从句 分析结果A atomic bomb dropped on Hiroshima in 1945,after they

当然可以,一般情况下,介词+关系代词=关系副词,所以in which=where

1.which/that/不填
which/that代替先行词the islands,直接做定语从句中谓语动词visited的宾语,当然也可以省略不填.
(which/that) we visited last year
= the islands we visited last year
= we visited laat year the islands
2.where 或 on which
where = on which = on the islands,在定语从句中做地点状语.
where we stayed last year
= on which we stayed last year
= we stayed last year on which
= we stayed last year on the islands
3.when 或 in/during which
when = in which = during which,在定语从句中充当时间状语.
when we stayed together
= in/during which we stayed together
= we stayed together in/during which
= we stayed together in/during the days
4.which/that/不填
which/that等同于先行词the days,在定语从句中充当谓语动词spent的宾语.
(which/that) we spent together
= we spent which/that together
= we spent the days together
另：楼主要记住：关系代词可以直接换成先行词,然后在定语从句中充当名词性成分,如主语/宾语等；
关系副词等同于“介词 + 关系代词/先行词”,在定语从句中充当时间/地点/原因状语.

1unless 2beacuse 3 even 4on 5if 6 where 7 so that
8Tthough 9However 10Whether 11as 12Though 13as

in which 在这里是一个定语从句.
in which=where
你可以这样讲 many people were eaten by the shark in the scenes.许多人在这个情景下被鲨鱼吃了.
把这个句子放到一个定语从句中 要把介词in 提前.所以是in which many people were eaten by the shark.
你也可以说 Many people who saw the film were afraid to swim in the sea when they remmembered the scenes where people were eaten by the shark.
或者说可以改成两个句子,Many people who saw the film were afraid to swim in the sea when they remmembered the scenes.In these scenes many people were eaten by the shark.

　　此处的 affecting its operation 以及前面的 flashing on their consoles 都是动名词短语,不是分词.


　　本句中的 affecting its operation 是对 flashing on their consoles 进行补充说明的并列动名词短语,也就是说,第二个动名词短语 affecting its operation 前面省略了与上文重复的逻辑主语 a blue light.


　　a blue light continuously flashing on their consoles,和a blue light affecting its operation 都是动名词复合结构.动名词复合结构在书面语中,逻辑主语常用每次所用个（a blue light’s）,但在口语中,用作宾语的动名词复合结构的逻辑主语可以用主格代替.因此,如果罗嗦点儿说,这句话可以改写如下：




Some users complained about a blue light’s continuously flashing ontheir consoles,that is to say they complained about a blue light’s affecting its operation.(有些用户抱怨控制台蓝色信号灯不停地闪动,也就是说抱怨这种信号灯影响它自身的运行)

1.C
2. His mother will be sad if he doesn't pass the exam.
3. If he doesn't get up early enough, he won't be able to catch the early bus.
4. If they aren't at home, we won't visit them.
5. If we have a party, we will start at 7 p.m.
6. If I'm free, I'll go to feed the dogs with you.
7. If he dosn't come tomorrow, I'll go instead of him.
8. If you don't water the flowers, they will die.

这是一个固定句型A is to B what C is to D,意思是A对于B来说就像C对于D一样
此句话意思是古老的埃及人认为智力对于大脑就像视力对于身体（一样重要）

空里应该是The building where,这是一个地点状语从句

that,why 与 because 引导表语从句时的区别
虽然三者均可引导表语从句,但 that 没有词义,而 why 和 because 有自己的意思；另外,虽然 why和 because 都可引导表语从句,但前者强调结果,后者强调原因.如：
The reason was that you don’t trust her.原因是你不信任她.
The fact is that they are angry with each other.事实是他们生彼此的气.
He was ill.That’s why he was sent to the hospital.他病了,所以被送到医院来.
He was sent to the hospital.That’s because he was ill.他被送到医院,是因为他生病了.

是的.as引导的原因状语从句.您可能是对句义不理解,所以判断不出来.高中英语主要要掌握三大从句.
分别是：
1、定语从句（形容词从句）
2、名词词从句（包括主语从句,宾语从句,表语从句,同位语从句）
3、状语从句（副词性从句,包括时间,地点,结果,目的,原因等）

1.I was about to go to bed when I heard someone knock at the door.2.You would let your children play where you can see them.3.I was not kind to him when he was rude.4.If anything important happens,please call me up.5.In order that he could catch the bus,he got up early.6.He went out,though it was raining.7.His brother is as handsome as he (is).8.He stood up as if (he wanted ) to leave.9.It’s so good a book that I’ve read it again and again.

前面的朋友答案有错!请稍等!首先肯定：‘when’可以引导主语从句.前面的朋友搞错了!我对你句子分析后,提出的问题如下：1） 过多地受到汉语语句格式的影响,全句的句子安排一直在汉语语句格式的控制下进行的.2） ‘whe...

