no more . . . than 易于；倾向于

A:But experts say the famous are no more prone to breakups than anyone else.
A:不过专家们说这些名人不见得会比一般人更容易分手。

no more prone to . . . than . . . 中的 no more . . . than 为否定比较。prone to 意思与 tend to 同，表「易于；倾向于」，也可说成 more likely to . . . 。因此，本句的意思就是「不会比……更容易……」。 例句：

B: A single man is no more prone to be in an automobile accident than a married man.
B: 单身汉不见得比已婚男子开车更容易肇事。
