题目内容

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(蚊子), carry dangerous germs. These germs cause headaches(头疼), 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(进入) your body when you touch your eyes, nose, or mouse.
Fighting Germs
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(肥皂) and water. Soap kills many germs, and water washes them away.

Have you ever been ill? When you are ill, you must be unhappy because your body becomes hot, and there are pains all over your body. You don’t want to work, and you stay in bed, feeling very sad.
What makes us ill? It is germs(细菌). Germs are everywhere. They are very small and you can’t find them with your eyes, but you can see them with a microscope(显微镜). They are very very small and there could be hundreds of them on a very small thing.
Germs are always found in dirty water. When we look at dirty water under the microscope, we shall see them in it. So your father and mother will not let you drink dirty water.
Germs can be found not only in water but also in air and dust(灰尘). If you cut your finger, if some of the dust from the floor goes into the cut(割开处), some of the germs would go into your finger. Your finger would become big and red, and you will have much pain in it. Sometimes the germs would go into all of your body, and you would have pain everywhere.
【小题1】Which of the following is true?

A．If things are very very small, they are germs.

B．If things can’t be seen, they must be germs.

C．Germs are only in dirty water.

D．Germs are everywhere around us.

【小题2】Why don’t your parents let you drink dirty water?

A．You haven’t looked at it carefully.

B．Water can’t be drunk in this way.

C．There must be lots of germs in it.

D．Water will make you ill.

【小题3】What’s the main idea of the passage?

A．Germs may make us ill.

B．Germs are in dirty water.

C．Don’t drink dirty water.

D．Take care of your fingers.

When you cough or sneeze(打喷嚏), please turn your head away from others and cover your mouth with the full part of your hand. Afterwards, you should say, “Excuse me.” This is a rule I set for my students. It is so simple, but many kids have never been told to do this. In fact, I noticed adults cough and sneeze in public without putting a hand over the mouth. I hate traveling by subway in New York during cold and flu season, because it is certain that someone is going to stand right behind me and cough or sneeze on my neck.

One important thing I point out to the kids is that after they sneeze or cough on their hand, they should wash their hands as soon as possible. Otherwise, they will be passing those germs(细菌) along to everything and everyone they touch. In order to help the kids remember this rule, I tell them about an old story. It says that when you sneeze, evil spirits jump into your body. If you don’t cover your mouth, the spirits will enter, but if you cover your mouth, you will keep them out. We say “God bless you” when someone sneezes, and in Germany you should say “Gesundheit.” That means “Good health to you.” Both expressions are said—just in case you didn’t cover your mouth in time and the spirits were able to enter your body. The kids love finding out the origins(起源) of these expressions and it encourages them to put advice to use more often.
