Many students feel that a popular teacher must be kind and easy going.He or she should make the class very active by joking with the students.Howerver,the popular teacher is at the same time the one who should be strict with students.Last year,my English teacher was proved to be the most popular in our school.She was ysual(?) patient with her students and never made them disappointed.She always stayed in full control of the situations.She always made sure that our homework was finished on time(这两句的时态应保持一致,但是个人认为一般现在时更准确),and she marked strictly on students' actual performance.
