* 专题七　名词性从句 考向分析 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。高考对名词性从句的考查主要体现在对what,that,whether,whatever,whichev-er,when,where,how等引导词的考查上,其中what和that是考查的重点。 考点清单 一、主语从句 单句填空 1.Every year, 　 whoever ?? makes the most beautiful kite will win a prize in the Kite Festival. 答案　whoever　句意:每年,在风筝节上,制作出最漂亮的风筝的人会赢得一份奖品。设空处引导主语从句,从句中缺少主语成分,且表示“无论谁”,故填whoever。 语境运用 2.Your support is important to our work. 　 Whatever ?? you can do helps. 答案　Whatever　句意:你的支持对我们的工作很重要。你做的任何事情都有帮助。本题考查主语从句。“　　????you can do”为主语从句,该从句缺少宾语,且表示“任何事情”,故答案为Whatever(相当于Any-thing that)。 3.It is often the case 　that????anything is possible for those who hang on to hope. 答案　that????句意:对于那些总是不放弃希望的人来说,发生任何事情都是有可能的,这是很常见的。考查主语从句。本句中it为形式主语,“????　????anything is possible for those who hang on to hope”为真正的主语;该从句结构完整,故由that引导。 单句改错 4.It is obvious to the students what they should get well prepared for their future. ?? what→that ?? 答案　what→that　在题干中,it为形式主语,真正的主语为students之后的主语从句,从句中不缺少句子成分,且句意完整,故用that作为引导词,what应改为that。 1.名词性从句的引导词:①that,if,whether等;②连接代词what,which,whom,who,whose,whatever,whichever,whoever等;③连接副词when,where,why,how等。 2.主语从句常位于谓语动词之前,但是有时为了保持句子平衡,会使用it作为形式主语,而把真正的主语放在后面,常见的有: ①It+be+名词+that从句(如It is a fact/pity/shame/surprise that...;It is no wonder that...); ②It+be+形容词+that从句(如:It is clear/important/necessary/obvious/pos-sible/strange that...;It is known to all that...); ③It+be+过去分词+that从句(如It is believed/reported/said/suggested/thought that...); ④It+特殊动词+that从句(如It happens that...;It occurred to sb. that...;It doesn’t matter how/whether/what...)。 用法精讲 二、宾语从句 单句填空 1.She asked me 　 whether/if ?? I had returned the books to the library, and I admitted that I hadn’t. 答案　whether/if　句意:她问我是否已经把书还给图书馆,我承认我还没有归还。设空处引导的是宾语从句,根据句意可知该宾语从句要用whether/if引导。 2.We choose this hotel because the price for a night here is down to $20, half of 　 what ?? it used to charge. 答案　what　句意:我们选择这家宾馆是因为这里住一晚上的价格降到了20美元,(20美元)是其过去收费的一半。本题考查宾语从句。逗号后面是$20的同位语,charge后面缺少宾语,故用what引导。 语境运用 3.Jane moved a
