【专题】动词的时态与被动语态
语法专项突破
考频分析
初三外研版中,动词的时态与被动语态是重点语法模块,考频占语法总量的15%左右,贯穿试卷
所有核心题型:单项选择2-3题、完形填空3-4题、语法填空2-3题、书面表达核心考察,直接影
响句子完整性与准确性。在语境理解类题目中,动词的时态、语态及词义辨析往往是解题关键。
考查内容
·基本时态:一般现在时、一般过去时、一般将来时、现在完成时的构成(含肯定句、否定句、疑问
句)及时间状语匹配
。被动语态:各时态被动结构(am/is/are+done,was/were+done,will be+done,have/has been-+done)的
转换规则与语境选择
知识点一:动词的时态与被动语态
1.一般现在时(表示经常性、习惯性动作或客观事实)
。主动语态结构:主语+动词原形动词第三人称单数(主语为第三人称单数时)
例句:She often reads books in the library.
·被动语态结构:主语+am/is/are+动词过去分词
例句:This book is read by many students
2.一般过去时(表示过去某个时间发生的动作或存在的状态)
·主动语态结构:主语+动词过去式
例句:He visited the Great Wall last year.
·被动语态结构:主语+was/were+动词过去分词
例句:The Great Wall was visited by him last year.
3.一般将来时(表示将要发生的动作或存在的状态)
。主动语态结构:主语+will/shall+动词原形或主语+an/is/are going to+动词原形
例句:They will have a picnic tomorrow./She is going to buy a new dress.

·被动语态结构:主语+wil/shall be+动词过去分词或主语+an/is/are going to be+动词过去分词
A picnic will be had by them tomorrow./A new dress is going to be bought by her.
4.现在进行时(表示正在进行的动作)
·主动语态结构:主语+am/is/are+动词现在分词
例句:She is singing a song now.
·被动语态结构:主语+am/is/are+being+动词过去分词
例句:A song is being sung by her now
5.过去进行时(表示过去某一时刻正在进行的动作)
·主动语态结构:主语+was/were+动词现在分词
例句:They were playing basketball at4p.m.yesterday.
。被动语态结构:主语+was/were+being+动词过去分词
例句:Basketball was being played by them at4p.m.yesterday.
6.现在完成时(表示过去发生的动作对现在造成的影响或结果,或从过去一直持续到现在的动作)
·主动语态结构:主语+have/has+动词过去分词
例句:I have finished my homework already.
·被动语态结构:主语+have/has been+动词过去分词
例句:My homework has been finished by me already.
7.被动语态的基本用法(强调动作的承受者或动作本身,不知道或不必提及动作的执行者)
·基本结构:be+动词过去分词(be动词的形式随时态变化)
例句:The letter was written by Tom.(强调信被写,执行者是Tom)/Many trees are planted every
year.(强调种树这一动作,不必提及执行者)
知识点二:动词时态与被动语态的特殊用法及易错点
1.情态动词的被动语态
●结构:情态动词(can/may/must/should等)+be+动词过去分词
·例句:
1.The work must be finished today.
2.This book can be borrowed from the library.
2.感官动词和使役动词的被动语态
。感官动词(see/hear/watch/feel等)主动语态:see sb.do sth.(强调全过程);被动语态:sb.be
seen to do sth.(还原to)
例句:主动:I saw her go out.被动:She was seen to go out by me.

