Many people like to search the Internet. Exploring the Internet is one of the most important activities of the day. The Internet brings the outside world closer to people"s homes. Some people say the world is smaller than before because of the Internet. What"s going on in other countries? How do people live in places far away? Is there a good sports game somewhere? What"s the life like in the deepest part of the sea? If you want to answer all these questions just come to the Internet. Of course people can also learn through reading or listening to the radio. But with the Internet they can learn better and more easily. A lot of information (信息) can be collected at a great speed. Can we go shopping without leaving home?

All these things seemed to be impossible but now they have become quite possible. The Internet helps us open our eyes. The Internet also helps us open our minds. The Internet often gives us new ideas. In a word it helps us in many ways. Great changes have taken place in our life since the use of the Internet. |

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 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. |

When you run downhill, gravity pulls you. When you throw a ball up, gravity pulls it down. When you sit, gravity holds you down. When you lie down, gravity holds you to the bed. We know gravity is everywhere even though we can"t see it.We know it pulls on every stone and every drop of water. It pulls on everything. The gravity of the earth pulls everything towards the center of the earth.You know this when you try to lift a heavy stone. Gravity pulls it down. The more the stone weights, the more gravity pulls on it. To lift the stone, you must pull up harder than gravity pulls down. The earth has gravity and the moon also has gravity. The moon has less gravity than the earth has. This means the moon"s gravity does not pull as hard as the earth"s gravity. Do you weigh 60 kilograms? That means the pull of the earth"s gravity on you is 60 kilograms. If you were on the moon, you would weigh only 10 kilograms. The pull of the moon"s gravity on you would be only 10 kilograms. |
1. The word "gravity" in the passage means "______" in Chinese. |

A. 物体质量 B. 物体重量 C. 万有引力 D. 宇宙能量 |
