九、名词性从句.ppt

第九节　名词性从句 考点一　主语从句 1．(2011·高考江西卷)The villagers have already known________we’ll do is to rebuild the bridge. A．this　　　　　　　　　 B．that C．what D．which 解析：选C。本题考查名词性从句的用法。句意：村民们已经知道我们将要做的就是重建这座桥。分析句子成分可知have already known后为宾语从句。而在该宾语从句中又含“________ we’ll do”这一主语从句，该主语从句缺少宾语，且表“事物”，故用what引导。 2．(2011·高考北京卷)________ Barbara Jones offers to her fans is honesty and happiness. A．Which B．What C．That D．Whom 解析：选B。本题考查主语从句。句意：Barbara Jones展现给她的粉丝们的是诚实和快乐。what引导主语从句，在从句中作offers的宾语。which引导名词性从句需有一定范围可供选择，如：Which do you prefer，tea or coffee? 茶和咖啡你更喜欢哪个？故排除；that引导名词性从句不作成 分，故排除；whom用来指人，也应排除。 3．(2011·高考重庆卷)It is still under discussion________the old bus station should be replaced with a modern hotel or not. A．whether B．when C．which D．where 解析：选A。本题考查名词性从句。句意：那个旧公交车站是否应该被一家现代化宾馆所取代仍在讨论中。“It”作形式主语，“________the old bus station should be replaced with a modern hotel or not”作真正的主语。根据句意及题干中的“or not”可知答案 为whether，“whether...or not”在名词性从句中意为：是否。 主语从句在主句中作主语，位于主句谓语动词之前，但多数情况下由it作形式主 语，而把真正的主语放在句子的后面， 其句型结构为：It ＋be＋n./adj.＋that/whether/why/when＋从句。 (2010·高考陕西卷)It never occurred to me that you could succeed in persuading him to change his mind. 我真的没有想到你能说服他改变主意。 (2010·高考浙江卷)It is uncertain what side effect the medicine will bring about，although about two thousand patients have taken it. 尽管说已经有两千名病人服用了这种药品，但是，这种药品会带来什么副作用还不明确。 Whether there are living creatures in the outer space as those on Earth hasn’t been proved up to now. 外太空是否存在像地球上一样的生物迄今尚未确定。 考点二　同位语从句 1．(2011·高考辽宁卷)When the news came ________ the war broke out，he decided to serve in the army. A．since　　　 B．which C．that D．because 解析：选C。本题考查同位语从句。句意：当战争爆发的消息传来时，他决定参军。“the war broke out”作the news的同位语，该同位语从句不缺任何成分，用that引导，故答案为C项。 2．(2011·高考上海卷)There is clear evidence________the most difficult feeling of all to interpret is bodily pain. A．what B．if C．how D．that 解析：选D。考查同位语从句。句意：有确凿的证据表明，所有感觉中最难演绎的是身体上的痛苦。分析句子结构可知空格处引导的是evidence的同位语从句，从句结构和意义完整，故用that引导。 3．(2012·洛阳市检测)All of Manhattan，parts of Brooklyn and Queens are black
