语法
1.一般过去时的被动语态结构式:
(1)肯定句:主语+ was /were+ 动词的过去分词 +(by+人称代词宾格)+ 其他
eg:A sweet song was sung by her on the stage.
(2)否定句:主语+ was /were+ not + 动词的过去分词 +(by+人称代词宾格)+ 其他?
eg:A sweet song wasn’t sung by her on the stage.
(3)疑问句:Be(Was/Were)+主语+动词的过去分词+(by+人称代词宾格)+其他?
eg:Was a sweet song sung by her on the stage
(4)特殊疑问句:What/Where/ When +was /were +主语+动词的过去分词+ 其他?
eg:Where was a sweet song sung by her?
2.被动语态需要注意的几个方面:
(1)在主动句中,使役动词make,let,have,感官动词 see,hear,feel,watch,notice等后接省略to的动词不定式作宾语补足语,在变成被动语态时,后面的不定式需加上“to”。
eg: My mother makes me get up early every day.
= I am made to get up early every day by my mother.
(2)有些词,如系动词taste, feel, look, sound等常用主动语态表达被动的意思。
eg: The voice sounds nice.
(3)主动语态的句中若有双宾语,变被动语态时,可将间接宾语(人)变为被动句的主语,而把直接宾语(物)留作被动句的宾语;或把主动句的直接宾语变为被动句的主语。此时间接宾语前常用介词for或to等来连接。
eg: He bought me a book.
=I was bought a book by him.
=A book was bought for me by him.
(4)有些动词,如happen, belong等没有被动语态。
eg: The bike belongs to me.这辆自行车属于我。
3.被动语态的运用:
(1)不知道谁是动作的执行者或没有必要知道谁是动作的执行者时。
The house is quite old. It was built in 1950.
这座房子太旧了,它是1950年建的。
When will the road be opened to traffic?
这条路什么时候通车?
(2)需要强调动作的对象即宾语时。
Calculator can't be used in the math exam.
计算器不能用于数学考试。
He was awarded first prize in that contest.
他在比赛中获得了第一。
(3)有时为了礼貌等原因不愿说出行为者,这时也常用被动语态。
The construction of the new lab must be completed by the end of next month.
新实验室必须在下个月底前完工。
You are requested to give a performance.
请你给我们表演一个节目。
4.主动句变为被动句所遵循的4个步骤:
(1)把原主动句中的宾语变为被动句的主语。
(2)把动词变为被动形式即be+过去分词,并注意其人称和数随主语的变化,而动词的时态则保持不变。
(3)原主动句的主语如需要则放在by后面以它的宾格形式出现(注代词的宾格),如不需要则可省略。
(4)其它的成分(定语、状语)不变。
The naughty boy broke the window yesterday. (主动语态)
The window was broken ( by the naughty boy) yesterday. (被动语态)
