高三英语一轮复习语法专题——名词性从句活动单
复习目标：1.熟练掌握各连接词、连接代词、连接副词在句子中的选择与运用；
2.准确巧妙地在语段中使用名词性从句。
在复合句中起名词作用的从句叫作名词性从句。它包括主语从句、宾语从句、同位语从句和表语从句。名词性从句是英语中的一个重要语法项目，在历年的高考中几乎都涉及到。引导名词性从句的连接词可分为三类：连接词that，whether，if(不充当从句的任何成分)；连接代词what，whatever，who，whoever，whom，whose，which；连接副词when，where，how，why。

重难点突破一：名词性从句what和that的比较选用
(1) —What a mess! You are always so lazy!
—I’m not to blame, mum. I am ________ you have made me.
A. how B. what C. thatD. who
(2) Experts believe ________ people can waste less food by shopping only when it is necessary.
A. whyB. whereC. that D. what
☆【规律点睛】☆
________引导名词性从句时，在从句中不充当任何成分，也没有任何含义；
________引导名词性从句时在从句中要充当一定的句子成分，如主语、宾语、表语等。 试比较：
（1）_________ he considered a great proposal was turned down by the boss at the meeting.
（2）_________ Putin visited China led to the closer relationship between the two countries. ☆【特别提醒】☆
①what相当于“名词或代词＋that/which”；
②what不能引导定语从句
③介词后不接that从句，除了in that...和except that...。
④that引导两个以上的宾语从句，第一个that可省略，其后的that都不可省略。that引导主语从句、表语从句和同位语从句时，that不可省略。
☆【巩固提升】☆
①The school is no longer ________ it used to be.
＝The school is no longer the one________ it used to be.
②Finally he told us everything ________ he had seen.
＝Finally he told us ________ he had seen.
③They arrived in ________ was once a school.
＝They arrive in the place ________ was once a school.
④Don't care ________ others think about you.
⑤Do you know ________ they do with waste paper?
重难点突破二：It is...和There is...
It is...句型中it为形式主语，真正的主语为动名词、不定式或从句，而There is意为“有??”，有时be也可以用exist，remain等替代。
①________ is a pity that he was absent.
②________ is a fact that he has lied to you.
③________ is no wonder that he is so excited.
④________ is no need to worry about it.
⑤________ is no sense/point (in) arguing with him.
⑥________ is no doubt that he has gone.
⑦________ is no use complaining about life.
⑧________ is a waste of time surfing the Internet.
