I like tea while helike coffee.Please dont talk so loud while others are working.总结：while引导的从句谓语动词必须是_, 常用_时。作为并列连词，表示_，翻译成_；语气比but _。把while的含义写在后面括号内：While we didnt agree, we continue to be good friends. ( )While they are my neighbors, I dont know them well. ( )While there is life, there is hope. ( )Strike the iron while it is hot. ( ) 总结：while 除了引导时间状语从句外，还可以引导_。3. as引导时间状语从句：As time goes on, its getting warmer and warmer. He hurried home, looking behind as he went. 从属连词as 可表示从句和主句的两个动作交替进行或同时发生，可译为_或者_。温馨提示：当主句表示的是短暂的动作，而从句用延续性动词的进行时态表示一段时间内正在进行的动作时，when ,while ,as 可互换使用。When /While/As I was walking down the street, I came across an old friend of mine.题组训练用while，when， as 填空： _ I was walking down the street, I noticed a police car in front of the store._ John arrived, I was cooking lunch._ he grew older, he lost interest in everything except gardening.How can he get good grades _ he wont study?I was wandering through the street_ I caught sight of a tailors shop._ the grandparents love the children, they are strict with them. as soon as, immediately, directly, instantly, the moment, the minute, the instant, no soonerthan,hardly(scarecely,barely)when这些从属连词引导的从句的动作一发生，主句的动作随即发生，常译为_.The moment I heard the voice, I knew father was coming.No sooner had we arrived at the station than the train left.The boy burst into tears immediately he saw his mother. 注意：在no soonerthan ;hardly/scarcely/barelywhen 结构中，主句用_，从句使用_时态。此外，当把no sooner或hardly等提到句首时，应用_语序。I had hardly got home when it began to rain.=Hardly _.I had no sooner come home than it began to rain.=No sooner _.题组训练英译汉：They phoned immediately they reached home._The year my brother joined the army I graduated from the high school._I had waited for 3 hours by the time the train arrived.(注意主句时态： )_Every time I see her, she is always busy._I want to see her the moment she arrives._表示时间的名词或名词短语也可以引起时间状语从句，如：_. till until 和not untilHe remained there until she arrived.You may stay here until the rain stops.He wont go to bed until she returns.Until you told me I have no idea of it.It was not until you told me that I had any idea of it.Not until you told me did I have any idea of it. 观察以上各句，找出用法。肯定句：主句谓语动词必须是_,意为某动作一直延续到某时间点才停止。否定句：主句谓语动词必须是_,意为某动作直到某时间才开始。_可以用于句首，而_不可以。在强调句型中not until 两词在一起不分开；句首时，_要倒装。题组训练句型转换I didnt leave until she came back._she came back _leave._not until she came back_ I _. before ,after和since1.before, 在之前：翻译下面的句子：Look before you leap. _All things are difficult before they are easy. _把下列各句中的before的含义写在后面：We had sailed four days and four nights before we saw land. （）We hadnt run a mile before he felt tired. （）Please write it down before you forget it. （）Before I could get in a word, he had measured me （）before 构成的固定句型，看例句总结：It will be a year before you leave school.It was a long time before I got to sleep again.

It was years since I had seen her._. 把以上句子翻译成汉语。_在“It is + 一段时间+ since 从句”句型中，时间的计算一律从从句的动作完成或状态结束时算起。3. after 在之后I will tell them after you leave (you have leave ).I told them after you left/ had left .你能发现after之后的时态吗？_三地点状语和原因状语从句1地点状语引导词为_和_.请填写：You are free to go _ you like.Go back _ you come from.Make a mark _ you have any questions.翻译下列句子：Where there is a will, there is a way. _ Wherever there is smoke, there is a fire. _以上两句where从句表示抽象含义，从句必须放在主句之前。注意区分where 引导的状语从句和定语从句题组训练,判断下列各句中包括什么从句：Go back to the place where you come from.

( )总结：你是根据什么作出判断的？_2.原因状语从句引导词：because, as, since, now that, 每个连词的含义不尽相同，观察例句总结用法：-Why were you absent from the meeting?-Because I was ill.As it is raining, we shall not go to the park.Now that/Since everybody is here, lets begin our class.Since you are busy, you dont have to go.总结：because表示_, 用来回答_提出的问题； as 和since表示_, as 可以翻译成_,since 翻译成_;as 的位置可以在主句前或者后，而since ,now that 只能在主句_.此外，for,并列连词，也可表示原因，起补充说明的作用。It must have rained last night, for it is wet all over.四.目的状语从句和结果状语从句目的状语从句的引导词有从属连词_I will speak slowly _ you can understand me._ we might see the sunrise, we started for the peak early.在口语中，so that 引导从句时，_可以省略。We will seat near the front so (that) we can hear more clearly.The boy hid himself behind the tree _ his father ( should ) see him.for fear that, in case, lest 引导目的状语从句，谓语动词可以使用should +动词原形。引导结果状语从句的引导词有_,观察例句，概括结构：Mike is such an honest worker that we all believe him.Mike is so honest a worker that we all believe him.It is such fine weather that we all want to go to the park.He earned so little money that he couldnt support his family._ _._ _当so或such置于句首时，主要倒装语序。So clever a student _that he was able to work out the difficult problem.题组训练：用so 或such填空It is surprising that _ little worms eat _ many grains.He is _smart a boy that I like him very much.Can you believe that in _ a rich country there should be _ many poor people?思考：suchas结构中，as 引导的是什么从句？观察下面的句子并作出回答：I never heard such stories as he tells.
