29、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. They are each twelve hours long. The sun rises at 6 in the morning and sets at 6 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 night. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.

1. When the Western Hemisphere is having day, the Eastern Hemisphere is having ______.

A. both day and night      B. day             C. neither day nor night       D. night

28、You speak, write a letter, make a telephone. Your words carry a message. People communicate with words. Do you think you can communicate without words? A smile on your face shows you are happy or friendly. Tears in your eyes tell others that you are sad.

When you put up your hands in class, the teacher knows you want to say something or ask questions. You shake your head, and people know you are saying "No". You nod and people know you are saying "Yes". Other things can also carry messages. For example, a sign at the bus helps you to know which bus to take. A sign on the door helps you where to go in or out. Have you ever thought that there are a lot of signs around you and that you receive messages from them all the time? People can communicate in many other ways. An artist can use his drawing to tell beautiful mountains, about the blue sea and many other things. Books are written to tell about all the wonderful things in the world and also about people and their ideas. Books, magazines, TV, radio and films all help us communicate with others. They can help us to know what is going on in the world and what other people are thinking about.