一般情况下,时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”,用“现在完成时”表示“将来完成时”.例如： I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话.（这是由as soon as引导的时间状语从句,从句中的谓语动词arrive是一般现在时,表示一般将来时,决不可用will arrive） As soon as I have finished this work, I will go home. 我一完成此工作,就回家.（从句中的谓语动词用现在完成时have finished,表示将来完成时,决不可用will have finished） If he comes back, please let me know.如果他回来了,请通知我.（从句中的谓语动词用comes back,表示一般将来时,决不可用will come back） 状语从句讲解和练习 状语修饰动词、形容词、副词或整个句子.通常由副词、介词短语、动词不定式、分词和从句等担当.例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语的位置比较灵活,可以位于句首、句末或句中.enough用作状语修饰形容词和副词时必须后置. 状语从句主要用来修饰主句或主句的谓语.一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式.尽管种类较多,但由于状语从句与汉语结构和用法相似,所以理解和掌握它并不难.状语从句的关键是要掌握引导不同状语从句的常用连接词 和特殊的连接词即考点.现分别列举如下: 1． 时间状语从句 常用引导词：when, as, while, as soon as, before, after, since , till, until 特殊引导词：the minute, the moment, the second, every time, the day,the instant, immediately , directly, no sooner … than, hardly …when, scarcely … when I didn’t realize how special my mother was until I became an adult. While John was watching TV, his wife was cooking. The children ran away from the orchard(果园), the moment they saw the guard. No sooner had I arrived home ,then it began to rain. Every time I listen to your advice, I get into trouble. 2． 地点状语从句 常用引导词：where 特殊引导词：wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories. Wherever you go, you should work hard. 3． 原因状语从句 常用引导词：because, since, as, for 特殊引导词：seeing that, now that, in that, considering that, given that. My friends dislike me because I’m handsome and successful. Now that everybody has come, let’s begin our conference. The higher income tax is harmful in that it may discourage people from trying to earn more. Considering that he is no more than 12 years old, his height of 1.80 m is quite remarkable. 4． 目的状语从句 常用引导词：so that, in order that 特殊引导词：lest, in case, for fear that,in the hope that, for the purpose that, to the end that The boss asked the secretary to hurry up with the letters so that he could sign them. The teacher raised his voice on purpose that the students in the back could hear more clearly. 5． 结果状语从句 常用引导词：so … that, such … that, 特殊引导词：such that, to the degree that, to the extent that, to such a degree that, He got up so early that he caught the first bus. It’s such a good chance that we must not miss it. To such an degree was he excited that he couldn’t sleep last night. 6． 条件状语从句 常用引导词：if, unless, 特殊引导词：as/so long as, only if, providing/provided that, supposing that, in case that, on condition that We’ll start our project if the president agrees. You will certainly succeed so long as you keep on trying. Provided that there is no opposition, we shall hold the meeting here. 7． 让步状语从句 常用引导词：though, although, even if, even though 特殊引导词： as(用在让步状语从句中必须要倒装),while ( 一般用在句首 ),no matter …, in spite of the fact that, while, whatever, whoever, wherever, whenever, however, whichever Much as I respect him, I can’t agree to his proposal. 尽管我很尊敬他, 我却不同意他的建议.

Sometimes we teach our children the way our parents have taught us. 10. 状语从句的简化 状语从句的省略 状语从句同时具备下列两个条件:①主句和从句的主语一致,或从句主语为it；②从句主要动词是be的某种形式.从句中的主语和be动词常可省略.例如： When ( the museum is ) completed , the museum will be open to the public next year . He’ll go to the seaside for his holiday if (it is ) possible. 另外,比较状语从句经常省略.例如： I’m taller than he (is tall ). The higher the temperature (is), the greater the pressure (is ). 就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行"简化".状语从句的"简化"现象在口语中较为普遍,而且在高考中的复现率也较高.因此,有必要对其进行全面、透彻的了解. 状语从句的"简化"现象常存在于以下五种状语从句中:①由if, unless等引导的条件状语从句;②由although, though, even if / though等引导的让步状语从句;③由when, while, as, before, after, until / till等引导的时间状语从句;④由as, as if等引导的方式状语从句;⑤由as, than等引导的比较状语从句.下面针对这五种情形作一归纳. (1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉.例如: If (it is) possible, he will help you out of the difficulty.如果可能的话,他会帮你摆脱困境. You must attend the meeting unless (it is) inconvenient to you.除非情况对你来说不方便,否则你必须出席这次会议. (2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉.常用于以下几种情形: a.连词+形容词 As (he was) young, he learned how to ride a bike.他小时候就学会了骑自行车. Whenever (she is) free, she often goes shopping.她有空就去逛商店. Work hard when (you are) young, or you'll regret.少壮不努力,老大徒伤悲. b.连词+名词 While (he was) a young boy, he was always ready to help others.他在孩提时代就乐于助人. Although (he was) a farmer, now he is a famous director.尽管他曾是个农民,而现在是位著名的导演了. c.连词+现在分词 As (she was) walking along the river bank, she was singing a pop song.她沿着河堤边走边唱着流行歌曲. Although (he is) doing his best in maths these days, he has still got no good marks.尽管近来他一直在学数学,但他仍然没有取得好成绩. d.连词+过去分词 He won't go there with us unless (he is) invited.除非受到邀请,否则他不会和我们一道去那里. The concert was a great success than (it was) expected.这场音乐会出乎意料地取得了巨大成功. e.连词+不定式 He stood up as if (he were) to say something.当时他站起来好像要说什么.He wouldn't solve the problem even if (he were) to take charge.即使他来负责,他也解决不了这个问题. f. 连词+介词短语 She looked anxious as though (she was) in trouble.她看上去很焦急,好像遇到了麻烦. He had mastered the English language before (he was) in the USA.他到美国之前就懂英语了. 注意:当从句主语和主句主语不一致时,从句部分要么用完全形式,要么用独立主格结构来表达.(=The meeting over,

习惯用法,放在前面为了强调对象,放在后面显得累赘!
例子：He is the professor to whom（不可以用who）I was talking then.
他就是在那时和我说话的教授.
也可以说：He is the professor who I was talking to then.
注意,有些情况介词不能够前置,比如固定搭配,不可拆散
例子：He is the professor who I was looking for.
此时for就不能前置

the old man sat there,reading the book.
the first time i met her,yuyue was standing in the wind,her long hair flying in the ai

你说的宾语从句吗?

