    i.NMET 单项填空中的进行时态命题
    【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。

    答案：C
    【NMET97】
    10. I first met Lisa three years ago. She _________ at aradio shop at the time.
    A. has worked B. was working
    C. had been working D. had worked
    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
    16.—Is this raincoat yours?
    —No, mine ________ there behind the door.
    A. is hanging B. has hung

    Your coat is hanging in the hall.
    ii.选项C中的一般时则表状态，表“某地挂有某物”之意，如：
    （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：

    9. Dr.Black comes from either Oxford or Cambridge, I can'tremember _________.
    A. where B. there C. which D. that
    题解：（1）该题实际上依然存在着在两者之间进行选择的意味。
    （2）将选项C代入题干，即正常表述顺序：
    I can't remember which university (or town) Dr Black comesfrom, Oxford or Cambridge.

    19.——I stayed at a hotel while in New York.
    ——Oh, did you? You with Barbara.
    A. could have stayed B. could stay
    C. would stay D. must have stayed
    题解：选项A"could have stayed"表示“原本能待在一起，但却没待”的意思，暗含责备或惊讶的意味。 此题从语法上来说，属于“混合型虚拟语气”的范畴。与第9题的命题思路一样， 出于口语化的需要，将原本 正常表述的内容，从中间断开，将后半段提到前面先说。
    请见下面的演示。
    —I stayed at a hotel while in New York.
    —You could have stayed with Barbara (if you had stayed inNew York, but in fact you stayed a t a hotel while in New York).
    类例：——I knew a little about French while in Paris.

    （2）选项A"can"表示“允许”，用在此情境中， 应为顾客所说，是上一句的继续。
    答案：B

    —Yes. I bought this radio here yesterday, but it _____.
    A.didn't work B.won't work
    C.can't work D.doesn't work
    题解：i. 'it won't work' （就是不响）应用在下面语境中：Although we've tried several times , it won't work.
    ii.'it can't work' （不可能响）→指损坏，失去效力的情形。
    'it doesn't work'（不响）→指没工作的状态，与损坏无关。

    【NMET98】
    8. I hate _________ when people talk with their mouthsfull.
    A. it B.that C.these D.them
    题解：这是it的较难的用法。it在题中指代的内容十分模糊，可以认为指某种情形，如：

    下面是it其他的较难的用法。
    （1）I take it you have been out.
    （2）Let me come and stay. You can put it that it wasarranged before.
    （3）You may depend upon it they are valuable.

    v.NMET98 单项填空中值得关注的一种命题
    23.Cleaning women in big cities usually get ________ bythe hour.
    A.pay B.paying C.paid D.to pay
    题解：（1）usually get paid=are usually paid;get=be
    （2）get paid=get their pay
    （3）由于动词get兼有行为动词与系动词两种用法，pay 兼有动词与名词两种用法，又由于pay用作名词时 ， 要与冠词或相当于冠词的词连用，使得该题答案的判断过程甚为复杂。
    答案：C
