状语从句的转换正确转换状语从句的句子结构
状语从句的转换正确转换状语从句的句子结构状语从句的转换：正确转换状语从句的句子结构状语从句是复合句中的一个从句，用来修饰主句中的动作、状态或程度。
在句子中起到状语的作用。
为了使句子更加清晰和简洁，我们可以尝试将状语从句转换成其他形式。
本文将介绍状语从句的转换技巧和正确的句子结构，帮助读者更加灵活运用这一句子成分。
一、将状语从句转换成独立结构状语从句转换成独立结构是指将整个状语从句改写为一个副词、介词短语或分词短语，使其与主句并列表达。
下面是一些具体的转换方法：1. 将时间状语从句转换成介词短语：原句：When the sun sets, the sky turns red.转换后：At sunset, the sky turns red.2. 将条件状语从句转换成介词短语：原句：If it rains tomorrow, we will stay at home.转换后：In case of rain tomorrow, we will stay at home.3. 将原因状语从句转换成介词短语：原句：Because it was raining, we stayed at home.转换后：Due to the rain, we stayed at home.4. 将目的状语从句转换成不定式短语：原句：I study hard so that I can pass the exam.转换后：I study hard to pass the exam.5. 将方式状语从句转换成独立结构：原句：She walked as if she were in pain.转换后：She walked with apparent pain.二、将状语从句转换成其他从句除了将状语从句转化为独立结构外，还可以将其转换成其他从句形式，如不完全倒装、倒装、强调等。

英语中的几种省略现象
英语中的几种省略现象，这样分类学起来简单多了！英语中有时为了避免重复，使语言简练紧凑，在不损害句子结构的前提下，往往省去一个或多个句子成分，这种语法现象称为省略。
1简单句中的省略简单句中的省略，在口语中最为常用，可省略主语、谓语、主语和谓语的一部分、宾语等。
例如：a. (It) Sounds like a good idea.b. (Is there) Anything else?2并列句或并列结构中同等句子成分的省略在并列句或并列结构中，如果前后两部分有同等句子成分，为避免重复，同等句子成分可以在一处省略。
例如：a. Mary is tall and (she is) beautiful.b. I can’t decide whether to go to the library or not (to go to the library). 3状语从句中的省略1. 在时间、条件、让步等状语从句中，若从句的主语和主句的主语相同且从句中的谓语动词含有be动词，可以省略从句中的主语和be动词。
例如：Unless (I am) invited, I will not go to your birthday party.2. 在if it is possible, when it is necessary等类似结构中，it is常可省略。
例如：If (it is) possible, Lisa will do a part-time job.4定语从句中的省略当关系代词that，which等在限制性定语从句中充当宾语且不位于介词之后时，关系代词可以省略；in which或that在先行词way后时可省略。
例如：a. Is the book (that / which) you’re reading interesting?b. This is the way (in which / that) your parents love you.5不定式符号to的省略1. 在感官动词(see, hear, feel等)和使役动词(have, make, let等)后作宾语补足语时，不定式符号to需省略。
英语中的省略
英语中的省略为了避免重复，英语句子中某些部分可以省略。
常见的省略有以下几种：一、状语从句中的省略在时间、条件、让步及比较状语从句中，如主句和从句主语一致（或从句主语是it），且从句含be动词时，可将从句中的主语和be动词省略，从而构成“连词+ 分词/形容词/副词/介词”结构。
这里常见的连词有when/while/as/if/unless/once/although/though/than等。
When (water is )heated, water is turned into vapor. 水加热时变成气体。
He works very hard though（he is）rather weak. 他尽管体弱，但他十分努力地工作。
He came earlier than（he had been）expected. 他来得比预料的要早。
考例：①The research is so designed that once ____ nothing can be done to change it.A. beginsB. having begunC. beginningD. begun②If you go to Xi' an, you will find the palaces there more magnificent than commonly ___ .A. supposingB. supposedC. to supposeD. suppose分析：①D。
once后省略了the research is begun ②B。
比较状语从句中的完整形式是：than they are commonly supposed。
二、并列结构的省略1.并列结构一般由and, or, but等连接，他们可以连接单词、短语或分句，其中相同成分出现时可以被省略。
One of the sides of the board should be painted yellow, and ____.A.the other is whiteB. another whiteC. the other whiteD. another is white选C。
时间状语从句和省略
时间状语从句和省略一、时间状语从句1. 某些易用错的连词。
(1) 连词immediately / directly / instantly和词组the moment, the minute意为“一……就……”，相当于as soon as。