从句是一个很麻烦的问题,如果你想了解,我还是建议你去买一本好一点的语法书,一般上面都有.（不要心疼money）
我给你写参考,不会太全面,可以勉强了解一下
分析引导词的句法作用以区别从句的种类
根据英语从句在句子中的句法作用,从句可分为三类：名词性从句,形容词性从句和副词性从句.通过对引导从句的各种引导词进行观察,我们不难发现,有的从句可以直接从引导词的形式和意义上来区分.如：Though the old man is over seventy, he still sees well and hears well. 我们一读此句,就可以认定,由Though引导的从句是一个让步状语从句.因为though只能引导让步状语从句,不能引导其它从句,但是有些引导词却能引导多种从句.如引导词when：既可以引导时间状语从句又可以引导定语从句,还可以引导名词性从句.此外,象that,where等,三类从句均可引导；who既可引导定语从句,又可引导名词性从句；so that 即可引导目的状语从句,又可引导结果状语从句……因此,这些形同义不同的引导词给我们理解、掌握、运用各种从句带来了很大困难.另外,搞不清楚从句在句子中所起的作用,就不能正确理解原文.那么,怎样正确区分各种形同义不同的引导词引导的从句呢?
1、 分析句子结构以区虽从句的种类 遇到一个复合句,首先要分析其句子结构,看从句在整个句子中起什么作用,那么它就是什么从句.
2、 分析引导词的句法作用以区别从句的种类 that这个词即是引导同位语从句,又可引导定语从句,这种两种从句从形式和结构上看特别相似,如何区分呢? 区分that引导的是同位语从句还是定语从句的方法是,看that在从句中是否充当句子成分,若that在从句中不充当任何成分,则为同位语从句；若that在从句中充当主语或宾语,则为定语从句.
3、 根据被修饰词来判断从句的种类 定语从句常常修饰一些具有实际意义的名词,如：the film；the student；the book；a house等等.而同位语从句常常修饰一些表示抽象概念的名词,如fact、idea、promise、truth等,用来说明这些名词所表示的具体内容.状语从句在句子中常用来修饰谓语动词.
4、 根据从句前词的词性来判断从句的种类 宾语从句分两种：动词的宾语从句、介词的宾语从句.宾语从句前肯定是动词或介词.定语从句是用来修饰名词或代词的,所以其前一定是一个名词或代词.
5、 根据上下文意义和结构形式上区分从句的种类 如so that即可引导目的状语从句,又可引导结果状语从句,如何区分呢?主要从以下两点来区分. ①根据上下文意义判断.“以便……”表示目的,是目的状语从句,“以致于……”,“结果……”表示结果,是结果状语从句. ②从结构形式上来分辨.so that前有逗号,为结果状语从句,反之,则为目的状语从句.有时,so that前无逗号,这里要看从句中有无can、could、may、might、will、would、should 等情态动词,如果有,则多是目的状语从句,若没有,则多是结果状语从句

一般用单数,但特指是可以用复数.

区分英语从句的“小窍门”
根据英语从句在句子中的句法作用,从句可分为三类:名词性从句,形容词性从句和副词性从句.通过对引导从句的各种引导词进行观察,我们不难发现,有的从句可以直接从引导词的形式和意义上来区分.如:Though the old man is over seventy,he still sees well and hears well.我们一读此句,就可以认定,由Though引导的从句是一个让步状语从句.因为though只能引导让步状语从句,不能引导其它从句,但是有些引导词却能引导多种从句.如引导词when:既可以引导时间状语从句又可以引导定语从句,还可以引导名词性从句.此外,象that,where等,三类从句均可引导;who既可引导定语从句,又可引导名词性从句;so that 即可引导目的状语从句,又可引导结果状语从句……因此,这些形同义不同的引导词给我们理解、掌握、运用各种从句带来了很大困难.另外,搞不清楚从句在句子中所起的作用,就不能正确理解原文.那么,怎样正确区分各种形同义不同的引导词引导的从句呢?
1、 分析句子结构以区虽从句的种类
2、 分析引导词的句法作用以区别从句的种类
区分that引导的是同位语从句还是定语从句的方法是,看that在从句中是否充当句子成分,若that在从句中不充当任何成分,则为同位语从句;若that在从句中充当主语或宾语,则为定语从句.
3、 根据被修饰词来判断从句的种类
定语从句常常修饰一些具有实际意义的名词,如:the film;the student;the book;a house等等.而同位语从句常常修饰一些表示抽象概念的名词,如fact、idea、promise、truth等,用来说明这些名词所表示的具体内容.状语从句在句子中常用来修饰谓语动词.
4、 根据从句前词的词性来判断从句的种类
宾语从句分两种:动词的宾语从句、介词的宾语从句.宾语从句前肯定是动词或介词.定语从句是用来修饰名词或代词的,所以其前一定是一个名词或代词.
5、 根据上下文意义和结构形式上区分从句的种类
①根据上下文意义判断.“以便……”表示目的,是目的状语从句,“以致于……”,“结果……”表示结果,是结果状语从句.
②从结构形式上来分辨.so that前有逗号,为结果状语从句,反之,则为目的状语从句.

