The world's exploding population signals even more growing pains ahead for already crowded areas. A new United Nations study forecasts that by the year 2000,2 billion persons will be added to the 4.4 billion in the world today.
Even more troubling than the increasing number of inhabitants are the projections of where they will be concentrated. The study by Rafael M. Solos, executive director of the U. N. Fund for Population Activities, notes that by the year 2000:
Nearly 80 percent of all people will live in less developed countries, many hard pressed to support their present populations. That compares with 70 percent today.
In many of these Third World lands metropolises (大城市) will become centers of concentrated urban poverty because of a flood of migration from rural areas.
The bulging(膨胀的) centers mainly in Asia and Latin America, will increasingly become fertile fields for social unrest. More young residents of the urban clusters(一群) will be better educated, unemployed and demanding of a better lifestyle.
To slow the rush to urban centers, countries will have to vastly expand opportunities in the country side, the study suggests. Solos says: "The solution to the urban problem lies as much in the rural areas as in the cities themselves."
Worldwide, the numer of large cities ,will multiply. Now 26 cities have 5 million or more residents each and a combined population of 252 million. By the end of the decade, the number will escalate to 60. with an estimated total of almost 650 million people.
In the last paragraph, the word "escalate" means ______.
A．decrease
B．increase
C．go down
D．decline

You might think that "global warming" means nothing more than a rise in the world's temperature. But rising sea levels caused by it have resulted in the first evacuation (撤离)of an island nation-the citizens of Tuvalu will have to leave their homeland.
During the 20th century, sea level rose 8-12 inches. As a result. Tuvalu has experienced lowland flooding of salt water which has polluted the country's drinking water.
Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.
Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an iuternationa] agreement calling for industrialized nations to reduce their greenhouse gas emissions (导致温室效应的气体排放), which are a main cause of global warming. "By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years," Laupepa told the BBC.
Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.
Tuvalu is not the only country that is vulnerable (易受影响的)to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an "endangered nation".
The text is mainly about ______.
A．rapid changes in earth's temperature
B．bad effects of global warming
C．moving of a country to a new place
D．reasons for lowland flooding

Research findings from Norwegian and Danish scientists released in late 1997 indicate that the world's reindeer are "hot" — radioactive — and are contaminating their owners and minders.
The radiation comes as a result of the 500 atomic bomb tests carried out in the atmosphere by the nuclear nations in the 1950s and 1960s. Long-lived isotopes in the fall-out have built up in Arctic lichens which are the reindeer's staple diet. The reindeer have been found to concentrate the isotopes in their bodies. Animals are affected all over the Arctic, with the most radioactive reindeer in Canada, Alaska and Siberia's Taimyr Peninsula.
Enormous amounts of reindeer meat — some 14,000 tonnes — are eaten in the Arctic each year. Research at the Danish Riso National Laboratory has found that reindeer herders, who consume a lot of the meat, take in 300 times more radiation each year than is the average anywhere in northern Europe. Norway's Radiation Protection Authority estimates that many hundreds of herders have died of cancer as a result.
Meanwhile reindeer are emerging as one of the greatest environmental threats to the Norwegian Arctic. Over-grazing and trampling is causing more damage to the fragile tundra than pollutants from the world's worst-offending factories. Over the last 40 years the number of reindeer in the Norwegian Arctic have doubled, reaching 20 animals per square kilometre, a very high density. Research by the Norwegian and Danish geological surveys and Russia's Kola Science Centre have found that 75 percent of the moss in the Norwegian Arctic and 85 percent of lichen have been "severely damaged" by reindeer. Three-quarters of the area is suffering from soil erosion. By contrast, two of the world's most polluting factories---nickel smelters in Russia's Kola peninsula — have about 10 percent of the moss and 14 percent of the lichen in the area.
Even the Saami people, who own most of the reindeer, admit that the animals may be causing problems. Lars-Ander Baer, vice-president of their council, admitted to a conference on the Arctic environment recently: "We simply don't know how many reindeer the northern part of Norway can take."
Which of the following is NOT a cause of the problem under discussion？
A．Over-grazing.
B．Radioactive contamination.
C．Poaching.
D．Trampling.

