1. Read the text, give it a name and make questions to which the sentences after the text can be answers. Use a dictionary if necessary.
Man has been skating in one way or another for more than 500 years. Ice skating is much older than roller skating, since roller skating goes back only to the eighteenth century.
Wheeled skates were used on the roads of Holland about 200 years ago, and we cannot really know who was the first to make them or use them. A man in New York called J. L. Plimpton invented the four-wheeled skate in 1863, after which this sport became really popular. Roller skate races were popular in most United States cities until about 1910, when motor¬cycle and automobile races took their place. But, of course, roller skating has remained a favourite sport with young people.
Ice skating goes back beyond the 16th century. At that time the Vikings bound runners made of bone to their feet and skimmed on the ice. Iron runners were next used in skating, followed by the steel runners of today. In early days, the skate-runner was attached to the foot by leather thongs. Later, the skate was strapped to the shoe. In the modern skate the blade is permanently attached to the skating shoe.
1. ...? — It is more than 500 years old.
2. ...? — Roller skating appeared in the 18th century.
3. ...? — J. L. Plimpton did.
4. ...? — Because motorcycle and automobile races took place of roller skating.