引导让步状语从句的从属连词.主要的有although,though,even though,even if,while,however,whatever,whoever,whenever,wherever等.如：
Although [Though] he is poor,he is well contented.他虽穷却能知足常乐.
Though [Even though] it’s hard work,I enjoy it.尽管是苦活,但我乐意干.
Even if you don't like wine,try a glass of this.即使你不喜欢渴酒,也尝尝这杯吧.
While we don’t agree we continue to be friends.尽管我们意见不同,但我们还是朋友.
However you use it,it won’t break.不管你怎么使用,它都不会破.
Whatever you say,I believe you.无论你说什么,我都相信你.
Whoever telephones,tell them I'm out.不管是谁打电话,都说我出去了.
Whenever you come,you are welcome.你什么时候来,我们都欢迎.
However much he eats,he never gets fat.无论他吃多少,他都不发胖.

although / though / no matter +疑问词( 疑问词+ever) :：引导让步状语从句
1.Although/ Though he is young , he can help do a lot of housework
---Young as / though he is, he can help do a lot of housework
---Child as/though he is , he can help do a lot of housework
2.However difficult (=No matter how difficult ) it is , we may finish it in time.

这个嘛……这样来说吧：宾语从句在动词后边充当成分 标志：动词之后；例如：I like what my boyfriend gave me. like 之后就是整个宾语从句定语从句为修饰名词的 可以理解为“打扮” 主要做修饰、解释说明 被修饰...

时间状语从句(1)常用的连词有when, while, before, after, until(till),since, as soon as等. (2)时间状语从句中一般不用将来时,若谈论将来的事情,往往用一般现在时代替, 如：I’ll go on with the work when I come back tomorrow./As soon as he finishes the work, he will come to see me. (3)when和while都表示“当……的时候”,但有区别. when强调“特定时间”,如： There was a loud knock at the door when he was just falling asleep. while表示的时间是一段,而不是一点,如： While he was having supper, he heard someone knock at the door. while有时还有对比的含义,如： While I was reading, he was writing. 2.原因状语从句(1)常由because, since, as引导. (2)because表示直接的原因,着重点在从句,用于回答why,语气最强. I can’t go to school because I am ill. since一般表示对方已知的,无须加以说明的既成事实的理由,全句中心在主句,语气比because弱,常译为“既然”,如：Since you are ill, I’ll go alone. as表示十分明显的原因,一般说明因果关系,着重点在主句,语气较弱.常译为“由于”,如：As it is raining hard, we won’t go hiking. for是个并列连词,只能放在另一个并列分句后面,表示一种推理或解释,或用作附加说明,而不是指理由或原因,语气最弱,一般不放在句首,常译成“因为”,如：You haven’t met him, for he didn’t come here. 3.条件状语从句 常由if(假如、如果)No matter(不管)来引导,如：No matter what he says,I won’t believe him,如果主句是一般将来时,从句往往用一般现在时来表示将来,如：I’ll go for a picnic if it is fine. 4.结果状语从句 一般由so...that, such...that引导,如：It’s such a heavy box that nobody can move it. The box is so heavy that nobody can move it.

1/A
discover ：发现,指经过一定努力有目的地去找到,常用于发现未知的事物
find：偶然发现,不经意间
2/requesting=which requests
3/A who 在定于从句中作主语

伴随状语是指状语从句的动作伴随主句发生,它的特点是：它所表达的动 作或状态是伴随着句子谓语动词的动作而发生或存在的.
例如：
①He sat in the armchair,reading a newspaper. 他坐在扶手椅里读报.
②All night long he lay awake,thinking of the problem. 他整夜躺在床上睡不着,思考着那个问题.
伴随状语的判断
The dog entered the room, following his master.一般在分词短语 （现在分词表主动 过去表被动）前有逗号的是伴随状语.
伴随状语出现的条件
由一个主语发出两个动作或同一个主语处于两种状态, 或 同一个主语发出一个动作时又伴随有某一种状态.
伴随状语的逻辑主语
一般情况下必须是全句的生语,伴随状语与谓语动词所表示的动作或状态是同时发生的.
伴随状语可以有以下几种表示方法：
一、使用分词形式 The dog entered the room, following his master(这条狗跟着主人进了屋). The master entered the room, followed by his dog(主人进了屋,后面跟着 他的狗).
二、用 with 复合结构 The little girls were playing with snow with their hands frozen red(小女孩 们在玩雪,手都冻红了). The workers went out of work, talking and laughing all the way(工人们下 班了,一路有说有笑).
三、用独立主格结构 Last year I came here by climbing over the wall, sword in hand. The little boy goes to school, the little dog accompanying him every day(这小孩每天去上学,那条小狗陪伴着他).
四、用形容词 Crusoe went home, full of fear(克鲁索满怀恐惧地回家). Confident of the victory the players are fighting hard(运动员们对比赛夺胜 满怀信心奋力拼搏). The match will be broadcast live(这场比赛将作实况转播). He left home young and came back old(他少小离家老大回).
五、用名词 He went away a beggar but retuned a millionaire(他讨吃要饭离家,腰缠 万贯回归). He who had been twice prime minister of the country, died civilian(他曾两 度出任这个国家的总理,而死的时候却是一个平民).
六、用介词短语 The girl came back to her mother in tears.(这女孩眼泪汪汪地回到母亲身 边). How can you go to the wedding party in rags(你怎能衣衫褴褛地去参加婚 宴)? I went home out of breath(我上气不接下气地回家).
with 复合结构做伴随状语：
由“with ＋宾语＋宾补”构成的复合结构,在句中可作状语,表示伴 随.这一结构中的宾语补足语可由现在分词、过去分词、形容词、副 词或介词短语等来充当.
例如： 1．With production up by 60％,the company has had another excellent year．产量增涨了 60％,公司又是一个盈利年. 2．He soon fell asleep with the candle still burning．蜡烛还亮着,他很 快就睡着了. 3． She sat there alone with her eyes filled with tears． 他独自一人坐在那 儿,眼里充满了泪水.

