求正确翻译She reads after lunch .非常感谢

她午餐后读书.He reads before he sleeps .
He drinks coffee before he works .
请问一下这两句的翻译呢 不甚感激~不客气。

他在睡觉前读书。
他在工作前喝咖啡。请问一下为什么后两句后面要加一个he呢before 后面直接跟动词的话要用ing形式。
he reads before he sleeps = he reads before sleeping.
he drinks coffee before he works = he drinks coffee before working.
