以The Most Unforgettable person I Ever know为题目写一篇不少于100词的作文

In my life I have met a great many people who are really worth recalling. But perhaps the most unforgettable person I ever know is my English teacher. What frequently brings back memories of my school teacher is his special qualities. First and foremost, he gave us the greatest gift a teacher can offer—an awakening of a passion for learning. He not only led us to an appreciation of the beauty and perfection of English language and literature, but also aroused our great interest in exploring something deeper in this field. Furthermore, I was attracted by his lively wit. I remember that we students always anticipated his class with great eagerness because his lecture were humorously delivered, never failing to provoke chuckles or loud laughs. Although it is nearly two years since I attended his last class, he is the talk of our old classmates, and I know part of him has already stayed in my heart.
