高中英语高考复习易错词汇短语辨析(共七组)
展开高考英语易错词汇短语辨析一、travel, trip, journey 三者均可表示“旅行”,区别如下:1.travel 泛指一般意义的旅行,是不可数名词。如:He is fond of travel (= travelling)。他喜欢旅行。Travel is much cheaper than it used to be.现在旅行比过去便宜多了。注:有时可用复数形式,主要指时间较长的各处旅行,此时通常有物主代词修饰,但是尽管用了复数形式,却不能与 many 或数词连用。如:He‘s gone off on his travels again.他又外出旅行了。另外,travel 通常只是泛指旅行,而不特指某次具体的旅行,所以通常不说:How was your travel?2.journey 通常指远距离的陆地旅行,并且不一定要返回到出发地(即通常指单程)。如:I wish you a pleasant journey.祝你一路顺风。He made a journey to Beijing.他去北京旅行了。注:journey 有时并不指真正意义的“旅行”,而只是表示走过一段距离。如:How long is your journey to work?你上班要走多远?3.trip 通常指近距离的为了办事或消遣而进行旅行,并且往往要回到出发点(即指双程),不过有时 trip 也可指远距离的长途旅行,可与 journey 换用,比 journey 更通俗。如:A:Where is John?约翰在哪里?B:He‘s on a trip to Shanghai.他去上海旅行了。He‘ll make a round-the-world trip.他将周游世界。二、affect, effect, influence 【区别一】affect 与 effect 均可表示“影响”,其区别是:前者是动词(及物),主要指一时的影响,着重影响的动作,可指一般意义的影响(不分好坏),也可指不良影响;后者是名词(可数或不可数),两者的关系大致为:affect=have an effect on.如:To affect a policy is to have an effect on it.影响一项政策就是对该政策具有一种影响。The news did not affect her at all.=The news had no effect on her at all.这条消息对她没有一点影响。注:effect 有时虽用作动词(及物),但不表示“影响”,而表示“实现”或“产生”等。如:They effected their escape in the middle of the night.他们半夜逃脱了。He effected great changes in the company.他使公司发生了巨大的变化。【区别二】influence 表示“影响”,主要指对行为、性格、观点等产生间接的或潜移默化的影响。可用作动词(及物)或名词(通常不可数,但有时可连用不定冠词)。如:What you read influences your thinking.你读的东西对你的思想有影响。Television has a strong influence on people.电视对人有很大的影响。It‘s clear that her painting has been influenced by Picasso.她的画显然受了毕加索的影响。三、aloud, loud, loudly 1.aloud的用法aloud 只用作副词,不用作形容词,注意以下用法:(1) 强调“出声”,即把话说出来,而不是在心里默默地“说”,通常与动词 read, speak, think 等动词连用。如:read aloud 朗读 think aloud 自言自语地说(2) 表示“大声地”,通常与动词 cry, laugh, shout, call 等动词连用,如:The boy is crying aloud.这男孩子在大声哭。She called aloud for help.她大声呼救。2.lould的用法loud 表示“大声”或“响亮”,可用作形容词和副词:(1) 用作形容词。如:He has a loud voice.他嗓子大。The music is too loud;please turn it down.这音乐太吵人了,请把音量关小一点。(2) 用作副词(与 loudly 同义),一般只与动词 speak, talk, laugh, sing 等连用,且必须放在这些动词之后。如:I can‘t hear you, please speak louder.我听不见,请说大声些。3.loudly的用法loudly 只用作副词(与用作副词的 loud 同义)。如:Don‘t talk so loudly [loud].别这么大声讲话。注:loudly 比用作副词的 loud 使用范围更广,它除与 speak,talk,laugh 等动词连用外,还可与其他表示声响的动词连用,且可以放在这些动词之前或之后。如:The man snored loudly.这个人鼾声打得响。He heard a cocklock loudly crow.他听见雄鸡大声啼叫。另外,在用于比较级或最高级时,通常用 loud,而不用 loudly.如:Who laughed loudest?谁笑的声音最大?in the air与on the air1.in the air 在空中;在流传中;渺茫。如:Birds fly in the air.鸟在空中飞。There was thunder in the air.天上打着雷。The plan is quite (up) in the air.计划还相当渺茫。Look, hold it uP in the air like this.看着,像这样把它举在空中。2.on the air 在广播中。如:The show is on the air.演出正在转播。I heard the news on the air.我在广播中听到了这条消息。What‘s on the air this evening?今晚有什么广播节目?The show is on the air at seven o‘clock.这次演出七点钟播出。四、until与till 用作介词或连词,意为“直到(……为止”,两者常可换用,只是 until 比 till 稍正式,所以在正式文体中,一般用 until,而在口语或非正式文体中则两者都可用。从其后所接成分来看,till多与名词或较短的从句连用,而较长较复杂的成分多用 until,位于句首时也多用 until.两者在用法上应注意以下几点:1.相关主句谓语必须是持续性动词,若是终止性动词,则应为否定式(因为终止性动词一旦被否定就成为状态,便可持续)。如:We waited until [till] he came.我们一直等到他来。We didn‘t leave until [till] he came.直到他来我们才走。2.引导时间状语从句时,其谓语要用现在时表示将来意义。如:I won‘t leave until he comes back tomorrow.我要等他明天回来再走。3.有时其后可跟副词、介词短语或从句等。如:He has been ill until recently.他最近一直生病。She didn‘t return until after twelve o’clock.直到 12 点过后她才回来。