表语从句重点详解
表语从句系动词的功能把表语（名词、形容词、某些副词、非谓词、介词短语、从句）和它的主语联系在一起，说明主语的属性、特征或状态。
它有自己的但不完全的词义，不能在句中独立作谓语，须和后面的表语一起构成句子的谓语。
系动词分类：一、根据系动词后所跟结构，我们可以把英语系动词分为两大类：完全系动词（其后只能跟表语的动词，如be, seem）和半系动词（其后既可跟表语作系动词用法，也可跟宾语或状语作实义动词用，如look）例如：1）He looked sadly at the boy.(“看着”，实义动词用法)He looks a clever boy .（“看起来”，系动词用法）2）He looks at a clever boy.（“看着”，实义动词用法）在英语中，某一动词是多义词，既有实义动词用法，又有系动词用法。
此类常见易混词有：change listen look touch①turn ②hear ③see ④become sound seem feeleat continue last remain⑤⑥⑦continue ⑧staytaste keep remain leave二、根据系动词的意义，我们把英语系动词分为四类：A．五大感官系动词B．状态系动词C．动态系动词D．双谓语系动词A．五大感官系动词，描述一种感官性质。
由实义感官动词变化而来，都是半系动词。
1．look“看起来像是”，后接adj.、n.、分词、介词短语、不定式等。
The girl bit her lips and looked thoughtful.这位女孩咬着嘴唇，看上去若有所思。
2．smell“闻起来”，后接adj.分词。
The flowers smell sweet. 这些花气味真香。
3．sound“听起来”，后接adj.\分词。
The music sounds sweet.这首诗听起来真悦耳。
4．taste“尝起来”，后接adj.\分词。

表语从句详解
表语从句详解一、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.可以接表语从句的系动词有：1.be（being,been,am,is,are,was,were)2. feel , seem , look, appear ,sound, taste , smell3. stand , lie , remain ,keep, stay4. become ,get , grow , turn ,go ,come, run, fall5. prove, turn outThe 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 was 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.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.例如：Go and get your coat. It's where you left it. 去把雨衣拿来.就在你原来放的地方.why I got wet t hrough. 我们既没伞也没雨衣，这是我们淋湿的原因.I had neither a raincoat nor an umbrella. That’sThat is how mice ruin many stores of grain every year.那就是老鼠是怎样每年损害大量粮食的.That is what he is worried about.那就是他所担心的.由连词because，as if/as though等引导的表语从句.It looked as if it was going to snow.看起来好像要下雪了.That's because we never thought of it.这是因为我们从未想过此事.好像他不知道答案.It seems as if he didn’t know the answer.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.基本用法表语从句只能置于主句之后，而主句的动词只能是联系动词.名词性从句在be等系动词后作表语时被称为表语从句例如：The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西. (how 在表语从句中充当方式状语)The scissors are not what I need. 这把剪刀不是我所需要的.(what 在表语从句中充当宾语)What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本.(what在主语从句中作直接宾语, that作为表语从句的引导词在该表语从句中不充当句子成分，不能省略)That is what I want to tell you.那就是我想要对你讲的.(what在表语从句中充当直接宾语)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)What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本.(what在主语从句中作直接宾语, that作为表语从句的引导词在该表语从句中不充当句子成分, 不能省略)That is what I want to tell you.那就是我想要对你讲的.(what在表语从句中充当直接宾语)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)注意That is why...是常用句型, 意为这就是,,的原因/因此,,, 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, 又如：That is why you see this old woman before you know, Jeanne. 珍妮, 这就是现在这个老太婆出现在你面前的原因.(前文提到Jeanne对老妇人显得苍老憔悴深感诧异, 说话人对她讲述了其中的原因之后，用这一句来进行概括).That is why I came. 这就是我来的原因.下面是两个与That is why...形式相似的结构, 它们与That is why...结构之间的关系要能够辨析清楚：(1)That is why...与That is the reason why...同义, 只不过从语法结构上讲, That is the reason why...