练习5 主动表被动
一、单项选择
从每小题所给的A、B、C、D四个选项中选出一个可以填入空白处的最佳选。
1.That river _____ 250 kilometers long and 60 meters wide.
A.measures
B.is measured
C.calculates
D.is calculated
【答案】A
【详解】考查动词辨析和主动表被动。句意:那条河长250公里,宽60米。measure表示“测量”,描述主语的属性时,用主动表被动,calculate表示“计算”,此处指河流的长宽等自然属性应用measure。故选A。
2.I like getting up very early in summer. The morning air is so good .
A.to be breathed
B.to breathe
C.breathing
D.being breathed
【答案】B
【详解】考查不定式。句意:我喜欢夏天早起。呼吸早晨的空气是有益于身心的。形容词后面用不定式,主动表被动,故选B。
3.— What do you think of my composition?
— It_____well______ a few spelling mistakes.
A.reads; except for
B.read; besides
C.is read; except for
D.is read; besides
【答案】A
【详解】考查语态及介词短语辨析。句意:-你认为我的作文怎么样?-读起来不错,除了一点拼写错误。当read用作不及物动词,表示主语的某种属性时,通常用主动形式表示被动意义,通常与well,easily,slowly等副词连用。besides 译为“除了什么之外,还有…”。虽然含有“除了”之意,但重点是“还有”,相当于in addition to。而except for 则表示一种排除关系,意思是“除了什么之外,不再有…”,把...除外,通常放于句首。故选A项。
4.This wall requires______.
A.to repair
B.repaired
C.repairing
D.being repaired
【答案】C
【详解】考查主动表达被动。句意:这堵墙需要修理。此处考查短语require doing sth.“需要(被)”,此处用主动表被动,故选C项。
5.I find these problems are easy ________________.
A.to be worked out
B.to work them out
C.to work out
D.to be worked them out
【答案】C
【详解】考查主动表达被动。句意:我发现这些问题很容易解决。“名词(代词)+ be easy(difficult, fit等形容词) + 不定式” 结构中,有时尽管主语是动作的承受者,不定式在意义上是被动,形式上却是主动,句中these problems是work out的宾语。故选C。
6.This clock needs ______, for it is five minutes ______.
A.to be repairing; slow
B.be repaired; slower
C.repairing; slow
D.being repaired; slowest
【答案】C
【详解】考查need主动表被动的用法。句意:这块钟需要修理,因为它慢了5分钟。第一空处考查need的用法,need doing = need to be done需要被……;第二空因为没有进行对比,故用形容词的原级,故选C项。
7.We all feel it is Jack as well as his wife that ________for their son’s bad performance at school.
A.are to blame
B.is to be blamed
C.are to be blamed
D.is to blame
【答案】D
【详解】考查blame用法和主谓一致。句意:我们感觉Jack和他的妻子应该为他们的儿子在学校的糟糕表现负责。固定词组be to blame应受责备。该词组用主动语态表示被动含义。本题的主语是Jack,故使用单数形式。故D正确。
