    B．cannot hardly do anything

    C．can hardly do nothing

  • 第6题：

    Research indicates that over 81% of teachers are dissatisfied with their salary.

    A:shows
    B:dictates
    C:proves
    D:discovers

    答案：A
    解析：
    调查表明，超过81％的教师对他们的薪水不满意。show“表明”，如：Statistics show that sales grew a lot last month．数据显示，上个月悄售额大幅上涨。dictate“口授，命令，指挥”，例如：You can't dictate to people how they should live．你不能强行规定人们应该怎样生活。prove“证明”，例如：Can you prove it to me？你能证明给我看吗？discover“发现”，例如： Columbus discovered America．哥伦布发现了美洲。只有show意思上和indicate最接近。
