一、被动语态构成形式
被动语态由“be+及物动词的过去分词”构成。不及物动词没有被动语态。在不同的时态下助动词be有不同的形式。
1.一般现在时:You are ordered to do it.
①The temperature will fall sharply the day after tomorrow,when a snowstorm ________ to strike our area.
C.is expected
解析:句意:届时会有暴风雪。be expected to“预计会做某事”。
答案:C
2.一般过去时:I was invited to the concert.
②The way the guests ________ in the hotel influenced their evaluation of the service.
A.treated
C.would treat
解析:句意:客人们在旅馆中被招待的方式影响到对他们服务的评价。此题考查时态语态。根据题意,客人是被招待的,应排除A、C两项;influenced 时间提示为一般过去时,故选B。
答案:B

by Dutch explorers in 1606,the eastern half of Australia ________
C.was claiming
解析:由句意:自1606年被荷兰探险者发现之后,澳大利亚东半部分在1770年宣布为英国所有,知答案选A。
答案:A
3.一般将来时:The matter will be looked into tomorrow.
④________ is known to us is that the 2012 Olympic Games ________ in London.
解析:由句意知空中应填一个引导主语从句的连接词,并作句子的主语;由句中的时间2012年知表将来,且Olympic Games与hold之间为被动关系。综上选A。
答案:A
⑤If your order is ready,the T-shirt ________ to you as soon as possible.
A.has delivered
C.will deliver
解析:主语是T-shirt 谓语动词,deliver 应用被动,表示T-shirt被送,排除A、C两项。根据语境,如果你定了货,T-shirt 将会随时被送货。故选D项。
答案:D
⑥—A meeting ________ at 3 pm. next Tuesday.
—Will you go there?
A.has held
C.will be held

答案:C
4.现在进行时:The house is being built.
⑦—Why don't we choose that road to save time?
—The bridge to it ________.
A.has repaired
C.is being repaired

答案:C
⑧Would you please keep silent?The weather report ________ and I want to listen.

答案:B

A.had not been heard of

答案:B

—Half ________ when you come back.
A.has been done

答案:D
10.含有情态动词的被动语态:情态动词+be+动词的过去分词
These books must be returned in three days.

Teacher Wang got married last year.
16. At minus 130℃,a living cell can ________ for a thousand years.
A.preserve
C.be preserving
解析:考查情态动词用法。can 后面接动词原形,同时应注意被动语态。句意为:在零下130℃时,活细胞可以存活一千年。
答案:B
二、主动形式表示被动意义的情况
1.—Honey,this is a present for your birthday.

C.is wearing
解析:it wears comfortable 它穿起来很舒服。
答案: A
2.—I'd like a pen which ________ well.
—Will this one ________?
A.writes; help
C.is written; work
解析:考查动词的语态和动词辨析。第一空表示“一支好用的钢笔”,用主动语态而不用被动,因此空白处填writes。答语说:这支笔可以吗?表示“行,可以”用动词do。
答案:B
3.Our house has reached the point where so many things need ________ and it's so hard to find the time to fix them.
A.to do up
C.to put up
答案:B
三、被动语态与系表结构的区别
被动语态表示动作,主语是动作的承受者;而系表结构则表示主语的特征或所处的状态。
1. Mom's spent the day shopping,cleaning and cooking and now she________.
A.has worn out
C.is wearing out
解析:本题的第一分句用的是现在完成时,再根据时间状语now可知指现在状况,所以用一般现在时,be worn out意为“筋疲力尽”。
答案:B
四、“get+过去分词”结构的用法
1. —Do you know how much a babysitter ________ for an hour?
—Well,it depends.
A.pays
C.being paid
解析:根据句意“你知道一个保姆一小时挣多少钱吗”可知答案为B。
答案:B
2. —What's wrong with your leg?
—It ________ in a car accident.
A.has been hurt
C.hurt
解析:考查谓语动词的时态和语态。答语意为:在一次车祸中受伤了。主语It即指my leg,为谓语动词动作的承受者,因此需要用被动语态;车祸发生在过去,因此应用一般过去时。这里got hurt=was hurt。
答案:B