中why引导的是—个定语从句, 将其中的the reason去掉则与That is why...结构一样, 例如：That is (the reason) why I cannot agree. 这就是我不能同意的理由.(2)That is because...句型中从属连词because引导的名词性从句在此作表语, 这也是个常用句型, 意为这就是为什么,,/因为,,.That is because...与That is why...之间的不同在于That is because...指原因或理由, That is why...则指由于各种原因所造成的后果, 例如：He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去看电影, 那是因为他得帮助他的妹妹做作业.(第一句话说明结果, 第二句话说明原因)He had seen the film before. That is why he did not see it last night.他以前曾看过那部电影, 因此他昨天晚上没有去看.(第一句话说明原因, 第二句话说明结果)表语从句与宾语从句的关系宾语从句和表语从句都属于名词性从句.其作用跟名词在句中的作用相同.故充当宾语的句子叫宾语从句，充当表语的句子叫表语从句.宾语从句(1)对于宾语从句要掌握以下三点①语序: 从句的语序必须是陈述句语序, 即主语 + 谓语这种形式.②时态: 当主句是一般现在时或一般将来时的时候, 从句可以是任何时态, 而当主句是一般过去时的时候, 从句, 从句时态必须是过去时范围的时态, 即(一般过去时, 过去进行时, 过去完成时, 过去将来时).③连接词: 当从句意思完整, 主句意思肯定时, 连接词用that, 且可以省去, 当从句意思完整, 主句意思不确定或含否定含意时, 常用if或whether(是否), 当从句意思不完整时, 连接词则是代替不完整部分的特殊疑问词.表语从句在句子中起表语作用的从句叫做表语从句，位于主句系动词的后面.表语从句的引导词和主语从句的引导词相同.也是名词性从句的一种.如： What the police want to know is when you entered red the room警察想知道的是你什么时候进的房间.The trouble is that we are short of funds困难是我们缺乏资金. This is what we should do这是我们应当做的.注意：从句中的疑问句用正常语序，即陈述语序. as if, as though, because也可用来引导表语从句.She seems as if she had done a great thing她看起来好像做了一件大事.It is because you eat too much是因为你吃得太多了. 单项选择1.

表语从句讲解
表语从句讲解一、什么是表语从句？表语从句放在连系动词之后，充当复合句中的表语。
表语从句(Predicative Clause)就是指一个句子作为表语，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。
二、表语从句的构成：关联词+简单句三、引导表语从句关联词种类：1. 可接表语从句的连系动词有be，look，seem，sound，appear等。
例句：At that time，it seemed as if I couldn't think of the right word. 当时，我似乎怎么也想不出一个恰当的字眼来。
2. 从属连词whether，as，as if / though引导的表语从句。
例句：It sounds as if someone is knocking at the door.听起来好像有人在敲门。
3. because，why引导的表语从句。
例句：That'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)注意：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。
4. 连接代词who，whom，whose，what，which，whoever，whatever，whichever连接副词 where，when，how，why例句：The problem is who we can get to replace her.问题是我们能找到谁去替换她呢。
5. 从属连词that例句：The trouble is that I have lost his address.麻烦是我把他的地址丢了。
6. 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，谓语动词需用“should+动词原形” 表示，should可省略。
表语从句讲解
表语从句1.定义:用作表语的从句叫做表语从句。
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定义:主语连系动词一个句子作表语---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。
造句:原因是他上学迟到了The reason was that he was late for school.(2)从属连词whether, as, as if。
如:1. He looked just as he had looked ten years before. 他看起来还与十年前一样。
2. The question is whether they will be able to help us.问题是他们是否能帮我们。
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: All this was over twenty years ago, but it’s as if it was only yesterday.这都是20多年前的事了,但宛如昨天一样。
造句:1. 关键是我们是否能解决问题。
The key is whether we can solve the problem.2. 看起来好像要下雨。
It looked as if it was going to rain.注:能跟表语从句的谓语动词一般为系动词be, seem, look,sound等。
如:He looked just as he had looked ten years before. 他看起来还与十年前一样。
