常见错误

❌ 错误:This drug is very excitatory for patients.
✓ 正确:This drug has an excitatory effect on patients.

错误在于直接使用 'excitatory for',这不符合英语习惯。正确用法是 'have an excitatory effect on',因为 excitatory 通常描述作用或特性,而不是直接修饰人。

❌ 错误:He felt excitatory after drinking coffee.
✓ 正确:He felt excited after drinking coffee.

错误在于混淆了形容词 excitatory 和 excited。excitatory 描述事物具有兴奋作用,而 excited 描述人的感受。这里应使用 excited 来表示个人情绪。
