英语状语从句讲解及练习题(附答案)

1、.（一）状语从句概述定义位置分类作用状语从句用作状语，是起副词作用的句子。状语从句可以放在主句之前，也可以放在主句之后，时间、条件、原因和让步状语从句放在句首时需要用 逗号和主句隔开。根据其作用可以分为时间、地点、原因、条件、目的、 让步、方式和比较等状语从句。它可以修饰谓语、非谓语动词、定语、状语和整个句 子。（二）状语从句详解 1. 时间状语从句引导词when用法意为“当的时候”。when引导从句的谓语动词可以是延续性动词，也可以是示例a liar is not believed when hespeaks the truth.说谎者讲真话 时也没有人相信。瞬间动词。并且 when 有wh

2、en he arrives, ill call you.while时表示“就在那时”意为“在的时候，在的同时”。while 引导从句的谓 语 动词 必 须是 延续性的，发生时间较长，并强when you laugh and smile, your body relaxes.while i was standing at the window, i saw several boys running along the street. while john was watching tv, his wife was cooking.asafterbefore.调主句和从句的动作同时发生（或者相对应

3、）。while有时还可以表示对比。意为 “一边 一边 ” 。 as引导的动作是延续性的，发生时间较短，一般用于主 句 和从 句 动作 同时发生；as 也可以强调一前一 后。意为 “ 在 之后 ” 。表示主句动作发生在从句动作之后。主句与从句的动作时间关系与 before 引导的从 句相反。意为 “ 在 之前 ” 。引导的从 句 不用 否 定形 式的谓语，并且当 before 引导的从句位于主句之后，有时译成 “ 就，才 ” 。当主句用将来时，从句总是用现在时；如果 before 引导的从句谓语用的是过去时，则the writer was angry as he was travelling o

4、n a train to london because someone had invadedhis “space”.he smiled as he stood up.with many hungry visitorswaiting, dont stay too long at your table after you have finished.if an early exit is necessary, you can leave after a scene is over.you cant watch tv before you finish your homework.before i

5、t ended, the theatre was almost empty.my father had left for canada just before the letter arrived.tilluntilsince.主 句 动词 多 用过 去 完成时，这样以便体现动作的 先后。意为 “ 直到 ” 。一般情况下可以和 until 互换。如果主句中的谓语动词是瞬时动词时，必须用否定形式；如果主句中的谓语动词是延续性动词时，用肯定和否定形式都可以，但表达 的意思不同。意为 “ 直到 ” 。在强调句型中多用 until。如果主句中的 谓 语动 词 是瞬 时动词时，必须用否定形式；如果主句中

6、的谓语动词是延续性动词时，用肯定和否定形式都可以，但表达的 意思不同。意为 “ 自从，从 以来 ” 。引导从句的谓语动词可以是延续性的动词，也可以s he didnt even know that it was an earthquake till she saw a shaking ( moving from side to side) light.s he fireman worked very hard till the fire was out.im waiting for my sister. iwont go to see my uncle until she comes.wait

7、 until i finish what i am doing.i have been studying hard since i entered the high school.it is four years since my sister lived in beijing.as soon as.是瞬时动词。一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时。但在 it is +时 间 +since 从 句 的 句 型中，主句多用一般现在时。意为 “ 一 就 ” 。引导时间状语从句时，如果主句用了将来时，从句一般使 用现在时。it is five years months

8、since our boss was not in beijing.tom will call me as soon as he gets home.i will call you as soon as i arrive.2.地点状语从句引导词where用法意为“哪里”。“where 引导的地点状语从句，（there+）主句”“哪里哪里就”。主句在从句后面时，there 可用可不用；主句在从句的前面示例where there is a will, there is a way.they were good persons. where they went, there they were wa

9、rmly welcomed. you should have put the book where you found it.wherever.时，一般都不用 there.意 为 “ 无 论 何 地 ” 。anywhere/wherever 引 导 地点 状 语 从 句 + 主 句 。anywhere 本身是个副词，但是常可以引导从句，相当于连词，意思相当于 wherever,anywhere 引导的从句可位于主句之前，也可以位于主句之后。而 wherever 本身就是个连词，表示 “ 在何处， 无论何处”。wherever the sea is, you will find seaman.i

10、ll go anywhere you go.3.条件状语从句引导词if用法连词，意为“假如，如果 ”。示例dont talkloudly at themeeting. if you do, you will.unless.当主句是将来时的时候，从句要用一般现在时。连 词 ， 意 为 “ 除 非 （ =ifnot ）。当主句是将来时的时候，从句要用一般现在 时。have to leave.well go for a picnic if itdoesnt rain this weekend.dont discuss the problems with your partner unless you

11、 are asked to do so.i wont go there unless you come with me.4.原因状语从句引导词assincebecause用法意为 “ 因为 ”。引导原因状语从句时表示附带。说明“ 双方已知的原因 ”，语气比 since 弱，较为正式，位置较为灵活（常放于主 句之前）。意为 “ 因为 ”。引导的原因状语从句一般放于主句之前表示已知的、显然的理由 （ 通 常 被 翻 译 成 “ 既然 ”），较为正式，语气比 because 弱。意为 “ 因为 ”。引导的原因示例as the weather is cold, i stay at home.as it

12、 is raining, youd better take a taxi.as you are tired, youd better rest.since the earth looks like a ball, the sun can shine on only half of it at a time.s ince the race is in april, i had to run throughout the winter, and in boston, winters are cold. since everybody is here. lets begin our meeting.

