he did it this moring 为什么this morning不用加介词in
请问下为什么有一些句子中一些时间都不用加上介词on或in的 比如说yesterday evening ,this morning..
请说下其中的知识点
he did it this moring 为什么this morning不用加介词in
表示时间介词at, on, in 的省略
(1) 在 next, last, this, these, today, yesterday, tomorrow, one, every, each, all等词前,一般不用 at, in, on.
(2) 在某些名词词组前,可以省略(也可不省)如: (on) that day, (in)the year before last常见搭配1．动词+介词,如：listen to, laugh at, write to, hear from, get to, look at, shout at, shout to, knock at,……
PS：morning, afternoon, evening这些词语的前面如果有this,that等指示代词修饰时,就不能再用介词了
he did it this moring 为什么this morning不用加介词in 为什么He did it this morning 这里的时间状语一定要this morning 而不能说this是定语 where did you meet him this morning?it was in the hotel ＿he 为什么 this afternoon不用加介词,而 in the afternoon要加? .this morning 前面要不要加介词,比如on in in summer holiday与this summer holiday的区别或者用法,为什么有的时候不用加介词? He did some reading this moring(改为否定句） did mother look 【介词】this key this morning He did it this morning 时间状语可以说只是morning吗因为this 是修饰morning的 Why did he cut himself this morning? --He didn't go to school this morning,did he? He (get) up early this morning,did not he?
