难得有人读新概念正文之前的东西...
实际上，我觉得新概念英语所倡导的教学法可能只对拉丁语系各语种的使用者有效，对汉语使用者来说不适用，因为语言面貌相差太远了。

这个时候，你要去urban dictionary。各种俗语在这里都能查到解释，我来给你粘贴下吧：
adjective. The definition of die hard is someone or something that shows or possesses extreme, absolute or complete loyalty even if facing defeat or hopelessness. An example of a die hard fan is a person who goes to see a losing team play every single game, even in the rain or if the game is a practice game.

不应该是虎胆龙威吗
