17.If you can read a clock,you can know the time of the day.But no one knows what time itself is.One way to think about time is to imagine a world without time.But there could be no movement,because time and movement cannot be separated.In early human history,the only changes that seemed to repeat themselves evenly(有规律地)were the movements of objects in the sky.The most easily seen result of these movements was the difference between light and darkness.The sun rises in the eastern sky,producing light.It moves across the sky and sinks in the west,causing darkness.The appearance and disappearance of the sun was even and unfailing.The periods of light and darkness it created were the first accepted periods of time.We have named each period of light and darkness one day.People saw the sun rise higher in the sky during the summer than in winter.They counted the days that passed from the sun's highest position until it returned to that position.They counted 365days.We now know that is the time Earth takes to move once around the sun.We call this period of time a year.
They also developed a way to use the changing faces of the moon to tell time.The moon was"full"when its face was bright and round.The early humans counted the number of times the sun appeared between full moons.They learned that this number always remained the same-about 29suns.We now know this period of time as one month.
Early humans hunted animals and gathered wild plants.They moved in groups or tribes from place to place in search of food.Then,people learned to plant seeds and grow crops.As hunters,people did not need a way to measure time.As farmers,however,they had to plant crops in time to harvest them before winter.They had to know when the seasons would change.So,they developed calendars.
No one knows when the first calendar was developed.But it seems possible that it was based on moons,or lunar months.

A.reliable B.everlasting C.limited D.changing
