人教版选修八Unit1AlandofdiversityPeriod3Grammar名词性从句

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，名词从句又可分别称为主语从句(SubjectClause)、宾语从句(ObjectClause)、表语从句(PredicativeClause)和同位语从句(AppositiveClauseWhowillwinthematchisstillunknown.Iwanttoknowwhathehastoldyou.Thefactisthatwehavelostthegame.Thenewsthatwewonthegameisexciting.主语从句宾语从句表语从句同位语从句

SubjectClause(主语从句)

ObjectClause(宾语从句)Nounclause

PredicativeClause(表语从句)

引导主语从句的连词是不能省略的。

ThattheearthisroundistrueThat-从句作主语通常用it作先行词，而将that-从句置于句末，例如：

Itistruethattheearthisround.

It'sapitythatyoushouldhavetoleave.你非走不可真是件憾事。Attention用it作形式主语的that-从句有以下四种不同的搭配关系：It+be+形容词+that-从句

Itisnecessarythat…有必要……

Itisimportantthat…重要的是……

Itisobviousthat…很明显……b.It+be+-ed分词+that-从句

Itisbelievedthat…人们相信……

Itisknowntoallthat…从所周知……

Ithasbeendecidedthat…已决定……

what引导名词性从句时在从句中充当句子成分,如主语,宾语,表语,表示…的.而that那么不然,它在句子中只起连接作用,没有意义.(1)Whatyousaidyesterdayisright.(2)Thattheearthgoesaroundthesuniswell-knowntoeverybody.3.____leavestheroomlastoughttoturnoffthelights.A.Anyone

宾语从句一个句子在复合句中充当宾语就叫宾语从句。e.g.DoyouknowwhereheisI’mglad(that)youhavepassedtheexam.Idon’tknowwhether(if)youarewillingtohelpme.I’msorryforwhatIhavesaid.我为我说的话表示歉意。特别提示1.由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。3.用who，whom,which,whose,what,when,where,why,how,whoever,whatever,whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。DoyouknowhowoldheisIwanttoknowwhathehastoldyou.我想知道他告诉了你什么。

Shealwaysthinksofhowshecanworkwell.她总是在想怎样能把工作做好。

Shewillgivewhoeverneedshelpawarmsupport.凡需要帮助的人，她都会给予热情的支持。4.think,believe,imagine,suppose等动词引起的否认性宾语从句中，要把上述主句中的动词变为否认式。即将从句中的否认形式移到主句中。例如：

Wedon’tthinkyouarehere.我们认为你不在这。

Idon’tbelievehewilldoso.我相信他不会这样做。

特别提醒1.表语从句中的时态不受主句的限制.2.
