unwise(形容词):不明智的;欠考虑的;不聪明的决定或做法。(也可指“缺乏智慧的”,但更常用来评价某个选择/行为不妥。)
/ʌnˈwaɪz/
It would be unwise to skip breakfast every day.
每天都不吃早餐是不明智的。
It was unwise of him to trust a stranger with all his savings, especially after repeated warnings from friends.
他把全部积蓄交给一个陌生人保管是不明智的,尤其是在朋友多次提醒之后。
由否定前缀 **un-**(表示“不、非”)+ wise(明智的)构成,字面意思就是“非明智的”。这种构词方式在英语里很常见,用 un- 给形容词加上否定含义。
