2017届高考英语一轮复习语法备考：名词性从句（含解析）

　　名词性从句考点

　　◆典型陷阱题分析◆

　　1. She was so angry and spoke so fast that none of us understood _______ he said meant.

　　A. that B. what

　　C. that that D. what what

　　【陷阱】可能误选B。许多同学一看选项首先就排除了C和D，认为这样两个“引导词”叠用的情况不太可能。在A和B两个选项中，选项A肯定不行，因为它引导宾语从句时不能充当句子成分，所以便选择了B。

　　【分析】正确答案选 D。第一个what 用作动词 meant 的宾语，第二个what 用作动词 said 的宾语，即在 none of us understood what what he said meant 中，none of us understood 为主句，what what he said meant 为宾语从句，而在此宾语从句中又包括有 what he said 这样一个主语从句。

　　2. After _______ had happened he could not continue to work there.

　　A. which B. how

　　C. what D. having

　　【陷阱】可能误选A。

　　【分析】最佳答案选 C。有的同学误选A，是因为认为介词后应接关系代词 which，但实际上，若填关系代词，其前没有先行词，这根据不是一个定语从句。另外，由于 had happened 缺主语，所以B和D也不能选。请再做下面一题(答案选B)：

　　He pointed to ______ looked like a tomb and said, “Ghost.”

　　A. that B. what

　　C. which D. as

　　3．“Is ______ you want to say?” asked the teacher.

　　A. this B. that

　　C. all that D. that all

　　【陷阱】根据中文字面意思误选A或B。

　　【分析】最佳答案选 D。假若选A或B，那么转换成陈述句即为：This is you want to say. / That is you want to say. 显然句中的两个谓语动词 is与want相冲突。选D组成的句子是 Is that all you want to say? 其中的that 为句子主语，all 为表语，you want to say 为定语从句，用以修饰all。

　　4. “When ______ leave for Japan?” “When ______ leave for Japan is kept secret.”

　　A. they will, will they B. will they, they will

　　C. they will, they will D. will they, will they

　　【陷阱】可能误选D，认为 when 后应用疑问句词序。

　　【分析】最佳答案选 B。第一个when引出的是一个特殊疑问句，故用疑问词序；第二个 when 引出的是主语从句，故其后用陈述句词序。请做以下试题(答案选C)：

　　(1) None knows if _______ that boy, but if _______ him, her parents will be disappointed.

　　A. she will marry, she will marry B. she marries, she marries

　　C. she will marry, she marries D. she marries, she will marry

　　(2) “Where _______ go to work?” “Where _______ go to work is not known.”

　　A. we shall, we shall B. shall we, shall we

　　C. shall we, we shall D. we shall, shall we

　　5. Someone is ringing the doorbell. Go and see ______.

　　A. who is he B. who he is

　　C. who is it D. who it is

　　【陷阱】几个干扰项均有可能误选。

　　【分析】此题最佳答案为D。首先可以排除A和C，因为空格处实为一个宾语从句，所以不能用疑问句词序。另一方面，但按英语习惯，当用于指代身份不明的人时，要用代词it，而不用 he 或she等。比较以下两句：

　　Mr Smith is at the door. He wants to see you. 史密斯先生在门口，他想见你。

　　Someone is at the door. It may be the postman. 有个人在门口，可能是邮递员。

　　第一句因前面指明了是 Mr Smith，所以后面用代词 he；而第二句因前面用的是不定代词 someone，说明此人身份尚不明确，故其后用了代词 it 来指代。

　　6. Don’t you know, my dear friend, ______ it is your money not you that she loves?

　　A. who B. which

　　C. that D. what

　　【陷阱】此题容易误选 A或B：选 A 的同学认为这是指人的，故用who；选B的同学认为这是非限制性定语从句，两者都是误认为这是定语从句(注意没有先行词)。

　　【分析】其实答案应选C。that引导的是一个宾语从句，用作动词 know 的宾语，它只是被句中的插入语 my dear friend 隔开罢了。请做以下试题(答案均为C)：

　　(1) Everyone knows, perhaps except you, _______ your girl-friend is a cheat.

　　A. who B. which

　　C. that D. what

　　(2) I think, though I could be mistaken, ______ she liked me.

　　A. who B. which

　　C. that D. what

　　(3) He told me the news, believe it or not, ______ he had earned $1 000 in a single day.

　　A. that B. which

　　C. as D. because

　　前面两题 that 引导宾语从句，后面一题 that同位语从句(修饰the news)。

　　【答案与解析】

　　1. 选D。what made matters worse 是主语从句(注意其后有谓语动词was)，相当于 the thing that made matters worse。

　　2. 选A。what 引导的是表语从句，相当于 the thing that it takes to do anything well。

　　3. 选C。that 引导的是一个主语从句，句首的it为形式主语。

　　4. 选 C。答句为省略句， I was trying to prove to the police where I was last night， where 引导的是一个宾语从句。类似地，下面选 C：

　　“_______ made her struggle to become an artist so hard?” “______ she was a woman.”

　　A. What, What B. That, That

　　C. What, That D. That, What

　　5. 选D。what 引导的是表语从句，what 在此相当于 the things that。

　　6.

　　C。句首的 it 是形式主语，该that 引导名词性从句时不能充当句子成分 A。第一空填 what，是因为该 understand 缺宾语；why 和 because 均可引导表语从句，其区别是： why 引导表语从句强调，because 引导表语从句强调， why。

　　8. B。what 在此， the thing that。

　　9. what，均用于引导宾语从句，因为两个said 和

　　10. 选 A。what 引导

　　11. 选 A。I can to save them 为 I can do to save them 之略，此句中的 do ，故选 whatever

　　12. 选 B。that 在此引导主语从句，无词义，也不充当句子成分。注意不要根据中文意思选 D，因为 because 不用于引导主语从句。

　　13. 选 B比较 That’s why… 与 That’s because…：前者用于强调，

　　I got wet all through. _______ I had neither a raincoat nor an umbrella.

　　A. It’s the reason B. That’s why

　　C. There’s why D. That’s because

　　15. 选 D is worth praising 这一谓语可知前面是主语从句， B 项和 C 项；whoever “任何……的人”， anyone who。

　　16. 选 A。how 引导主语从句，that 引导同位语从句。
