状语从句的省略与强调句型
状语从句的省略与强调句型状语从句是英语中常用的一种句子结构，它可以在句子中充当状语，用来修饰动词、形容词、副词等。
在使用状语从句时，有时可以省略部分成分，从而使句子更简洁明了。
同时，通过加入强调句型，我们可以突出状语从句中的重要信息，提高表达的效果。
本文将探讨状语从句的省略与强调句型。
1. 状语从句的省略在英语中，状语从句可以根据情况省略主语、谓语、宾语等成分，以简化句子结构。
状语从句的省略主要体现在时间状语从句、地点状语从句和条件状语从句中。
1.1 时间状语从句通常情况下，时间状语从句与主句之间存在一个连词，如when （当）、while（当...的时候）、after（在...之后）、before（在...之前）等。
但是，当主句中的谓语动词为延续性动词（继续进行的动作或状态）时，时间状语从句的连词和主句的谓语动词可以省略。
例如：- He was reading a book when I arrived.（当我到达时，他正在看书。
）- He was reading a book I arrived.（当我到达时，他正在看书。
）1.2 地点状语从句地点状语从句表示行为发生的地点，通常使用连词where（在哪里）、wherever（无论在哪里）等引导。
然而，在某些情况下，地点状语从句可以省略引导连词where。
例如：- He lives in the house where he was born.（他住在他出生的房子里。
）- He lives in the house he was born.（他住在他出生的房子里。
）1.3 条件状语从句条件状语从句表示主句发生的条件，通常使用连词if（如果）、unless（除非）等引导。
有时，在条件状语从句中的谓语动词是be动词时，可以将if省略。
例如：- If it rains tomorrow, we will stay at home.（如果明天下雨，我们会待在家里。
（完整版）时间状语从句
（完整版）时间状语从句时间状语从句讲练一．概述概念：在复合句中，由时间连接词引导的表示时间的状语从句叫做时间状语从句。
(在复合句中，要注意主句和从句的时态大多都要保持一致。
）一般来说，时间状语从句常由连词when, before, after, as soon as或until等引导。
在使用时，从句一般不用一般将来时态。
若主句为一般将来时态或是含有将来的意味时，时间状语从句常用一般现在时态来代替将来，即“主将从现”。
如：I will go to the cinema as soon as I finish my homework. 我一完成作业就去电影院。
When I grow up, I will join the army. 当我毕业了，我就要去参军。
二．常用连接词举例1. when连接的时间状语从句when相当于汉语的“当……时候”。
如：When the weather is fine, many families go out for a walk.天气好时，很多家庭都出去散步。
When I got home, I found mother cooking for me.我到家时，发现妈妈在为我做饭。
I always go to see the doctor when I do not feel well.我感到不舒服时总要去看医生。
Please let me know when you have trouble.有因难时请告诉我。
2. before/after连接的时间状语从句before表示“在……之前”，after表示“在……这后”。
如：He telephoned that he couldn’t come before the concert began.他打电话来说音乐会开始前来不了了。
Mother always prepares supper before I come back from school.妈妈总是在我放学回家前把晚饭准备好。

状语从句中的省略

现就把各种状语从句的省略现象列举如下：一、时间状语从句中的省略When (she was）very young, she began to learn to play the piano. 她很小时，就开始学习弹钢琴。
While （I was) at college, I began to know him，a strange but able student。
我在上大学时就开始认识他，一个奇怪但有能力的学生。

英语句子中的省略
英语句子中的省略一省略句的概说省略句是我们在学习英语过程中能不断体验收获和趣味的一种惯用手法，无论是说话还是写作，都要求生动活泼，简明扼要。
按照语法的分析, 有时句子应具备的成分出于修辞上的需要, 会缺少一个或几个句子语法结构所必要的语言成分，但在一定语境中可独立存在，仍能表达其意义完整并发挥交流功能的句子则被称为省略句。
省略的结果不仅能使句子结构更加精练，而且可起到连接上下文并使相邻词语达到强调的作用。
英语省略句用词简练, 表意简练, 往往收到一定的修饰效果, 句中的某些成分因上下文已提供了充分明确信息或前文已出现过的某些成分，为了避免不必要的重复，也不会引起言语上的误解，并可突出中心词，从而使整文紧密连接的一种修辞手法，其语法现象就是省略。
举个例子：Glad to see you. 这是个简单句，主语I和谓语am可以省略。
省略的形式从单词、短语到分句等都可省略, 而且各有其一定的衔接关系。
二省略句的分类（一）句中成分的省略1. 主语的省略Beg your pardon. （我）请你原谅。
（Beg前省略了主语I）Come on! 得了吧（你）！（Come前省略了主语You）2. 谓语的省略John is a lawyer，his wife (is) a cleaner.Some of us study Japanese，others (study) English.3. 表语的省略She was a lover of sports as she had been in her youth..（had been后面省略了a lover of sports）4. 宾语的省略Let’s do the cases. I’ll read and you’ll type.（read和 type 后面省略了宾语cases）5. 定语的省略I spent part of the money, and the rest I gave.（the rest后面省略了定语of the money）6. 状语的省略She wasn’t cry. Strange! （Strange前面省略了状语how）7. 词的省略1）名词、冠词、物主代词或介词如果与前文重复时，可以省略，如：I like red wine better than white (wine).The lightning flashed and (the) thunder crashed.Please take good care of these flowers and (these) plants.We lived in Beijing and (in) Shanghai for some time.2）重复出现的形容词，省略后边的；两个或两个以上被形容词修饰的同一名词，前边的则常被省略。

状语从句的省略
状语从句的省略状语从句的省略是指使语言的精炼将状语从句进行简化。
需满足两个条件: 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。
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：The higher the temperature (is), the greater the pressure (is ).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。
