1、被动语态（ThePassiveVoice).主动语态与被动语态：英语动词有两种语态,即主动语态(TheActiveVoice)与被动语态（ThePassiveVoice)。主动语态表示主语是动作的执行者;被动语态表示主语是动作的承受者。e.g.1.TheymaketrainsinZhuzhou.TrainsaremadeinZhuzhou.2.Thefarmersgrowcottoneveryyear.Cottonisgrownbythefarmerseveryyear.主动语态被动语态主动语态被动语态e.gManypeoplespeakEnglish.Englishi

2、sspokenbymanypeople.主动语态变被动语态的步骤：1、主动语态的宾语变为被动语态的主语；2、主动句的谓语动词变为被动结构；3、主动句的主语变为被动句的宾语，由by引出，当不强调动作的执行者时，常省略。4.其它成分不变。变被动语态时需要注意的事项一变二套三注意宾变主，主变宾，宾语前面by跟，谓语动词变过分，不忘前面be动词跟套时态，主被动时态一致注意因人称的变化而引起的主谓一致问题。各种时态的被动语态的构成：1.一般现在时态am,is,are+过去分词2.一般过去时态was,were+过去分词3.一般将来时态will+be+过去分词4.过去将来时态woul

4、dformakingtables.3、TheyaremakingcomputersintheUSA.EnglishisspokeninCanada(bythem).Woodwasusedformakingtables.ComputersarebeingmadeintheUSA.把被动句变否定Computersaren’tbeingmadeintheUSA.4、TheyhavegrownriceinSouthChina.5.Wemustplantmoretreesnextyear.6.Iamgoingtocleanourclassroomtomorrow.Moretree

5、smustbeplantednextyear.Ourclassroomisgoingtobecleanedtomorrow.RicehasbeengrowninSouthChina.把被动句变疑问.HasricebeengrowninSouthChina？变被动语态的特殊情况一。双宾语双宾语由直接宾语和间接宾语组成。主语+及物动词+间接宾语+直接宾语直接宾语是谓语动词的承受者，间接宾语表示谓语动作的方向（对谁做）或动作的目标（为谁做），间接宾语紧接在谓语动词后，但它不能单独存在。它和直接宾语组成双宾语。e.g.:Theygavehimawatch.这里的him是间接宾语

6、,awatch是直接宾语,变被动语态的特殊情况一、双宾语buy/makesbsth=buy/makesthforsbgivesbsth=givesthtosb1.Myfatherboughtmeacomputer.Acomputerwasboughtformebymyfather.Iwasboughtacomputerbymyfather.2.Hegivesmeabook.Abookisgiventomebyhim.IamgivenabookbyhimSth+be+过去分词+for/tosb+bysb.Sb+be+过去分词+sth+bysb双宾语改为被动语态1Hegav
