字面直译为“脱离了某人的理智/判断力”，实际表示“失去理智；发疯；昏了头”，用于形容人因情绪、压力或愚蠢行为而丧失正常的判断能力。
该短语是主系表结构，核心是描述主语的“精神/判断状态”，具体用法如下：
例：
You are out of your senses to climb that cliff!（你爬那座悬崖真是疯了！）
He must be out of his senses to spend all his savings on a fancy car.（他把所有积蓄都花在一辆豪车上，肯定是昏了头。）
常用来批评/质疑他人的愚蠢行为，或描述人因极端情绪（如悲痛、愤怒、恐惧）而失控。
例：
She was out of her senses with grief when she lost her child.（她失去孩子时，悲痛得失去了理智。）
The loud music drove me out of my senses.（ loud music 把我逼得快疯了。）
可根据语境用不同时态（现在时、过去时、将来时）：
Present: Are you out of your senses? That dog is dangerous!（你疯了吗？那只狗很危险！）
Past: He was out of his senses last night—he started arguing with a stranger for no reason.（他昨晚失去了理智——无缘无故和陌生人吵架。）
常与不定式（to do）或从句连用，说明“失去理智的具体行为”：
He's out of his senses to quit his job without a backup plan.（他没找好下家就辞职，真是昏了头。）
I think she's out of her senses if she believes that liar.（如果她相信那个骗子，我觉得她是疯了。）
be out of one's mind：与"be out of one's senses"几乎同义，更口语化（“发疯；失去理智”）。
lose one's senses：强调“从理智到失控的过程”（“丧失理智”）。
"be out of one's senses" 是口语化且常用的表达，核心是“否定某人的判断力”，适用于批评愚蠢行为或描述情绪失控的状态。记住根据主语调整所有格，搭配具体行为会更自然～
