帮忙从下面一段中找出一个语言点或语法,要做一个PPT大学课堂上用,谢谢
我找到两个比较有意义的语法点..也不知道你要用的班上英语水平如何,我就简单说一下不是很深奥的语法了噢。您可以参考一下,如果觉得太浅可以追问,我可以补充噢(*^__^*) 第一个是 Yet with a spoken language we can communicate our entire culture to anyone else who knows that language. 这句话中的(with a spoken language )we can ....此处使用with是一个with短语,即是一般的“介词+名词”,在句中做状语。不构成wih的复合结构。(因为常常会有同学把with+noun和with的复合结构混淆)附:with的复合结构形式一般为:with/without+宾语+复合宾语(也称补足语) 、 补足语由形容词、副词、介词短语、动词不定式或分词充当。分词可以是现在分词,也可以是过去分词(复合结构是分词时,此处的复合结构和宾语构成主谓结构)。此处你也看到了,只有宾语,没有补足语。然后,with的复合结构与一般的with短语的区别: 1,在句子中with结构多数充当状语,表示行为方式,伴随情况、时间、原因或条件,但是With结构在句中也可以作定语. 2,"介词with+名词或代词(组)"组成的一般的with短语在句子中可以作定语和状语。作状语时,它能表示动作的方式、原因,但不能表示时间、伴随和条件。在一般的with短语中,with后面所跟的不是复合结构,也根本没有逻辑上的主谓关系。 第二个语法点:Perhaps the most important thing is 【that the line (dividing us from them) is not as clear as we used to think.】看到了吗,中括号里面是一个表语从句诶、表语从句中的小括号里面是一个动词的ing形式做的定语。语法点就是表语从句,和动词ing作定语。这都是各类语法的两大考点噢,非常重要的。1,表语从句归属于名词性从句,名词性从句分为:主语从句,宾语从句,表语从句以及同位语从句。顾名思义嘛,是什么从句就在主句 句子中 充当什么成分。通常情况下,民间俗气的判断表语从句的方法(也就是没有明文规定的,或许存在某些高深的问题)是:be动词后面的宾语从句=表语从句。名词性从句的意思就是..由连接词引导的从句,在句子中充当名词性成分。2,动词分词作定语,分为v-ing和v-ed作定语。动词分词作定语,可以和定语从句互换。比如:the line dividing us from them...可以唤作:the line which devids us from them...呃,累死了....楼主看看行了吗,求采纳啊!
英语中的定语从语,宾语从句,状语从句的详解
定语从句就是一个从句在整个句子中充当定语的成分宾语从句就是一个从句在整个句子中充当宾语的成分状语从句就是一个从句在整个句子中充当状语的成分定语从句(一)、定义:在复合句中,修饰某一名词或代词的从句叫做定语从句。定语 定语用来限定、修饰名词或代词的,是对名词或代词起修饰、限定作用的词、短语(动词不定式短语、动名词短语和分词短语)或句子,汉语中常用‘……的’表示。主要由形容词担任,此外,名词,代词,数词,分词,副词,不定式以及介词短语也可以来担任,也可以由一个句子来担任。单词作定语时通常放在它所修饰的词之前,作前置定语。短语和从句作定语时则放在所修饰的词之后,作后置定语。 定语从句是指在一个句子中作定语的句子,定语从句要放在所修饰的词后。如:1) The man who lives next to us is a policeman. 2) You must do everything that I do. 上面两句中的man和everything是定语从句所修饰的词,叫先行词,定语从句放在先行词的后面。引导定语从句的词有关系代词that, which, who(宾格who, 所有格whose)和关系副词where, when、why关系词常有三个作用:1、引导定语从句 2、代替先行词 3、在定语从句中担当一个成分(二)、关系代词引导的定语从句1.who指人,在从句中做主语(1)The boys who are playing football are from Class One.(2)Yesterday I helped an old man who lost his way.2. whom指人,在定语从句中充当宾语,常可省略。 (1) Mr. Liu is the person (whom) you talked about. 注意:关系代词whom在口语和非正式语体中常用who代替,可省略。 (3) The man who/whom you met just now is my friend.3. which指物,在定语从句中做主语或者宾语,做宾语时可省略 (1) Football is a game which is liked by most boys. ( which 在句子中做主语) (2) This is the pen (which) he bought yesterday. ( which 在句子中做宾语)4. that指人时,相当于who或者whom;指物时,相当于which。在宾语从句中做主语或者宾语,做宾语时可省略。 (5) The people that/who come to visit the city are all here. (在句子中做主语) (6) Where is the man that/whom I saw this morning? (在句子中做宾语)5. whose通常指人,也可指物,在定语从句中做定语 (1) He has a friend whose father is a doctor. (2) I lived in a house whose roof has fallen in. whose指物时,常用以下结构来代替(3)The classroom whose door is broken will soon be repaired.=The classroom the door of which is broken will soon be repaired.(5)Do you like the book whose color is yellow?=Do you like the book the color of which is yellow?注:that 用法(1)不用that的情况 (a) 在引导非限定性定语从句时。 (错)The tree, that is four hundred years old, is very famous here. (b) 介词后不能用。 We depend on the land from which we get our food. We depend on the land that/which we get our food from. (2) 只能用that作为定语从句的关系代词的情况 (a) 在there be 句型中,只用that,不用which。 (b) 在不定代词,如:anything, nothing, the one, all等作先行词时,只用that,不用which。 (c) 先行词有the only, the very,the same,the last,just修饰时,只用that。 (d) 先行词为序数词、数词、形容词最高级时,只用that,不能用which。. (e) 先行词既有人,又有物时。 (f) 先行词指物,在主句中作表语时. (g) 为了避免重复. (h)先行词是the way或the reason时,that可作关系副词,也可省略 (i) 主句的主语是疑问词who /which时 举例: Is this the book that you borrowed in the library? 这是你在图书馆借的那本书吗? Who that break the window should be punished. 谁打碎了窗户都要受到惩罚. All that is needed is a supply of oil. 所需的只是供油问题。 Finally, the thief handed everything that he had stolen to the police. 那贼最终把偷的全部东西交给了警察。 (三)、关系副词引导定语从句 关系副词 关系副词:在句中作状语 关系副词=介词+关系代词 why=for which where=in/ at/ on/ ... which (介词同先行词搭配) when=during/ on/ in/ ... which (介词同先行词搭配) 1. where指地点,在定语从句中做地点状语用来表示地点的定语从句。 (1) Shanghai is the city where I was born. (2) The house where I lived ten years ago has been pulled down. 2. when引导定语从句表示时间。在定语从句中做时间状语也可做连接词用 (1) I still remember the day when I first came to the school. (2) The time when we got together finally came.表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导。 By the time you arrived in London, we had stayed there for two weeks. 到你到达伦敦的时候,我们在那里已经待了两个星期。 I still remember the first time I met her. 我仍然记得我第一次见到她。 Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。 每一次他去出差,他带来了生活必需品,如毛巾,肥皂,牙刷等,很多。 3. why指原因 在定语从句中做原因状语 (1) Please tell me the reason why you missed the plane. (2) I don’t know the reason why he looks unhappy today. 注意:关系副词引导的从句可以由“介词+关系代词”引导的从句替换 (1) The reason why/ for which he refused the invitation is not clear, (2) From the year when/in which he was going to school, he began to know what he wanted when he grew up. 注:1)介词后面的关系代词不能省略。 2)that前不能有介词。 3) 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when ,where和why 互换。 This is the house in which I lived two years ago. This is the house where I lived two years ago. Do you remember the day on which you joined our club? Do you remember the day when you joined our club? This is the reason why he came late. This is the reason for which he came late. 宾语从句(一)宾语从句的种类宾语从句是一种名词性从句,在句中作及物动词的宾语,或介词的宾语,或形容词的宾语。根据引导宾语从句的不同连词,宾语从句可分为三类。1. 由that引导的宾语从句。that只有语法作用,没有实在的意义,在口语和非正式文体中可以省略。例如: He said (that) he wanted to stay at home. She doesn’t know (that) she is seriously ill. I am sure (that) he will succeed.2. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。例如: Do you know who (whom) they are waiting foe? He asked whose handwriting was the best. Can you tell me where the No.3 bus stop is? I don’t know why the train is late.3. 由if或whether引导的宾语从句。if和whether在句中的意思是“是否”。例如: I want to know if (whether) he lives there. He asked me whether (if) I could help him.(二)宾语从句的语序宾语从句的语序应为陈述句的语序。例如: I hear (that) physics isn’t easy. I think (that) you will like this school soon. Can you tell me how I can get to zoo? Please tell me when we’ll have the meeting.(三)宾语从句的时态1. 如果主句的时态是一般现在时,宾语从句该用什麽时态就用什麽时态。如: I don’t think (that) you are right. Please tell us where he is. Can you tell me how I can get to the railway station?2. 如果主句的时态是一般过去时,宾语从句只能用相应的过去时态(一般过去时, 过去进行时, 过去将来时,过去完成时)。例如: He asked what time it was. He told me that he was preparing for the sports meet. He asked if you had written to Peter. He said that he would go back to the U.S. soon.3. 如果宾语从句所陈述的是客观真理,其时态常用一般现在时。例如: Our teacher said that January is the first month of the year. Scientists have proved that the earth turns around the sun.状语从句状语从句状语从句用来修饰主句中的动词,副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句,地点状语从句,条件状语从句, 原因状语从句,结果状语从句,比较状语从句,目的状语从句,让步状语从句。1. 时间状语从句(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如:It was raining hard(rain hard 下大雨) when got to school yesterday.While he was doing his homework, the telephone rang.As he walked along(沿着走) the lake, he sang happily.He had learned a little Chinese before he came to China.After he finished middle school, he went to work in a factory.(2)在时间状语从句里,通常不用将来时态,用现在时态表示将来的动作或状态。例如:I’ll ring you up as soon as I get to New York.I will tell him everything when he comes back.He won’t believe it until he sees it with his own eyes.(3)在带有till或until引导的时间状语从句的主从复合句里,如果主句用肯定式,其含义是“一直到……时”,谓语动词只能用延续性动词。如果主句用否定式,其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如:The young man read till the light went out(熄灭).Let’s wait until the rain stops. We won’t start until Bob comes. Don’t get off(从下来) until the bus stops.【Till是指直到某一特定事件发生的时候,而在那个时刻之后,该事情或状况仍将持续。 