定语从句与名词性从句的区别

定语从句与名词性从句的区别湖南科技大学李婵区别一.•名词性从句中的主语从句、表语从句和宾语从句没有先行词·同位语从句有先行词词性但在从句中不做成分hope,answer,fact,belief,News,idea,information,order,conclusion,suggestion,plan,Truth,thought,doubt,promise,feeling等名词例句：（1）Thisistheboywhowearelookingforyesterday.定语从句（2）Thenewsthattheytoldmeexcitedme.同位语从句区别二.•在句子中起名词作用的句子叫名词从句(NounClauses）。名词从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能。·定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，定语从句分为限定性和非限定性从句两种。（1）HewhodoesnotreachtheGreatWallisnotatrueman.定语从句（2）Irememberwhatyousaid.名词性从句区别三.•定语从句和名词性从句的主要区别就在what、that、how、whether、if这几个词中。定语从句中不会用到what、how、whether、if这几个词。•并且that虽然在定语从句中作成分,但在名词性从句中却不作成分只起连接作用。练习题1).Ihatepeople_______talkmuchbutdolittle.A.whoseB.whomC.whichD.who2).Hejustdoes_______hepleasesandneverthinksaboutanyoneelse.A.thatB.whatC.whichD.how3).Itshockedmetosee________myneighborstreatedtheirchildren.A.whyB.whetherC.howD.since4).AtthattimeIhadnoidea________Icouldhandittohimwithoutbeingseen.A.ifB.howC.whichD.thathow5).Shetookitforgranted________I'dbebackhomeanhourago.A.thatB.whetherC.ifD.when6).Canyoupointout________tworadiosarethebestA.whichB.whatC.thatD.whetherTHANKS
