在引导限定性定语从句时，that有时相当于in which, at which, for which或at which
在复合句中用作主语的从句叫主语从句。
A 为了强调主语从句的内容，可将从句置于句首
That you are leaving is a pity.
你要走，真遗憾。
What matters is how you live.
重要的是你如何生活。
Where he lives is not clear.
他住哪儿不清楚。
Who will stay makes no difference.

连词that引导的主语从句位于句首时，that不可以省，反意问句用it。
That he has lost his watch is not true, is it?
他手表丢了不是真的，是吗？
Whether the football game will be played depends on the weather.
足球比赛是否举行将视天气而定。
B 大部分主语从句都可以用it作形式主语
为了保持句子平衡，主语从句常用it作形式主语，将主语从句后置。用it作形式主语的主语从句结构有如下几种：
It is + 名词+ that从句
It's a pity that we can't go.
很遗憾我们不能去。

你们中任何想来参加我们晚会的人都欢迎。
C 使用虚拟语气的主语从句
在It is suggested, ordered, requested, insisted, etc. + that从句中，谓语部分用should + 动词原形，should常被省略。(详见第3章虚拟语气)
It is suggested that we (should) do the experiment a second time.
有人建议我们再做一次实验。
在It is important, natural, necessary, etc. + that从句中，谓语部分常用should + 动词原形，should常被省略。

我们要维持生态平衡，这是重要而且必不可少的。
在It is funny, strange, surprising, a pity, a shame, no wonder, etc. + that从句中，有时谓语部分用should + 动词原形，来表达说话者的感情色彩，此时should也可省略。
It is a pity that you (should) miss such a good chance.
真遗憾你竟然失去这么好的机会。
2完形填空很重要的一点就是考察你的词组积累。有些题目你不知道他的意思那你就看一下他的短语。有没有你学到过的词组。套进去的话正确率是很高的!!!
有时候你遇到一个生词没关系不要怕(这是做英语题很重要的一点!!)不管你觉得这题目多难都不要被吓倒!!硬着头皮也要往下看，说不定就柳暗花明了。有时候下文就有提示的。还有些时候使一些无关紧要的词(像地方，名字等)不影响文章理解，就不用管它了。当然如果是平时练习的话，那你就要翻翻词典把意思查出来了。要注意平时的积累。
还有不知道就猜，考试中不可能都是学过的单词，有30%的生词。大部分都是可以根据上下文意思才出来的。不要怕大胆做下去好了。
如果实在不知道那就只能跳过去，接着把下面的做完在会上来解决那个不会的。难题上不要停留太久，要注意时间把握。
1。The storm left,(having caused) a lot of damage。
因为动词+ing 1）在语态上表主动；2。在时态上表进行
分析：having caused的逻辑主语是The storm，他们的关系是主动的关系。因为这暴风雨导致了很多破坏。所以要用ing 形式。
2。You were stil not ()your computer when you left.
A:having shutting down B:to shut down C:to have shut down
选A.:having shutting down
过去进行时态。另外是用排除法，B和C都是不定式。在英语中be + 不定式表示将要做某事。与句意不符。
3。( )in English ,she did not heard the knocking.(lose)
填Lost
因为lose 与其逻辑主语she是被动的关系，表示她太专注于英语了。直译可
以这样来理解：她迷失在英语中了。（She was lost in English)
Rainforests are being cleared for valuable timber and other resources to speed up the economic growth of the nationsin which they are located .
为了加速他们各自所在国家的经济发展，热带雨林作为有价值的原木和其他资源正为人们所砍伐。
Ocean currents affect the climates of the lands near which they flow.
洋流影响其流经的附近地区的气候。
They explained the reason to us why they had hated us before.
他们向我们解释为什么他们不喜欢我们的原因。
Earlier , the Babylonians had attempted to map the world , but they presented it in the form of a flattened disc rather than a sphere , which was the form adopted by Ptolemy . （此句中，非限定性定语从句是对先行词a sphere进行补充、说明。）
更早之前，巴比伦人曾试图绘制世界地图，但是他们把它绘制成平盘状而不是托勒密所采用的球体状。
The combination of satellites, which transmit information , computers , which store information , and television , which displays information , will change every home into an education and entertainment center .
