名词性从句学案语法精讲主语从句宾语从句表语从句同位语从句经典习题含答案
名词性从句名词性从句（主语、表语、宾语、同位语从句）
（一）主语从句
1．定义：用作主语的从句叫做主语从句。
2．2．构成：关联词+简单句
3．3．引导主语从句的关联词有三类：
4．(1) 从属连词that。如：
That they were in truth sisters was clear from the facial resemblance between them. 很明显，她们确是亲姐妹，她们的脸型很相似。
(2) 从属连词whether。如：
Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。
(3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever
连接副词 where, when, how, why。如：
What she did is not yet known. 她干了什么尚不清楚。
解释：
1．主语从句能用it作形式上的主语。常以it作形式主语的句型有：
A. 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：
(1) 从属连词that。如：
The trouble is that I have lost his address. 麻烦是我把他的地址丢了。
(2) 从属连词whether, as, as if。如：
He looked just as he had looked ten years before. 他看起来还与十年前一样。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
能跟表语从句的谓语动词一般为系动词be, seem, look等。如：
It looked as if it was going to rain. 看起来天要下雨了。
(3)连接代词who, whom, whose, what, which, whoever, whatever, whichever
连接副词 where, when, how, why。
如： The question is how he did it. 问题是他是如何做此事的。
解释：
1．连词because可引导表语从句。如：
I think it is because you are doing too much. 我想这是因为你做得太多。2．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：
My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。
注意：
1．what引导
●“…….+ is = “…….+ is .….
是表语从句”
例：Raw material is what we are badly in need of.
= Raw material is the thing that we are badly in need of.
2．when、where、why、whether、how引导
●“…….+ is +when、where、why、whether、how表语从句”，表示“.….是表语从
句”
例：That’s where we differ.
●表语从句中只能用whether表示是否
例：The question is whether we can finish our work by tomorrow morning. 3．that引导
●“…….+ is /remain/look/seem/appear + that表语从句”，表示“.….是表语从
句”
例：What’s troubling me is that I don’t have much experience in this field.
●主语是reason时，表语从句必须由that引出
例：The reason I don’t go there was that I got a new job.
4．as if/as through引导
●“……look/seem/appear/remain（系动词）+ as if/as through 表语从句”，表
示“.….好像表语从句”例：It looks as if it is going to rain.
（三）宾语从句
1．定义：用作宾语的从句叫宾语从句。
2．构成：关联词+简单句
3．引导宾语从句的关联词有三类：
(1) 从属连词that。如：
He told us that he felt ill. 他对我们说他感到不舒服。
注： that在引导宾语从句时也并不是任何情况下都可以省略。在以下情况下，that不能省略。
1． Everybody could see what happened and that Tom was frightened.(and连接两个宾语从句，that宾语从句放在and的后面时，that不能省略。)大家都会看出发生的事情并知道Tom非常害怕。
2．I know nothing about him except that he is from the south.(that引导的宾语从句作介词宾语时，that不能省略。)
对他我一无所知，只知道他是南方人。
3．That he ever said such a thing I simply don’t believe. (that从句位于句首时，that不可省略。)
我简直不相信他曾说过这样的话。
4． We decided, in view of his special circumstances, that we would admit him for a probationary period. (主句谓语动词与that从句之间有插入语，that不可省略。)
鉴于他的特殊情况，我们决定应允他一段试用期。
(2)从属连词if/whether。如：
I doubt whether he will succeed. 我怀疑他是否会成功。
(3)连接代词who, whom, whose, what, which, whoever, whatever, whichever
连接副词 where, when, how, why。
如：Who or what he was, Martin never learned.
(1) 介词宾语从句
宾语从句也可用作介词的宾语。如：
He was deeply displeased by what had occurred that day.
他对那天发生的事感到很不快。
I walked over to where she sat. 我走向她坐的地方。
有时介词可以省略。如：
I don’t care (for) who marries him. 我不管谁跟他结婚。解释：1．如果宾语从句后还有宾语补足语，则用it作形式宾语，而将宾语从句后置。如：
We thought it strange that Xiao Wang did not come yesterday.
我们认为小王昨天没来是奇怪的。
He has made it clear that he will not give in.
他已表明他不会屈服。
2．作介词的宾语：连词that引导的名词性从句很少作介词的宾语，只用在except, but, in
后。其他一些介词的宾语从句如果由连词that引导，则需用it先行一步，作形式宾语。如：He is a good student except that he is careless.
