2013 届高考英语二轮专题复习精品之必备词汇辨析(九) 1、if only, only if 由这两个词组引导的条件从句虽然都可以用来表示主句所需要的 "条件",但是两者在表 示说话人的语义意图方面却有差异。1. only if 引起的条件状语从句,是一个对“条件”限制更严 的“限制性条件状语从句”,表示“只有...(才);只有在...的时候,唯一的条件是...”的意思;与 if 引起的一般条件句相比,它有一种增强主句语势的作用。 例如:He will succeed only if he does his best.他只有尽力而为才能成功。I'll come only if you really need me.只有当你真正需要我的时候,我才来。Only if the case is urgent should you call out the doctor in the middle of the night.只有患者情况紧急时,你才可以在半夜叫医 生看病。 if only 引导的条件句,通常用来表示说话人对某事所寄予的某种强烈愿望,相当于 as long as。它可以独立使用,用来表示由于客观条件限制,为某事不大可能或完全不可能实现而感 到惋惜或遗憾的复杂心情,常用虚拟语气。 例如:If only I were as clever as you!要是我像你一样聪明该多好啊!If only you had not told Tom what I said, everything would have been all right. 要是你没有把我的话告诉汤姆就 好了,那样就不会出什么问题了。It is hard to avoid mistakes; if only they are conscientiously corrected, it will be all right.错误总是难免的,只要认真地改正,也就好了。 2、if, whether 这两个词都是指“是否”,用来表示犹豫不定,引出包含正反两面的疑问。 1).一般情况下两者可以替换使用,但 whether 显得正式一些。例如:I am not sure if/ whether the sports meet will be held tomorrow. 我不知道明天是否会举行运动会。 2).但在引导表语从句,同位语从句,在不定式之前,介词之后及句首时,只能用 whether。 如:The question is whether it is worth doing.问题是这样做是否值得。We had no idea whether he had gone without Jane.我们不知道他有没有带着简一起走。He doesn't know whether to accept the offer or not.他不知道该不该接受帮助。It depends on whether we have enough time to do it. 这取决于我们是否有足够的时间去做这件事。Whether he comes or not doesn't concern me.他来不来与我无关。 需注意,当 if 置于句首时,只能引导状语从句,表示“假如”,不能引导名词性从句。 3).倘若引导的是一个选择疑问句,则以用 whether 更为妥当。若要用 if 引导的话,if 和 or not 中间必须有词语隔开,不能连写。如可以说 I wonder whether/ if he has come or not. 不 可以说 I don't care if or not your car breaks down, 而须将 if 改成 whether。 4).有时用 if 可能会产生歧义,如 Tell me if you want the book.可有两种解释:“假如你 需要这本书,请告诉我”,或“请告诉我你是否要这本书”。若用 whether 的话,则只能作第二 种解释。 3、in addition, in addition to 这两个词组都可表示“除了,此外,另,又,还”等意思,用来表示两个事物或动作之间的 增补关系。但两者的语法功能和用法不同。 1)in addition 是一介词短语,作副词用,相当于词组 as well,其后不能跟名词或其他任 何成分,一般位于两个句子中间或位于句末。位于两句中时,常用一逗号与句子隔开。例如: There are many shops around the railway station. In addition, there are some newly-built hotelsthere.火车站附近有很多商店,此外,还有一些新建的旅馆。Aunt Mary gave us sandwiches for our picnic and a bag of cookies in addition. 玛丽舅母为我们去郊游准备了三 明治,另外还准备了一袋甜饼。 2) in addition to 是一短语介词,其后接名词或代词等作其宾语,意义大体相当 as well as 和 besides。如:In addition to English, he has to study a second foreign language. 除了英 语以外,他还必须学习第二外语。They have one hour to read newspapers in addition to their ordinary work. 除了日常工作以外,他们有一小时读报的时间。 4、ill, sick 这两个形容词都有“生病的,身体不适”的意思。 ill 作上述解释时,通常在句中作表语或补语,不作定语,它的后面可接 with 和 from 表示 原因。若 ill 作“坏的,恶劣的,邪恶的”解时,只能作定语。如:He has long been ill with high fever.他一直在发高烧。That ill woman killed her own daughter.那个坏女人杀了自己的女儿。 She became ill from anxiety.她由于焦虑而病倒了。 sick 和 ill 一样,可在句中充当表语或补语,但它还能作定语,保持原意义不变。它作表 语或补语时,另有“呕吐,恶心”的意思。sick 后可用 with 表示原因,用 for 表示“渴望”,用 of 表示“厌倦,厌恶”等。 如:She got 500 yuan a month for looking after the sick man. (此处的 sick 不能用 ill 代 替。)她照顾这个病人每月可赚五百元。My daughter was sick with a cold.我的女儿是因感冒 而病的。He began to feel sick as soon as the ship started to move.船一启航,他就开始晕船 了。The little girl is obviously sick for home.很明显,这个小女孩想家了。I am sick of his bad manners.他的不良举止真让我厌恶。The old man was sick of life, and wished he were dead. 那个老人对生活感到厌倦,真想死了算了。 5、intend, mean, propose 这组词都有“打算,有心做某事”之意。 intend:“打算,有...意向,意欲”,指经过考虑后打定主意要做某事或获得某物,常带有坚 定的决心。常跟不定式及其复合结构,常用短语:intend for 打算送给/供...使用;intend...as... 打算...He explained to her at length what he intend to do in the following week. 他详细地向 她解释了下周打算做什么。Having always been musical from an early age, the singer seems to have been intended for theconcert stage.那位歌手有音乐天赋,好像生来就是为了登台演 唱的。 mean:“打算,想象,有...意图”,不如 intend 正式,强调心里想做的意思,但不强调决 心,短语:mean...for 准备让...做...Everyone believed that it'll be a very suitable match because John and Julia were obviously meant for each other.每个人都认为他们的结合会很 般配,因为约翰和朱利亚显然是天生的一对。He shouldn't have done it, of course, but he was thoughtless.
