從屬連詞 狀語從句一、重點(diǎn)知識(shí)歸納及講解（一）從屬連詞 從屬連詞是引導(dǎo)狀語從句，賓語從句及其他從句的連詞。 1引導(dǎo)狀語從句的從屬連詞有： 1）when, while, before, after, as soon as, until, since等，引導(dǎo)時(shí)間狀語從句。 2）because, as, since等引導(dǎo)原因狀語從句。 3）if, as long as等引導(dǎo)條件狀語從句。 4）though, although引導(dǎo)讓步狀語從句。 5）sothat, suchthat等引導(dǎo)結(jié)果狀語從句。 6）so that引導(dǎo)目的狀語從句。 7）asas；than等引導(dǎo)比較狀語從句。 2常用從屬連詞的辨析 1）when, as, while when, as, while都表示“當(dāng)?shù)臅r(shí)候”，但when引導(dǎo)的時(shí)間狀語從句的動(dòng)作和主句的動(dòng)作可以是同時(shí)發(fā)生，也可以先后發(fā)生，when既可指時(shí)間點(diǎn)，也可指一段時(shí)間，所以既可引導(dǎo)一短暫動(dòng)作動(dòng)詞，也可引導(dǎo)持續(xù)性動(dòng)作的動(dòng)詞。 用as作從屬連詞引導(dǎo)時(shí)間狀語時(shí)強(qiáng)調(diào)主句和從句的動(dòng)作并行發(fā)生，不指先后，尤指短動(dòng)作或事件同時(shí)發(fā)生。如：As I looked, someone came near.（正當(dāng)我看的時(shí)候，有個(gè)人走上前來。）as還可說咱兩種正發(fā)展或變化的情況，意為“隨著”。如：As spring warms the earth, all flowers begin to bloom.（隨著春回大地，百花開始綻放。）表示主從句動(dòng)作同時(shí)，as意為“一邊一邊”。如：He hurried home, looking behind as he went.（他匆匆忙忙跑回家，一邊走一邊回頭望。） while只指一段時(shí)間，從句中的謂語動(dòng)詞不能用終止性動(dòng)詞，強(qiáng)調(diào)某一段時(shí)間內(nèi)主從句動(dòng)作同時(shí)發(fā)生，常對(duì)同類的動(dòng)作進(jìn)行對(duì)比。如：While we were waiting for a bus, it was raining hearily.（我們?cè)诘溶嚂r(shí)，天正下著大雨。） 2）till和until till和until都表示“直到為止”。主句用延續(xù)性動(dòng)詞，主句和從句都用肯定式：意為“直到才”。主句用終止性動(dòng)詞，從句用肯定式，主句用否定式。until較till正式，until引導(dǎo)的時(shí)間從句可以放在句首。 例如： She wont go away till you promise to help her. 直到你允諾要幫助她，她才走開。 Until you told me, I had heard of nothing what happened. 直到你告訴我，我才知道發(fā)生了什么事。 3）since since引導(dǎo)的時(shí)間狀語從句常用一般過去時(shí)，其主句一般使用現(xiàn)在完成時(shí)。 例如：Jim has been in the factory for two years since he left school. 從吉姆畢業(yè)起，他在這家工廠工作兩年了。 （二）狀語從句 修飾主句中的謂語動(dòng)詞，形容詞或副詞等的從句叫狀語從句。 例如： He didnt go to school yesterday because he was ill.（修飾動(dòng)詞go） 昨天他沒去上學(xué)，因?yàn)樗×恕?We must study so well as our teacher hoped.（修飾副詞well） 我們應(yīng)該學(xué)得你我們老師希望的那么好。 Lucy is younger than Jim(is)。（修飾形容詞younger） 露茜比吉姆年輕。 狀語從句的語序應(yīng)是主語+謂語+其他成分，即陳述句的語序。 狀語從句的位置，可以放在主句前面或后面，但是若放在主句前面，要用逗號(hào)與主句分開；主句若是疑問句，那么時(shí)間狀語從句只能放在主句的前面。 1）時(shí)間狀語從句 時(shí)間狀語從句由when, while, after, before, since, as soon as, till, until等連詞引導(dǎo)。 例如： I went to bed after the TV play was ever. 電視劇完了以后我上床睡覺。 Could you look after her while were away? 我們不在時(shí)你能照顧她嗎？ She has taught in this school since she came to this city in 1989. 自從一九八九年她來到這座城市以來一直在這所學(xué)校教書。 Wait until I come back. 請(qǐng)你等到我回來。 注意： 如主句是一般將來時(shí)，則表示將來的時(shí)間狀語只用一般現(xiàn)在時(shí)。 例如： Ill write to you as soon as I get to Beijing. 我一到北京就將寫信給你。 It will get warmer and warmer when spring comes. 春天來臨時(shí)，天氣將變得越來越暖和。 2）原因狀語從句 原因狀語從句由because, as, since等連詞引導(dǎo)。 例如： He sold the car because it was too small. 