高中让步状语从句 及其练习题及其详解让步状语从句 - 概念 让步状语从句是状语从句中的一种,其本身也是状语从句。一般翻译为“尽管即使”就是我们日常生活中用的“退一步说”的感觉。 让步状语从句 - 使用的连词 引导让步状语从句的连词主要有以下这些:though, although, as; even if, even though; whether.or.; no matter+疑问词,疑问词-ever。 让步状语从句 - 用法 (1)though, although表示“虽然,纵然”之意。 这两个连词意思大致相同,在一般情况下可以互换使用。在口语中,though较常使用,although比though正式,二者都可与yet, still或never,the less连用,但不能与but连用。例如: Although/Though he was worn out, (still) he kept on working. 虽然他已经精疲力竭了,但仍然继续工作。 Although/Though he is very old, (yet) he is quite strong. 他虽然年纪大了,身体还很健壮。 值得注意的是,although引导的让步状语从句位于主句之前的情况较多,though引导的让步状语从句可位于主句之前或主句之后。例如: She passed the examination though she had not studied very hard. 她虽然不用功学习,考试却及格了。 (2)as, though表示“虽然但是”,“纵使”之意。 as引导的让步状语从句必须以部分倒装的形式出现,被倒装的部分可以是表语、状语或动词原形,though也可用于这样的结构中,但although不可以这样用。例如: Object as you may, Ill go.(=Though/Although you may object, Ill go.) 纵使你反对,我也要去。 Hard as/ though he works, he makes little progress. (=Though he works hard, he makes little progress.)尽管他学习很努力,但几乎没取得什么进步。 Child as/though he was, he knew what was the right thing to do.(=Though he was a child, he knew what was the right thing to do.)虽然他是一个孩子,但他知道该做什么。 Fast as you read, you cant finish the book so soon. 纵然你读得快,你也不能这么快读完这本书。 (3)even if, even though 表示“即使”,“纵使”之意,含有一种假设。 这两个复合连词的意思基本相同。它们常互换使用,但意义有细微差别。even if引导的让步从句含有强烈的假定性,而even though引导让步状语从句时,是以从句的内容为先决条件的,即说话人肯定了从句的事实。例如: Well make a trip even if/though the weather is bad. 即使天气不好,我们也要作一次旅行。 Even if he is poor, she loves him. (=He may be poor, yet she loves him.)即使他很穷,但她还是爱他。 Even though he is poor, she loves him. (=He is poor, yet she loves him.)尽管他很穷,但她还是爱她。 (4)whether.or.表示“不论是否”,“不管是还是”之意。 由这一个复合连词引导的让步状语从句旨在说明正反两方面的可能性都不会影响主句的意向或结果。例如: Youll have to attend the ceremony whether youre free or busy. 不管你忙不忙,都要参加这个典礼。 Whether you believe it or not, its true.无论你是否相信,这都是真的。 (5)“no matter+疑问词”或“疑问词-ever”的含义为“都;不管都” 它们引导的让步状语从句可以互换。例如: No matter what happened, he would not mind. (=Whatever happened, he would not mind.)无论发生了什么,他都不会介意的。 No matter who you are, you must keep the law.(=Whoever you are, you must keep the law.不管你是谁,你都要遵纪守法。 但“no matter+疑问词”结构只能引导让步状语从句,而“疑问词-ever”还可以引导名词性从句。例如: Whatever (=No matter what) you say, I wont believe you. (Whatever 引导让步状语从句)无论你说什么,我都不会相信你。 Ill eat whatever (no matter what) you give me. (whatever引导宾语从句)你给我吃什么,我就吃什么。 Whoever comes will be welcome. (Whoever 引导主语从句) 不管谁来都受到欢迎。 此外,有时while也可以引导让步状语从句,但一般要位于句首。例如: While I like the colour, I dont like the shape.我虽然喜欢那颜色,但不喜欢那形状。 综上所述,我们可以看出,学习让步状语从句的关键是关联词的选用;其次,要注意的是由as引导的让步状语从句要用倒装语序。 让步状语从句表示:虽然,尽管,即使等概念,由although, though(尽管,即使), however(无论怎样), whatever(无论什么), whoever(无论谁), whomever(无论谁), whichever(无论哪个), whenever(无论何时), wherever(无论哪里), whether(是否), no matter (who, what, where, when, etc) (无论), even if(即使), even though(即使)等词引导。 如: We wont be discouraged even if(=even though) we fail ten times.我们就是失败十次也不泄气。 It was an exciting game, though / although no goals were scored.那是一场精彩的球赛,尽管一个球都没进。(though, although不能与 but连用) Whether you believe it or not, its true.不管你信不信,这是真的。 However (=No matter how) expensive it may be, Ill take it.无论它有多贵,我也要买下它。 Dont let them in, whoever(=no matter who) they are.不管他们是谁,别让他们进来。 No matter what I say or how I say it, he always thinks Im wrong.无论我说什么或怎么说,他总认为是我错。while 后面接延续性行为,但这个动作肯定和主句动作时间不一样长。如:he was talking to me while he was watching the TV。应该说“看电视”比“谈话”时间长。而as通常两个动作一直相随,很可能时间相同。如:he was thinking of a question as watching the TV。