    We’ve talked about snails（蜗牛） and their slow move. But much of the time snails don’t move at all. They are in their shells —sleeping.
    　　Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
    　　In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers, are very weak. But its sense of smell is very strong. It helps the snail to find food and the new greens.
    　　A snail’s mouth is no bigger than the point of a pin. Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.

    This March, the H7N9 virus hit Zhejiang, Shanghai, Anhui, Jiangsu and so on. It seemed that most people who were infected（被感染）with H7N9 had the common flu. Some people suffered from a fever or a cough.
    Don’t be afraid---it’s not easy to be infected with the virus. Here is some advice to help you protect yourself when it comes.
    Wash your hands. You need to wash your hands with soap and hot water before you eat, after you use the toilet , and after you touch animals, because your hands may carry viruses.
    Cover your nose and mouth, when someone sneezes（打喷嚏）or coughs, flu viruses can travel as far as one meter through the air, so you’d better stand a proper distance while talking to someone who has a cold. And always cover your nose and mouth with a piece of paper when you sneeze or cough, and then clean your hands.
    Wear a mask（口罩）. Some doctors say that masks can stop the flu as much as 80%, but if you don’t wash your hands often, it’s no use wearing a mask. And it’s necessary to wear a mask in the groups of people.
    Do sports often. Exercise will help your body strong enough to resist the virus.
    小题1:How many ways to stop the virus are mentioned in the passage?
    A．ThreeB．FourC．FiveD．Six
    小题2:What does the underlined word “resist” mean in Chinese?
    A．抵抗B．传播C．感染D．治愈
    小题3:Which of the following is TRUE according to the passage?
    A．Some people who were infected with the H7N9 virus had a toothache.
    B．You should cover your mouth and nose with a piece of paper when you sneeze or cough.
    C．Some doctors say that washing your hands can stop the flu as much as 80%.
    D．It’s easy to be infected with H7N9 virus, so you mustn’t go to the places with groups of people.
    小题4:What’s the main idea of this passage?
    A．It tells us how to wash hands.
    B．It tells us why we should use masks.
    C．It tells us we should do more exercise to be strong.
    D．It gives us some advice on how to protect ourselves when the H7N9 virus comes.

    I often hear some students say English is difficult, and it gives them a headache. So they can't learn it well. But English is very easy for me. I'm good at it. I'm very glad to tell you something about how I study English.
    First, I think an interest in English is very important. When I was in Grade One, we had a new subject-English. It was fresh for me. I was interested in it, so I worked hard at it. Soon we had an English exam and I got a very good mark. How happy I was! After that, I learned English harder and harder. Our English teacher often teaches us English songs, the songs sound nice. I often think how interesting English is!

    Besides this, I often read English stories, jokes and easy novels. From these I know English is not only interesting, but also useful. They help me understand a lot of things. So to do more reading is an important way to learn English well.
    And I also do some exercises from our class magazines, and I often write English diaries. English has become a close friend of mine.
    Now I have learned English for more than two years. I always keep the first position in our school. From these words, I hope every student can learn English well.

    When you cough(咳嗽) or sneeze, 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 notice adults cough and sneeze in public without putting a hand over the mouth. I hate traveling by underground in New York during cold and flu(流感) 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 along to everything and everyone they touch.
    In order to help the students 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(德国) you should say "Gesundheit". That means "Good health to you." Both expressions are said that if 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 encourage them to put the advice to use more often.
    小题1:The writer of this article must be _______ .

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

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