问:When was John's appointment with the doctor?

问题描述:

问:When was John's appointment with the doctor?
为什么要用John‘s?
回答是:His appointment was at 11 a.m
想问的是为什么appointment 前面都用了代词所有格?

因为这句中的appointment是名词形式,所以前面用名词所有格或物主代词,这句话的意思是约翰和医生预约在几点?其实这句话也可以用动词来表达,即
When did John make a appointment with the doctor?