他是一个好学生，只是有点粗心。
You may rely on it that I shall help you. 你可以指望我会帮助你的。
介词宾语不可以用which来引导，而要用what来引导。如：
Are you sorry for what you've done?
你为你所做的一切感到内疚吗？
3．某些形容词或过去分词后常接宾语从句，这类形容词或过去分词有sure, glad, certain, pleased, happy, afraid, surprised, satisfied等，连词that可省略。如：
I am not sure what I ought to do.
我不能确定我该做什么。
4．连词whether (…or not)或if引导的宾语从句
if和whether引导的宾语从句可以互换使用，但whether常和or not连用，if一般不与or not连用。如：
I wonder whether it is true or not. 我不知它是真是假。
5．宾语从句的否定转移。在think, believe, suppose, expect等动词后的宾语从句，有时谓语尽管是否定意思，却不用否定形式，而将think等动词变为否定形式。如：
I don’t think you are right. 我认为你错了。
6．宾语从句的时态变化规律：
(1) 当主句是一般现在时态时，从句可根据需要用任何时态。
(2) 当主句是一般过去时态时，从句只能使用过去范围内的任何时态。但客观真理除外。如：The teacher said that the earth goes round the sun.
老师说地球绕着太阳运行。
注意：that引导
●“主语 + 谓语动词 + that宾语从句”，表示“…..做（动作）宾语从句”
例：The pupils said (that) the questions were too difficult.
●that可省略
●“Sb.don’t doubt（否定/疑问句） + that宾语从句”：否定怀疑时，必须用that
例：I don’t doubt that he is telling the truth.
●“discuss + that 宾语从句”：discuss后面必须跟that 引导的宾语从句
例：We discussed that we should put off the meeting.
●若that引导的宾语从句还有补足语的话，需引入形式并与it，即“动词 + it + 宾
语补足语 + that宾语从句”
例：Clinton wants to make it clear to the public that the government will investigate the event seriously.
（四）同位语从句
1．定义：用作同位语的从句叫做同位语从句。
2．用法：同位语从句的先行词多为fact, news, idea, thought, question, reply, report,
remark等，关联词多用从属连词that。如：
They were all very much worried over the fact that you were sick.
对你生病这件事，他们都很焦虑。
注：同位语从句偶尔由从属连词whether引导。如：
I have no idea whether he’ll come or not. 我不知道他是否来。
连接代词who, which, what和连接副词where, when, why, how亦可引导同位语从句。
The question who should do the work requires consideration.
谁该干这项工作，这个问题需要考虑。
We haven't yet settled the question where we are going to spend our summer vacation. 到哪儿去度暑假，这个问题我们还没有决定。
It is a question how he did it.
那是一个他如何做了此事的问题。
解释：
1．that引导的同位语从句与定语从句之区别
that引导的同位语从句，that引导的定语从句
功能上：that只起连接从句的作用，无意义。在从句中不充当句子成分。不可省。
that替代先行词在从句中不仅起连接作用，还充当一个句子成分。如在从句中作动词的宾语时可省略。
意义上：从句是被修饰名词的内容。从句起限定作用，是定语
如：The news that Mr. Li will be our new English teacher is true. (同位语从句，that 不可省。)
李先生将是我们的新英语老师这个消息是真的。
2．一些表示“建议、命令、要求”的名词后所跟的同位语从句中，谓语动词用虚拟语气should+动词原形表示。should可省。如：
This is our only request that this (should) be settled as soon as possible.
这就是我们唯一的请求：尽快解决这个问题。
注意：that引导
●“fact/fear/news/message/word/story/question/problem/truth/hope/idea/pro
mise/ suggestion/belief/doubt/evidence（抽象名词） + that同位语从句 + 谓
语 + 其他”
例：The news that he intended to come gave us much pleasure.
●若同位语从句较长，可将位于主句的谓语动词提前，将同位语从句置后
例：Evidence came up that specific speech sounds are recognized by babies as young as 6 months old.

