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. |

Cable television can help people receive TV programs that they can not get with their ordinary (常规) antenna. Television signals (信号) travel in straight lines in all directions. Signals from a TV station move towards the horizon (地平线) and then go into space. If people live only a few miles from a TV station, they may get a good picture on their televisions. But if they live more than 50 miles from a station, they may not get good pictures. CATV began in 1948. People in places far from TV stations had to pay for it. A community antenna was usually placed on a hill, a mountain or on a high tower. The antenna can receive TV signals and send them into a small local station (当地电视台). Today, cable television is used in more and more areas. It is even used in many classrooms all over the country. | ( ) 1. Most people like using the name of "cable television". ( ) 2.
