状语从句学员姓名： 年级：九年级 辅导科目：英 语 学科教师： 授课日期授课时段08：00-10:00授课主题状语从句教学内容课前回顾1. 单词默写2. 作业讲解知识梳理知识点1：状语从句状语从句种类1.时间状语从句；(adverbial clause of time) 2.原因状语从句；(adverbial clause of cause) 3.条件状语从句；(adverbial clause of condition) 4.让步状语从句；(adverbial clause of concession) 5.比较状语从句；(adverbial clause of comparison) 6.目的状语从句；(adverbial clause of purpose) 7.结果状语从句。(adverbial clause of result) 状语从句的时态特点 一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。（主将从现）例如： I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话。（这是由as soon as引导的时间状语从句，从句中的谓语动词arrive是一般现在时，表示一般将来时，绝不可用will arrive） 状语从句用法分析（一） 时间状语从句：1） 连接词when、while、as引导的时间状语从句。while: 可表示对比（从句只用连续性动词）2） 由till或until引导的时间状语从句，一般情况下两者可以互换。如果主句中的谓语动词是瞬时动词时，必须用否定形式；“直到.才”如果主句中的谓语动词是延续性动词时，用肯定形式， “直到”I didnt go to bed until（till） my father came back.直到我父亲回来我才上床睡觉。 I worked until he came back.我工作到他回来为止。3） 由since引导的时间状语从句。 “自从”since引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。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 /has been一段时间时间since从句的句型中，主句多用一般现在时，从句为过去时。I have been in Beijing since you left. 自从你离开以来，我一直在北京了。4） 由as soon as引导的时间状语从句。表“一就”。 As soon as I reach Canada, I will ring you up. 我一到加拿大，就给你来电话。5） 由by the time引导的时间状语从句。注意时态的变化：在一般情况下，如果从句的谓语动词用一般过去时，主句的谓语动词用过去完成时；例如：By the time you came back, I had finished this book.到你回来时，我已经写完这本书了。6） before, after引导的时间状语从句主、从句的动作发生有先后关系，动作在前的，要用过去完成时，动作在后的要用一般过去时。如： After he had finished his homework, he went to bed. 随堂小练：1. The crew members didnt leave _ all the passengers got off the plane. A) whenB) whileC) untilD) unless2. _ I saw the flag rising at Beijing Olympic Games, I really felt proud of China. A) BeforeB) UntilC) WhenD) If 3. My brother was writing an e-mail _ I was watching TV this last night. A. after B. until C. while D. as soon as4. The firemen stopped working when all the workers were saved.(保持句意基本不变) The firemen _ stop working _ all the workers were saved.5. Mary finished her work. Then she went home. (合并为一句)Mary_ go home_ she finished her work. CCC didnt until; didnt until;（二）原因状语从句由连词because, since, as引导, 也可由for, now that 等词引导I didnt go to school yesterday because I was ill. 我昨天没去上学，因为我生病了。Since everybody is here, lets begin our meeting. 既然大家都来了, 让我们开始开会吧.As you are in poor health, you should not stay up late. 既然你身体不好, 你就不该熬夜. I asked her to stay to tea, for I had something to tell her. 我请她留下来喝茶,因为我有事要告诉她.Now that sinner is ready, go and wash your hands. 既然饭已经准备好了， 去洗手吧。难点：because , since , as , for,辨析because, as, for, since这几个词都是表示“原因”的连词，语气由强至弱依次为：because since as for。 其because, since, as均为从属连词，引导原因状语从句；而for 是并列连词，引导并列句。随堂小练：1. Mary was late for the party _ something went wrong with her car.A) so thatB) untilC) becauseD) though2. _ youre interested in Chinese history, lets go to the Shanghai Museum. A) SinceB) BecauseC) AlthoughD) For3._you have made up your mind to lose weight, youd better eat less in the evening.A) Since B) Although C) Unless D) UntilCAA（三）目的状语从句由so that, in order that. 表示“为了，以便”连接的目的状语从句。如：Cherry was walking quickly so that (in order that) she could arrive at the cinema in time.John sent the mail by air in order that (so that) it might arrive a little earlier.