They will come back（in）two days.为什么不用after?
（In）about three days.（回答）为什么用in?我记得有一个回答好像用for的,什么时候用for啊?
They will come back（in）two days
in 加段时间,表示从现在起一段时间之后,常与将来时连用
after加段时间,要结合上下文使用,与过去式连用较多
for加段时间表示段时间,表示动作持续的时间,动词必须是延续系动词,常与现在完成时连用,
希望对你有帮助,满意请采纳
in+时间 ....时间以后 （用于将来时）
after+时间 ...时间.以后（用于过去时）
for+时间 （一段时间）for two days 两天了
您好！很高兴为你解答！
因为in+时间段 表示将来的动作
翻译：他们2天后将会回来