。使役动词(make/1et/have)主动语态:nake sb.do sth.:被动语态:sb.be made to do sth.(还原to)
例句:主动:The teacher made him stand up.被动:He was made to stand up by the teacher.
3.时态的混淆辨析
·一般过去时与现在完成时:一般过去时强调动作发生在过去,与现在无关:现在完成时强调过
去动作对现在的影响或持续到现在。
例句对比:He lived here in20l0.(一般过去时)/Ie has lived here since20l0.(现在完成时)
。过去进行时与一般过去时:过去进行时强调过去某时刻正在进行的动作;一般过去时强调过去
发生的短暂动作。
例句对比:I was reading a book when the doorbell rang
4.被动语态的特殊结构
·不及物动词无被动语态:如happen(发生)、appear(出现)、arrive(到达)等
例句:The accident happened yesterday.
。主动形式表被动意义:某些动词(如sell/wash/clean等)后接副词时,用主动表被动
例句:This kind of shirt sells well
5.将来时的其他表达
·be to do sth.(按计划或安排将要做某事)
例句:The meeting is to start at3p.m.tomorrow.
●be about to do sth.(即将做某事,不与具体时间状语连用)
例句:We are about to leave when it began to rain.
知识点三:动词的时态与被动语态
1.一般现在时的被动语态

。基础用法(中考必背):
1.表示经常性、习惯性的被动动作→例句:English is spoken by many people around the world.
2.客观事实或普遍真理→例句:The Great Wall is visited by millions of tourists every year.
3.主语是动作的承受者→例句:The classroom is cleaned by students every day.
。特殊考点(中考易错):

2.不及物动词无被动语态→例句:The sun rises in the east.
2.一般过去时的被动语态

解题小妙招
初三下册外研版
【寒假专版】
A版知识点全解
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:被动语态基本结构及时态匹配
核心:根据动作发生的时间和语境,判断被动语态中be动词的正确形式(体现时态)及动词过去
分词的使用
真题1(语法填空):
Many trees_(plant)in our city last spring.
答案:were planted
解析:由时间标志词'last spring'”可知,动作发生在过去,被动语态结构为”was/were+过去分词';
主语'Many trees'”为复数,be动词用were,plant的过去分词为planted。
真题2(单项选择):
A new library-in our school next year.
A.builds B.will be built C.is building D.was built
答案:B
解析:由时间标志词'next year'”可知,动作发生在将来,被动语态结构为”will be+过去分词',build
的过去分词为built,故选B。
考法二:主动语态与被动语态转换
核心:根据句子语境及动作关系,将主动语态句子转换为被动语态句子,需注意时态一致性及动词
过去分词正确形式
真题1(句型转换):
People grow rice in the south of China.(改为被动语态)
Rice in the south of China.
答案:is grown
解析:原句为一般现在时主动语态,主语'rice”是动作承受者,被动语态结构为”am/is/ae+动词过
去分词':主语为不可数名词,be动词用is,grow的过去分词为grown。
真题2(单项选择):
Many trees_on the hill last year.
A.plant B.planted C.were planted D.are planted
答案:C
初三下册外研版
【寒假专版】
A版知识点全解
解析:由时间标志词last year”可知用一般过去时,主语”trees”是动作承受者,被动语态结构
为'was/were+动词过去分词':主语为复数,be动词用were,plant的过去分词为planted。
考法三:时态与被动语态的综合运用
核心:结合时间状语判断时态,根据动作关系确定主动或被动语态,掌握不同时态被动语态的结构
及特殊用法(如情态动词被动、感官/使役动词被动还原o)
真题1(单项选择):
A new bridge_over the river now.Workers say it_in three months.
A.is built will finish
B.is being built will be finished
C.is building will be finished
D.is being built will finish
答案:B
解析:第一空由时间标志词”now”可知用现在进行时,主语”a new bridge”是动作'build的承受者,
需用现在进行时被动语态”is being built”;第二空由'in three months'可知用一般将来时,主语”it'指
桥,是动作'finish'”的承受者,用一般将来时被动语态”will be finished''。
真题2(语法填空):
The classroom_(clean)every day.We must_(keep)it tidy.Look!Some students-(clean)it now.
答案:is cleaned keep are cleaning
解析:第一空由”every day”可知表日常习惯,主语'the classroom”是动作”clean'”的承受者,用一般
现在时被动语态”is cleaned';第二空”must”后接动词原形keep”;第三空由'now”可知用现在进行
时,主语”some students'”是动作执行者,主动语态结构为'are cleaning”。
