  • 第6题:

    The path in the park looked beautiful,( )with( )leaves.

    A.covered;falling
    B.covered;fallen
    C.covering;falling
    D.covering;fallen

    答案:B
    解析:
    考查非谓语动词。动词cover的逻辑主语为The path,二者为动宾关系,即The path is covered with ...故第一个空填covered,排除C、D两项。falling 表主动、进行或原因、条件等,fallen 表被动或完成状态。通过分析可知,覆盖在小路上的应为“已经掉落的叶子”,故fallen更符合句意。故本题选B。句意:公园里的小路看起来很漂亮,满是落叶。