造句:听起来好像有人在敲门。
It sounds as if someone is knocking at the door.(3)连接代词who, whom, whose, what, which, whoever, whatever, whichever 在表语从句中做主语、宾语等。
初中英语表语从句的详细讲解
初中英语表语从句的详细讲解在初中英语的学习中，表语从句是一个重要的语法点。
理解和掌握表语从句对于提升英语语言能力有着关键的作用。
接下来，让我们一起深入探究表语从句的奥秘。
一、什么是表语从句表语从句就是在复合句中充当表语的从句。
那什么是表语呢？表语是用来说明主语的身份、性质、品性、特征和状态的成分。
放在系动词之后。
常见的系动词有 be（am/is/are/was/were），seem，look，sound，feel，taste，smell 等等。
例如：“The problem is when we can finish the work” （问题是我们什么时候能完成这项工作。
）在这个句子中，“when we can finish the work”就是一个表语从句，在句中作表语，说明“the problem”的具体内容。
二、表语从句的引导词表语从句通常由以下这些词来引导：1、 thatthat 在表语从句中不充当任何成分，没有实际意义，只起连接作用。
例如：“The fact is that he is very talented” （事实是他非常有才华。
）2、 whetherwhether 表示“是否”，在表语从句中不充当成分。
例如：“The question is whether he will come” （问题是他是否会来。
）3、 what，who，whom，whose，which这些词在表语从句中充当主语、宾语、定语等成分，有具体的意义。
例如：“This is what I want” （这就是我想要的。
）这里“what”作“want”的宾语。
4、 when，where，why，how这些词在表语从句中充当状语，表示时间、地点、原因、方式等。
例如：“That's why I was late” （那就是我迟到的原因。
）“why”在从句中作原因状语。
三、表语从句的位置表语从句通常位于系动词之后，常见的结构是“主语＋系动词＋表语从句”。
英语语法考点归纳之表语从句讲解
使用虚拟语气的表语从句用于条件状语从句中
• 表语从句通常用正常语序，而使用虚拟语气的表语从句通常用于 条件状语从句中。同时，在条件状语从句中使用虚拟语气时，主 从句的动词形式需要保持一致。这些规则在句子中得到了强调。
在条件状语从句中使用虚拟语气时，主从句的动词形式需要保持一致
01
表语从句易错点
02
主语连词表语的结构
这种结构中，连 词在主语和表语 之间起到连接的 作用。常用的连 词有。
“The problem is who can do the job.”（问题 是谁能做这个工 作。）。
that，whether ，as，as if / though等。例如 。
whether主语表语或not的结构
kindly helped me”则不正确。
在条件状语从句中使用虚拟语气时，主从句的动词形式需要保 持一致
时态错误
使用正确时态很重要，否则 影响句意
例如：正确的句子应该是“He is a kind man” （他是一个和蔼的人），而不是“He is a
kindly man”（他是一个友善的人）。同时， “He is very kind”也是正确的表达方式，而 “He very kindly helped me”则不正确。
whether的用法
whet连词的作用。例如。“The question whether he will come is still undecided.”（他是否会来这个问题还没有决定。 ）。not是否定的意思，可以引导表语从句表示否定。例如。

表语从句详解
表语从句详解一、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.可以接表语从句的系动词有：1.be（being,been,am,is,are,was,were)2. feel , seem , look, appear ,sound, taste , smell3. stand , lie , remain ,keep, stay4. become ,get , grow , turn ,go ,come, run, fall5. prove, turn outXXX 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 XXX XXX.这就是为何在新英格兰用石头墙而不消栅栏的缘故原由.At that time, it seemed as if I couldn't think of the right word anyhow.其时,我好像如何也想不出一个得当的字眼来.指导表语从句的词：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；干系副词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.XXX 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 XXX.问题是它作为日常之用太贵重了.XXX.我们不能理解越来越少的学生对他的课不感兴趣.由干系代词指导的表语从句.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 XXX.那就是他在忧郁的事.That's what we should do.那是我们该当作的.由关系副词引导的表语从句.干系副词when, where, how, why除在句子起毗连感化外，在从句中还充其工夫，地址，体式格局或缘故原由状语，本人具有词义.比方：Go and get your coat. It'swhere you left it.去把雨衣拿来.就在你原先放的中央.I had XXX’swhy I got XXX.我们既没伞也没雨衣，这是我们淋湿的原因.That XXX.那就是老鼠是怎样每年损害大量粮食的.That is what he is XXX.那就是他所忧郁的.由连词because，as if/as though等引导的表语从句.It looked as if it was going to snow.看起来仿佛要下雪了.That's because we never thought of it.