疑问式Am/Is/Are+主语+过去分词(+by…)?特殊疑问词+am/is/are+主语+过去分词（+by...)?助记：被动不离“be”“p.p.”,“p.p.”前面助动be。主谓一致莫忘记，am,is,are现在时。2.一般现在时被动语态的基本用法

用法

分词”结构；第三步:将主动语态的主语改为介词by的宾语，放在谓语之后(有时可省略)。如图示：They(主语）grow(谓语）tea(宾语）inthesouth-eastofChina.被动语态:主动语态:Tea(主语）isgrown(谓语）bythem

inthesouth-eastofChina.含有情态动词的被动语态句式结构示例肯定句主语+情态动词+be+及物动词的过去分词(+by…)Teenagersshouldbeallowedtogoshopping.否定句主语+情态动词+not+be+及物动词的过去分词(+by…)Thewordcan’tbeusedinthissentence.一般疑问句情态动词+主语+be+及物动词的过去分词(+by…)?Musttheworkbefinishedtoday?特殊疑问句特殊疑问词+被动语态的一般疑问句？Whoshouldbeaskedforhelp?含有情态动词的主动句变为被动句时，谓语动词部分改为“情态动词+be+及物动词的过去分词”。WecanwriteLetterscanbewrittenlettersinEnglish.inEnglishbyus.改为被动语态点拨4aRewritethesentencesaccordingtotheexample.shouldbeencouragedtodosocial3.CanLucydoherhomeworktomorrowinstead?Can__________________________________________________________________?Lucy’shomeworkbedonebyhertomorrowinsteadDoyouthinkwemustkeepteenagersawayfromtheInternet?Doyouthinkteenagers_________________________________________?mustbekeptawayfromtheInternet5.Parentsshouldgiveteenagerschancestomaketheirowndecisions.Teenagers_____________________________________________________.shouldbegivenchancestomaketheirowndecisions4bFillintheblankswiththe

2.Parentsshouldgiveteenagerschancestomaketheirowndecisions.父母应该给青少年自己做决定的机会。

chance(asuitabletimeorsituationwhenyouhavetheopportunitytodosth.)可数名词，意为“机会；机遇”，其后可接todosth.或ofsth.。若表示“做某事对某人来说是一次机会”，其后可接forsb.todosth.。例：Inevermissachancetoplayfootball.我从不错过踢球的机会。
