    Germs（细菌） are everywhere. You can’t see them, but they are on your desk, on your computer, and even in the air! Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.

    Warmer Weather Brings Germs
    The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches,  fever, and can even kill people.
    Under Your Skin
    Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
    Fighting Germs
    Your immune system protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs. What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.

    阅读下列短文，根据短文中的信息完成文后表格。（每空一词)
    In the past, man did not have to think about the protection of his environment. There were not many people on earth, and natural resources seemed to be unlimited.
    Today, things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue like this, human life on earth will not survive.
    Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.
    We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste products are still put into rivers or into the sea, and there are few laws to stop this.
    We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.
    What can we do to solve these problems?
    If we eat more vegetables and less meat, we will easily get more food. Land that is used to grow crops can feed five times more people than land where animals are kept.
    The world population will not rise so quickly if people use modern methods of birth control.
    Finally, if we educate people to think about the problems, we shall have a better and cleaner living place in the future.

    Problems

    Clean water is not only important for people to produce food, but necessary for our life. However, many people in Asia and Africa don’t have enough clean water to use. The World Health Organization reports that almost 4,000 children die each day of dirty water or lack of water.
    Farmers use 70%~85% of the world fresh water to produce food. People usually don’t pay much attention to how much water industry (工业) uses, but you may be surprised to know that industry uses 59% of the water in developed countries.
    Home use takes up only 8% in the world. But as cities grow, more water will be used. The local government has to try to make people use less water.
    In 60% of European cities, people are saving water by using less. They even keep waste water for other use.
    In Australia, the government has encouraged people to collect rainwater and recycle water from showers for a second use.
    The US Environmental Protection Agency has made a water saving program to encourage families and businesses to check their water use and save more water. Scientists and the UN are looking for good water management as the key to solving the problem. We can all work together to protect our fresh water in our daily life.
