過去完成時
過去完成時是一個相對時態(tài),表示過去的過去,只有在兩個過去發(fā)生的動作相比較時才可顯示出來。
例:As soon as we got to the station, the train had left.
注:主從句表達(dá)的動作緊接時,即兩動作發(fā)生的時間沒有明顯時間上的懸殊或空檔時,主從句都可用一般過去時。

  例: How are you feeling today?

  你今天感覺怎樣?(顯得親切)

  You are always boasting.

  你老愛吹牛。(厭煩)

  now, these days, recently, this week 等。
