限制性定语从句(1)一、概述1.定语从句的概念情景导学Tan Yunxian(1461-1554) was a Chinese physician wh learned her skills frm her grandparents. 谭云仙(1461—1554)是一位中国医生,师从祖父母。 (2023全国乙)It’s a questin that Prfessr Crystal wuld ask her students.Crystal教授会问她的学生这个问 题。 (2022北京)She’s an artist whse wrk I really admire.她是一位艺术家,她的作品令我赞赏不已。There was a time when I had sme difficulties in my life.有一段时间我的生活中遇到了一些困难。
用法归纳(1)定语从句是在句中修饰、限制或补充说明一个名词(或代词)的从句。被定语从句修饰的 名词(或代词)叫先行词。(2)引导定语从句的词叫关系词。关系词分为关系代词(that、which、wh、whm、whse) 和关系副词(when、where、why)。2.定语从句的种类情景导学His sn wh/that is a dctr is my best friend.(限制性定语从句)他当医生的那个儿子是我最好 的朋友。His sn, wh is a dctr, is my best friend.(非限制性定语从句)他的儿子是一名医生,他是我最
好的朋友。用法归纳定语从句分为限制性定语从句和非限制性定语从句。(1)限制性定语从句它是先行词在意义上不可缺少的定语,如果去掉,主句的意思就不完整或失去意义。这种从 句与主句的关系十分密切,书写时通常不可用①　　    与主句隔开。(2)非限制性定语从句它只是对先行词作附加说明,如果去掉,主句的意思仍然清楚、完整。这种从句与主句的关 系不是很密切,书写时往往用逗号与主句隔开。非限制性定语从句通常不用that引导。
二、定语从句的关系代词的用法情景导学Li Fei is the girl (that/wh/whm) I usually g t schl with.李菲就是通常和我一起去上学的 那个女孩。(指人,作宾语)Li Fei is the girl with whm I usually g t schl.李菲就是通常和我一起去上学的那个女 孩。(指人,作宾语)The number f the peple wh/that cme t visit this city each year reaches ne millin.每年来 参观这座城市的人的数量达到一百万。(指人,作主语)This may be the suitcase that/which cntains imprtant materials.这也许是那个装有重要资料的 手提箱。(指物,作主语)
The farm (that/which) we visited last week is very big.我们上周参观的那个农场很大。(指物, 作宾语)I met a girl there whse hair came dwn t her waist.我在那儿遇见一个长发及腰的女孩。(指人,作定语)We?ll rebuild the huse whse rf was damaged in the earthquake.我们将重建那个屋顶在地 震中受损的房子。(指物,作定语)用法归纳定语从句的关系代词有三大作用:(1)引导作用:引导定语从句。(2)替代作用:在定语从句中替代②　　　    。注意关系代词whse在替代先行词的同时还带 个 “的”,它相当于名词所有格,所以它在定语从句中作定语。(3)成分作用:因为关系代词替代了先行词,所以它在定语从句中充当成分,具体见下表:
特别提醒关系代词作宾语时通常可以省略,但关系代词前面是介词时,关系代词不可以省略,且只能使 用which(指物)、whm(指人)。三、用that不用which的情况情景导学All that glitters is nt gld.闪闪发光的东西未必都是金子。There is little that I can d.几乎没有什么我能做的。This is the mst interesting stry that I have ever read.这是我看过的最有趣的故事。The first thing (that) we shuld d is wrk ut a plan.我们应该做的第一件事是制订一个计划。Which is the bike that yu lst?哪一辆是你丢的自行车?
I’ll never frget the peple and the events that impressed me.我永远不会忘记那些给我留下深 刻印象的人和事。用法归纳(1)先行词既有人又有物时,关系词用that。(2)先行词为 everything、smething、nthing、anything、all、nne、little、few、much等不 定代词时或被few、little、much、the nly、the very、all、every等修饰时,常用关系代词that 来引导定语从句。(3)先行词被序数词或形容词最高级修饰时,用关系代词that不用which。(4)主句是特殊疑问句且疑问词是which时,定语从句的关系代词用that。
四、用which/wh不用that的情况1.用which不用that的情况情景导学That which des nt defeat us makes us strnger.打不倒我们的东西会让我们更强大。用法归纳当先行词本身就是that时,关系代词用which。2.用wh不用that的情况情景导学I must help thse wh are badly in need f help.我必须帮助那些急需帮助的人。One wh has nthing t fear dares t tell the truth.无所畏惧的人敢于说实话。We welcme anyne wh has an interest in painting.我们欢迎任何对绘画感兴趣的人。
用法归纳先行词是指人的thse、ne,不定代词anyne,人称代词he等时,定语从句的关系代词常用wh不用that。五、定语从句中的主谓一致情景导学The by wh was reading a nvel in his wn rm didn’t knw the accident.那个在自己的房间 看小说的男孩不知道这起事故。Tmmy is the nly ne f the pupils that has failed the exam.汤米是那些学生中唯一考试没及 格的人。She is ne f the students wh sing well.她是唱歌唱得好的学生之一。
用法归纳(1)关系代词在定语从句中作主语时,从句的谓语动词在人称和数上应与前面的先行词保持 一致。(2)当“the nly ne f the+复数名词”后跟定语从句时,先行词是the nly ne,而不是复数名词,所以谓语动词用⑧　　    数。(3)当“ne f the+复数名词”后跟定语从句时,先行词是复数名词,谓语动词用⑨　　     数。
