常见错误

❌ 错误:The room is very sterile, so it's clean.
✓ 正确:The room is very sterile, meaning it's free from germs.

sterile 强调无菌或消毒状态,而 clean 仅指干净;在医学或科学语境中,sterile 更精确,应避免混用。

❌ 错误:He is sterile because he can't have children.
✓ 正确:He is infertile because he can't have children.

sterile 可指不孕,但 infertile 更常用且具体指生育能力问题;sterile 在医学中更常指无菌,使用时要根据语境选择。
