高考英语语法备考精讲与练习名词性从句　　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。　　1、连接代词：who，whose，whom，what，which.有词义，在从句中担任成分，如主语、表语、宾语、或定语等。　　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，as无词义，在从句中不担任成分，有时可省略；if，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，asif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，whether、if和asif都用不上时，才用that作连接词。　　1、主语从句在复合句作主语。　　Whowillgoisnotimportant.　　2、用it作形式主语，主语从句放在句末。　　Itdoesn‘tmattersomuchwhetheryouwillcomeor not.　　3、that引导主语从句时，不能省略。　　Thathesuddenlyfellilllastweekmadeussurprised.　　1、表语从句在复合句中作表语，位于系动词之后。　　Thequestionwaswhocouldgothere.　　2、引导表语从句的连接词that有时可省去。　　Myideaiswecangetmorecomradestohelpinthework.　　1、宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。　　Ihopeeverythingisallright.　　2、介词之后的宾语从句，不可用which或if连接，要分别用what或whether.　　I‘minterestedinwhetheryou’vefinishedthework.。　　I‘minterestedinwhatyou’vesaid.　　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。　　①宾语从句是否定句时，只用if，不用whether.　　Iwonderifitdoesn‘train.　　②用if会引起误解，就要用whether.　　Pleaseletmeknowwhetheryouwanttogo.　　③宾语从句中的whether与or not直接连用，就不能换成if；不直接连用，可换。　　Idon‘tknowwhetherornotthereportistrue.　　Idon‘tknowwhether/ifthereportistrueornot.　　④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if.但引导条件从句时，只能用if，而不能用whether.　　Itdependsonwhetherwehaveenoughtime.　　Theydon‘tknowwhethertogothere.　　Pleasecometoseemeifyouhavetime.　　同位语从句在句中作某一名词的同位语，一般位于该名词之后，说明该名词的具体内容。　　Ihavenoideawhenhewillbeback.　　Thefactthathehadnotsaidanythingsurprisedeverybody.　　1.Chinaisnolongerwhatitusedtobe.　　2.Thetruththattheearthturnaroundthesunisknowntoall.　　3.Itwassnowingwhenhearrivedatthestation.　　4.Howhepersuadedthemanagertochangetheplanisinterestingtousall.　　5.Thenewsthattheyhadwonthegamesoonspreadoverthewhole
