1. D。分析句子结构可知，空白处后面为句子主语“Evidence”的同位语从句，在这一从句中，句意完整，不缺少成分，应该使用“that”作为引导词。因此，正确答案为D选项。
2.C。that引导同位语从句，在从句中不做句子成分，补充说明同位语promise的内容。
3. B。句意为：会议将被延期的通知大约下午两点钟来。空格后的句子是解释说明名词the notice，作同位语从句，在从句中不做任何成分，所以用that引导。
4. C。题意：抽烟会导致多种疾病，对此现代科学已经给出了明确的证据。本题考查同位语从句。evidence后的从句说明的是其具体内容，从句中不缺少句子成分，故用that引导同位语从句。其他三项引导同位语从句都要在从句中作成分。
5. D。本题考查表语从句的连接词。句意：我觉得与其说他是个实干家不如说他是个空谈家，这就是为什么他从来不会完成任何事情的原因。分析句子结构可知，which引导非限制性定语从句，which指代前面的整个句子he’s more of a talker than a doer；在定语从句中，is后面为表语从句，由句意可知which指代的内容是表语从句内容的原因，故用why引导表语从句。
6. D。分析句子结构，that’s后面所带从句为表语从句；再看从句中do为及物动词，需要填入宾语，故填入连接代词what。
7. A。“这就是我不同意的地方。”agree是不及物动词，所以用where引导表语从句。
8. B。从句不缺成分，因此用that来引导。句意：狄更斯喜欢他自己的小说《大卫·科波菲
尔》的部分原因是小说创作非常贴近他本人的真实生活。
知识讲解
表语从句的连接词判断
表语从句就是用一个句子作为表语，说明主语是什么或者怎么样，由名词、形容词或相当于名词或形容词的词或短语充当，和连系动词一起构成谓语。
连接表语从句的连接词有：that, what, who, when, where, which, why, whether, how
The problem is how we can get the things we need.
The scissors are not what I need.
【高清课堂链接点：表语从句高清ID：396513 】
表语从句一般位于连系动词（如be，seem，remain等后）。
The fact is that she never liked him.
My point is that you have to face the problem.
The question is whether we should accept their invitation.
The city is no longer what it used to be.
That’s where the battle took place.
The question is who’s responsible for what has happened.
The reason why he was absent was that he was ill.
as if引导的表语从句有时可用虚拟语气，表示可能性小。
He acted as if he hadn’t eaten for a long time.
It looks as if it is going to rain.
表示建议、命令、要求一类的表语从句要用虚拟语气。
My suggestion is that you should practice reading English every day.
The order is that you stay where you are.
His request is that his brother play with him.
The requirement is that you should not smoke in that school.
表语从句重点句型
“That is why...”是常用句型，意为“这就是……的原因”，其中why引导的名词性从句在句中作表语，该句型通常用于针对前面已经说明过的原因进行总结。
That is why I came.
That's why he got angry with me. （That's why…强调结果）
because引导的表语从句强调原因。
That's because he didn't understand me.（That's because…强调原因）
what引导的主语从句表示结果或名词reason作主语时，后面的表语从句表示原因时要用that引导，不宜用because。
The reason why I was sad was that he didn't understand me.
What I told him yesterday was that he had been promoted as the manager of the company.
同位语从句的连接词
同位语从句对名词进一步解释，说明名词的具体内容，它一般跟在抽象名词fact，idea，news，hope，belief，thought，truth，doubt，suggestion，warning, instruction，reason，information,
question等之后，对这些名词进行说明或解释。引导同位语从句的词除连词that，whether 外，还有连接代词what, which, who, 以及连接副词how，when，where，why等。
The king’s decision that the prisoner would be set free surprised all the people.
He made the suggestion that we go by train.
There is no doubt that he is guilty.
由that，whether引导的同位语从句。
Information has been put forward whether more middle school graduates should be admitted into universities.
由连接代词引导的同位语从句。
The question who should be the first has not been settled.
由连接副词引导的同位语从句。
I have no idea when he will be back.
同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。
He got the news from Mary that the sports meeting was put off.
同位语从句常用句型
The news comes that...
Word comes that...
The story goes that...
Here is the fact that...
I have no idea what / when / how / where...
We are faced with the problem that/ whether/ when/ how...
We still hold the belief that...
