被动语态“五注意”动词的被动语态在语法中起着举足轻重的作用,也是历年高考考查的重点
在学习时我们应注意以下几点:一、掌握被动语态的时态动词的被动语态是由动词be加上过去分词构成,时态通过be表现出来
如:Breakfastisprovidedinourhotelfrom7to9o’clockonweekdays
(一般现在时的被动语态)Wehaven’tmovedintothenewhousebecausetheroomsarebeingpainted
(现在进行时的被动语态)Thesportsmeetwillbeputoffbecauseofthebadweather
(一般将来时的被动语态)Twobigtowerswerebeingbuiltthereatthattime
(过去进行时的被动语态)Myhometownwasliberatedin1949andnowithasbeenturnedintoabeautifulcity
(一般过去时的被动语态)Thedoctorhasalreadybeensentfor
(现在完成时的被动语态)Whenfirefightersarrived,thebigfirehadbeenputout
(过去完成时的被动语态)二、注意短语动词的被动语态有不少短语动词相当于及物动词,所以这些短语动词亦有被动语态
如:Manyinterestingexperimentsarecarriedoutinourlaboratory
Heisoftenmadefunofforthisbyhisclassmates
有些由“动词+名词+介词”构成的短语动词,变成被动语态时可以将其中的名词变为被动语态的主语
如:Gooduseismadeofthelibrary
(主动句是:Theymakegooduseofthelibrary
)三、不及物动词没有被动语
