1. 用作动词，两者都可表示“治疗”，但它们表达的意思有区别：cure 通常强调结果，指治愈某种疾病或某人的疾病；而 treat 则通常强调过程，指对病人进行诊断和治疗，但不含治好的意思。比较：

A few days’ rest will cure you.

This medicine will cure your cough.

The dentist is treating my teeth.

Is he able to treat this disease (the wound)?

2. 注意以下两句 cure 和 treat 所搭配的介词不同：

The doctors cured her of cancer.

Which doctor is treating you for your illness?

有时用于引申义。如：

Parents try to cure their children of bad habits.

3. cure 表示“治疗”，可用作名词。若表示“对……的治疗”或“治疗……的方法”，一般用介词 for。如：

Is there a certain cure for cancer yet?

Scientists have so far failed to provide a cure for the common cold.
