初二英语作文{my dream}写自己的梦（不是梦想）、应该用什么时态?（急）

When I was a naughty boy,may be because of the influence of the film."Xiao Bing Zhang Ga",my dream was to be a soldier just like Zhang Ga.I thought if I was a soldier,I should be able to swim,dive and climb trees as he did.It seemed to be very wonderful.So I began to learn swimming,diving and climbing trees.I practiced every day and finally I could do them well.But when I entered junior high school and had the military training.I suddenly found that being a soldier was very difficult and I wasn’t strong enough to bear it .I had to give my dream up.
But I wasn’t discouraged,and I had new aim,which was to be a postman,or rather to be a newspaper boy.As a newspaper boy.I could speed along streets on a bike and throw newspapers onto every porch.That’s also very cool.So I started learning to ride a bicycle.After the everyday practice,I could go very fast by bicycle.But to my disappointment,the job which I wanted only existed in western counties not in China,because there was no porch in China.And Chinese postmen had to stuff very thick newspapers into very small mailboxes from very narrow entrances.The job was far from what I had expected.So once again my dream fell through.
Perhaps you have had the same experience as I and most of your dreams haven’t come true yet.But I think it doesn’t matter,because if you have a dream,you’ll make many efforts to realize it.This course is really important.If I hadn’t dreamt of being a soldier or a newspaper boy.I wouldn’t have learned to swim,to dive,to climb trees or to ride a bicycle.Even if our dream can’t come true,you’ll learn much from the efforts you have made.So what I want to tell us is that dream helps us to grow up and teaches us how to control our lives .It is dream that gives us power and makes our lives colorful
