解释一句VOA的含义
第一句不用解释,第二句才需要解释.
At times,he was a good commander and a brave man.At other times,he stay in the safety of the cities,instead of leading his men to fight.
"stay in the safety of the cities”,这里意思是“呆在安全的城市”,还是“呆在城里面的安全地方”,为什么不写成“stay in the safe city”?句子的意思和这个一样吗?

意思是“呆在城里面的安全地方”,这是表示一种状态,强调的是safety,不能写成“stay in the safe city”,这里强调的是城市,safe做city的形容词,二者强调的内容不一样.
