  • 第3题：

    He demolished my argument in minutes.

    A:disproved
    B:accepted
    C:disputed
    D:supported

    答案：C
    解析：
    这句话的意思是：几分钟内他就驳倒了我的论点。句中“demolish”意为“批驳，粉碎”。 四个选项中A项意为“提出反证”;B项意为“接受”;C项意为“辩驳，质疑”;D项意为“支持”。 因此只有C项最为合适。

  • 第6题：

    He demolished my argument in minutes.

    A:disproved
    B:disputed
    C:accepted
    D:supported

    答案：A
    解析：
    本句意思：他在几分钟内就驳倒了我的观点。demolish“推翻，驳倒”。disprove是prove 的反义词，意思为“证明······是错误（虚假）的”。两词意思相近。
