高中英语语法知识重难点

高中英语难点词语使用解释 一,使用代用词one应注意的问题 英语中one可用作代用词.它代替上文出现的名词词组中心词,以避免重复.使用代用词one时需注意以下几个方面: 1.只能代替可数名词,不能代替不可数名词.eg: I haven't got a raincoat.I'll have to buy one. Brown's old car is much better than our new one. 2.复数名词的代用词为ones.eg: He ate all the big cherries and left me the little ones. There was a mother bird in the nest and there were four young ones. 3.代用词one的常用关联情况 1)与前面带有冠词的形容词连用.eg: We are moving from our present house into a smaller one. Have you any knives I need a sharp one. I like a strong cup of tea better than a weak one. I propose in this chapter and in the following one to give an outline of the pioneering work. 2)与形容词性物主代词和形容词连用.eg: Take off your blue dress and put on your green one. 3)其前有定冠词,其后有后置修饰语(形容词短语或定语从句).eg: If you can't find your pen, use the one on the table. Hand me my coat,please.It is the one hanging on the third hook. Of the two watches, I prefer the one that you showed us first. 4)与this和that连用,其后可接后置修饰语或定语从句.eg: You sit in that chair,and I'll have this one. The book I am referring to is that one on the second shelf. The most valuable ring that l possess is this one I am wearing. 5)其前可用广义序数词,如next,1ast, other,another及疑问代词which等.eg: Let's finish this exercise so we can go on to the next one. Some of the answers were correct,but I don't remember which ones. 6)在口语中,代用词one常与形容词最高级连用.eg: Betty had tens of thousands of Augustus's 1etters. She chose from these thousands the fifteen most damaging ones she could find. 4.代用词one(或ones)的省略 1)句中形容词表示前后对比时,可以省略代用词.eg: His professional instincts are stronger than his personal (ones). Local political forces are 1ess concentrated than national(ones). There are,of course,bad architects as well as good(ones). Anglo—Saxon should be preferrted to foreign words,and the short word to the long (one). 2)句中只提到两种可能性时,一般省略代用词.eg: The new library will be like the o1d(one). Lean years may be expected to follow the fat(ones). 3)形容词比较级后常省略代用词.eg: I know this is not quite the right word,but I can't be bothered to think of a better (one). There were two tables 1aid…he and Ann were expected to preside at the smaller (one). 4)"不定冠词+原级形容词"后的代用词一般不省略.eg: Have you any knives I need a sharp one. 5.不使用代用词的场合 1)one不可用来代替不可数名词或集合名词.以下各句中省略的均不是代用词one.eg: I'd prefer the red wine to the white (wine). It is cheaper to buy old furniture than to have new (furniture) made. 2)one一般不能与own连用.eg: I can't write properly with your pen;I'd rather use my own.(不能用my own one) Mrs Smith is both 1oved and respected in many countries besides her own.(不能用 her own one) 3)one不能置于所有格名词或形容词性物主代词之后.eg: As my own bicycle was broken,I borrowed John's.(不能用John's one) Is this my pen,or is it yours (不能用your one) 如需连用,所有格名词或形容词性物主代词与代用词之间必须有一形容词,如John's old one,your new one,my best one等.eg: You may borrow my o1d pen,if you wish,but I cannot 1end you my best one. My humble fate is curiously bound up with John's illustrious one. 4)one不能与these和those连用.eg: I don't care for those flowers;I would rather have these. These machines are better than those we turned out last year. 5)one不能与基数词连用.eg: You have three book; I have only two.(不能用two ones) 但在口语中有时可以例外.eg: There were a 1ot of artistic kinds of people there,and one or two ones from the BBC. 二,"to...to"结构之肯定意义的语域 及其成因研究 "too…to"是英语中常见的,以其肯定形式表示否定意义的结构.但是,并不是所有的"too…to"结构都表示否定意义.在某些情况下,"too…to"结构也表示肯定意义.下面将从"too...to"结构的语义特征分析其肯定意义及其语域和成因. 一,"too...to"结构的肯定意义在"

