高中英语-名词性从句常见错误例析和练习(含答案)
英语语法：名词性从句常见错误例析1. 【误】He will come back surprises all of us.【正】That he will come back surprises all of us.【析】that引导名词性从句时,尽管无意义也不充当成分,但除了在动词后引导单个宾语从句时可省略外,其它情况不能省略。
2. 【误】That he really means is what he doesn’t agree with us.【正】What he really means is that he doesn’t agree with us.【析】that和what均可引导名词性从句，区别在于：what在名词性从句中作主语、宾语或表语，而that在名词性从句中不作任何成分，只起连接作用。
误句的主语从句应该用what作means的宾语，表语从句中应该用that，that在从句中不作任何成分。
3. 【误】The news which our team had won pleased everyone.【正】The news that our team had won pleased everyone.【析】which在此句中不充当成分，说明从句不是定语从句而是同位语从句。
同位语从句不能用which引导，故改为that。
4. 【误】The reason why he failed in the exam was because he was too careless.【正】The reason why he failed in the exam was that he was too careless.【析】主语为reason时，引导表语从句的关联词一般用that，不用because，构成The reason why/for which/that/for .. . is that . . 句型。

根据In the past decade,在最近的几十年里，可知句子用现在完成时态，our education system是句子的主语，单数形式，所以第一空填has focused；第二空是主语从句做主语，if是否，不能引导主语从句，所以第二空填whether。
故选C。
【点评】主语从句主要有三类：1）（1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。
例如：That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。
（2）用连词whether 引导的主语从句:whether有含义（是否）,在句中不做成分,不可以省。
例如：Whether she is coming or not doesn't matter too much.她来不来都无关紧要。
注意：if不能引导主语从句。
2）用连接代词引导的主语从句（在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分）.例如：What you need is more practice.你所需要的是更多的训练。
3）用连接副词when, where, why, how引导的名词性从句（其连接副词有含义,在句中作状语。
）例如：Where we should leave it is a problem.9．Located between the 16th and the 18th floor, ______ I call my “home” is more like a “bird's nest”.A. whichB. thatC. whatD. where【答案】 C【解析】【分析】考查主语从句。
What引导主语从句______ I call my “home”且 What在从句中充当call的宾语。
故选C。
10．____ made me more unhappy was ___ the boy asked my friend to be his girlfriend and she agreed.A. What; thatB. That ; thatC. What; whetherD. It; that【答案】 A【解析】【分析】句意：让我更不高兴的是那个男孩要求我的朋友做他的女友，她同意了。
第一空填what,它一方面在句子中引导主语从句,另一方面又在主语从句中作主语；第二空用that引导表语从句且从句中不缺成分,表示对前面情况的说明。
故选A。
【点评】考查了名词性从句，本题涉及what引导的主语从句以及that引导的表语从句。
11．_______ you don't like him is none of my business.A. WhatB. WhoC. ThatD. Whether【答案】 C【解析】【分析】句意：你不喜欢他，跟我没有什么关系。
you don't like him为主语从句，其内容已经是完整的，所以用that，且引导主语从句的that不能省略。
12．________ the weather will not clear up until next week is bad news for us.A. AsB. IfC. WhetherD. That【答案】 D【解析】【分析】考查主语从句。
句意：直到下周天气才放晴，这对我们来说是坏消息。
此处是that引导的主语从句，that无实义，只其引导作用，故答案为D。
【点评】主语从句属于名词性从句，在名词性从句中，that无实义，只起连接作用，不做句子成分；if/whether起连接作用，不做句子成分，有实义“是否”。
做题时注意看从句是否少成分。

根据句意可知，句子主语是一个主语从句，引导词即起引导作用又要做从句的一个成分，所以第一空填What；第二空是that引导的表语从句，只起引导作用，故选B。
【点评】考查名词性从句，本题涉及关系代词what引导的主语从句和表语从句的应用。
