Many years ago, most of our earth wascovered with blocks (块) of ice. These iceblocks were as tall as high buildings in modern cities. Most of the ice was inthe northern part of the world. Then the ice blocks started to move south. Coldand rain came with the ice. Animals had to move. At last, the ice began to melt(融化). After half a million years, most of it melted.More than half of the earth became covered with water. Theclimatebecame much warmer. Things began to grow. The earth began to look the way inwhich it looks today.

Many sports stars believe something can bring them good luck. Some of them like to wear their lucky clothes, some like special numbers and some do special things for good luck on the day of an important game. Next I'll give you some examples.

Serena Williams, a tennis player, ties her shoelaces(鞋带) in the same way before every game. She usually wears the same socks in all games. She also has lucky shoes and likes having a dress with her. Another tennis star, Rafael Nadal, puts two water bottles in the same place next to the tennis field before every game. When he wins a competition, he always bites the trophy(咬奖杯).

The Spanish football player, Fernando Torres, always has three shirts, three pairs of shorts and three pairs of shoes in his sports bag. Kolo Touré is always the last player going onto the football field before games. He believes that numbers like 11,22 or 33 on a player's shirt can bring the player good luck. He also thinks it is unlucky to change the numbers when he goes to another team.

One racing driver. Sebastian Vettel, doesn't have a special thing to do but he has lucky things. He has a necklace (项链) and a little toy pigl They are surely special to him.