这是因为我们从未想过此事.It seems as if he didn’t know XXX.好像他不知道答案.注意A.表语从句一定要用陈述语序.False: XXX is when can he arrive at the hotel.Right: The question is when he can arrive at the XXX不成以用if，而用whether毗连表语从句(as if破例）.指导宾语从句时可以交换if/whether位于介词后要用whether位于句首时要用whether.指导表语从句，主语从句，同位语从句时要用whether.False: XXX.Right: XXX.Right: It looked as if he had XXX.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: XXX is who will travel with me to Beijing tomorrow.Right: XXX is why he cried XXX.D. that在表语从句中不可以省掉.基本用法表语从句只能置于主句以后，而主句的动词只能是接洽动词.名词性从句在be等系动词后作表语时被称为表语从句比方：The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西. (how在表语从句中充当方式状语)The scissors are not what I need.这把剪刀不是我所需要的.(what在表语从句中充当宾语)What I told him was that I would find him a good play.我告诉他的是我会给他找个好剧本.(what在主语从句中作直接宾语,that作为表语从句的引导词在该表语从句中不充当句子成分，不能省略)That is what I want to tell you.那就是我想要对你讲的.(what 在表语从句中充当直接宾语)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)What I told him was that I would find him a good play.我告诉他的是我会给他找个好剧本.(what在主语从句中作直接宾语,that作为表语从句的引导词在该表语从句中不充当句子成分,不能省略)That is what I want to tell you.那就是我想要对你讲的.(what 在表语从句中充当直接宾语)That is why she failed to pass the exam.那就是她测验不合格的缘故原由.(why在表语从句中充任缘故原由状语)留意That is why...是经常使用句型,意为这就是……的缘故原由/因而……,个中why指导的名词性从句在句中作表语,该句型通经常使用于针对前面曾经申明过的缘故原由举行总结,又如：That is why you see this old woman before you know, XXX.XXX,这就是目前这个老太婆出目前你眼前的缘故原由.(前文提到XXX对老太婆显得衰老枯槁深感惊奇,语言人对她报告了个中的缘故原由以后，用这一句来举行归纳综合).That is why I came.这就是我来的缘故原由.上面是两个与That is why...方式类似的布局,它们与That is why...布局之间的干系要可以辨析分明：(1)That is why...与That is the reason why...同义,只不外从语法布局上讲,That is the reason why...中why指导的是—个定语从句,将个中的the reason去掉则与That is why...布局一样,比方：That is (the reason) why I cannot agree.这就是我不克不及赞成的来由.(2)That is because...句型中附属连词because指导的名词性从句在此作表语,这也是个经常使用句型,意为这就是为何……/因为…….That is because...与That is why...之间的分歧在于That is because...指缘故原由或来由,That is why...则指因为各类缘故原由所形成的结果,比方：He did not see the film last night. That is because he had to help his little sister with her XXX昨天晚上他没有去看电影,那是因为他得帮助他的妹妹做作业.(第一句话说明结果,第二句话说明原因)He had seen the film before. That is why he did not see it last night.他从前曾看过那部片子,因而他今天早晨没有去看.(第一句话申明缘故原由,第二句话申明成效)表语从句与宾语从句的关系宾语从句和表语从句都属于名词性从句.其作用跟名词在句中的作用相同.故充当宾语的句子叫宾语从句，充当表语的句子叫表语从句.宾语从句(1)对于宾语从句要掌握以下三点①语序:从句的语序必需是XXX说句语序,即主语+谓语这类方式.②时态:当主句是一般现在时或一般将来时的时候,从句可以是任何时态,而当主句是一般过去时的时候,从句,从句时态必须是过去时范围的时态,即(一般过去时,过去进行时,过去完成时,过去将来时).③毗连词:当从句意义完整,主句意义一按时,毗连词用that,且可以省去,当从句意义完整,主句意义不肯定或含否认含义时,经常使用if或whether(是不是),当从句意义不完整时,毗连词则是替代不完整局部的非凡疑问词.表语从句在句子中起表语感化的从句叫做表语从句，位于主句系动词的背面.表语从句的指导词和主语从句的指导词不异.也是名词性从句的一种.如：What the police want to know is when you entered red the room警察想知道的是你什么时候进的房间.The trouble is that we are short of funds困难是我们缺乏资金. This is what we should do这是我们应当做的.注意：从句中的疑问句用正常语序，即陈述语序. as if, as though, because也可用来引导表语从句.She seems as if she had done a great XXX她看起来好像做了一件大事.It is because you eat too much是因为你吃得太多了.单项选择1.

