狀 語 從 句 詳 解,祿勸一中 董加維 2009年4月8日,狀語從句,用作狀語的從句叫做狀語從句。引導(dǎo)狀語從句的關(guān)聯(lián)詞是一些從屬連詞。 例： When you cross the road, you must be careful. 當(dāng)你過馬路時(shí)要小心。（when是從屬連詞） I was late because I missed the bus. 我遲到了，因?yàn)槲艺`了公共汽車。（關(guān)聯(lián)詞是從屬連詞because）. If she asks me, Ill tell her. 她如果問我，我就告訴她。（關(guān)聯(lián)詞是從屬連詞if） You look as if you need a rest. 你像是需要休息似的。（關(guān)聯(lián)詞是從屬連詞as if）.,從上面的例子可以看出，狀語從句的位置比較靈活，有時(shí)可以放于句首，有時(shí)可以置于句末。狀語從句位于句首時(shí)，其后常用逗號與后面的句子隔開。 狀語從句可以根據(jù)其用途分為時(shí)間狀語從句、地點(diǎn)狀語從句、原因狀語從句、結(jié)果狀語從句、程度狀語從句、目的狀語從句、條件狀語從句、讓步狀語從句及方式狀語從句，今天我們主要來復(fù)習(xí)時(shí)間狀語從句、原因狀語從句、結(jié)果狀語從句、目的狀語從句、條件狀語從句、讓步狀語從句等。,1. 時(shí)間狀語從句,引導(dǎo)時(shí)間狀語從句的關(guān)聯(lián)詞常有：after, before, when, while, whenever, as soon as, as, since, until等。例： The ball goes up very high after it hits the ground. 這球著地后蹦得很高。 Wait until youre called. 你等著叫你吧！ When he came, I was cooking. 他來時(shí)，我在做飯。 Ill call you as soon as I come back. 我一回來就給你打電話。 Before they came back, we had finished the work. 他們回來前，我們已經(jīng)完成工作了。 We havent seen each other since he left. 從他離開后我們沒見過面。,2. 原因狀語從句,原因狀語從句通常由because, as, since等詞引導(dǎo)。 because語氣較強(qiáng)，用以回答why問句 as語氣較弱，較口語化，所表示的原因較明顯。 since語氣較弱，常表對方已知的事實(shí)，相當(dāng)于漢語的“既然”。,e.g.,I eat potatoes because I like them. 我吃土豆是因?yàn)槲蚁矚g土豆。 As I didnt know the way, I asked a policeman. 我由于不知道路，因而問警察。 Since you wont help me, Ill ask someone else. 你既然不幫我，那我就請別人幫我。,3. 結(jié)果狀語從句,結(jié)果狀語從句常用so that, such that等關(guān)聯(lián)詞引導(dǎo)。 e.g. He is so young that he cant go to work. 他如此小以致于他不能上班。 He got so little pay that his family had to live on welfare money. 他工資很少，他的家人不得不靠救濟(jì)金生活。 Its such a good chance that we mustnt miss it. 機(jī)會這樣好，我們決不能失掉。,4. 目的狀語從句,目的狀語從句常由so that, in order that等詞引導(dǎo)，目的狀語從句常用助動詞may（might）, shall（should）, will（would）, can (could)。目的狀語從句常放于主句之后，例： Speak clearly so that they may understand you. 你要講得清楚，他們才聽得懂。 He spoke slowly in order that everyone should understand. 他講得很慢以便人人能聽懂。,5. 條件狀語從句,條件狀語從句表示條件，關(guān)聯(lián)詞常用if或unless, as (so) long as. If it snows tomorrow, we will build a snowman. 明天如果下雪，我們就堆雪人。 Youll catch a cold unless you put on your coat. 你會感冒的除非你穿上大衣。 He will do anything as long as it is interesting. 只要有趣，他什么都愿意干。,6. 讓步狀語從句,讓步狀語從句，表示“雖然，盡管，即使”等概念，常用的關(guān)聯(lián)詞有：though, although, even though等。 Though he was ill, he was still working. 他雖然有病，但仍然繼續(xù)工作。 Although it is difficult, we shall do it. 此事雖難，但我們還是要做。 Even though you say so, I do not believe it. 即使你這樣說，我也不信。,注：,though和although可以互換，只是although比較正式。 though不可以與連詞but連用，但可以與yet，still連用，例： Though he worked hard, he couldnt pass the exam. 雖然他很努力，但還是沒通過考試。,7. 比較狀語從句,比較狀語從句常用than或asas引導(dǎo)，than表示兩者的比較，asas表示程度相同的比較。例： He is taller than I. 他比我高。 That book is more interesting than this one. 那本書比這本有趣。 He runs as fast as I （do）. 他和我跑得一樣快。 He is older than me.,注：1,比較狀語從句后面的主語在口語中常用賓格。 如果后面的句子主語為主格時(shí)，可以加助動詞、情態(tài)動詞等。 He can jump higher than I can. 他能比我跳得高。 He came later than LiLei did. 他比李磊來得晚。,注：2,because of和because的區(qū)別 because of后加名詞代詞或動名詞，不加句子，而because加句子，例： Because of his illness, he didnt go to work. 因?yàn)樯?，他沒上班。 Because he was ill, he didnt go to work. 在條件和時(shí)間狀語從句中，如果主句用將來時(shí)，從句常用一般現(xiàn)在時(shí)。 If it doesnt rain, well go fishing. 明天不下雨我們就去釣魚。 As soon as he comes back, Ill let him know it. 他一回來，我就讓他知道這事。 if構(gòu)成條件從句時(shí)意為“如果”，可以放句首也可以放主句后；構(gòu)成賓語從句時(shí)意為“是否”，一般放主句后。,例:,I dont know if he will come tomorrow.（賓從） 我不知道他明天是否來。 If he comes, Ill tell you.（Ill tell you if he comes.） 如果他來，我會告訴你。,【模擬試題】（答題時(shí)間：50分鐘）,（ ）1.
