二、知识讲解
知识点1 ：表语从句的概念
概念：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。
如：The problem is puzzling. 这问题令人困惑
主语连系动词形容词作表语
The problem is when we can get a pay rise. 问题是什么时候我们可以得到加薪.
主语连系动词一个句子作表语（表语从句）
注意：“主语+系动词+表语从句”。
常见的连系动词有：be动词(am, is, are, was, were)、表示持续的系动词（keep, remain, stay）、感官动词feel(摸起来，感觉) , smell(闻起来) , sound(听起来) , taste(尝起来，吃起来) 等、表示变化的系动词（become, grow, turn, fall, get, go,）、表终止的系动词prove, turn out(结果是，证明是)、seem, appear（看起来...）
注意：表语从句都用陈述句语序：
E.g.: The question is when he can arrive at the hotel
这个问题是他什么时候能到达宾馆。
That is what I want to tell you.
那就是我想要对你讲的。
知识点2：表语从句的引导词
引导表语从句的连接词分为三类：
（1）从属连词：that, whether, as if.(从属连词在从句中不但当成分，只起连接作用，that
无词义)
（2）连接代词：Who, whoever, whom, whomever, what, whatever, which, whichever, whose.
(连接代词在从句中充当主、宾、表、定的成分，起连接作用，有词义)
（3）连接副词：when, where, why, how等。
(连接副词在从句中充当状语的成分，起连接作用，有词义)
1、由从属连词that，whether，as if/as though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”，表语从句不能用if引导。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。
注意：as if/though的用法
as if/though“好像”，如果句中的情况与事实不相符，从句多用虚拟语气。
如果从句表示与过去事实相反时,谓语动词要用“had + 过去分词”；
如果从句表示与现在事实相反,谓语动词用一般过去式；
如果从句表示将来的可能性不大，用would (might ,could )+动词原形.
Li Lei is now in a new jacket. He looks as if he were an American boy. (与现在事实相反)
The girl is giving us a vivid description of the moon. It seems as if she had been to the moon many times. （与过去事实相反）
It looks as if it might rain. （与将来事实相反）
但是，如果as if/though引导的表语从句所表示的与事实相符，从句则用陈述语气。
The clouds are gathering. It looks as if is going to rain.
2. 连接代词：who/whom/whose/what/which/whoever/whatever/whichever/whomever，在表语从句中做主语、宾语、表语和定语。
Tom is no longer what he used to be. (what做表语)
The problem is who is fit for this job. (who做主语)
This is what I want to tell you. (what做宾语)
The problem is whose work is the best. (whose做定语)
3.连接副词：when/where/how/why，在表语从句中做状语。
The question is how he did it. 问题是他是如何做此事的。
The question is where we can live. 问题是我们能住在哪儿。
知识点3：表语从句的句型区分
1.reason做主语或主语中包含事件的起因时，后面的表语从句表示原因时要用that来引导，而不用because；
The reason is that he got up late.
2.That is why= That is the reason why
That is why she failed to pass the exam. 那就是她考试不及格的原因。(why 在表语从句中充当原因状语)
That is the reason why she failed to pass the exam. 那就是她考试不及格的原因。(why 在定语从句中充当原因状语)
3.That is because...
That is because I got up late. 这是因为我起床迟了。
知识点6：
表语从句的虚拟语气
当表命令、建议、坚持、要求等名词后跟的表语从句用虚拟语气：(should) + 动词原形。建议suggestion 、advice、proposal、recommendation;
要求demand 、desire、request;
命令order、command、requirement;
坚决主张insist;
E.g.：My suggestion is that the plan be put into practice. 我的建议是这个计划应该用于实践之中。