（此句中，三个非限定性定语从句分别对三个先行词：satellites ，computers和television 进行补充、说明。如果去掉这三个非限定性定语从句，那么句子可简化为：
The combination of satellites , computers and television will change every home into an education and entertainment center .）卫星能传输信息，计算机能储存信息，电视能显示信息，把这些手段结合起来可以使每个家庭都成为教育娱乐的中心。
The sun heats the earth , which makes it possible for plants to grow .（此句中，非限定性定语从句是对全句进行补充、说明,将全句表达的意思看成"一件事情）。太阳给予大地热，这就使植物的生长成为可能。
The old man has a son , who is in the army .（此句中，非限定性定语从句是对先行词son 进行补充、说明。但本句所传达的信息是："这位老人只有一个儿子" 。如果将此句改写成限定性定语从句：
The old man has a son who is in the army . 那位老人有一个在部队工作的儿子。那么，限定性定语从句就要对先行词son进行限定、修饰。这样一来，句子所传达的信息就变成了："这位老人有一个儿子在部队工作，还有其他的儿子在干别的工作"。）那位老人有一个儿子，他在部队工作。
〔注〕值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导
By the time you arrive in London, we will have stayed there for two weeks.
I still remember the first time I met her.
Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.
7. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格
8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用there is来引导
主语从句做主语，主句谓语动词的单复数需根据从句表示的单复数意义决定。1．what引导的主语从句做主语 （1）通常情况下，由what引导的主语从句放在句首时，其后的谓语动词，按语法一致的原则用单数。eg:What she said is correct. What caused the accident is not clear. （2）当主句中的表语是复数形式，或what从句的谓语动词及其补足语均为复数形式时，主句的谓语动词应用复数。eg:What he gave me are five English books. What are used as chief building materials today are steel and concrete. （3）当what引导的主语从句是一个由and连接的并列结构时，应根据句意确定其表达的单复数意义，然后决定主句谓语动词的单复数形式。 eg:What he says and acts does not concern me. What he says and acts do not agree. What I say and what I think are no business of yours. 2．由其它词引导的从句做主语时，谓语动词用单数形式。 Whether they will hold a party or not has not been decided. Who is responsible for the accidents is not clear. 3．当同一个主语从句是由两个不同的引导词引导时，因为它表达的还是同一件事，因此，谓语动词一般用单数。 eg:When and where we should hold the meeting has not been decided yet. 4．当主语是由两个由and连接的主语从句组成，通常表示的是两件不同的事情，主句谓语动词需用复数形式。 What you eat and how much you exercise are important factors in a weight loss program. What caused the accident and who was responsible for it remain a mystery to us.
初中重点语法 从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。（参见以下各条） 3、各从句在句子中的位置以及用法： (1) 表语从句：在句子中作连系动词的表语的从句,它位于主句中的系动词之后。 例如：That is why he did not come to school yesterday. / It is because you are so clever. (2) 宾语从句：在句子中作及物动词或介词的宾语。 ①基本形式：（主句＋）连词+从句主语+从句谓语+... ②关于宾语从句连词的选择： 若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略; 若从句来源于一个一般疑问句,连词则用if 或whether; 若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等) 例如：They believe that the computer will finally take the place of human beings.(他们相信计算机终将 代替人类。) (从句本来就是陈述句)/ I wonder whether I should say something for him to the headmaster.(我不知道是不是该为他在校长跟前说点什么。) (从句来源于一般问句Shall I say something for him to the headmaster?) / He asked me where he could get such medicine. (他问我在 哪儿能搞到那样的药。) (从句来源于特殊问句Where can he get such medicine? ) ③宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时； 如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。如：I think I will do better in English this term. (我想本学期我的英语会学得好点。) / The teacher asked the boy if the earth is round. (老师问那个男孩地球是不是圆的。) ④下列结构后面的从句一般也作为宾语从句看待： be sorry / afraid / sure / glad +that从句,如：I’m sorry I’m late. (对不起,我迟到了。) / I’m afraid he isn’t in at the moment. (恐怕他此刻不在家。) (3) 状语从句：在复合句中作状语,其位置可以在主句前或主句后。状语从句可以分为时间、地点、原因、 目的、结果、比较、让步、条件等几种。状语从句由从属连接词引导。 时间状语从句通常由when ,as ,while, after, before, since, as soon as ,since, till (until), while, whenever 等引导。时间状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该 用现在时替代。