定语:

什么是定语

修饰成分和被修饰成分之间大多数情况下没有逗号分隔,可以前置修饰,也可以后置与被修饰成分,大多数情况下修饰句子之中的某一个成分(名词),尤其是主语和宾语。

1.形容词:

前置定语:单个形容词

The handsome boy

后置修饰:形容词短语

The country different from China is America.

China is a country different from America.

China is a country different from America.

China is a country different from America.

2.非谓语:

前置:单个分词

Developed country

Developing country

Swimming pool

非谓语后置:分词短语

The water to drink

The man attacked by the dog

The boy playing basketball

3.定语从句:只能后置

The man who is playing football is eating an apple.

状语修饰:修饰动词(修饰句子中的某一个成分,也可以修饰整个句子)

修饰成分和被修饰成分之间大多数情况下有逗号分隔,可以前置修饰,也可以后置,也可以放在中间,大多数情况下修饰整个句子

1.副词(修饰主句子里的某一个成分:动词)

He is laughing happily.

2.非谓语:有逗号分隔,不修饰主句之中的某一个成分

Playing football, he is eating an apple. (表示伴随)

Attacked by the dog, the man cries. (表示原因)

He, playing football,is eating an apple.

He is eating an apple, playing football.

3.状语从句可以有逗号分隔,也可以没有逗号分隔,不修饰主句之中的某一个成分

The man cried because he was attacked by the dog.

Because he was attacked by the dog, the man cried

特别再谈一次非谓语作状语

同是一个主干成分“The man cried.”让“attacked by the dog”来修饰,即可以作为定语来修饰,也可以作为状语来修饰。

1.“attacked by the dog”作状语修饰,翻译成:“被狗咬了,那个人哭了。”

Attacked by the dog, the man cries. (表示原因)

The man, attacked by the dog, cried.

The man cried, attacked by the dog.

2.“attacked by the dog”作为定语来修饰,翻译为“那个被狗咬的人哭了”

The man attacked by the dog cried.

when 和 where 引导定语从句的用法

when 和 where 引导定语从句的用法 定语从句既是英语语法的一个重点,同时又是一个难点。说它是难点,主要难在两点上:一点是如何正确判断什么样的汉语句子要译为英语的带定语从句的复合句;另一点是定语从句的引导词较多(包括关系代词who, that, which, as 和关系副词when, where, why),而且其用法也较复杂。那么到底什么情况下用when和where来引导定语从句呢?它们又该怎么用呢?下面就举例说明: 一、when:当主句中的先行词(即主句中被后面定语从句修饰的词)是表示时间意义的名词时,它只能作定语从句的时间状语,放在定语从句句首。如果定语从句的引导词是作该定语从句的主语或宾语,则要改用关系代词that或which来引导。例如: The days when we used foreign oil are gone. 我们用洋油的日子一去不复返了。 I'll never forget the day when I was born. (=I'll never forget my birthday.) 我永远不会忘记我出生的日子。 It happened in November when the weather was wet and cold. 这事发生在天气又湿又冷的十一月。 In the years that (which) followed, Marx kept on studying English and using it. 在这之后的几年中,马克思继续学习和使用英语。(that作定语从句"that followed"的主语) The day (that) I always remember in all my life is my birthday. 我一生中最难忘的日子是我的生日。(that作定语从句"that I always remember in all my life"的宾语,that可以省略)

