两天以后怎么说?是不是in two days after two days

用's 来修饰这个时间time,你可以说in two days.
下面是国外语法的解释,希望对你又帮助.
Use apostrophes in phrases such as in two days' time,12 years' imprisonment and six weeks' holiday,where the time period (two days) modifies a noun (time),but not in nine months pregnant or three weeks old,where the time period is adverbial (modifying an adjective such as pregnant or old)

我觉得他加time 是有原因的.汉语为在两天的时间里.这里表示段时间 相当于 during two days
in two days 之表示一个将来的时间.可能是说话人口语 说的很随便.差异不大.
