高考英语：英语从句与倒装句及写作句型升级
高考英语：英语从句与倒装句及写作句型升级英语从句与倒装句及写作句型升级，以下是店铺为大家编辑的英语学习方法文章，仅供考生参考，欢迎大家阅读!英语写作：如何让句型升级利器一：定语从句要想写出定语从句，首先要保证两个简单句有重复词汇，再将含有重复词汇的两个简单句合成定语从句。
1. 合并法【使用条件】写作要点中有重复词汇【例1】假设你是育才中学学生会主席李华。
你校将举办一次英语演讲比赛(speech contest)，希望附近某大学的外籍教师Smith女士来做评委。
请参照以下比赛通知给她写一封信。
英语演讲比赛主题：人与自然时间：6月15日下午2：00～5：00地点：501教室参赛选手：10名学生联系人：李华(电话：44876655)欢迎大家光临【分析】首先阅读题干，题干中没有直接出现重复词汇，但是稍加分析不难发现，在描述主题时，肯定会多次出现演讲比赛。
比如：我校将举办一场演讲比赛，演讲比赛的主题是人与自然，演讲比赛在什么时间什么地点举行。
除此之外，主题：人与自然这个要点与参赛选手：10名学生也可以说成演讲比赛的主题是人与自然，10名学生将讨论这个主题。
只要确定写作要点中可以出现两个含有重复词汇的句子，我们就能通过三个步骤写出定语从句。
【步骤】第一步：把两个句子翻译成英语简单句，并标出重复词汇。
以我们刚刚分析过的要点为例：① The topic of this contest is Man and Nature.②Ten students will talk about Man and Nature.第二步：确定主句和从句，将从句的重复词汇用对应关系词替换并提至从句句首。
在确定主句和从句时，考生只需要根据中文构思判断合成后的句子主要想表达哪个要点，含有该要点的句子就是主句。
在用对应关系词替换时，考生看到重复词汇指物时用关系代词which / that来替换，指人时用关系代词who / that来替换，指时间时用关系副词when来替换。

当堂检测：
下面是对本节课内容的当堂检测，请同学们认真完成，以检验自己对定语从句的理解和掌握程度。
（2）组织学生参加英语角活动，与其他同学一起讨论定语从句的用法和实际应用，以提高学生的口语表达能力和团队协作能力。
（3）鼓励学生利用课后时间，参加英语写作比赛或口语比赛，将定语从句的知识运用到实际比赛中，以提高学生的综合素质和能力。
（4）建议学生定期参加英语角活动或与其他同学进行英语对话，以提高学生的实际应用能力和口语表达能力。
首先，我发现学生在理解定语从句的关系词时存在一定的困难。由于关系词的选择和使用是定语从句的重点和难点，我在课堂上花了较多的时间进行讲解和举例。通过对比和练习，学生们逐渐掌握了关系词的用法，但仍有部分学生表现出迷茫。针对这一问题，我计划在今后的教学中增加更多的练习题，让学生在实际操作中加深对关系词的理解和运用。

掌握高中定语从句用法七招详解
掌握高中定语从句用法七招详解定语从句在整个高中英语学习阶段占据主要位置，是高中英语学习的重点，同时也是大多数高中生所望而生畏的难点。
那么究竟定语从句的学习怎样才更高效呢？什么样的定语从句的学习方法能为广大高中生说掌握呢？以下是笔者对定语从句进行的归纳和总结。
一、定语从句中的关系词（关系代词、关系副词）关系代词：that(指代人、物；充当主语和宾语)；which（指代物，充当主语和宾语）；who（指代人，充当主语和宾语）；、whom（指代人，充当宾语）；whose（指代人、物，充当定语，在定语从句中和名词一起充当主语或宾语）；as（指代人、物，充当主语、宾语、表语）关系副词：where（充当地点状语）；When（充当时间状语）；Why (充当原因状语)；二、定语从句的使用用法首先：我们要明白关于定语从句两个最基本的概念：是个完整的句子，而且在句中充当定语成分。
去掉定语从句后，剩下的仍然是个完整的句子，不过加上定语从句后，更方便我们对句子本身意思的理解。
例：The visitor (whose passport was stolen) was on his way to the US.护照被偷的那位乘客正在去美国的路上。
解析：括号里面的为定语从句，去掉后剩下的部分仍然是完整的，不缺少任何成分。
其次：找出定语从句中的先行词，判断出指代人或者物之后，选择相应的关系代词，代入定语从句，因为定语从句也必须是个完整的句子，所以我们这个时候就要判断所选择的关系代词在定语从句中充当什么成分。
比如上面的例子：Whose passport was stolen. 中whose指代the visitor’s，代入定语从句后完整的句子就是：The visitor’s passport was stolen.（那位游客的护照被偷了。
）是个完整的句子。
The visitor’s passport在句中充当主语成分。
初学定语从句的高一同学们在课堂时老师经常会让我们讲两个简单句合并成一个含有定语从句的复杂句，以下我们介绍一下合并的方法。
高中英语定语从句解题技巧(含例题)
定语从句解题技巧（含例题）英语中两个意义相关的分句不能不用连词而直接放在一起，也不能只用逗号来连接，可以说英语并列句和复合句构成的基本规律是：英语的两个分句之间有且只有一个连词。
