【正确答案】The two pictures show what students are doing when the teacher is talking in the front. The first picture is showing a boy playing with his cell phone and in the second picture he is sleeping. The students are supposed to listen to the teacher carefully, but they are not. They behave just as they have nothing to do with the class.
I feel very sad about this phenomenon. The primary task for students is putting all their energy on learning, but they behave in an opposite way. There is so much knowledge and many skills for everyone to learn. People as young as students are in their golden age to learn new things. If we just let this period of time pass by without doing anything, we will regret in the future.
Therefore, I think students should behave like students and do what they are supposed to do.
