现在的高中生可忙了,课桌上的书堆放多了,一不小心就会掉落到地上,引起一阵声响,影响其他同学的学习,并且有些同学还利用这道“屏障”来遮挡老师的视线,偷偷地睡觉。 Nowadays high school students can be busy. Books on the desks are piled up. If they are accidentally dropped, they will fall to the ground, causing a sound and affecting the learning of other students. Some students also use this “barrier.” Block the teacher’s eyes and sleep secretly.