地点状语与定语从句的区别

where引导的定语从句和地点状语从句的区别是什么? 最简单的办法是看where是否有指代先行词 应到定语从句还是状语从句的区别主要可以从以下三点来看: 一、where引导定语从句时, where是关系副词, 在从句中作地点状语, 其前面有表示地点的先行词, where引导的从句修饰先行词。例如: The bookshop where I bought this book is not far from here. This is the house where I lived two years ago. We will start at the point where we left off. 二、where引导状语从句时, where是从属连词, where引导的从句修饰主句的谓语动词, where前面没有表示地点的先行词。例如: Wuhan lies where the Changjiang River and the Han Jiang River meet. Make a mark where you have any doubts or questions. I found my books where I had left them. 有时, where引导的地点状语从句兼有抽象条件含义, 可放在主句的前面, 而where引导的定语从句则不能。例如: Where there is a will, there is a way. 〔谚语〕有志者事竟成。 Where there is water, there is life. 有水的地方就有生命。 三、在有些情况下, where引导的定语从句可转换为where引导的地点状语从句。例如: A tall building was put up at the place where there used to be a desert. (=A tall building was put up where there used to be a desert. )在以前曾是沙漠的地方盖起了一幢高楼。 Bam boo grows best in places where it is warm and where it rains often. (=Bamboo grows best where it is warm and where it rains often. )温暖而多雨的地方最适合于竹子生长。

When引导的定语从句与时间状语从句的区分

一、从句是如何出题的? 1. 时态 2. 考连接词 3. 考语言顺序 二、学好从句的两个基本条件 1. 时态 2. 从句的三个必须:①必须是句子;②必须有连接词;③必须是陈述句 三、状语从句、宾语从句、定语从句重点 1.如何判断何种从句 2. 从句的时态 3. 从句的连接词与扩展 4. 经典单选、从句与选词、长句子分析 四、如何判断三种从句 1. 状语从句无先行词 2. 宾语(表语)从句无先行词有动词或词组 3. 定语从句先行词多为名词或代词 一、When引导的定语从句与时间状语从句的区分 1. when的译法不同。在时间状语中,when 翻译成“当……的时候” I want to be a teacher when I grow up. 当我长大的时候,我要做一名老师。在定语从句中,when不翻译。I won't forget the day when he says he loves me. 我不会忘记他说爱我的那一天。 2. 在时间状语中,when从句前面或后面是句子;定语从句中,when 从句不能位于句首,且通常when前为表示时间的名词day、year等。 3. when在从句的作用不同。在时间状语从句中,when是连词,只起连接主句和从句的作用,不做从句的任何成分。不过when引导的时间状语从句修饰主句的谓语,做主句的时间状语。 在定语从句中,when是关系副词,在从句中代替先行词做从句的时间状语,修饰从句的谓语。 例1 I will always remember the days when I lived with my

grandparents in the country. 例2 I always remember the days in the country when I see the photo of my grandparents. 点评:例1意为“我会永远记得跟我祖父母一起住在乡下的那些日子”,其中when 引导的是一个定语从句, 修饰the days, when在从句中作时间状语。例2意为“当我看到祖父母的照片时,总是会想起在乡下的那些日子”,其中when 引导的从句并不修饰前面的名词the country,因此可判定为时间状语从句。 例1中的when可用in which替代,即从句可改为...in which I lived with my grandparents in the country. 例2中从句前有名词,但根据句意可 知并不是从句所修饰的对象,也不能用“介词+ which”来替代。 二、判断关系代词与关系副词 方法一:用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要求用关系副词。例如: This is the mountain village where I stayed last year. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you. 我永远不会忘记与你共事的日子。 判断改错: 1. This is the mountain village where I visited last year. 2. I will never forget the days when I spent in the countryside. 3. This is the mountain village (which)I visited last year.

