One possible version:
Yesterday we invited Mr. Li, a famous scholar and schoolmate of our school to give a speech to us Senior 3 students. All of us felt deeply touched by his lecture and proud of our distinguished schoolmate.
Mr. Li once studied in this same school many years ago and later he went to a famous university in the North. After graduation, he devoted his life to teaching in the rural areas of our country for more than 30 years. His devotion and selflessness are highly thought of by all his students as well as by the society. Meanwhile, he donated many books to our school and showed deep affection to his former teachers and his high school.
As a senior high school student, I’m determined to learn from Mr. Li and become a worthwhile schoolmate of our school.
