1、 语法专项提升 定语从句 关系代词that与which的用法区别 (1)关系代词指代物,而引导词只用which不用that的情况: 关系代词指物,作介词宾语的时候: This is the question about which they have had so much discussion in the past few weeks. 这是他们在过去几周讨论了多次的问题。 关系代词指前面的整个句子,引导非限制性定语从句时: He failed in the exam,which made his father angry. 他考试不及格,这使他父亲很生气。 (2)that和which都指
2、物时,在下列四种情况下只能用that而不能用which:当先行词是all,everything,something,nothing,anything,much,little,few等不定代词时。 There was little that I could do for you.我不能为你做什么。 That is all that I want to say.那就是我想要说的。当先行词被序数词和形容词最高级修饰时。 The first place that they visited in Guilin was Elephant Trunk Hill.在桂林他们所参观的第一个地方是象鼻山。 Thi

4、谈论的人和事吗?当主句的主语是疑问词who或which时。Which is the bike that you lost?哪一辆是你丢失的自行车?Who is the boy that won the gold medal?获金牌的小男孩是谁? 介词关系代词 (1)介词关系代词中介词的宾语只能是which或whom。 The gentleman about whom you told me yesterday proved to be a thief.你昨天告诉我的那位绅士证实是小偷。 In the dark street,there wasnt single person to whom s
5、he could turn for help.在漆黑的大街上没有一个人能为她提供帮助。 (2)当复合介词短语which引导定语从句时,这种定语从句常与先行词用逗号隔开,从句用倒装语序。 He lived in a big house,in front of which stood a big tall tree. 他住在一所大房子里,房前有一棵大树。 (3)介词which/who不定式结构。 The poor man has no house in which to live. 那个可怜的人没有房子住。(4)ofwhich/whom表示所属关系。(表所属关系也可用whose)Recently
6、I bought an ancient vase,the price of which (whose price) was very reasonable. 最近我买了个古代的花瓶,它的价钱很合理。 关系代词as引导的定语从句 关系代词as既可以引导限制性定语从句,也可以引导非限制性定语从句,as在从句中作主语、宾语或表语。 引导限制性定语从句常用于下列句式: 其中关系代词as在从句中担当主语、宾语或表语。We have found such materials as are used in their factory. 我们已经找到了像他们工厂里用的那种材料。(as作主语)These hou

9、 was more than we could expect.(2)当非限制性定语从句放在主句前面时,只能用as。As is known to everybody,the moon travels round the earth once every month.

10、 is known to everybody is that the moon travels round the earth once every month. 后两句属名词性从句范畴。(3)as意为“正如”,后面的谓语动词多是see,know,expect,say,mention,report,announce等;which意为“这一点”。As is known to all,Edison invented the telephone.

13、2)the only one of复数名词关系代词单数动词He is the only one of the students who passes the exam. 他是唯一通过考试的学生。 (3)其他情况I,who am your teacher,will try my best to help you. 我,你的老师,将尽力帮你。Have you heard of the persons and things that are being talked about?你听说过正在被谈论的这些人和事吗?1(2009年福建卷)Its helpful to put children in a
14、situation_they can see themselves differently.Athat BwhenCwhich Dwhere【解析】句意为:把孩子放在一个能使他们从另外一个角度认识自己的环境中对他们有益。本题考查定语从句,先行词是situation,代入定语从句后为:They can see themselves differently in_the_situation.由此可见,先行词在定语从句中作状语,故用关系副词;而when表“时间”,不合本题要求,只有where符合本题要求。【答案】D2(2009年山东卷)Whenever I met her,_was fairly o
