  肯定回答:Yes,主語+had

  否定回答:No,主語+hadn't

 ?、芴厥庖蓡柧洌禾厥庖蓡栐~+一般疑問句(had+主語+過去分詞+其他)

  語法判定:

 ?。?1 ) by + 過去的時間點。如:

  I had finished reading the novel by nine o'clock last night.

 ?。?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.

將來完成時

 ?。╯hall)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(dǎo)的現(xiàn)在時的從句

  He will have worked for us.=He will work for us.

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.

現(xiàn)在完成進行時

  基本與現(xiàn)在完成時相同,但是現(xiàn)在完成進行時只能表示仍然持續(xù)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.

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.

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.
