初中英语状语从句精讲

会计学1初中英语状语从句精讲考点揭密在复合句中修饰主句中的动词、形容词或副词或句子，起状语作用的从句。由从属连词引导，从属连词在从句中不充当句子成分。状语从句可置主语之前，也可置主语之后。前置时，从句后用逗号与主句分开；后置时，与主句之间无标点符号。

状语从句可分为时间、原因、目的、结果、条件、比较、地点、让步、方式等九类。e.g.Ifyougototheparty,youwillhaveagoodtime.e.g.YouwillhaveagoodtimeIfyougototheparty.

IgettoBeijing.e.g.Iwilltellhimwhenhecomesback.

注意e.g.Iwon’tgotobeduntilIfinishmyhomework.第4页/共37页(3)not...until的同义句替换。

e.g.

Iwaitedtill/untilhearrived.(wait是一个延续性动词）e.g.Ididn’tleaveuntil/till/beforeshecameback.（leave是个短暂性动词）第5页/共37页

rightnow.除非你现在出发否则的话年上学就会迟到的。e.g.Youwillnotsucceedunlessyouworkhard.

第8页/共37页小结:“祈使句+or+一般将来时的陈述句”结构中，Or表示转折，译作“否则，不然的话”相当于一个否定的条件状语从句。相当于Ifyoudon’t(can’t)…,youwill…例句.Studyharder,oryouwillfailtheexam.=Ifyoudon’tstudyharder,youwillfailtheexam.=Unlessyoustudyharder,youwillfailtheexam.例句.Hurryup,oryouwillbelate.=Ifyoudon’thurryup,youwillbelate.=Unlessyouhurryup,youwillbelate.第9页/共37页

Whyareyoustandinghere?---BecauseI’mwaitingformyuncle.①because从句所表示的是对方不知道的直接的原因，因此在回答以why引导的特殊疑问句时只可用because,它引导的从句可以位于主句前或主句后.而as,since引导的从句却不可；例句:LiHongdidn'tgotoschoolyesterday,becausehewasill.第13页/共37页②as从句所表示比较明显的原因和理由(由于,既然)这种原因一般是大家知道的,一般从句说明原因，主句说明结果。其从句位于主句之前,

③since用来表示比较勉强的理由和原或原由已为人们所知。e.g.Asthewaterwasnotdeep,wewereabletocrosstheriver.(从句说明原因，主句说明结果)e.g.ASIknewhewasill,Ididn'tcallhim.e.g.Sinceeverybodyishere,let’sbiginthemeeting

（“大家都在这里”的原由已为人们所知）e.g.Sinceyoucan’tanswerthequestion,（原由已为人们所知）I’llasksomeoneelse.第14页/共37页for往往用于附加理由证明。所说的理由是一种补充说明。分句前常有逗号，其引导的分句不可放于句首。例句：It’sspringnow,fortheflowersareout.Practice:Whyhasn’tMr.Licometoworktoday.----____hehasgonetoBeijingtohaveameeting.
