1、语法复习三：名词性从句名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。（-）引导名词性从句的连接词1、连接代词：who,whose,whom,what,whicho有词义，在从句中担任成分，如主语、表语、宾语、或语等2、连接副词：when,where,why,how。有词义，在从句中担任成分，作状语。3、连接词：that,whether,if,asif。that无词义,在从句中不担任成分，有时可省略；if（whether）,asif虽有词义，但在从句中不担任成分。注意:连接代词与连接副词在句中不再是疑问句，因而从句中谓
2、语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether和if（是否），asif（好象）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whetherif和asif都用不上时，才用that作连接词（that本身无任何含（二）主语从句1、主语从句在复合句作主语。e.g.Whowillgoisnotimportant.2、用it作形式主语，主语从句放在句末。e.g.Itdoesntmattersomuchwhetheryouwillcomeornot.3、that引导主语从句时，不能省略。e.g.Thathesuddenlyfellilllastweekma
3、deussurprised.（三）表语从句1、表语从句在复合句中作表语，位于系动词之后。e.g.Thequestionwaswhocouldgothere.2、引导表语从句的连接词that有时可省去。e.g.Myideais（that）wecangetmorecomradestohelpinthework.（四）宾语从句1、宾语从句在复合句中作宾语。引导宾语从句的连词that般可省略e.g.Ihope(that)everythingisallright.2、介词之后的宾语从句，不可用which或if连接，要分另U用what或whetheroe.g.Kminterestedinwhetheryo
4、uvefinishedthework.Pminterestedinwhatyouvesaid.3、whether与if都可以引导宾语从句，常可互换。但下面情况不能互换。 宾语从句是否定句时，只用if,不用whether。e.g?Iwonderifitdoesntrain. 用if会引起误解，就要用whetheroe.g.Pleaseletmeknowwheth皀ryouwanttogo.(此句如果把whether改成if,容易当成条件句理解) 宾语从句中的whether与ornot直接连用，就不能换成if；不直接连用，可换。e.g.Idontknowwhetherornotthereporti
5、strue.Idontknowwhether/ifthereportistrueornot. 介词后的宾语从句要用whether引导。whether可与不定式连用。whether也可引导主语从句、表语从句、同位语从句，还可引导让步状语从句，以上均不能换成ifo但引导条件从句时，只能用if,而不能用wh皀theree.g.Itdependsonwhetherwehaveenoughtime.Theydontknowwhethertogothere.Pleasecometoseemeifyouhavetime?(五) 同位语从句同位语从句在句中作某一名词的同位语，一般位于该名词(如:news,fa
