Unit2 精彩冬奥—冰上世界 Sports1—Skating 08

ZM: Where do the athletes do speed skating?

K: Olympic speed skating is on an oval track. Skating first began as a rapid form of transportation across frozen lakes, rivers, and canals. As it became a popular sport, clubs were formed and artificial rinks were built, so people could skate all through the year,not just in the winter season.
