The sun might be the worlds first“clock”, except in the far north，where the Eskimos（爱斯基摩人）liveThere，its dark most of the winter, and light most of the summer. But in most of the world, if you dont have a clock that shows time, you still know that when the sun shines, its day, and when its dark, its night. The sun can not only yell you whether（是否）its day or night but also its morning, noon, or afternoon When the sun is almost directly（恰好）overhead, its noon. People who live near the sea learn from the tides. In the daytime, for about six hours, the water rises higher and higher on the beach. And then it goes down and down for about six hours. The same thing happens again at night. There are two high tides and two low tides every 24 hours. Seamen on a ship know time by looking at the moon and the stars. The whole sky is their clock. In some places in the world the wind comes up at about the same time every day or changes direction or stops blowing. In these places the wind can be the clock. A sand clock is an even better clock. If you had fine dry sand in a glass like the one in the picture, you would have what is called an hourglass. The sand in the hourglass goes from the top part to the bottom part in one hour. When the hourglass is turned over, the sand will take another hour to go back again.