宾语、定语、状语从句区别

1.定语从句,也就是做定语(修饰名词的句子成分叫做定语)的从句 定语从句实际上起到了形容词的作用,所以也叫形容词性从句。 和定语一样,定语从句是修饰名词的成分。 如:the girl who she talk about .这个女孩就是她谈论的那个。 很明显who she talk about 是在修饰这个the girl 的 2.宾语从句,它在句子中作宾语(动作的承受者)成分,一般主句缺宾语时用它。 如:she are talking about where the boy comes from . 她在谈论这个男孩来自哪里。 很明显where...from在句子中做了宾语的成分。 3.状语从句,与状语一样,修饰谓语、非谓语动词、定语、状语或整个句子的成分。如:I will call you as soon as I arrive in Beijing. 我到北京就将给你打电话。 很明显这是由as soon as引导的时间状语从句。 1.定语从句,也就是做定语(修饰名词的句子成分叫做定语)的从句 定语从句实际上起到了形容词的作用,所以也叫形容词性从句。 和定语一样,定语从句是修饰名词的成分。 如:the girl who she talk about .这个女孩就是她谈论的那个。 很明显who she talk about 是在修饰这个the girl 的 2.宾语从句,它在句子中作宾语(动作的承受者)成分,一般主句缺宾语时用它。 如:she are talking about where the boy comes from . 她在谈论这个男孩来自哪里。 很明显where...from在句子中做了宾语的成分。 3.状语从句,与状语一样,修饰谓语、非谓语动词、定语、状语或整个句子的成分。如:I will call you as soon as I arrive in Beijing. 我到北京就将给你打电话。 很明显这是由as soon as引导的时间状语从句。 1.定语从句,也就是做定语(修饰名词的句子成分叫做定语)的从句 定语从句实际上起到了形容词的作用,所以也叫形容词性从句。 和定语一样,定语从句是修饰名词的成分。 如:the girl who she talk about .这个女孩就是她谈论的那个。 很明显who she talk about 是在修饰这个the girl 的 2.宾语从句,它在句子中作宾语(动作的承受者)成分,一般主句缺宾语时用它。 如:she are talking about where the boy comes from . 她在谈论这个男孩来自哪里。 很明显where...from在句子中做了宾语的成分。 3.状语从句,与状语一样,修饰谓语、非谓语动词、定语、状语或整个句子的成分。如:I will call you as soon as I arrive in Beijing. 我到北京就将给你打电话。 很明显这是由as soon as引导的时间状语从句。 1.定语从句,也就是做定语(修饰名词的句子成分叫做定语)的从句 定语从句实际上起到了形容词的作用,所以也叫形容词性从句。 和定语一样,定语从句是修饰名词的成分。 如:the girl who she talk about .这个女孩就是她谈论的那个。 很明显who she talk about 是在修饰这个the girl 的 2.宾语从句,它在句子中作宾语(动作的承受者)成分,一般主句缺宾语时用它。 如:she are talking about where the boy comes from . 她在谈论这个男孩来自哪里。 很明显where...from在句子中做了宾语的成分。

定语从句与强调句和状语从句的区别

定语从句与其易混淆句型的辨析 众所周知,定语从句是高中英语学习中的一个语法重点,老师、同学们都对此予以重点关注。由此造成了这样一种现象:做题时,一遇到从句就往定语从句上想,尤其容易把一些形式上与定语从句相似的句型(主要是同位语从句、强调句、地点和时间状语从句)也当作定语从句来理解,结果产生错误。因此,从某个方面来说,解答定语从句题的关键是弄清它和易混淆句型之间的区别。 一、定语从句与同位语从句 定语从句和同位语从句都置于被修饰的名词或代词之后,形式上非常相似,尤其是由that引导时,最难区分。实际上,两者的根本区别在于句法功能不同,与先行词的关系不同。 1. 句法功能不同 定语从句相当于一个形容词,用来修饰、描述或限制其前面的名词、代词(称为先行词)或整个句子;同位语从句则相当于一个名词,是先行词所述内容的展开,即说明先行词的具体内容。 定语从句的引导词that在从句中一定充当句子成分;而同位语从句中的引导词that(被称为连接代词)在从句中只起连接作用,不充当任何句子成分。 定语从句的引导词在从句中作宾语或状语时,可以省略或被其他词代替;而同位语从句的引导词则一般不能省略,也不能被代替。 例1The news (that / which)we picked up from his informal conversation is true.我们从他的闲谈中听到的那个消息是真实的。 例2The news that Mr Li will teach us English next semester is true. 李先生下学期将教我们英语这个消息是真实的。 点评:例1的中that从句是定语从句,其作用相当于一个形容词,用来限定the news,that在从句中作宾语,可省略。例2中的that从句是同位语从句,其作用相当于一个名词,本身就是the news的内容,that不能省略。 2. 与先行词关系不同 定语从句所修饰、限定的先行词可以是名词或代词,当that省略时,定语从句本身是一个不完整的句子。而同位语从句通常与一些本身有具体内容可展开的名词连用,对这些名词进行补充说明或解释。常见的此类名词有:answer,belief,doubt,decision,explanation,fact,hope,idea,information,message,news,order,possibility,problem,promise,question,reason,story,suggestion,thought,truth等。同位语从句本身是一个完整的句子,常用that连接而不是用which 引导,that本身不充当句子成分,表示疑问意义的名词(如doubt,question等)后也可用whether,who,what等疑问词引导。 例3The fact (that / which) she told me yesterday is very important.她昨天告诉我的事实非常重要。 例4The fact that she hasn’t known the result of the examination is clear.她还不知道考试成绩这个事实是显而易见的。

