Around the world in 30 seconds—it is not a wild idea of space age but the time it takes to finish that journey at the South Pole （南极）. Visitors to the South Pole like to walk around the world. So there is a well-known path in the snow there. Other visitors like to stand on their heads or have their pictures taken with the flags of the Antarctic （南极的） countries in the background. They think it is interesting and exciting. The United States has a base at the South Pole. The Chinese scientists and technical workers have built an observation station there， too.

If you go from the very pole towards America， you are in one time zone. If you head towards Australia or towards South Africa， you are in other zone. It is Friday if you stand on one side of the pole. And if you walked around the other side， it is Thursday over there.

The air at the South Pole is the cleanest on earth. Scientists from various countries have called for Antarctica to be declared （宣布） as a world park to save it from being polluted by the exploitation of its oil and other mineral resources.
