幫我修改一篇小學(xué)英語文章,看看有沒有語法,句型,時態(tài)等方面錯誤.
這是一封Sunny寫給Ann的回信,講的是他的生日聚會描述生日上的情景使用過去式（老師說的!）但最后一句話時態(tài)不確定.其余句子語法也不肯定.信的格式除去,這是正文：
I had a good time on my birthday party.Many friends came to my home and I received many gifts.We sang ang danced,Mike did Chinese kung fu.Amy and Ed are playing the piano.John is played games.My parents bought many good food and a birthday cake for me ,we ate a lot.Ann ,I waiting your present,come back quickly please!
