It is better to spend money on preventing illnesses by promoting healthy living rather than spending it trying to make people better after they are ill.
为什么rather than 后面要用动词的ing形式spending?它前面不是to do么?
preventing illnesses by promoting healthy living 和spending it trying to make people better 是并列的,
前边是preventing后边就用spending
