| Different from popular thoughts, colds are not caused by bad weather. Colds are caused by viruses (病毒) in the body, and you are better out on the snowy day than you are in a warm room, with your friends, who just may be passing the virus around. If you feel a chill (寒冷) when you are coming down with a cold, you are already sick. A chill is an early sign of the cold. The virus can spread through air when a cold-sufferer (感冒患者) coughs or sneezes. Surprisingly, this is not the most usual way of spreading, Many studies have now shown that most colds are "caught" by hands. A cold-sufferer rubs her nose, so spreading the virus to her hand. Then a friend comes to visit her. They shake their hands. The friend then gets something to eat by hand, and several days later she catches a cold. Although some parents pick up their children"s tissues (纸巾) and carefully throw them away, they fail to wash their hands. They"ll catch the colds, too. Cold viruses can also be spread by objects, for example, telephones, plates. The cold-sufferer as well as other members of the house, by washing their hands often, will stop the viruses from spreading in a way. |

| Have you ever seen the film Traveling Bird? In the film, groups of birds fly high above the sky and cross the way above snow, rivers, fields, sea and grassland. I"m sure you will love the beautiful picture when you see the film. But you may not feel so good if you have learnt about bird flu (禽流感) from TV or on the Internet. Some governments had to kill chickens in their cities. A large number of chickens and even some people died in Asia, and nearly 8,500birds died in Russia because of bird flu. Chickens can get bird flu from the feces (粪便) of the passing birds. It is not so difficult to control the chicken in cages or on farms. But it is much more difficult to control the birds in the sky. Luckily, scientists have found a medicine for bird flu. But the virus (病毒) can change easily and quickly. So bird flu is still a serious problem we must face. |

| Since the earliest times, trees have always been very useful and important to man who made use of them in many ways. Even today trees continue to serve man in many ways. Trees provide man with fruits and building materials in the form of wood. Without trees it would be impossible to build houses, boats and even bridges. Furniture such as tables, chairs and beds is made of wood. In the tropics (热带地区) where it is very hot all through the year, trees protect man from the terrible heat. They are also useful.in preventing good and rich top soil from being washed away during heavy rains which are so common in the tropics. If there were no trees or vegetation (植被) of some kinds to hold back the soil with their roots, heavy rains would wash away the rich surface soil that is so important and necessary to agriculture. The result is that the land becomes a desert. There are so many desert areas in the world. A long time ago these desert areas must have been very rich fertile (肥沃的) areas, but since our ancestors (祖先) in the distant past had no enough knowledge about science of nature, they cut down all the trees in the areas where they lived and never planted new ones. By and by, the rich surface soil was blown away and washed away by strong wind and heavy rain. In the end the land was turned into useless deserts where nothing could grow. |