过去进行时、when和while引导时 间状语从句的区别

过去进行时过去进行时表示过去某一时刻或者某段时间正在进行或发生的动作,常和表过去的时间状语连用,如: 1. I was doing my homework at this time yesterday. 昨天的这个时候我正在做作业。 2. They were waiting for you yesterday. 他们昨天一直在等你。 3. He was cooking in the kitchen at 12 o'clock yesterday. 昨天12点,他正在厨房烧饭。 过去进行时的构成: 肯定形式:主语+was/were+V-ing 否定形式:主语+was not (wasn't)/were not (weren't)+V-ing 疑问形式:Was/Were+主语+V-ing。 基本用法: 1. 过去进行时表示过去某一段时间或某一时刻正在进行的动作。常与之连用的时间状语有,at that time/moment, (at) this time yesterday (last night/Sunday/week…), at+点钟+yesterday (last night / Sunday…),when sb. did sth.等时间状语从句,如: 1)What were you doing at 7p.m. yesterday? 昨天晚上七点你在干什么? 2)I first met Mary three years ago. She was working at a radio shop at the time. 我第一次遇到玛丽是在三年前,当时她在一家无线电商店工作。 3)I was cooking when she knocked at the door. 她敲门时我正在做饭。 2. when后通常用表示暂短性动词,while后通常用表示持续性动词,而while所引导的状语从句中,谓语动词常用进行时态,如: When the car exploded I was walking past it. = While I was walking past the car it exploded. 3. when用作并列连词时,主句常用进行时态,从句则用一般过去时,表示主句动作发生的过程中,另一个意想不到的动作发生了。如: I was walking in the street when someone called me. 我正在街上走时突然有人喊我。 4. when作并列连词,表示“(这时)突然”之意时,第一个并列分句用过去进行时,when引导的并列分句用一般过去时。如:

多项定语和多重状语的排序

1多项定语的一般语序是:①领属性定语,时间、处所定语;②表指称数量的短语; ③动词或动词性短语;④形容词或形容词性短搜索语;⑤名词或名词性短语。另外应当注意,带“的”的定语应放在不带“的”的定语之前。如:花园里(领属性的)那(指示代词)几朵(数量词)盛开的(动词)美丽的(形容词)红色(形容词)玫瑰花(名词)被人摘走了。如果违反多项定语语序的一般规律,就会造成定语语充不当的错误。病例1 1956年,北京故宫博物院展出了2900前新出土的文物。(句中表领属性的定语“新出土”应放在表时间短语“2900年前”的前面)。病例2 大厅里陈列着各式各样的、不同时期的任长霞同志生前用的衣物、书籍与批阅过的文件,赌物思人,悲从中来,大家早已热泪盈眶。(“衣物、书籍与批阅过的文件”之前的多重定语语序失当。领属性定语“任长霞同志生前用的”,应放在最前面,接着是时间定语“不同时期的”,最后是“各式各样的”,否则“各式各样”、“不同时期”有修饰“任长霞”之嫌,容

