    【NMET98】
    20.Shirley________a book about China last year but I don'tknow whether she has finished it.
    A. has written B. wrote
    C. had written D. was writing
    题解：进行时可表一时的动作，而不表动作的结束。若选用B， 意思则是“去年Shirley写了一部有关中国 的书。 ”这样一来就与题干的后半部分所交待的事实发生矛盾。
    答案：D
    24.——Hi, Tracy, you look tired.
    ——I am tired. I ____________ the living room all day.
    A. painted B. had painted
    C. have been painting D. have painted
    题解：（1）题干中的"all day"有强调作用，使用现在完成进行时与之配合使用。
    （2）观察下面句子中现在完成进行时的用法。
    They have been meeting together weekly now for two years.
    答案：C
    【NMET97】
    10. I first met Lisa three years ago. She _________ at aradio shop at the time.

    题解：题干中的'at the time=three years ago'， 与过去时态连用；选用过去进行时暗含‘暂时’之意 。选项C、D均用于过去的过去，与题意不符，故不用。
    答案：B

    （1）The picture hangs now in my library.
    （2）Above it hung an oil painting by Beryl.
    iii. 选项B中的完成时应使用其被动语态形式：has been hung，而且句子主语也要变化，如：
