"Don't do that" 是一种常见的说法，表示不要再做某种事情。这个短语可能源于人们常用的指令形式，例如 "Don't talk" 意为 "不要说话"。下面是一些例句：

"Don't do that, it's dangerous" (不要那样做，那很危险)
"Don't do that, it's rude" (不要那样做，那很不礼貌)
"Don't do that, it's against the rules" (不要那样做，那违反了规定)

另外，如果你想表达更加强烈的拒绝，你可以说 "Don't even think about it" 意为 "甚至别想"。例如：

"Don't even think about it, I'm not going to lend you any more money" (甚至别想了，我不会再借钱给你了)
"Don't even think about it, I won't forgive you for what you did" (甚至别想了，我不会原谅你的所作所为)