如：When you finish the work, you may go out to play with Sam. (你完成工作就可 以出去和Jim一起玩了。) / I won’t leave until Mum comes back. (妈妈回来了我才会走。) 地点状语从句通常由where, wherever等引导。如：Go back where you came from! (哪里来还滚到哪里去！) / I will never forget to catch the thief who stole my necklace wherever he may be. (我永远也不会 忘记去抓住那个偷我项链的贼,无论他会在哪里。) 原因状语从句通常由because, since, as等引导,一般放在句首或句尾。如：He went abroad because his father had found a good university for him. (他出国了,因为他父亲给他找了一所好大学。) 目的状语从句通常由so that..., so...hat..., in order that...等引导,往往放在句尾,从句中通常含有can / could / may / might等情态动词。如：He got up earlier so that he could catch the first train. (他起身 更早为的是赶上第一班车。) 结果状语从句通常由so that..., so...that... 等引导,放在句尾。结果状语从句一般表示已经发生的事情,故多为过去时态。如：He lost so many bikes that he decided never to buy a new one. (他丢了那么多 辆自行车,他决定再也不买新车了。) 比较状语从句通常由as, than, as (so)...as等引导,一般省略从句的谓语部分,只剩下名词或代词(用主格或宾格均可)。如：Jane is much taller than I/me. (Jane比我高多了。) / I don’t have as many books as you (do). (我书没有你多) 让步状语从句通常由though (although), as, even if( even though), however, whatever等引导。如：Even if you pay the debt(债务) for me, I will not thank you because it has nothing to do with me. (即使你替 我还了债我也不会感谢你,因为它与我毫无关系。) / He wears a T-shirt though it is very cold. (他穿 了一件T恤衫,尽管天很冷。)
练习（主语从句） 一、.关联词分类和基本句型： (1)从属连词that。如：That they were indeed 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。 ______ we need more equipment _____ quite obvious. 我们需要更多的设备，这是很明显的。 (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。 ______ he will join us won't _____ too much difference.他是否和我们一起干无所谓。 (3)连接代词who, whom, whose, what, which, whoever, whatever, whichever 连接副词where, when, how, why。如： What you need is more practice. 你需要的是更多的练习。 Whoever wants it may have it. 谁要都可以给他。 _____she did ____ not yet known. 她干了什么尚不清楚。 _____ this happened is not _____ to anyone. 这事怎样发生的，谁也不清楚。 ______ comes _____ welcome. 不论谁来都欢迎。 二、主语从句后置： 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。 _____ _____ probable ______ he told her everything. 很可能他把一切都告诉她了。 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 _____ ______ that we can’t go.很遗憾我们不能去。 It’s ______ _______ that our team should have won the game. 我们没赢这场比赛真意外。 C.It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+that从句。如： It is ______ ______Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。 It is ______ _______ China has sent another man-made earth satellite into orbit. 据报道中国又成功地发射了一颗人造地球卫星。 D.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。 _____ _______ ______ I was out that day. 碰巧我那天外出了。 E.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 ______ _______ she will come or not. 她是否来这无关紧要。 It _____ _____ difference ______ we shall have the meeting. 我们在哪里开会毫无区别。 三、注意连接代词whoever, whatever, whichever等引导主语从句的含义： _______ comes will be welcome. (whoever=the person who) 来的都是客。 _________ he did was right. (whatever=the thing that) 他所做的事情都是正确的。 ________ _____ ______ comes in will receive a prize. (whichever=anyone of you who) 你们当
