9. A professor’s mannerisms can either help or hinder communication in the classroom, and they can also show whether or not he is interested in the students or the subject. Consider the classroom behavior of Dr. Axe, my English 100 instructor. Unshaven, wearing a blue beach shirt, searsucker pants( 泡泡纱裤子 ), and a pair of sandals （便 鞋） with no socks, Dr. Axe would habitually trudge （蹒 跚地走） into the classroom late. After dragging himself to the center of the room and dropping his attache case on the desk, he would call the roll, never smiling, never saying good morning. He would collapse in his chair with a weary sigh and proceed to read an essay out loud to the class. Now and then, as if he were drifting off on a cloud to Venus, he would pause to gaze at the scuff-marked floor. Then he would continue reading, pausing every few minutes to entertain a reverie.
