If you are writing or studying, it makes much difference where the light comes from. People use        and pens every day. They have to be very careful about the way of the light because the light shines on their work.
Every        gets its light either from daylight        the window        from the lamps or electricity,        no matter what kind of light it is, the way it shines towards our books or work is very important to the eyes.
Take a book and sit with your        toward the window, and try to read. Your shadow(影子) falls all over the page and makes it        for your eyes as if you were in a        room.
Now turn around and face the window. The page is        shadow again, while the bright light is in your eyes.
Try sitting with your        side toward the window. This is very good for        , but if you were writing, the shadow        fall across the page and bother you        .
There is another way – sit        your left side to the window. Now everything is perfect for writing as well.
Whatever kind of light is in the room, the rule about the right way to sit is        the same.

“If you want to see a thing well, reach out and touch it!”That may seem a strange thing to say. But touching things can help you to see them better. Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth* and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins*  in your pocket. You can feel a little drop of water on the back of your hand, too.

All children soon learn what “Don’t touch!” means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things as we might buy: food, clothes. To see something well, we have to touch it.

There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!

Most museums are just for looking. But today some museums have some things to touch. Their signs say, “Do touch!” There you can feel everything on show. If we want to see better, reach out and touch. Then you will really see!

All the wisdom of the times, all the stories that have delighted mankind for centuries, are easily and cheaply available to all of us in books, but we must know how to make use of this treasure. The unluckiest people in the world are those who have never discovered how satisfying it is to read good books.

I’m very interested in people and finding out about them. Some of the most amazing people I’ve met could only  be found in a writer’s imagination, then in his book, and then, again, in my imagination. I’ve found in books new friends and new worlds.

Reading is fun, not because the writer is telling you something, but because it makes your mind work. Your own imagination works along with the writer’s or even goes beyond his. Your experience, compared with his, brings you to the same or different conclusions, and your ideas develop as you understand his.

Every book stands by itself, like a one-family house, but books in a library are like houses in a city. Although they are separate(分开的), in some way they are connected with each other. The same ideas, or related(相关的) ones, appear in different places; the human problems that repeat themselves in life repeat themselves in books, but with different solutions(解决方法) according to different writings at different times. Books influence each other. They connect the past, the present and the future and have their own generations (age groups), like families. Wherever you start reading, you connect yourself with one of the families of ideas, and in the end, you not only find out about the world and the people in it, you find out about yourself, too.

Reading can only be fun if you expect it to be. If you concentrate on(专注于) books somebody tells you “ought” to read, you probably won’ t have fun. But if you put down a book you don’t like and try another till you find one that means something to you, and then relax with it, you will almost certainly have a good time — and if you become, as a result of reading, better, wiser, kinder, or more gentle, you won’t suffer during the process.

1.Which of the following ideas may the writer of this article agree with?

A.You will never meet amazing people in your life unless you read.

B.You think actively instead of getting facts passively(被动地)when reading.

C.You will get much delight from any book that you are told to read.

D.You can relax yourself by reading because it involves little thinking.

2.What can we learn from Paragraph 4?

A.We can often find something connected with ourselves in books.

B.Different writings at different times share the same characteristics.

C.The same problems will appear in different books with similar solutions.

D.Reading books which are written for your generation is more helpful to you.

3.What’s the writer’s purpose of writing this article?

A.To advise us to enjoy ourselves by reading.

B.To encourage us to make full use of libraries.

C.To encourage us to find out solutions in books.

D.To advise us to discuss books with other people.
