The slaves were given worse food than that for their masters' dogs. (=The slaves were given food worse than that for their masters' dogs.)
比较项是worse 还是 worse food?
than分句改写补全是The slaves were given worse food than that for their masters' dogs was 吗?
句中that=the food, 我的疑问是原句可否去掉the, 而变成The slaves were given worse food than food for their masters' dogs ? 为什么呢?
