Read the following article and select the best answer. Article: Winter is a great time to experiment with new sports. The key is to find one that matches your interests and natural abilities. If you like to walk, keep walking -- on snowshoes. If you want to try an endurance sport, go for cross-country skiing. Besides, snowboarding is just great fun. Not satisfied with these? Try downhill skiing, then. Downhill skiing is not as hard as it used to be -- shorter, lightweight, curved skis make any beginner feel like an Olympic winner. These newer skis -- along with another type of equipment called skiboards, which are even shorter than skis -- help you control your speed and body movements. Consider testing the latest high-tech skis or snowboards?Check with your local sports shops or the rental places at the ski mountains about sample programs. You could also try sledding. Use a wood-framed sled with steel runners or a plastic sled to head down a snowy hill. If you prefer ice to snow, think hockey or figure skating. Runners can also train during the winter in spite of wet or slippery roads. One of the easiest sports around, snowshoeing can be excellent cold-weather cross-training for runners and cyclists -- or anyone wanting to take a wintry walk in the woods. Snowshoes are smaller, lighter, and better than ever. If you want to try them out, you may be able to rent a pair for a day at many of the larger outdoor or sporting goods stores. Whatever sport you choose, don't rely on a friend for instruction. You wouldn't let an inexperienced doctor perform a brain operation on you, but why let one teach you to ski or skate? That's what instructors are for -- to help newcomers start out right. Instructors can give you advice about equipment, techniques, safety, and dealing with injuries if they do happen to you. Above all, if you want to progress, invest your time in learning the basic skills thoroughly. Everything else you do as a skier, boarder, or skater will be built on these first skills. Question: What can we learn from the passage? - Runners and cyclists cannot train because of the wet or slippery roads in winter. - Downhill skiing used to be more difficult to learn because of the old-fashioned skis. - People can rent snowshoes for a day at their local sports shops or the rental places. - In general, first skills are more important in skiing than in snowboarding or skating.
Downhill skiing used to be more difficult to learn because of the old-fashioned skis.

Read the following article and select the best answer. Article: With hospitals and nursing homes tending to thousands of patients every year accidents can---and do ---happen. These incidents whether they are through carelessness or otherwise, can leave patients feeling powerless. That's not the case. "There is growing public awareness. People are feeling they have more rights and they have tools in hand to make a complaint," said Ralph Montano, spokesman for the California Department of Public Health, which regulates hospitals and long term care facilities in the state. That department received more than 6000 complaints about hospitals in 2007; in the most recent year statistics are available. The complaints can be about mixed-up lab results, medicine errors, foreign objects left in a patient during surgery or a host of other topic. Similarly, the California Department of Aging received 43000 nursing home complaints in 2009. Some said patient abuse or neglect of patients; others reported missing items. And some commented on the quality of the food. But finding the channels through them to put forward a complaint can be tiring and time consumption. Many consumers simply don't bother, and some become lost in the system. Whether the complaint is against a hospital or a long-term care facility, the process is similar--- and many people can help, including the facility's staff, insurance company representatives and state regulators. If you want to make a complaint while in the hospital, Patti Harvey, vice president of quality and patient care services for Kaiser Permanente in Southern California, recommends talking with the bedside nurse. If that doesn't work, you can talk with other people higher in the chain of command, up to the hospital administrator. If the problem isn't still taken care of ---say you disagree with your treatment plan or have a problem with your doctor---member service offices at each hospital can help address your concerns. Question: Many consumers don't make a complaint because _ . - few accidents happen - it takes time to make a complaint - many complaints are lost - complaints are bad for a long-term care facility
it takes time to make a complaint

Read the following article and select the best answer. Article: Many people say dolphins are very intelligent. They seem to be able think, understand, and learn things quickly. But they are smart like humans or more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish. Question: Which of the following best describes dolphins? - Talkative and easygoing. - Carful and hardworking. - Brave and determined. - Friendly and smart.
Friendly and smart.
