时态3---
过去进行时构成：was/weredoing
典型时间状语：atsevenlastnight,atthattime,atthatmoment,allthetime,when,whileIwasn’tnoticing.Iwasthinkingofhome.
过去将来时构成：woulddo
Iknewhewouldhelpme.(Iknowhewillhelpme.)
过去完成时构成：haddone
在by、bytheend、bythetime、until、before、since、than后接表示过去某一时间的短语或从句以前发生的动作。
Bytheendoflastyear,wehadproduced20,000cars.
表示本来希望实现的希望、打算、意图、诺言等。常用hadhoped/planned/meant/intended/thought/wanted/expected等。
Ihadhopedtobebacklastnight,butIdidn’tcatchthetrain.
“一……就”的几个句型中：hardly…when/nosooner…than/scarcely…whenNosoonerhadwebeenseatedthanthebusstarted.
一般过去时和过去完成时的区别
“时间名词+before”在句子中作状语，谓语动词用过去完成时；“时间名词+ago”在句中作状语，谓语动词用一般过去式。如：Hesaidhisfirstteacherhaddiedatleast10yearsbefore.
在before或after引导的时间状语从句中用一般过去时态代替过去完成时。
Afterhe(had)lefttheroom,thebosscamein.
时态的一致性：宾语从句
