It is unique in that it is a sport where able and disabled persons, and people as young as 5 years and as old as 80 years of age can participate alongside each other. It is a sport that involves more than one person, and is a wonderful family activity that gathers members together for a day of fun at a favorite waterway. Anyone who has put on water skis can attest to its health benefits--it is a sport that demands and develops strength, agility and endurance. The sport includes several disciplines including slalom, tricks, cable, jump, ski racing, kneeboard, wakeboard, and barefoot, with each of these practiced for either recreational or competitive enjoyment. Safety Tips for Water-Skiers Don't take unnecessary risks while water-skiing. The following tips will help you safely enjoy this thrilling sport: ALWAYS have an observer in the boat. This is a legal requirement in many states. The boat driver cannot watch the skier and operate the boat safely at the same time. ALWAYS wear a Coast Guard approved Personal Flotation Device (PFD) designed for water skiing. Ski belts are NOT recommended. Your approved PFD will help keep you afloat. NEVER ski in rough water. High waves or a choppy sea will prevent the tow boat from maintaining a steady course and speed. NEVER ski after dark. It is dangerous AND illegal. Any boat traveling fast enough to tow a skier is traveling too fast to navigate safely at night. NEVER water-ski while under the influence of alcohol or drugs. Such activity is extremely dangerous because of the impairment to your judgment and ability to respond. A recent study conducted with expert skiers who were purposely drunk indicated that even their ability to ski was dramatically reduced. Use hand signals between the skier and observer. Agree before you start what each signal means so there is no confusion at a critical moment. Question: Which of the following is against law while water skiing? Options: A: An observer doesn't watch the skier. B: A skier doesn't fasten his safe belt. C: Go skiing at midnight. D: Go skiing after drinking wine.

Tim knew it would soon be swallowed by the waves. "Everything went quiet in my head,"Tim recalls ."I was trying to figure out how to swim to the boys in a straight line."

Christian made much effort to take down the umbrella.Then Tim was able to catch up and climb aboard the boat.He took over rowing,but the waves were almost too strong for him. "Let's aim for the pier ,"Jack said.Tim turned the boat toward it.Soon afterward,waves crashed over the boat,and it began to sink."Can you guys swim?"he cried."A little bit,"the boys said. Once they were in the water,Tim decided it would be safer and faster for him to pull the boys toward the pier.Christian and Jack were wearing life jackets and floated on their backs.Tim swam toward land as water washed over the boys'faces. "Are we almost there?"they asked again and again."Yes,"Tim told them each time. After 30 minutes,they reached the pier. Question: Why did Tim raise his head regularly?