独立主格结构做伴随状语：
独立主格结构是由一个名词或代词（作为该短语结构的逻辑主语） , 加上一个分词、形容词、副词、动词不定式或介词短语（作为该短语 结构的逻辑谓语）构成.该从属结构主要起状语作用,相当于一个状 语从句.故独立主格结构也可做伴随状语.
例如： 1．Mr.．Smith flew to New York this morning,his assistant to join him there this Saturday．今天早上史密斯先生坐飞机去了美国,他的秘书 星期六和他在那儿见面. 2．He was lying on the grass,his hands crossed under his head．他躺在 草地上,头枕双手. 3．He stood on the deck,pipe in mouth．他站在甲板上,嘴里叼着烟 斗.
分词短语做伴随状语：
现在分词短语和过去分词短语都可以做伴随状语, 现在分词短语表示 与主句的主语在逻辑上有主谓关系,即表主动意义；而过去分词短语 则表示与主句的主语在逻辑上是动宾关系,即被动意义.
例如： 1．“Can't you read?”Mary said angrily pointing to the notice．玛丽生气 地指着通知说：“难道你不识字吗?” 2．He sent me an e-mail hoping to get further information．他给我发了 一封电子邮件,希望得到更多信息. 3．He hurried to the hall,followed by two guards．他匆忙进了大厅, 后面跟着两个警卫.
形容词短语做伴随状语：
形容词短语做伴随状语时,通常表状态.
例如： 1．Full of apologies,the manager approached us．经理向我们走来, 嘴里不停地说着抱歉的话. 2．He was too excited,unable to say a word．他太激动了,一句话也 说不出来. 3．He stared at the footprint,full of fear．他盯着脚印,满心恐惧.
单个形容词做伴随状语：
单个形容词做伴随状语也表示状态,不表动作.
例如： 1．He sat there,silent．他一声不响地坐在那儿. 2．Breathless,she rushed in throughthe back door．穿过后门,他气喘 吁吁地冲了进来. 3．He went to bed,coldand hungry．他又冷又饿地上床睡觉了其实分词做伴随状语就是分词做方式状语的一种,伴随是一种方式.大多情况下 其实方式状语从句都等于伴随状语从句. 只有在 just) as…so…结构中位于句首, 这时 as 从句带有比喻的含义,意思是"正如…","就像",多用于正式文体
伴随状语的特点是：
它所表达的动作或状态是伴随着句子谓语动词的动作而发生 或存在的 1）现在分词与过去分词作状语的区别. 现在分词做状语与过去分词做状语的最主要区别在于两者与所修饰的主语的主 动与被动关系的区别. 1）现在分词作状语时,现在分词的动作就是句子主语的动作,它们之间的关系 是主动关系. ）过去分词作状语时,过去分词表示的动作是句子主语承受的动作,它们之间的 关系是被动关系.
比如 The teacher came in the classroom with handing a book in his hand. with handing 就是个例子 过去分词,现在分词 都可以做伴随状语,即在某件事情发生的时候相伴发生的 事情 这个句子 老师进入了教室,他是拿着本书进入教室的,在他进入教室的时 候他的手中有一本书（相伴）知道意思了吧.
做题的时候要注意区分什么时候使用过去分词和什么时候使用现在分词做伴随 状语.
一般的无非又几种情况：
过去分词表示一种完成了的 或者是被动意义的动作 分词作状语（关键找逻辑主语）
a)放在句首的分词往往看作时间状语 1 以及原因状语 2 1. Looking (when I looked) at the picture, I couldn't help missing my middle school days. 2.Seriously injured, Allen was rushed to the hospital. =As he was seriously injured, Allen was rushed to the hospital.
b)放在句中或句末常常看作为伴随状态(并列句) The girl was left alone in the room,weeping（crying ）bitterly. (但注意特殊：Generally/frankly speaking... / taken as a whole(总的来讲）不考 虑逻辑主语,看作为独立成分) C.difference between "being done"&"done" 1）being done---->"又被动,又进行” 2）done------->“又被动,又完成” 1）,2）均可作原因状语从句,而且更倾向于“done”,因为简单 eg.(being) deeply moved, she couldn't help crying. 但作条件(a),伴随状语只能用(b)2）,不能用 1） eg.(a)Once seen, it can't be forgotten./If asked so many questions, Mary's face will turn red. (b)she watched all the gifts ,greatly amazed.(=she watched all the gifts, and was greatly amazed 在一般句中：v1,and v2/ v1,v2,and v3) 结论： 当发现所要填非谓语为被动时, 能用"done"就用"done"(除了有先后顺序(用 (having done/having been done),详见 D) D.having done1)/having been done2)作状语时,分词的动作先于谓语动词 eg.1)Having handed in the paper, he left the room.(分词逻辑主语与主语相同, 用 having done) 2)Having been given a map, we found our way easily.(分词逻辑主语与主语不 同,是别人给的,用 having been done)

1.宾语从句
1）宾语从句可位于及物动词、介词和某些形容词后.连词that常可省略.介词后一般接疑问词引导的宾语从句.in that(因为),except that(除了),but that(只是）已构成固定搭配,其他介词后一般不接that引导的宾语从句.
*I promised that I would change the situation.
*All this is different from what American young people would say about friendship.
*He is certain that watching so much television is not good for children.

2)宾语从句后如有宾补,要用形式宾语it来代替,而把宾语从句移至宾补之后.
He has made it clear that he would not change his mind.
3)在think,believe,suppose,expect等动词后的宾语从句中,如果谓语是否定的,一般将否定词移至主句谓语上,宾语从句则变成肯定形式.
He didn't think that the money was well spent.
2.定语从句
定语从句所修饰的先行词可以是名词或代词,也可以是一个句子.定语从句通常位于先行词之后,由关系代词或关系副词引导.
*限制性定语从句
限制性定语从句修饰先行词,对先行词起修饰作用,紧接先行词之后,无逗号,若省去,原句意思不完整.引导定语从句的关系代词有who,whom,whose,which,that等.who,whom,whose用于指人,whose有时也可指物,相当于of which；which用于指物；that既可指人也可指物,但只用于限制性定语从句中.关系代词除了引导定语从句,替代先行词外,还在从句中担任主语、宾语、定语等.
The computers and cables which make up the Internet are owned by people and organizations.
Those who live alone or who are sick may have trouble in getting close to other people.
The girl whose parents died in an accident is living with her grandmother.

