[问答题]

根据下面资料，回答Germs 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. Your immune system (免疫系统) 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. What do antibodies do?
