下面的段落符合段落四个要求，请你分析并赏析作者是怎样使得段落有效的？ I don’t teach because teaching is easy for me. I teach because I like the pace of the academic calendar. June, July, and August offer an opportunity for reflection, research, and writing. I teach because teaching is a profession built on change. When the material is the same, I change — and, more important, my students change. I teach because I like the freedom to make my own mistakes, to learn my own lessons, to stimulate myself and my students. As a teacher, I’m my own boss. If I want my freshmen to learn to write by creating their own textbook, who is to say I can’t? Such courses may be huge failures, but we can all learn from failures. I teach because I like to ask questions that students must struggle to answer. The world is full of right answers to bad questions. While teaching, I sometimes find good questions.
