问题描述:

My family are very happy------
A.on that day
B.that day.
哪个对呢

B is right

应该是:my family were very happy that day.
that day:可指以前的一段时间,
而on that day则指过去的某一天.
本句的意思是:有一阵子我们家个个都挺开心的.

A is right.

B.that day. 对
这个和I'm lucky this year 一个道理

B对.
这个初中时候经常玩.老师每天提着耳根讲~~

A.on that day

题目有误:My family were very happy____才对!
B.that day.对
由this,that引出的时间状语前面常省略介词.

A具体的一天用on
