常见误用提醒
使用 appeal：He appealed the judge for mercy. → He appealed to the judge for mercy. (错误：appeal 作为动词表示呼吁时，应接介词 to 引出对象，不能直接接名词。正确用法是 appeal to someone for something。)
使用 appeal：The product has a strong appeal for me. → The product has a strong appeal to me. (错误：表示吸引力时，appeal 作为名词常与介词 to 连用，而不是 for。正确用法是 appeal to someone，表示对某人有吸引力。)
使用 plead：I plead him to help me. → I pleaded with him to help me. (错误在于缺少介词 with；plead 作恳求时，常用 plead with someone to do something 结构，表示向某人恳求。)
