3、。因此，根据它在句中不同的语法功能，名词性从句分为主语从句、宾语从句、表语从句以及同位语从句。名词性从句（Noun Clause）主语从句Subject Clause名词性从句Noun Clause宾语从句Object Clause表语从句Predicative Clause同位语从句Appositive Clause【分类】1.主语从句：从句在句中充当主语成分2.宾语从句：从句在句中充当宾语成分（可以作谓语动词、介词、不定式等非谓语动词的宾语）3.表语从句：从句在句中充当表语成分，一般放在连系动词之后。4.同位语从句：从句在句中充当同位语成分，其一般跟在一些抽象名词(idea,belief,

4、fact,truth,problem,news等)后面,对名词作进一步解释说明。【引导名词性从句的连接词】连词：that（无意义，宾语从句中可省略）,whether/if（表是否，不能省略），as if(好像,不能省略），because（因为,不能省略),不充当从句的任何成分。连接代词:what,who,whom,whose,which,whatever,whoever，whichever（在从句中充当主语、宾语或定语等成分；指人或事；不能省略）连接副词:when,where,how,why（在从句中充当状语成分；表时间、地点、方式、原因；不能省略）【按分类分析】1主语从句主语从句是在复合句中

5、作主语的句子；通常位于句末，句首则采用it作形式主语。注意，what引导的主语从句一般不用it作形式主语。(1)常以it作形式主语的句型有：It is形容词that.It is certain that she will do well in her exam.毫无疑问她考试成绩会很好。It is名词词组(no wonder,an honour,a good thing,a pity,no surprise,common knowledge,a surprise,a fact,etc.)that.Its a pity that we cant go.很遗憾我们不能去。It is过去分词(sai

6、d,reported,thought,expected,decided,announced,arranged,etc.)that.It has been suggested that much should be done to prevent the river from being polluted.有人建议应做更多的工作阻止河流遭受污染。It appears/seems that./It happens that./It occurred to me that./It turned out that.It turned out that nobody remembered the add

7、ress.结果发现没人记得这地址。It doesnt matter that./It makes no difference that.It doesnt matter whether she will come or not.她是否来这无关紧要。(2)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。Does it matter much that they will not come tomorrow?他们明天不来很要紧吗？(3)当主语从句出现在感叹句中时，以it作形式主语，而把主语从句后置。How strange it is that the childre

8、n are so quiet!孩子们这么安静真奇怪！（2013山东高考）Its good to know _ the dogs will be well cared for while were away.A.what B.whose C.which D.that【解析】选D。考查主语从句。句意：当我们离开不在的时候，知道这些狗将会被很好地照顾真是太好了。本句中it是形式主语，代替后面的从句，而从句中意思及语法结构完整，不缺任何成分，所以选that，并且不能省略，而A项what什么；B项whose谁的；C项which哪一个，都在句子中充当成分，所以被排除，故选D。真题在线(2012陕西高考)N

9、o matter where he is,he makes _a rule to go for a walk before breakfast.A.him B.this C.that D.it【解析】选D。考查代词。句意:不管他在哪里,早饭之前去散步成了他的习惯。句中涉及make复合宾语:to go for a walk.是真正的宾语,a rule 是宾语补足语,it为形式宾语,四个选项中只有D项it 可以作形式宾语或者形式主语。(2012全国卷)It is by no means clear_the president can do to end the strike.A.how B.whi

10、ch C.that D.what【解析】选D。考查名词性从句。句意:总统会采取什么措施来结束这次罢工还不清楚。根据句子结构可以判断此处it作形式主语,真正的主语是后面的从句。从句中do后面缺少宾语,这样可先排除A、C两项。how是副词,不能作宾语,that在名词性从句中不作成分。根据句意可知which(哪一个)放在此处不合适。2宾语从句主从复合句中起宾语作用的从句称为宾语从句。(1)引导宾语从句的连词that一般可以省略，但在及物动词之后跟有两个或两个以上的宾语从句时，只有第一个that可以省略。The teacher said(that)the text was very important

11、 and that we should learn it by heart.老师说这篇课文非常重要，我们应该用心背下来。(2)表 示“心 理 活 动”的 形 容 词：afraid,anxious,aware,ashamed,annoyed,certain,confident,content,convinced,determined,disappointed,glad,happy,proud,pleased,sure,surprised,satisfied,thankful,worried等后可接宾语从句。He was afraid that he would lose.他担心会输。I am s

12、ure that I put the money in the box.我肯定把钱放在盒子里了。(3)若主句谓语动词为think,consider,suppose,believe,expect,fancy,guess,imagine等，一般要把否定词转移到主句谓语上，从句谓语用肯定式(此时主语往往为第一人称，偶尔为第三人称；否定词never,seldom,hardly,little无此用法)。I dont think his decision is wise in reality.实际上，我觉得他的决定并不明智。I dont believe that he is a dishonest man

