可以幫批改我的英文日記嗎?(好短)

I felt little embarrassed today when my math teacher found out I was reading a book of another subject in the class.

After lunch, we went to the ________ show at Wan Chai. I was overjoyed because I could buy a lot of souvenir. It was such an indulging day!

Some comment:
- 說明今日發生的事，因為已過去，所以應用過去式。
- 有一點詞性上的錯誤，如：
I had a little embarrass {應是名詞但用了動詞}
I look others {應是形容詞other，但用了代名詞others} book
This is a good chance allow to let off of me {太轉折}
改成：This was a good chance to let off of myself.

I was embarrassed when I was found by teacher to look other book in Maths lesson. During lunch time, we left for Wan Chai to present something. I was so happy that I got many souvenirs, which made me a relaxation.
