定语从句口诀
定语从句口诀定语从句口诀定语从句口诀：which指物who指人，whom、which介后陈。
that/only序all最，不定代词物与人。
that不用有逗号，介词提前更无份。
介宾不省动宾省，须做成分从句真。
定语从句口诀解释：“which指物who指人”，就是在引导定语从句时，如果先行词（被定语从句所修饰的那个名词）是物或者事情，就用which来引导(当然用that也行)，而如果先行词是人，就用who来引导(当然用that 也行)。
如：This is the bookwhichmy father bought last year.这就是我爸爸去年买的那本书。
which指物，即前面的the book,当然，that也行。
I still remember the boywhooften helps the old man.我还记得那个经常帮助那位老人的男孩。
who指前面的先行词the boy，当然，用that也行。
“whom、which介后陈”，就是当引导词做定语从句中介词的宾语、并且介词又提到了引导词的前面时，就只能用whom或which 来引导了。
如：The bookwhich/thatwe talkedaboutis new.我们谈论的那本书是新书。
在这个句子中，which或that指代的'是前面的the book,又同时作介词about的宾语，在介词about没有提前的情况下，which或that作从句中介词about的宾语是可以的。
The bookabout whichwe talked is new.我们谈论的那本书是新书。
此句中的介词about被提到了引导词which的前面，这时规定不可以再用that引导了，即“介词提前更无份”。
We all like the teacherwho/whom/thatwe learn a lotfrom.我们都喜欢我们从那里学到了很多知识的那名老师。

who的定语从句
who的定语从句who的定语从句导语：以下是店铺精心为大家整理的有关who的定语从句的分析，希望对大家有所帮助，欢迎阅读。
是定语从句被修饰的词叫先行词。
定语从句不同于单词作定语的情况，它通常只能放在被修饰的词（即先行词）之后。
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。
一、who引导的定语从句的先行词是表示人的名词或代词。
如：The studentwhois answering the question is John. 正在回答问题的那个学生是约翰。
Anybodywhobreaks the laws will be punished. 任何违反法律的人都将受到惩罚。
二、who是主格，在定语从句中作主语，此时不能省略。
如：The personwhowas here yesterday is a musician. 昨天来这儿的那个人是位音乐家。
但在非正式中，who亦可作宾语，且可以省略。
如：The man（who）I saw just now is Mr Li. 我刚才见到的那个人是李先生。
三、在定语从句中，who在人称、数上和其前面的先行词保持一致。
如：Do you know the boywhois standing over there? 你认识站在那边的那个男孩吗？四、若先行词中既有人又有物，关系代词用that而不用who。
如：He watched the children and boxes that filled the car. 他看见了塞满汽车的孩子和箱子。
五、若先行词前面有形容词最高级、序数词修饰，关系代词用that而不用who。
如：Yao Ming is the best basketball player that I know. 姚明是我知道的最好的篮球运动员。
Tom is the first boy that left the room. 汤姆是第一个离开这个房间的男孩。

Passage 2
Friendship is a very difficult thing. It is hard to handle. It creates many different problems. In fact I would say that friendship is as hard to handle as love is, or even marriage. Of course I am not talking about easy-come-easy-go friendship. I’m talking about friends who care deeply about each other, who support each other, who make life worth living. I’m talking about friends who you can share almost everything with. Useful Expressions:
1.He is the best grammar teacher who I have ever seen.
2.Anger is a thief who steals away the nice moments.
3. A rich person is not one who has the most, but is one who needs the
least.
4.The world is a book, and those who do not travel read only one page.
5.He who is not handsome at twenty, nor strong at thirty, nor rich at
forty, nor wise at fifty, will never be handsome, strong, rich or wise. Example:
I don’t like people who say one thing but do something else.
I don’t like people__________________________________.
I like people______________________________________.
I don’t like teachers________________________________.
A good friend is a person_____________________________.。