There is little hope that...
Is there any possibility that...?
同位语从句与定语从句的区别
定语从句中的that既代替先行词，同时在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述它的性质或特征。同位语从句是名词性的，其功能是对名词进行补充说明。
The news that he told me is that Tom would go abroad next year.
（第一个that引导的从句是定语从句，that在从句中作宾语）
The news that Tom would go abroad is told by him.
（同位语从句，that在句中不作任何成分）
引导名词性从句的that和what的区别
that 引导名词性从句时，在从句中不充当任何句子成分，也没有任何含义，只起连接作用, 且在宾语从句中有时可省略；而what引导名词性从句时，在从句中充当主语、宾语、表语或定语。
That he said so made us angry .
What he said at the meeting made us angry.
China is no longer what it used to be.
名词性从句的解题规律
四种名词性从句都需要有一个连接性词在从句的开头。这个词是什么性质，要看它在从句中所作的成分，如果作的是主语、宾语、表语的话，这个词就是连接代词；如果作的是各种状语，就叫连接副词；如果不作任何成分，就叫连接词。
连接词：that, if, whether
连接代词：who, whom, what, whose, which, whichever, whatever, whoever
连接副词：when, where, how, why
解题步骤：
1. 根据选项特点、句子结构判断从句类型；
2. 分析从句结构是否完整，成分残缺，选连接代词；成分完整，选连接副词。
从句事实确定→that;
不确定→whether/ if
强调时间→when/ whenever
强调程度修饰a./ adv →how/ however
强调地点→where/ wherever
强调原因→why
从句缺定语→what/ whose
物→what
人→who/ whom/ whoever/ whomever
有指定范围→which/ whichever
缺宾语时，若表示“来自于何处？”→where

表语从句 1．定义：用作表语的从句叫做表语从句。 2．引导表语从句的关联词的种类： (1)从属连词that。在从句中不做成分。如：The trouble is that I have lost his address.麻烦是 我把他的地址丢了。The reason was that he was late for school. (2)从属连词whether,as,as if。如： (3)looked just as he had looked ten years before.他看起来还与十年前一样。 (4)question is whether they will be able to help us. 问题是他们是否能帮我们。 (5)注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如： (6)All this was over twenty years ago, but it’s as if it was only yesterday. (7)这都是20多年前的事了，但宛如昨天一样。 The key is whether we can solve the problem.注：能跟表语从句的谓语动词一般为系动词be, seem, look，sound等。如： (8)He looked just as he had looked ten years before. 他看起来还与十年前一样。 It sounds as if someone is knocking at the door. 连接代词who, whom, whose, what, which, whoever, whatever, whichever 在表语从句中做主语、宾语等。如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。 (9)That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。 The problem is who we can get to replace her.

10级A班第六组作业 同位语从句 一、同位语从句的概念在复合句中用作名词的从句叫同位语从句, 其主要用途就是对前面的名词做进一步解释说明该名词的具体内容。 可以跟同位语从句的名词通常就 是: news,fact,promise,question,doubt,thought,hope,message ,suggestion,word, possibility,order,fear,proof,belief,advise,demand,problem,request,truth,wish 例句: I just got word that he is not coming this evening 、 Wehaven 't yet settled the question where we are going to spend our summervacation 、The Mona Lisa is widely seen as proof that good looks can last for ever There is no doubt that he is guilty 、 There is great doubt whether he did so or not 、 二.同位语从句的先行词同位语从句的先行词通常就是抽象名词, 常见的有:idea, situation thought, fact, evidence, belief, doubt, fear, hope, question, theory, news, order, ability 例句: 等等。How did the cheats explain the fact that the Emperor didn't feel the new clothes in him? 皇帝觉得身上并没有穿上新衣, 对这个问题骗子就是怎样解释的? The news that his heath is failing made us sad 、 她健康状况不佳的消息使我们很难过。 I have no idea where they are spending their holidays 、我不知道她们在哪里度假。 The question who should do the work requires consideration 、谁该干这项工作的问题需要考虑 There is no doubt that he will come here again 、她会再来这里, 这就是毫无疑问的。