A long red bridge stretches out across water. It runs across the Golden Gate. This is not the entrance to some sacred (神圣的)land,but it is just as magical. The Golden Gate is where San Francisco Bay meets the Pacific Ocean, and at night the scene of the bridge lit up over the water takes your breath away.

Welcome to San Francisco, a place famous for its beautiful parks, hilly streets and lovely beaches. But the bridge is undoubtedly the most well-known symbol of the city. Before its completion in 1937, the bridge was considered impossible to build because of the foggy weather ,powerful winds, and strong ocean currents (洋流)in the city. However, despite the difficult conditions, the bridge was built in no more than four years. Its total length is nearly 2 kilometers.

San Francisco ranks first on Lonely Planet’S list of best cities to visit in 2013. According to the world’s largest travel publisher, it came top as a result of its cultural mix.

According to the US 2010 census (人口普查),21 percent of the city’s population is made up of Chinese people. San Francisco’s Chinatown is the largest outside of Asia and the oldest in North America. Two traditional festivals, the Spring Festival and Mid-Autumn Festival, are the biggest events of the year on the city’s calendar.

If yellow cabs (出租车)are a key part of New York city life, then the cable car (缆车) is San Francisco’s equivalent. The first cable car came into public service in 1873, and the slow and noisy vehicle has been a symbol of the city ever since. The cable car network was once damaged by a serious earthquake but, luckily, it has now recovered and provides better views than the subway.
