Although the United States covers so much land and the land produces far more food than the present population needs，its people are by now almost entirely an urban society. Less than a tenth of the people are engaged in agriculture and forestry(林业), and most of the rest live in or around towns，small and large．Here the traditional picture is changing: every small town may still be very like other small towns，and the typical small town may represent a widely accepted view of the country，but most Americans do not live in small towns any more. Half the population now lives in some thirty metropolitan areas(1arge cities with their suburbs, of more than a million people each—a larger proportion than in Germany or England，let alone France). The statistics(统计)of urban and rural population should be treated with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day. As the rush to live out of town continues，rural areas within reach of towns are gradually filled with houses, so that it is hard to say at what moment a piece of country becomes a suburb. But more and more the typical American lives in a metropolitan rather than a small town environment．

Why don’t birds get lost on their long migratory (迁居的) flights? Scientists have puzzled over this question for many years. Now they’re beginning to fill in the blanks.
Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly by night? Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the stars in their long-distance flights.
One such bird, a warbler(鸣禽) , had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird’s cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the direction of the make-be-live stars caused a change in the direction of his flight. Scientists think that warblers, when flying in daylight, use the sun for guidance. But the stars are apparently their main means of navigation (导航). What do they do when the stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it’s too dark to see these, the warblers circle helplessly, unable to get their direction.

By my third day in the hospital, I realized Tom didn’t visit. I couldn’t understand 36 my best friend wouldn’t come to see me. Struggling against the 37 , I phoned his __38 . His mother answered, and when I asked for Tom, she got 39 . “He’s not here right now,” she said. I thought it was 40 that she didn’t tell me where he was or 41 to have him call me. But I was so weak, I just let it 42 . I found out later that Tom’s mother called my parents right after we rang 43 . My phone call really made her 44 , and she 45 they talk to me. Later that night, my mom 46 . Did I remember drinking? Did I remember in a car？I had 47 what she was talking about, so she finally told me the news: I’d hit a tree. Tom, in the 48 seat, was thrown from the car and killed instantly. The only reason I’d lived was because of my 49 .
My first 50 was of shock. I’d been drink-driving? Hit a tree? Killed Tom? I felt like the 51 person in the world. Even after I was able to 52 several weeks later, I didn’t want to eat, I didn’t want to talk. I just 53 at the wall in my 54 and cried. The only person I wanted to see was Tom. I didn’t feel like 55 with any of my old friends.
