    2 、談到過去的情況時

    與這個時態(tài)連用的時間狀語常有:

    when, after, as soon as 引導的時間狀語從句,表示主句動作開始的時間。

    1 、表示經(jīng)常性或習慣性動作。
    e.g. It seldom snows here.
    2 、表示現(xiàn)在的特征或狀態(tài)。
    e.g. He is always ready to help others.
    3 、普遍真理。
    e.g. Action speaks louder than words.
    4 、劇情圖片介紹,背景說明,動作解說。
    e.g. (Tom enters the room_and_sits at the table)
    Doctor : What`s your trouble, young man?
    Tom : I`ve caught a cold, doctor.
    5 、時間、條件、讓步、方式狀語從句表將要發(fā)生的動作時。
    e.g. Tomorrow we shall go for an outing unless it rains.
    與這種時態(tài)連用的時間狀語常有:
    always, often, never, seldom, usually, once, a week, now 等。
    篇三:一般過去時現(xiàn)在完成時
    一般過去時現(xiàn)在完成時主要用于:
    1 、表示到現(xiàn)在為止這一時期中發(fā)生的動作或情況,即多次動作的總和。
    e.g. We have learnt four English songs this month.
    How many times have you read the novel?
    For many days we haven`t seen each other.
    2 、表示對現(xiàn)在有影響的某一已發(fā)生的動作。
    e.g. The delegation has left 代表團已經(jīng)走了(說明現(xiàn)在不在這里)
    Look, what you have done. 看你干的事。
    與這一時態(tài)連用的時間狀語有:
    already, yet, just, ever, never, by now, so far, recently, by the end of this month, since, for 短語,連詞 since 引導的時間狀語從句。
    一般過去時與現(xiàn)在完成時的區(qū)別:
    一般過去時:重在說明動作在過去發(fā)生時的具體情況(時間、地點、方式、對象、細節(jié)等)。
    現(xiàn)在完成時:只提起已發(fā)生的動作(事實)及其影響,不說明動作發(fā)生時的具體情況。
    cf. Have you had your lunch?
    What did you have for lunch?
    I have ever been to the Great Wall,_and_I went there last summer with my father.
    注:現(xiàn)在完成時表達的動作常具有反復性,故下面一句是錯的:
    Have you seen the six thirty`s news program?
    應改為:
    Did you see the six thirty`s news program?
