我平时用过的作业本、试卷还有草稿纸,基本上都无法再次使用,感觉有些浪费。因此我想发明一种“微型废纸转化机”。这种机器跟手提电脑差不多大小,主要有净化区和染色区两个功能区。净化区里装有能吸收油墨和色素的微型机器,染色区里则装有各类染料。当你把用过的纸放进废纸转化机里,按下净化键,出来的就是一张张崭新的白纸。如果你喜欢彩纸,把白纸放进机器里,按下染色键,就可以得到各种颜色的彩纸。 I usually used this homework, papers and scratch paper, basically can not be used again, I feel a bit wasteful. So I want to invent a “micro-waste paper conversion machine.” This machine is almost the size of a laptop computer, there are two main purification area and staining area. Purification area is equipped with a micro-machine can absorb ink and pigment, dyeing area is equipped with various types of dyes. When you put used paper into the waste paper conversion machine, press the purification key, it is a new piece of white paper. If you like colored paper, the white paper into the machine, press the dye key, you can get colored paper of various colors.
