  • 第2题:

    It is out of the question that the inspector will come tomorrow.

    A:impossible
    B:possible
    C:probable
    D:likely

    答案:A
    解析:
    利用选项的特点:选项A和B是一对反义词,所以重点注意。而选项B、C和D都是近义词,表示“可能的”,所以排除掉。答案是A项。该句句意是:检察员明天不可能来。out of the question表示“不可能”;另外,likely也可作副词,表示“或许、很可能”。

  • 第3题:

    Some states have an income tax ______ tothat of the federal government.

    A.same
    B.similar
    C.alike
    D.likely

    答案:B
    解析:
    考查形容词辨析。句意为“一些州有与联邦政府类似的所得税”。代词that指an income tax。Similar to“与……类似的”,形容词短语作后置定语,相当于定语从句which is similar to that of the federal government。same意为“同样,一样”,likely to意为“可能的”,均与句意不符。alike为表语形容词,只作表语。故选B。
