英语翻译
第一:Mr Harris lived in a small house by himself.第二:The doctor read it and then said ,“But people don't know when they have this illness!and they feel just well.”That's just what I feel.(另外这里的 by,如何译?)劳驾!

by oneself是固定用法,单独,独自.by是介词,在旁边的意思.自己在自己旁边,当然就是一个人了.
when这里是引导宾语从句的疑问副词.人们不知道他们“何时”得病.自我感觉还挺好.
