常见错误

❌ 错误:I use diphenhydramine for cure my cold.
✓ 正确:I use diphenhydramine to relieve my cold symptoms.

错误在于'cure'(治愈)用法不当,苯海拉明通常缓解症状而非治愈疾病;应改为'relieve symptoms'(缓解症状)。

❌ 错误:Diphenhydramine is a good medicine for everyone.
✓ 正确:Diphenhydramine may not be suitable for everyone, such as pregnant women.

错误在于过度泛化,苯海拉明并非对所有人都安全;应添加限制条件,如'not suitable for everyone'(并非适合所有人)。
