【题目】Each Sunday, people can hear the music of the Mission Dolores Basilica in San Francisco. The Spanish missionaries（传教士）built the church in 1791. It was the start of a special kind of neighborhood: the Mission District.

The area is a place with a long and varied history. One community member says that it’s important for people to understand the many levels of history in the neighborhood. He feels that_______is a big part of understanding what it means to be a real San Franciscan.

One of the most interesting parts of the district is its people. Over the years, immigrants have come to the area from Ireland, Germany, and Italy. But the most recent immigrants are mainly from Latin America. It’s easy to see the style that these recent additions give to the neighborhood. You can see it in the art on the walls, taste it in the food, and hear it in the music!

Juan Pedro Gaffney, the director of the Spanish Choir（唱诗班）of San Francisco, says that the people there share the pain and the happiness of their friends and family members and that music has always been a basic part of cultural identity in the district. He feels that the music of the district is colorful and lively.

But it isn’t just its music that’s colorful and lively. Its art is full of life as well.

The local art community stays close to the area’s culture and tradition. A local arts organization often leads people on walks through the district. They visit streets like Balmy Alley, which is famous for its murals （壁画）. Even though the meanings behind the murals are always changing, they are still very powerful. One artist explains that they are fighting for fairness in the community and to help the environment through murals. Apparently, they’re something the community likes.

Many of these artists feel that the district is a successful neighborhood where new immigrants are welcome. “People see that they’re not so different from each other,” says one artist. “There are a lot of things that bind（捆绑）the immigrants through culture and tradition.”
