Unit 1 VOCABULARY 1 1 Listen and read. These days, many young people do dangerous and exciting sports called “extreme sports.” They can be done in the air, in the water, or on land. Extreme skiers reach speeds of 240 km (150 miles) an hour and fly the length of two football fields before they land! Another popular land sport is BMX (bicycle motocross). In skiing and BMX, people flip in the air! Kitesurfing is a new kind of surfing. An athlete travels skillfully across the water at speeds of 55 km (35 miles) an hour or more. If he isn’t skillful, he’ll crash. Kitesurfers, called “Charlie Browners,” need lots of strength in their arms. Hang-gliding is one of the most popular extreme sports, although the equipment is expensive. Serious accidents are not common, but sometimes people have injuries when they land. Imagine flying like a bird at a height of 6,000 m (20,000 feet)! 2 Listen and repeat. length Extreme skiers can fl y the length of two football fields. land He landed after hang-gliding for two hours. motocross Motocross can be dangerous. skiing Skiing is my favorite winter sport. flip Some skiers flip in the air. kitesurfing Kitesurfing is fun. skillful She is a very skillful athlete. crash Be careful.
