【专题】一般过去时被动语态
语法专项突破
考频分析
教科版(五四制)9下Uit6中,一般过去时被动语态是重点语法点,考频占语法总量的10%左右,
主要出现在单项选择(1-2题)、语法填空(1-2题)、完形填空(1-2题)等题型中。在语境理解类
题目中,一般过去时被动语态的结构及用法辨析往往是解题关键。
知识点一:一般过去时被动语态专项突破
1.核心结构(过去被动的构成要素)
1.时态助动词:was(主语单数/不可数)/were(主语复数)
2.被动标志:动词过去分词(规则动词加-ed,不规则动词需特殊记忆)
3.完整公式:主语+was/were+过去分词+by+动作执行者,可省略)
例句:
。The letter was written by my brother.(主语单数,用was:write的过去分词为written)
·These books were bought last Sunday.(主语复数,用were;buy的过去分词为bought)
2.句式转换(四大基础句式变形)
1.肯定句:主语+was/were+过去分词
例:The bridge was built in1998.(这座桥建于1998年)
2.否定句:主语+was/were+not+过去分词
例:The meeting was not held yesterday.(会议昨天没举行)
3.一般疑问句:Was/Were+主语+过去分词?
例:Were these photos taken by your father?(这些照片是你爸爸拍的吗?)
4.特殊疑问句:疑问词+was/were+主语+过去分词?
例:When was the new school built?(新学校是什么时候建成的?)
3.语境应用(教材单元重点场景)

Unit6知识点精解
1.人物经历描述(Unit6 Wilma相关)
例:Wilma was called"the black pearl'by people..(威尔玛被人们称为”黑珍珠”)
2.历史事件陈述
例:The first Olympic Games were held in Greece..(第一届奥运会在希腊举办)
3.物品来源说明
例:This storybook was given to me by my teacher..(这本故事书是老师送给我的)
4.易错点警示(初中生高频错误)
l.be动词误用:主语为单数时误用were(如:The song were sung→was sung)
2.过去分词混淆:不规则动词记错(如:break→broken而非breaked)
3.主动被动混淆:有明确过去时间时误用主动态(如:The work finished yesterday→was finished)
知识点二:一般过去时被动语态
1.基本结构
1.肯定句:主语+was/were+过去分词
→例句:The story was written by Lu Xun.
2.否定句:主语+was/were+not+过去分词
→例句:The letter wasn't sent yesterday.
3.一般疑问句:Was/Were+主语+过去分词?
→例句:Were the books bought last week?
2.用法拓展(中考核心)
1.动作承受者作主语时使用
→例句:The window was broken by Tom.
2.不知道动作执行者时使用
例句:This song was sung all over the country.
3.强调动作本身时使用
→例句:A new hospital was built in our city last year.
3.特殊句式(中考易错)
1.含情态动词的被动(情态动词+be+过去分词)
→例句:The work should be finished on time.

→原句:They invited her to the party..
→被动:She was invited to the party by them.
解题小妙招
时态语态妙招
时态判断看标志,没有标志品语境:
主动结构记”主谓”,被动必带be和done”;
被动中be最关键,记住be就OK;
一现被动”am/is/are”,一过被动'was/were';
进行被动要用being'’,完成被动have/has/had been'”;
将来被动'will be'”,最后加上一个done。
考法精析
考法一:一般过去时被动语态结构辨析
核心:根据主语单复数及动词特征,正确使用'was/were+过去分词?结构并避免常见错误
真题1(语法填空):
The old house_(build)in 1990.Now it still looks strong.
答案:was built
解析:由时间标志词”im1990”可知用一般过去时;主语house'”为单数,be动词用was;build的过
去分词为built。.
真题2(单项选择):
These books_to the library last week.
A.are returned B.were returned C.returned D.was returned
答案:B
解析:由时间标志词'last week'”可知用一般过去时;主语books”为复数,be动词用were;return的
过去分词为returned,.构成被动语态。
考法二:主动被动转换与语境应用
核心:结合具体语境,将主动句转换为一般过去时被动句,注意主谓一致和过去分词正确形式
真题1(语法填空):
The workers-(build)a new bridge over the river last year.Now people can cross the river easily.
答案:built
解析:主动句中,主语The workers为动作执行者,时间标志词'last year''表明用一般过去时,build
的过去式为built

真题2(句型转换):
People planted many trees in the park last spring.(改为被动句)
many trees_in the park last spring?
答案:Were planted
解析:主动句宾语many trees变被动句主语,主语为复数,be动词用were;plant的过去分词为planted,.
一般疑问句将were提前
考法三:一般过去时被动语态的语境应用与句式转换
核心:结合具体语境(如历史事件、人物经历)判断被动语态的使用,掌握一般过去时被动语态的
四大句式转换及易错点规避
真题1(单项选择):
The first Olympic Games_in Greece in 776 BC.They are very important in history.
A.held B.were held C.are held D.was held
答案:B
解析:主语“The first Olympic Games”是动作“hold”的承受者,需用被动语态;由时间标志“in
776BC”可知用一般过去时,主语为复数,be动词用were,hold的过去分词为held。
真题2(语法填空):
These photos_(take)by my father during his trip to Beijing last summer.Look how beautiful they are!
答案:were taken
解析:主语“these photos'”是动作“take”的承受者,用被动语态;时间标志“last summer'”提示
用一般过去时,主语为复数,be动词用were,take的过去分词为taken。.
