USAGE NOTE 用法说明: disinterested and 和 uninterested
People sometimes use disinterested to mean 'not interested in something', although it really means that someone is not personally involved in a situation so they can judge it fairly. 有时人们会把 disinterested 用作对某事不感兴趣的意思，但该词的实际意思是某人不卷入某种事情中，因而能够对它做出公正的评判:
a group of disinterested investigators 一批公正无私的调查员。
If you want to say that someone is not interested in something, use uninterested. 如果你想说某人对某事不感兴趣，可用 uninterested:
She seemed totally uninterested in what we had to say. 她对我们要说的话似乎丝毫不感兴趣。
