求翻译：It is a pleasure for me to provide an evaluation in support of the application of Mr. Cai Yubiao, whom I have known for six years and taught English for three years in middle school. Later I acted as counselor of his class and he became my friend. I have full understanding of him in many aspects and I can say responsibly that he is a rare excellent student our school has produced.是什么意思？
