One day, a poor man, who had only one piece of bread to eat, was walking past a restaurant. There was a large pot of soup on the table. The poor man held his bread over the soup, so the steam from the soup went into the bread, and gave it a good smell. Then he ate the bread. The restaurant owner was very angry at this, and he asked the man for money, in exchange for the steam from the soup. The poor man had no money, so the restaurant owner took him to Nasreddin, who was a judge at that time. Nasreddin thought about the case for a little while. Then he took some money from his pocket. He held the coins next to the restaurant owner's ear, and shook them, so that they made a dingling noise. "What was that?" asked the restaurant owner. "That was payment for you," answered Nasreddin. "What do you mean? That was just the sound of coins!" protested the restaurant owner. "The sound of the coin is payment for the smell of the soup," answered Nasreddin. "Now go back to your restaurant." Why did Nasreddin make a noise with the coins? A) To make the poor man relaxed. B) To pay for the smell of the soup. C) To make the restaurant owner happy. D) To show that he was a rich person.

A few degrees can make a big difference when it comes to food storage. Foods can go bad if they get too warm. But for many of the world's poor, finding a good way to keep food cool is difficult. Refrigerators are costly and they need electricity. Yet spoiled food not only creates health risks but also economic losses. Farmers lose money when they have to throw away products that they can not sell quickly. But in 1995, a teacher in northernprefix = st1 /Nigerianamed Mohammed Bath Abba found a solution. He developed the "Pot-in-Pot Preservation/Cooling System". It uses two round containers made of clay. A smaller pot is placed inside a larger one. The space between the two pots is filled with wet sand. The inner pot can be filled with fruit, vegetables or drinks. A piece of wet cloth covers the whole cooling system. Food stored in the smaller pot is kept from spoiling through a simple evaporation process. Water in the sand between the two pots evaporates through the surface of the larger pot, where drier outside air is moving. The evaporation process creates a drop in temperature of several degrees. This cools the inner pot and helps keep food safe from harmful bacteria. Some foods can be kept fresh this way for several weeks. People throughoutNigeriabegan using the invention. And it became popular with farmers in other African countries. Mohammed Bah Abba personally financed the first five thousand pot-in-pot systems for his own community and five villages nearby. In 2000, the Rolex Watch Company ofSwitzerlandhonored him with the Rolex Award forEnterprise. This award recognizes people trying to develop projects aimed at improving human knowledge and well-being. A committee considers projects in science and medicine, technology, exploration and discovery, the environment and cultural history. Winners receive financial assistance to help develop and extend their projects. The award is given every two years. The next one will be given in 2008. From the text we can infer this article was probably written in _ . A) 1995 B) 2000 C) 2004 D) 2007

Many people feel that their parents were harder on them than on their brother or sister. And many are quick to blame negative results in adulthood on it. But results from a Temple University study published this month suggest that it is not necessarily true. Researchers have found that among siblings in the same family,recalled negative early experiences such as conflicts with parents seem to have little influence over psychological wellbeing in midlife. "Existing research suggests the importance of early childhood parental treatment on later wellbeing,but respondents in this study who thought they were treated less favorably than their siblings have been found to be just as satisfied in their lives,"said Adam Davey,a psychologist in the College of Health Professions. Davey's study looked at data collected from 1,369 siblings between the ages of 26--74 from 498 different families to determine the extent to which different childhood treatment reached into adulthood. Each sibling answered a series of questions about their memories of parental affection ,conflicts with their parents when they were young and current wellbeing. Davey and his team found that those who remembered having more conflicts with their parents than their siblings still tended to have generally high levels of wellbeing in adulthood. Not surprisingly,they also found that happier memories,such as memories of affection and warmth,can have positive effects. Older respondents who were married and had children of their own tended to have a more positive recollection of their childhood. Davey says these findings could suggest that life experience acts as a filter for remembering childhood memories. He adds that personality also plays a role:those who were more outgoing tended to have a better recollection of their childhood. "Even people who grow up in the same environment can have different ways of recalling the past. And it's not necessarily what happens in the past,but the way we remember it that makes a difference to our wellbeing,"said Davey. According to Davey,what influences our wellbeing in adulthood? A) What happened in the past. B) How we remember the past. C) The role we play in society. D) How much we have.
