1、如何将主动语态变为被动语态?被动语态:(一)主动语态表示主语是谓语动词动作的执行者，被动语态表示主语是谓语动词动作的承受者，不及物动词没有被动语态形式，主动语态和被动语态的变换如下：主动语态：(二)被动语态基本结构:be+动词过去分词,，不同时态的被动语态中“be”的形式不同，一般现在时的被动语态为:am/is/arc+动词过去分词，有时“by+宾语”可以省掉ManpeoplespeakEnglish.―►Englishisspokenbymanypeople.TheymakecomputersintheUSA..—►Computersaremade(bythem)inthe

2、USA.Peopleuseknivesforcuttingthings.―►Knivesareusedforcuttingthings.TheygrowriceinSouthChina.―►RiceisgrowninSouthChina.如何运用一般现在时被动语态的句型？厂肯定式ItisproducedinChina.J杏定式Itisn'tproducedinChina一般疑问式IsitproducedinChina.?(Yes,itis./No,itisn't)特殊疑问式Whereisitproduced?肯建式Manytreesareplantedinspring.I否定

3、式Manytreesaren^plantedinspring.一般疑问式AremanytreesplantedinSpring?(Yesjheyare./No,theyaren't.)特殊疑问式Whenaremanytreesplanted?▲被动语态应注意的几个问题：不及物动词带介词和介词宾语，在变为被动语态时，仍然要带上介词，如1Theteacherislistenedtocarefullybythestudentsinclass.2Thenewstudentsarelookedafterintheschool.3Thethingsaretakegoodcareof・当动

4、词带有符合宾语时，并且宾补是省去“to”的动词不定式时,在被动语态中应加上“to”,4Theymakeusdoallthework.Weam>radetodoallthework.5WeoftenhearhersingEnglishsongs.She-hr^ftenheardtosingEnglishsongs.6Iseehimwalktoschool.Hetowalktoschool.当动词带双宾语时，将其中一个宾语提前作被动语态的主语，另一个不动；如果是将指物或指事的宾语提前，则指人的宾语前应加上“10”如：7TheygivemesomepresentsIamgivens