主语从句 & 表语从句
主语从句& 表语从句 【观察】观察下列句子中从句的用法，然后加以总结。 1. What we need is more time while what they need are more people. 2. It was not known whether/if he would come to the party. 3. Whether we will go fishing tomorrow depends on the weather. 4. Do you think it is necessary that we (should) have all the chairs replaced? 5. It is suggested that you (should) attend the opening ceremony. 6. The question remains whether they will be able to help us. 7. My suggestion is (that) you (should) discuss your problems with your parents first. 8. The reason why I was late this morning is that I missed the early bus. 9. He was very busy. That was why he didn’t come here. 10. Tom looked sad. That’s because he didn’t pass the exam. 11. The house smells as if it hasn’t been lived in for ye ars. 12. Dressed in red, she looks as if she were ten years younger. 13. Has it been decided when we’ll have the final examination? 【总结】 主语从句和表语从句都属于名词性从句。主语从句在复合句中作主语，表语从句在复合句中作表语。在具体的应用中要掌握以下几点： ● 引导词(详见P138-139, B7) 注意易错引导词： (1) 引导主语从句位于句首时只能用whether (如例句3)，句中可用if (如例句2)，引导表语从句只能用whether (如例句6)； (2) 主句的主语是reason时，表语从句要用that，不能用because引导(如例句8)； (3) 引导表语从句时，why强调结果(如例句9)，because强调原因(如例句10)； (4) that只起连接作用，不在从句中作成分，无词义。引导主语从句时不能省略，引导表语从句时可以省略。 ● it作形式主语 有时为避免句子头重脚轻，常用it代替主语从句作形式主语放于句首，而把主语从句置于句末。主句的谓语动词一般用单数形式： (1) 常用句型：It+be+名词词组/形容词/过去分词+ that从句(如例句4-5)； (2) 在由连词wh-引导的主语从句中，从句可放在句首，也可用it作形式主语而把从句放在句末(如例句2、 13)。 ● 语序：主语从句和表语从句必须用陈述语序。 ● 主谓一致 主语从句作主语时谓语动词用单数形式。what引导主语从句，主句的谓语动词多用单数形式，但若表语是复数时，谓语动词用复数形式(如例句1)。 ● 语气

※※※ 主语从句： 1. What he needs is the shirt of a happy person to wear. 2. What his father said made him think carefully. 3.

That’s because he was a really good student. 5. Another popular idea is that Stonehenge might be a kind of calendar. 6. Other advantages of bike riding are that it’s good for health. 7. One of the greatest mysteries is how it was built because the stones are so big and heavy.
8. That’s how people in Japan are expected to greet each other. 9. That’s when I decided to change. 关键部位已标蓝： ※※※ 主语从句： 1. What he needs is the shirt of a happy person to wear. 2.

从句归纳区分定语从句、宾语从句、同位语从句
从句小结 从句总述： 从句有主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句6类。 由于主语从句、表语从句、宾语从句及同位语从句在句子的功用相当于名词，故而这4种从句又通称名词性从句。 1.主语从句（Subject Clause）：用作主语的从句叫主语从句。引导主语从句的关联词有从属连词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等。 2.表语从句（Predicative Clause）：用作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大都一样。 3.宾语从句（Object Clause）：在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句. 4. 同位语从句（Appositive Clause）：在复合句中用作同位语的从句叫同位语从句。它一般跟在某些名词后面，用以说明该名词表示的具体内容。其关联词多为that。 状语从句还可以分为条件状语从句、原因状语从句、方位状语从句和时间状语从句等。 宾语从句 学习宾语从句要抓住三要素：时态、语序、连接词。 一：时态和语序 1·主句用一般现在时，从句可用任意时态。 2·主句用过去时，从句用过去某个时态。 3·主句用过去时，从句是真理时，只用一般现在时。 语序：宾语从句只能用陈述句语序，坚决不能用疑问句语序。 二：连接词 ①从属连词 连接宾语从句的从属连词主要有that，if，whether. that引导表示陈述句的宾语从句,而if和whether引导表示“是否”的宾语从句. 例句： He told that he would go to the college the next year 他告诉我他下一年上大学. I don’t know if there will be a bus any more. 我不知道是否还会有公交车. ②连接代词 连接代词主要有who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever等. 连接代词一般指疑问,但what, whatever除了指疑问外,也可以指陈述. 例句： Do you know who has won Red Alert game 你知道谁赢了这一局红警游戏吗 ③连接副词 连接副词主要有when,where,why,how,whenever,wherever,however等. 例句： He didn’t tell me when we should meet again. 他没有告诉我什么时候我们能再见面.

