Many forms of cancer can be cured if detected early.His shoes were shined to perfection.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.

Consumers have benefited greatly from those advances. People who predicted that the world would run out of food were wrong. We are producing more and more food with less and less capital. Food is therefore more plentiful and cheaper than it has ever been. Spending on food compared with other goods has fallen for many years,and continues to drop. 2 Supermarkets have helped push down prices mainly because of their scale. Like any big business,they can invest in IT systems that make them efficient. And their size allows them to buy in bulk. As supermarkets get bigger,the prices get lower. 3 Huge retail companies such as Wal-Mart have tremendous power and they can put pressure on producers to cut their margins. As a result,some producers have had to make cuts. In recent years,Unilever has cut its workforce by 33,000 to 245,000 and dropped lots of its minor brands as part of its “path to growth” strategy. Cadbury has shut nearly 20 per cent of its 133 factories and cut 10 per cent of its 55,000 global workforce These cuts help keep costs down,and the price of food stays low. 4 Does cheap food make people unhealthy? Cheap food may encourage people to eat more. Food companies certainly think that giving people more food for their money makes them buy more. Giving people bigger portions is an easy way of making them feel they have got a better deal. That is why portions have got larger and larger. In America,soft drinks came in 8oz (225g) cans in the past,then 12oz (350g),and now come in 20oz (550g) cans. If a company can sell you an 8oz portion for $7,they can sell you a 12oz portion for $8. The only extra cost to the company is the food, which probably costs 25 cents. 5 Now companies are under pressure to stop selling bigger portions for less money. But it is hard to change the trend.
