There is a handsome boy. He has golden hair and a pair of big blue eyes. But he looks very sad. He is thin and weak because he suffers from AIDS. In healthy human bodies, the immune system(免疫系统) protects them from diseases. But when one gets the AIDS virus(病毒) in his/her body it attacks and destroys the immune system, and the body then is helpless against diseases. And the patient will die of this or that disease. But you don"t have to worry too much about being with the boy. The AIDS virus can"t live outside his body, and it can"t travel through the air. You don"t need to be afraid to touch him, either.

During the day we work and play and at night we sleep. Our bodies rest while we sleep. In the morning we are ready to work and play again. It is while we are asleep that our bodies grow most.

Many animals use some kinds of "languages". They use signals (信号) and the signals have meanings. For example, when a bee has found some food, it goes back to its home. It is 1 for a bee to tell the other bees where the food is by speaking to 2 ,but it can do a little dancing. This tells the bees where the food is and how far it is. Some animals show how they feel by making sounds. It is not difficult to tell if a dog is angry 3 it barks (吠). Birds make several different sounds and each has its own meaning. Sometimes we humans make sounds 4 . We make sounds like" Oh" or" Ouch" to show how we feel about something or when we drop something on our feet. We humans have languages. We have words. These words have the meaning of things, actions, feelings or ideas. We 5 give each other messages to tell other people 6 we think or how we feel. By writing down words, we can remember what has happened or 7 messages to people far away. Languages, like people, live and die. If a language isn"t used by people, it is called a dead language. This language can not live and grow because 8 speaks it. Latin is an example of a dead language. A living language, of course, is often spoken by people today.It grows and changes with time.

Why do earthquakes happen? Scientists explain that the outside of the earth is made of a number of different plates(极块). For example, at San Francisco the Pacific Plate which is moving towards the northwest meets the North American Plate. The Pacific Plate is moving very slowly-at 5. 3 centimetres a year. Sometimes these two plates stop and do not move for years. Then suddenly, they jump and an earthquake is felt. As the movement of these plates,West America near the sea has always been a bad place for earthquakes. When the 1906 earthquake happened, the Pacific Plate jumped 5-6 metres to the north. We cannot stop earthquakes, but we can do things to make sure they don"t destroy(毁坏) the whole of cities. First,it is not a good idea to build houses along the lines, where two of the earth"s plates join together.Second, if you think there may be an earthquake, it is better to build houses on rock not on sand. Third, you must make the houses as strong as possible. Weak buildings will fall down in an earthquake,but strong ones may stay up. | |||
