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，you stay in bed，feeling very sad.
　　What makes us ill? It is germs(細(xì)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. They are 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 aren't found only in water. They are found in air and dust. If you cut your finger，if some of the dust from the floor goes into the cut(割開處)，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.

Reading comprehensionA. Choose the best answer. (12分)

Letter A
To the Editor:
Why do our children have 11 weeks of summer vacation? Many years ago, 85 percent of Americans worked on farms. Children needed summer vacation because they helped with the farm work. Today only 3 percent of Americans work on farms. But our children still have long summer vacations.
American students lose one or two months of learning during their summer vacations. Away from school for so many weeks students forget what they learned. Experts say that students lose maths skills and reading skills. At the beginning of school in September, teachers have to review last year’s studies for the first four to six weeks of school.
Summer vacations are not great opportunities for learning. Most parents work outside of the home. They can’t be with their kids during the long summer months. Some families can pay for summer camps, but many can’t. Most children stay home and watch TV. They are bored. Most children do not learn new skills during the summer.
James, Teacher
    Letter B
To the Editor:
I am against a longer school year. I believe people learn everywhere, not just in school. I believe children gain experience in the world. Summer vacation is a great opportunity. Kids can discover the world outside of school. They can learn to do things they can’t learn in a classroom. They can learn to swim and ride bikes. They can travel or go to summer camps. They can take time to do things like cooking and art. Some can get summer jobs. They can get work experience or help people in the community. They can spend time with people of other ages. Basically, they can get more experience in the world.
Long summer vacations give families time together. During the school year, everyone is busy. During summer vacations, we take time to do things together. Vacations are good for families.
Linda, Parent

When we can see well, we do not think about our eyes often. It is only when we can not see perfectly that we come to see how important our eyes are.
People who are nearsighted can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing and reading, become nearsighted. Then they have to wear glasses in order to see distant things clearly.
People who are farsighted face just the opposite problem. They can see things that are far away, but they have difficulty reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses too.
Other people do not see clearly because their eyes are not exactly the right shape. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
When night falls, colors become fainter to the eyes and finally disappear. After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers. Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head in its direction. This is because when you turn your head, you are looking at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they can not see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark.
小題1:We don’t know that our eyes are of great importance until ________.
A．we think about our eyes
B．we cannot see clearly
C．we wear glasses
D．we have to do much reading
小題2:According to the passage, a ________ is more likely to be nearsighted.
A．tailorB．doctorC．guardD．painter
小題3:People who are farsighted ________ .
A．cannot do a lot of close work without glasses
B．can only see things that are very close to their eyes
C．have difficulty reading a book if they hold it at arm’s length
D．have the same problem as the nearsighted people
小題4:To see a small thing at night, it is better to look ________ .
A．with wide open eyes
B．with half shut or narrowed eyes
C．straight at it
D．in a slightly different direction