如：The thief ran away the moment / directly he saw the policeman.[注意]a. immediately / directly / instantly也是副词，在句中作状语。
如：I didn’t immediately realize how serious the situation was.b. 介词on / upon +名词/ V-ing也表示“一……就……”。
如：Yao Ming was surrounded by the media on his arrival at the airport.On seeing the painting by Van Gogh, I fell in love with it at once.(2) 词组the first time, the last time, each time, every time以及by the time，都引导时间状语从句。
如：The first time I spoke English before foreigners, I was a student of high school.Every time I meet the policeman at that crossroads, he will give me a big smile.[注意] for the first time是介词短语，意为“第一次……”，常用来作状语。
They had a face-to-face talk for the first time.(3) when, while和as引导时间状语从句的区别：when引导时间状语从句时，可与短暂性动词连用，也可与延续性动词连用；而while只能与延续性动词连用；as表示两个动作的同时性，意为“一边……，一边……”。
一篇彻底搞懂时间状语从句
在中考英语中，状语从句是初中英语中很重要的语法项目，是学英语学习的重点更是教与学的难点。
状语从句根据它表示的意思可分为时、原因、条件、目的、结果、让步、比较狀语一般由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语来担当。
其位置一般放在句末，但也可放在句首或句中。
副词是一种用来修饰动词, 形容词 , 副词或全句的词, 说明时间 , 地点 , 程度 , 方式等概念。
1.副词一般在句子中做状语 .He speaks English very well.他英语说得非常好. （中的 very 是程度副词，用来修饰well 。
very well 是修饰 speak 的程度状语）He is playing under the tree.他在树下玩儿. （ under the tree 是地点状语. ）2.不定式在句子中可以作目的状语。
I come specially to see you.我专门来看你.3.介词短语Ten years ago, She began to live in Dalian.The boy was praised for his bravery.4.从句作状语When she was 12 years old, she began to live in Dalian.If I am not busy tomorrow, I will play football with you.5.分词作状语Having had a quarrel with his wife, he left home in a bad temper.Inhibited in one direction, it now seems that the Mississippi is about to take another.中考主要考查引导状语从句的连词、从句时态等方面。
重点考查时间状语从句、条件状语从句、结果状语从句和比较状语从句。
英语省略句的用法
省略句的基本情况总结省略句的基本情况分为以下三个方面：1。
为避免重复而进行的省略。
当一个句子中有两个或更多相同的词、短语出现时，其中的第一个须保留,其余的往往省略,以达到避免重复、使句子简练的目的。
高考中尤其要注意的情况是:当时间状语从句、地点状语从句、方式状语从句、让步状语从句、条件状语从句等状语从句中的主语与主句的主语一致并含有be时，往往将该状语从句中的主语和be一同省略。
例如：He hurt himself while （he was）playing basketball。
他在打篮球时受了伤。
// He works very hard though (he is）still rather weak。
他虽然身体还很虚弱，但他非常努力地工作。
2.语法上的省略.有些成分的省略是出于语法上的原因—-使表述更为简明,例如: He got up at six (o'clock).他六点钟起床.// He is twelve （years old）。
他十二岁.// I walked （for) ten miles。
我走了十英里路.3.习惯用法上的省略。
有些省略句的情况是出于习惯用法,尤其是在口语中.例如,在问句中be常常省略，有时连主语一起省略: Very easy？很简单吗？// Feeling unwell？感觉不舒服吗？又如以what，how或why开头的某些问句：What (happened) next？下面要发生什么？// Why not？为什么不？// Why so?为什么这样？［考题1］He has made a lot of films，but ____ good ones。
A。
any B。
some C。
few D。
many［答案］C[解析］下划线处之前的but决定了只能选择具有否定含义的选项C。
题干中的“few good ones”为省略句形式，单独看起来不好理解，应联系上文理解为“He has made few good films。

按照语法的分析，句子应该具备的成分，有时出于修辞上的需要，在句中并不出现，这种句子叫做省略句，这种语法现象称为“省略”。
二、特点虽然省去句子语法构造所需要的组成部分，但仍能表达其完整的意义。
省略形式多样，从单词、短语到分句，都可以省略。
