fooling

易错句子It was a fooling decision to lend him the money.

正确表达It was a foolish decision to lend him the money.

fooling 作形容词表示“玩闹的、不负责任的”，并不表示“愚蠢的”；评价某个决定“傻”要用形容词 foolish，所以修饰 decision 时应换成 foolish。

易错句子Don't be such a fooling; take it seriously.

正确表达Don't be such a fool; take it seriously.

such a 后面必须接可数名词，而 fooling 是形容词（也可看作动词 fool 的 -ing 形式），不能充当名词；表示“傻瓜”要用名词 fool。
