My friend

My friend's name is Xiao Lei. He is very smart. Xiao Lei is always ready to help me. (better: Xiao Lei is always <em>willing</em> to help me) I am thanks grateful to him for his help. I hope May he be happy to him every day. I can want to study hard to so I can help others an as well as him.

Very good writing overall. Don't forget to capitalize the first letter of proper nouns (your friend's name), and notice there shouldn't be a space before periods.