名词性从句---主语从句 1. What is needed for the space trip is careful preparation. 2. Her wish is that she can lose weight soon. 3. I think that woman can reach every high achievements in many fields of science. 4. We were very excited at the news that our team had won. 引导名词性从句的关联词可分为三类： 一．从属连词：that（无任何词意） whether, if（均表示“是否”表明从句内容的不确定性） as if ,as though（均表示“好像”，“似乎”）以上在从句中均不充当任何成分二．连接代词：what, who, whom, which，whose, whatever, whoever, whichever(作主宾表定) 三．连接副词：when, where, how, why(作状语) I.主语从句 1.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。 2.位置：主语从句是在复合句中充当主语的从句，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。 3.引导主语从句的关联词： (1)从属连词that,whether,if (在从句中不充当成分，仅起连接作用) That Jack won the match yesterday surprised us. Whether he’ll come here isn’t clear. (此处不能用if) (2)连接代词who, whom, whose, what, which, whoever, whatever, whichever(充当主宾表定) What she did is not known. Whoever comes is welcome. (3)连接副词where,when,how,why(在从句中充当状语) How this happened is not clear to anyone. When the meeting will be held is decided by our manager. 4.有时为了避免头重脚轻，常用it作形式主语，而把真正主语放在句子末尾。 How the book will sell depends on its author. = It depends on its author how the book will sell. That he is the best student in the class is obvious. = It is obvious that he is the best student in the class. 用it作形式主语的几种常见结构： (1) It is ＋名词＋从句 It is a fact that … 事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) It is ＋形容词＋从句 It is natural that… 很自然It is strange that… 奇怪的是… (3) It is ＋不及物动词＋从句 It seems that… 似乎… It happened that… 碰巧… It ap pears that… 似乎… (4) It ＋过去分词＋从句
（九）复合句——状语从句 (九) 复合句——状语从句 说明: 所有相关复合句的综合练习将出现在“从句综合练习”章节 考点归纳 1. 状语从句的类型: 时间状语从句、地点状语从句、原因状语从句、条件状语从句、目的状语 从句、结果状语从句、让步状语从句、比较状语从句、方式状语从句 2. 时间状语从句: ⑴ 连接词及固定搭配: when, while, as, since, after, before, until / till, once, each time, every time, any time, whenever, as soon as, the moment, the minute, the instant, hardly / scarcely / barely / rarely … when / before, no sooner … than, just as, directly, immediately, instantly, shortly after, soon after, it won ’t be long before, by the time, it ’s the first time that, it ’s … since, the first time, the last time ⑵ as soon as 与hardly … when 等结构都能表示“一……就……”，但两者的时态不同；前者一般主从句均为一般时态，表示一般情形遵从主将从现原则；后者一般主句为过去完成时，从句为一般过去时，且在句首引起倒装 ⑶ 特殊地，可用the minute, each time, the first time 等名词或名词短语充当连接词引导时间状语从句，该类词称为边际从属连词 3. 地点状语从句可由where, wherever 引导，前者指特定地点，后者为无特定地点 4. 原因状语从句: ⑴ 可由because, since, now that, as, in that 引导，注意for, so, with + n . + 宾补结构 ⑵ 现代英语中，because 与for 都可引导原因状语从句，且都能表示“直接理由”与“间接理由”，如It must be very late, for the streets are quite deserted. (间接理由) 上句中的for 实也可替换为because ，只是在两者同时存在时，使用for 语势较弱，更显出说话人的推断的不确定性，说明说话人的推断略显主观臆断 ⑶ 在表述直接理由时，because, since, as 从句位置既可在主句前，也可在句尾；而for 则只能位于主句后；此外，because 可回答why 问句，because 前可加入诸如simply 的修饰语，because 从句也可作为强调句的强调部分，这些场合下because 不能替换为for ；若because 也表述的是间接理由，则其位置只能在主句后 5. 条件状语从句的连接词及相关搭配: if, unless ( if … not), on condition that, given that, as / so long as, suppose that, even if, even though, provided that, in case, lest, given that, considering that, since, now that 等 6. 目的状语从句可由that, in order that, so that, for the purpose that, in the hope that 等作连接词或 固定搭配，常与情态动词连用 7. 结果状语从句: ⑴ 连接词及固定搭配: that, so … that, such … that, so that 等 ⑵ such 修饰名词，so 修饰形容词或副词，such / so 结构类似于what / how 的固定结构；当 such 修饰可数名词单数时可将其与so 结构互换；若such 修饰不可数名词或可数名词复数时则无法互换 ⑶ 当many, few, little, much 表多少修饰名词时只能用so ；若little 不表多少，且修饰可数名词单数时只能用such 8. 让步状语从句: ⑴ although, though, as, while, even if, even though, however, whatever, no matter 系列等 ⑵ though 引导的让步状语从句可以倒装(也可不倒装)，作用相当于as (必须倒装)，此时though 不能与although 替换；though 与although 都不能与but 并存，却能与yet 并存；as 引导让步状语从句时，倒装形容词、副词及无冠词的名词；只存在even though ，而无 *even although ；though 也可作连接性状语，而although 不可，如He said he would come; he didn ’t, though . ⑶ -ever 系列与no matter 系列的区别(见前) 9. 比较状语从句(见第一章，此略) 1 2