他賣掉那輛小汽車，因?yàn)樗×恕?Since you wont help me, I must do the job myself. 你既然不幫我忙，我必須自己做這項(xiàng)工作。 As my mother is away at this moment, I have to look after my younger sister. 由于我的媽媽現(xiàn)在不在，我不得不照顧我的妹妹。 注意： a）because, as, since, for的用法辨析 because, as, since, for都是表示各種理由的連詞，但because多表示所敘述的理由是本句的重點(diǎn)，故because所引導(dǎo)的從句常放在句末。 例如： Why was he absent? Because he was badly ill. 他為什么缺度？因?yàn)樗〉煤苤亍?as, since用于表示理由是已知，而理由以外才是敘述的重點(diǎn)，兩者皆多用于句首，但要注意since重形式，as多表示理由以外的才是重點(diǎn)。 例如： As it is raining, lets stay as home. 因?yàn)橄掠辏覀兙土粼诩依锇伞?Since you have no license, you are not allowed to drive. 因?yàn)槟銢]有駕駛執(zhí)照，所以你不可以開車。 for不用于句首，而用于主句之后，補(bǔ)充說明理由；主句表推測(cè)時(shí)，用for說明原因。 例如： Ill follow his advice, for he is a doctor. 我會(huì)聽從他的勸告，因?yàn)樗轻t(yī)生。 b）because of也是表示原因狀語，但后面只能跟短語。 例如： I stayed at home because of the bad weather. 因?yàn)樘鞖獠缓梦伊粼诩依铩?3）比較狀語從句 比較狀語從句由than或as來引導(dǎo)。 例如： I feel better now than (I was) before. 我現(xiàn)在覺得比以前好了。 He writes as well as you (do). 他寫得和你一樣好。 This problem is more difficult than that one (is). 這道題比那道題難。 4）條件狀語從句 條件狀語從句由if, unless（= if not）算連詞引導(dǎo)。條件從句中的動(dòng)詞多用一般現(xiàn)在時(shí)表示將來。 例如： I shall go if he asks me. 如果他請(qǐng)我，我就去。 I shant go unless he asks me. 除非他請(qǐng)我，否則我是不去的。 I shall go, whether he asks me or not. 不管他請(qǐng)不請(qǐng)我，我都要去。 Come with me if you have time. 如果你有時(shí)間請(qǐng)跟我來。 I want to watch a basketball match if Im well tonight. 如果今晚我好了的話，我要看一場(chǎng)籃球賽。 由and連接的簡(jiǎn)單句，可以用條件狀語從句來改寫。 例如： Run faster and youll catch up with him. 跑快點(diǎn)兒你就會(huì)趕上他。 =If you run faster, youll catch up with him. 如果你跑得快點(diǎn)，你就會(huì)趕上他。 5）結(jié)果狀語從句 結(jié)果狀語從句由so that, so that引導(dǎo)。 例如： He has lost his bike so that he cant come to school on time.（結(jié)果狀語） 他去了自行車，所以不能準(zhǔn)時(shí)到校。 Your shirt were so dirty that you must wash it.（結(jié)果狀語） 你的襯衣這么臟，你應(yīng)該把它洗洗。 注意： 由sothat引導(dǎo)的狀語從句若是表示否定意思，可以用tooto（太而不能）來替換。 例如： She was so angry that she could not say a word. =She was too angry to say a word. 她氣得說不出話來。 6）讓步狀語從句 讓步狀語從句一般用though（雖然）、although（雖然）、even though（即使）引導(dǎo)。 例如： Though/Although he tried hard, he was not successful. 他雖然努力嘗試，但沒有成功。 He went on working though it was very late. 雖然很晚了，他還在繼續(xù)工作。 注意： 1漢語中的“雖然但是”在英語中用連詞though就可以了，或單獨(dú)使用but連接兩個(gè)并列句也可以，但不能在一個(gè)句子中同時(shí)用這兩個(gè)連詞（主句前不用連詞）。 例如： “雖然我很喜歡照顧我姐姐的嬰兒，但她不讓我干”。這個(gè)句子我們可以用下面兩種方法來表達(dá)。 Though I like looking after my sisters baby, she doesnt let me do it. I like looking after my sisters baby, but she doesnt let me do it. =though可以與yet連用，這里yet雖然意思與but相同，但yet不是連詞，而是副詞。 例如：Though it was cold, yet he went out without a coat. 雖然很冷，但他沒穿外衣就出去了。 二、隨堂監(jiān)測(cè)A組 I. 用when, before, after, until, as soon as, if, as, because, though, than, since, sothat填空: 1.