13、t he woman prefers winterbecause she can skate.for.状语从句一般放于主句之后，表述直接原因，语气较强，最适合 why 引导的疑问句。 because 引导的原因状语从句有时可以与because of 短语互换。意为 “ 因为 ”。引导的原因状语从句并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明，for 引导的原因状语从句只能放于主句之后，并且必须用逗号将其与主句 隔开。id like to collect stamps because they are interesting. im very tired these days be

14、cause of studying physics.he cant come because he is ill.= he cant come because of his illness.he must be ill, for he is absent today.he could not have seen me, for i was not there.5.目的状语从句引导词so that用法意为 “以至，以便 ”。目的示例try to speak loud enough so that状语的谓语常含有may,people can hear you clearly. mr. green

15、speaks very loudly soin orderthatmight, can, could, should, would 等情态动词。意为 “ 为了 ” ，相当于 sothat all the people can hear him clearly.we shall let you know the details soon in order that you.that. in order to 后面可以跟动词原形构成目的状语，不是目的状语从句。can/may make a arrangements.6.结果状语从句引导词sothatsuch.that用法意为“如此以至于”。so+

16、adj./adv.原级+that, so 是副词，只能修饰形容词和副词。so 还可与表示数量的形容 词 many, few, much,little( 这四个形容词表示多或少时 ) 连用 , 形成固定搭配。so+ many 或 few+复数可数名词+that; so+ much 或 little+不可数名词+that.意为“如此以至于”。有三种结构：such+a(an)+adj.+单 数 不 可 数 名 词 +that;such(+adj.)+ 不 可 数 名 词+that; such( + adj.) + 复数可数名词 +that, such 是形容示例this year it has ra

17、ined so heavily in south china that lots of problems are caused. the ice on the lake was sothin that people couldnt skate on it.too often, we spend so much time thinking about the future that we fail to enjoy the present.there are so few notebooks that i cant give you any.its such a wonderful song t

18、hat we all like it.s imon is such dishonest person that no one believes him.t he boy is so young that he cant go to school.= he is such a young boy that he.词，修饰名词或名词词组。有时可与 sothat 句型转 换。cant go to school.7.让步状语从句引导词thoughalthough用法意为“虽然”。不能和 but 连用。但是可以同 yet(still)连用，构成 thoughyet(still).though 较普遍，常

19、用于非正式的口语和书面语中。 even能和 though 组合表示强调，在 这 里 even though=evenif(no matter if; though 即使也)。though 可以独立用作副词，常放在句末，意为 all the same(还是；仍然 )或 however(可是；然而 )。意为“虽然”。不能和 but 连示例so it has lived up to now though it isnt strong at all. though they are twinbrothers, they dont look like each other.even if/ even t

20、hough we could afford it, we would afford it, we wouldnt go abroad for our vacation.although he died several years ago, i can still.用。但是可以同 yet(still)连用，构成 althoughyet(still).although 较为正式，语气比though 重，常用以强调让步概念。 even 不能和 although 组合。remember the days we spent together and what he has taught me about

21、 love. although we had little food with us, we decided to spend the night in the car.8. 比较状语从句引导词asas.not as /soas用法意为 “ 和 一样 ” 。表示同级的比较。使用时要注意第一个 as 为副词，第二个as 为连词。其基本结构为：as+adj./adv.原级 +as。若有修饰成分，如 twice, threetimes, half, a quarter 等，则须置于第一个 as 之前。意为“和不一样，不如”。也表示同级比较。示例she is very good at painting

22、. she can paint as well as here teacher.i ran out as quickly as possible.s he is not so (as ) outgoing as her sister.t his dictionary is not as/so useful as you think.9.方式状语从句.引导词as/(just)as.soas if/ as though.用法意为“犹如，就像”。引导的方式状语从句通常位于 主 句 后 ， 但 在(just)as.so 结构中位于句首，这时 as 从句带有比 喻 的 含 义 ， 意 为 “ 正如 ，就

23、像 ” ，多用于正 式文体。意为“就像，好像”。两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。常译作 “ 仿佛 似的，好像 似的”。示例when in rome, do as the romans do.as water is to fish, so air is to man.if would never forget here smile, or the way her eyes shone as if we were the same age.it looks as if the weather may pi