【本讲教育信息】 一. 教学内容： 名词性从句——宾语从句与表语从句 二. 知识精讲 在复合句中起名词性作用的句子叫名词性从句。名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，根据它在句中不同的语法功能，因此名词从句又分为主语从句、宾语从句、表语从句和同位语从句。 （一）宾语从句 1. 概念及引导词 在复合句中起宾语作用的从句叫宾语从句。引导宾语从句的连接词有连接代词（who, whom, whose , what , which, whoever , whatever, whichever ）、连接副词(when , where , how, why )及从属连词(that , whether, if ). 例：John said （that）he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。 I am glad that you are satisfied with your job. 你对工作满意我感到很高兴。 She will name him whatever she wants to. 她高兴给他起什么名字就起什么名字。 That depends on where we shall go. 那取决于我们去哪儿。 2. 宾语从句的种类 常见的宾语从句有动词的宾语从句、介词的宾语从句和形容词的宾语从句三种。 （1）动词的宾语从句 They know that the habit may kill them.定语从句 他们知道这个习惯会害死他们。 They doubt whether or not Jack is a good student. 他们怀疑Jack是否是一个好学生。 They wanted to see which shops offered the best advice and service定语从句. 他们想了解哪家店提出的建议和提供的服务最好。 （2）介词的宾语从句 一般情况下介词后只能接wh- 类连接词引导的宾语从句，但but, except, besides等后可接that引导的宾语从句。 We are talking about what we’ll do next. 我们正在讨论下一步做什么。 I know nothing about him except that he lives here. 对于他，我只知道他住在这儿，其他一无所知。
主语从句详解及练习-附答案
语法要点剖析 一、名词性从句 主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。 引导名词性从句的连接词可分为三类： 连接词：that, whether, if （不充当从句的任何成分） 连接代词：what, whatever, who, whoever, whom, whose, which. 连接副词：when, where, how, why 1. 主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if 和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用；连接代词和连接副 词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如： What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 It is known to us how he became a writer. 我们都知道他是如何成为一名 作家的。 Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。 有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下： （1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句 （3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句 另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有： It is necessary (important, natural, strange, etc.) that … It is a pity (a shame, no wonder, etc.) that… It is suggested (requested, proposed, desired, etc.) that… 2. 宾语从句 名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。 1. 由连接词that引导的宾语从句 由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。例如：He has told me that he will go to Shanghai tomorrow.他已经告诉我他明天要去 上海。 We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。
宾语从句和表语从句详解与练习
宾语从句和表语从句详解 名词性从句指的是在整个句子中起名词作用的从句。这种从句可以做主语、宾语、表语、同位语等，所以这类从句包括主语从句、宾语从句、表语从句和同位语从句。各种名词性从句的结构都是相同的，即由if，whether，that和各种疑问词充当连接词，后接陈述语序。 例如：What they are doing seems very important．（主语从句） 他们在做的事似乎很重要。 My hope is that he will be the best student in the class．（表语从句） 我的愿望是他能够成为班上最好的学生。 Nobody knows who he is．（宾语从句） 大家都不知道他是谁。 I don't like the idea that money is everything．（同位语从句） 我不喜欢金钱就是一切这一观点。 引导名词性从句的连接词中，除了that，if和whether之外其它的都作从句中的一个成分。 【宾语从句】 在句子中作动词或介词宾语的从句叫做宾语从句。引导宾语从句的词有连词that，whether，if；连接代词who，which，what以及其强调形式whoever，whichever，whatever；连接副词when，where，why，how等。 例如：Do you know where the Greens live I have no interest in how rich he is． 宾语从句主要用于下面五种结构： 1．由that引导的宾语从句（that 引导宾语从句时，特别是在口语中可省略） The boy believes that he will travel through space to other planets． that引导的宾语从句多用于say，think，insist，wish，hope，demand，imagine，wonder，know，suppose，see，believe，agree，admit，deny，expect，explain，order，command，feel，dream，suggest，hear，mean，notice，prefer，request，require，propose，declare，report等后。 当主句谓语动词是think，believe，suppose，expect 等词，而宾语从句的意思是否定时，常把否定转移至主句表示。例如：I don’t think it is right for him to treat you like that．（＝I think it is not right for him …．） that不能省略的情况： （1）当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。如： He said （that）you were too young to understand the matter and that he was asked not to tell you． （2）当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。如： Just then I noticed，for the first time，that our master was wearing his fine green coat and his black silk cap． （3）当that从句是双宾语中的直接宾语时，that不可省。如： I can’t tell him that his mother died． 2．由特殊疑问词引导的宾语从句 这样的宾语从句实际上是由特殊疑问句变化而来的，宾语从句要用陈述句语序。用于这种结构的动词常常是：see，say，tell，ask，answer，know，decide，show，find out，imagine，suggest，doubt，wonder，discover，understand，inform，advise等。
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.
