  關于完成時態(tài)的注意點
  <例句>
  I won't believe you until I've seen you in the room with my own eyes.
  我要親眼見到你在這個屋子里才相信你。
  <語法分析>
  在時間和條件狀語從句中,可用現在完成時態(tài)代替將來完成時。延續(xù)性動詞可用于現在完成時,可接表示段的時間狀語。非延續(xù)性動詞也可用于現在完成時,但不接表示段的時間狀語。有時在口語中,可用一般過去時代替現在完成時。有些動詞,如hope, plan, mean, expect和think等有時可用過去完成時來表示一個本來打算做而未做,曾經設想而未實現的事情。在時間和條件狀語從句中,過去完成時可代替過去將來完成時。
  <觸類旁通>
  (1) He has got constant help from her since he has known her.
  自從他認識她以來,他一直得到她的幫助。
  語法分析:為了強調從句謂語動詞從過去某一時刻開始,一直延續(xù)到現在,可用現在完成時態(tài)。
  (2) I have never heard of her since she left.
  自她離開后湖,我從未聽說過她。
  語法分析:since從句如果用現在完成時,其謂語動詞一定是延續(xù)性的,如果是非延續(xù)性的,則只能用一般過去時。
  (3) The vistors have stayed here for three days.
  來訪者在這兒住了三天。
  語法分析:延續(xù)性動詞可用于現在完成時,可接表示段的時間狀語。
  (4) The young man has joined the Party.
  這年輕人入了黨。
  語法分析:非延續(xù)性動詞也可用于現在完成時,但不接表示段的時間狀語。
  (5) I had intended to come over to see you, but was prevented from doing so.
  我本打算來看望你,但受阻沒有來成。
  語法分析:用過去完成時來表示一個本來打算做而未做,曾經設想而未實現的事情。
  (6) We would get into trouble as soon as the water had run out.
  水一用完,我們就會陷入困境。
  語法分析:在時間和條件狀語從句中,過去完成時可代替過去將來完成時。
