My favorite class in high school

My favorite class in high school is English grammar when I was 12th grade. Before I was 12th grade, I didn’t like English grammar. Because I couldn’t understand explanation of English grammar which English grammar’s teacher I was 11th grade or less. But, next year, new English grammar’s teacher came to my high school. He was very unique and interesting because how to speaking was very interesting. And, his explanation of English grammar was easy to understand. He taught us kindly why this answer is collect. I haven’t seen his angry since he came to my high school. He was very kind, too. I think there was no people who dislike him in my class. I have told with him out of class.
