非限制性定语从句

修饰对象

译法上

关系副词

修饰名词或代词除修饰名词或代词外还可以修饰整个主句译成先行词的定语：“……的”通常译成主句的并列句。When,where,whywhen,where,forwhich“非限定”使用须知1.从句中所有的关系词都不可省略2.从句通常不能用that引导3.在“非限定”中,指人的关系代词作宾语时,只能用宾格whom,不能用who替换,也不能省略。4.从句不能用why引导,要用forwhich代替why5.从句置于句首时,不能用which引导;而要用关系代词as

引导(as可放主句前,也可放主句后)要点归纳非限制性定语从句的易错点总结三____weallknow,Chinaisacountrywithalargepopulation.As这是一个定语从句提前的句子，由as引导;理解为“正如…，如同…”试翻译：正如所报道的，医生们已经找到了治疗这种病的方法。Asisreported,doctorshavefoundthewayofcuringthedisease.

1)Ihaveasisterwhoworksinahospital.我有一位在医院工作的姐姐。（不只一位姐姐）2)Ihaveasister,whoworksinahospital.我有一位姐姐，她在医院工作。（只有一位姐姐）注意1：有时同一个限制性从句变为非限制性从句会改变全句的意思。Hisfather,whoworksinBeijing,camebackyesterday.Shanghai,whichisinEastChina,isdevelopingrapidly.注意2:当先行词是地名人名、世界上独一无二的事物或家庭唯一成员时，通常只用非限制性定语从句。

as和which可指代整个主句

(=andthis/andthat)

as可放在句中或句首,which只放在句中

_____weknow,smokingisharmfultoone'shealth.Thesunheatstheearth,______isveryimportanttous.Aswhich注意3:as/which引导非限定性定语从句的区别

关系代词as在定语从句中指代整件事，充当句中的主语或者宾语，它经常和thesame,such,as一起搭配使用，共同构成一个固定词组。Asweallknow,heisafamousscientist.Asisexpected,heisadiligentboy.Shehasthesamebookasyouhave.as引导非限制性从句，常意为“正如”。可出现在句首、句中、句末。常见结构有：asisknowntoallasisoftenthecaseasmight/couldbeexpected

ashasbeensaidbeforeashasbeenmentionedaboveashasbeenpointedoutascanbeimaginedascanbeseen(fromthesefigures)asoftenhappens

aswillbeshown这是常有的事正如人们所预料的正如上面所提到的正如前面所说的正如所指出的正如…所示Theearthisround.____isknowntoall.Theearthisround,_________isknowntoall.____isknowntoall,theearthisround.____isknowntoall