(完整版)表语从句详解
表语从句详解一、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.可以接表语从句的系动词有：1.be（being,been,am,is,are,was,were)2. feel , seem , look, appear ,sound, taste , smell3. stand , lie , remain ,keep, stay4. become ,get , grow , turn ,go ,come, run, fall5. prove, turn outThe 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 was 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.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.例如：Go and get your coat. It's where you left it. 去把雨衣拿来.就在你原来放的地方.I had neither a raincoat nor an umbrella. That’s why I got wet t hrough. 我们既没伞也没雨衣，这是我们淋湿的原因.That is how mice ruin many stores of grain every year.那就是老鼠是怎样每年损害大量粮食的.That is what he is worried about.那就是他所担心的.由连词because，as if/as though等引导的表语从句.It looked as if it was going to snow.看起来好像要下雪了.That's because we never thought of it.这是因为我们从未想过此事.It seems as if he didn’t know the answer.好像他不知道答案.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.基本用法表语从句只能置于主句之后，而主句的动词只能是联系动词.名词性从句在be等系动词后作表语时被称为表语从句例如：The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西. (how 在表语从句中充当方式状语)The scissors are not what I need. 这把剪刀不是我所需要的.(what 在表语从句中充当宾语)What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本.(what在主语从句中作直接宾语, that作为表语从句的引导词在该表语从句中不充当句子成分，不能省略)That is what I want to tell you.那就是我想要对你讲的.(what在表语从句中充当直接宾语)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)What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本.(what在主语从句中作直接宾语, that作为表语从句的引导词在该表语从句中不充当句子成分, 不能省略)That is what I want to tell you.那就是我想要对你讲的.(what在表语从句中充当直接宾语)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)注意That is why...是常用句型, 意为这就是……的原因/因此……, 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, 又如：That is why you see this old woman before you know, Jeanne. 珍妮, 这就是现在这个老太婆出现在你面前的原因.(前文提到Jeanne对老妇人显得苍老憔悴深感诧异, 说话人对她讲述了其中的原因之后，用这一句来进行概括).That is why I came. 这就是我来的原因.下面是两个与That is why...形式相似的结构, 它们与That is why...结构之间的关系要能够辨析清楚：(1)That is why...与That is the reason why...同义, 只不过从语法结构上讲, That is the reason why...中why引导的是—个定语从句, 将其中的the reason去掉则与That is why...结构一样, 例如：That is (the reason) why I cannot agree. 这就是我不能同意的理由.(2)That is because...句型中从属连词because引导的名词性从句在此作表语, 这也是个常用句型, 意为这就是为什么……/因为…….That is because...与That is why...之间的不同在于That is because...指原因或理由, That is why...则指由于各种原因所造成的后果, 例如：He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去看电影, 那是因为他得帮助他的妹妹做作业.(第一句话说明结果, 第二句话说明原因)He had seen the film before. That is why he did not see it last night.他以前曾看过那部电影, 因此他昨天晚上没有去看.(第一句话说明原因, 第二句话说明结果)表语从句与宾语从句的关系宾语从句和表语从句都属于名词性从句.其作用跟名词在句中的作用相同.故充当宾语的句子叫宾语从句，充当表语的句子叫表语从句.宾语从句(1)对于宾语从句要掌握以下三点①语序: 从句的语序必须是陈述句语序, 即主语 + 谓语这种形式.②时态: 当主句是一般现在时或一般将来时的时候, 从句可以是任何时态, 而当主句是一般过去时的时候, 从句, 从句时态必须是过去时范围的时态, 即(一般过去时, 过去进行时, 过去完成时, 过去将来时).③连接词: 当从句意思完整, 主句意思肯定时, 连接词用that, 且可以省去, 当从句意思完整, 主句意思不确定或含否定含意时, 常用if或whether(是否), 当从句意思不完整时, 连接词则是代替不完整部分的特殊疑问词.表语从句在句子中起表语作用的从句叫做表语从句，位于主句系动词的后面.表语从句的引导词和主语从句的引导词相同.也是名词性从句的一种.如： What the police want to know is when you entered red the room警察想知道的是你什么时候进的房间.The trouble is that we are short of funds困难是我们缺乏资金. This is what we should do这是我们应当做的.注意：从句中的疑问句用正常语序，即陈述语序. as if, as though, because也可用来引导表语从句.She seems as if she had done a great thing她看起来好像做了一件大事.It is because you eat too much是因为你吃得太多了.单项选择1.

