我该怎么用英文解释啊？

The so-called "Military training" is not what you have in your mind.
A military training never goes to the army.It is the drillmaster who is in the army comes to our school.
The military training aims to train our determination.They use the way used in the army to train in order that we have a strong will to face the senior life afterwards.For example ,the drillmaster often order:" parade step",and we will do that.
However,we will be exposed to the sun.As you know,it's always hot at this time of the year.So that's the way the train our wills.
The military training usually lasts for a month.And it's a must for senior students.
It's a little like summer camp, but it's not so interesting.
A little boring.You do the same thing --walk or run or sit or squat,again and again.
When taking a break, one class often asks others to sing a song.
I hope you can understand.
