    have doing sth是現(xiàn)在完成時進行時態(tài),F(xiàn)在完成進行時,是英語中動詞的一種基本時態(tài),其構(gòu)成為:主語+助動詞(have/has)+been+動詞的現(xiàn)在分詞+其他成分。表示動作從某一時間開始,一直持續(xù)到現(xiàn)在,或者剛剛終止,或者可能仍然要繼續(xù)下去。

    擴展資料

      現(xiàn)在完成進行時基本句型:

      肯定式第一人稱have been doing sth.

      疑問式:Have+第一人稱+been doing sth.

      簡略回答:Yes,第一人稱 have.No,第一人稱 haven't.

      肯定式:第三人稱+has been doing sth.

      疑問式:Has+第三人稱been doing sth.

      簡略回答:Yes,第三人稱has.No,第三人稱hasn't.

      1)表示一個在過去開始而在最近剛剛結(jié)束的行動,如:

      Ann is very tired. She has been working hard.

      Why are your clothes so dirty? What have you been doing?

      2)表示一個從過去開始但仍在進行的行動,如:

      It has been raining for two hours.(現(xiàn)在還在下)

      Jack has been feeling very well recently.

      3)表示一個從過去開始延續(xù)到現(xiàn)在,可以包括現(xiàn)在在內(nèi)的一個階段內(nèi),重復(fù)發(fā)生的行動,如:

      She has been playing tennis since she was eight.

      4)現(xiàn)在完成時強調(diào)動作行為的結(jié)果、影響,而現(xiàn)在完成進行時只強調(diào)動作行為本身,如:

      Tom’s hands are very dirty. He has been repairing the car.

      The car is going again now. Tom has repaired it.

      標(biāo)志:1.句中常有延續(xù)性動詞,2.時間點前有since。
