Passage One
The Urbanization — migration away from the suburbs to the city center — will be the biggest real estate trend in 2015, according to a new report.
The report says America’s urbanization will continue to be the most significant issue affecting the industry, as cities across the country imitate the walkability and transit-oriented development making cities like New York and San Francisco so successful.
As smaller cities copy the model of these “24-hour cities，”tfiore affordable versions of these places will be created. The report refers to this as the coming of the “18-hour city，”，and uses the term to refer to cities like Houston, Austin, Charlotte, and Nashville, which are “positioning themselves as highly competitive, in terms of livability, employment offerings, and recreational and cultural facilities.”
Another trend that looks significant in 2015 is that America’s largest population group, Millennials (千禧一代)，will continue to put off buying a house. Apartments will retain their appeal for a while for Millennials, haunted by what happened to home-owning parents.
This trend will continue into the 2020s, the report projects. After that, survey respondents disagree over whether this generation will follow in their parents，footsteps, moving to the suburbs to raise families, or will choose to remain in the city center.
Another issue affecting real estate in the coming year will be America’s failing infrastructure. Most roads, bridges, transit, water systems, the electric grid, and communications networks were installed 50 to 100 years ago, and they are largely taken for granted until they fail.
The report’s writers state that America’s failure to invest in infrastructure impacts not only the health of the real-estate market, but also our ability to remain globally competitive.
Apart from the specific trends highlighted above, which cause some investors to worry, the report portrays an overall optimism borne by the recent healthy real-estate “upcycle” and improving economy. Seventy-four percent of the respondents surveyed report a “good to excellent” expectation of real-estate profitability in 2015. While excessive optimism can promote bad investment patterns, resulting in a real- estate “bubble,” the report’s writers downplay that potential outcome in that it has not yet occurred.
According to the new report, real estate development in 2015 will witness_______ .
A.an accelerating speed
B.a shift to city centers
C.a new focus on small cities
D.an ever-increasing demand
Why are Millennials reluctant to buy a house？A.They can only afford small apartments
B.The house prices are currently too high
C.Their parents' bad experience still haunts them
D.They feel attached to the suburban environment
What characterizes “24-hour cities” like New York？A.People can live without private cars
B.People are generally more competitive
C.People can enjoy services around the clock
D.People are in harmony with the environment
What might hinder real estate development in the U.S.？A.The continuing economic recession in the country
B.The lack of confidence on the part of investors
C.The fierce global competition
D.The worsening infrastructure
How do most of the respondents in the survey feel about the U.S. real-estate market in 2015？A.Pessimistic
B.Hopeful
C.Cautious
D.Uncertain

Most of these megacities are in developing countries that are struggling to cope with both the speed and the scale of human migration. Estimates of the future spread of urbanization are based on the observation that in Europe, and in North and South America, the urban share of the total population has stabilized at 75%--85%. If the rest of the world follows this path it is expected that in the next decade an extra 100 million people will join the cities of Africa, and 340 million the cities of Asia: the equivalent of a new Bangkok every two months. By 2030 nearly two-thirds of the world's population will be urban.
In the long run, that is good news. If countries now industrialising follow the pattern of those that have already done so, their city-dwellers will be both more prosperous and healthier. Man is gregarious species, and the Words "urbane" and "civilised" both derive from the advantages of living in large settlements.
History also shows, though, that the transition can be uncomfortable. The slums of Manchester were, in their time, just as awful as those of Nairobi today. But people moved there for exactly the same reason: however nasty conditions seemed, the opportunities of urban life outstripped those of the countryside. The question is how best to handle the change.
If there is one thing that everybody agrees on, it is that urbanization is unstoppable. Migrants attempting to escape poverty, and refugees escaping conflict, are piling into cities in what the executive director of UN-HABITAT, Anna, Tibailjuka, describes as "premature urbanization."
Dr Tibaijuka believes it might be possible to slow the pace of migration from the countryside with policies that enhance security and rural livelihoods. There is room for debate, though, over whether better rural development in any form. can seriously slow the pace of urbanisation -- or even whether such a slowdown would be a good thing.
Michael Mutter, an urban planning adviser at the British government's Department for International Development (DFID), says that the relevant indicators suggest that in many countries the effective "carrying capacity" of rural areas has been reached. As happened in Europe in the 18th century, population growth and technological improvements to agriculture are creating a surplus population. That surplus has to go somewhere to earn its living.
Indeed, some people go so far so to argue that governments, international donors and aid agencies spend too much on rural development and neglect the cities. Most countries have a rural development policy, but only a few have urban ones. DFID, for example, spends only 5% of its budget directly on urban development. Moreover, these critics point out that, although rural areas often have worse sanitation, illiteracy and homelessness than cities, such figures are deceptive. Being illiterate, homeless or without access to a flush toilet are far more serious problems in a crowded city than in the countryside.
Of the many lessons being learnt from past urban-development failures, one of the most important is that improvements must involve local people in a meaningful way. Even when it comes to the poorest slumdwellers, some governments and city authorities are realizing that people are their own greatest assets. Slumdwellers International is a collection of "grassroots" federations of people living in slums. Its idea is simple. Slum-dwellers in a particular place get together and form. a federation to strengthen local savings and credit schemes, and to lobby for greater co- operation with the authorities. Such federations are having a big impact
A．the side effects of urbanization
B．megacities in developing countries
C．the causes behind immigration to cities
D．ways to slow down the pace of immigration
