一、部分否定
    
    常用詞有代詞或副詞：all、both、every、everybody、every day、everyone、many、everything、entirely、altogether、absolutely、wholly、completely、weathered、always、often等和not搭配時，表示部分否定，意為“并非都是，不是每個都是”。
    
    Both of them are not my brothers.

    a.否定主語，但否定詞not在形式上往往否定謂語。

    d.在not…and 結(jié)構(gòu)中，否定的往往是and 后的部分，但否定詞not往往否定謂語。
