动作不知道，说出谁做的没有必要；动作承受者需强调，被动语态运用到。四、主动语态变被动语态的方法(1)把主动语态的宾语变为被动语态的主语。(2)把谓语变成被动结构(be＋过去分词)(根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式)。(3)把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。例如：Allthepeoplelaughedathim.Hewaslaughedatbyallthepeople.Theymakethebikesinthefactory.Thebikesaremadebytheminthefactory.口诀3：宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过分”来使用。五．主动语态的注意事项:不及物动词和词组不用被动语态.Thatpendoesn’tbelongtoMary.及物动词词组在被动语态中不可丢掉的词组中的介词.Theblindboyshouldbetakengoodcareof.主动结构的主语变为介词by的宾语,组成介词短语,在被动结构中位于动词之后;但在动作执行者无须说明或不必强调时,by短语可省略.ManypeoplespeakEnglish.Englishisspokenbymanypeople.Theboywastoldtogotobed.thesecondperiodTeachingaims:Toenablestudentstodothefollowing:1.learnTuningIn&thetext2.practiceonthesentencepatternorallya.Itisusedfordrinkingandrecreation.Itisalsousedinfarmingandindustry.b.Thelesswaterwewasteorpollute,themorewewillhavefortomorrow.3.describewaterresources4.talkaboutwaterproblemsI.Revision
