    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(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.

    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.

    科目：初中英语 来源：2013-2014学年江西省抚州市九年级上学期期中考试英语试卷（解析版） 题型：阅读理解

    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.

    1.The writer of this article must be _________.

    A. a reporter        B. a teacher        C. a doctor          D. an officer

    2.What does the underlined word “this” mean?

    A. Don’t cough or sneeze in front of people.

    B. Don’t stand beside someone who coughs or sneezes.

    C. Many people cough or sneeze on the underground train.

    D. Cover your mouth when coughing or sneezing and say sorry.

    3.After coughing or sneezing on their hand, students are advised to _________.

    A. say “God bless you” immediately

    B. wash their hands as soon as possible

    C. go to see a doctor as soon as possible

    D. go home and have a good rest

    4.According to the article, the writer would like the kids _________.

    A. to be polite to adults                B. to be in better health

    C. to have good manners               D. to do well in exams