He was tortured by the doubt whether he would accept their presents 、她被就是否接受她们的礼物这个疑虑所折磨着。 三.同位语从句的引导词 1、连词that 引导同位语从句 The idea that you can do this work well without thinking is quite wrong 、您认为不动脑筋就能做好这件工作的想法就是完全错误的。（作idea的同位语） He gabbed his suitcase and gave the impression he was boarding the Tokyo plane 她拿起了手提箱, 给人的印象就是她要登上飞往东京的飞机了。 以下名词常用于以上句型: advice, announcement, argument, belief, claim, conclusion, decision, evidence, explanation, fact, feeling, hope, idea, impression, information, knowledge, message, news, opinion, order, probability, promise, proposal, remark, reply, report, saying, statement, suggestion, thought, treat, warning, wish, word
简单句与宾语从句、表语从句、同位语从句英语语法培训教材
1简单句与宾语从句 (2) 1.1陈述句作宾语 (2) 1.2一般疑问句作宾语 (3) 1.3特殊疑问句作宾语 (3) 2简单句与表语从句 (5) 2.1陈述句作表语 (5) 2.2一般疑问句作表语 (5) 3简单句与同位语从句 (6) 3.1陈述句作同位语 (6) 3.2一般疑问句作同位语 (7) 3.3特殊疑问句作同位语 (7) 本章小结 (8) 1简单句与宾语从句 名词从句的本质是用三种句子（陈述句、一般问句和特殊问句）充当四种句子成分（主语、宾语、表语和同位语）。所以，当用三种句子充当另外一个句子的宾语时，就构成了宾语从句。因此，本节内容安排如下： 1.1陈述句作宾语 1.2一般疑问句作宾语 1.3特殊疑问句作宾语 1.1陈述句作宾语 把“that＋陈述句”这一结构放在宾语的位置即构成宾语从句。请看例句： 1We know(that) the world is round.我们知道，地球是圆的。 2I think(that) a sound knowledge of grammar is indispensable to good writing.我认为扎
实的语法功底对良好的写作极为重要。 需要注意的是，只有宾语从句中的that才可以省去（在不影响对句意的理解的情况下），而主语从句、表语从句和同位语从句中的that一般不能省去。 1.2一般疑问句作宾语 把“whether/if＋陈述句”这一结构放在宾语的位置即构成宾语从句。请看例句： 1I don't know if/whether he needs my help我不知道他是否需要我的帮助。 2No one knew whether or not interest rates would rise 没有人知道利率是否会提高。 这里原来的一般问句是would interest rates rise，变成陈述句语序后成为interest rates would rise，然后为了保留疑问的意义又添加了whether or not，于是便有了whether or not interest rates would rise，在主句的谓语knew后面作宾语，即构成宾语从句。需要提醒的是，因为一般不说if or not，所以这里的连词不宜用if，而要用whether。 注意：只有宾语从句才可以用if引导，主语从句、表语从句和同位语从句一般都要用whether引导。 1.3特殊疑问句作宾语 把特殊疑问句变成陈述句语序后放在宾语的位置即构成宾语从句。请看例句： 1I have not decided whom I should vote for我还没有决定该投谁的票。 这里的特殊疑问词whom是作vote for的宾语，所以需将原来的倒装句whom should I vote for调整为陈述句语序whom I should vote for，然后作主句谓语decided的宾语，即构成宾语从句。 2No one knows exactly how speech began没有人确切地知道语言是如何产生的。 这里的特殊疑问词how是作began的方式状语，所以需将原来的倒装句how did speech begin调整为陈述句语序how speech began，然后作主句谓语knows的宾语，即构成宾语从句。 3Could you tell me where the post office is? 你能告诉我邮局在哪里吗？
表语从句讲解及专项练习 概念：表语从句是在复合句中作表语的名词性从句。 放在系动词之后,一般结构是“主语+系动词+表语从句” 可以接表语从句的连系动词有be, look, remain, seem等。 ★ The trouble is that we are short of money.困难是我们资金短缺。 ★ That is why stone walls are used instead of fences around New England fields.这就是为什么在新英格兰用石头墙而不用栅栏的原因。 ★ At that time, it seemed as if I couldn't think of the right word anyhow.当时,我似乎怎么也想不出一个恰当的字眼来。 引导表语从句的词： 从属连词that、whether、as though、as if（That引导表语从句时，在口语中，间或可以省略。） 关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等； 关系副词when, where, why, how, however, whenever, wherever等。 ※由从属连词that，whether引导的表语从句。 that在引导表语从句时无词义，而whether有词义，意为、“是否”。这时主句的主语常常是些抽象名词，如question(问题)，trouble(麻烦)，problem(问题)，result(结果)，chance(可能性)，suggestion(建议)，idea(想法)，reason(理由)等。表语从句对主句主语进行说明、解释，使主语的内容具体化。 例如： ★ The trouble is (that) she has lost his money. 麻烦的事是他丢了钱。 ★The question is whether we need more ice cream.问题是我们是否还需要一些冰淇淋。 ★The problem was that it was too valuable for everyday use.问题是它作为日常之用太贵重了。 ★What she couldn’t understand w as that fewer and fewer students showed interest in her lessons. 我们不能理解越来越少的学生对他的课不感兴趣。 ※由关系代词引导的表语从句。 关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句，在句中作主语、宾语、表语，关系代词不能省略。 例如： ★The question is which of us should go.问题是我们哪一个应该去。 ★The problem was who could do the work.问题是谁能做这项工作。 ★That's what he is worrying about.那就是他在担心的事。

