Please correct my mistakes.

Hello everyone! My name is Keita. Today, I’d like to introduce my favorite object. However, I’d like to speak a little a bit about my hobby before that. My hobby is playing soccer, and actually I had belonged to soccer team for 9 years from when I was in the first grade of elementary school to the third grade of junior high school. As you know, we need some objects to take part in a soccer game such as a soccer ball, a uniform, a pair of spikes and things like that. Some of you may have already realized what my favorite object is. Returning to the main topic, my favorite objects are the spikes that I used when I took part in a soccer games (This just sounds a little more natural than "in a soccer game"). I can’t remember how many spikes I had bought over 9 years, but my most important one is the first one, and my favorite is the last one. I didn't bring it here today; it’s its color is green and yellow and it is sold by a famous brand, NIKE. The reason why I think that the last one is my favorite is that it fits my feet very well and I like the color and design. In addition to these good points, it reminds me of my last match and makes me nostalgic. I want to play soccer with my team mates again someday. Thank you for listening.

Great job!
