2、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。

它位于主句中的系动词之后，对主语进行解释、说明或描述。
二、表语从句的引导词1、常用引导词that：在句中不充当任何成分，没有实际意义，通常不可省略。
whether：意为“是否”，在句中不充当任何成分。
as if ／ as though：意为“好像”，在句中不充当成分。
because：表示原因。

例如：The fact is that he is very talented （事实是他非常有才华。
）我记得有一次，我在课堂上讲解这个知识点的时候，一个学生突然举手说：“老师，这个 that 感觉没啥用啊，为什么不能省略呢？”我笑着回答他：“这就好比一辆车的螺丝钉，虽然看起来小，也不显眼，但少了它可不行。
that 在这里虽然不充当成分，可它起着连接主句和从句的重要作用，缺了它，句子就不完整啦。

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。

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。

The problem is (that) we don't have enough time to finish the project.（问题是我们没有足 够的时间来完成这个项目。）
从句中的语序问题
• 在表语从句中，语序也是一个需要注意的问题。一般来说， 表语从句应该遵循陈述句的语序，即主语、谓语、宾语的顺 序。例如，“The reason was that he had an accident.” 这个句子中，从句“that he had an accident”遵循了陈 述句的语序，使得句子更加易于理解。同时，在某些情况下 ，也可以使用倒装语序，但需要注意不要违反语法规则。

(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.

总结表语从句知识点一、表语从句的定义和特点表语从句是一个从句，它在句子中作表语，用来说明主语、宾语的性质、特征、身份、状态、观念和判断等。
表语从句不可以独立存在，它必须与主句连成一个完整的句子。
表语从句有以下几个特点：1. 它可以由连接代词或连接副词“that, whether, if, who, whom, which, whose, what, when, where, why, how, as, as if, as though, so that” 等引导；2. 当主句为一般过去时，表语从句中的谓语动词要用过去时态；3. 表语从句通常紧跟在连系动词后面；4. 表语从句中的谓语动词常常是系动词；5. 在口语中，表语从句中的连词that 可以省略，但在正式的书面语中一般不省略。
二、表语从句的引导词表语从句可以由连接代词或连接副词引导。
下面是各种连接代词和连接副词的用法和区别：1. 连接代词的用法1) that(1) 作宾语从句或表语从句的引导词，引导主语、宾语的宾语从句或表语从句。
(2) 只能引导宾语从句或表语从句，不能引导状语从句。
(3) 在口语中常被省略，但在有时候不得不用，以免误解。

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 through. 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.
