限制性定语从句(I)(which,that,wh,whm,whse)定语从句是用来充当句中定语的从句,它主要用于修饰句子中的名词、代词,其位置位于被修饰的名词、代词之后。在被修饰的名词、代词与定语从句之间往往有一个关系词将其前后两部分联系成一个整体,关系词可分为两种:关系代词和关系副词。常见的关系代词有:that,which,wh,whm和whse。一、关系代词的用法1.wh指人,在定语从句中做主语或宾语。There’s a man at the frnt dr wh wants t see yu.前门口有个人想见你。Thse wh want t g uting must be at the schl gate at 7 tmrrw mrning.想去郊游的人必须在明晨7点到大门口集合。
2.whm指人,在定语从句中做宾语,常可省略。Mr.Smith is the man (whm) yu talked abut n the bus.史密斯先生就是你们在公共汽车上谈论的那个人。The mnitr is just the student (whm) I want t see.班长正是我想要见的那个学生。注意:关系代词whm 在口语或非正式文体中常可用wh 来代替,也可省略。The man (whm/wh) yu met just nw is my brther.你刚才遇到的那个人是我哥哥。3.which指物,在定语从句中做主语或宾语,做宾语时常可省略。Basketball is a game which is liked by mst peple.篮球是大多数人都喜欢的运动。The dictinary (which/that) I bught last week is very useful.我上周买的字典很有用。
4.that指人时,相当于wh 或whm;指物时,相当于which。在定语从句中做主语或宾语,做宾语时常可省略。The number f peple that/wh cme t visit this city each year reaches ne millin.每年来参观这座城市的人数达一百万。The managers discussed the plan that/which will be carried ut the next year.经理们讨论了明年将会执行的计划。
5.whse通常指人,也可指物,在定语从句中做定语。whse 后必须有一名词。He has a friend whse father is a dctr.他有一个爸爸当医生的朋友。Children wh are nt active r whse diet is high in fat will gain weight quickly.不爱运动或者饮食热量偏高的孩子们会很快发胖。
二、限制性定语从句中只能用that引导定语从句的情况1.当先行词是everything,anything,nthing,all,nne,few,little,sme等不定代词时,或当先行词受every,any,all,sme,n,little,few,much等代词修饰时。Have yu taken dwn everything that Mr.Li said?李老师讲的你都记下来了吗?There seems t be nthing that is impssible t him in the wrld.对他来说似乎世界上没有什么不可能的事。All that can be dne has been dne.所有能做的都做好了。There is little that I can d fr yu.我不能为你干什么。He stayed in the library and lked up any infrmatin that they needed.他待在图书馆查找他们所需的资料。
2.当先行词被序数词修饰时。The first place that they visited in Lndn was Big Ben.在伦敦他们参观的第一个地方是大本钟。3.当先行词被形容词最高级修饰时。This is the best film that I have ever seen.这是我看过的最好的电影。4.当先行词被the very,the nly修饰时。This is the very dictinary that I want t buy.这正是我要买的词典。After the fire in his huse,the ld car is the nly thing that he wns.房子失火后,这辆旧车是他唯一拥有的东西。
5.当先行词前面有wh,which等疑问代词时。Wh is the man that is standing by the gate?站在门口的那个人是谁?Which is the T-shirt that fits me mst?哪件T恤衫最合我的身?6.当先行词为人与动物或人与物时。They talked abut the persns and things that they remembered at schl.他们谈论着他们所能记起的上学时的人和事。Lk at the man and his dnkey that are walking up the street.瞧瞧那个沿街走来的人和他的毛驴。
