Germs are very small living things. They are ...

Germs are very small living things. They are so small that we cannot see them unless we use a microscope. They are found in all kinds of places, all over the world. There are four main types of germs that they can invade (侵入) plants, animals and people, and sometimes they can make us sick.　

Bacteria (细菌) live just about everywhere on earth. Not all bacteria are bad. Some of them are good for our bodies. They help us keep things in balance. Good bacteria live in our bodies and help us use the nutrients in the food we eat and make waste from what's left over. We couldn't make the most of a healthy meal without these important helper germs! On the other hand, there are several types of bad bacteria, including those that cause sore throats.

Viruses (病毒) need a host to keep living. They need to be inside a place of a living plant or animal, including humans, or even inside a bacterium! Whatever a virus lives in is called its host. Once a virus finds the perfect host, the goal is to reproduce and spread. Viruses are pretty tricky because they can change quickly to fit a new environment. When viruses get inside people's bodies, they can spread and make people sick.

Fungi (真菌) are kind of like plants. Unlike other plants, fungi cannot make their own food from soil, water, and air. Fungi love warm and wet places. Most fungi are harmless. The kind that can grow on your skin can be treated. It probably won't hurt you. But it really makes you uncomfortable!

Protozoa (原生动物) are extremely small. Most of them live in water. Some protozoa actually eat bacteria and they are good because they also eat the waste of other small living things. Some protozoa are bad, and they live off of other living things, sometimes humans. For example, if a person drinks unclean water, protozoa may cause health problems.

Tiny plants and animals live all around us. We cannot see them because they are so small, but they are everywhere.

They live in the soil, the air, and in rivers and oceans. They grow on mountains and in caves. Some live in the ice at the north and south poles; some live where it is very hot. They are found throughout cities and in the country. They grow on other plants and animals. Some are even living on you, on your skin, hair, and inside your body, in your mouth, nose, and all through your intestines (肠).

These tiny plants and animals are called microbes. The word microbe is made from two other words: micro, meaning small, and bios, meaning life. So, microbe means small life.

Microbes have been on earth for a very long time. They may have been the first forms of life to be alive. Today there are more microbes in the world than all other living things.

People did not know microbes had existed (存在) long. They were too small for them to see.

But people did see many changes in their world—important changes. And they did not know what caused them. They saw food that they kept too long change color and begin to smell bad. They saw cuts and wounds grow red and painful and become infected. They saw old plants and leaves and trees crumble apart on the forest floor and disappear into the soil. Such changes were a natural part of the world, but people did not understand them. They did not know these changes were evidence (证据) of tiny plants and animals growing all around them.

1.Where do microbes live?

A. Only in the forest.,　　 B. Almost everywhere.

C. Most in very hot areas.,　　 D. Most in rivers and oceans.
