2.while只表示一段持续的时间，有“在……的同时”的意思，主句的动作在从句动作发生的过程中或主从句两个动作同时发生，从句中的动词必须是延续性动词。Theyweresingingwhileweweredancing.他们在唱歌，我们在跳舞。Whilehismotherwascookinginthekitchen,theboyfellasleepinthechair.

当他妈妈在厨房里做饭的时候，男孩在椅子上睡着了。【注意】(1)由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时；如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导。如：当老师进来时，我们正在说话。Whentheteachercamein,weweretalking.当此句改变主从句的位置时，则为：Whileweweretalking,theteachercamein.【注意】(2)when和while还可作并列连词。when表示“在那时，此时突然”；while表示“然而，却”，表对比或转折关系。并列连词when常用于以下句型中：①...was/weredoing...when...(正在做……突然)②...was/wereabouttodo...when...(刚要做……突然)③...haddone...when...(刚一……就)Iwasabouttoleavewhenthetelephonerang.我正要离开的时候，电话铃响了。Wewereworkinginthelab,whenthelightswentout.我们正在实验室里工作，突然灯灭了。Ihadgonetosleepwhentherewasaknockatthedoor.当有人敲门的时候，我刚要去睡觉。When(Iam)helpingothers,Ifeelhappy.

在帮助他人时,我感到快乐.b.Hefellasleep

while

(hewas)studyinghisgrammarbook.

whiledoing

anexperiment.

做实验时务必按照老师的话去做。Shefellasleepwhilelisteningtotheradio.她听着收音机睡着了。

也常用来表示原因，一般用来表示补充说明辅助性理由或提供上文未交代的情况。Since

youdon’tliketodoit,I’llasksomeoneelse.AsIhaveadayofftoday,I’llwritetoyou.3.as和since说明的是已为人们所知的理由。可用because代替，since的语气比because弱，比as强。since和as引导的从句一般放在句子的开头，as引导的从句有时可放于句末。Nowthat

Iamfree,Icanenjoymusicforawhile.4.nowthat,seeingthat,consideringthat

等也可以用来引导原因状语从句，有时可以先表示一种情况，再加以推论。that可以省去。1.Theteachermustbestrictwithyou_______theywantyoutomakegreatprogress.(because,as,since)2.______yourfatheriswellagain,younolongerhaveanythingtoworryabout.(because,since)______shewastheoldestinherfamily,shehadtolookafterthem.(because,as)becauseSinceAsFinishthe
