A long, red bridge stretches (伸展) out across the water. It crosses the Golden Gate. This is not the entrance to a sacred (神圣的) land, but it looks just as magical. The Golden Gate is where San Francisco Bay meets the Pacific Ocean. At night, the lights of the bridge create a breathtaking scene. Welcome to San Francisco, a city renowned (闻名的) for its steep hills, beautiful parks and an infamous island prison. With so many famous local landmarks, it’s no wonder that US singer Tony Bennett “left his heart” there. Last year, it ranked as Lonely Planet’s No 1 city to visit.