表语从句语法讲解
表语从句语法讲解一、表语从句的组成表语从句是一种句子结构，它用来说明主语的性质、状态、特征、身份、关系等。
表语从句通常由两个部分组成：引导词和从句。
引导词是一个特殊的词，它用来引导表语从句。
从句则是一个完整的句子，它包含主语、谓语和宾语等成分。
二、表语从句的分类表语从句可以根据引导词的不同进行分类。
常见的引导词包括: 1. 疑问词：用来引导表语从句的疑问词有 who、whom、whose、what 和 which 等。
例如:- The man who I met yesterday is my teacher.(我昨天遇到的那个人是我的老师。
)- The book which you lent me is very interesting.(你借给我的那本书非常有趣。
)2. 副词：用来引导表语从句的副词有 how、when、where、why 和however 等。
例如:- She lives in a city where it is very hot in summer.(她住在一个夏天非常热的城市。
)- He always does his homework how his teacher tells him to.(他总是按照老师告诉他的方式做作业。
)3. 连接代词：用来引导表语从句的连接代词有 that、whether、if 和 whoever 等。
例如:- The weather is good, which makes me happy.(天气很好，这让我很开心。
)- I don"t know whether he will come or not.(我不知道他是否会来。
)三、表语从句的引导词和语序表语从句的引导词通常放在主语和从句之间，语序是主语 + 引导词 + 从句。
例如:- The man who I met yesterday is my teacher.(我昨天遇到的那个人是我的老师。
表语从句讲解
表语从句讲解表语从句是介绍主句主语性质、状态或者说明它们关系的从句，它与主句主语一起形成一个整体，表示一种概念，也可以被称为"定语从句"。
1、定义表语从句是一个定语性从句，它位于句首或句末，它们一般有以下几种结构：①、that从句：以主句为谓语，that引出的表语从句位于句末。
构成形式：主语+ be/助动词/情态动词+that从句。
如：He is known to everyone that he is an excellent scientist.大家都知道他是一位优秀的科学家。
②、to do从句：以主句为谓语，to do引出的表语从句位于句末。
构成形式：主语+ be/助动词/情态动词+to do 从句。
如：This is enough to prove to him that he is wrong.这足以证明他是错的。
③、wh-从句：以主句为谓语，wh-引出的表语从句位于句末。
构成形式：主语+ be/助动词/情态动词+wh-从句。
如：It is a great pleasure for us that what you said is true.你所说的是真的，这对我们来说是一个巨大的乐趣。
2、特点（1）表语从句句首时，that引导的引导词可省略，并且其前省略的主要是be动词；（2）表语从句句尾时，表示“做某事”的动词一般用不定式，表示“成为...”，“感觉到，想象”的动词一般用宾语从句；（3）表语从句的谓语动词的形式一般不受句子的时态影响。
3、作用（1）表语从句表示主语的性质、状态或内容。
如：The difficult situation was that John was absent from the meeting.困难的情况是约翰缺席会议。
（2）表语从句可用于强调句子主语。
如：This is not an ordinary book，that is quite clear.这不是一本普通的书，这很清楚。

表语从句详解一、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.可以接表语从句的系动词有：（being,been,am,is,are,was,were)2. feel , seem , look, appear ,sound, taste , smell3. stand , lie , remain ,keep, stay4. become ,get , grow , turn ,go ,come, run, fall5. prove, turn outThe 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 was 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.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.例如：Go and get your coat. It's where you leftit. 去把雨衣拿来.就在你原来放的地方.I had neither a raincoat nor an umbrella. That’s why I got wet throu gh. 我们既没伞也没雨衣，这是我们淋湿的原因.That is how mice ruin many stores of grain every year.那就是老鼠是怎样每年损害大量粮食的.That is what he is worried about.那就是他所担心的.由连词because，as if/as though等引导的表语从句.It looked as if it was going to snow.