单选题{{B}}Passage Three{{/B}} It seems that some people go out of their way to get into trouble. That's more or less what happened the night that Nashville Police Officer Floyd Hyde was on duty. "I was on the way to a personal-injury accident in West Nashville. As I got onto Highway 40, blue lights and sirens going, I fell in behind a gold Pontiac Firebird that suddenly seemed to take off quickly down the highway. The driver somehow panicked at the sight of me. He was going more than a hundred miles an hour and began passing cars on the shoulder." But Hyde couldn't go after him. Taking care of injured people is always more important than worrying about speeders, so the officer had to stay on his way to the accident. But he did try to keep the Firebird in sight as he drove, hoping another nearby unit would be able to step in and stop the speeding car. As it turned out, keeping the Firebird in sight was not that difficult. Every turn the Pontiac made was the very turn the officer needed to get to the accident scene. Hyde followed the Pontiac all the way to his destination. At that point he found another unit had already arrived at the accident scene. His help wasn't needed. Now he was free to try to stop the driver of the Firebird, who by this time had developed something new to panic about. "Just about that time," Hyde says, "I saw fire coming out from under that car, with blue smoke and oil going everywhere. He'd blown his engine. Now he had to stop." "After I arrested him, I asked him why he was running. He told me he didn't have a driver's license." That accident cost the driver of the Firebird plenty—a thousand dollars for the new engine—not to mention the charges for driving without a license, attempting to run away, and dangerous driving.

单选题Many older Americans spend their final years in a nursing home or assisted living center. These places provide services that help older adults with activities they can no longer do on their own. However, most people say they would like to remain in their own homes. Now, there are nonprofit groups that help them do that. Philip Smith is ninety-one years old and lives with his wife in an old house in Seattle, Washington. And he wants to keep it that way. He always says: "As far as I"m concerned, I would not like to leave this place. Living in a group situation is something I couldn"t tolerate. I"d kill myself before I had to do that." Mr. Smith says now he and his wife can take good care of themselves in their two-level house. But he and his wife know they will soon need help with simple housework. Work like changing a light bulb that hangs at the top of the stairs. In the past, an older American would ask one of their children or a neighborhood teenager to change the light bulb. But here, those young helpers have grown up and gone. Mr. and Mrs. Smith have three children, but they all live in other states. So they are considering joining a "virtual village." This is a local group of volunteers and service providers that help older adults. They might help these adults with anything from transportation to small home repairs and dog walking. The virtual village idea was first developed about ten years ago in Boston, Massachusetts. The idea has spread to an unofficial network of villages around the country. One hundred fifty are currently in development.
