     Many students feel it that a popular teacher must be kind and easy-going. He and she should make the class very active for joking with the students. However, the popular teacher is at same time the one who
should be strict in students. Last year, my English teacher proved to be the more popular in our school.
She was usual patient with her students and never made them disappointed. She always stays in full control of the situations. She always made sure that our homework was finished on time, but she marked strictly
on student’s actual performance.