某些特殊副词+too…to"结构语域中的体现及其成因研究: 1.语域研究 "too...to"结构之前带有"but,only,all,simply,just"时,该结构表示强烈的肯定意义,汉译为"非常/十分/实在/真是太……"等.eg: They are but too glad to do so.他们非常喜欢这么做. The patient was only too willing to be operated upon.病人非常愿意接受手术. We are all too satisfied to take your advice.我们非常乐意接受你的建议. We shall be simply too glad to help you.我们很乐意帮助你. I am just too glad to help you.能帮你的忙,我真是太高兴了. 2.成因研究 在以上例句中,too前面的"but,only,all,simply,just"等副词只起到了加强语气的作用.因此,用于"too...to"结构前面的这几个副词可以互换,而不定式,to则表示原因,有肯定意义.另外,该用法中的too只表示程度深一些,所以不会对其后的形容词产生否定意义,反而更强调了其肯定意义. 二,"too...to"结构的肯定意义在"否定副词+too...to"结构和"too...+not to"语域中的体现及其成因研究 1.语域研究 "too...to"结构前也可以加否定副词not或never构成"not/never too…to"和"too...not to"结构.该结构不表示否定,而表示肯定,译为"不太……可以……,决不……能……,非常(很,太,那么)……不会不(必定能,所以能)……".eg: He is not too weak to carry the bag.他不太弱小;可以背得动那个书包. The box is not too heavy to lift.这只箱子不太重,可以抬得起来. It is never too late to mend.亡羊补牢,犹未晚也. One is never too old to learn.活到老学到老. He is too careful not to have noticed that.他那么小心,肯定会注意到那一点的. You are too kind not to help me.你很善良,肯定会帮助我的. 2.成因研究 当too表示"太,过分"意义时,它是一个表示超量的程度副词,对其后所跟的形容词起一种消极作用,含有否定意义,因此就导致了"too…to"结构含有否定意义.但如果在too前加否定词not或never,形成双重否定,则能使原来具有否定意义的"too...to"结构转化为肯定意义. 三,"too…to"结构的肯定意义在"too+特殊形容词+to"结构语域中的体现及其成因研究 1.语域研究 有时可以在too之后加表示某种心情或描绘性的形容词,表示肯定意义.这类形容词有"glad,pleased,happy,satisfied,ready,apt,incline,kind,eager"等.eg: He is too ready to help others.他十分乐意帮助别人. He is too inclined to be cheated.他很容易上当受骗. Beginners are too apt to make mistakes in grammar.初学者极易犯语法错误. He is too eager to know the result of his experiment.他迫切想知道他所做的实验结果. It is too kind of you to repair the car for me.你为我修车真是太好了. He is too p1eased to receive the pretty gift.收到这件漂亮的礼物,他真是太高兴了. 2.成因研究 在以上例句中,表示心情或描绘性的形容词和to引导的不定式结合成一个表示不可分割的状态,态度,心境或倾向,并且具有明显的动词意义或感情色彩.因此,句中的不定式"to..."表示肯定(不表示结果)含义. 可见,在"too...to"结构表示肯定的句型中,too的逻辑意义为…'extremely'(很,十分),强调其后的形容词具有肯定意义;这与"too...to"结构表示否定时,too的含义和作用完全相反. 三,as用法小结 as一词在SEFC新教材中多处出现.它词性多,词义广,用法灵活.现将其用法归纳如下. 一)as作副词,表示程度,意为"同样地".在"as...as...","not as...as..."结构中的第一个as是副词,作"和/与...(不)一样"解.eg: Jack is as tall as his father.杰克和他的父亲一样高. He doesn't speak English as/so fluently as you.他的英语说得不如你流利. 二)as作介词. 作"如,像"解.eg: They got united as one man.他们团结得像一个人一样. She spoke of me as her dearest friend,她谈起我犹如我是她最亲密的朋友. 2.作"充当,作为"解.eg: As a writer,he was famous.作为作家,他是很有名的. English is spoken as the first language by most people in Australia.在澳大利亚,大多数人把英语作为第一语言. 三)as作连词,常用来连接主句和状语从句. 1.引导时间状语从句,作"当...的时候"解,有"随着..."之意,与while意义相近,强调两个动作同时发生;或某事一发生,另一事立即发生.eg: He shouted aloud as her ran along.他一边往前跑,一边高声地呼喊. I was startled as he opened the door.他一开门,我吓了一跳. We get wiser as we get older.随着年龄的增长,我们会变得更聪明. as作连词,相当于when.eg; As a little boy (When he was a little boy)he began to learn to play piano.

