Americans Eat Out More often and Less Healthfully

Although food cooked at home is far more healthful than meals eaten at restaurants, Americans are dining out more than ever, the U.S. Agriculture Department said Tuesday.Restaurant food accounted for([在数量，比例方面] 占) 39 percent of U.S. meals bought in 1996, up from 26 percent in 1970, the department said in a report, ``Away-From-Home Foods Increasingly Important to Quality of American Diet.'' ``While(尽管)the nutritional quality(营养质量)of foods consumed by Americans has improved overall, foods prepared at home are generally much more healthful than away-from-home foods,'' the department said. ``Despite nutritional gains at home, Americans will find it difficult to improve their diets because they purchase so many meals outside the home,'' the study said. While (尽管)the nutritional content of food prepared both at home and in restaurants has improved in recent years, food eaten out contains more of the nutrients Americans typically(一般地；通常)eat too much of, including fat and saturated fat(饱和脂肪), and less of what is lacking from most diets, such as calcium, fiber and iron. The department recommended nutrition education programs should place more emphasis on teaching U.S. consumers about how to order healthful meals when dining out. Improved diets have been found to prevent risk of heart disease, stroke(中风), cancer, diabetes(糖尿病), osteoporosis-related hip fractures(与骨质疏松症有关的髋关节骨折) and neural tube birth defects(神经管先天缺损). Osteoporosis-related hip fractures cost up to ＄10.6 billion each year in the United States in medical care expenses, missed work and premature deaths(早亡), the department said.

第2题

The future population will be older than today, and this in turn will change the patterns

of social demands. However, Mexico will still be far from the "aging societies" that will most likely prevail (占优势 ) in the industrialized countries. In less than 25 years, the country will have to add almost as much infrastructure as it has already built up to now, simply to maintain services and production at the current levels. This will be a tremendous challenge, although a similar one was faced successfully in the recent past, when available infrastructure was doubled in two decades or so. It is no wonder that much has been said about the need to reduce or preferably halt Mexico's population control which is taken for granted as both good and necessary. It has also gained supporters in the developing world, and Mexico is no exception. But the arguments about population are complicated, as the following discussion illustrates. Even if Mexico's population reaches 125 million by the year 2010, its population density is still smaller than the 1985 population density of some 50 countries. By international standards Mexico will still not be overpopulated by the year 2010. If wealth is generated by people, the more individuals there are, the greater the wealth that potentially could be generated. Why should Mexico control its population at density levels below those of the richer countries if more population represents the possibility of generating more wealth？ On the other hand, it is often pointed out that once sustainability(支撑力) limits are near or are reached, there are decreasing productivity gains (or,perhaps more accurately, increasing productive losses) , and people become a cost rather than an asset. If we assume that there are sustainability limits and that we are close to reaching these limits at a world level, then it is appropriate to check population growth. According to the passage, the population argument is focused on_______.

A.whether more people are a property or a cost

B.whether Mexico should control its population growth or not

C.whether the density of population in Mexico is large or small

D.what the standard international sustainability limit is

Tokyo is World's Priciest City

The weak American dollar and strong European and Asian currencies helped make Tokyo and London the most expensive cities in the world, according to a recent survey. American cities were absent from the top 10, with the most expensive U. S. city, New York, dropping two spots from last year to 12 in the survey of 144 urban areas conducted by Mercer Human Resource Consulting. Moscow ranked in third place, with Osaka, and Hong Kong rounding out the top five most expensive cities.

The survey, drawn up twice a year, ranks cost of living for foreign workers, not local residents, and is used primarily by multinational companies to determine pay for expatriate employees. "The euro appreciated (升值) more than 11 percent in the last six months. " said Marie-Laurence Sepede, senior researcher at Mercer. "So that made European cities go up and U.S. cities drop. " Sepede noted that while U.S. cities got cheaper in relation to those in Europe and Asia, the rankings among: American cities remained similar to previous years, with Los Angeles, Chicago and San Francisco all placing high on the list. Also not able was the climb of Australian and New Zealand cities up the list, a shift caused by those nation's strong currencies. Sydney moved from 67 last year to 20 this year, and Auckland, New Zealand climbed 35 places to 80. The rest of the top 20 remained fairly constant, although Paris, Vienna, Austria and Istanbul, Turkey made their first appearances so high in the rankings.

The survey took into consideration 250 criteria, including the cost of utilities, food and entertainment. While the survey looked at a range of living standards, Sepede said the study was most representative of the expenses of people working for big international corporations and maintaining fairly high standards of living. Mercer said the continued appreciation of the euro against the U. S. dollar could eventually force companies to move employees and reorganize. "Mainly, the depreciation(贬值) of the dollar makes it cheaper to send employees to American cities, " said Jackie Barber, a spokeswoman for the survey.

New York is one of the top ten most expensive cities in the world last year.

A．Right

B．Wrong

C．Not mentioned