注意：1）通常情况下，so that 等于in order that.2）从句中往往出现情态动词：cancouldmaymight3）当主从句的主语一致时，可转换为相应动词不定式结构：so as toin order toIn order to 后跟动词原形，in order that 后跟从句。随堂小练：1. She stood up _ she could see the words on the blackboard clearly. A) so thatB) such asC) asD) in order to2.This morning I got up earlybe late for the English exam.A) in order thatB) in order to notC) so as toD) so as not toAD（四）结果状语从句由sothat连接结果状语从句so.that=.enough to do sothat(not)=tooto do =not +(反义词)+ enough to do同义句转换The little boy is so short that he cant reach the map on the wall.The little boy is too short to reach the map on the wall.The boy is not tall enough to reach the map on the wall.注意：tooto 和enough to后跟动词原形，sothat后跟从句。 such aan +形+单名=so+形+aan+单名 “如此以至于”随堂小练：1.The boy is so clever that he can work out the problem himself. (保持原句意思)The boy is clever _ _ work out the problem himself. （崇明县）2. The little girl was frightened in the darkness. She began to cry for help. (合并为一句) The little girl was _ frightened _ she began to cry for help. （松江区）3. Jenny eats less meat in order to lose some weight.（保持原句意思不变） Jenny eats less meat _ _she can lose some weight.4. The ice cream will melt, so youd better put it in the bridge at once. (保持原句意思不变) The ice cream will melt _you_ put it in the bridge at once. 1.enough to 2.so that 3.so that 4. If dont（五）条件状语从句： 表示状语从句由连词if, unless (=if not) 引导。 If it doesnt rain tomorrow, we will go hiking.如果明天不下雨, 我们就去远足. I will go to the party unless he goes there too.我不会去参加聚会的, 除非他也去.(如果他不去,我也不去.) You will be late unless you leave immediately.如果你不马上走,你将会迟到的.(=If you dont leave immediately, you will be late.)难点：用条件状语从句时要注意时态的正确使用,当主句是将来时的时候,从句要用一般现在时.He will not leave if it isnt fine tomorrow.一般将来时， 一般现在时随堂小练：1. The British singer Adele says she wont go on a diet _ its for health reasons. A) since B) until C) unless D) because2. _ all of us can learn to love, everything around us will be a wonder.A) BecauseB) IfC) BeforeD) Although3. Mr. Li wont allow us to play football _ weve finished our homework. A) ifB) whenC) becauseD) unless4. If you dont improve your handwriting, youll lose marks in the exam. (保持原句意思)_ you _ your handwriting, youll lose marks in the exam. （金山区）5. Be quick, or you will miss the school bus. (保持句意基本不变) You will miss the school bus _ you _ quick. CBD Unless improve; unless be（六）让步状语从句 表示让步的状语从句由连词 though, although，even if引导.though, although当“虽然”讲, 都不能和but连用. Although, (though)but的格式是不对的.但是他们都可以同 yet (still) 连用. 所以thought (although)yet(still)的格式是正确的。比较：l). W: Although he is rich but he is not happy. R : Although he is rich, yet he is not happy. 虽然他很富有, 然而他并不快乐.2). R: Although we have grown up, our parents treat us as children. R : Although we have grown up, our parents still treat us as children. 尽管我们已经长大了,可是我们的父母仍把我们看作小孩。 even if, even though“即使”重难点：主将从现主将从现是指在在复合句中，由when, as soon as, after, before, until等引导的时间状语从句和由if, unless引导的条件状语从句，都符合“主将从现”的原则，即主句是一般将来时（或用一般现在时表示一般将来时的意义），从句要用一般现在时。通常分为三类情况：(1) 主：（一般将来时）；从：（一般现在时）. I will call you as soon as I arrive in New York. (2) 主：（祈使句）；从：（一般现在时）. Dont laugh at me when I make a mistake. (3) 主：（含有情态动词的一般现在时）；从：（一般现在时）.
