This is my first small composition(I'd like to know exactly what this kind of small articles' names are.) on italki. 
I'm now a middle school student and I'm going to have a really significant （important比较合适）examination to enter a good senior high school, so I spend most of my time （没有in）writing test papers. You know Chinese education is crazy, don't you?不爱国Schools are over late and we are ordered to take extra classes at night and on weekends. The thing 【that】torture三单 me the most isn't tiredness but stress. I have worked for my goal for 3 years and I worry about if I will get good marks. Whatever,用得好奇怪 however就好 I have some spare time. I love playing basketball and playing the piano. I have learned playing piano for 10 years. I also love watching NBA games. My favorite team is OKC(Thunder). Westbrook is the most outstanding player in my heart. Besides, I like shopping on line.That's what my life 【is】like. My dream is 【to】study没有ing in Tsinghua University, the best university in China. It's a hard way to go, but I will fight for my dream. 
I'm looking forward to your criticism这个词太重了，advice或correction感觉对一点.
