By the time Dad and Mom received this package which we are mailing today,
we shall have returned home.
"which we are mailing today"作为非限制性定语从句来修饰package.所以逗号
去掉.
by the time出现,主句一般用过去完成时,从句用过去时.
表示事情发生在从句之前.
有 不知道 都荡了开去还久久不息啊，读着都别扭 只求意味的话，不讲究语法
By the time Dad and Mom receive this package which we mailed today,
we shall have returned home.
没有错误 只需把which前面的逗号去掉 即可 这是限制性定语从句 当然定语从句的谓语 可以根据情况 是一般过去式 现在完成时 一般将来时 原句用进行时 也是表示的将来
We will have returned home, by the time Dad and Mom receive this package which we are mailing today.这地方的WHICH不能换用THAT。
We shall/will have returned home by the time Dad and Mom receive the package that/which we are mailing now.
