One thing the tour books don’t tell you about London is that 2000 of its residents are foxes. They ran away from the city about two centuries ago after developers and pollution moved in . But now that the environment is clear the foxes have come home. “The number and variety of wild animals in urban areas is increasing” says Comer Jones. A survey of the wildlife in New York’s Central Park last year counted 14 species of mammals. A similar survey conducted in the 1890s counted only five species. Several changes have brought wild animals to the cities. Foremost 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 have been created. The Greater London Council last year spent￡750,000 buying land and building 10 permanent wildlife refuges in the city. As a result many birds are now living in the city. For peregrine falcons cities are actually safer than rural cliff dwellings (栖息地). By 1970 the birds had died out east of the Mississippi because of the DDT, which 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 which afforded plenty of 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 kinks of rainwater control basins to see not only which ones retain the cleanest water but which will attract the most birds.

Abby Subark is a mother of two from Boston. “For my kids, I’m nervous. I don’t know if they’ll be able to achieve their American dream.” She may be right. More than hard work or education, the best way to get rich in America is to be born rich.
It is the case that somebody who is in the upper third of income, poor scores, in the bottom on tests when they are in eighth grade, is more likely to go to college and finish college than a poor kid with the top scores. That’s what the working persons’  children are up against.
The Economic Policy Institute finds it would take a poor couple with 2 children 9 or 10 generations to achieve middle class status. That’s about 200 years. The hallmark (特征) of American opportunity has always been the ability to do better than your parents. But compared with similar developed countries, the United States ranks fifth out of six for so-called intergenerational mobility (变动).
If you look at the mechanisms (机制) for upward mobility that were so readily available 50 years ago, they are becoming out of reach, like plentiful factory jobs with good wages and affordable education and health care.
White families are twice as likely as blacks to be upwardly mobile. For most people in America today, where you end up depends on where you start.
If you started in the middle-income class, about 40 to 45 percent of what you are making right now is due to the fact that your parents were in the middle-income class. The rest is up to you.
But for the millions of people who find themselves below the poverty line and the millions more who are the working poor, their starting point for the American dream leaves them painfully far away from the middle class.
【小题1】The main idea of the passage is _______.

Seth DeBolt is a plant scientist at the University of Kentucky US. He and other scientists wanted to find a source of fuel that poor people in rural areas of developing countries could use to make electricity.
The United Nations Development Program says a billion and a half people have no electricity. A billion others have an undependable supply.
Professor DeBolt went on a study trip to rural Indonesia. He saw that there was very little waste in the use of agricultural products. Everything that farmers grew was used for something. Even the remains of fruit that people did not eat were fed to chickens.
Little waste meant there was little that could be used for fuel. Growing a separate fuel crop would take land away from food crops. That was something Professor DeBolt did not want to do.
DeBOLT said, "The people at most risk with respect to energy poverty, typically they're the same people who have food insecurity issues as it is. And then any change in availability would be most damaging to that group of people."
But he found one item that was in plentiful supply and would not create competition between food and fuel. Coconut shells are generally thrown out. Yet Professor DeBolt says it has an "excellent" heating value. All someone needs is a way to release that energy.
DeBolt says he and his team see possibilities for coconut power. "Coconuts are growing here and these are the areas where there is possibility for energy poverty to be eased at least in part by these small-scale production systems."
The researchers say these systems could provide as much as thirteen percent of the energy needs of a country like Indonesia. Other tropical countries with large crops of coconuts and similar fruit could benefit, as well.
But DeBolt says this is not a perfect solution. There are technical questions, like how to safely deal with the dangerous waste produced in the process. And there needs to be money to get these projects started.

GU Zhaodi, 60, had taken water for granted for years. In fact, no one in the beautiful lake city of Wuxi, Jiangsu Province had bothered to spare a thought on water.

    But all that changed dramatically overnight last month when taps in the city ran dry. Due to a blue-green algae(藻类)  outbreak in Taihu Lake, China’s third largest freshwater lake and the source of drinking water for 4 million Wuxi residents(居民),water from the city’s taps became dark and smelly.

   “I can’t believe there is no water for drinking, let alone cooking and washing,” said Ｇu.

   The lake was blanketed with the algae, giving off a strong smell of rotting meat. A stone thrown into it took a long time to sink. Experts said that algae usually boom because of hot water and rich chemicals like phosphor(磷)in the water.

   “High temperature and a lack of rain in the past few months helped the growth of algae,” said Zhang Lijun, an official from the State Environment Protection Administration. “However, pollution from human activity should be most blamed for the disaster.”

    Taihu Lake is surrounded by many small factories, which sprang up in the 1980s.Inthe 1990s,many foreign-funded(外资的) companies joined in. The industries prospered(繁荣)，Wuxi has grown into one of the wealthiest cities in East China.

    But that came at the price of pollution. The lake was treated like a waste dump(垃圾堆)，with factories emptying industrial waste and untreated sewage(污水)into it.

    Although, after the government's effort, life in the city has gone back to normal, the one-week crisis（危机）rang a bell for the government and local people.” It’s time to rebuild the beauty of nature, or our lives will be at risk,” said Gu.

   “A safe environment comes first. Economic growth will be nothing without fresh water to drink and clean air to breathe.” said China Daily.
