  • 第4题:

    ________ can be done ________ been done.

    A.All that...has

    B.All that...have

    C.All...has

    D.All...have


    正确答案:A
    解析:本题考查主谓一致的用法。由 all that 引导的主语从句“all that can be done”(所有能被做的事情)应视为单数,所以整个句子的谓语动词也应该用单数形式,构成现在  完成时的被动语态:has been done。句意:“所有能做的都做了。”

    The world market is__________ changing. We must anticipate the changes and make timely adjustments.

    A.stably
    B.constantly
    C.scarcely
    D.occasionally

    答案:B
    解析:
    考查副词辨析。空格处需要填入一个副词修饰“changin9”。stably“平稳地”,constantly“时常地,不断地”,scarcely“几乎不”,0ccasionally“偶尔地”。根据常识,世界市场的变化应该是随时随地的,即“经常发生变化”。故选B。?
