lilei
Li Lei is one of my best friends.He is a helpful and outgoing boy who has a variety of hobbies.
He always comes to my aid when I have problems in studying because he does very well in studying and is willing to help others.
I am really grateful to him for his help and kindness.I plan to give him a gift to express my gratefulness.Due to the reason that I consider him as a person who helps others without expectation of a reward,I decide to write a letter as a gift.
I hope that he can keep his good qualities and grades,and he will always be happy and be my good friend forever.
1樓寫的還行，但是有壹些錯誤，optimistic意思是樂觀的，外向用outgoing更合適。
because of his helps，help作名詞：幫助時為不可數名詞，不用復數形式。
I wish he can，wish後面用虛擬語態，can改成could，而且wish壹般表示渴望或者難以實現的願望，在這裏使用不是很合適。
