初中状语从句讲解及习题附答案

（一）状语从句概述定义 状语从句用作状语，是起副词作用的句子。位置 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。分类 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。作用它可以修饰谓语、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用法示例精品资料when意为“当 的时候”。when引导从句的谓语动词可 以是延续性动词，也可以是瞬间动词。并且when 有时表示“就在那时”a liar is not believed when hespeaksthetruth. 说谎者讲真话时也没有人相信。when he arrives, i ll call you. whenyoulaughandsmile, your body relaxes.while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while i was standing at the window, i saw several boys running along the street.的，发生时间较长，并强调主句和从句的动作同 时发生（或者相对应） 。while有时还可以表示对比。whilejohnwaswatching tv, his wife was cooking.as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。the writer was angry as he was travelling on a train to london because someonehad invaded his “space ”. he smiled as he stood up.after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。withmanyhungryvisitorswaiting, don t stay too long at yourtableafteryouhavefinished.if an earlyexitis necessary, you can leaveafter a scene is over.before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youcan twatchtvbeforeyou finish your homework. beforeit ended,thetheatre was almost empty.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，则主句动词多用过去完成时， 这样以便体现动作的先 后。my father had left for canada just before the letter arrived.till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。she didn t even know that it was an earthquake till she saw a shaking ( moving fromside to side) light.the fireman worked very hard till the fire was out.until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im waiting for my sister. i won t go to see my uncle until she comes.wait until i finish what i am doing.思不同。since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。i have been studying hard since i entered the high school.it is four years since mysister lived in beijing.it is five years months since our boss was not in beijing.as soon as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。tom will call meas soon as he gets home.i willcallyouassoonasiarrive.2. 地点状语从句引导词用法示例where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wherethereisawill, there is a way.theywere good persons. wheretheywent,there不用；主句在从句的前面时， 一般都不用 there.theywerewarmly welcomed.youshouldhaveputthebook where you found it.wherever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”。whereverthesea is, you will find seaman.ill go anywhere you go.3. 条件状语从句引导词用法示例if连词，意为“假如，如果”。当主句是将来时的时候， 从句要用一般现在时。don ttalkloudlyatthe meeting.ifyou do,youwillhave to leave.we llgoforapicnicifitdoesn t rain this weekend.unless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。don t discusstheproblems with your partner unless youare asked to do so.i won t go thereunlessyou come with me.4. 原因状语从句引导词用法示例as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）。as the weather is cold, i stay at home.as it is raining, youd bettertake a taxi.asyouaretired,you d better rest.since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。since the earth looks like a ball, the sun can shine on only half of it at a time.since the race is in april, i had to run throughout the winter, and in boston, winters are cold.sinceeverybodyishere. lets begin our meeting.because意为“因为。”引导的原因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。the woman prefers winter because she can skate.id like to collect stampsbecausetheyare interesting.im very tired these daysbecause of studying physics.he can t come because he is ill. = he can t come because of his illness.for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。hemustbeill,forheis absent today.he could not have seen me, for i was not there.5. 目的状语从句引导词用法示例so that意为“以至，以便”。目的状语的 谓 语 常含 有may, might,can,could,should,would等情态动词。try to speak loud enough so that people can hear you clearly.mr. green speaks very loudly sothatallthepeoplecan hear him clearly.in order that意为“为了”， 相当于so 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。weshallletyouknowthe details soon in order that you can/maymakea arrangements.6. 结果状语从句引导词用法示例sothat意为“如此 以至于”。so+ 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this year it has rained so heavily in south china that lots of problems are caused.the ice on the lake was sothin that people couldn t skate on it.定搭配。so+ many 或 few+ 复 数可 数名 词+that; so+ much 或 little+ 不可数名词+that.too often, we spend so much time thinking about the future that we fail to enjoy the present.there are so fewnotebooks that i can t give you any.such.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是形容词，修饰名词或名词词 组。有时可与 sothat 句型转换。its such a wonderful song that we all like it.simon is such dishonest person that no one believes him.theboyisso youngthathe can t go to school.= he is such a young boythathecan tgoto school.7. 让步状语从句引导词用法示例though意为“虽然。”不能和 but 连用。但是可以同yet(still) 连用，so it has livedup to now though it isnt strong at all.构成thoughyet(still). though 较普遍，常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eventhough=even if(nomatterif;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)。though they are twin brothers, they don t look like each other.even if/ even though we could afford it, we would afford it, we wouldn t go abroad for our vacation.although意为“虽然。”不能和 but 连用。但是可以同 yet(still) 连用， 构 成 although yet(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。although he died several years ago, i can still remember the days we spent together and what he has taught me about love.although we had little foodwith us, we decided to spend the night in the car.8. 比较状语从句引导词用法示例asas.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,aquarter 等，则须置于第一个 as 之前。she is very good at painting. she can paint as well as here teacher.i ran out as quickly as possible.not as / soas意为“和 不一样，不如”。也表示同级比较。she is not so (as ) outgoing as her sister.this dictionaryis notas/souseful as you think.9. 方式状语从句引导词用法示例as/(just)as.so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whenin rome,doas the romans do.aswateristo fish,soair is to man.如，就像”， 多用于正式文体。as if/ as though意为“就像，好像。” 两者ifwouldneverforget的意义和用法相同，引heresmile,or the way出的状语从句谓语多用her eyes shone as if we虚拟语气，表示与事实were the same age.相反，有时也用陈述语itlooksasifthe气，表示所说情况是事weathermaypickup实 或 实现 的 可能 性较very soon.大。常译作“仿佛似的，好像似的”。练习一一. 单项填空1. hes old, he can still carry this heavy bag.a. thoughb. sincec. ford. so2. -do you know if he to play basketball with us?-i think he will come if he free tomorrow.a. comes;