这条规律为我们学习和运用这类句型提供了重要的依据。
定语从句是英语复合句的一种，它是指用一个句子去修饰限制另一个句子中的某个名词、代词，两个句子之间通过关系代词（that, which, who, whom, whose, as.）或关系副词（when, where, how）连接起来，关系代词有时可以省略；在特定情况下，关系代词（which, as）也可指代主句整句话或一部分句子成分所表达的内容。
当我们解题时遇到复合句的考查题目时，我们便可以根据定语从句的上述含义判断该题是不是定语从句，如果是，我们可先将不是关系代词或关系副词的选项去掉，然后采用“代入原则”并同时结合定语从句的关系词之间的相关区别来进行解题。
所谓“代入原则”就是试着把先行词即被定语从句修饰限制的那个词放进从句中，能直接代入的就用关系代词（不包括whose），不能直接代入的可能有三种情况，要么用关系副词，要么用介词加关系代词which 或whom，要么就用关系代词whose。
下面就用例句来具体说明这种解题技巧。
一．直接代入的情况：1． Women____ drink more than two cups of coffee a day have a greater chance of having heart disease than those____ don’t.A. who; /B. /; whoC. who; whoD. /; /该题中的先行词women和those都可直接代入各自的从句中，都在从句中做主语，根据关系代词的使用规律，我们应该用who或that，而且不能省略，所以答案是C。
2． Do you still remember the chicken farm___ we visited three months ago?A. whereB. whenC. thatD. what该题的先行词the chicken farm就是visited的宾语，只能用关系代词that, which或省略关系代词，所以答案是C。
英语写作中的句子合并技巧
英语写作中的句子合并技巧在英语写作中，句子的合并是一项重要的技巧。
通过合并句子可以使文章更具连贯性和流畅性，提升文章的表达能力。
本文将介绍几种常用的句子合并技巧，并提供一些实用的例子来帮助读者更好地理解和运用。
1. 使用连接词使用适当的连接词可以将两个或多个简单句合并成一个复合句，使句子之间的关系更加明确。
常用的连接词包括：and（和）、but（但是）、or（或者）、so（所以）、however（然而）等。
下面是一些例子：- 原句：He went to the store. He bought some groceries.合并后：He went to the store and bought some groceries.- 原句：She was tired. She couldn't finish her homework.合并后：She was tired, so she couldn't finish her homework.2. 使用分词短语分词短语可以用来合并两个相关的动作或事件，可以增强句子之间的逻辑关系。
常见的分词形式有过去分词和现在分词。
以下是一些例子：- 原句：The car crashed into a tree. The driver was texting on his phone.合并后：Texting on his phone, the driver crashed the car into a tree.- 原句：The children finished their homework. They went out to play.合并后：Having finished their homework, the children went out to play.3. 使用定语从句定语从句是一个由关系代词或关系副词引导的从句，用来修饰先行词。
通过使用定语从句，可以将两个句子合并成一个，为句子增添细节和信息。
定语从句合并句子
定语从句合并句子定语从句是指修饰名词或代词的从句，用来说明或限定名词或代词的内容。
定语从句通常由关系代词或关系副词引导，如，who, whom, whose, which, that, when, where等。
在英语中，我们经常会遇到多个定语从句并列的情况，这时就需要对定语从句进行合并，以简化句子结构，使语言更加简洁明了。
定语从句合并句子的目的是为了避免重复和冗长，提高语言表达的效率和流畅度。
合并定语从句可以让句子更加紧凑，更具逻辑性，让读者更容易理解句子的意思。
下面我们来看一些定语从句合并句子的具体方法和技巧。
首先，我们需要注意的是，定语从句合并句子的前提是定语从句之间存在共同的先行词，即被修饰的名词或代词相同。
这样才能将定语从句合并为一个句子，而不改变句子的原本意思。
其次，当两个定语从句都是由关系代词引导时，我们可以将它们合并为一个定语从句。