13、.我认为他是个诚实的人。(4)在think,believe,imagine,suppose,guess,hope等动词以及Im afraid之后，可采用so代替肯定的宾语从句，也可采用not代替否定的宾语从句。Do you believe the news story?I believe so.你相信这个新闻故事吗？我相信。Has Ann got into university?I am afraid not.安上大学了吗？恐怕是没有。(2012北京高考)Jerry did not regret giving the comment but felt _ he could have expre

14、ssed it differently.A.why B.how C.that D.whether【解析】选C。考查名词性从句。句意:Jerry并不后悔提出自己的意见,但是他感觉他本来可以换种方式表达的。由句式结构可知felt后面是一个宾语从句,从句中不缺少任何成分,故应用that引导。why在从句中作原因状语;how在从句中作方式状语;whether意为“是否”。真题在线（2013北京高考）Experts believe _ people can waste less food by shopping only when it is necessary.A.whyB.where C.that

15、D.what【解析】选C。考查名词性从句。句意：专家们相信人们只在必要的时候购物能减少食物的浪费。that引导宾语从句，后面句子不缺少任何成分，只起连接作用，故使用that。3表语从句在句中作表语的从句称为表语从句；学习表语从句应该注意以下几点。(1)通常只用that引导表语从句的情况。句子的主语为the reason时，表语从句采用that引导，表示原因，此时不用because。The reason why she was ill was that she had eaten bad meat.她生病的原因是她吃了变质的肉。句子的主语为the result时，表语从句采用that引导。The

16、 result is that many of them become fat.结果是他们中许多人发胖了。由why引导的从句作主语时。Why we decided to put off the match is that the weather was too terrible.我们决定推迟比赛的原因是天气太糟糕了。(2)as if/though引导的表语从句通常置于系动词look,seem,sound,be等后面；表语从句既可以采用虚拟语气，也可采用陈述语气。It sounded as if somebody was knocking at/on the door.听起来好像有人在敲门。Sh

18、r意为“是否”。真题在线【名词性从句考点归纳】1名词性从句必须采用陈述语序。I want to know what he has told you.我想知道他告诉了你什么。She always thinks of how she can work well.她总是在想怎样能把工作做好。2.it作形式主语或宾语：在名词性从句中，为了使句子保持平衡，常用先行词it来代替主语从句或宾语从句，而把主语从句或宾语从句放到后面，尤其是连词that引导的主语从句常用于此句式中。I find it strange that she doesnt want to travel.她竟不想旅游,我觉得很奇怪。It

19、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。3.在名词性从句中 that与what的差异：what在从句中要充当某个成分(主语、宾语或表语)，在任何情况下都不能省略，表示“(the thing or things that.;whatever)的事物；无论什么；凡是的事物”。that本身没有词汇意义，在从句中不充当任何成分，在口语和非正式文件中，宾语从句中的that常常省略。_you have done might do harm to others.你所做的事或许对别人有害处。I spent _ little time I h

20、ad with my family.我仅有的一点儿时间都和家人在一起度过了。No one knows_will happen next.谁也不知道下一步有什么事。I think _you will like the stamps.我认为你会喜欢这些邮票的。即学即练Whatwhatwhat(that)4.whether和if的差异：(1)引导主语从句、表语从句或同位语从句，只能采用whether。Whether there is life on the moon is an interesting question.月球上有没有生命是个有趣的问题。(2)介词宾语只用whether引导。He wa

23、句。句意：取得最大成功的唯一方法就是充分相信你在赛场上比其他人更好。该空引导belief的同位语从句。并且在从句中既不作任何句子成分，也无任何意义，只能用that。how与which在同位语从句中，不仅有意义而且作成分；whether在同位语从句中，虽然不作成分，但却有意义。故选B。5宾语从句和主句的时态呼应：(1)当主句谓语动词为现在时态或将来时态时，宾语从句可以选择适当的时态。Will you tell me how I can keep fit?你能告诉我如何保持健康吗？(2)当主句谓语动词为过去时态时，为保持时态一致，宾语从句应采用相应的过去时态。Jack told me that h

24、e had been there twice.杰克告诉我他去过那儿两次了。(3)当主句谓语为过去时态时，宾语从句表示客观真理、客观存在的事物、格言时,仍然采用一般现在时。Long ago,people knew that there are four seasons in a year.很久以前，人们就知道一年有四个季节。6.连接代词whoever,whatever,whichever引导名词性从句的含义：(1)whoever的用法：(the person or people who.)的那个人Whoever said that?到底谁讲的这话？(any person who.)的任何一个人T
