（2） by the end of + 過去的時間點。如：
We had learnt over two thousand English words by the end of last term.
（3） before + 過去的時間點。如：
They had planted six hundred trees before last Wednesday.
(3)將來完成時
（shall）will+have+動詞過去分詞
before+將來時間或by+將來時間
before或by the time引導的現在時的從句
He will have worked for us.=He will work for us.
(4)過去將來完成時
should / would have done sth.
He said that he would have worked for us.=He said that he would work for us.
(5)現在完成進行時
基本與現在完成時相同，但是現在完成進行時只能表示仍然持續的概念
have/has been +-ing 分詞
He has been working for us for ten years.=He has worked for us for ten years.
(6)過去完成進行時
had been +-ing 分詞
He said that he had been working for us for ten years.=He said that he had worked for us for ten years.
(7)將來完成進行時
主語+ shall/will have been doing
He will have been working for us.=He will work for us.
翻譯爲：他最近一直在爲我們工作（過去在工作，現在在工作，將來還會工作）
(8)過去將來完成進行時
should+have been+現在分詞用於第一人稱
would have been+現在分詞用於其他人稱
He said that he would have been working for us.=He said that he would work for us.
