During the Ming and Qing dynasties, the emperors and their families (family) worked and lived in the Forbidden City.
参考译文:在明清时期/朝代,皇帝和他们的家庭(家族)都在紫禁城工作和生活。
备注:明清朝代的皇帝是有多个皇帝,多个皇帝就会有多个家庭。所以用复数。而且表示家族也可以用复数。
There are fifties families in the village.在这个村庄有五十个家庭。
Some families have farmed in this area for hundreds of years.
有些家族在这个地区务农有几百年了。
