The last night I staying home

Time flies! I have been home for a month, and now it's time to for (or - to go to) school. I am a little upset, because it means that I am going to leave my hometown and my friends.  But at the same time, I feel excited! For I would will meet my friends in Beijing two days later. How a Such complex emotions humans have!
Our summer vacation is always from July 10th to September 1st. It turns out to be that I come back to school more earlier than my friends. But why? Just because we are going to have a half-month military training. As we all know, every college student must finish it. It is usually carried out at in the freshman year, but because of some special reasons our training has been put off! The training includes many kinds of activities, such as standing  a pose of a soldier, running, goose-step and so on. Maybe you would think that's a small thing case, but you are really wrong!  Because that should be would finish under the hot sun, and you must stand all day long! Sounds really scary, right? But you would learn many much from it, I think, such as courage, persistence, etc.
I am looking forward to my military training and would will try my best to enjoy the difficulties in it!

excellent!

be careful with the 'would' and 'will'.   'Would' means something might happen if some circumstance is met.   'Will' means it is going to happen.  It can definitely be a subtle difference.
