单选题In most American cities, the rent for a one-bedroom apartment was $250 or more per month in recent years. In some smaller cities such as Louisville, Kentucky or Jacksonville, Florida the rent was less, but in larger cities it was more. For example, if you lived in Los Angeles, you had to pay $400 or more to rent a one-bedroom apartment, and the same apartment rented for $625 and up in Chicago. The most expensive rents in the U. S. were in New York City, where you had to pay at least $700 a month to rent a one-bedroom apartment in most parts of the city. Renters and city planners are worried about the high cost of renting apartments. Many cities now have rent control laws to keep the cost of renting low. These laws help low-income families who cannot pay high rents. Rent controls in the United States began in 1943 when the government imposed rent controls on all American cities to help workers and the families of soldiers during World War Ⅱ. After the war, only one city—New York—continued these World War Ⅱ controls. Recently, more and more cities have returned to rent controls. At the beginning of the 1980s, nearly one fifth of the people in the United States lived in cities with rent-control laws. Many cities have rent-control laws, but why are rents so high? Builders and landlords blame rent controls for the high rents. Rents are high because there are not enough apartments to rent, and they blame rent controls for the shortage of apartments. Builders want more money to build more apartment buildings, and landlords want more money to repair their old apartment buildings. But they cannot increase rents to get this money because of the rent-control laws. As a result, landlords are not repairing their old apartments, and builders are not building new apartment buildings to replace the old apartment buildings. Builders are building apartments for high-income families, not low income families, so low-income families must live in old apartments that are in disrepair. Builders and landlords claim that rent-control laws really hurt low income families. Many renters disagree with them. They say that rent control is not the problem. Even without rent controls, builders and landlords will continue to ignore low-income housing because they can make more money from high-income housing. The only answer, they claim, is more rent controls and government help for low-income housing.

单选题PERPLEXED: CLARIFICATION

单选题Passage 2 Low-level slash-and-bum farming doesn't harm rainforest. On the contrary, it helps farmers and improves forest soils. This is the unorthodox view of a German soil scientist who has shown that burnt clearings in the Amazon, dating back more than 1 000 years, helped create patches of rich, fertile soil that farmers still benefit from today. Most rainforest soils are thin and poor because they lack minerals and because the heat and heavy rainfall destroy most organic matter in the soils within four years of it reaching the forest floor. This means topsoil contains few of the ingredients needed for long-term successful farming. But Bruno Glaser, a soil scientist of the University of Bayreuth, has studied unexpected patches of fertile soils in the central Amazon. These soils contain lots of organic matter. Glaser has shown that most of this fertile organic matter comes from "black carbon"—the organic particles from camp fires and charred (烧成炭的) wood left over from thousands of years of slash-and-burn faring." The soils, known as Terra Preta, contained up to 70 times more black carbon than the surrounding soil," says Glaser. Unbumt vegetation rots quickly, but black carbon persists in the soil for many centuries. Radiocarbon dating shows that the charred wood in Terra Preta soils is typically more than 1000 years old. "Slash-and-burn farming can be good for soils provided it doesn't completely burn all the vegetation, and leaves behind charred wood," says Glaser. "It can be better than manure (粪肥) ." Burning the forest just once can leave behind enough black carbon to keep the soil fertile for thousands of years. And rainforests easily regrow after small-scale clearing. Contrary to the conventional view that human activities damage the environment, Glaser says,"black carbon combined with human wastes is responsible for the richness of Terra Preta soils." Terra Preta soils turn up in large patches all over the Amazon, where they are highly prized by farmers. All the patches fall within 500 square kilometers in the central Amazon. Glaser says the widespread presence of pottery confirms the soil's human origins. The findings add weight to the theory that large areas of the Amazon have recovered so well from past periods of agricultural use that the regrowth has been mistaken by generations of biologists for "virgin" forest. During the past decade, researchers have discovered hundreds of large earth works deep in the jungle. They are up to 20 meters high and cover up to a square kilometer. Glaser claims that these earth works, built between AD 400 and 1400, were at the heart of urban civilizations. Now it seems the richness of the Terra Preta soils may explain how such civilizations managed to feed themselves.
