As a student, I have gone through many different teachers. Male or female, young or old, they all have their own characteristics. But one of them, Mr Wu, has left me a deep impression. Mr. Wu is at his thirties, tall, thin. What strikes me most about him is his rich knowledge and sense of humor. Every time he's giving us a lesson, he makes it interesting. He not only explains the knowledge in the textbook, but also tell us a lot of related stories outside. We never fall asleep in his class. What's more, he's full of sense of humor. He never let one of his students feel embarrassed. That's why I like him so much.