Until是指直到某一特定事件发生的时候,而讲话的人在自己心里认为,在那个时刻之后,该事情或该状况将中止(不怎么可能持续)。固定组合里from morning till night,till/until是不能替换的,】2. 条件状语从句(1)条件状语从句通常由if, unless引导。例如:What shall we do if it snows tomorrow?Don’t leave the building unless I tell you to.(2)在条件状语从句里,谓语动词通常用现在时态表示将来的动作或状态。例如:I’ll help you with your English if am free tomorrow.He won’t be late unless he is ill.(3)“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。例如:Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late.Study hard and you will pass the exam. =If you study hard, you will pass the exam.3. 原因状语从句(1)原因状语从句通常由because, since, as引导。例如:He didn’t come to school because he was ill.As it is raining, we shall not (不得;不应该)go the zoo.Since you can’t answer the question, I’ll ask someone else.(2)because表示直接原因,语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题,只能用because。As和since语气较弱,一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。例如:------Why aren’t going there?------Because I don’t want to.As he has no car, he can’t get there easily.Since we have no money, we can’t buy it.(3)because和so不能同用在一个句子里。4. 结果状语从句(1)结果状语从句由so…that, such…that, so that引导。例如:He is so poor that he can’t buy a bike for his son.She is such a good teacher that everybody likes her.My pencil fell under the desk, so that I couldn’t see it.(2)so…that语such...that可以互换。例如:在由so...that引导的结果状语从句中,so是副词,与形容词连用。其结构是: “...so + 形容词(副词)+ that + 从句”。例如:He was so glad that he couldn’t say a word.The hall is so big that it can hold 2,000 people.Mother lives so far away that we hardly ever(几乎不,从来不) see her.在由such…that引导的结果状语从句中,such是形容词,它修饰的可以是单数或复数可数名词,也可以是不可数名词;名词前面可以带形容词,也可不带。如果是单数可数名词,前面需加不定冠词a或an。例如:It was such a hot day that nobody wanted to do anything.He had such long arms that he could almost touch the ceiling.(天花板)He made such rapid progress that he did very well in the mid-term. 有时上述两种结构是可以互换的。例如:It was such a wonderful film that all of us wanted to see it again.=The film was so wonderful that all of us wanted to see it again.It is such an important match that nobody wants to miss it.=The match is so important that nobody wants to miss it.(3)如果名词前由many, much, little, few等词修饰时,只能用so, 不用such。例如:Soon there were so many deer that they ate up all the wild roses.He has so little time that he can’t go to the cinema(去看电影) with you.5. 比较状语从句比较状语从句通常由as…as, 比较级 + than…等连词引导。例如:Tom runs faster than John does.This classroom is as big as that one.6. 目的状语从句(1)目的状语从句通常由 so that, in order that(为了,以便)引导。例如:We started early so that we could catch the first train.He studies hard so that he could work better in the future.We used the computer in order that we might save time.(2)so that既可引导目的状语从句,又可引导结果状语从句。区别这两种从句的办法有两个:1)目的状语从句里往往带有情态动词can, could, may, might等。2)从意思上看,目的状语从句往往表示的目的很明确。例如:Speak clearly so that they may understand you. (目的状语从句)Jack is badly ill so that he has to rest. (结果状语从句)7. 让步状语从句(1)让步状语从句通常由although, though等连词引导。例如:Though he is young, he knows a lot.Although I am tired, I must go on working.(2)although(though)不能用在同一个句子中。例如:我们不能说:Though it was raining hard, but he still went out.应该说:Though it was raining hard, he still went out.或It was raining hard, but he still went out.8. 地点状语从句 地点状语从句常常由where来引导。例如: Go where you like. Where there is a will, there is a way.总结:状语从句分类及常用连词: 类别 连 词 时间状语从句 when, whenever, while, as, before, after, since, till, once(一旦)地点状语从句 where, wherever 原因状语从句 because, since, as, for, now that(既然,由于)etc. (et cetera,等于and so on)目的状语从句 in order that(为了,以便), so that, that, etc. 结果状语从句 so…that, so that, such…that, that, etc. 条件状语从句 if, unless, as(so)long as, etc. 让步状语从句 though, although, even if, even though, however, whatever, as, etc. 比较状语从句 as…as, so…as, than, etc. 方式状语从句 as, as if, as though, etc.
