易错句子Many people railed the new tax.
正确表达Many people railed against the new tax.
rail 表示“强烈抱怨、斥责”时是不及物动词，必须用介词 against 或 about 引出抱怨的对象，不能像汉语“抱怨某事”那样直接跟宾语；所以要加 against。

易错句子Customers railed on the poor service.
正确表达Customers railed about the poor service.
rail 表达“抱怨”时，引出对象只用 against 或 about，不用 on；汉语“对……抱怨”中的“对”容易误导学习者写成 on，此处应改为 about。
