called at the hospital.金先生工作单位的老板到医院来探视。(限制性定语从句)
The boss of the company，whose name was Mr Little，told the story.公司的老板叫利特尔，他讲述了这个故事。(非限制性定语从句)
五、由于whose具有兼作who和 which的所有格的双重功能，故在指人时可用of whom代替whose，指物时可用of which代替whose。
This kind of book is for children whose native language(=the native language of whom)is Chinese.这种书是给母语是汉语的儿童看的。
Mr Brown has written a novel whose name(=the name of which)I've completely forgotten.布朗先生写了部小说，其书名我完全忘了。
I live in a room whose window(=the window of which)opens to the south. 我住在一间窗户朝南开的屋子里。
六、按英语习惯用法，下列情况中的whose和of whom或of which切不可混用：
1.凡是of whom或of which同数词或代词(如some，many，little等)连用表示部分与整体关系时，通常不可用 whose。
There are 45 students in our class，35of whom are League members.我们班有45名学生，其中35名是团员。
Mr White wrote many articles，some of which were translated into Chinese.怀特先生写了不少文章，其中一些译成了中文。
2.凡是of whom或of which修饰定语从句中的主语，是表示同位关系的代词both，all等时，切不可用whose。
I have two sons，both of whom serve in the army.我有两个儿子，都在部队服役。
