What she couldn’t understand was that fewer and fewer students showed interest in her l essons. 我们不能理解越来越少的学生对他的课不感兴趣.3、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.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.4、由关系副词引导的表语从句.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 nei ther 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.5、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 see ms as if he didn’t know the answer.好像他不知道答案.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 out系动词的固定搭配:come true, fall asleep, fall ill, go bad, come right, run wild连接词：that / whether /as if /asthough (if不引导表语从句)连接代词：who / whom / whose / which/ what连接副词：when / where / why / how /because注：引导表语从句的连词that间或可以省略.The truth is（that）I didn't go there. 事实是我没去那儿.［考题1］The traditional view is ____ we sleep because ourbrain is “programmed” to make us do so.A. whenB. whyC. whetherD. that［答案］ D［解析］下划线处之后是包含一个原因状语从句的表语从句, 如果看不出它是充当整个句子结构的表语从句将难以把握整个句子的意思.因此, 应选择可引导名词性从句且不充当任何成分的that.［考题2］You are saying that everyone should be equal, and this is ____ I disagree.A. whyB. whereC. whatD. how［答案］ B［解析］下划线处的引导词引导系动词is后的表语从句并在该表语从句中充当地点状语(“disagree”属于不及物动词, “I disagree”本身是完整的主谓结构), 下划线应填入引导词where, 表语从句“where I disagree”的意思是“我不同意之处、我不同意的地方”.［考题3］— I drove to Zhuhai for the air show last week.— Is that ____ you had a few days off?A. whyB. whenC. whatD. where［答案］ A［解析］下划线处的引导词引导与系动词is连用的表语从句并在该表语从句中充当原因状语, 下划线应填入表示“因此……”(指因某种原因所造成的结果)的引导词why.［考题4］____ she couldn’t understand was ____ fewer and fewer students showed interest in her lessons.A. What; whyB. That; whatC. What; becauseD. Why; that［答案］ A［解析］第一个下划线处的引导词引导主语从句并在该主语从句中充当宾语, 特指她所不理解的事情, 应填入关系代词型的引导词what；第二个下划线处表示“因此……”(指因某种原因所造成的后果, 由why 引导对应的名词性从句)而不是“为什么……”(指原因、理由, 由because引导对应的名词性从句), 应填入引导词why.［考题5］____ made the school proud was ____ more than 90% of the students had been admitted to key universities.A. What; becauseB. What; thatC. That; whatD. That; because［答案］ B［解析］第一个下划线处的引导词引导主语从句并在该主语从句中充当主语, 特指令校方骄傲的事情, 应选用关系代词型的引导词what；第二个下划线处引导表语从句表示原因、理由, 应由that引导对应的名词性从句.［考题6］—Are you still thinking about yesterday’s game?—Oh, that’s ____.A. what makes me feel excitedB. whatever I feel excited aboutC. how I feel about itD. when I feel excited［答案］ A［解析］A选项的意思是“令我感觉激动的事物”；B选项的意思是“我觉得激动的任何事物”；C选项的意思是“我对它感觉的方式”；D选项的意思是“令我感觉激动的时间”.四个选项中A最适合跟代表“game”的主语that对应, 充当表语从句.表语从句与宾语从句的关系不属于的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 enred red the room警察想知道的是你什么时候进的房间.The The trouble is that we are short of funds困难是我们缺乏资金.This This is what we should do这是我们应当做的.That”s s why I want you to work there那就是我要你在那儿工作的原因.His His first question was whether Mr. Smith had arrived yet 他的第一个问题是史密斯先生到了没有.注意：从句中的疑问句用正常语序, 即陈述语序.as as if, as though, becau也可用来引导表语从句.She She seems as if she had done a great thing她看起来好像做了一件大事.It It is because you eat too much那是因为你吃得太多了.表从练习一1.

主语从句

主语从句（Subject Clause）一、概念1. 主语。

主语是句子陈述的对象，说明是谁或什么。

主语可以由名词、代词、形容词、分词、副词、数词、动词不定式（短语）、动名词和从句等来充当。

①My school is not far from my house. （名词做主语）主语②We like our school very much. （代词做主语）③Two add two is four. （数词做主语）④This is an article. (指示代词做主语)⑤Seeing is believing. （动名词做主语）⑥To see is to believe. (动词不定式做主语)⑦What I mean is to work harder. (从句做主语)2. 主语从句。

在句中充当主语的从句叫做主语从句。

连接代词主语（从句）②Whether he will come here on Wednesday is not certain. 还没肯定他星期三是否会来。

连接副词主语（从句）③Where he comes from is unknown. 他从哪里来还不清楚。

④What’s done is done. 事已成定局。

★主语从句结构：连接代词/副词+句子二、主语从句的连接词⑴用从属连词that和whether引导。

主语从句

主语从句作句子主语的从句叫主语从句。

主语从句通常由下列词引导：1从属连词that，whether 等；2连接代词what，who，whic h，whatever，w hoever，w hom 等；3 连接副词how，when，where，why 等。

一、从属连词：that，whether等.1、that 引导主语从句只起引导作用，本身无实际意义，在主语从句中不充当任何成分，但不能省略。

That he w ill w in is c ertain.他肯定会赢。

Whether he’ll c ome here isn’t c lear. 他是否会来这里还不清楚。

2、由that 引导的主语从句有时为了使句子结构平衡, 避免“头重脚轻”, 常用it 作形式主语, 而把从句放在后面。

例：1. That he w ill refuse this piec e of advic e is impossible.____________________________________3、这样就构成了下面一些常用句型:（1）: It is + n. +从句It is a pity/shame that... 遗憾的是……It is a surprise that…令人惊奇的是…（2）: It is + adj. +从句It’s certain that…肯定…It is possible that... 很可能……*（3）: It +不及物动词+从句It happened that... 碰巧……It occurred to me that…我突然想起…*________________(刚好)I came into the office at that time.（4）: It + be +过去分词+从句It is said that... 据说……It is believed that...据信……;人们相信……It is suggested that + (should）do... 建议……It must be admitted that…必须承认……*___________________(据报道)20 people were killed in the accident.*______________________(建议)we should eat more v egetable and do more exercise.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 nec essary (important, natural, strange, etc.) that … It is suggested (requested, proposed, desired, etc.) that…众所周知（1）It is known to us that二、连接代词who ，what ，which, whatev er, whichev er, whoev er ,whom(Who, whom, which, what可以和ever构成合成词，和what一样引导从句，ev er起到强调作用。

主语从句

主语从句一、定义：在句子中担当主语的是一个从句，这个从句就叫做主语从句。

通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。

二、引导词：（1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。

That you will win the medal seems unlikely. 你想获得奖牌看起来是不可能的。

That you are so indifferent bothers me.你如此冷淡使我很烦恼。

That she survived the accident is a miracle.她在事故中幸免于难简直是奇迹。

That she was chosen made us very happy.她当选了使我们很高兴。

That they should refuse to sign the petition required great courage. 他们拒绝在请愿书上签字这是需要很大勇气的。

（2）用连词whether 引导的主语从句:whether有含义(是否),在句中不做成分,不可以省。

Whether she is coming or not doesn’t matter too much. 她来不来都无关紧要。

Whether they would support us was aproblem. 他们是否会支持我们还是一个问题。

Whether we will go for an outing tomorrow remains unknown.（3）用连接代词引导的主语从句(在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分).What you need is more practice. 你所需要的是更多的训练。