The world's population continues to grow. There now are about 4 billion of us on earth. That could reach 6 billion by the end of the century and 11 billion in another 75 years. Experts long have been concerned about such growth Where will we find the food, water, jobs, houses, schools and health care for all these people？
A major new study shows that the situation may be changing. A large and rapid drop in the world's birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations,
Researchers said they found a number of reasons for this. More men and women are waiting longer to get married and are using birth control devices and methods to prevent or delay pregnancy. More women are going to school or working at jobs away from their homes instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population growth. China is one of the nations that has made great progress in reducing its population growth.
China has already cut its rate of population growth by about one half since 1970. China now urges each family to have no more than one child. And it hopes to reach zero population growth, the number of births equaling the number of deaths, by the year 2000.
Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future. And the persons who are working could face much higher taxes to help support the growing number of retired people.
In Paragraph one, the sentence "Experts Dong have been concerned about such growth", the phrase "concerned about" is similar in meaning to______.
A．worried about
B．related to
C．engaged in
D．made a study of

They may not be the richest, but Africans remain the world's staunchest optimists. An annual survey by Gallup International, a research outfit, shows that, when asked whether this year will be better than last, Africa once again comes out on top. Out of 52,000 people interviewed all over the world, under half believe that things are looking up. But in Africa the proportion is close to 60% almost twice as much as in Europe.
Africans have some reasons to be cheerful. The continent's economy has been doing fairly well with South Africa, the economic powerhouse, growing steadily over the past few years. Some of Africa's long-running conflicts, such as the war between the north and south in Sudan and the civil war in Congo, have ended. Africa even has its first elected female head of state, in Liberia.
Yet there is no shortage of downers too. Most of Africa remains dirt poor. Crises in places like Cote d'Ivoire, Sierra Leone and Zimbabwe are far from solved. And the democratic credentials of Ethiopia and Uganda, once the darlings of western donors, have taken a bad knock. AIDS killed over gm Africans in 2005, and will kill more this year.
So is it all just a case of irrational exuberance？ Meril James of Gallup argues that there is, in fact, usually very little relation between the survey's optimism rankings and reality. Africans, this year led by Nigerians, are consistently the most upbeat, whether their lot gets better or not. On the other hand, Greece—hardly the worst place on earth—tops the gloom and doom chart, followed closely by Portugal and France.
Ms James speculates that religion may have a lot to do with it. Nine out of ten Africans are religious, the highest proportion in the world. But cynics argue that most Africans believe that 2006 will be golden because things have been so bad that it is hard to imagine how they could possibly get worse. This may help explain why places that have suffered recent misfortunes, such as Kosovo and Afghanistan, rank among the top five optimists. Moussaka for thought for those depressed Greeks.

A．disparity

UN officials pledged Thursday to bridge the world's digital divide, bringing computers and Internet training to Poorer countries before they fall further behind in technology and wealth. The Digital Service Corps initiative expands on a University of Pennsylvania pilot that sent three professors and 27 students to the West African country of Mall last spring. Four countries will be selected for visits in December.
In partnering with the private Global Technology Organization, the UN Office for Projects Services wants to reduce the gap separating nations with good technology from those without. "There are more Web sites originating here in New York than in all of Africa," said Reinhart Helmke, executive director of the UN agency. "There are more Web sites originating in Finland than in all of Latin America and the Caribbean." Helmke said the digital divide would be better described as a digital chasm. He said the global economy cannot be sustained if some countries are left out.
Neysan Rassekh, founder and president of Global Technology Organization, vowed to tackle the problem "country by country, town by town, citizen by citizen." The initiative carries no funding, however. The UN projects office, as a self-financing agency with a limited budget, will provide only management know-how. Rassekh's group, which organized the University of Pennsylvania group, plans to solicit(恳求) cash and equipment donations. For the Mali project, the university paid airfare and other expenses through fees that students pay to receive academic credit.
Eliminating the global divide won't be easy. Persuading foreign governments to buy computers instead of food can be tough, even though technology can reduce poverty and hunger in the long run, said Hafidh Chaibi, who promotes global access through the World of Knowledge Foundation in Orlando, Fla. Ernest Wilson, an international development specialist at the University of Maryland, said his research found information technology growing by 18 percent a year in developing countries, compared with 23 percent in industrialized nations. That means the gap continues to grow despite improvements through programs from the United Nations, the World Bank, the Markle Foundation and other organizations.
The UN announcement came as world leaders met at the UN Millennium Summit to discuss such challenges as peace, disarmament and access to new technology. Over four weeks in May and June, the University of Pennsylvania volunteers set up four computer centers in Mall and trained 120 residents, mostly students and educators who could then teach others. Organizers are also setting up a Web site to help residents obtain information on education and health. The UN agency and its private partner plan to replicate that effort in 10 to 12 countries a year.
The "digital divide" as is used in the first passage refers to ______.
A．the gap in technology and wealth between poor and rich countries
B．inadequate training which technicians in poorer countries have received
C．the availability of computer and Internet technologies to different nations
D．the difference in the number of Web sites created to poor and rich countries