例如：The book that I bought yesterday is very interesting.The book which I read last week is also very good.合并后的句子为：The book that I bought yesterday and which I read last week is very interesting.另外，当两个定语从句都是由关系副词引导时，我们也可以将它们合并为一个定语从句。
例如：This is the place where I first met her.This is the time when I realized my mistake.合并后的句子为：This is the place where and when I first met her.需要注意的是，在合并定语从句时，我们需要保持句子的逻辑关系和语法结构的完整性。
合并后的句子应该依然清晰明了，不会造成歧义或混淆。
高中英语语法突破——定语从句
③As is often the case...“……是常有的事”
As is often the case, people tend to talk loud in public places, annoying others around.
一、定语从句的类型 1．关系代词引导的定语从句 关系代词 who, whom, whose, that, which 引导的定语是写作的一大 重点。
①Secondly, you will make some good friends who are also
interested in playing table tennis. 第二，你会交到一些好朋友，他们也很喜欢打乒乓球。 ②Our school, which is located in the northwest of Jinan, has a吸引眼球 Nhomakorabea定语从句
定语从句的正确使用能够比较明显地反映出考生对于语言具有较高的掌 握能力，所以建议考生一定要在写作中至少使用一个恰到好处的定语从句。
1．用 as, which 引导非限制性定语从句写句子 which 和 as 引导的非限制性定语从句在高考范文中更是屡见不鲜。 which 引导非限制性定语从句，意为“这……” ①Last week, we took the foreign students to experience the authentic tea culture, which turned out to be extremely rewarding. 上周，我们带领外国学生体验了正宗的茶文化，结果证明非常值得。 ②Our teachers encourage us to take part in some social practice in our summer holidays, which they think can help us get fully developed. 老师鼓励我们暑假积极参加社会实践， 他们认为这有助于我们全面发 展。
用合并句子法讲解高中定语从句
用合并句子法讲解高中定语从句作者：罗茜来源：《校园英语·上旬》2016年第10期【摘要】定语从句是英语句子中构成长难句不可或缺的句型之一，对它的掌握一直是中国学生语法学习中的难点，很多学生无法独立理解和分析，更不用说在作文中的正确使用。
本文旨在用合并两个简单句的方法引入定语从句的演变并讲解定语从句中的关系代词，从而让高中生在定语从句的学习中登堂入室。
【关键词】合并句子定语从句关系代词学习背景及基础知识的准备语法是语言的重要组成部分，必然是教师教学过程中的核心内容之一。
在高中语法教学中，定语从句就是教师讲解的重点，却又是许多学生的语法学习中的短板。
虽然学生们在初中阶段已经学过定语从句，多数能读懂含有简单定语从句的句子，但高中阶段对定语从句运用的能力要求更高，不仅要求学生理解其句法功能，还要求学生能运用定语从句进行书面表达。
要求提高了，难度也随之增加。
英语和汉语中都有定语，英语中的定语从句是汉语中所没有的；而且中英两种语言的句型结构也有着巨大差异。
这就对中国学生理解定语从句造成了一定的障碍。
所以，课前学生必须清晰理解以下知识：1.主语和谓语是英语句子不可或缺的两个部分，除少数句子（如祈使句和感叹句等）外，一句话必须同时具备主语和谓语，所表达的意思才完整；在复合句中，主句和从句各自具有属于自己的独立的主语和谓语。
2.定语的概念：描述见表1。
3.英语中有5种简单句的基本句型，它们是构成一切长难句的基础。
观察例句，引出定语从句的相关概念如果直接把概念化的东西平铺直叙给学生念一遍，语言学习会枯燥而无味，而且很突兀。
这时，例句的展现，引导式的分析就很重要了，如：The students （who do not study hard） will not pass the exam.让学生观察例句，此时在教师的指导下找出主句的主干：The students will not pass the exam，即主谓宾结构。

（4） which\that==the pen, 在定语从句中做宾语的成分，并连接先行词和定语从句。
做宾语的关系词which\that 可以省略This is the pen (he bought yesterday).
