常见错误

❌ 错误:This job is very laborious for me to do.

错误:laborious 本身已包含“费劲”之意,无需再加 for me to do,这会使句子冗余。正确:直接使用 laborious 描述任务性质即可。

❌ 错误:He is a laborious worker, always finishing tasks quickly.
✓ 正确:He is a diligent worker, always finishing tasks quickly.

错误:laborious 形容任务或过程艰苦,不直接形容人“快速”完成工作;它可形容人勤劳,但更强调付出努力而非效率。正确:用 diligent 表示勤勉且高效。