They didn‘t reach the station until after the train had left.直到火车开走之后,他们才到达车站。Until when are you going to stay here?你在这儿要待到什么时候?before long与long before1.before long 的意断是“不久,很快”。如:I‘ll be back before long.不久我就回来。Before long he got married.不久他就结婚了。2.long before有两个用法:(1) 老早,早就(单独使用,表示比过去某时早得多的时间)。如:She had left long before.她老早就离开了。That had happened long before.那事老早就发生了。注:long ago 表示“很久以前”,指的是从现在算起的很久以前,通常与一般过去时连用:I met him long ago.我很久以前就认识他了。(2) 在……的很久以前,在还没有……的很久以前。如:She had left long before his return [he returned].在他回来的很久以前她就走了。He had worked in the factory long before he got married.在他还没有结婚的很久以前他就在这家工厂工作了。注:此时的主句谓语通常用过去完成时,但有时也可用一般过去时(因为 before 已体现了动作的先后关系)。如:This happened long before you were born.这事在你还没出生以前很久就发生了。另外注意以下句式:It is [was, will be] long before……在……前需要很久。如:It was long before he came back.过了好久他才回来。It won‘t be long before we see each other.不久我们又会见面的。比较:It wasn‘t long before he realized his mistake./ Before long he realized his mistake.不久他意识到了自己的错误。五、agree with, agree to和agree on(1)agree with的意思是“同意”,“赞成”。后面常接表示人或意见(看法)的名词或代词作宾语。如:Does she agree with us?她同意我们的意见吗?None of us agree with what you said.我们没有一个人同意你讲的话。(2)agree with还有“与……一致”,“(气候、食物等)适合”的意思。如:His words do not agree with his actions.他言行不一致。Too much meat doesn‘t agree with her.吃太多食物对她身体不合适。注意:agree with不能用于被动语态。(3)agree to意为“同意”,“赞成”,后面跟表示“提议”,“办法”,“计划”,“安排”等的名词或代词。如:Please agree to this arrangement.请同意这个安排。This plan has now been agreed to.这个计划已经被认可了。(4)agree on表示“对……取得一致意见”,指两方或多方就某个问题取得了一致的意见或是达成了某种协议。如:After discussion the two sides agreed on a cease-fire.经过讨论,双方就停火问题达成了协议。They all agree on the matter.他们在这个问题上意见一致。 六、besides,but,except 1.基本区别三者都可表示“除外”,但 besides 表示一种累加关系,意指“除了什么之外,还有……”;而 except 或 but 则表示一种排除关系,意指“除了什么之外,不再有……”。如:Besides his wife,his daughter also went to see him.除他妻子外,他女儿也去看过他(即妻子女儿都去看过他)。Nobody went to see him except [but] his wife.除他妻子外,没有一个人看过他(即只有他妻子去看过他)。注:在否定句中,besides 也表示“除……之外不再有…… ”,与but, except 同义。如:No one passed the exam besides [except] Jim. 除吉姆外,没一个人通过考试。 2.关于 but 与 except(1) 两者都可表示“除……外不再有……”,但含义上略有差别:but侧重指意义的几乎完整性,而 except 则侧重指后面除去的部分。比较:All are here but one.除一个人都到了。All are here except one.还有一个人没到。(2) 在现代英语中,but 的介词用法十分有限,一般说来,它只能用在下列词语之后:① no, no one, nobody, nothing, nowhere 等② any, anyone, anybody, anything, anywhere 等③ every, everyone, everybody, everything, everywhere 等④ all, none 等⑤ who, what, where 等Everyone knows it but you.除你之外大家都知道。I haven't told anybody but you.除你之外,我没告诉任何人。No one but he [him] showed much interest in it.除他之外没有一个人对此有很大兴趣。一般说来,若没有出现上述词汇,就不宜使用介词 but, 否则可能造成错句。但是 except 却没有以上限制。比较:正:The window is never opened except in summer. 除夏天外,这扇窗户从不打开。误:The window is never opened but in summer.(3) but 一定不能用于句首,except 通常不用于句首:除我之外每个人都累了。正:Everyone is tired but (except) me.正:Everyone but (except) me is tired.误:But (Except) me, everyone is tired.注:except for 可用于句首,表示 except 的意思:正:Except for me, everyone is tired.七、no more than (一)no more than 与 not more than1.no more than 的意思是“仅仅”“只有”“最多不超过”,强调少。如:This test takes no more than thirty minutes.这个测验只要30分钟。The pub was no more than half full.该酒吧的上座率最多不超过五成。For thirty years, he had done no more than he (had) needed to.30年来,他只干了他需要干的工作。2.not more than 为 more than (多于)的否定式,其意为“不多于”“不超过”。如:Not more than 10 guests came to her birthday