易造成歧义。) 2、多项状语语序不当多项状语的一般语序是:①表目的、原因或条件的介宾短语;②表时间、处所的词或短语;③表范围程度的短语;④表情感的词或短语。另外,表对象的介宾短语一般紧挨在中心语前。即:为了什么(目的)→何时(表时间的名词)→何地(表处所的介宾短语)→范围(表范围程度的副词)→怎样(表情态的形容词)→同谁(表对象的介宾短语)。如:许多教师今天早上(时间)在会议室里(表处所)都(表范围)热情地(表情态)同他(表对象)交谈。如果违反多项状语语序的一般规律,就会造成状语语序不当的错误。病例3 居里夫人艰辛地在简陋的工作室里经过漫

When和While的区别(可编辑修改word版)

1、When 和While 的区别 when,while 都有“当……时候”的意思. when 既可表示某一点时间,也可以表示某一段时间. (一)在when 引导的时间状语从句中,其谓语动词可以是延续性的,也可以是非延续性的,可与主句中的谓语动词同时发生,也可在其后发生. 例如: 1、I was just reading a book when she came into my room. 她走进我房间时,我正在看书. (二)、while 只能表示某一段时间,不能表示某一点时间.在while 引导的时间状语从句中,其谓语动词只能是延续性的,而且也只能与主句中的谓语动词同时发生或存在. 例如: 1、While Jim was mending his bike, Lin Tao came to see him. 正当吉姆修自行车时,林涛来看他. Remark: 由when 引导的时间状语从句,主句用过去进行时,从句应用一般过去时;如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while 引导,如: a. When the teacher came in, we were talking. 2、倒装知识点 完全倒装 表示地点的副词here, there 置于句首, 且主语是名词(不是代词) 时 表示时间、方向的副词或介词短语置于句首, 且主语是名词(不是代词) 时 作表语的形容词、分词、介词短语、such 置于句首时 部分倒装 “ only+状语” 置于句首, 主句需要部分倒装 具有否定意义或半否定意义的副词以及含否定词的介词短语置于句首作状语时“so 或neither + 助动词/情态动词/be 动词+主语”表示“……也/也不” so/such...that...句型 以had/were/should 开头省略if 的虚拟条件句

如何区分状语从句和定语从句

如何区分状语从句和定语从句 以下句子中的when a bomb exploded near the Stock Exchange作何种成分?纵观国内出版的语法书,一般都认为是时间状语从句,它跟last night一样,都是时间状语。但感觉又不像,请问您怎么看? Ten people were killed and several were injured last night when a bomb exploded near the Stock Exchange. 昨天晚上一颗炸弹在股票交易所附近爆炸,造成十人死亡,数人受伤。 【问题】when a bomb exploded near the Stock Exchange. 到底是时间状语从句,还是定语从句? 【答】以下是我的详细分析,并给出理由。 last night与when a bomb exploded near the Stock Exchange 到底存在着什么关系? 它们之间可能存在的3种关系: 1. 并列关系(如果是并列关系,那么when 就是状语从句,跟last night 共同修饰谓语动词) 2. 同位关系(如果是同位关系,那么when 就是名词性从句,不是状语从句) 3. 修饰关系(如果是修饰关系,那么when 就是定语从句,修饰限定last night) 下面我从这3种关系入手,进行深度分析,最后判断它们是不是先行词和定语从句的关系。 1. 并列关系? 如果是并列关系,那么,last night 和when 之间应该有或者可以加上and, or 等连词连接,以“A and B”或“A or B” 的结构出现,例如: He stayed at home yesterday and today. 他昨天和今天都呆在家里。 It won't make much difference whether you go today or tomorrow. 你今天或明天去没有多大关系。