详细的定语从句讲解
内容提要定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个成分,定语从句分为限定性和非限定性从句两种。状语从句分为时间状语从句,结果状语从句,让步状语从句,原因状语从句,条件状语从句以及行为方式状语从句。名词从句包括主语从句,宾语从句,表语从句和同位语从句及there be句型。 一、 限定性定语从句1. that即可代表事物也可代表人,which代表事物;它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略。而且,如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置 2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all, anything, much等,这时的that常被省略 4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语 5. where是关系副词,用来表示地点的定语从句 6. when引导定语从句表示时间〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导 By the time you arrive in London, we will have stayed there for two weeks. I still remember the first time I met her. Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc. 7. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格 8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时,常用there is来引导 二、非限定性定语从句:非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立 1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分 2. 在引导限定性定语从句时,that有时相当于in which, at which, for which或at which Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处。 I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反。 We arrived the day that(on which) they left. 刚好我们到的那天他们走了。 3. 有时as也可用作关系代词 4. 在非限定性定语从句中,不能用that,而用who, whom代表人,用which代表事物 三、定语从句结构错误 1. 缺关系词 2. 从句中缺成分摘自《简明英语语法》 在英文中,有两种定语从句:限定性定语从句与非限定性定语从句。这两种定语从句在其功能和形式方面都有明显的区别: 限定性定语从句限定性定语从句与主句的关系很紧奏,对其先行词起限定、修饰的作用。如果将其去掉,会影响句子意思的完整性;有时甚至于引起费解、误解。例如: Rainforests are being cleared for valuable timber and other resources to speed up the economic growth of the nationsin which they are located . 为了加速他们各自所在国家的经济发展,热带雨林作为有价值的原木和其他资源正为人们所砍伐。 Ocean currents affect the climates of the lands near which they flow. 洋流影响其流经的附近地区的气候。 They explained the reason to us why they had hated us before. 他们向我们解释为什么他们不喜欢我们的原因。 非限定性定语从句非限定性定语从句在形式上就与主句很松散,它与主句之间有一个逗点","隔开;它对其先行词没有限定、修饰的作用,只起补充、说明的作用。有时也用它来对全句进行补充、说明。即使将其去掉,也不会影响句子意思。由于上述原因,非限定性定语从句在表达意思方面也有别于限定性定语从句。另外,非限定性定语从句在中文译文里,我们往往将其作为一个分句处理,而不把它作定语翻译。 例如:Earlier , the Babylonians had attempted to map the world , but they presented it in the form of a flattened disc rather than a sphere , which was the form adopted by Ptolemy . (此句中,非限定性定语从句是对先行词a sphere进行补充、说明。) 更早之前,巴比伦人曾试图绘制世界地图,但是他们把它绘制成平盘状而不是托勒密所采用的球体状。 The combination of satellites, which transmit information , computers , which store information , and television , which displays information , will change every home into an education and entertainment center . (此句中,三个非限定性定语从句分别对三个先行词:satellites ,computers和television进行补充、说明。如果去掉这三个非限定性定语从句,那么句子可简化为: The combination of satellites , computers and television will change every home into an education and entertainment center .)卫星能传输信息,计算机能储存信息,电视能显示信息,把这些手段结合起来可以使每个家庭都成为教育娱乐的中心。 The sun heats the earth , which makes it possible for plants to grow .(此句中,非限定性定语从句是对全句进行补充、说明,将全句表达的意思看成"一件事情)。太阳给予大地热,这就使植物的生长成为可能。 The old man has a son , who is in the army .(此句中,非限定性定语从句是对先行词son进行补充、说明。但本句所传达的信息是:"这位老人只有一个儿子" 。如果将此句改写成限定性定语从句: The old man has a son who is in the army . 那位老人有一个在部队工作的儿子。那么,限定性定语从句就要对先行词son进行限定、修饰。这样一来,句子所传达的信息就变成了:"这位老人有一个儿子在部队工作,还有其他的儿子在干别的工作"。)那位老人有一个儿子,他在部队工作。
