I want a wife who will plan the menus, do the necessary grocery shopping, prepare the meals, serve them pleasantly, and then do the cleaning up while I do my studying.

—— them 指 the meals，意思是 “愉快地端饭上菜”。

I want a wife who will care for me when I am sick and sympathize with my pain and loss of time from school.

—— school 之前是零冠词，是抽象意义，意味着“学业”，不是指学校。time from school 指 “来自学业的时间”，from 指“来源”。其实“来自”二字，不需要翻译出来。直接说“学习上的时间”。
