Often, it’s accompanied by an appeal: “Just think about those starving orphans in Africa!” Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of staying “clean the plate”, perhaps we should save some food for tomorrow. According to news reports, US restaurants are partly to blame for the growing bellies. A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little. Barbara Rolls, a nutrition professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline began to expand. Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this, too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believe restaurants serve ‘portions that are too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can’t afford fine dining still prefer large portions. 70 percent of those earning at least $150,000 per year prefer smaller portions; but only 45 percent of those earning less than $ 25,000 want smaller. It’s not that working class Americans don’t want to eat healthy. It’s just that, after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck to paycheck, happy to save a little money for next year’s Christmas presents. Parents in the United States tend to ask their children

Some scholars have associated trade unions with the medieval craft guilds(中世纪的行会), but there are important differences between the two. The guild members were master craftsmen who owned capital and often employed workers. Unions are known as associations of workers with similar skills. 2. In the past, individual workers had no control over the conditions of their working lives; political and economic power was concentrated in the hands of wealthy business owners. Workers found, however, that there was strength in uniting. From their earliest years, union objectives have been higher wages and improved working conditions. 3. Employers resisted, of course. They made great efforts to stop union organizing its activities. Union members were fired, workers were forced to sign contracts in which they promised not to join a union, and companies hired strikebreakers (破坏罢工者) and even gunmen to frighten organizers. 4. One of the earliest successful labor organizations in the United States was the Knights of Labor, founded in 1869. The Knights, which included both skilled and unskilled workers, attempted to organize all workers into one great union. Alter it successfully struck the Wabash railroad owned by Jay Gould in 1885, its popularity and power grew dramatically. In 1886 the Knights had 700,000 members. 5. The decline of the Knights of Labor, however, came quickly. The strike against Gould was gradually broken, and the Knights’ radical positions on social issues cost them public support. In the end, a lack of unity as well as the rapid inflow of unskilled immigrants weakened the union’s economic power, and the organization came to an end. Knights lost its popularity because it took______.