表语从句讲解及专项练习
15级计算机班英语 表语从句讲解 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, remai n, seem 等。 ★The trouble is that we are short of mon ey. 困难是我们资金短缺。 ★ That is why stone walls are used in stead of fen ces around NewE ngla nd 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 seemedas if I could n't think of the right word an yhow. 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； 关系畐【J词when, where, why, how, however, whenever, wherever 等。 探由从属连词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 mon ey. 麻烦的事是他丢了钱。 ★The questi on is whether we n eed 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 was that fewer and fewer students showed in terest in her lesso ns. 我们不能理解越来越少的学生对他的课不感兴趣。 探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 questi on 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 worryi ng about. 那就是他在担心的事。 ★That's what we should do. 那是我们应该做的。 ※由关系副词引导的表语从句。 关系副词when, where, how, why 除在句子起连接作用外，在从句中还充 当时间，地点，方式或原因状语，本身具有词义。
表语从句分析
一、定义： A. 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。 例句：The problem is when we can get a pay rise. 问题是，当我们可以得到加薪。 B. 连接表语从句的连接词有：that, what, who, when, where, which, why。例句： He has become what he wanted to be ten years ago. 他已经成为了他10年前想成为的。 She has remained where I stood yesterday for an hour. 她一直在我昨天站的地方站了一个小时。 His suggestion is that we should stay calm. 他的建议是，我们应该保持冷静。 The question is when he can arrive at the hotel. 问题是，他什么时候可以到达酒店。 二、注意： A. 表语从句一定要用陈述语序。 False: The question is when can he arrive at the hotel. Right: The question is when he can arrive at the hotel. B. 不可以用if，而用whether连接表语从句（as if 例外）； 引导宾语从句时可以互换if/whether，位于介词后要用whether； 位于句首时要用whether； 引导表语从句，主语从句，同位语从句时要用whether。 False: The question is if the enemy is marching towards us. Right: The question is whether the enemy is marching towards us. Right: It looked as if he had understood this question. C. 不像宾语从句，在有表语从句的复合句中，主句时态和从句时态可以不一致。 Right: The question is who will travel with me to Beijing tomorrow. Right: The question is why he cried yesterday. D. that在表语从句中不可以省掉。
表语从句讲解及练习
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)我想问的是谁离开了。My question is who left. 连接副词where, when, how, why。 What I wonder is when he left. 我想知道他是何时离开的。 This is where they once lived. 这就是他们曾经住过的地方。 That is why he didn't come here. The question is how he did it. (11)连词because可引导表语从句。如： (12)I think it is because you are doing too much. 我想这是因为你做得太多。 It's just because he doesn't know her. (13)T hat's because he didn't understand me. 那是因为他没有理解我.(That's because...强调原因) (14)T hat's why he got angry with me.那正是他对我生气的原因。(That's why...强调结果) (15)在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如： (16)M y suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。
主语从句和表语从句
主语从句和表语从句 知识点 1.名词性从句引导词的选择 选择原则“缺什么，补什么，什么不缺，用that” “什么不缺，用that”的意思是：如果从句中不缺任何成分，而且句意完整时，就用that来引导主语从句或表语从句以及其他的名词性从句。 2.whether 意为“是否”，引导的主语从句放在句首，不能用if 代替；但当用 it 作形式主语时，whether引导的主语从句放在句中或句末，此时可换用if. It is doubtful whether there’ll be any seats left.说不上是否还有座位了。 3.that 引导主语从句时，只起连接作用，不作任何成分，没有实际意义。在句 首时不可省略。What引导主语从句时既要起连接作用，又要在从句中作主语或宾语，在任何情况下都不能省略，它具有具体意义，表示“什么，所…… 的（事、物、话）”，相当于all that/ everything that. Which引导主语从句也作成分，它表示选择的意义，常译为“那个”。如：That he survived in the earthquake is a miracle. 他在地震中幸免于难，这是个奇迹。 4.关系代词what, which, who引导主语、表语从句时含有疑问意义，而whatever, whichever, whoever在引导名词性从句时，往往比what, which, who更强调，不表示疑问意义。而且whatever=all that/everything that; whichever=anything that; whoever=anyone who.另外，whatever=no matter what时引导状语从句。如：Whatever is worth doing at all is worth doing well.凡是值得做的事情都值得好好地做。 I语法填空。使用正确连接词补全下列句子。 1.They lost their way in the forest and ______made matters worse was ______ night began to fall. 2.______ drives after drinking should be punished. 3.It is said ______ Peter will have a chance to travel abroad next month. 4.______ we fear when traveling in summer is the sudden change of weather. 5.______ we will go camping tomorrow is up to you. 6.I read about it in some book or other, does it matter ______ it was? 7.______ of you comes in will be given a prize.

各类从句讲解与例句
英语中六大从句用法总结 1.主语从句 1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有： *It is a fact\a pity\a question\good news that... *It seems\appears\happened\has turned out that... *It is clear\important\likely\possible that... *It is said\reported\estimated\has been proved that... It is said that comic books create a connection between people of the same generation. It seems that the performance is very useful. 2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。 What we lack is experience. 3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。 How the plan is to be carried out should be discussed again. I did know why I felt like crying. 2.宾语从句 1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。 *I promised that I would change the situation. *All this is different from what American young people would say about friendship. *He is certain that watching so much television is not good for children. *This article is well-written except that it is a bit too long. 2）非谓语动词之后的宾语从句 Reading that it was just a difference in custom, the foreigner smiled and said nothing. 这个外国人知道了这只是风俗的不同后，就笑了笑，没说什么。 On being asked whether he had any good food in Germany, he answered ”Terrible”. 一问到他在德国是否吃过什么好菜，他就回答说：“糟糕的很”。 3)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。 He has made it clear that he would not change his mind. 4)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。 He didn't think that the money was well spent. 3.表语从句 表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how 等引导外，还可由because,as if(though)等引导。不缺其他成分时，用that引导，且不可省略。如主句主语为reason,只能用that引导表语从句，不可用because. Perhaps the most important thing to remember is that there is no one common type of life in America. The reason why so many people died there is that there were not enough food supplies. It looks as if successful international cultural communication will make the world smaller. 4.同位语从句 同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用whether,who,when,where,what,why,how等引导。常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。 She finally made the decision that she would join the fashion show.

(That’s because...强调原因) 那是因为他不理解我。 That’s why he got angry with me. (That’s why...强调结果) 那正是他对我生气的原因。 (2)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。 What cost him his life was that he was too careless. 使他丧命的原因是他太粗心了。 The reason why I was sad/for my being sad was that he didn’t understand me. 我难过的原因是他不理解我。 (3)使用虚拟语气的表语从句 在表示建议、劝告、命令含义的名词后的表语从句中，谓语动词需用“should＋动词原形”表示，should可省略。常见的词有：advice，suggestion，order，proposal，plan，idea，request，requirement等。 My suggestion is that we (should) have a discussion about this matter instead of just laying it aside. 我的建议是我们应当讨论一下这个问题，而不应该把它放在一边。 （4）as if/as though引导的表语从句常置于系动词look，seem，sound，be，become等后面，常用虚拟语气，即形式常用过去式的某种时态。
