用小木棍分方向/一个小木棍,你知道它有什么用吗?现在,我们来学习用小木棍辨别方向。中午时候,太阳在你的头顶上,找一根小木棍垂直插入地面,你会发现木棍在地面上投下一个阴影。这时,你可在阴影的顶端作上记号。过了一刻钟以后,在阴影的顶端你再作一次记号;然后,将两点连接起来,就构成了东一西轴,它的垂直线就是南—北轴。东南西北一看就明白了,你怎么会迷路呢?(见图) Do you know what’s the use of small sticks / small sticks? Now, let’s learn to use sticks to identify the direction. At noon, the sun in your head, looking for a small stick inserted vertically into the ground, you will find the stick cast a shadow on the ground. At this moment, you can mark the top of the shadow. After a quarter of an hour, you make another note at the top of the shadows; then, by connecting the two points, you form the east-west axis and its vertical line is the south-north axis. Look at the southeast and northwest to understand, how do you get lost? (See photo)