That is all that I've heard from him.
He's the first person that I'm going to interview this afternoon.
2)关系代词的省略
在从句中作宾语的关系代词常可省略.关系代词紧跟介词,作介词宾语时不可用that,只可用which或whom引导从句,并且不可省略,但当介词位于宾语从句句末时,作为介词宾语的关系代词仍可用that,也可省略.
This is one of those things with which we have to put up.
This is one of those things (whichthat) we have to put up with.
3)引导定语从句的关系副词有when,where,why等.关系副词在从句中作状语,意义上相当于一个“介词+which”的结构.
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.
No one knows the reason why(=for which) he was so angry that day.
*非限制性定语从句
非限制性定语从句既可修饰先行词,也可修饰整个主句,起补充说明作用,与主句之间有逗号隔开,若省去,原句意思不受影响.不可用that引导非限制性定语从句.关系词不可省略.
Every object has a gravitational pull,which is rather like magnetism.
*“介词+whichwhomwhose”引导的定语从句
“介词+whichwhomwhose”可引导限制性定语从句,也可引导非限制性定语从句,该结构中介词的选择取决于从句谓语动词的固定搭配,或先行词的习惯搭配.
This is the computer on which he spent all his savings
It is written by a person with whom we are all familiar.
*as引导的定语从句
as引导的定语从句主要用于“such...as”及“the same...as”的结构中,代替先行词是人或物的名词.as引导非限制性定语从句时,代替整个主句,从句可位于主句之前、之后或中间.

根据从句在句中的成分来判断.复合句是由两个或两个以上的有主谓结构的句子用从属连词连接起来的句子.其中一个句子是主体,叫做主句,而其他的句子叫做从句.从句由连接词引导,它们是:that,before,whether,if,although,because,as long as,as soon as,since,after,who,which,whom,what,whose,why,where,how,when,从句尽管有主谓结构,但不能单独成为一个句子,在句中,从句仅担任某个成分,根据担任的成分从句可分主语从句,宾语从句,表语从句,定语从句,状语从句.主语从句 在句中起主语作用的句子叫做主语从句.主语从句一般放在句首.引导主语从句的词有下列:that,who,whether,if,what,which,when,where,how,why.Who cleaned the blackboard is not known yet.谁擦的黑板还不知道.What he said is not true.他说的不是实话.That he'll come to see us is really great.他来看我们真是太好啦.It's very good that he has passed the exam.他通过了考试太好了.宾语从句 在句中起宾语作用的句子叫做宾语从句,宾语从句放在动词后面.引导宾语从句的词有下列.that,if,whether,what,which,when,where,how,why,I didn't expect that he had broken the glass.我没有想到他把玻璃打破了.Could you tell me who is your teacher?你能告诉我谁是你的教师吗?I don't know why he is absent.我不知道为什么他不在.表语从句 在句中起表语作用的句子叫做表语从句,表语从句放在系动词的后面.引导表语从句的词有下列.that,if,whether,what,which,when,where how,why等.The question is whether he will join us next time.问题是下次他是否跟我们一起干.That is why I am late.这就是我为什么迟到.定语从句 在句中起定语作用的句子叫做定语从句,定语从句放在被修饰的名词后面.引导定语从句的词有下列.who,whose,that,which,whom,when,where why.Do you know the man who is in the car.你认识坐在汽车里的人吗?This is the place where I was born.这就是我出生的地方.That is the reason why he lost his job.这就是他为什么失去工作的原因.状语从句 在句中起状语作用的句子叫做状语从句,状语从句一般放在句后,强调时放在句首.He opened the windows since it was hot.由于天气热,他打开了窗户.When he was young,he couldn't go to school.他年青的时候没能上学.I'll let you know as soon as he come back.他一回来我就告诉你.定语从句相当于形容词,用来修饰名词或代词.宾语从句相当于一个宾语,用作名词.状语从句相当于句子中的一个状语,或副词,指时间、地点和原因等.虽然它们意义不同,但用法大致相同,都要用陈述语序,都要有连接词

选B 这是典型的定语从句 先行词是 the city 后半句your parents visited last winter 是不完整的句子 缺少的正好是city 即 your parents visited the city last winter 所以应该用which

条件状语从句
条件状语从句就是用以表示“在某种条件下,会……”
常用if ,in case , on condition等词来引导
连接词主要有 if, unless, as/so long as, on condition that 等..
if 引导的条件句有真实条件句和非真实条件句两种.
主句用一般将来时,if或unless引导的条件状语从句用一般现在时.
固定搭配
unless = if not.
Let's go out for a walk unless you are too tired.
If you are not too tied, let's go out for a walk.
真实条件句,
如：If it rains tomorrow, we won”t go on a picnic.
非真实条件句是虚拟语气的一种,表示与事实相反,如：
If I were you, I would go with him.
if wrless,on condition that
so/as long as只要
时间状语从句
时间状语从句
（adverbial clause of time）
1.由when, while, as引导的时间状语从句.例如：
When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候,你就是在开始知道一些事物了.
When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候,它在生长,它感到压抑,它蓄存着这么一种爆炸性力量,一旦冒出,它就会炸破一切!

