An idealistic figure of English teacher in my mind

Q.What type of English teacher do you want to be? Describe an idealistic figure of English teacher in your mind and explain why.

Most of all, i think a good English teacher should know how difficult it is for students to learn English as a second language and a teacher should guide them to study English well.
Teachers must be equipped with many different ways to teach students so that they could help each students with various ways.
Also, a good English teacher has to know what parts of English students are having trouble studying. In that way, students will have more opportunity to develop their English skill in a short time!