先行词为物时
（1）This is the pen. He bought the pen yesterday.
（2）This is the pen (he bought the pen yesterday).
（3）用关系词替换从句中重复的the pen, 关系词中能作宾语并代表物的是which, that
3. 关系词在定语从句中充当定语
(1) I helped the man. The man’s car was broken.
(2) I helped the man (the man’s car was broken).
(3) the man’s 是名词所有格，起到定语的作用修饰 car, 用关系词替换从句中重复的the man, 关系词中能作定语，表示“谁的”是whose
(4) who\that==the boys, 在定语从句中做主语的成分，并连接先行词和定语从句。
先行词为物时
（1）I found the letter. The letter came yesterday.
（2）I found The letter( the letter came yesterday).
(4) when=on the day, 在定语从句中做时间状语，并连接先行词和定语从句。
地点状语
(1) The house has been pulled down. I lived in the house ten years ago.
I once lived in a house (of which the roof has fallen in). 4. 关系词在定语句中充当状语时 时间状语
(1) I still remember the day. I first came to the school on the day.
I once lived in a house (the roof of the house has fallen in).
I once lived in a house (whose roof has fallen in).
此句还可以改为：
I once lived in a house (the roof of which has fallen in).
（3）用关系词替换从句中重复的the letter, 关系词中能作主语并代表物的是which, that
I found The letter(which\that came yesterday).
（4）which\that==the letter, 在定语从句中做主语的成分，并连接先行词和定语从句。
I helped the man (whose car was broken).
(4) whose=the man’s, 在定语从句中做定语，并连接先行词和定语从句。
Whose不但可以表示“谁的”，还可以指物，表示“什么的”。例如：
I once lived in a house. The roof of the house has fallen in.
2. 关系词在定语从句中充当宾语
先行词为人时
（1）The man is my friend. You met the man just now
（2）The man (you met the man just now) is my friend.
（3）用关系词替换从句中重复的the man, 关系词中能作宾语并代表人的是whom, that
1、关系词在定语从句中充当主语
先行词为人时
（1）两个单句为The boys are from Class One. The boys are playing football.
（2）第一句为主句，第二句为从句，将两个单句合并为一句。
The boys（the boys are playing football） are from Class One.
(2) I still remember the day (I first came to the school on the day).
(3)重复的词是the day, on the day在从句中充当时间状语的成分，关系词中能作时间状语的词是when.
I still remember the day (when I first came to the school).
利用句子合并来学习定语从句
定语从句
两个术语：先行词，关系词
先行词：被修饰的名词、名词词组或代词
关系词（关系代词或关系副词）：连接先行词与定语从句的词。
关系代词有：who, whom, whose, that, which等；关系副词有：when, where, why等；
(3) 括号中句子里的主语the boys, 和先行词是同一个词，应该用关系词替换从句中重复的the boys. The boys 在从句中作主语，关系词中能作主语并代表人的是who, that
The boys（who\that are playing football） are from Class One.
The man (whom\that you met just now) is my friend.
（4）whom\that==the man, 在定语从句中做宾语的成分，并连接先行词和定语从句。
做宾语的关系词whom\that 可以省略The man ( you met just now) is my friend.
