Kenya is losing an average of 100 of its 2,000 lions each year because of growing human settlements, increasing farming, climate change and diseases, according to the Kenya Wildlife Service (KWS).
“Lions have a special place in Kenyans’ life,” said Paul Udoto, a spokesman for the organization. “Other than being the symbol of national strength, they are among the Big Five, a main attraction for visitors to Kenya.”
There were 2,749 lions in Kenya in 2002 and their population dropped to 2,280 by 2004 and to about 2,000 today, according to KWS figures.
“The fall of the lion population is worrying and every effort needs to be made to make sure that Kenya either protects its population of 2,000 lions at present or increases the numbers to an ecologically (生态上地) acceptable level,” said Mr. Udoto.
“There is no doubt that the numbers are in free fall. I’d be surprised if they even last as long as 20 years,” said Laurence Frank, project director of Living With Lions, a Kenya-based animal protection organization. “When I first came here 30 years ago, I would always hear lions roaring across the land at night and see their tracks in the morning. Now that is very rare.”
“The reason is simple. As the numbers of people grow and the numbers of cows increase, they take up much of the lion’s space. Alongside that there are other ways, including poisoning, to kill lions.”
Animal lovers are making a new strategy to save the animals. Part of the measures will include tracking lions fitted with radio collars (无线电项圈) in the Amboseli area in southern Kenya, close to the border with Tanzania.
Wildlife officials in Tanzania face similar challenges in protecting their lions, but there is far less human encroachment(侵犯) on the animals’ homeland there than in Kenya.

【小题5】D
解析【小题1】结合第一段的because of growing human settlements, increasing farming, climate change and diseases可知没有提到B. too many visitors。
【小题2】概括段意题。结合a main attraction for visitors to Kenya可知答案。
【小题3】推断题。由I’d be surprised if they even last as long as 20 years(如果他们还能活20年的话,我会很惊讶)可知说话人认为如果不采取措施的话,20年后就没有狮子了。
【小题4】主旨大意题。本文是一遍新闻报道,讲述了在Kenya由于rowing human settlements, increasing farming, climate change and diseases的原因使狮子的数量在减少,濒临灭绝。

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. "