这两个动作就是一直相随的。 as意为“一边一边”或“与同时”,重在表示动作同时发生、伴随进行。while只指“时间段”,不指“时间点”,从句的动词只限于持续性动词。 1 从句表示随时间推移连词能用as,不用while。 As the day went on, the weather got worse. 日子一天天过去,天气越变越坏。2 as引导短暂性动作的动词。Just as I stopped my car, a man came up to me.一致性 1、主句的时态(一般现在时,现在进行时,现在完成时);从句根据实际情况确定时态 2、主句:过去时态(一般过去时,过去进行时);从句:过去时态(一般过去时,过去将来时,过去完成时)不一致性1、主句的谓语动词与从句的谓语动词同时发生,从句的谓语动词用一般过去时或过去进行时 例如:He said he worked in a factory. My brother told me father was writing a letter then.2、从句的谓语动词发生在主句谓语动词之前,从句的谓语动词用过去完成时 例如:He said he had seen the film before. 3、从句的谓语动词发生在主句谓语动词之后,从句的谓语动词用过去将来时,过去将来进行时,过去将来完成时 例如:He said he would go with us. He said he would be visiting a freind of his the next morning. He said he would have learned 3000 Enlish words by the end of this term.4、如果宾语从句表示的是一般真理,就不受时态呼应的限制。时态是中考重点考察点之一,经过对全国各地中考题进行分析,我感觉对一般现在时的特殊用法(即在时间和条件状语从句中要求用一般现在时代替一般将来时来表示将来的概念)考察的频率特别高,下面我就来谈谈这个问题。 首先我们来翻译一个句子:如果明天不下雨的话,我们将参观公园。这是一个含有条件状语从句的复合句,主句动词visit和从句动词rain根据时间状语明天的提示,本来都应该用一般将来时,但是根据上面提到的那条规则,从句中的谓语动词不能用will not rain,而应该用一般现在时doesnt rain来表示将来,所以最后我们把这句话翻译成:We will visit the park if it doesnt rain tomorrow. 我们再来翻译一个句子:长大后我想成为一名教师。 这是一个含有时间状语从句的复合句,主句动词be和从句动词grow up本来都应该用一般将来时,但是根据上面提到的那条规则,从句中的谓语动词不能用will grow up,而应该用一般现在时grow up来表示将来。所以这句话我们要这样翻译: I will be a teacher when I grow up. 有了上面的两个例子,有的同学可能会这样总结:在if和when后的从句应该用一般现在时表示将来。这样看问题其实不全面,因为if和when又同时可以是连接主句和宾语从句的从属连词,请看下面两个例子: I dont know when he will come tomorrow. 我不知道他明天什么时候来。 I dont know if he will come tomorrow. 我不知道他明天是否会来。 以上两个例子中when后引导的不是时间状语从句,而是宾语从句,因为come是说明天发生的动作,在主句用一般现在时的情况下,从句依然要用will come来表示将来的意思;if后跟的也不是条件状语从句,而是宾语从句,所以依然要用一般将来时表示将来。 说到这里,我们就知道实际中考对这一规则的考察就是要求我们能够判断if和when后面的句子到底是宾语从句还是状语从句。那么如何进行正确的判断呢,我觉得可以从以下两个方面来考虑: 一、因为状语从句的位置可以变化,它既可以放在主句之前,也可以放在主句之后;而宾语从句的位置只能跟在主句的谓语动词之后(有时候主句的谓语部分可以是动词加介词构成,因为我们知道不及物动词加介词后,就相当于一个及物动词,可以带自己的宾语)。所以,如果我们能对if或when引导的从句的位置进行变化,那么我们就可以判断它们之后的句子是状语从句,从句中就只能用一般现在时来表示将来的概念;如果if或when引导的从句不能进行位置的变化,它们引导的就是宾语从句。 例如: We will visit the park if it doesnt rain tomorrow. = If it doesnt rain tomorrow, we will visit the park.(所以这个复合句中if引导的从句为条件状语从句。) I will be a teacher when I grow up.= When I grow up, I will be a teacher.(所以这个复合句中when引导的从句为时间状语从句。) 我们不能把 “I dont know when he will come tomorrow.”说成“When he will come tomorrow, I dont know.” 我们也不能把 “I dont know if he will come tomorrow.”说成“If he will come tomorrow, I dont know.” 所以这两个复合句的从句都是宾语从句。 一、根据意思来判断:if引导条件状语从句应该是“如果/假如”的意思,而if引导宾语从句的时候,往往应该翻译成“是否”;when在引导时间状语从句应该是“当时候”的意思,而when引导宾语从句,往往应该翻译成“什么时候”。 通过以上分析,同学们完全理解了这条规则吗?这条规则还可以进一步深入:在时间和条件状语从句中要求用一般过去时来表示过去将来的概念。在转述别人的打算时,我们往往要用这条规则。例如:1. He said he would go to visit the park if it did not rain the next day. 他说如果第二天不下雨的话他就去公园。2. He said he would be a teacher when he grew up. 他说他长大后将当一名教师。 下面请做一组题,看看自己掌握得如何?1. -Do you know ? -Next year.A. when he came here B. when did he come here C. when he will come here D. when will he come here (2003北京)2 Could you tell us ?A.when you will send the fridge to our house B.when will you send the fridge to our houseC.when you would send the fridge to our house D.when would you send the fridge to our house (2003河南)3 I dont know if he .

C know后接宾语从句。宾语从句部分谈及未来的事情,所以应该用一般将来时、陈述句词序。2. A 道理同上。本题的could应该理解为一般现在时,用could时语气比用can委婉。3. C 本题的第一处是宾语从句,第二处是条件状语从句。4. C 本题when后接时间状语从句,用一般过去时表示过去将来的概念。句子结构应该是多重复合句。第一个主句是He said,其后整个为其宾语。而且这个宾语是一个含有时间状语从句的复合句。5. C 第一处是条件状语从句,用一般现在时表示将来;第二处主句用一般将来时。6. A 条件状语从句,用一般现在时表示将来。7. C 条件状语从句,用一般现在时表示将来。8.
