Researchers at Yale, Texas A&M and Boston University predict that by 2030 urban areas will expand by more than 463,000 square miles, or l.2 million square kilometers. That is equal to 20,000 American football fields becoming urban every day for the first three decades of this century.

The growth in urban areas will go with the construction of roads and buildings, water and sanitation facilities, and energy and transport systems that will transform land cover and cities globally. Recent estimates suggest that between $25 trillion(万亿) and $30 trillion will be spent on infrastructure(基础设施) worldwide by 2030, with $100 billion a year in China alone.

"Considering the long life and near unavoidability of infrastructure investments, it will be critical for current urbanization-related policies to consider their lasting impacts," said Karen Seto, lead author of the study. "We have a huge opportunity to shape how cities develop and their environmental  impacts."

Nearly half of the increase in high-probability ----defined as greater than 75 percent ---- urban expansion is forecasted to occur in Asia, with China and India absorbing 55 percent of the regional total. In China, urban- expansion is expected to create a l,l00-mile coastal urban corridor from Hangzhou to Shenyang. In India, urban expansion will be gathered around seven state capital cities, with large areas of low-probability growth forecasted for the Himalaya region where many small villages and towns currently exist.

Africa's urban land cover will grow the fastest, at 590 percent above the 2000 level of 16,000 square miles. Urban expansion win be concentrated in that continent's five regions: the Nile River in Egypt; the coast of West Africa on the Gulf of Guinea; the northern shores of Lake Victoria in Kenya and Uganda and extending into Rwanda and Burundi; the Kano region in northern Nigeria; and greater Addis Ababa, Ethiopia.

"Urban expansion is concentrated in. only a few areas where there are large cities and industry," said Seto. "From the northern shore of Lake Victoria down to Rwanda is also a major hotspot of urban expansion."

In North America, where 78 percent of the total population lives in urban areas, urban land cover will nearly double by 96,000 square miles by 2030.The study also forecasts that 48 of the 221 countries in the study will experience insignificant amounts of urban expansion. "

Years ago, I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing or reading.

     After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, "I wonder why that woman doesn't wash her window. It really looks terrible."

   One bright morning I decided to clean my flat, including washing the window on the inside.

   Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible. Her window was clean!

Then it dawned on me. I had been criticizing (????) her dirty window, but all the time I was watching hers through my own dirty window.

That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings?

Many adults in the United States can remember crying the nursery rhyme in the street "Hot cross buns!" But only a few people realize this was an early form of advertising.

Written advertisements probably began with hieroglyphics more than three thousand years ago, but only a few people could read these symbols. So merchants made signs with pictures or hung their tools over their doors to identify their businesses.

In the time of the Roman Empire, wall paintings were a popular form of advertisement. An ad for a play, or some other performance was painted on part of a building or on a wall around a city. People often advertised a house for rent or a freshwater bath in this way, too.

Today, large wall signs are still used for outdoor advertising. But outdoor advertising is only a small fraction of the total advertising. About forty per -cent of all ads are printed in daily newspapers. Radio commercials also provide this kind of information. Some people think they are the best form of advertising because radio broadcasts reach almost everyone in a nation.

Advertisements in magazines and on television reach many people, too. However, usually only large companies can advertise on a national network, because TV commercials shown across the country can cost many thousands of dollars.

Then there are ads that are almost part of daily living. If you use public transportation, you will see large printed ads, called ear cards, on buses and taxis and in trains. Ads are painted on the trucks that deliver products people are buying or selling.

1.Which is the passage mainly discussing?

A.Modern advertising                     B.Significance of advertising

C.Development of advertising               D.Origin of advertising

2.Which of the following is the original form of advertising?

A.Signs with pictures                      B.Wall signs

C.Street crying                           D.Wall painting

3.Which of the following can best replace the underlined word “hieroglyphics” in Paragraph 2?

A.A signal           B.A signature        C.A symbol          D.A form

4.Why did the merchants make signs with pictures or hang their tools over their doors ?

A.To have their houses decorated.

B.To make their business known by public.

C.To enable people to learn how to read

D.To advertise their houses to rent

5.Radio commercials are the best form of advertising because ____________.

A.they can be heard everywhere in a country

B.they are cheap and fast

C.they are most recently developed

D.they can be understood by those who can neither read nor write
