ound，taste，look。五、过去完成时考点分析1．常用过去完成时的几种情况：（1）在by，bytheendof，bythetime，until，before，since后接表示过去某一时间的短语或从句以前发生的动作。如：Bytheendoflastyear，wehadproduced20000cars.Thetrainhadleftbeforewereachedthestation.（2）表示曾实现的希望、打算、意图、诺言等，常用hadhoped/planned/meant/intended/thought/wanted/expected等表示，或用上述动词过去式接不定式完成式表示，即：“hoped/planned...＋tohavedone”。（3）“时间名词＋before”在句子中作状语，句子用过去完成时；“时间名词＋ago”在句中作状语，句子用一般过去式。如：Hesaidhisfirstteacherhad_diedatleast10_years_before.XiaoHualeftschool3_years_ago.（4
