看着手中精美的书签,我突然间失落起来,它原本不属于我。几分钟前,一名经常来我校推销书籍的中年男子在班级的讲台上留下了一叠厚厚的书签。刚才还漫游在数学题中的同学纷纷抬起头。“好精致的书签!”前排女生感叹道。如果现在是小学三年级,八成大家会一涌而上,抢着往自己的口? Looking at the exquisite bookmark in my hand, I suddenly lost it. It didn’t belong to me. A few minutes ago, a middle-aged man who often came to our school to sell books left a thick stack of bookmarks on the class’s podium. The classmates who had just roamed in mathematics questions raised their heads. “Sophisticated bookmarks!” sighed at the front row girls. If it is now in the third grade of primary school, will 80% of all people surge in and rush to their own mouth?
