一个星期六的上午,我做完作业后,便看起了平时最喜欢看的《发明发现的故事》。当我看到《指南针》一文时,顿时被指南针的“神奇”本领所吸引。通过阅读我了解到指南针是我国的四大发明之一,早在两千多年前,我们的祖先就发明了一种叫“罗盘”的工具,这便是最早的指南针了。“罗盘”是由一块磁石做的汤匙和光滑的铜盘组成的,用手轻轻地转动匙柄,等它停下来的时候,匙柄所指的方向就是南方了。 One saturday morning, after I finished my homework, I looked at my favorite story of discovery. When I saw the “compass” article, I was immediately attracted by the “magical” ability of the compass. By reading I learned that the compass is one of the four great inventions in our country. As early as two thousand years ago, our ancestors invented a tool called the “compass”, which is the earliest compass. The “compass” consisted of a magnet made of a spoon and a smooth copper plate, gently turning the handle with the hand, and when it stopped, the handle pointed to the south.
