Of all my teachers, Mr Mike is the one who impress me most. Though he is 35, but he looks very young for his age. And he's one of the most popular teacher in our school.

Comparing with other teachers, Mr Mike pays much attention to his way of teaching. He tries various ways to make his class lively and interested. In his opinion, we should not only know “what”, but also understand “why”. So, instead of giving us answers immediate, he encourages us to think by myself whenever he puts forward questions. Without his help, we've learned how to analyze and settle problems. What wonderful world of “ why” he leads us to !

He is such a learned person that we all admire him very much.
