PassivevoiceinthesimplepresentandpasttensesUnit7Grammar语态是动词的一种形式，表示的是主语和谓语之间的关系。英语中的语态有两种：主动语态和被动语态。当主语是谓语的执行者时，用主动语态。当主语是谓语的承受者时，用被动语态。如：Wecleantheclassroomeveryday.我们每天都打扫教室。Theclassroomiscleaned(byus)everyday.教室每天都被(我们)打扫。1.ThecakewaseatenbyDaniel.2.Nancyboughtabookyesterday.3.ThelittledogislookedafterverywellbySimon.4.HeisreadingEnglish.5.Thecomputerisboughtbymyuncle.6.Iamwokenupbymyfathereverymorning.Underlinethepassivevoiceinthefollowingsentences.Noneofthebookswastakenaway.没有一本书被拿走。动作的执行者是泛指或者不言自明时。被动语态的基本用法Thetoyisdesignedforchildren.在不知道动作的执行者是谁时。这款玩具是为孩子们设计的。需要强调动作的承受者时。Mybikewasrepaired.我的自行车修好了。MrWuislikedbyallofhisstudents.所有的学生都喜欢吴老师。在被动语态的句子中,如果我们需要指出动作的执行者,可以由by引出。被动语态的基本构成主语be动词过去分词一般现在时Iamsupported.You/We/TheyareHe/She/Itis一般过去时Iwassupported.You/We/TheywereHe/She/Itwas主动语态和被动语态的句式转换主动语态主语She谓语(主动式)hurt宾语me.被动语态原宾语(改为主格)I谓语(被动式)washurtby原主语(改为宾格)her.areplannedtohelpthepoorWhattheydoeveryyear1.Charityactivities_________________________(plan/tohelpthepoor).arehandedouttopeopleLeaflets__________________________________________________(handout/topeopleinthestreet/volunteers).inthestreetbyvolunteersToysandCDs_____________________(sell/toraisemoney).aresoldtoraisemoneyWhattheydidlastweekNewbooks___________________________________________________________(send/tochildreninpoorareas/theClass1,Grade8students).weresenttochildreninpoorareasbytheClass1,Grade8studentsWarmclothes__________________________(collect/forpoorpeople).werecollectedforpoorpeopleAcharityshow_____________________________(hold/theStudents’Union).washeldbytheStudents’Union1.Reviewthecontentsofthislesson.2.Finishtheexercisesintheworkbook.3.Previewthenextlesson.
