12、间状语从句：这里主要讲时间状语从句和条件状语从句这一块往往和从属连词（专题十四）一块考时间，条件状语如果主句用了一般将来时从句将用一般现在时表将来含义。1.时间状语从句时间状语由when，while，as,as soon as,since,until/till,not.until/till,before,after等引导。(1)when引导的从句：表示主句的动作和从句的动作同时发生，或从句的动作发生在主句动作之前。eg：I was going out when a visitor came.(动词动作同时发生。)。(2)while 引导的从句：表示“当过程中”，强调某一段时间内主句和从句中谓语

13、动词所表示的动作在同一时期发生。由于while从句表示一个持续的行为，所以从句中要用持续性动词，并且持续性动词常用进行时态。eg：Keep an eye on my little sister while I am away.(3)as引导的时间状语从句：表示“当的时候；一边一边；随着”，其从句的主语与主句的主语往往是同一人或物。eg：She sang as she worked.她一边工作一边唱歌。=She was singing as she was working.I saw him as he was getting off the bus.正当他下公共汽车时,我看见了他。(4)bef

14、ore引导的从句：一般表示主句的动作发生在从句动作之前。eg：I didnt know any English before I came here.我到这儿来之前，一点英语都不懂。eg：I had written my report before my father came back.(5)after引导的从句：表示主句的动作发生在从句动作之后。eg：After he locked the door,he left.他锁上门后，就走了。他做完工作后，和朋友下了一盘棋。小试牛刀：I will go out to play basketball with you.I finish my hom

15、ework.(after)6since引导的从句：表示“自从以来”，从句中的动词一般表示动作的起点，用过去时。since表示“自以来”，主句主句用一般现在时或现在完成时，从句用一般用一般现在时或现在完成时，从句用一般过去式。过去式。eg：Since he met this good friend,he has made great progress in his studies.Mr green has taught in that school since he(came)to China three years ago.7Until/till 引导的从句：表示一个动作持续到某一时刻。（1)

16、Until/till表示“直到”，如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。（2）notUntil/till表示“直到才”，主句用否定式，从句用肯定。如果主句中的谓语动词是瞬间动词时，必须用否定形式。例如：They worked until it was late.他们一直工作到天黑。She didnt go to bed until she finished her homework.她写完作业才睡觉。小试牛刀：All the people left.He waited.(until)_He went to bed.his father came home

17、._8as soon as 引导的从句表示“一就”，强调动作紧密相连。例如：As soon as she came to the classroom,she began to read English.她一到教室，就开始读英语。小试牛刀：We start to sing.Its 12 oclock.(as soon as)_分析试题特点及做题思路：分析试题特点及做题思路：题形题形（1）选择题：）选择题：考连词考连词-做题思路：做题思路：考时态考时态-做题思路：做题思路：认字认字-判断关系判断关系-选择正确的连词选择正确的连词认字认字-判断语境提供的时态特点判断语境提供的时态特点-选择正选择正确

19、told that we should follow the main road _ we reached the central railway station.A.whenever B.until C.while D.wherever 2.条件状语从句条件状语从句引导词：引导词：If/ifnot,unless,aslongas,without条件状语和时间状语一样如果主句用了一条件状语和时间状语一样如果主句用了一般将来时，从句就用一般现在时表将含义般将来时，从句就用一般现在时表将含义。位置：从句可放在主句之前或之后，但是放在主句之前须有从句可放在主句之前或之后，但是放在主句之前须有逗号隔开

20、逗号隔开eg:如果我有足够的钱，我就去环游世界（1）If 引导条件状语从句 定义：定义：if“如果如果,假如假如”它引导的句子表示某事发生所需的它引导的句子表示某事发生所需的条件，即条件，即“在在条件下，某事才能发生条件下，某事才能发生”，在句子中充当状语，在句子中充当状语，因此称之为条件状语从句。（因此称之为条件状语从句。（If引导的条件状语从句表示假引导的条件状语从句表示假如有从句的动作发生，就会有主句动作的发生如有从句的动作发生，就会有主句动作的发生）If I have enough money,I will travel around the world=I will travel a

21、round the world if I have enough money用法：1.如果主句是一般将来时，从句则用一般现在时如果主句是一般将来时，从句则用一般现在时(主将从现）。主将从现）。If it rains（从句），I will stay at home.Ill go with you if you dont want to go alone（从句）.2.如果主句含有如果主句含有must,may,can 等情态动词，从句也要用等情态动词，从句也要用一般现在时。一般现在时。If you drive too fast,you may have an accident.You must st

22、op if the traffic is red.3.如果主句是祈使句，从句同样要用一般现在时。如果主句是祈使句，从句同样要用一般现在时。Dont go and play football if you dont finish your homework.Please call me if he comes next Sunday 注意注意if 引导的条件状语从句和宾语从句的区别引导的条件状语从句和宾语从句的区别 1.Youll be late _ you dont get up early tomorrow morning.A.if B.when C.before D.until 2.If

24、主将从现）如果如果是否是否2)unless在意义上相当于在意义上相当于ifnot。You will fail unless you study hard.You will fail if you dont study hard3)“祈使句祈使句+and(or)+陈述句陈述句”在意思上相在意思上相当于一个带有条件状语从句的复合句。其当于一个带有条件状语从句的复合句。其中，中，and表示句意顺承；表示句意顺承；or表示转折，意为表示转折，意为“否则否则”。例如：例如：Hurry up,or youll be late.=If you dont hurry up,youll be late.Stud