You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候,你就能感觉到空气在流动.
Our headmaster laughed as she spoke.我们的校长边谈边笑.
【区别】when, while和as的区别：when引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词.并且when有时表示“就在那时”.例如：
When she came in, I stopped eating.她进来时,我在吃饭.(瞬时动词)
When I lived in the countryside, I used to carry some water for him.当的住在农村时,我常常为他担水.（延续性的动词）
We were about to leave when he came in.我们就要离开,就在那时他进来了.
While引导的从句的谓语动作必须是延续性的,并强调主句和从句的动作同时发生（或者相对应）.并且while有时还可以表示对比.例如：
While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词,was reading和was watching同时发生)
I like playing football while you like playing basketball.我喜欢踢足球,而你喜欢打篮球.（对比）
As表示“一边……一边”,as引导的动作是延续性的动作,一般用于主句和从句动作同时发生；as也可以强调“一先一后.例如：
We always sing as we walk.我们总是边走边唱.（as表示“一边……一边”）
As we was going out, it began to snow.当我们出门时,开始下雪了.（as强调句中两个动作紧接着先后发生,而不强调开始下雪的特定时间）
2.由before和after引导的时间状语从句.注意before引导的从句不再用否定式的谓语,并且当before引导的从句位于主句之后,有时译成“就,才”.还要注意主句和从句之间的时间关系.当主句用将来时,从句总是用现在时；如果before引导的从句谓语用的是过去时,则主句动词多用过去完成时,这样以便体现动作发生的先后.After表示主句动作发生在从句动作之后.主句和从句的动作的时间关系正好与before引导的从句相反.例如：
It will be four days before they come back. 他们要过四天才能回来.
Einstein almost knocked me down before he saw me.爱因斯坦几乎把我撞倒才看到我.
My father had left for Canada just before the letter arrived.我父亲恰好在信到之前去加拿大了.

After you think it over, please let me know what you decide.你仔细考虑过以后,告诉我你是怎样决定的.
After we had finished the work, we went home.完成工作之后,我们回家了.（从句用过去完成时,主句用一般过去时）
3.由till或until引导的时间状语从句.till和until一般情况下两者可以互换,但是在强调句型中多用until.并且要注意的是：如果主句中的谓语动词是瞬时动词时,必须用否定形式；如果主句中的谓语动词是延续性动词时,用肯定或否定形式都可以,但表达的意思不同.例如：
I didn't go to bed until（till） my father came back.直到我父亲回来我才上床睡觉.
It was not until the meeting was over that he began to teach me English.直到散会之后他才开始教我英语.
I worked until he came back.我工作到他回来为止.
I didn't work until he came back.他回来我这才开始工作.
Please wait until I arrived.在我到达之前请等我.
4.由since引导的时间状语从句. since引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词.一般情况下,从句谓语动词用一般过去时,而主句的谓语动词用现在完成时.但在It is ＋时间＋since从句的句型中,主句多用一般现在时.例如：
I have been in Beijing since you left. 自从你离开以来,我一直在北京了.
Where have you been since I last saw you? 自上次我和你见面以后,你到哪里去了?
It is four years since my sister lived in Beijing. 我妹妹不在北京住有四年了.
It is five months since our boss was in Beijing.我们老板离开北京有五个月了.
5.由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等引导的时间状语从句.这些连词都表示“一……就”.例如：
I will go there directly I have finished my breakfast. 吃完早饭,我立即到那里去.
The moment I heard the news, I hastened to the spot.我一听到消息,马上赶到了出事地点.
As soon as I reach Canada, I will ring you up. 我一到加拿大,就给你来电话.
【注意】hardly(scarcely, rarely)…when / before, no sooner…than相当于as soon as之意.主句用过去完成时,从句用一般过去时.当hardly, scarcely, rarely和no sooner位于句首时,主句应用倒装语序.例如：
He had no sooner arrived home than he was asked to start on another journey. 他刚到家,就被邀请开始另一旅程.
No sooner had the sun shown itself above the horizon than he got out of bed to commence work.太阳刚从地平线上升起,他就起床劳动去了.
Hardly had I sat down when he stepped in.我刚坐下,他就进来了.
He had hardly fallen asleep when he felt a soft touch on his shoulder.这个阿拉伯人刚要入睡就感到肩膀上被轻轻一触.
6.由by the time引导的时间状语从句.注意时态的变化：在一般情况下,如果从句的谓语动词用一般过去时,主句的谓语动词用过去完成时；如果主句的谓语动词用一般现在时,主句的谓语动词用将来完成时.例如：
By the time you came back, I had finished this book.到你回来时,我已经写完这本书了.
By the time you come here tomorrow, I will have finished this work. 你明天来这儿的时候,我将已经完成此工作了.
7.由each time, every time和whenever引导的时间状语从句.例如：
Each time he came to Harbin, he would call on me. 他每次来哈尔滨,总是来看我.
Whenever that man says“To tell the truth”, I suspect that he's about to tell a lie.每当那个人说“说实在话”的时候,我猜想他就要说谎了.
You grow younger every time I see you. 每次遇到你,见你更年轻了.
8.由as long as和so long as引导的时间状语从句.这两个连词表示“有多久……就多久”.例如：
You can go where you like as long as you get back before dark. 你可以随意到哪里去,只要在天黑以前回来就行.
I will fight against these conditions as long as there is a breath in my body! 只要我一息尚存,我就要反对这种境况.
这是一般现在,一般过去,现在进行,过去进行,现在完成,过去完成,现在完成进行,一般将来,过去将来时的时间状语:
1.Often,usually----------动词原型do,does,am,is, are
2.yesterday,last Sunday,in the past-------动词过去式did,was,were
3.now--------be+doing
4.while,at that time,-------was doing,were doing
5.since从句,for 2 days,------have done,have been
6.by+过去的某个时间点----had done,had been
7.与现在完成相似-------have been+持续动词ing形式
8.一切表示将来的时间状语,in+一段时间-------将来要发生的一般性动作,
will,shall+原型
9.与一般将来时相似-----------would+原型

