“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 is 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. There you can feel everything on show. If we want to see better, reach out and touch. Then you will really see. By touching things,________.
| A．you will have a strange feeling |
| B．you will learn how to reach out your hand |
| C．you can tell the difference of the things |
| D．you can tell what colors they are |

Not very long ago, a special family system(体系) existed in certain parts of South India. In the system, the actual head of a family unit was the mother’s eldest brother, though the mother also had an important position in the family. In families of this kind, a husband was actually no more than a visitor. He did not live with his wife, but with his own mother, brothers and sisters in another house. He saw his sons and daughters sometimes, but the man who actually fed and cared for them and acted as their father was their uncle--- their mother’s brother.
But this system, in which brothers and sisters take the place of the father, no longer exists in South India except in a few villages. Economic(经济的) changes have had far- reaching effect on family life. Family life began to change when men went out to work in factories and offices instead of working with their mothers, brothers, and sisters on the land. When a man went out to work, he had money of his own and could buy his own land and build his own family, instead of depending on his mother and his brothers. He wanted to be independent(独立的). This is an example of the way in which economic relations can have an effect on family relationships. The best title of this passage is ______.
| A．Husband Actually Visitor in Family |
| B．Family System in South India |
| C．Wife Has Important Position in Family |
| D．Economic Relations Affects Family Relationships |
Who had the actual control of a family in South India not long ago?

| C．very few families | D．not any families |
Life gets noisier every day. Very few people can be free from noise of some sort or another. It doesn’t matter where you live, in the middle of a modern city, or a faraway village--- the chances are that you’ll be disturbed by jet aeroplanes, transistor radios, powered engines, etc. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they’re working.
Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud and this can do harm to their eardrums(耳鼓). The noise level in some discos is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration(专心) suggested that although a lot of people say that any noise disturbs their concentration, what really influences their ability to concentrate is a change in the level of noise. It goes on to say that a background noise which doesn’t change too much (music, for example) may even help people to concentrate.According to this passage, the noise pollution______.
| A．has become the worst in the countryside | B．has become better in big cities |
| C．has spread from cities to villages | D．has been controlled in modern cities |
What does background music refer to?
| A．Music played while people are working. |
| B．Music played in the backyard. |
| C．Noise that continues while you’re listening to other noises. |

Some people have their hearing harmed______.
| A．while listening to pop music | B．in complete silence |
| C．when speaking loudly | D．while watching TV |
Which of the following isn’t included among the things causing noise?
| A．Rivers | B．Transistor radios |

| A．all kinds of noise | B．great changes in the level of noise |

I was in lodgings (寄宿处) now, on my own, but the other lodgers had constant visitors up and down the stairs past my door. None of this disturbed me except one girl who sang softly to herself an old Russian folk song as she ran up to the room above. It was a sound of sweetness, musical, soft, unselfconscious and happy. I began to listen out for it, jumped up from my table, and threw open the door to catch a glimpse(一瞥) of her as she passed, but I was always too late. I asked the people upstairs who she was, and described the beautiful sounds she made. They became rather reserved(拘谨) and exchanged glances and hurriedly admitted it might be Sally. I thought she was someone special, not to be discussed in the ordinary way, and became a little curious to meet her. But the last thing I wanted at that stage was to get caught up with anybody. I’d just come to the end of a rather painful friendship, and now I had work to do.
One day, I came face to face with a girl on the landing. It was certainly her; whoever made that noise would look as she did. We stood and stared at each other too long for comfort. I broke the moment and, excusing myself, moved past her because it was too like the movies. I thought for some time of that long, silent stare, and laughed. She was tall and looked proud, with a slight , round-shouldered look that made me breathless and I didn’t know why.At his lodgings, the author __________.
