Puerto Rican Cuisine (菜肴） Puerto Rico, a Caribbean (加勒比海地区)island rich in history and remarkable natural beauty, has a cuisine all its own. Immigration (移民)to the island has helped to shape its cuisine, with people from all over the world making various contributions to it However, before the arrival of these immigrants, the Taino people lived on the island of Puerto Rico. Taino cuisine included such foods as rodents (啮齿动物),fresh shellfish and fish fried in corn oil. Many aspects of Taino cuisine continue today in Puerto Rican cooking, but it has been heavily influenced by the Spanish, who invaded Puerto Rico in 1508，and Africans, who were initially brought to Puerto Rico to work as slaves. Taino cooking styles were mixed with ideas brought by the Spanish and Africans to create new dishes. The Spanish extended food choices by bringing cattle, pigs, goats, and sheep to the island. Africans also added to the island’s food culture by introducing powerful, contrasting tastes in dishes. In fact, much of the food Puerto Rico is now famous for—coffee , coconuts, and oranges — was actually imported by foreigners to the island. A common assumption many people make about Puerto Rican food is that it is very spicy (辛辣的).It’s true that chili peppers are popular;aij caballero in particular is a very hot chili pepper that Puerto Ricans enjoy. However, milder (微辣的)tastes are popular too, such as sofrito. As the base of many Puerto Rican dishes, sofrito is a sauce made from chopped onions, green bell peppers, sweet chili peppers, and a handful of other spices. It is fried in oil and then added to other dishes. Who lived in Puerto Rico first?

However, middle class is not a real designation, nor does it carry privileges (特权).It is more of a perception, which probably was as true as it ever could be right after World War II. The economy was growing, more and more people owned their own homes, workers had solid contracts with the companies that employed them, and nearly everyone who wanted a higher education could have one. Successful people enjoyed upward social mobility. They may have started out poor, but they could become rich. Successful people also found that they had greater geographic mobility. In other words, they found themselves moving to and living in a variety of places. The middle class collectively holds several values and principles. One strong value is the need to earn enough money to feel that one can determine one’s own economic fate. In addition, middle-class morality (道德观)embraces principles of individual responsibility, importance of family, obligations to others, and believing in something outside oneself. But in the 1990s those in the middle class found that there was a price for success. A U.S. News World Report survey in 1994 indicated that 75 percent of Americans believed that middle-class families could no longer make ends meet. Both spouses (配偶)now worked, as did some of the children , long commutes (通勤)became routine, the need for child care put strains on the family, and public schools were not as good as they once were. Members of the middle class were no longer financing their lifestyles through earnings but were using credit to stay afloat (透支).The understanding of just what middle class meant was changing. In the years after World War Il，the middle class were {pz_填空}.
