短文写得情真意切哟,不过有点错误,我试着改改看
When my twentieth birthday came,in order to celebrate such an important day with my parents,I wrote a letter to them because I am studying far away from my home.In the letter I said that I was grateful to them for all that they had done for me because I knew they spent lots of effort raizing me up.I expressed my gratitude and love to me.Later my mother told me when she read the letter.Her tears ran down her face.But my father felt cool because I know being a man of few words,my fathere prefers to show his love to me in a silent way.Now as time passed by,my parents grow older and older.I really hope they can stay healthy and be happy all the time.
I really hope they can stay healthy and happy.主句是；I realy hope,从句：they can stay healthy and happy.的主语是they,谓语:can stay,宾语：healthy and happy.
