一天,芊芊不小心把桌上的杯子碰翻了,活动室里顿时乱成一团。孩子们有的嚷着要去报告老师,有的出主意让芊芊赶快把水擦干净,有的干脆用手把桌上的水往地板上抹……正在这时,老师来了。她没有责怪孩子们,而是抓住时机引导孩子们想办法帮水搬家。晨晨说:“用手抹。”老师请他做给大家看。大家一致认为这个办法不行。理由是:手不但抹不干桌上的水,反而会把水洒到地板上,这样小朋友就会有摔跤的危险。接着,大家七嘴八舌地发表意见。归纳一下,大致有四种办法:①用布擦,②用纸擦,③用棉花擦,④用注射器吸。这些办法到底怎么样呢?
One day, accidentally knocked over the cup on the table, the activity room suddenly chaos. Some of the children clamored to report to the teacher, some of them had their idea of getting rid of water quickly and some simply wiping the water on the floor with their hands ... At this moment, the teacher came. She did not blame the children, but seized the opportunity to guide children to find ways to help move water. Chen morning said: “wipe with your hands.” The teacher asked him to do for everyone to see. We all agree that this solution will not work. The reason is: the hand not only wipe off the water on the table, but will sprinkle the water on the floor, so that children will have the danger of wrestling. Then, everyone said their opinions. To sum up, there are roughly four ways: ① wipe with a cloth, ② paper wipe, ③ with cotton wipe, ④ use a syringe to suck. How are these solutions?
