1 . People believe that climbing can do good to health. Where can you learn the skill of climbing then? If you think that you have to go to the mountains to learn how to climb, you’re wrong. Many Americans are learning to climb in city gyms. Here, people are learning on special climbing walls. The climbing wall goes straight up and has small holding places for hands and feet.

How do people climb the wall? To climb need special shoes and a harness around your chest to hold you. There are ropes tied to your harness. The ropes hold you in place so that you don’t fall. A beginner’s wall is usually about 15 feet high, and you climb straight up. There are small pieces of metal that stick out for you to stand on and hold on to. Sometimes it’s easy to see the new piece of metal. Sometimes, it’s not. The most difficult is to control your fear. It’s normal for humans to be afraid of falling, so it’s difficult not to feel fear. But when you move away from the wall, the harness and the ropes hold you, and you begin to feel safe. You move slowly until you reach the top.

Climbing attracts people because it’s good exercise for almost everyone. You use your whole body, especially your arms and legs. This sport gives your body a complete workout. When you climb, both your mind and your body can become stronger.

2 . Whether you are racing or touring, long-distance cycling can be very rewarding.     1     In general, it is more important to prepare your mind and your gear (齿轮) for the challenge ahead than it is to train your body. The best way to physically train for a long cycling trip is to take a long cycling trip! There are several steps for you.

Stretch first! Warm up for at least ten minutes before each long-distance cycling session.     2     This way, you can reduce the risk of injury.

Pace yourself.     3     Try to keep up this pace as best you can. Use a lower gear so that you don't wear yourself out. Try to keep up a rate of roughly 90 rpm(revolutions［旋转］per minute) on a low gear to go easy on your muscles and lungs.

Shift gears. When you come to a hill, change into a lower gear so that you can more easily reach the top.     4     Throughout the ride, stay aware of how hard you are working. If you are struggling to push the pedals (踏板), you should switch into a lower gear to conserve your energy.

    5     Even if you feel strong, stop every 10-20 miles to give your body a rest and ensure that everything is running smoothly. Rehydrate (补水) by drinking some water, and boost your energy levels with a quick snack. Keep doing so until you arrive at your destination.