他小时候就开始学弹钢琴. As a child (When he was a child),he lived in the countryside.他小时候住在农村. 2.引导原因状语从句,作"因为,由于"解,与because的用法相近.eg; As it was getting very late,we soon turned back.因为很晚了,我们很快就回来了. I must stop writing now,as I have rather a lot of work to do.我必须停笔了,因为我还有许多工作要做. 3.引导方式状语从句或比较状语从句,作"正如,(如)像"解.例eg: As in your country,we grow wheat in the north and rice in the south.正如(像)你们国家一样,我们在北方种小麦,在南方种大米.(方式状语从句) When at Rome,do as Romans do.入乡随俗.(方式状语从句) They always work as hard as we do.他们工作总是像我们一样努力.(句中第二个as是连词,引导比较状语从句) 此外,在"as…as possible"结构中第二个as也起连词的作用.eg: Read the story as quickly as possible.(=Read the story as quickly as you can.)尽快地阅读这个故事. They watered the trees as often as possible.(=They watered the trees as often as they could.)他们尽可能经常给树浇水. 4.引导让步状语从句,作"虽然,尽管"解.这时从句常用倒装语序,即把从句中的表语,状语或动词原形放在as之前.eg; Strange as it may seem,it is true.尽管这事看上去很奇怪,但却是真的. Try as he might,Tom could not get out of the difficulties.不管怎样努力,汤姆还是摆脱不了困境. Child as she is,she knows a lot.她虽然年幼,但却懂得很多东西.(注意;child前不带不定冠词a) 四)as作关系代词. 1.引导限制性定语从句,用在"such...as","the same...as","as...as"等结构中,常译作"像...一样的人(或物)","凡是...的人(或物)".例eg: He wished to be such a man as Lei Feng was.他曾希望做一个像雷锋那样的人. My hometown is no longer the same as it was.我的家乡再也不像过去一样了. As many people as are present will be given a present.所有在场的人都将得到一份礼物. 2.引导非限制性定语从句,用来指代它前面的整个句子(即先行句),意思是"这一点".这个分句可以位于句首,句中或句末.eg: As is well known,oceans cover more than 70% of the earth.我们知道,海洋占地球面积的百分之七十以上. This elephant is like a snake,as anybody can see.谁都看得出来,这头大象就像一条蛇. 五)含as的固定词组的用法 1.as soon as作"一…就"解,引导时间状语从句.eg: As soon as I get to Beijing,I'll write to you.我一到北京,就给你写信. 2.as/so long as作"只要"解,eg; As/So long as you study hard,you'll make progress.只要你努力,你就会取得进步. 3.as if/though常用来引导方式状语从句,作"好像,仿佛"解.如果从句中讲的是非真实情况,则用虚拟语气.eg: She loves the child as if/though he were her own.她爱这个孩子如同爱自己的孩子. They talked as if/though they had been there,他们谈起话来就好像他们真的到过那里似的. As if/though也可用来引导表语从句,常用在"It appears/looks/seems...+as if/though"句型结构中.eg; It appears as if/though it is going to clear up.看起来天要晴了. It seems as if/though he knew nothing about it.他好像对此事一无所知. 4.as to作"关于,至于"解.eg; There is no doubt as to his honesty.他的诚实是无可置疑的. 5.as much/many as作"多达...","达到...之多"解.eg: The number of people who lost homes reached as many as 250000.无家可归的人数 达25万之多. He can earn as much as 5000 dollars a month.他每月能挣5000美元. 6.so/as far as I know作"就我所知"解,在句中作插入语.eg: As/So far as I know,he will come here next Monday.据我所知,他将于下星期一到这里来. 7.as a result,as a result of表示"由于...的结果".eg: We follow up the suggestions,and have had satisfying experiences as aresult.由于我们按照建议办事,因此一直得到满意的结果. She died as a direct result of the accident.她的死是那次事故的直接结果. 8,as well为"也,还"之意.eg: Come early,and bring your brother as well.早点来,把你的弟弟也带来. as well as也可以作"和,同"解.当其连接两个并列主语时,谓语动词应与前面的主语在数上保持一致.eg: My parents as well as my elder sister enjoy music. 比较:My elder sister as well as my parents enjoys music.我父母亲和我姐姐都喜欢音乐. 9.so as to,so...as to若跟动词原形,表示目的或结果.eg: He studied hard so as to pass the exam.他努力学习以便通过考试.(表示目的) He was

so strong as to carry the heavy box.他很强壮,能搬动这个沉重的箱子.(表示结果) 四,keep,1eave,find,feel和make 在S V O C中的用法 SVOC是一种基本句型.其中S-Subjeet,V-Verb,O-Object,C-Complement. 宾语补语可以是形容词(Adjective),名词(Noun),现在分词(Present participle),过去分词(Past participle),介词短语(Prepositional phrase)和副词(Adverb),也可以是动词不定式(Infinitive),或是从句(Clause).SVOC结构在SEFC中运用很广泛,而且动词make, keep,leave,find和feel在新教材中出现频率很高,也是学习中的难点.下面分别谈谈这些词在SVOC中的用法.
