英語の添削お願いします
こんにちは。
来週のspeakingの授業でスピーチをすることになりました。
お題は「大切な友達について」です。
内容は書き終えたのですが、自分の文章が100%合ってるか自信がありません（むしろ、間違いの方が多いと思います。）
自分でも、一応見なおしたのですが、客観的な見地からの意見が欲しいです。
どうか添削お願いします。
I’ll introduce my friend,（name）
We have known each other since elementary school days.
When we were junior high school students, we joined same tennis club.
That's why I know him a lot.
He has two characteristics, Kindness and glutton. (Glutton means a person who eat food very much.)
First, I’ll explain how kind he is.
When I was a fifth grader, I played tag with my friends.
(In order) to run away from it, I hid myself under the bridge.
Then I made mistake and fell from three meters above, and I put my hands on the ground and had my wrists broken. Due to the accident, I thought that I spent terrible days for a month in elementary school. I couldn’t really take notes, go to the toilet, put on P,E uniform and so on. However, (my friend's name) always supported me.
Without him, I couldn’t enjoy my school life for the month.
I thanked his kindness and wanted support him, if he was in trouble.
Second I’ll explain how gluttonous he is.
He really eats very much. Whenever I hang out with him, he goes to McDonald's.
Even when we should share cakes, potato chip and other snack, he eats them almost by himself.
He is very kind, but I think he should stop the habit of eating so much.
I hope that he don’t ruin himself for glutton.
「kind」の内容と「glutton」の内容のバランスの悪さは承知の上です。
二分間という制限なのでこの程度が適当ではないかと思いました。
（ ）部分は友人の名前が入るのですが、友人の名前は非公開にさせていただきました。
