初中英语状语从句讲解、练习与答案4

1、状语从句状语从句 用来修饰主句中的动词，副词和形容词的从句叫状语从句；依据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句，缘由状语从句，结果状语从句，比较状语从句，目的状语从句，让 步状语从句；1. 时间状语从句1 时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导；例如：it was raining hard （ rain hard下大雨）when got to school yesterday. while he was doing his homework, the tel

2、ephone rang.as he walked along （沿着走）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 在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态；例如：i ll ring you up as soon as i get to new york. i will tell him everything when h

3、e comes back.he won t believe it until he sees it with his own eyes.3 在带有 till 或 until 引导的时间状语从句的主从复合句里，假如主句用确定式，其含义是“始终到时”，谓语动词只能用连续性动词；假如主句用否定式，其含义是“直到才” , 在“动词可用瞬时动词；例如：the young man read till the light went out（熄灭） . let s wait until the rain stops.we won t start until bob comes.dongtet off （从下来

4、）until the bus stops.以前不” , 谓语【 till 是指直到某一特定大事发生的时候，而在那个时刻之后，该事情或状况仍将连续；until是指直到某一特定大事发生的时候， 而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止（不怎么可能连续） ；固定组合里from morning tillnight ，till/until是不能替换的， 】2. 条件状语从句1 条件状语从句通常由if, unless 引导；例如：what shall we do if it snows tomorrow. don t leave the building unless i tell

5、you to.2 在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态；例如： i ll helypou with your english if am free tomorrow.he won t be late unless he is ill.3 “祈使句+ and or+陈述句 ” 在意思上相当于一个带有条件状语从句的复合句；例如：hurry up, or you ll be=ilfayteo.u don t hurry up, you ll be late. study hard and you will pass the exam. =if you study hard,

6、you will pass the exam.3. 缘由状语从句1 缘由状语从句通常由because, since, as引导；例如： he didn t come to school because he was ill.as it is raining, we shall not（不得；不应当）go the zoo.1since you can t answer the question, i ll ask someone else. 2because 表示直接缘由， 语气最强； because 引导的缘由状语从句多放在主句之后；回答由 why 提出的问题，只能用 because；as 和

7、 since 语气较弱，一般用来表示明显的缘由；由as和 since 引导的缘由状语从居多放在句首；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.3because 和 so 不能 同用在一个句子里；4. 结果状语从句1 结果状语从句由sothat, suchthat, so 引tha导t ；例如： he is so poor that he can t buy a

8、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 sothat语 such.that 可以互换；例如：在由 so.that 引导的结果状语从句中，so 是副词， 与形容词连用； 其结构是 :“.so + 形容词（副词） + that+从句 ”；例如：he was so glad that he couldn t say a word. the hall is so big that it c

9、an hold 2,000 people.mother lives so far away that we hardly ever （几乎不，从来不）see her.在由 suchthat 引导的结果状语从句中，such 是形容词，它修饰的可以是单数或复数可数名词，也可以是不行数名词；名词前面可以带形容词，也可不带；假如是单数可数名词，前面需加不定冠词a 或 an；例如： it was such a hot day that nobody wanted to do anything.he had such long arms that he could almost touch the cei

10、ling. （天花板）he made such rapid progress that he did very well in the mid-term.有时上述两种结构是可以互换的；例如：it was such a wonderful film that all of us wanted to see it again.=the film was so wonderful that all of us wanted to see it again. it is such an important match that nobody wants to miss it.=the match is

11、 so important that nobody wants to miss it.3 假如名词前由many, much, little, few等词修饰时，只能用so, 不用 such；例如： soon there were so many deer that they ate up all the wild roses.he has so little time that he can5. 比较状语从句go to the cinemta （去看电影）with you.比较状语从句通常由asas, 比较级+ than等连词引导；例如：tom runs faster than john do

12、es. this classroom is as big as that one.6. 目的状语从句1 目的状语从句通常由so that, in order that （为了，以便）引导；例如：2we started early so that we could catch the first train.he studies hard so that he could work better in the future. we used the computer in order that we might save time.2so that 既可引导目的状语从句，又可引导结果状语从句；区

13、分这两种从句的方法有两个：1 目的状语从句里往往带有情态动词can, could, may, might 等；2从意思上看， 目的状语从句往往表示的目的很明确；例如：speak clearly so that they may understand you. 目的状语从句 jack is badly ill so that he has to rest.结果状语从句 7. 让步状语从句1 让步状语从句通常由although, though 等连词引导；例如：though he is young, he knows a lot. although i am tired, i must go on

14、 working.2althoughthough 不能用在同一个句子中；例如：我们不能说： though it was raining hard, but he still went out.应当说： though it was raining hard, he still went out.或 it was raining hard, but he still went out.8. 地点状语从句地点状语从句经常由where 来引导；例如：go where you like.where there is a will, there is a way.总结： 状语从句分类及常用连词：类别连词时
