(Yes,主语＋had./No,主语＋hadn’t.)特殊疑问句：疑问词＋had＋主语＋过去分词＋…？二、过去完成时的判断依据:由时间状语来判定：表示动作从过去持续到过去一段时间。与过去完成时连用的时间状语有：(1)by+过去的时间点。Ihadfinishedreadingthenovelbynineo'clocklastnight.昨天晚上九点前我已经读完这本小说了。(2)bytheendof+

过去完成时表示“过去的过去”，是指过去某一动作之前已经发生或完成的动作，即动作有先后关系，动作在前的用过去完成时，在后的用一般过去时。这种用法常出现在：宾语从句中:当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去完成时。在told,said,knew,heard,thought等动词后的宾语从句。She

said

thatshe

hadseen

thefilm

before.她说她以前看过这电影。(2)状语从句中:在时间、条件、原因、方式等状语从句中，主、从句的动作发生有先后关系，动作在前的，要用过去完成时，动作在后的要用一般过去时。WhenIgottothestation,thetrainhadalreadyleft.当我到达车站时，火车已经离开了。Afterhehadfinished
