Passage D (Questions 38-41) During the early years of American settlement, a highly distinctive form of English was beginning to develop in the islands of the West Indies and the southern part of the mainland, spoken by the incoming black population. The beginning of the seventeenth century saw the emergence of the slave trade. Ships from Europe travelled to the West African coast, where they exchanged cheap goods for black slaves. The slaves were shipped in barbarous conditions to the Caribbean islands and the American coast, where they were in turn exchanged for such commodities as sugar, rum, and molasses. The ships then returned to England, completing an 'Atlantic triangle' of journeys, and the process began again. Britain and the United States had outlawed the slave trade by 1865, but by that time, nearly 200 years of trading had taken place. By the middle of the nineteenth century, there were over four million black slaves in America. Source: http://www.miguelmllop.com/practice/intermediate/readingcomprehension/blackenglish.htm

Size, weight, shape and color all have an effect on flavor, says a University of Oxford team. Cheese tastes saltier when eaten from a knife rather than a fork; while white spoons make yoghurt taste better, experiments show. The study in the journal Flavor suggests the brain makes judgments on food even before it goes in the mouth. More than 100 students took part in three experiments looking at the influence of weight, color and shape of cutlery on taste. The researchers found that when the weight of the cutlery confirms to expectations, this had an impact on how the food tastes. For example, food tasted sweeter on the small spoons that are traditionally used to serve desserts. Color contrast was also an important factor - white yoghurt eaten from a white spoon was rated sweeter than white yoghurt tasted on a black spoon. Similarly, when testers were offered cheese on a knife, spoon, fork or toothpick, they found that the cheese from a knife tasted saltiest. "How we experience food is a multisensory experience involving taste, feel of the food in our mouths, aroma, and the feasting of our eyes," said Prof Charles Spence and Dr Vanessa Harrar. "Even before we put food into our mouths our brains have made a judgment about it, which affects our overall experience." Past research has shown that crockery can alter our perception of food and drink. For example, people generally eat less when food is served on smaller plates. The new research into how the brain influences food perceptions could help dieters or improve gastronomic experiences at restaurants, said Prof Spence. He told BBC News: "There's a lot more to food than what's on the plate. Many things we thought didn't matter do. We're going to see a lot more of neuroscience design around mealtimes."
