定语从句 耶鲁YY语音

You are the students. The students are listening to the YY.. You are the students listening to the YY. who are listening to the YY. 一、定义：在英语句子中，用于限定名词或代词的句子，叫做定语从句。 二、构成：先行词+关系词+定语从句（一般情况下，三者紧挨着，顺序不可变） 注：1.被定语从句修饰的词叫做先行词。 2.关系词指代先行词，两者为同一事物。

三、关系词 关系代词： who，that ，whom，whose which, as 关系副词： when where why 注意：没有what how

关系词的选择 当从句缺少成分(主、宾、表)时，用关系代词。 当从句不缺少成分时，用关系副词. 关系词做宾语成分时可以省略 判断却不缺成分以“五大基本句型”为标准。

(1)Is this the factory __ he worked last year (1)Is this the factory __ he worked last year? (2)I like the place __ I visited three years ago. (3)He is the star __ we love. A.when B.where C.which D.whom E.that

定从的位置： 从______后开始找，如果有一个谓语动词，______后都是从句。 如果有两个谓语动词，______与第二个谓语动词之间的为从句。 ⑴The girl ___ my father is talking to is my girl friend. ⑵The work ___ has just been finished is very important. ⑶I’ll never forget the day ___ we first met each other. A. which B. whom C. when D. who E. that F. where 注：若____前有名词，通常考定语从句。

whose的使用：1. 从句不缺成分 2. 先行词与从句主语构成从属关系 3 whose的使用：1.从句不缺成分 2.先行词与从句主语构成从属关系 3.从句的主语前没有the 例：(1)This is the scientist _C_ achievements(成就)are well known. A.who B.whom C.whose D.of whom

注：whose + n. = of which/whom + the + n. = the + n 注：whose + n.= of which/whom + the + n.= the + n.+ of which/whom 例：This is the house, the window of which was broken last night. This is the house whose window broken last night.

关系代词which与that的区别 只用that不用which的情况： 1.当先行词是 something, everything, anything, nothing, some, all, a little, little, a few, few等不定代词或被这些词修饰时，用that,不用which。 2.当先行词前有形容词最高级、序数词或有the only,the very(正好，正是),the last,just修饰时，用that,不用which。

3. 当先行词既有人又有物时，用that,不用which。 4. 当主句主语是who或which引导的疑问句时，用that,不用which 3.当先行词既有人又有物时，用that,不用which。 4.当主句主语是who或which引导的疑问句时，用that,不用which. (1)Do you have anything __ you want to say. (2)This is the best movie __ I’v ever seen.

(3)Do you know the things and persons ----- they are talking about (3)Do you know the things and persons ----- they are talking about? (4)Who is the boy __ won the gold medal(金牌)?

只用which不用that的情况： 1.当关系代词前有介词时，用which,不用that 例：This is a house in which Lu Xun once lived. 注：此时，介词+关系代词 相当于 关系副词，且介词要与先行词或从句动词构成搭配。 如上句：This is a house where Lu Xun once lived

This is the factory ______ he worked last year. A. which B. in that C This is the factory ______ he worked last year. A.which B.in that C.in which D.of which Tom is the boy ______ he talked yesterday. A.whom B.with whom C.of which D.of who

2.在非限制性定语从句中，用which, 不用that。 定语从句的分类及其它的高频考点我们（下次继续）

3.在非限定性定语从句中，只是不用that,其他关系词可以用： 2.在非限制性定语从句中，用which, 不用that 定语从句的分类： 限制性定语从句： This is the book that/which I want to read. 非限制性定语从句： This is the book , which I want to read. 注： 1.限制性定语从句中无“，”连接 非限制性定语从句中有“，” 连接 2.在限制性定语从句中，当关系词作宾语时，可以省略。 例：This is the book (that/which) I want to read. This is the book , which I want to read. 3.在非限定性定语从句中，只是不用that,其他关系词可以用：

(1)She has fallen in love with Jack,______ I find hard to imagine (1)She has fallen in love with Jack,______ I find hard to imagine.(2009) A who B that C whom D which (2)Mr.Zhuang,______ came to see me yesterday, is an old friend of my father’s. (2006) A which B that C who D whom

当先行词为the way(方式、方法)时，且当从句不缺成分时，关系词有三种情况：that/in which/不填 I don’t like ____ you speak to her.(2013) A.the way B.the way in that C.the way which D.the way of which

关系代词as、which 的区别 1，当先行词由such ，as，the same修饰时，从句缺宾语时，只能用as The result is not the same as they had expected, 2，在非限制性定语从句中，as和which 都可以代表前面一整句话的内容。as 引导的从句可位于主句前，主句中，主句后。 which 引导的从句只能位于主句后。

此外，as 用于以下固定搭配： As we know(正如我们所知) as is often the case(像通常那样) As has been said before(如上所述) as is reported(正如报道的那样) As is well known(众所周知) as was expected(正如预料的那样) Eg：As we know,smoking is harmful to one’s health

其他要点 1.One of + 复数名词（v用复数） The only one of + 复数名词（v用单数） 例：He is one of the boys who are handsome. He is the only one of the boys who is handsome.

2.数词/代词 + of which/whom 表示先行词的数量。 此类词有：all，none，both，neither，either，some，most… (1)She has ten friends,______ is a girl. A.none of which B.none of whom C.neither of which D.either of which (2)I have two pens,______ writes well. A.none of them B.none of which C.neither of which D.either of them

3，先行词为：Point(境界),case(事例),position(境地),stage(阶段),condition(条件),circumstance(境况)，关系词用where。 They have reached the point ______ they have to say goodbay to each other. A.that B.which C.where D.when

4，插入语I think,I believe,I guess,I suppose,I imagine,in my opinion 通常放在关系词与从句之间。做题时，不考虑插入语。 例：He made another wonderful discovery,______ of great importance to science. A. which I think is B. which I think it is C.which I think it D.I think is (2012)