三、简单句中的省略1.省略主语和谓语—Hello! Is Jack in?—（This is）Jack speaking.—How are you?—（I’m）Fine, thank you.2.There be句型中（Is there）Anything else that you want?3.感叹句根据上下文的省略How beautiful（it is）!4.名词所有格后的名词，如果是表示住宅、店铺、教堂或上下文已经暗示或明确指出过的事物时，常省略。
I’m going to the tailor’s（shop）.四、并列句中的省略1.如果后面分句中有与前面相同的部分常被省略。
She is not fond of cooking, nor am I（fond of cooking）.2.有时并列句中的省略部分出现在前面的分句中时，要看完最后一个分句才能掌握全句的完整意义。
Tom lives（in London）, and John works in London.五、复合句中的省略1.宾语从句中的省略（1）由特殊疑问词引导的宾语从句中，若有与前面主句重复的内容，则可将重复内容省略，而只保留特殊疑问词。
You look upset. Can you tell me why?（2）在I think/I believe/I hope/I guess/I’m afraid等作答句，后面跟“so”与“not”分别等于肯定或否定时，宾语从句可省去。
—Do you believe he will pass the exam?—I believe so.（=I believe he will pass the exam.）—Do you think it will snow?—I hope not.（=I hope that it will not snow.）（3）在know/think/consider/suppose/find/believe/say/decide等动词后面所接的宾语从句中，连词that可以省略；若带有多个宾语从句，只有第一个that可以省略，其余的则不能省略。
状语从句中的省略
※状语从句中的省略在表示条件、方式、时间、让步的状语从句中，如其主语与主句的主语一致或是代词it，且谓语动词中又有be时，则从句中的主语和be都可以省略。
1．比较状语从句中的省略在以than或as引导的比较状语从句中，如果主语与主句的主语一致，则从句主语与谓语（可以是be动词，也可以是行为动词）均可省略；如果从句的主语和主句的主语不一致，则省略其谓语及与主句相同的部分。
如：Production is going up much faster than (it was) before.生产比以前增加得快多了。
Jane can speak Spanish more fluently than Peter (can speak).珍妮讲西班牙语比彼得讲得流利。
Winter in Guangzhou is not so cold as in Beijing.广州的冬天不像北京的冬天那么冷。
I shall come as early as possible.我会尽快来。
在口语中，than和as及其后的部分可以省略。
I have never seen a more beautiful garden (than this).我没见过更漂亮的花园。
I would rather go with you (than stay here).我宁愿跟你一起去。
Are they as keen about it (as we are)?他们对这件事和我们一样这么迫切吗？2．条件状语从句中的省略在条件状语从句中，与主句中相同的部分可以省略。
例如：I am happy if you are (happy).如果你高兴，我也高兴。
If (it is) necessary, I will ask you for help.如果有必要，我将请你帮忙。
[注] 在条件状语从句中，经常使用一些省略了的固定搭配，如：if any, if necessary, if possible, if so, if not, 或if + 介词短语，if/unless/once + 过去分词等。
高中英语语法之省略
高中英语语法之省略英语中省略现象较为普遍，对省略的考查已成为高考中的热点。
句子成分的省略，可分为以下几种情况：为了使话说得简明扼要，英语句子中某个单词、短语甚至从句或主句都能够省去。
Ⅰ、状语从句中的省略用法一、如果从句的主语和主句的主语一致，且从句的谓语含有be动词的某种形式（am/is/are/was/were），可同时省略从句的主语和be动词的某种形式。
1、when，while引导的时间状语从句e.g. Do be careful when (you are) crossing the street.When/While (I was) on my way to work, I met her.2、if，unless，once引导的条件状语从句e.g. If (it is) properly treated, waste will do no harm to the environment.I’ll not go to the party unless (I am) invited.Once (you are) caught stealing in a supermarket, you will be punished.3、though，although，whether，no matter whether/what/how/who等引导的让步状语从句e.g. He was happy, though/although (he was) poor.Whether (she is) sick or well, she is always cheerful.No matter how/However hard the task (is), we must fulfill it in time.（注：从句的主语和主句的主语不一致时，只省略从句中的be动词形式）4、as if，as though引导的方式状语从句e.g. He rubbed his eyes and yawned as if/though (he was) waking up after along sleep.He stood up as if/though (he wanted) to leave.（as if/though + to do表示一个将来的动作）二、than，as引导的比较状语从句中的省略用法：当不同的主语实行比较时，一般省略从句中的谓语；当从句中的主语与谓语（be动词除外）和主句中的主语与谓语相同时，通常省略从句中的主语和谓语，只保留比较部分。
