语法讲解 时间状语从句的用法解析及练习

语法讲解时间状语从句的用法解析及练习 状语从句在复合句中作状语,其位置较灵活,可以在主句之前、之后或中间(放在句首时状语从句后面常用逗号,放在句末时状语从句前面往往不用逗号)。根据状语从句的含义,状语从句主要分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、结果状语从句、条件状语从句、让步状语从句等八种。掌握以上各种状语从句的关键在于把握其相应的引导词。以下是对时间状语从句的基本用法进行小结,希望可以帮助到同学们有一更深的理解。 时间状语从句的引导词 when, before, after, as, while, till/until, since,whenever 时间状语从句的用法 时间状语从句的引导词所表示的意思不尽相同,要注意把握不同的时间状语从句的引导词所表示的不同时间关系,以及它在具体句子中对应的对应时态、语态等问题。 1. when、as、while引导的时间状语从句分析: (1) when引导时间状语从句时表示“当……的时候”,when既可以指时间段也可指时间点,从句中既可用延续性动词又可用非延续性动词,且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。 注意体会如下例句:I’ll call you when I get there. 我一到那里就给你打电话。// When the wind blows, all the doors rattle. 只要风一吹,这门就吱嘎作响。// He stopped trying, when he might have succeeded next time. 他不再试了,其实他可能下一次就成功。// When I came home my wife was cooking dinner. 我回家时,妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同,而从句的谓语又是be动词时,那么从句中的主语和be可以省略;当when引导的时间状语从句的主语与主句主语相同时,往往还可以用“when+分词”的形式替代该状语从句。例如:When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。// When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候,我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”,它强调主句的动作与从句的动作同时持续地进行,用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词,或者主句的动作发生在从句动作的进行过程中,主句中的谓语动词通常是非延续性动词,例如:Study while you study; play while you play. 该学习的时候就学习,该玩的时候就玩。// I met her while I was at school. 当我在学校的时候我遇见了她。 (3) as引导时间状语从句时表示“当……时,一边……一边……”,侧重表示两个动作同时发生(包括一个主语同时进行两个动作),或者一种动作随着另一种动作的变化而变化。例如:He jumps as he goes along. 他边走边跳。// I slipped on the ice as I ran home. 我跑回家时在冰上滑了一跤。// I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。// As the wind rose the noise increased. 刮风的时候噪声增大。

英语让步状语从句用法总结

英语让步状语从句用法总结(一) 让步状语从句的用法一(表示“虽然,即使,尽管”) 1. although,though,even though,even if都表示“虽然,即使,尽管”之意,though 和although 语气较弱(其中的though 比although 通俗, 不如although 正式),even if和even though 带有强调意味而显得语气更强。例如:Although they are poor, they are happy. 虽然他们很穷,但很快乐。天气虽然很冷, 但他没有穿大衣就出去了。即使他们可能不会成功,但他们仍努力尝试。那篇文章虽然很短,但很重要。他好一点了,虽仍未痊愈。即使下雨,她也是走着去工作的。今晚我将去拜访他,即使我只能停留一小会儿。 注意:though 引导的让步状语从句的用法比较特殊,它可以倒装,也可以不倒装,具体用法参见as引导让步状语从句的用法。 2. as引导让步状语从句表示“虽然、即使、尽管”,其引导的让步状语从句必须采用倒装结构,as引导的倒装形式的让步状语从句的基本结构为:形容词/副词/名词(单数可数名词前一般不带冠词,有时也可见单数可数名词前形容词与不定冠词连用、形容词放在不定冠词前)/动词/过去分词+as+主语+谓语的其他部分。注意体会下列典型例句:Great as the author was, he proved a bad model. 这位作者尽管了不起,到头来却成了一个坏榜样。这个故事看似荒唐,却是真的。虽然他很富有,但他并不幸福。倒装时要省去单个名词前的冠词)尽管还是个孩子,他却能分辨黑白。他尽管勇敢,可见到蛇还是发抖。尽管伤势很重,他仍然十分乐观。虽然尽了最大努力,但是他仍然不能搬动那块石头。 [考题1]We had to wait half an hour ____ we had already booked a table. A. since B. although C. until D. before [答案]B [解析]下划线处之后所述的“我们已经预订了一桌”与前面所述的“我们已经不得不等了半个小时”之间语意相反,四个选项中although表示“即便……”,引导让步状语从句最为合适。 [考题2]____ most of the earth’s surface is covered by water, fresh water is very rare and precious.

A. his works are not widely read B. but his works are not widely read C. however his works are not widely read D. still his works are not widely read [答案]A [解析]英语不允许在连词although、though引导的让步状语从句之后的主句句首重复使用连词,如果要在复合句中强调某种特别的意义,可以在主句的句首加上yet、still等副词。例如:Although she has a lot of money, (yet/still) she is not happy. 虽然她很有钱,但是她并不快乐。
