Tom ’s uncle is going on busines——.

Tom 's uncle is going on busines——.
A,after a few day's time
B,in a few days'
C a few day's time later
D,in a few day's time

B
在将来时中表示“多少时间以后”用in + 表示时间的名词,因此A/C不对（after/later用于过去时中表示什么时间以后）
第二,in+时间,有两种表达法：in ten days或者in ten days' time,10天是复数,复数的所有格要变成s'再加time,据此D错在,应该是：in a few days' time
再问： 不好意思，我刚刚打错题目了应该是 Tom 's uncle is going on busines——。 A，after a few day's time B,in a few days' C a few day's time later D,in a few days' time
再答： 那是D对的，B应该是：in a few days（后面不要'，因为'表示所有格，后面要跟个名词，没有名词就不需要用所有格了）