主语从句与宾语从句
主语从句与宾语从句 一、名词性从句是四位从句的总称：主语从句、宾语从句、同位语从句、表语从句。这些从句都起到类似于名词的作用。 主从：一个句子充当大句子的主语，就叫主语从句。例如； What I need is money.(主语是What I need作大句的主语) It was not obvious that water is fundamental to the development of life.（It是形式主语，真正的主语是that 从句。） 主语从句的位置有两种，一种是放于句首；一种是用It 作形式主语，从句被放后面。 二、宾语从句：一个小句子充当大句子的宾语。 He asked me how old I was . She took it for granted that I’d be back home an hour ago.（It 作形式宾语，真正的宾语是后面的that从句。） 考点一：语序 What I want to do is to go home immediately.陈述语序。 I asked where the famous restaurant was .陈述语序。 名词性从句的语序应该是陈述句语序。 删除疑问语序（be /助动词、情态动词+主语） 考点二：引导词 That（没成分） That the earth moves around the sun is known to all.(that 引导的句子作大句子的主语，that不能丢。) Whether /if （有时互换，主语从句只能用wheather引导，不能用if .可用if 的地方都能用wheather。） Whether the meeting will be put off depends on the weather . 疑问代词：what,who, whom,which,whose 在从句中有成分 What he has is just money.（在从句中有成分作宾语） 疑问副词：where ,when,why,,how在从句中有成分 Why he didn’t attend class is not know yet. That：引导名词性从句时无成分，无词义，有时可以省略。 Whether /if引导名词性从句时无成分，是否。 特殊疑问代词：主，宾，表，定。 疑问副词：状。 考点三：no matter+疑问词（what）VS疑问词（what）+ever Whatever he says must be put down . No matter what he says/Whatever he says,I will not change my mind. 意思相同，但语法不一样。第一句主从，第二句让步状语从句。以ever开头的引导主从或者状语从句，而以no matter 开头的不能引导名词性从句，只能引导状语从句，所以选ever 就一定对。 考点四：建议、命令、要求类+宾从 The doctor suggested that an operation (should)be done immediately on the patient. 初中讲过当主句是一般过去时态的宾语从句：主过去，从句也过去。当主句的动词是建议、命令、要求类的动词时，后面的宾从必须是should+动词原形且should可以省略。此时不管。主语是谁，不管主句是什么时态都不能改变动词是原形的要求.once表示建议、命令、要求类的动词suggest,advise,propose,demand,require,insist,request,ask,command,order后面如果后
3.3 宾语从句 表语从句 教案
教学过程 一、课堂导入 概念引入 She doesn’t know (th at) her father is seriously ill. 她不知道她父亲病得很严重。 Can you tell me how I can get to the railway station? 你可以告诉我怎么去火车站吗？The problem is when they can get there. 问题是他们什么时候能到那儿。 The problem is whether we can replace her. 问题是我们能否替换她。
二、复习预习 复习什么是宾语和表语，列举作宾语和表语的词性。
三、知识讲解 知识点1：宾语从句的定义 置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾语从句的语序必须是陈述语序。有些形容词（afraid ,sure ,glad等）之后也可以带宾语从句。 She doesn’t know (that) her father is seriously ill. Can you tell me how I can get to the railway station? 划线部分是宾语从句。
【考查点1】宾语从句的引导词 连词：that (that 常可省略),whether, if 代词：who, whom, whose, what ,which, whoever, whomever, whatever, whichever 副词：when ,where, how, why 等。 She reminded me that I had a meeting to attend. I wonder whether(if) they will come to our party. None of us knows where these new parts can be bought.
表语从句与主语从句
表语从句与主语从句 表语从句和主语从句以及宾语从句都要用陈述语序。 Ⅰ.表语从句 在复合句中，位于系动词之后作表语的从句称为表语从句。它位于主句的系动词之后， 最为重要的是我们应该为牛找到足够的水。 The doubt is who has taken away the valuable vase. （主语，人） 疑点是谁拿走了那只贵重的花瓶。 My topic today is what most scientists are researching.（宾语，物，没有选择范围） 我今天的话题就是大多数科学家正在研究的课题。 The problem is which school will be chosen.(which在从句中作定语) 问题是哪一所学校将被选中。 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。 表语从句中应注意的问题 (1)because，why引导的表语从句。 because引导表语从句时，表示“因为”，why引导表语从句时，表示“……的原因”，相当于the reason why。 That’s because he didn’t understand me. (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。
