Owning Books

We enjoy reading books that belong to us much more than if they are borrowed. A borrowed book is like a guest in the house; it must be treated with

D．By earth.

enough careful attention. You must see that it keeps no dirty or destroyed pages.

But books are for use, not for show; you should own no book that you are afraid to mark up, or afraid to place on the table, wide open and face down. A good reason for marking favorite passages in books is that this practice enables you to remember more easily the important sayings, to refer to them quickly, and then in later years, it is like visiting a forest where you once walked in.

Everyone should begin collecting a private library in youth; this habit can here be developed with every advantage. The best wallpaper is books; they are more varied in color and appearance than any wallpaper, they are more attractive in design, and if you sit alone in the room in the firelight, you are surrounded (包围) with close friends. The knowledge that they are there in common thought is both encouraging and refreshing. Books are of the people, by the people, for the people. They are part of history; the best part of personality.

Book – friends have this advantage over living friends; you can enjoy the most truly great society in the world whenever you want it. The great dead are beyond our physical (身体的) reach, and the great living are usually almost as too far to reach. But in a private library, you can at any moment talk with Shakespeare or Carlyle or Dumas or Dickens. And there is no doubt that in these books you see these men at their best. They ―laid themselves out‖ they did their best to entertain (娱乐) you, to make a favorable impression. You are necessary to them as an audience is to an actor; only instead of seeing them masked, you look into their inside heart of heart.

48. The underlined word

A. expectation

B. admiration

C. great care

D. nice view

49. The writer’s attitude towards books is like _________.

A. walking into an old forest B. treating a guest in the house C. showing out a private library D. talking to great dead and living

50. The best wallpaper, according to writer, is _______ .

A. colors B. books A. easy

D. Get it free!

 Have you ever been to Shanxi in north China?

 Would you like to see for yourself the different cultures in Shanxi?  Do you want to experience the Yellow River culture of China?

Shanxi is one of the important places of Chinese culture and described as the place of origin (起源) of ancient China.

It is proud of the great Taihang Mountains, the Yellow River the thousand - old Chinese culture, Mount Wutai, which is seen as four mountains by Chinese Buddhists (佛教), the Yungang

The tail

It began as the worst summer of my life. The evening before the first day of summer vacation, my mother broke the to me.

―Nancy, your father and I decided that you’re old enough now to take on certain responsibilities. You need to look after Jackie for this summer.‖

1

B. when they built the hospital

C. when do they build the hospital D. when they build the hospital

―Not that, Mom! That’s not fair. All summer with Jackie! I won’t be able to play with my friends.‖ ―Life isn’.‖

I knew she would say that. Jackie is my seven-year-old brother and has been following me like a tail .I’d rather be in school rather than minding Jackie all day.

―You’ll still be able to play with your friends,‖ she continued, ―but Jackie comes first. He is your ’re a family and we all have to help out.‖

Jackie turned up and raised his right hand. ―I promise to do whatever Nancy says.‖

When I was out jumping ropes for the summer competition, he was there in front of me. When I was riding bikes with friends, he was there, too. ―Jackie, you’re not going to be in our faces all day,‖I shouted at him.

―Mom said you have to me, so I have to be in your face.‖

Later on, my friends and I decided to climb the hills which mom had warned me not to do. We were afraid that Jackie would tell mom the 捉迷藏) in the park. But in fact, we went to the hills leaving Jackie behind. When we came back in an hour, Jackie was nowhere to find. We checked everywhere in the park, back at home, all the corners of the street …

―Jackie!‖I cried, ―You’re my only baby brother. Dear God, please let me find him. I’ll play any game he wants. I’ll never lie to him ...‖

Suddenly, we heard some sound up above a big tree. When we looked up, Jackie was there laughing at us. ―of finding me, yeah? ‖ ...

―Everything’s OK, Nancy? Nothing happened?‖ Mom asked me when she came back from work. ―No, mom.Everything is fine. Nothing happened at all.‖ Jackie shouted.

Well, the summer didn’t turn out to be so after all. My parents both got pay rise, me and my friends won the rope – jumping competition,

and I’d play a game with Jackie or read him a story. And Jackie never told my parents that I’d lost him. I found out that you miss a tail until you almost lose it.

There was once a little girl named Molly. Her dad was good at gardening. Everyday, he worked in a small garden at the back of their house. Molly would quietly watch her dad working in the garden. She wondered how the little seeds (种子) grew into seedlings and those into big plants. The beautiful colors of flowers and fruits made her excited. ―When I grow up, I shall work in the garden like dad,‖ she would think.

