Sports can help you keep fit and get in touch with nature．However, whether you are on the mountains，in the waves，or on the grassland，you should be aware that your sport of choice might have great influence on the environment.

　 Some sports are resource-hungry．Golf，as you may know，eats up not only large areas of countryside，but also tons of water．Besides，all sorts of chemicals and huge amounts of energy are used to keep its courses in good condition．This causes major environmental effects．For example，in the dry regions of Portugal and Spain，golf is often held responsible for serious water shortage in some local areas．

　 There are many environment-friendly sports．Power walking is one of them that you could take up today．You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse．Simple and free，power walking can also keep you fit．If you walk regularly，it will be good for your heart and bones．Experts say that 20 minutes of power walking daily can make you feel less anxious，sleep well and have better weight control.

　 Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from reused materials. But the final goal should be" green gyms". They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

The volcano is one of the most surprising frightening things of nature. Maybe you have seen pic­tures of these " fireworks " of nature. Sometimes when a volcano erupts, a very large wall of melted rock moves down the side of a mountain. It looks like a " river of fire". Sometimes volcanoes ex­plode, throwing the melted rock and ashes high into the air. But where does this melted rock come from?

The earth is made up of many layers (层). The top layer that we see is called the crust. Under the crust are many layers of hard rock. But far, far beneath the crust the rock is so hot that it is soft. In some places it even melts. The melted rock is called magma. Sometimes the magma breaks out to the surface through cracks (裂缝) in the crust. These cracks are volcanoes.

Most people think of mountains when they think of volcanoes. But not every mountain is a volca­no. A volcano is simply the opening in the earth from which the magma escapes. The hot magma, or lava as it is called, cools and builds up on the surface of the earth. Over thousands of years, this pile of cooled lava can grow to be very, very big. For example, the highest mountain in Africa, Kilimanja­ro, is a volcano. It rises more than 16,000 feet above the ground around it.

"Time is a problem for children," states a news report for a new Swiss watch.
