Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet. In rejecting exercise, some people may be discouraged too much by caloric-expenditure charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry . Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports. Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight. If you have been sedentary   and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight. "Even exercise professionals accept half a point here" means "They  _  ". A) agree that the calories in a small piece of pastry can be easy to work off by exercise B) partially believe diet plays a supporting role in weight reduction C) are not fully convinced that dieting can help maintain one's new weight D) are not sufficiently informed of the positive role of exercise in losing weight

Many years ago in a small German town, a Jewish businessman had the misfortune of owing a large sum of money to the moneylender. The moneylender, who was old and ugly, fancied the businessman's beautiful daughter. So he proposed a bargain. The moneylender told them that he would put a black pebble and a white pebble into an empty bag. The girl would then have to pick one pebble from the bag. If she picked the black pebble, she would become the moneylender's wife and he would _ her father's debt. If she picked the white pebble, she need not marry him and her father's debt would still be forgiven. But if she refused to pick a pebble, her father would be thrown into jail. They were standing on a pebble-strewn path. As they talked, the moneylender bent over to pick up two pebbles. The sharp-eyed girl noticed that he had picked up two black pebbles and put them into the bag. He then asked the girl to pick a pebble from the bag. No doubt she was caught in a dilemma. What would you have done if you were the girl? Careful analysis would produce three possibilities: 1.The girl should refuse to take a pebble. 2.The girl should know that there were two black pebbles in the bag and expose the money-lender as a cheat. 3.The girl should pick a black pebble and sacrifice herself in order to save her father from his debt and imprisonment. The above story is used with the hope that it will make us appreciate the difference between lateral  and logical thinking. Read on... The girl put her hand into the moneybag and drew out a pebble. Without looking at it, she fumbled and let it fall onto the pebble-strewn path where it immediately became lost among all the other pebbles. "Oh, how clumsy of me!" she said. "But never mind, if you look into the bag for the one that is left, you will be able to tell which pebble I picked." Since the remaining pebble is black, it must be assumed that she had picked the white one. And since the moneylender dared not admit his dishonesty, the girl changed what seemed an impossible situation into an... It can be inferred from the passage that   _  . A) The girl dropped the pebble onto the path on purpose B) The girl dropped the pebble onto the path by accident C) The girl didn't know there were two black pebbles in the bag D) The girl replaced a black pebble in the bag

(Question)
In 1859, prefix = st1 /ItalyandFrancewere at war withAustria, and Henry Dunant, a young Swiss gentleman, came upon one of their battlefields. For the first time in his life, Dunant saw how heartless war would be. Around him were suffering men untended and left to die where they fell. Henry Dunant went to work at once. Helped by several peasant women, he formed an ambulance service and set up headquarters in a little church. He treated the wounds of Frenchmen, Italians and Austrians alike. When he was asked why he did so, his answer showed a spirit of humanity that was not common in those days. "We are all brothers. A wounded enemy is an enemy no longer." With his band of assistants, Dunant helped to save many lives. The "gentleman in white" (as Dunant was called because he wore a white suit) was looked upon by hundreds of wounded men as an angel.     When Dunant returned toSwitzerland, he could not forget the needless suffering on the battlefield. He thought of a great organization that should be planned to include many nations. It would do its work with the approval of all countries. And it must operate under a sign that all would know: its symbol would be a red cross against a white background. He wrote a book to make the public see the need for this great organization. In the book he included a truthful account of what he had seen on the battlefield. The consequence was that readers were shocked by what he described. After Dunant's hard work, in Geneva on October 26, 1863, all the nations of Europe were invited to a meeting at which it was decided a relief society should be formed in each country. Then the Geneva Convention was made the following year. The nations that signed the Geneva Convention chose the red cross as the symbol for the international organization.     Until his death in 1910, Dunant was always ready to look for a noble cause. And when the Nobel Peace Prize was awarded for the first time in 1901, the honor went to Dunant. No man has deserved it more than the founder of the Red Cross. Dunant planned the organization with an intention to   _  . A) function only in Europe B) stop war C) get the approval for relief work from every country D) show his ability
