Wu Yifan was busy last Sunday.He visited his grandmorther Saturday morning.
时间前面怎么没有介词on呢?怎么回事呢?
我是问的第二句话的哦

像last Sunday,this Saturday,next Sunday,this morning,tomorrow,yesterday,last night,yesterday evening 等时间状语前面都不用加介词,这是固定用法,即：星期名称前如有last,this,next等词,省略介词.
翻译：上星期天吴一凡很忙,他星期六上午去拜访了他的奶奶.
有不明白的请继续追问,
再问：我问的是Sunday moring 前怎么没有介词呢？
再答：你句子中写的是Saturday morning，也不是Sunday morning呀。这个Saturday morning前面应该加介词on，因为是在某个星期几的早晨，具体某一天的早晨前面用介词on，所以我想，你可能打错了，马虎了吧，从你追问成Sunday morning来看，你应该爱马虎，呵呵
