  • 第5题：

    [A] acquire

    [B] achieve

    [C] obtain

    [D] fulfill


    正确答案：B
    34. B

  • 第6题：

    His clients often defer payment for as long as possible.

    A:make
    B:demand
    C:postpone
    D:obtain

    答案：C
    解析：
    本题考查的是对动词的认知。这句话的意思是：他的客户经常尽可能地推迟支付时间。defer的意思是推迟，例如：We wish to defer our decision until next week．我们希望推迟到下星期再作出决定。A.make做；B.demand要求；C.postpone推迟，例如：It won't hurt to postpone the matter for a few days．此事耽搁几天无碍；D.obtain获得。defer和postpone意思最接近，所以选C。
