易错句子His anger vented on his family after work.
正确表达He vented his anger on his family after work.
vent 表示「发泄（情绪）」时是及物动词，主语必须是人，被发泄的情绪只能作宾语。汉语可以说「他的怒气发泄在家人身上」，把情绪当成主语直译过来就成了 His anger vented，英语里不成立。应改成人作主语、情绪作宾语：He vented his anger...

易错句子He often vents his anger with his wife.
正确表达He often vents his anger on his wife.
表示「把怒气发泄到某人身上（迁怒）」时，英语固定搭配是 vent sth on sb，介词用 on。汉语「跟/和某人生气、发脾气」里的「跟、和」若直译成 with，会被理解为「和妻子一起发泄」或「拿妻子当工具」，与想表达的迁怒意思不符，所以要把 with 换成 on。
“emit”中性、正式，多指机器或物体发出光、热、气体、声音，不用于情绪；要表达“发泄情绪”只能用 vent，如 vent one's anger。
“express”是中性“表达”，正面或负面情绪都可以，重在让别人知道；“vent”则强调把积压的强烈情绪（尤其愤怒、不满）发泄出来。
“release”适用范围更广，可指释放气体、压力、人或公开信息，语气中性；“vent”侧重通过开口把气体排出，或宣泄情绪，常与 anger、frustration 搭配。
