Kinds of teachers

When I lived in Beijing, I had two teachers who were good for me in my school. First of all, teacher Ning was kind for me in my life. For example: she was the best teacher, and looked like a kind grandma. When we didn't study hard, she was also critical of us. One day, I make a noise. She was very angry and strict for me. When we studied very hard, she praised us and gave us a red flower. She loved us very much, and I loved her very much. Secondly, teacher Lu was also kind for me. She was a really strict teacher. When we didn;t finish the homework or correct the wrong questions, she never let us go home, and kept us in the classroom until we corrected the questions. But she taught the class very well, and she was also the best teacher in my life. In conclusion, I remember them in my life, and they gave me an impression.
