FoodThe U. S. food supply is the most varied and abundant in the world. Americans spend a smaller share of their disposable income on food than citizens of any other country and choose from an average of 50,000 different food products on a typical outing to the supermarket. In 1994, the fowl supply provided an estimated 3,800 calories per person per day, enough to supply every American with more than one and a half times their average daily energy needs. Given this abundance, few of the Nations resources have traditionally been devoted to measuring or reducing food waste.In recent years, growing concern about hunger, resource conservation, and the environmental and economic costs associated with food waste have raised public awareness of food loss. This in turn has accelerated public and private efforts to make better use of available, food supplies by recovering safe and nutritious food that would otherwise be wasted.Of course, not all food that is lost is suitable for consumption. Some losses like the condemnation of diseased animals at the slaughtering house (屠宰场), or the discard of rotten fruit from the produce shelf at the supermarket are necessary to ensure the safetyand health of the U. S. food supply. Such foods are not recoverable for human use.Likewise, plate fragments are appropriately discarded at eating establishments out of health considerations. In addition, not all food that is lost is economically recoverable. Food recovery efforts are often limited by financial restraints that make it difficult to match recovered food with potential recipients.Nevertheless, large quantities of healthy, edible food are lost at every stage of the marketing system. Example of such losses include meats, bread, and other foods prepared by a restaurant or hotel but never served and the discard of defected or over-ripe .produce, which maybe difficult to sell out for some reasons, but are otherwise nutritious and safe. The author’s attitude towards the condemnation of diseased animals is reasonable.()
Youth Emancipation in Spain The Spanish Government is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest. Around 55 percent of people aged 18-34 in Spain still sleep in their parents’ home, says the latest report from the country’s state-run Institute of Youth. To coax(劝诱) young people from their homes, the Institute started a "Youth Emancipation(解放)" programme this month. The programme offers guidance in finding rooms and jobs. Economists blame young people’s family dependence on the precarious(不稳定的)labour market and increasing housing prices. Housing prices have risen 17 percent a year since 2000. Cultural reasons also contribute to the problem, say sociologists(社会学家). Family ties in south Europe—Italy, Portugal and Greece—are stronger than those in middle and north Europe, said Spanish sociologist Almudena Moreno Minguez in her report "The Late Emancipation of Spanish Youth: Key for Understanding". "In general, young people in Spain firmly believe in the family as the main body around which their private. life is organized," said Minguez. In Spain— especially in the countryside, it is not uncommon to find entire groups of aunts, uncles, cousins, nieces and nephews(外甥/侄子) all living on the same street. They regularly get together for Sunday dinner. Parents’ tolerance is another factor. Spanish parents accept late-night partying and are wary of setting bedtime rules. "A child can arrive home at whatever time he wants. If parents complain he’ll put up a fight and call the father a fascist," said Jos6 Antonio Gomez Yanez , a sociologist at Carlos III University in Madrid. Mothers’ willingness to do children’s household chores(家务) worsens the problem. Dionisio Masso, a 60-year-old in Madrid, has three children in their 20s. The eldest, 28, has a girlfriend and a job. But life with mum is good. "His mum does the wash and cooks for him; in the end, he lives well," Masso said. Which of the following statements is NOT true of Dionisio Masso

就重量而言，多种不同的人工制甜剂的混合物在效果上与任一单一制甜剂相同。当用于制甜食物时，混合物极大地降低了消费者摄入过量的单一制甜剂的可能性。因此，混合物应当被使用，而不是单独使用单一的人工制甜剂。因为混合物明显地更健康，并且同样有效。 上面论述依赖下面哪一个假设( )
