常见错误

❌ 错误:I have an unexcused reason for being late.
✓ 正确:I have no excuse for being late, so it's unexcused.

错误在于逻辑矛盾:'unexcused' 表示没有理由,不能与 'reason' 搭配。正确用法是强调缺乏借口,直接说明迟到是无故的。

❌ 错误:He was unexcused to leave early.
✓ 正确:He left early without permission, so it was unexcused.

错误在于语法结构:'unexcused' 是形容词,通常修饰名词如 'absence',而不是直接接动词不定式。正确用法是用它描述行为的状态。

近义词辨析

unauthorized

'unauthorized' 更强调缺乏正式许可或批准,常用于法律、安全语境;'unexcused' 更侧重缺乏合理理由或借口,多用于缺席、迟到等行为。

Unauthorized access to the system is prohibited (强调许可),while unexcused absence from class is penalized (强调理由)。

unjustified

'unjustified' 表示没有正当理由或依据,可用于更广泛的批评或判断;'unexcused' 特指在规则或纪律框架下缺乏可接受的解释。

His anger was unjustified (没有依据),but his absence was unexcused (违反规则)。
