感觉有人不正常，可能要发疯，英文你只会用crazy或mad?那么你知道发疯还有哪些英语说法吗?下面来学习一下吧。
发疯的英语说法：
1. Funny farm
Funny farm不是“有趣的农场”，它专指“精神病院”，是种没礼貌的说法。所以,如果你对别人讲：“Do you belong in a funny farm? (你有病啊?)”小心挨揍哦!
2. Not all there
虽然人在你面前，但神志似乎不全在这里~ 英文用not all there形容人不清醒，做事不精明。例如：You can’t depend on Paul for much help. He’s really not all there.(你别指望保罗能多帮忙。他这人糊涂着呢。)
3. Not in one's right mind
人总有不在状态的时候，但要是脑子没在正常的波段里活动，就真的不正常了…… Not in one's right mind意思正是“精神失常”，例如：There's something wrong with him. He's not in his right mind. (他有点儿不对劲，神经不正常了。)
4. Mentally unstable
有一种不稳定是情绪的，还有一种不稳定是精神的。“情绪不稳定”英文可以说emotionally unstable。但如果说: She is mentally unstable.就是要疯了。
5. Lose one's marbles
Marble本身有“大理石”、“弹珠”的意思，但其复数形式marbles还可以指人的心智。所以，lose one's marbles就可以理解为失了心智，发疯。例：He's losing his marbles.(他这是疯了。)
