Watercress is positively packed with healthy vitamins and minerals. The writings of both the Romans and the Ancient Greeks record the consumption of watercress by all classes. Hippocrates, "the father of medicine", was so convinced that watercress was a great healer that he built his first hospital next to a stream so that he could grow a plentiful supply of the shiny green leaves for his patients. The Romans chewed watercress in large quantities, believing that it would cure baldness. They, too, looked with favor on watercress as a salad. Watercress sandwiches were traditionally a breakfast item in nineteenth-century Europe. The most basic type of watercress sandwich has two pieces of white bread with a mixture of butter and watercress greens . A nickname for the vegetable, in fact, was "poor man's bread", because watercress was often eaten on its own for breakfast by families that could not afford the bread to go with _ . Watercress is a member of the mustard family. It contains vitamins C(66mg per 100g), K and A, and is also a valuable source of minerals such as iron, potassium, copper and calcium. The mustard oils in its silky leaves and stems contain an ingredient known as PEITC. Recent research has proved that PEITC can prevent the growth of cancer cells and, in some cases, actually destroy them. The best watercress has silky green leaves without any marks and has undamaged stems, The older the plant, the darker are its leaves and the thicker its stems. This means a higher concentration of oils and vitamins. Young watercress, on the other hand, may be harvested after only twenty-eight days growth and has a milder taste. It is best to eat watercress fresh and raw , to keep more of its valuable nutrients, but it can be lightly cooked and used as an alternative to spinach--another dark green vegetable--in various recipes. From soups to salads, watercress is now considered around the world as a natural and healthy super food. Compared with older watercress, young watercress _ A) has lighter green leaves B) contains more minerals C) is better for medical use D) is more suitable for eating raw

It will be hot--hot enough that most locals will have cleared town for cooler places. But because athletes competing at the 2004 Olympics have no choice but to stay in the hot weather, many plan to turn to science to stay cool. Some will put their hands in ice water just before competing and nearly all will be wearing fabrics designed with hot weather in mind. "Normally we warm up before exercise,"said Gordon Sleivert, director of sports science and medicine at the Canadian Sport Center in Victoria, British Columbia."But in this case we're taking the warm out of warm up. It's like pre-cooling." Experts are predicting the average high this August in Athens will be 90 degrees Fahrenheit, with temperatures often reaching above 100(the average temperature in Sydney for the 2000 summer games was 64). Although some events, such as the marathon, will start early(1 a.m.) to avoid hot weather, _ Drinking lots of water will help athletes keep cool, but humidity remains a problem. The body's ability to cool down is weakened by damp air since sweat drips off the skin rather than evaporates ,resulting in dehydration without the cooling. "Getting hot is a real problem because when our brains heats up, the brain waves are more like when you're really sleepy. Everything feels harder," said Sleivert. The following things will be likely to happen in the hot weather EXCEPT _ . A) dehydration B) being sleepy C) that the blood in the body can become less and less D) that the body's ability to cool down is weakened
