Tobeablewritesentencesusingbythetimeorbefore.观察以下句子中主句和从句的时态特点1.过去完成时的构成:由“助动词had+动词的过去分词”构成。否定式为“hadnot+动词的过去分词”，hadnot缩写为hadn’t。2.过去完成时的含义:过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作。它表示动作发生的时间是“过去的过去”。过去完成时复习过去完成时的用法：1)表示—个动作或状态在过去某一时间或动作之前已经完成，发生在“过去的过去”。这个过去的时间可以用by，before等介词短语或者—个时间状语从句来表示。

e.g.WhenIwokeup，ithadstoppedraining.我醒来时，雨已经停了。2)表示某一动作或状态在过去某时之前已经开始，一直延续到这一过去的时间。常用表延续的时间状语如：

bytheendof+过去的时间点，bythetime+从句等。

e.g.Bytheendoflastyear,shehadworkedinthefactoryfortwentyyears.到去年年底，她已经在这家工厂工作20年了。【中考链接】1.Theplane_______whenwegottotheairport.A.hadtakenoffB.wastakenoffC.willtakeoff2.BythetimeIgottothemeetingroom,Mr.Li___hisreport.A.finishesB.hasfinishedC.hadfinished3.WhenIgottothebusstop,thebus______already______.
