     Rock climbing(攀岩) did not become a sport until late in the 1900s. But now it has become a

popular outdoor activity. While rock climbing may still be necessary for mountain climbing, most

people just climb low mountains for fun.

     If you have ever done rock climbing, you will know that it is not a very easy sport. Indoor and

outdoor rock climbing both need practice. What most people don't know is that rock climbing is

one of the sports that depend on your body and mind(意志).

     To climb successfully, one must use wonderful skills(技能). One of the important rules is to

always have three parts of your body on the rock face. Another important rule is that your arms

only hold you close to the rock face while your legs are pushing(推) you up, the closer you are to

the rock face, the easier it is to climb.

     Rock climbing is a wonderful sport. Once you start to learn how to climb, you'll find more fun.

People who like games such as chess playing or problem-solving may love rock climbing, because

they are nearly the same in the way of thinking. For anyone who wants to get into beautiful shape

(体形), rock climbing is a fun and good way. Anyone who enjoys a difficult game and loves the

outdoors should think of taking rock climbing as a new hobby.
