在句中是不及物动词，后面不能直接带宾语，因此不能变为被动语态。不及物动词（vi.)不能用于被动语态。happen,takeplace,appear,disappear,belongto,breakout(爆发）

e.g.Atrafficaccident________(happen)justnow.happened2.连系动词（Link.v.)不用被动语态。如：be,look,seem,feel,sound,smell,taste,get,turn,become…

e.g.PekingOpera_______(sound)beautiful.sounds

3.当此动词表示事物的自然属性的时候，不用被动语态。e.g.Thepen__________(write)veryfast.writesThiskindofsweater_______(sell)well.sells三、汉语中含有“据说”、“据悉”、“有人说”、“大家说”等时。例如：Itissaidthatonedayheclimbedtothetopofahouseand……ItwasreportedthathermotherdiedofSARS.众所周知……Itiswellknownthat…据推测说……Itissupposedthat…1.---DidyougotoJim’sbirthdayparty?---No,I_____(北京2003年中招试题)A.amnotinvitedB.wasn’tinvitedC.haven’tinvitedD.didn’tinvited2.Tomakeourcitymorebeautiful,rubbish______intotheriver.A.needn’tbethrownB.mustn’tbethrownC.can’tthrowD.maynotthrow(重庆2003年中招试题)中招名题回顾BB考点聚焦1、主动语态为动词原形作宾语补足语。Theworkersweremade
