The word “day” has two meanings. When we talk about the number of days in a year, we are using “day” to mean 24 hours. But when we talk about day and night, we are using “day” to mean the time between sunrise and sunset. Since the earth looks like a ball, the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning（旋转）of the earth. At the equator（赤道）day and night are sometimes the same length（长度）. They are each twelve hours long. The sun rises at 6 o’clock in the morning and sets at 6 o’clock in the evening. For six months the North Pole is tilted（倾斜）toward the sun. In those months the Northern Hemisphere（半球）gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than nights. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.

One day, a farmer was walking along a road with his son Thomas. The father said, “Look! There's a horseshoe. Pick it up and put it in your bag.” Thomas said, “It isn't worth the trouble.” His father said nothing but picked it up himself. When they got to a nearby town, they had a rest. There the farmer sold the horseshoe and with the few pennies he bought some cherries.

    The father and the son continued their way. The sun was well up in the sky, and there wasn't a house or even a tree where they could have a rest. Thomas felt too thirsty to walk on. At this time, his father dropped a cherry on the ground and Thomas picked it up quickly and ate it. After a while, his father dropped another cherry and once again, his son lost some time in picking it up and putting it in his mouth.

    And so they went on. The old farmer dropped the cherries and the son picked them up. When Thomas had eaten up all the cherries, his father said to him, "My dear son, if you had bent down earlier to pick up that horseshoe. it would not have been necessary for you to bend so many times for the cherries. Always remember the lesson that anyone who does not worry about the little things will find that he cannot do the great things.

What do we do when we go camping? First, we work out a plan. We take food, clothing, a knife, and things for cooking and eating. We take things to keep us away from insects （昆虫）and the sun.

Then we put everything into the car and we drive to the woods（森林）. We look for a place for campers and we look for a good place for our tent（帐篷）. The place should have a lot of moving air. This will keep some insects away. High land with water on both sides of it is good. Then we put up our tent. We put everything into the tent, and we are ready for fun. We can swim in the lake, walk in the woods, climb a mountain, row a boat, or go fishing.

In the evening we come back to the tent, we build a big fire（火）， because it can keep the insects away. We sit around the fire and talk. We may tell interesting stories or we may sing songs.

At night we lie down on the grass. We can look up at the stars. It is a busy day, so we try to go to sleep early.

Everything is dark. Everything is quiet. We hope we won’t hear music from the radio in the next tent. We hope it won’t rain.