高考英语主语从句 定义：用作主语的从句叫主语从句，它是名词性从句之一。主语从句的时态：不受主句的时态影响和限制。引导主语从句的连接词有： 从属连词: that, whether； 连接代词: who (whoever), whom, whose, what (whatever)和which (whichever)； 连接副词: when, where, how和why。 连接词： 1. 从属连词：that，whether 1）that引导主语从句只起引导作用，在主语从句中不充当任何成分，that本身无实际意义，但不能省略。2）whether意为“是否”，放在句首句末皆可。由whether引导的名词从句做主语，表语，介词宾语，同位语时！不可用if代替。 a.That price will go up is certain. b. Whether they would support us was a problem. 他们是否会支持我们还是一个问题。 2. 连接代词who ，what ，which, whatever, whichever, whoever (Who, whom, which, what可以和ever构成合成词，和what一样引导从句，ever起到强调作用。此类主语从句不能用形式主语it引导，它们在句子中担任成分，不能省略，语序为陈述语序，既有疑问含义,又起连接作用,同时在从句中充当各种成分。 Which side will win is not clear. Whoever breaks the law will be punished. Whatever he did is right. Who killed the scientist remains a question. 1）What和that引导的主语从句的区别：that 只起引导作用，不充当任何成分，没有意思。What 不仅起引导作用，还要充当一定成分(主语、宾语或表语)，意思是：“什么”。 What we need is money. That he will come is certain. 2）whatever / whoever的用法（~ever=no matter ~---让步状语从句中） whatever / whoever可以引导主语从句,并在句中作主语、宾语、表语等,不含疑问意义。whatever相当于anything that; whoever 相当于anyone who。例如: Whoever(Anyone who) wants to enter into this school must take the exam. Whatever(Anything that) she did was right. 3. 连接副词when，where，how，why等。既有疑问含义,又起连接作用,同时在从句中充当各种成分。How this happened is not clear to anyone. When he will be back depends on the weather. When we’ll start tomorrow will be told soon. Where the test will be given is not yet decided. 4. 主语从句后置：为了避免主语冗长,句子头重脚轻,经常用it 作形式主语,主语从句放在后面作真正的主语. 例: That we shall be late is certain. -- It’s certain that we shall be late. 1）用it 作形式主语的结构 A. It + be + 形容词+ that 从句 (obvious, true, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.) 如：It is certain that she will do well in her exam. B. It + be + 名词词组+ that 从句(an honour, a fact, a pity, etc）如： It is a pity/shame that... 遗憾的是…… It is a surprise that…令人惊奇的是… It is a fact that… …是事实It is common knowledge that… …是常识 It’s a pity that we can’t go. C. It + be + 过去分词+ that 从句(said, reported, thought, expected, decided, announced, etc。）如：It is said that Mr. Green has arrived in Beijing. D. It + 不及物动词或短语+ that 从句( seem，happen, doesn’t matter ,turn out）。如： It happened that I was out that day. It doesn’t matter whether she will come or not. 2) 对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从
英语复合句的用法及解题技巧 在高考英语试题中，复合句占有较大的比例，复习时应该注意： １．倡发散思维，忌单向思维，考各种从属句，常常是不同类型的连接词语正误连缀而至，如果不抓住这一点，不从多方面思考选择，就容易以偏概全，误入歧途。 ２．弄清主从复合句中的每一个从属连接词的意思、用法、主句与从句在时态上的呼应、语气、是否需要倒装、固定搭配及逻辑常识等。 ３．熟记句型及特殊表达形式。 ４．注意各分句之间的特点及区别。 ５．注意有些连接词的省略情况及省略后某些语序发生的变化。 总之在做习题时，不能生搬硬套，一成不变，要全方位的思考，摸清出题者的意图，灵活机动，随着不同的语言环境而变化。 一、状语从句： 状语从句又可分为时间、地点、目的、原因、结果、行为方式、条件、让步及比较等几种形式。 １．I'll go with you as soon as I ____my work.

定语从句之关系词的选择 一、复习： 1.定语从句的定义:在复合句中，修饰某一名词或代词的从句叫做定语从句。 2.先行词：被修饰的名词或者代词叫做先行词。 3.关系词：引导定语从句的词叫做关系词。 4.关系词：关系代词：which,that,who,whom,whose 关系副词：when,where,why Eg. This is the book___________my father bought for me.（物，宾语） This is a book________has 199 pages.(物，主语) He is the man__________bought a book for me.（人，主语） The boy_________his father bought a book for is Bob.（人，宾语） The boy_________father bought a book for him is Bob.（人，定语） The book________color is red is Bob’s.(物，定语) The visited the town________I lived.(地点状语) They visited the town________I liked.(物，宾语) I will never forget the day_______Obama met Bao Zheng.(时间状语) I will never forget the time________I spent on campus.(物，宾语) That was the reason_______he gave me yesterday.(物，直接宾语) That was the reason________I began to learn photoshop.(原因状语) 关系代词和关系副词用法总结 关系词先行词关系词在定语从句中的成分which 物主语，宾语（可省略） that 人，物主语，宾语（可省略） who 人主语 whom 人宾语（可省略） whose 人，物定语 when 时间状语 where 地点状语 why 原因状语 二、关系词选择两步骤。 1.看先行词是人还是物。 2.看先行词在从句中所处的地位：主语，宾语，定语——关系代词；状语-----关系副词
