英语翻译
If at that time we point the hour-hand at the sun ,the hour-hand and number one will point south .This is why you must imagine a line which will run from the center of the watch through a point half-way between the hour-hand and number one.It will point south if you are in the southern part of our plant ,you must point number 12 and the hour-hand will then show nouth.
知道的帮忙翻译下
Do you know that you can use your watch as a compass on a sunny day?Take a watch and point the hour-hand in the direction of the sun .Imagine a line which runs from the center of the watch through a point halfway between the hour-hand and number one .This line will surely point south.
If you know astronomy a little ,you will understand how this works .In the north part of the earth ,the sun is in the south at noon.In Russia ,the real noon is one o"clock .
这是前两段

你知道吗?有太阳的时候我们可以把我们的手表当做指南针来用.拿块手表,将时针所指的方向对准太阳所在的方位.假想一条穿过手表中心的线作为时针和一点钟方向所成夹角的对等分割线,那么这条分割线指向的肯定就是南方.
如果你懂点天文学的话你就会知道其中的原理.在北半球的话,中午的太阳是在南方的.在俄罗斯,真正的中午其实是一点钟.
