英语常用被动语态用法详解与练习

英语常用被动语态用法详解与练习在英语的万千表达中，被动语态扮演着不可或缺的角色。它不仅仅是一种语法现象，更是我们在特定语境下精准传达信息、突出表达重点的有效工具。相较于主动语态聚焦于“谁做了什么”，被动语态更侧重于“什么被做了”或“某事是如何被处理的”。对于英语学习者而言，熟练掌握被动语态的构成与用法，能极大地丰富语言表达，提升写作与阅读的深度。一、被动语态的构成被动语态的核心构成模式是“be动词+及物动词的过去分词(PastParticiple)”。其中，be动词的形式会根据句子的时态、人称和数进行相应变化，而过去分词则保持不变。基本结构：*主语(动作的承受者)+be动词+过去分词+(by+动作的执行者，可选)例如：*Active:ManypeoplespeakEnglish.(很多人说英语。)*Passive:Englishisspokenbymanypeople.(英语被很多人说。)常用时态的被动语态构成示例：*一般现在时：am/is/are+过去分词*Thelettersaretypedeveryday.(这些信每天都被打印。)*一般过去时：was/were+过去分词*Thisbookwaswrittenin2005.(这本书写于2005年。)*一般将来时：willbe+过去分词/am/is/aregoingtobe+过去分词*现在进行时：am/is/arebeing+过去分词*现在完成时：have/hasbeen+过去分词*Theworkhasbeenfinished.(工作已经被完成了。)二、被动语态的常见用法了解被动语态的构成是基础，更重要的是理解在何种情况下使用被动语态能让表达更得体、更符合英语习惯。1.当动作的执行者不明确、不重要或我们不知道时：*Thewindowwasbrokenlastnight.(窗户昨晚被打破了。)——我们可能不知道是谁打破的，或者谁打破的并不重要。*Thisancienttemplewasbuilthundredsofyearsago.(这座古庙建于数百年前。)——具体的建造者无从考证或无需提及。2.当我们想强调动作的承受者（即句子的主语）时：*Ourteamwasawardedthefirstprize.(我们队获得了一等奖。)——强调“我们队”这个承受者。3.在正式的书面语中，尤其是科技文献、新闻报道、官方文件等，为了体现客观性和正式性：*Theexperimentwasconductedunderstrictconditions.(实验是在严格条件下进行的。)*Newpolicieswillbeimplementednextquarter.(新政策将在下个季度实施。)4.为了使句子结构平衡或上下文连贯：*Aftertheaccident,theinjuredweretakentohospitalimmediately.(事故发生后，伤者立即被送往医院。)——如果用主动语态“Peopletooktheinjuredtohospital...”，会使“people”这个泛指的主语显得多余。5.当动作的执行者是“人们”、“有人”等不确定的群体时：*Itisbelievedthatshewillrecoversoon.(人们相信她很快会康复。)——也可以表达为"Sheisbelievedtorecoversoon."三、主动语态变被动语态的基本步骤1.找出主动句中的宾语，将其作为被动句的主语。2.根据主动句的时态和被动句的主语人称及数，确定相应的be动词形式。3.将主动句中的谓语动词变为其过去分词形式。4.如果需要强调动作的执行者，用介词“by”引出，置于句末；如果不需要，则省略。示例：*Active:Tom(主语)writes(谓语)aletter(宾语)everyday.*Passive:Aletter(原宾语，现主语)iswritten(be+过去分词)byTom(执行者)everyday.不同时态的转换示例：*一般过去时：Active:Theybuiltthebridgein1990.Passive:Thebridgewasbuiltin1990(bythem).*一般将来时：Active:Wewillholdthemeetingtomorrow.Passive:Themeetingwillbeheldtomorrow(byus).*现在进行时：*现在完成时：Active:Shehasfinishedherhomework.Passive:Herhomeworkhasbeenfinished(byher).四、需要注意的几个问题*错误:Theaccidentwashappenedyesterday.*正确:Theaccidenthappenedyesterday.*有些动词短语在变为被动语态时，要保持其完整性，不可遗漏介词或副词。*Active:Theylookafterthechildrencarefully.Passive:Thechildrenarelookedaftercarefully(bythem).*Active:Weshouldtakegoodcareoftheold.Passive:Theoldshouldbetakengoodcareof(byus).*感官动词（如see,hear,watch,notice,feel等）和使役动词（如make,let,have等）在主动语态中接不带to的不定式作宾补，变为被动语态时，不定式符号to要还原。*Active:Wesawhimenterthebuilding.Passive:Hewasseentoenterthebuilding(byus).五、实战练习练习一：将下列主动句改为被动句1.PeoplespeakChineseinmanycountries.3.Thestudentsarecleaningtheclassroomnow.5.Theyhavefinishedtheprojectontime.练习二：用括号内所给动词的适当被动形式填空1.Thisbook______(write)byafamousauthor.2.Theproblem______(discuss)atthemeetingyesterday.3.Anewhospital______(build)inourcitynextyear.4.Theflowers______(water)bymymothereverymorning.5.Itisreportedthatthemissingchild______(find)safeandsound.练习三：选择最佳答案填空1.Manyaccidents______bycarelessdriving.A.causeB.arecausedC.causedD.werecausing2.Theletter______byTomyet.A.hasn'twrittenB.haven'tbeenwrittenC.hasn'tbeenwrittenD.wasn'twritten3.English______allovertheworld.A.speaksB.isspeakingC.isspokenD.spoke4.Ithinkthisbook______bymostofthestudents.A.willlikeB.willbelikedC.islikingD.likes5.Thethief______bythepolicewhenhewastryingtoescape.A.catchesB.caughtC.wascaughtD.iscaught练习答案练习一：1.Chineseisspokeninmanycountries(bypeople).3.Theclassroomisbeingcleanedbythestudentsnow.5.Theprojecthasbeenfinished(bythem)ontime.练习二：1.iswritten2.wasdiscussed3.willbebuilt/isgoingtobebuilt4.arewatered5.hasbeenfound练习三：1.B2.C3.C4.B5.