It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。如： It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。 B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that 从句。如： It’s a pity that we can’t go. 很遗憾我们不能去。。 C.It+seem, happen等不及物动词及短语+that从句。如： It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。 D.It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。如： It doesn’t matter whether she will come or not. 她是否来这无关紧要。 F. 当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句后置。如：Does it matter much that they will not come tomorrow? 他们明天不来很要紧吗？ G. 当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。如： How strange it is that the children are so quiet! 孩子们这么安静真奇怪！ 2．注意连接代词whoever, whatever, whichever等引导主语从句的含义 Whoever comes will be welcome. (whoever=the person who) 来的人将受到欢迎。 （二）表语从句 1．定义：用作表语的从句叫做表语从句。 2．构成：关联词+简单句 3．引导表语从句的关联词的种类：
Grammar—appositive clauses＆predicative clauses 名词性从句之同位语＆表语从句 同位语从句： I.明确概念与特征： 1. 同位语从句常放在名词之后，用来补充说明名词的具体内容。常用来接同位语从句的名词有news, idea, promise, question, doubt, wonder, fact, hope, wish, suggestion, advice, possibility, message, word, belief, information等。常用来引导同位语从句的连词有that, what, who, whether以及连接副词where, when, why, how 等。如： The news that their children couldn’t come back on time worried all the parents. I had no idea when the storm would end. 2. 不过有时候为了保持句子结构平衡，同位语从句也不一定直接放在名词后，而会出现隔离情况。如： Word came that the sports meet had been put off. Suddenly a good idea occurred to me that I could buy my teacher a gift. 3. 同位语从句前名词的数 同位语从句前的名词通常用单数形式，并且往往带有限定词加以修饰。如：Where did you get the idea that I could not come? Give me your promise that you will come to our party this evening. Exciting word came that I passed the exam. II. 正确选用引导词 一般来说根据句意来确定相应的引导词，并且从句要用陈述句的语序。 1.that引导同位语从句时在句中不作任何成分，但不可省略； The idea that we play football after class is great. 2.在表示是否的意思时连词只能用whether而不能用if； The question whether you can go to an ideal university depends on your effort. 3.从句若缺少主语,宾语或定语用连接代词（what, who, whom, whose, which），若缺少状语用连接副词（when, where, how, why）引导。 I have no idea which mobile phone is the best—it’s a matter of personal taste. At last I made a decision that I would never come back again. The question what we should do with this situation is under discussion. All of us had no idea why he refused our help. The question why he didn’t attend the meeting puzzled us. We can’t solve the problem how we can travel faster than light. 4.在名词doubt“怀疑”后的同位语从句用whether连接；在no doubt“不怀疑”之后的同位语从句用that连接。例如： There is no doubt that we will win the final match. I have a doubt whether he will finish the job on time. III. 注意从句中的时态 一般来说同位语从句的时态要和主句的时态保持一致。但在表示请求、命令、建议等意思的名词后的同位语从句中的谓语动词应用(should) do，(如demand, wish, suggestion, advice，order等)后面的同位语从句要用虚拟语气。如 I have no idea when he will be back. I accepted my father’s advice that I (should) apologize to my friend.
