Passage 41
学霸导读 对于喜爱攀岩却又没有足够时间和金钱的运动爱好者来说，室内攀岩是一个不错的选择。
I’ve always wanted to try rock climbing, but never had the time or money for it. But I’ve discovered a way to e 1 the excitement of climbing rock. Indoor climbing is an easy and exciting way to get a taste of rock climbing. And it is also much cheaper and safer! Indoor climbers don’t climb on r 2 rock, but on a plastic wall. You can probably f ind a climbing wall near you. Many gyms, schools and camps have one.
You can climb indoors at any time of the year， no matter how the weather is. It is usually not expensive. Most gyms p 3 the equipment you need. The convenience of indoor climbing is one reason why it has become so popular. But the r 4 people climb is for rush （ 刺激感 ） they get. When I stand at the foot of the wall and look up， I’m always scared， but once I start climbing， fear changes to determination. With my heart pounding （ 剧烈跳动 ）， I reach the top and look down. I can’t stop grinning. I did it！
Indoor climbing is a great workout （ 锻炼 ）. Climbing uses muscles （ 肌肉 ） that are hard to exercise， e 5 those in the shoulders， arms， chest and back. Many people say climbing makes exercise fun. Most gyms have several climbing walls with v 6 degrees of diff iculties. The easy ones are like climbing a ladder. The diff icult ones bulge out （ 凸出 ） in places so that climbers sometimes must climb parallel with the f loor.
Although gym climbing is safer and simpler than real rock climbing， you should still be careful. Always climb with a partner. As you climb， your partner pulls your climbing rope t 7 something called a belay device （ 绳索控制器 ）. The belay catches you if you slip. But make sure your partner knows how to use this equipment. And if you are a f irst-time climber， get some instruction before you begin.
