Question

2.The film standed half a hour ago.
3.He joined the army 3 years ago.
4.He left to XiiAn a week ago.
5.His grandma died last month

Answer 1

标准答案：转换成延续性动词句子要用现在完成时态，而不是过去完成时。
I have had this book for a week.
The film has been on for half an hour.
He has been in the army for 3 years.
He has been away for a week.
His grandma has been dead for a month.

Answer 2

I have had this book for a week.
The film have been on for half an hour.
He have been in the army for 3 years.
He have been away for a week.
His grandma have been dead for a month.
短暂性句子变延续性句子，注意看两个成分，一个是谓语动词必须变成可以表达一段时间的动词状态，一个是时间状语必须要把时间点变成时间段。
此外想确认第四个句子确实与原文相符吗？
