【正确答案】[范文] In the picture above, the teacher is staring at the boy who is thinking about a plane and has not noticed the teacher. Obviously, the teacher is furious. It is evident that the boy's inattention to class is wrong-doing. Firstly, inattention to class signifies that one does not have a right attitude to class, which is irresponsible for oneself. Being a student, we should listen carefully to the teacher to acquire knowledge and only by doing so can we enrich our mind and progress gradually. Secondly, inattention to class conveys a message that one does not show respect for the teacher and the teacher's work. The teacher did a lot of preparations before class and tried his or her best to give the lecture in class with the purpose that the students can learn as much as possible from him or her via the lecturing. Then if we are absent-minded in class, we do not value the teacher's efforts, which, in essence, is a kind of disrespect for the teacher. To conclude, whatever happens, being a student, we should concentrate in class to be responsible for ourselves and respect the teachers.
