    in 100 years 在100年后
    in+时间段,表示“在……之后”。
    【辨析】in与after
    “in+时间段”是指以现在时间为起点的“在一段时间以后”,用在一般将来时态的句子中,对其提问how soon。
    “after+时间段” 也表示“在(时间)之后”,常用在一般过去时态的句子中;常常指以过去时间为起点的“在一段时间之后”。after后面接时间点时,与一般将来时连用。如:
    He will come back in ten days.他将在十天后回来。
    He came back after ten days. 他十天后回来了。情景导入 生成问题