看起来好像要下雪了.That's because we never thought of it.这是因为我们从未想过此事.It seems as if he didn’t know the answer.好像他不知道答案.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.基本用法表语从句只能置于主句之后，而主句的动词只能是联系动词.名词性从句在be等系动词后作表语时被称为表语从句例如：The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西. (how 在表语从句中充当方式状语)The scissors are not what I need. 这把剪刀不是我所需要的.(what 在表语从句中充当宾语)What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本.(what在主语从句中作直接宾语, that作为表语从句的引导词在该表语从句中不充当句子成分，不能省略)That is what I want to tell you.那就是我想要对你讲的.(what在表语从句中充当直接宾语)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)What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本.(what在主语从句中作直接宾语, that作为表语从句的引导词在该表语从句中不充当句子成分, 不能省略)That is what I want to tell you.那就是我想要对你讲的.(what在表语从句中充当直接宾语)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)注意That is why...是常用句型, 意为这就是……的原因/因此……, 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, 又如：That is why you see this old woman before you know, Jeanne. 珍妮, 这就是现在这个老太婆出现在你面前的原因.(前文提到Jeanne对老妇人显得苍老憔悴深感诧异, 说话人对她讲述了其中的原因之后，用这一句来进行概括).That is why I came. 这就是我来的原因.下面是两个与That is why...形式相似的结构, 它们与That is why...结构之间的关系要能够辨析清楚：(1)That is why...与That is the reason why...同义, 只不过从语法结构上讲, That is the reason why...中why引导的是—个定语从句, 将其中的the reason 去掉则与That is why...结构一样, 例如：That is (the reason) why I cannot agree. 这就是我不能同意的理由.(2)That is because...句型中从属连词because引导的名词性从句在此作表语, 这也是个常用句型, 意为这就是为什么……/因为…….That is because...与That is why...之间的不同在于That is because...指原因或理由, That is why...则指由于各种原因所造成的后果, 例如：He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去看电影, 那是因为他得帮助他的妹妹做作业.(第一句话说明结果, 第二句话说明原因)He had seen the film before. That is why he did not see it las t night.他以前曾看过那部电影, 因此他昨天晚上没有去看.(第一句话说明原因, 第二句话说明结果)表语从句与宾语从句的关系宾语从句和表语从句都属于名词性从句.其作用跟名词在句中的作用相同.故充当宾语的句子叫宾语从句，充当表语的句子叫表语从句.宾语从句(1)对于宾语从句要掌握以下三点①语序: 从句的语序必须是陈述句语序, 即主语+ 谓语这种形式.②时态: 当主句是一般现在时或一般将来时的时候, 从句可以是任何时态, 而当主句是一般过去时的时候, 从句, 从句时态必须是过去时范围的时态, 即(一般过去时, 过去进行时, 过去完成时, 过去将来时).③连接词: 当从句意思完整, 主句意思肯定时, 连接词用that, 且可以省去, 当从句意思完整, 主句意思不确定或含否定含意时, 常用if或whether(是否), 当从句意思不完整时, 连接词则是代替不完整部分的特殊疑问词.表语从句在句子中起表语作用的从句叫做表语从句，位于主句系动词的后面.表语从句的引导词和主语从句的引导词相同.也是名词性从句的一种.如：What the police want to know is when you entered red the r oom警察想知道的是你什么时候进的房间.The trouble is that we are short of funds困难是我们缺乏资金. This is what we should do这是我们应当做的.注意：从句中的疑问句用正常语序，即陈述语序. as if, as though, because也可用来引导表语从句.She seems as if she had done a great thing她看起来好像做了一件大事.It is because you eat too much是因为你吃得太多了.单项选择1.
