时刻准备着暑假作业原子能出版社系列答案One thing the tour books don’t tell you about London is that 2,000 of its residents are foxes. They ran away from the city about centuries ago after developers and pollution moved in. But now that the environment is cleaner, the foxes have come home, one of the many wild animals that have moved into urban areas around the world.
“The number and variety of wild animals in urban areas is increasing,” says Gomer Jones, president of the National Institute for Urban Wildlife, in Columbia, Maryland. A survey of the wildlife in New York’s Central Park last year tallied the species of mammals, including muskrats, shrews and flying squirrels. A similar survey conducted in the 1890s counted only five species. One of the country’s largest populations of raccoons (浣熊) now lives in Washington D.C., and moose (驼鹿) are regularly seen wandering into Maine towns. Peregrine falcons(游隼) dive from the window ledges of buildings in the largest U.S. cities to prey on (捕食) pigeons.
Several changes have brought wild animals to the cities. Foremost(首要的) is that air and water quality in many cities has improved as a result of the 1970s pollution-control efforts. Meanwhile, rural areas have been built up, leaving many animals on the edges of suburbs. In addition, urban wildlife refuges (避难处)have been created. The Greater London Council last year spent￡750,000 to buy land and build 10 permanent wildlife refuges in the city. Over 1,000 volunteers have donated money and cleared rubble from deserted lots. One evening last year a fox was seen on Westminster Bridge looking up at Big Ben.
For peregrine falcons, cities are actually safer than rural cliff dwellings (悬崖栖息地). By 1970 the birds had died out east of the Mississippi because the DDT had made their eggs too thin to support life. That year, scientist Tom Cade of Cornell University began raising the birds for release in cities, for cities afforded abundant food.
Cities can attract wild animals without turning them harmful. The trick is to create habitats where they can be self-sufficient but still be seen and appreciated. Such habitats can even be functional. In San Francisco, the local government is testing different kinds of rainwater control basins to see not only which ones retain (保持) the cleanest water but which will attract the most birds.

At the end of eight grade, our class went to Washington, D.C. For a group of 14-year-olds, this was a big deal!
The first day was so tiring; we could hardly remember where we were and what we were seeing. The next morning, we were off to see monuments (纪念碑)，starting with Washington, Lincoln and Jefferson. We walked along the paths through trees. Then the Wall came into view—the Vietnam Veterans Memorial.
As I moved slowly closer to the Wall, I heard a bagpipe（风笛）in the distance, which seemed to show respect to the lives lost in the jungles of Vietnam .
We continued walking and felt surprised at the number of names carved in the black stone. I was determined to find a soldier with my last name, but my hunt was stopped when a man caught my eyes. He was kneeling(跪着) at the Wall, a single rose at his feet. His head was bowed and he was rubbing his fingers over one name. I thought how sad he was, and then moved on .
After a few minutes I found one with my last name, but my eyes returned to the kneeling man. He was still rubbing his fingers over the same name. He never knew I was watching him, lost in deep sorrow. It was time for me to leave the kneeling man and the Wall. On the way home, I couldn’t help thinking of the kneeling man and his sad face. I wasn’t sure of the effects of war before, but at that moment I realized how much that man suffered from losing his loved one. Maybe he was the only one of so many families who experienced the same .
I never knew the full effects of war until I saw that man. I only know about war from history classes. The kneeling man taught me more about war and the effects it has on people than any history book .
