复习名词性从句当一个从句的性质相当于一个名词,并在主从复合句中作主语、宾语、表语或同 位语时,这个从句被称为名词性从句。一、名词性从句的分类名词性从句包括主语从句、宾语从句、表语从句和同位语从句。二、名词性从句的引导词名词性从句的引导词可以分为三类:从属连词(that、whether、if等)、连接代词 (what、which、wh、whm、whatever、whichever、whever、whmever、 whse等)和连接副词(when、where、hw、why、whenever、wherever等)。
1.从属连词that的用法情景导学That he is still alive is sheer luck.他还活着纯粹是幸运。Jhn said that he was leaving fr Lndn n Wednesday.约翰说他星期三要去伦 敦。The teacher tld the students (that) they shuld hand in their hmewrk the next day and that the hmewrk must be signed by their parents.老师告诉学生们他们应该第 二天交作业,且作业必须由父母签字。The fact that he has fully recvered makes me happy.他完全康复了的事实令我高 兴。
用法归纳(1)that引导名词性从句时,只起①　　     作用,在从句中不作任何成分,也没有词 义。(2)that引导名词性从句时的省略问题:a.that引导的主语从句位于②　　    时,that不可省略。b.当动词后带有一个that引导的宾语从句时,that可省略;当动词后带有多个that引 导的宾语从句时,第一个that可以省略,而其他的that一般③　　    省略。c.当that引导的宾语从句前有it作形式宾语时,that一般不可省略。d.当that引导的宾语从句是以that/this作主语时,that常不可省略。e.引导表语从句和④　 　    从句时,that一般不可省略。
2.从属连词whether/if的用法情景导学Whether there is life n the mn is an interesting questin.月球上是否有生命是个 有趣的问题。The questin is whether this idea can be put int practice.问题是这一想法是否能付 诸实践。Everything depends n whether we have enugh mney.一切都取决于我们是否有 足够的钱。
用法归纳(1)if/whether引导的名词性从句是由一般疑问句或选择疑问句转化而来的, whether与if表示“⑤　　    ”,只起连接作用,引导从句,在从句中不作任何成 分。(2)whether和if有时可互换,但在下列情况下,只可用whether:a.引导⑥　　    从句并放在句首时。b.引导⑦　　    从句和同位语从句时。c.引导的从句作介词的⑧　　    语时。d.后紧跟r nt时。
3.连接代词wh、whm、whse、what、which等和连接副词where、why、 when、hw等的用法情景导学D yu knw whm they are lking fr?你知道他们在找谁吗?I dn’t knw wh did it.我不知道这件事是谁做的。When we shall meet again is unknwn.我们什么时候会再见是未知的。
用法归纳连接代词、连接副词引导的名词性从句由特殊疑问句转化而来。它们的特点是:(1)连接代词、连接副词保留自己的疑问含义。(2)连接代词在从句中充当句子成分,如⑨　　    、⑩　　    、定语,连接副词在 从句中作 　　    。(3)连接代词、连接副词引导的从句一律用 　 　    语序,不能用疑问句语序。
4.whatever、whever、whenever的用法情景导学I will just say whatever cmes int my mind.我想到什么就会说什么。Whever breaks the rules will be punished.任何违反规定的人都会受到惩罚。
用法归纳whatever、whever、whenever可引导 　　    从句、宾语从句和表语从句,并在从句中作 　　    、宾语、表语等。在此用法中whatever、whever等在从句中通常不含疑问意义。whatever=anything that; whever=anyne wh。
5. it作形式主语或形式宾语的名词性从句情景导学It is quite clear that the whle prject is dmed t failure.It is nt yet decided wh will d that jb.It is still unknwn which team will win the match.I think it best that yu shuld stay here.I like it when peple are pen and straight.We need t see t it that the guests are satisfied with us.
用法归纳(1)that引导主语从句时,通常用 　　    作形式主语,而将that从句置于句末。(2)which、wh、what等引导主语从句且从句较长时也常用 　　    作形式主语,而将真正的主语置于句末。(3)动词think、find、feel、cnsider、make等后面有 　　　　　    时,常使用it作形式宾语,而将真正的宾语移至句末。(4)表示喜爱、憎恶等感情的动词enjy、hate、lve、like、dislike和表示认为的 词take、have以及表示确保的see t后不能直接跟宾语从句,需用it作形式宾语,再 跟宾语从句。

3.whether/if　考查宾语从句。句意:她问我是否已经把书还给图书馆了,我承认我还没有(归还)。　　　 　　　I had returned the bks t the library作asked的直接宾语,结合句意可知此处表示“是否”。故填whether或if。 4.that　考查主语从句。本句使用了“It is estimated that...”句型,其中It是形式主语,that引导的从句作真正的主语。故填that。
