一、奇怪的丢失现象学期过半，有孩子反映铅笔、橡皮等学习用品找不到了，我总是嘱咐他们好好找找，过后便忘了这事。渐渐地，有家长也反映，孩子的两块新橡皮不见了。我不以为然，认为有可能在讲台上，因为那里有为数不少的无人认领的学习用品，孩子们贪用新的，不屑再用。慢? First, the strange phenomenon of loss Semester more than half of the children to reflect pencil, eraser and other learning supplies can not find, and I always asked them to look for it, after that forgot it. Gradually, some parents also reflected that the child's new eraser disappeared. I disagree, I think it is possible in the podium, because there are a large number of unclaimed school supplies, children use the new, disdain and reuse. SLOW?
