hollow

empty, vacant, hollow

这一组词都表示“空的”，但涵义有所不同。
empty: 意思是“里面没有东西”、“一无所有”，具有“空无一物”的隐含意义，它可以用来描绘box、vessel、cupboard、bag、purse、room、house、street、stomach、head 等词。

hollow: 意思是“空心的”、“中空的”、“空洞的”、“下陷的”，它常与tree、ball、cheeks、voice、sound、words、promise等词连用，由此可见，它既可用以指实物的“中空”，亦可指 words、promise、compliments的“虚假”，用于后者场合是比喻意义。
