常见错误

❌ 错误:We need to redouble on our work.
✓ 正确:We need to redouble our efforts at work.

错误在于误用介词 on,redouble 通常直接接宾语如 efforts,表示加强努力,而不是用 on 连接。应改为 redouble our efforts 或类似结构。

❌ 错误:He redoubled to study harder.
✓ 正确:He redoubled his efforts to study harder.

错误在于 redouble 后直接接不定式 to study,这不符合英语习惯。redouble 是及物动词,需接名词宾语,如 efforts 或 focus,然后可用不定式表示目的。
