因为我还不清楚我该从哪里着手开始我的项目,所以我会感激你们的任何建议。【句式解构】(1)该句为主从复合句。as引导原因状语从句;youmayhave是省略了that/which的定语从句,修饰先行词suggestions。(2)wheretostart是“疑问词+不定式”结构,在句中作宾语。*Whenwewerewonderingwhattodo,themanagercameout.正当我们疑惑该做什么的时候,经理走了出来。*Inatrial,ajudgemustdecidewhicheyewitnessestobelieveandwhichnottobelieve.在审判中,法官必须断定哪些证人可以相信,哪些证人不能相信。*Pleasetellmewhentostarttheproject.请告诉我何时开始这个项目。【名师点津】小议“疑问词+不定式”结构(1)该结构中的常用疑问词:what,where,when,how,who,which等,该结构的作用相当于相应意义的宾语从句。(2)该结构作主语时谓语动词用单数。Whenandwheretoholdthesportsmeetingisnotknown.还不知道何时何地举行运动会。【即学活用】(1)句型转换。①Shedidn’tknowwhichbussheshouldtake.→Shedidn’tknow_______________.

只要你在使用电器设备,你便可以把它开着——如果不用就把它关掉!
