Part Using language定语从句(3)【思维导图】.基本特征感悟【感悟用法】The man to whom you talked just now is my English teacher.He is adopting a new teaching method in which we are all interested.Tomorrow is the Teachers Day on which we are going to give him a gift in order to thank him.【自我总结】上文中黑体部分引导的是定语从句，它们均为介词关系代词。.主要用法精讲一、“介词关系代词”结构中的关系代词“介词关系代词”是一种普遍使用的结构。“介词关系代词”结构中的关系代词只可用whom或which，不可用that。Do you remember the day on which (when) you joined our club?还记得你加入我们俱乐部的那一天吗？In the dark street, there wasnt a single person to whom she could turn for help.在漆黑的大街上没有一个人她能够求助。二、“介词关系代词”结构中介词的确定介词的选择可以总结为：“一先、二动、三意义、四特殊”。1.一先，即先看先行词，从先行词入手。介词往往和先行词构成固定搭配。(比如时间常和on, in, by搭配；地点常用on，in，at；原因用for；方式用in，by，with等)This is the house in which (where) the inventor lived.这就是那位发明家住过的房子。2.二动，即看从句中的谓语动词结构。根据从句中谓语动词的搭配选择合适的介词。He is the person of whom everyone has heard.(hear of 听说)他是那位所有人都听说过的人。3.三意义：通过判断主句表达的全部意义来确定合适的介词。He was educated at a local high school，after which he went on to Beijing University.他在当地的一所高中上学，之后他继续在北京大学学习。4.四特殊：介词of 常用于“表示部分的词语of关系代词结构”。表示部分的词语常见的有：不定代词all，both，none，neither，either，some，any，数词(含基数词，序数词，分数和百分数)；数词名词；the最高级/比较级，以及表示数目或数量的词语many，most，few，several，enough, half, a quarter。There are sixty students in our class，twenty of whom are girls.我们班有六十名学生，其中二十名是女生。The factory produces half a million pairs of shoes every year, 80% of which are sold abroad.这家工厂每年生产50万双鞋子，其中的80%销往国外。There are two rooms，the smaller of which is my study room.有两个房间，较小的那个是我的书房。 “介词关系代词”引导的定语从句中可用的关系代词有哪些？此结构中可以把关系代词换成关系副词吗？指人时，用whom；指物时，用which。该结构中不能把关系代词换成关系副词，因为介词后要跟关系代词。即学即练用“介词关系代词”填空1.There are some occasions on_which one must give in.2.Can you tell me the reason for_which you didnt come to her birthday party?3.Water is a thing without_which man cant live.4.The old woman has two sons, both of_whom are doctors.名师提醒像listen to, look at, depend on, pay attention to, take care of等固定动词短语，在定语从句中一般不宜将介词与动词分开。This is the person whom/who/that you are looking for.这就是你在找的那个人。.用“介词关系代词”填空1.Wind power is an ancient source of energy to_which we may return in the near future.2.The newly-built caf，the walls of_which are painted light green, is really a peaceful place for us, especially after hard work.3.This is the teacher from_whom Ive learnt a lot.4.Gun control is a subject about_which Americans have argued for a long time.5.The policeman with/about_whom Mr Henry is talking is a friend of mine.6.He built a telescope through_which he could study the stars.7.My father is the first person to_whom I will turn for help when I meet difficulties.8.Is she the girl from_whom you borrowed the dress yesterday evening?9.I will never forget the day on_which I was admitted to a famous university.10.Would you be kind enough to help the boy for_whom Chinese is really hard to learn?.用“介词关系代词”补全句子1.Students should take an active part in the communityactivities from_which_they_can_gain_social_experience.学生们应该积极参加那些能够让他们获得社会经验的社区活动。2.This is the policeman by_whom_my_son_was_saved.这正是救了我儿子的警察。3.This is the house in_which_I_lived_two_years_ago.这是我两年前住过的房子。4.In my first chemistry class I knew the fact that this kind of colorless gas without_which_we_cant_live is called oxygen.在我的第一堂化学课上，我知道了这个事实：这种无色气体被称作氧气，没有它我们无法生存。5.History is the subject in our school in_which_every_student_is_interested.历史是我们学校每个学生都很感兴趣的课程。.语法填空I was twelve years old when I learnt to ride a bike.The bike was a birthday present from my uncle.You can imagine how 1._ (excite) I was when I saw the bike, and I begged my uncle to teach me how 2._ (ride) it right away.However, before I got on the bike, I felt 3._ (extreme) nervous and I was afraid that I would fall off and hurt 4._(I).My uncle held onto the seat and helped me to get 5._ the bike.While I was riding, he was running along beside me, holding the seat so I would not fall over.I was so 6._ (gratitude) to him for his help.As I was practicing, I became more and more confident.Then, I heard my uncle shouting, “You are riding it by yourself now！” I was scared.I was really riding by myself, but 7._ if I fell off?
