When you close your eyes and try to think of the shape of your own body, what you imagine (or, rather, what you feel) is quite different from what you see when you open your eyes and look in the mirror. The image you feel is much vaguer than the one you see. And if you lie still, it is quite hard to imagine yourself as having any particular size of shape. When you move, when you feel the weight of your arms and legs and the natural resistance of the objects around you, the "felt image" of yourself starts to become clearer. It is almost as if it were created by your own actions and the sensations they cause. The image you make for yourself has rather strange proportions: certain parts feel much larger than they look. If you poke your tongue into a hole in one of your teeth, it feels enormous; you are often surprised by how small it looks when you inspect it in the mirror. But although the "felt image" may not have the exact shape you see in the mirror, it is much more important. It is the image through which you recognize your physical existence in the world. In spite of its strange proportions, it is all one piece, and since it has a consisent right and felt and top and bottom, it allows you to locate new sensations when they occur. It allows you to find nose in the dark, scratch itches and point to pain. If the felt image is damaged for any reason—if it is cut in half or lost, as it often is after certain strokes which wipe out recognition of one entire side—these tasks become almost impossible. What is more, it becomes hard to make sense of one’s own visual appearance. If one half of the felt image is wiped out or injured, the patient stops recognizing the affected of his body. It is hard for him to find the location of sensation on that side, and, although he fells doctor’s touch, he locates it as being on the undamaged side. He loses his ability to accept the affected side as part of his body even when he can see it. If you throw him a pair of gloves and ask him to put them on, he will only glove one hand and leave the other bear. And yet he had had to use the left hand in order to glove the right. The fact that he can see the ungloved hand doesn’t seem to help him, and there is no reason why it should. He can no longer reconcile what he sees with what he feels—the ungloved object lying on the left may look like a hand, but, since there is no felt image corresponding to it, why sould he claim the object as his The "felt image" is much more important because it helps you to be more confident.

M: Do you think women are generally better at certain things than men W: Well, it seems to me women are much better at dealing with more than one thing at a time. I don’t know whether this has to do with the difference in their brain or whether it’s just how they have to cope more often with more than one thing. For example, it is usually women who work, have babies, look after the babies and take the main responsibility for looking after the home. And maybe it’s practicing all that makes women be better able to do more than one thing at a time. Men, it seems to me, can only concentrate on one thing at a time, including boring domestic things like washing the dishes, If a friend of mine who is a man washes the dishes he’ll find it quite difficult to conduct a conversation at the same time, whereas if I’m doing the dishes I’m always talking to someone, probably cooking something as well, and finding that not too stressful. M: Do you think women are more interested in personal relationships than men W: Generally, yes, though again I don’t know if this is because that from an early age they are taught to please other people, whereas men are always taught to please themselves. I think relationships are more central to most women’s lives. For example, I think men don’t have very good conversations with each other, whereas women do. If you listen to women talking, often they will be having, after a relatively short time of knowing each, fairly personal and truthful conversations, whereas men have conversations not about what I’d call real things. They will talk about their work in a very superficial way, or their interests in a very superficial way, for example, and football is, just a sort of way for men to relate to each other without actually saying anything important, it appears to me. What do we know about the difference between men and women in terms of personal relationships()
A. It is easier to get along with women than with men.
B. Women tend to reveal their feeling more easily.
C. Personal relationships are more central to most men’s lives.
D. It’s easier to establish personal relationships with women than with men.

A. Because women have better abilities.
Because men are not used to housework.
C. Because men lack practice.
D. Because men find it easy to concentrate on only one thing.
All of us who work in television news are constantly being accused of emphasizing the negative side of everything. We get letters saying we never cover a story unless something terrible happens. Tonight, we’ve put together a little news broadcast, to give you an idea of what it would look like if you had it your way. "O’ Hare Airport in Chicago is one of the nation’s busiest. At 11 a. m. , a jet aircraft with 168 passengers and ten crew members on board started down the long runway. The plane, headed for London, took off without incident. It landed without incident too. Everyone on board is now in London. " "For a report from New York City we take you to our correspondent standing in front of the Rose Plaza, one of New York’s most luxurious hotels. CBS News has learned that last evening, after a night on the town, the Shah of Franakanpan and his semi-beautiful wife returned to their hotel suite after depositing more than a million dollars’ worth of jewelry in the hotel safe. The jewelry included the famous Cooch Behar Diamond. " "This morning, when the safe was opened, all the jewelry including the famous Cooch Behar Diamond was right there where they’d left it." "In Florida, the orange crop was hit by another night of average weather. The oranges just hung there and grew. " "The oil tanks behind me are very close to a residential area. If they were on fire, smoke would be seen billowing up for miles around. They aren’t on fire though; they are just sitting there. " And if that’s what you want to hear, that’s the way it was. Th fallacy the author makes in the passage is ().
A. to emphasize the negative side of everything
B. to let the letter senders have it in their way
C. to call plain and ordinary things "good news"
D. to give examples of "good news" to counter make fun of the letter sender
