黑板
3925.jpg)
黑板是能让粉笔于上面标记的平面，通常用作书写。
黑板可以是一块漆了深色颜料（通常是深绿色或黑色）的板。黑板下方通常会有一个窄长的架，能放置粉笔和黑板擦。
黑板常用于教学。用沾了水的布或黑板擦（一块带毡的木，或一个用布卷成的物体）便可轻易去除粉笔迹。在湿的黑板上书写，那些粉笔迹难以抹除。
黑板的缺点在于使用时会产生不少尘埃（就粉笔的质量而定），有些人会因此而觉得不适，甚至引致呼吸困难。可是，其他显示信息的方法更昂贵且亦有不足之处，所以至今黑板在教室里仍然被广泛使用。但在一些地方，不会产生尘埃的白板开始渐渐取代黑板。

Blackboard 黑板
A blackboard (also known as a chalkboard) is a reusable writing surface on which text or drawings are made with sticks of calcium sulfate or calcium carbonate, known, when used for this purpose, as chalk. Blackboards were originally made of smooth, thin sheets of black or dark grey slate stone. Modern versions are often green because the colour is considered easier on the eyes.
