綜合訓練（六）朗讀短文-Mr.Liu.m4a

00:56 來自劉凱老師

The blackboard is something that is found in almost every school classroom. However, it is actually a recent invention. In the past, students and teachers would write on individual tablets made of stone or wood because paper and ink were very expensive.

Because everyone had their own small tablet, teachers had no way to present a lesson to their whole class, meaning they had to go to each individual student. It was not until 1801 that a teacher invented the first modern blackboard. He made it by hanging a large thin piece of stone on the classroom wall.

Even though some schools have introduced some technology into the classroom, blackboards still have advantages over complex modern technologies. They are cheap to make and effective. Another obvious advantage is that they are easy to use.

因為每個人都有自己的小平板電腦，老師沒有辦法向全班展示一堂課，這意味著他們必須去找每個學生。直到1801年，一位老師才發明了第一塊現代黑板。他在教室的墻上掛了一塊又大又薄的石頭。

黑板幾乎在每個學校的教室里都能找到。然而，它實際上是最近的一項發明。在過去，由于紙和墨水非常昂貴，學生和老師會在石頭或木頭做成的單獨的平板上寫字。

盡管一些學校在課堂上引入了一些技術，但黑板仍然比復雜的現代技術有優勢。它們制造成本低，效果好。另一個明顯的優點是它們易于使用。
