题目内容
Although cliff diving may bring great excitement, it’s a very dangerous sport that people should be careful about. It is completely wrong to think that the diver is cushioned by the water below—this could not be further from the truth. When jumping from a cliff that is over 70 feet high, a diver hits the water at over 46 mph (miles per hour). Such high speeds make the point of contact feel like a wall, so the diving skills are very important.
Professional divers are trained and well-prepared to make dives. However, non-professionals should never dive because a diver’s body position at the time of contacting water is very important to his or her safety. Because of the great danger, divers should always seriously think about their skills before trying any moves.
Although there is no truly safe way to jump off a cliff, non-professional divers are encouraged to pencil dive. To do a pencil dive, the jumpers leap their feet first off the cliff, keep arms at their sides with legs together and pointing downward. The diver should keep the body tight and vertical. This is safer because it makes the point of contact smaller when the diver enters the water and puts less stress on the body.
Wearing a wet suit while diving will result in less pain. So it is wise for new divers to wear wet suits. But professional divers suggest staying away from water shoes. Although wearing shoes might seem like a good idea, they actually increase the force of impact because they increase the surface area of the diver at impact. The increased force of impact puts stress on a diver’s body and can lead to broken bones. Without a doubt, diving without shoes is the safer way to go.
Besides the height, speed, water depth and body position, it is also important for divers to make wise decisions when they are thinking about diving. Cliff diving tests both a person’s physical and mental skills, so it is never a good idea to jump with a sudden idea. A person needs to be of sound mind and in good health to even think about a dive. One should never try a dive if he has drunk wine. What’s more, a person should never make someone who is not feeling 100% confident dive.
