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. 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 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, 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.

Everybody says that youth is the best time for our lives. Being young means romance, love and new discoveries, but it is also the most difficult time, because you have to make some very important decisions, which will influence your future life.
Things are not easy nowadays even for adults, but for teenagers, Who have to find their own place in society, it’s even difficult. It is necessary not only to adapt to society, but also to be confident of your position in five, ten or even twenty year’s time.
For the future it is important to have a good nob. In order to get a really good job, you have to be well educated.
Emotional problems for young people can be very important, too. The first teenager problem is that “nobody understands me”. Some parents often continue to treat their children as little children when they are starting to consider themselves to be adults.
There are also some global problems. Young people in all countries are facing these problems. Let’s start with smoking. According to studies, at the age of 16, almost 72% of all boys and 37% of all girls in Russia have already tried smoking. Smoking is not a natural need.It’s just that teens try it when they want to appear to be more like adults.
Drugs are also a serious problem. Students know the names of drugs well enough. 32% say they have tried drugs at least once, mainly because they were having fun, their friends influenced them to, they wanted to relax or they wanted to seem “cool”. That’s too bad.
So, you see, problems do happen and they can’t be ignored. We should pay much attention to them.
