【正文】 狀語從句狀語從句用來修飾主句中的動詞，副詞和形容詞的從句叫狀語從句。根據(jù)其含義狀語從句可分為時間狀語從句，地點狀語從句，條件狀語從句， 原因狀語從句，結(jié)果狀語從句，比較狀語從句，目的狀語從句，讓步狀語從句。1. 時間狀語從句(1)時間狀語從句常用when, as, while, before, after, since, till, until, as soon as等連詞來引導。例如：It was raining hard（rain hard 下大雨） when got to school yesterday.While he was doing his homework, the telephone rang.As he walked along（沿著走） the lake, he sang happily.He had learned a little Chinese before he came to China.After he finished middle school, he went to work in a factory.(2)在時間狀語從句里，通常不用將來時態(tài)，用現(xiàn)在時態(tài)表示將來的動作或狀態(tài)。例如：I’ll ring you up as soon as I get to New York.I will tell him everything when he es back.He won’t believe it until he sees it with his own eyes.(3)在帶有till或until引導的時間狀語從句的主從復合句里，如果主句用肯定式，其含義是“一直到……時”，謂語動詞只能用延續(xù)性動詞。如果主句用否定式，其含義是“直到……才……”, “在……以前不……”, 謂語動詞可用瞬間動詞。例如：The young man read till the light went out（熄滅）.Let’s wait until the rain stops. We won’t start until Bob es. Don’t get off（從下來） until the bus stops.【Till是指直到某一特定事件發(fā)生的時候，而在那個時刻之后，該事情或狀況仍將持續(xù)。 Until是指直到某一特定事件發(fā)生的時候，而講話的人在自己心里認為，在那個時刻之后，該事情或該狀況將中止（不怎么可能持續(xù)）。固定組合里from morning till night，till/until是不能替換的，】2. 條件狀語從句(1)條件狀語從句通常由if, unless引導。例如：What shall we do if it snows tomorrow?Don’t leave the building unless I tell you to.(2)在條件狀語從句里，謂語動詞通常用現(xiàn)在時態(tài)表示將來的動作或狀態(tài)。例如：I’ll help you with your English if am free tomorrow.He won’t be late unless he is ill.(3)“祈使句 + and (or)+ 陳述句” 在意思上相當于一個帶有條件狀語從句的復合句。例如：Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late.Study hard and you will pass the exam. =If you study hard, you will pass the exam.3. 原因狀語從句(1)原因狀語從句通常由because, since, as引導。例如：He didn’t e to school because he was ill.As it is raining, we shall not （不得；不應該）go the zoo.Since you can’t answer the question, I’ll ask someone else.(2)because表示直接原因，語氣最強。Because引導的原因狀語從句多放在主句之后?；卮鹩蓋hy提出的問題，只能用because。As和since語氣較弱，一般用來表示明顯的原因。由as和since引導的原因狀語從居多放在句首。例如：Why aren’t going there?Because I don’t want to.As he has no car, he can’t get there easily.Since we have no money, we can’t buy it.(3)because和so不能同用在一個句子里。4. 結(jié)果狀語從句(1)結(jié)果狀語從句由so…that, such…that, so that引導。例如：He is so poor that he can’t buy a bike for his son.She is such a good teacher that everybody likes her.My pencil fell under the desk, so that I couldn’t see it.(2)so…that語such...that可以互換。例如：在由so...that引導的結(jié)果狀語從句中，so是副詞，與形容詞連用。其結(jié)構(gòu)是: “...so + 形容詞（副詞）+ that + 從句”。例如：He was so glad that he couldn’t say a word.The hall is so big that it can hold 2,000 people.Mother lives so far away that we hardly ever（幾乎不，從來不） see her.在由such…that引導的結(jié)果狀語從句中，such是形容詞，它修飾的可以是單數(shù)或復數(shù)可數(shù)名詞，也可以是不可數(shù)名詞；名詞前面可以帶形容詞，也可不帶。如果是單數(shù)可數(shù)名詞，前面需加不定冠詞a或an。例如：It was such a hot day that nobody wanted to do a
