专题十五 名词性从句易错点集锦
名词性从句的句法功能相当于名词词组，在句中充当主语、宾语、表语、同位语、介词宾语等。因此名词性从句又分为主语从句、宾语从句、表语从句和同位语从句。
类别 功 能 引 导 词
从属连词 只起连接作用，不充当句子成分 that, whether, if
连接代词 起连接作用，并充当主语、宾语、表语或定语 who, whom, whose, which, what, whatever, whichever, whoever
连接副词 起连接作用，并充当从句状语 when, where, how, why
一、主语从句的易错点
主语从句的一般结构 主语从句＋谓语动词＋其他 How the book will sell depends on its author. That he is the best student in the class is obvious.
it作形式 主语时的 主语从句 It+be/becomes/became+形容词／名词／过去分词＋主语从句 It is still a question whether she will come or not. It became clear that Mary did make a mistake.
It seems/ appears/ happens等动词＋that 从句 It seems strange that he should have done a thing like that. It happens that he can understand a little about the language.
It remains to be+过去分词＋主语从句 It remains to be seen who will be the victor in the contest.
It doesn't matter +how/whether 从句 It doesn't matter whether he is wrong or not. It doesn't matter much whether we go together or separately.
用来表示惊奇、怀疑、惋惜、理应如此等语气时，主语从句谓语动词用（should) do 形式 It is necessary /important / natural /strange等＋that 从句 It is necessary that one(should)obey the law.
It is suggested /requested /proposed/desired等＋that从句 It is suggested that you (should) attend the opening ceremony.
二、宾语从句的易错点
动词后的 宾语从句 主语＋及物动词＋宾语从句 I know that he is an honest boy. Can you tell me how I can get to the zoo I wonder if/whether you have told the news to Li Lei. They asked what Jean was doing now. Do you know who has won Red.Alert game
feel, think, find, consider, make等，常用it作形式宾语，宾语从句后置 I find it important that.we should keep calm in danger. You may think it strange that he would live there. I feel it a pity that I haven't been to the get-together. I have made it a rule that I keep diaries.
like, dislike, love, hate, enjoy, appreciate等不能直接跟宾语从句，必须用it作形式宾语，后接宾语从句 I like it that everyone passed the exam. I hate it when they talk with their mouths full of food.
think, believe, suppose, 等词后的宾语从句若是否定的，否定词要转移到主句的谓语动词上 I don't think your answers are right. I don't believe that man is killed by Jim, is he
介词后的宾语从句 介词后可接宾语从句，但连接词whether 不可换作if He often thinks of how he can make his class lively. She worries about whether she's really good enough.
非谓语动词之后的宾语从句 不定式、v.-ing形式、过去分词后也可以接宾语从句 I'd just tried to do what I could for you. I suggest eating what is fresh.
宾语从句中的时态 主句谓语动词为一般现在时，从句时态根据实际情况而定 Do you know when the ancient games began
主句谓语动词是一般过去时，从句的时态一般用适当的过去时态 He asked me if I was reading the textbook when he was in.
当宾语从句为客观真理和规律时，则用一般现在时 He said that light travels faster than sound.
whether与if引导宾语从句的区别 与 or not 连用时，只用 whether I want to know whether or not the train goes to King Street.
＂whether+不定式”结构作宾语，相当于一个宾语从句；if无此用法 I don't know whether to go there.
介词后面的宾语从句中只用 whether I'm not interested in whether he has a lot of money.
if引导的条件句中，如果再有表示“是否”的引导词引导宾语从句时，只用 whether He asked me whether I'd move to Beijing if I got the job.
doubt 在肯定句中，接 whether 和if引导的宾语从句；但在否定句中，只用 that We don't doubt that he is a brave man. I doubt whether/if Jack could manage a sailing boat.
三、表语从句的易错点
表语从句常位于连系动词be, look, remain, seem等之后，其连接词还有as if/though,because等
主语＋系动词＋表语从句 The trouble is that we are short of money. He looked just as he had looked ten years before. The question is whether they will be able to help us. The problem is who we can get to replace her. I think it is because you are doing too much. The question is which of us should go.
because 引导表语从句强调原因，why引导表语从句强调结果 It's because you're careless. That is why stone walls are used instead of fences around New England fields.
the reason why 从句＋be + that 从句 The reason why he was absent was that he was ill.
what 从句＋be+that从句 What comforted the young mother was that the baby came to life.
It looks/seems as if/though 从句 It looks as if it is going to rain. At that time, it seemed as if I couldn't think of the right word anyhow.
主句主语是advice, demand, suggestion, order，requirement, idea, request，command等时，表语从句用虚拟语气，即谓语动词用（should)do 形式 My advice is that you(should)quit smoking. My suggestion is that we(should)start early tomorrow. Our only request is that this(should)be settled as soon as possible.
四、名词性从句其他易错点
that与what在名词性从句中的区别 what 充当成分，意为...的事物不可省略；that 不作任何成分，只起连接作用，也无实际意义，有时可以省略 I only knew(that)he was studying in a western country,but I didn't know what country he was in. What you need is more practice. That you will win the medal seems unlikely.
名词性从句已有疑问引导词时，不再用that I don't understand what you said just now.(understand 后不再用 that)

1.whoever 解析：句意：每年，无论谁做出最漂亮的风筝都将会在风筝节获奖。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。

4.how 解析：分析句子结构可知，这是一个宾语从句。根据形容词thick 及结构可知，这里的意思是“印第安人要算出土坯墙的确切厚度”。空后为形容词，因此空处应用副词，故填how。
5.what 解析：句意：如果你去河里或湖里游泳，一定要调查清楚水面下有什么。经常有岩石或树枝隐藏在水下。所填词在此处引导宾语从句，并在从句中作主语，故填what。

6.that 句意：在这个时候开始新的一年的历史原因是这个时间在秋收和春季耕地、播种之间。换言之，它是一年的艰苦劳作之后休息、放松、庆贺的时间。从句不缺成分，不缺含义。The reason is that...为固定句式， 故填that。
7.that 句意：最近， 在一本流行杂志中， 有一项新的研究表明好闻的气味有可能减少疼痛。设空处引导同位语从句，对possibility进行解释说明，且从句中不缺成分，意义完整， 故填that

14.It 句意：人们预测，当现有的人力交通运输系统被证明效率低下时，小型自动巴士可能会产生影响。根据句意以及句子结构可知，设空处为形式主语，真正的主语是that从句， 故用It作形式主语。

20. The problem is whether one less hour of sleep is not equal to an extra hour of achievement.
【答案详解】
16. if→whether 解析：if和whether都可引导名词性从句意为“是否”，但日受到很多限制，例如不能位于句首，介词后的宾语从句不能用让引导，不能跟or not连用等。故if改为whether。
17.which→where 解析：分析句子结构可知，句中is后接表语从句， 引导词在从句中作地点状语， 故用where， 表示“英语就是我的强项所在(之处)”。
18.because→that 解析：考查名词性从句。主语为名词reason，表语从句中的连接词要用that。
19.why→how 句意：在伦敦，我注意到的最大的文化差异之一是伦敦人是如何为人的。根据语境可知，此处用how引导表语从句， 表示方式。
20.whether→that 句意：问题是少睡一小时不等同于额外的一小时的成就。分析句子结构可知，is后为表语从句，从句的结构和句意完整，没有whether“是否”的含义，that在此只起结构连接作用。