过去进行时、when和while引导时间状语从句的区别

过去进行时 过去进行时表示过去某一时刻或者某段时间正在进行或发生的动作,常和表过去的时间状语连用,如: 1. I was doing my homework at this time yesterday. 昨天的这个时候我正在做作业。 2. They were waiting for you yesterday. 他们昨天一直在等你。 3. He was cooking in the kitchen at 12 o'clock yesterday. 昨天12点,他正在厨房烧饭。 过去进行时的构成: 肯定形式:主语+was/were+V-ing 否定形式:主语+was not (wasn't)/were not (weren't)+V-ing 疑问形式:Was/Were+主语+V-ing。 基本用法: 1. 过去进行时表示过去某一段时间或某一时刻正在进行的动作。常与之连用的时间状语有,at that time/moment, (at) this time yesterday (last night/Sunday/week…), at+点钟+yesterday (last night / Sunday…),when sb. did sth.等时间状语从句,如: 1)What were you doing at 7p.m. yesterday? 昨天晚上七点你在干什么? 2)I first met Mary three years ago. She was working at a radio shop at the time. 我第一次遇到玛丽是在三年前,当时她在一家无线电商店工作。 3)I was cooking when she knocked at the door. 她敲门时我正在做饭。 2. when后通常用表示暂短性动词,while后通常用表示持续性动词,而while所引导的状语从句中,谓语动词常用进行时态,如: When the car exploded I was walking past it. = While I was walking past the car it exploded. 3. when用作并列连词时,主句常用进行时态,从句则用一般过去时,表示主句动作发生的过程中,另一个意想不到的动作发生了。如: I was walking in the street when someone called me. 我正在街上走时突然有人喊我。 4. when作并列连词,表示“(这时)突然”之意时,第一个并列分句用过去进行时,when引导的并列分句用一般过去时。如: 1)I was taking a walk when I met him. 我正在散步,突然遇见了他。 2)We were playing outside when it began to rain. 我们正在外边玩,这时下起雨来了。 过去进行时和一般过去时的用法比较: 1)过去进行时表示过去正在进行的动作,而一般过去时则表示一个完整的动作。 例如:They were writing letters to their friends last night. 昨晚他们在写信给他们的朋友。(没有说明信是否写完) They wrote letters to their friends last night.

地点状语与定语从句的区别教案资料

精品文档 where引导的定语从句和地点状语从句的区别是什么? 最简单的办法是看where是否有指代先行词 应到定语从句还是状语从句的区别主要可以从以下三点来看: 一、where引导定语从句时, where是关系副词, 在从句中作地点状语, 其前面有表示地点的先行词, where引导的从句修饰先行词。例如: The bookshop where I bought this book is not far from here. This is the house where I lived two years ago. We will start at the point where we left off. 二、where引导状语从句时, where是从属连词, where引导的从句修饰主句的谓语动词, where前面没有表示地点的先行词。例如: Wuhan lies where the Changjiang River and the Han Jiang River meet. Make a mark where you have any doubts or questions. I found my books where I had left them. 有时, where引导的地点状语从句兼有抽象条件含义, 可放在主句的前面, 而where引导的定语从句则不能。例如: Where there is a will, there is a way. 〔谚语〕有志者事竟成。 Where there is water, there is life. 有水的地方就有生命。 三、在有些情况下, where引导的定语从句可转换为where引导的地点状语从句。例如: A tall building was put up at the place where there used to be a desert. (=A tall building was put up where there used to be a desert. )在以前曾是沙漠的地方盖起了一幢高楼。 Bam boo grows best in places where it is warm and where it rains often. (=Bamboo grows best where it is warm and where it rains often. )温暖而多雨的地方最适合于竹子生长。 精品文档

when-的用法
