  肯定回答:Yes,主語(yǔ)+had

  否定回答:No,主語(yǔ)+hadn't

  ④特殊疑問(wèn)句:特殊疑問(wèn)詞+一般疑問(wèn)句(had+主語(yǔ)+過(guò)去分詞+其他)

  語(yǔ)法判定:

  ( 1 ) by + 過(guò)去的時(shí)間點(diǎn)。如:

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

  ( 2 ) by the end of + 過(guò)去的時(shí)間點(diǎn)。如:

  We had learnt over two thousand English words by the end of last term.

  ( 3 ) before + 過(guò)去的時(shí)間點(diǎn)。如:

  They had planted six hundred trees before last Wednesday.

將來(lái)完成時(shí)

  (shall)will+have+動(dòng)詞過(guò)去分詞

  before+將來(lái)時(shí)間或by+將來(lái)時(shí)間

  before或by the time引導(dǎo)的現(xiàn)在時(shí)的從句

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

過(guò)去將來(lái)完成時(shí)

  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(jìn)行時(shí)

  基本與現(xiàn)在完成時(shí)相同,但是現(xiàn)在完成進(jìn)行時(shí)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(guò)去完成進(jìn)行時(shí)

  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.
