每天早上来到班级,第一眼看到的总是那块又大又干净的黑板。昨天放学时,黑板上还全是粉笔印,值日生却认认真真的把黑板擦洗得一尘不染。但是我发现值日生在擦黑板的高出时,总要跳起来,许多落下的粉笔灰还会呛着同学,害得同学直咳嗽。我想发明一种多功能的黑板擦。这种黑板擦十分神奇,它有几个按钮,红色的是用来擦黑板高处的。红色按钮轻轻一按,黑板擦下方会出现一个折叠式的教棒,这样会让个子矮一些的同学擦黑板的时候不用又蹦又跳的了。如果不用折叠教棒了,只需要再按一下红色的按钮,就可以收起来了。一个绿色的按钮,是用来洗黑板的。按这个绿色的按钮要稍稍用力一些,因为如果按得很轻,同学在擦黑板的时候会不小心按到它,黑板擦的表面会渗出水来,这样就不能擦黑板了。但是按到它也没有关系,只要走到桶边,再按一下白色按钮,就能把黑板擦布上的水快速挤压干了。还有一个黄色的按钮。是用来吸取粉笔灰,就如一个吸尘器。同学在擦黑板的时候,就不会被粉笔灰呛着了。最后是一个蓝色的按钮,可以把黑板擦里面的吸取的粉笔灰里的收纳盒拿出来,再把收纳盒里的粉笔灰倒入垃圾桶。这就是我的“金点子”,一个神奇的黑板擦
