Article: It was the last time Susan Butcher ran the Iditarod Trail Sled Dog Race in 1992. An hour into the race, Susan and her sled dog team sped down a hill and crashed into a fallen tree. Although hurt, Susan continued the difficult race. The Iditarod Race started in 1925 when a doctor in Nome, Alaska was desperately in need of medicine to stop the spread of a deadly disease. Only a hospital had what he needed, but it was 700 mile-away! In January, it was too dangerous to send a boat and too stormy for his tiny airplane. The only hope was to use several sled dog teams following a trail, called the Iditarod Trail. They passed the medicine from one sled team to another. Wind and snow did not stop the men and their dogs. The medicine was delivered in record time. The race follows the route of the famous medicine run. Over 1,000 miles long, it is considered the toughest race in the world. Susan Butcher was born in Cambridge, Massachusetts. In her teens Susan was given a Siberian husky dog and became very interested in huskies as sled dogs. After reading about the Iditarod Race, Susan moved to Alaska. She got several jobs to earn money to buy herself a sled and a team of huskies. After years of hard work and training, Susan achieved her dream of racing on the Iditarod Trail. In 1978, at the age of 24, Susan entered the race for the first time and became the first woman to finish in the top 20. In 1982 she came in second. In 1984 she was leading her team across a frozen waterway when they fell into the water. Her lead dog managed to pull Susan and the other dogs out of danger. Remarkably, she came in second. In her fourth race, in 1985,a starving moose attacked her dogs, killing two and injuring eleven. Susan had to leave the race. In 1986 Susan joined the race again. This time, she won. She won again in 1987. In 1988 she became the first person ever to win three Iditarod races in a row. Unbelievably, Susan won for the fourth time in 1990.

Article: Expressions about water are almost as common as water itself. The expressionto be in hot water is a very old expression. Hot water was used five hundred years ago to mean being in trouble. One story says it got that meaning from the custom of throwing extremely hot water down on enemies attacking a castle. That no longer happens. But we still get in hot water. When we are in hot water, we are in trouble. It can be any kind of trouble--serious or not so serious. A person who breaks a law can be in hot water with the police. A young boy can be in hot water with his mother, if he walks in the house with dirty shoes. Beingin deep wateris almost the same as being in hot water. When you are in deep water, you are in a difficult position. To keep your head above wateris a colorful expression that means staying out of debt. A company seeks to keep its head above water during economic hard times. A man who loses his job tries to keep his head above water until he finds a new job. Water over the dam is another expression about a past event. It is something that is finished. It cannot be changed. The expression comes from the idea that water that has flowed over a dam cannot be brought back again. Another common expression to hold water, is about the strength or weakness of an idea or opinion that you may be arguing about. It probably comes from a way of testing the condition of a container.; If it can hold water, it is strong and has no holes in it. If your argument can hold water, it is strong and does not have any holes. Throwing cold water also is an expression that deals with ideas or suggestions. It means to not like an idea. For example, you want to buy a new car because the old one has some problems. But your wife throws cold water on the idea, because she says a new car costs too much.

Article: Is there a nationwide shortage of nurses? It's hard to say. However, some characteristic symptoms often indicate that there is indeed a shortage. One symptom is the vacancy rate, or the percentage of budgeted positions that are unfilled. New England's hospitals currently report that an average of 7 to 12 percent of their registered nurse positions are vacant, the highest level since the last shortage in the late 1980s. Vermont has a ly low vacancy rate, at 7.8 percent. But its vacancies were at 1.2 percent just five years ago. Another symptom is the increased use of stopgap measures to fill empty positions. For instance, many nurses report an _ in how frequently they are asked to stay past their shifts. According to Murphy, working in the St. Elizabeth's Hospital, "The shortage has definitely created a lot of opportunities of overtime for our nurses, whether they want them or not." Similarly, a national survey of registered nurses shows that in an average week, nurses in the U.S. work 2.4 more hours than they are scheduled to. Much of this extra time is voluntary, as nurses earn overtime pay when they stay to fill in blanks in the schedule. When they can't fill open positions by more traditional means, health care providers hire temporary staff to tide them over. Travelling workers are the largest part of the temporary health care workforce, hired for thirteen-week reduction at health care facilities facing short-term lack of workers. Temporary workers, mainly nurses, cost hospitals $ 7.2 billion in 2000. "Any successful solution to the shortage depends on convincing more people to become nurses, and that is not an easy goal to reach. To achieve it," says Buerhaus, "society needs to place more value on nursing. Legislation can't do that - it should come from people." And if this continues, we might have to learn to care for ourselves in the hospital.