你的采纳是我们答题的动力,

teachers request we should go to school on time

我简单地回答,不明白再问吧.
宾语从句：my teacher said that we should finish our homework first.
主语+谓语动词+that从句作为宾语
定语从句：he is an old man who has a little dog.
句子成分齐全he is an old man；先行词是man,引导词是who,who 引导的定语从句是修饰man,告诉我们这个man是有着一条小狗的man.
根据先行词的不同,还可以用that,which,where等词引导.
状语从句：i will go to the park,when it stops raining.
状语一般是说明时间、地点、条件、原因、目的等

however
意思是无论多么难

Nobody knows the reason that Matt refused to go to the party这句话是错的,应该用why替代that.需要注意的是that是关系代词,在引导从句（定语从句)的时候必须在从句中作成分（主语、宾语）,而诸如where,when,why这些是关系副词,在从句（定语从句）中作状语.所以在选择连接词引导从句的时候关键看从句中缺什么,比如题目中Nobody knows the reason （ )Matt refused to go to the party,（ )Matt refused to go to the party是reason的定语从句,从句是完整的,是一个主+谓的基本机构,缺状语,所以只能选关系副词,reason表示原因,所以选why,假如这个句子变成Nobody understands the reason （ )Matt give to us.那么从句中缺宾语（间接宾语）,所以应该选连接代词that,或者省略.

efore 是在..之前,所以主句用的是过去完成时,从句用一般过去时
可翻译为：“数周过去后我才意识到这幅画丢了.”
when 是当...时 应用相同时态吧

1.名词性从句（在句子中起名词性作用,如主语从句,表语从句,宾语从句,同位语从句）；
2.定语从句（在复合句中起定语作用,修饰名词或名词性短语等名词性结构）；
3.状语从句（在复合句中起状语作用,一般由连接词引导,修饰动词、形容词或副词）.

1.It is funny that _your dog can watch TV.______________________________
2.It worried us that _the English teacher didn't come to class this morning.____________________________
3.It appears that _you have had a fever,_______________________________

差别在于这个从句在整个句子中充当的成分,做什么成分就叫什么从句.关系词或代词的作用就是引导这些从句.
主语从句 充当 主语成分,如：（What caused the accident） remains unknown.其中What caused the accident就是主语从句.
最常见的主语从句是形式主语it句型,如It is certain that he will win the match.
以此类推,表语从句His suggestion is（ that we should stay calm.）
宾语从句I don’t know（ if there will be a bus any more.）
状语从句I will call you （as soon as I arrive in Beijing.）
定语从句He lives in a room （whose window faces south.）

We can find (that) there are many different teams who play this football.（that被省略）
who play this football 是teams的定语从句.
你感到奇怪是因为teams在这里做先行词,可以指队伍也可以指队员.
所以翻译一下是：我们看到这里有很多不同队伍的队员在踢足球.
希望解决了你的疑惑.

我教你个办法你就好记了
where = in which
所以live后不再加 in
但是如果是Which引导的句子
那麼就要加in
where you live yet=which you live in yet

1.B 2.C 3.C 4.A

whatever 和 no matter what 在基本词义上是一致的,都是无论什么的意思.
但是 whatever 和 no matter what 区别就是 whatever 可以充当名词成分（比如主语,宾语等）.而 no matter what 不行,它只能引导让步状语从句.

你用的是鲁教版的教材吧?我们刚刚复习过 都是准确的答案
似乎是UNIT1和2的呢 呵呵

1.主从句的时态一般是一致或配套使用的,大部分情况有规律可循,但要看主从句间的逻辑关系以及表达的实际情况来定,而且这并非一成不变,不是看主句是什么时态就能判断从句是什么时态的.比如说,主句用一般过去时说“我在街上看到了杰克”,结果状语从句可以用一般过去时表达“所以我没有给他打电话了”,也可以用一般将来时说“所以我明天不会再去找他了”；时间状语从句可以是过去进行时“当我正在赶往邮局的时候”,也可以是过去完成时“当我已经把邮件寄出去了”.所以,总而言之,看表达的内容是什么时间和逻辑关系来定时态这才正确.
2.个人认为选两者都可以,意思的侧重有所不同而已.
3.so that 引导结果状语从句时,没有规定说必须要用情态动词,还是和表达的意思有关.比如：
Everyone lent a hand,so that the work was finished ahead of schedule.
每个人都帮了忙,所以工作提前完成了.

one of the men held the view that what the book said was right.
我先把这个句子的结构分析一下
one of the men【主语】 held 【谓语】the view【宾语】 that what the book said was right【同位语从句】
在同位语从句中what the book said【主语从句】 was right【系表结构作谓语】
在这个句子里,其实是同位语从句中套了一个主语从句.what是充当主语从句的引导词.主语从句一般是由that,whether,who,what,whatever等引导,所以这里不能用which,只能用what

完整的应该是which I believe (that it) will help, which引导定语从句修饰advice,定语从句里还套了一宾语从句,省略了that it.希望你能懂.

句子对.
when后he可要可不要,省略掉是因为后面主句（he tries to make money from it）
的主语也是he,避免重复.

B!因为从句中缺主语,而不是缺地点状语,所以用关系代词that或which,而不是用关系副词where!这道题是毫无疑问的!我是英语老师,有不懂再可以问.
