Vancouver (温哥华) is a cosmopolitan (世界性的) city of stunning beauty.Set between the waters of the Strait of Georgia and the Coast Mountains, Vancouver is a place of tremendous physical beauty. Few other places in North America offer the attractions of a truly cosmopolitan city so close to such a wide range of natural wonders.You can take advantage of the city’s pleasing mid-70s summer weather with a walk or bike ride through the city’s 1,000 - acre Stanley Park, located on a peninsula just off the downtown business district. A mere 15-minute drive from downtown gets you to Grouse Mountain, which you can climb by foot or aerial tram for a spectacular one-mile-high view of the city and its surroundings. Another worthwhile day trip is the 1.5 hours ferry ride to the seaside town of Victoria, on Vancouver Island, with its lush gardens and 19th century architecture. July and August are the best months to catch a close up view of orcas migrating north through the gulf waters off Vancouver. And two hours from the city is the Whistler-Backcomb ski resort, North America’s largest, which has great off-season prices, a full range of outdoor activities and even summer glacier skiing.Vancouver is home to North America’s third largest Chinatown. The city’s rich Asian culture also lets you take in sights that you can’t find elsewhere on this continent, like the not-to-be-missed Dr. Sun Yat-sen Classical Chinese Garden, which is the only Ming Dynasty style garden outside China. The underlined phrase "has great off-season prices" probably means().

A. has a little low prices
B. has very low prices
C. has a little high prices
D. has very high prices
