The promote of my english teacher

I have a good English teacher whose name is WANG. He is a tall and thin person, wearing a pair of glasses which makes him more like a gentleman. He is strict with us. He often makes full preparations for his class and corrects our homework carefully. His teaching style is very unique, because he is used to encouraging all of us to think by ourselves and study on our own. The relationship between WANG and us is harmonious. He is so kind and friendly.So his teaching promote my english become better and better.
