时间状语从句及练习
时间状语从句常见的从属连词有:
(注意其汉语意义)
when,while,as,before,after,since,until(till)onceassoonas,themoment,theminute,immediately,directly,each/everytime,thefirsttime,thelasttime,nexttime,bythetime,whenever等。
例如:
Every/EachtimeIwasintrouble,hewouldcometomyhelp.
IthoughtherniceandhonestthefirsttimeImether.
注意:
(1)when,while,as的区别:
1)when引导从句时,主从句的动作有先有后,也可以同时进行,从句的动作可以是持续性的,也可以是短暂的。
如:
WhenIgottotheairport,theplanehadalreadytakenoff.(主先从后)(短暂性)
WhenIlivedthere,IusedtogototheseasideonSundays.(同时)(持续性)
Whenthemovieended,thepeoplewentback.(从先主后)
2)while侧重主从句动作的对比,且从句的动词必须是持续性的。
如:
Whilewewerechattingshewaslookingatthetimetableonthewall.
3)as引导从句时侧重主从句动作同时或几乎同时进行,从句的动作可以是持续性的,也可以是短暂的。
如:
SometimesIwatchTVasIamhavingbreakfast.
4)when和while还可以是并列连词,意思分别是“就在这时”,“然而”。
如:
Iwashavingarestonthesofawhenthetelephonerang.
Theyweresurprisedthatachildshouldworkouttheproblemwhiletheycouldn’t.
注:
并列连词when常用与以下句型中:
①…was/weredoing…when…(正在做…突然)
②…was/wereabouttodo…when…(刚要做…突然)
③…was/wereonthepointofdoing…when…(刚要做…突然)
④…hadjustdone…when….(刚一…就)
⑤Hardly/Scarcelyhad…done…when…(刚一…就)
(2)before引导从句时,词义非常灵活,注意下列句子中的before的词义:
1.BeforeIcouldgetinaword,thetailorhadmeasuredme.(还没来得及…就)
2.Wehadn’trunamilebeforehefelttired.(还没…就)
3.Wehadsailed4daysbeforewesawland.(…才…)
4.Pleasewriteitdownbeforeyouforgetit.(趁还…没就)
(3)till(until)和not…till(until)
1)till(until):
主句谓语动词必须是持续性的,意思是“到…为止“如:
Heremainedtheretill/untilshearrived.
2)not…till(until)…:
主句谓语动词必须是短暂性的,意思是“直到…才”如:
Shewon’tgotobedtill/untilhereturnshome.
3)not…until还有强调式和倒装式:
强调句:
Itisnotuntilhereturnshomethatshewillgotobed.
倒装句:
Notuntilhereturnshomewillshegotobed.
(4)几个极易混淆的时间状语从句:
1)Itwas+时间点+when…(当的时候时间是)
Itwas5amwhenwearrivedatthevillage.
2)Itwas/willbe+时间段+before…(没过…就/过了…才)
Itwas/willbetwoweeksbeforewemet/meetagain.
3)Itis/hasbeen+时间段+since…(自从…以来有…)
Itis/hasbeen3yearssincewelastmet.
突破点:
一看be动词的时态,二看时间段还是时间点。
注意:
在“Itis/hasbeen+时间段+since…”句型中,从句的动词必须是短暂性的,如果是延续性的动词,时间要从从句的动作结束时算起。
如:
Itis3yearssinceIsmoked.(我戒烟有三年了)
补充:
assoonas,immediately,directly,instantly,themoment,theminute,theinstant,nosooner…than…,hardly/scarcely….when….和once这些从属连接词引导的从句都表示从句的动作一发生,主句的动作随即就发生,常译为“一…就…”。
从句中一般时态代替将来时态。
everytime,eachtime,nexttime,thefirsttime,anytime,allthetime等名词短语用来引导时间状语从句,表示“每当…..,每次…..;下次……”等。
