◇Natural ways of keeping time
In ancient time, people had to use the sun and the moon to tell time. They got up when the sun came
up and worked in the fields until the sun went down.
◇Man-made things
The sand clock is made of two glass balls joined in a narrow neck. The top ball was filled with sand.
The sand slowly moved through the neck into the bottom (底部) hall. People knew the time by watching

bottom of a pot. When the water in the pot dripped (滴) out, marking (刻度) inside the pot showed how
much fame passed.
