fromthepresentperfecttothepastperfecttense.HowardCartersaid,“IhavestayedinEgyptformorethan30years,searchingforthetombsoftheEgyptiankings.”过去完成时与现在完成时的区别现在完成时表示的是延续到现在或与现在有关的动作过去完成时表示的是在过去某时之前已经完成或延续到过去某时的动作（句中有表示过去特定时间的状语)比较下面两个句子：Shehadbeenillforaweekbeforeshecameback.Shehasbeenillforaweek.生病发生在“过去的过去”现在仍在生病现在完成时着眼于现在，强调过去发生的某动作对现在造成的影响和结果，或是由过去持续到现在的动作。

Ihavecleanedtheclassroom.我打扫干净教室了。（强调扫地所产生的结果：地干净了。）

Theyhavelivedherefortwentyyears.他们住在这二十年了。（“住”从过去持续到现在的动作用现在完成时。）过去完成时则主要体现过去发生的两动作的先后有别，表达的是“过去的过去”，即比过去发生的某动作都还要“过去”，两动作中先发生的就用过去完成时，后发生的则只用一般过去时。运用过去完成时的句子往往有过去的时间或动作。e.g.(1)MrSmithhadlivedinLondonfortenyearsbeforehecametoChina.史密斯先生在来中国之前就已经在伦敦住过十年了。（“来”中国已成过去，而先前“住”在纽约就是过去的过去。）(2)Wehadlearned600wordsbytheendoflastyear.到去年，我们已经学了600个单词。（“去年”已过去，而在之前“学”的就更过去了。）
