Mọi người giúp em giải bài luận này với ạ >.< Fort Collins certainly does its part to uphold Colorado's reputation as one the country's most physically active states. Recreational activities in Fort Collins range from cycling and hiking to snowboarding and kayaking. Thanks to 600 acres of parks, 40,000 acres of natural areas, 20 miles of off-street hike/bike trails, more than 280 miles of on-street bike lanes and a robust lineup of city-run indoor exercise facilities, Fort Collins residents have plenty of opportunities to get their hearts pumping. The city’s vibrant craft brewing scene serves as a hard-earned reward for Fort Collins’ active locals. Fort Collins has long prioritized the performance of its public school system, with efforts that have paid off in spades and made the city one of the country's best places to live. Fort Collins' 41,680 students perform 3 to 19 percent higher than the statewide average in all subjects; and on a national scale, Fort Collins pupils consistently are ahead of the game when it comes to ACT and SAT college entrance exam averages. Fort Collins has invested extensively in its local library system, cultural offerings and public learning opportunities. The city’s Fort Collins Museum of Discovery – a gorgeous hands-on learning space, featuring an array of traditional and pop-science exhibits that fascinate the young and old – is a regional destination. The museum’s marquee attraction, the OtterBox Digital Dome Theatre, screens a variety of nationally and internationally released science and nature films on a 35-foot dome screen. Rounding out the city’s cultural, academic and natural attractions is Fort Collins’ notable slate of industry. Regarded as an engine of economic growth and stability for northern Colorado, Fort Collins enjoys the presence and job provision of Fortune 500 luminaries such as Anheuser-Busch, Eastman Kodak, Hewlett-Packard and Agilent Technologies. Businesses in Fort Collins find strong support from local residents and city leaders.
