      現(xiàn)在完成時是英文時態(tài)的一種。
      現(xiàn)在完成時的用法:
      主語+have(has)+過去分詞(done);
      現(xiàn)在完成時用來表示現(xiàn)在之前已發(fā)生過或完成的動作或狀態(tài),但其結果卻和現(xiàn)在有聯(lián)系,也就是說,動作或狀態(tài)發(fā)生在過去但它的影響現(xiàn)在還存在。

      擴展資料

        現(xiàn)在完成時可以用來表示發(fā)生在過去某一時刻的,持續(xù)到現(xiàn)在的情況,常與for,since連用.

        Mary has been ill for three days.

        I have lived here since 1998.

        現(xiàn)在完成時往往同表示不確定的過去時間狀語連用,如already, yet, just, before, recently,still, lately等:

        He has already obtained a scholarship.

        I haven't seen much of him recently (lately).

        We have seen that film before.

        Have they found the missing child yet
