连接词that和what的选用that和what都可引导所有的名词性从句。但是，______除起连接作用外，还在名词性从句中充当成分，可作从句的_______、_____、_____、或______。而_____在名词性从句中不充当任何成分，只起_______作用。what表示泛指的事物,常译为"什么"或"所……的事物"，在含义上等于“名词+that”what主语宾语表语that连接总结归纳：定语1.他犯了那样一个错误真是遗憾。___________________________isapity.2.他来不来不重要。________________________doesn’t

考点2：it作形式主语,形式宾语

it作形式主语it作形式主语，主语从句后移有时为了使句子结构平衡，避免“头重脚轻”，常用it作形式主语，而把主语从句，即真正的主语，放在后面。主语从句与形式主语it基本句型结构常用词语Itis＋名词＋that从句常用的名词有afact，ashame，apity，nowonder等。Itis＋形容词＋that从句常用的形容词有necessary，strange，important，possible等。当形容词为important，necessary等时，主语从句的谓语用“(should＋)动词原形”。Itis＋过去分词＋that从句常用的过去分词有said，reported，decided，believed，suggested，ordered等。过去分词为suggested，ordered等表“建议，命令”的词时，主语从句的谓语用“(should＋)动词原形”。It＋动词(短语)＋that从句常用的动词(短语)有seem，happen，turnout，occurto等。Itisapitythatshehasmadesuchamistake.她犯了这样一个错误，真是遗憾。Itisveryimportantthatastudent(should)learnEnglishwell.学生学好英语很重要。动词find，consider，think，feel，believe，make等后有宾语补足语时，常用it作形式宾语，而将真正的宾语that从句后置。IhavemadeitclearthatIwillnotacceptthisjob.我已表明我不会接受这份工作的。

it作形式宾语考点3同位语从句和定语从句的区别1.Thesuggestionthatheshouldnotgothereisofgreatvalue.2.Thesuggestionthathemadeisofgreatvalue.3.Thefactthathewonthefirstplacecan’tbedenied.4.Thefactthathementioned

excitedme.同位语从句同位语从句定语从句定语从句

同位语从句一般跟在名词fact,news,promise,truth,belief,thought,idea,answer,information,knowledge,doubt,hope,law,opinion,plan,suggestion，message，chance,conclusion,decision,后面,

用以说明或解释前面的名词的内容.

连接词通常为that，但在从句中不作任何成分，只起连接作用，但不能被省略，

定语从句：对先行词起修饰限制作用,并且关系代词that在句中常作句子的主语，宾语◆同位语从句通常由that引导，但what,why,whether,when,where,how等有时也可引导同位语从句。如：

Ihavenoideawhenshewillbeback.Itisverydifficulttoansweryourquestion

howIdidit.◆同位语从句有时不直接跟在被修饰的名词后面，而是被其它成分隔开了。如：