Then one day, dad brought her some books, notebooks, pencils, and an eraser because she would go to school soon. Molly had seen her elder brother sharpening(削) his pencil everyday. Every time he sharpened the pencil, it looked smaller. And his eraser also became smaller because he used it everyday.

Suddenly, she had an idea. Why not plant a pencil and an eraser

as dad planted the roses? Molly filled a flowerpot (花盆) with earth. She stuck a pencil in it, with the sharpened end pointing upwards. She fixed the eraser on the top of the pencil. How surprised everyone would be when her pencil and eraser started growing! She hid her pot behind tall plants.

Molly watered her pot daily. Everyday she would look carefully for signs of growing. She wondered why her pencil and eraser did not grow.

One day she asked her dad, ―Why is my plant not growing, dad?‖ ―What plant?‖

Molly showed him her pot with the pencil and the eraser stuck on it. Dad laughed and said, ―My little girl, pencils and erasers don’t grow on their own. They grow in you. When you go to school, you’ll understand and feel their growing inside you!‖

―Then what flowers will they grow inside me?‖ ―That’s up to you! They’ll grow in the way you’d like!‖

44. Where did Molly’s dad work every day?

A．In a small school. B．In a small garden.C．In a small house.D．In a small park. 45. What did her dad bring to her?

A．Some story books, pencils, and an eraser． B．Some books, notebooks, and a ruler． C．Some notebooks, pens, and an eraser． D．Some books, pencils, and an eraser．

Owning Books

We enjoy reading books that belong to us much more than if they are borrowed. A borrowed book is like a guest in the house; it must be treated with , with enough careful attention. You must see that it keeps no dirty or destroyed pages.

But books are for use, not for show; you should own no book that you are afraid to mark up, or afraid to place on the table, wide open and face down. A good reason for marking favorite passages in books is that this practice enables you to remember more easily the important sayings, to refer to them quickly, and then in later years, it is like visiting a forest where you once

walked in.

Everyone should begin collecting a private library in youth; this habit can here be developed with every advantage. The best wallpaper is books; they are more varied in color and appearance than any wallpaper, they are more attractive in design, and if you sit alone in the room in the firelight, you are surrounded (包围) with close friends. The knowledge that they are there in common thought is both encouraging and refreshing. Books are of the people, by the people, for the people. They are part of history; the best part of personality. Book – friends have this advantage over living friends; you can enjoy the most truly great society in the world whenever you want it. The great dead are beyond our physical (身体的) reach, and the great living are usually almost as too far to reach. But in a private library, you can at any moment talk with Shakespeare or Carlyle or Dumas or Dickens. And there is no doubt that in these books you see these men at their best. They ―laid themselves out‖ they did their best to entertain (娱乐) you, to make a favorable impression. You are necessary to them as an audience is to an actor; only instead of seeing them masked, you look into their inside heart of heart.

48. The underlined word

A. expectation

B. admiration

C. great care

D. nice view

49. The writer’s attitude towards books is like _________.

A. walking into an old forest B. treating a guest in the house C. showing out a private library D. talking to great dead and living

50. The best wallpaper, according to writer, is _______ .

A. colors B. books

D．By earth.

C. library D. friends

Some people think only school children do not agree with their parents, however, it is not true. Communication is a problem for parents and children of all ages. If it’s hard for you to communicate with your parents, don’t worry about it. Here are some advice for you to bridge the generation gap

Don’t argue (争辩) with your parents. Don’t get to your parents when you are angry. Your parents probably won’t consider your ideas if you are shouting at them. And you can’t express yourself well if you are angry. Go someplace to unhappy. Then think about what you want to say to your parents. If you don’t think you can speak to them at the moment, try writing a letter.

Try to reach a compromise (和解). Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. Michael’s mother didn’t agree with him about buying a motorcycle. They argued over it. But they finally came to a compromise. Michael bought the motorcycle, but only drove it on certain days.

Of course, your parents might refuse to compromise on something. In these situations, it is especially important to show love and respect (尊敬) to them. Showing respect will keep your relationship strong.

Talk about your values. The values of your parents are probably different from those of your own. Tell your parents what you care about, and why. Understanding your values might help them see your purposes in life.

A good relationship with your parents can make you a better and happier person. It is worth having a try!

50. The passage tells us _______ have a communication problem. A. parents and other people B. school kids and their parents C. teachers and their students D. parents and children of all ages 51. The underlined phrase “

A. to make yourself happy B. to get you quiet and relaxed C. to have a good rest D. to hide yourself quickly 52. From the passage we learn that _______.

A. parents and children should not have a generation gap B. parents should show love and respect to their children C. there are some good ways to bridge the generation gap D. there are so many serious problems in families today
