The rapid growth of cities worldwide over the next two decades will cause significant risks to people and the global environment, according to analysis.

Researches from Yale and Stanford predict that by 2030 urban areas will expand by 590,000 square miles—nearly the size of Mongolia—to meet the needs of 1.47 billion more people living in urban areas.

“It is likely that these cities are going to be developed in places that are the most biologically diverse,” said Karen Seto, a famous scientist at Yale University. “They are going to be growing and expanding into forests, biological hotspots, savannas(热带稀缺大草原), coastlines—sensitive and vulnerable places.”

Urban areas, they found, have been expanding more rapidly along coasts. “Of all the places for cities to grow, coasts are the most sensitive. People and buildings along the coast are at risk of flooding and other environmental disasters,” said Seto.

The study provides the first estimate of how fast urban areas globally are growing and how fast they may grow in the future. “We know a lot about global patterns of urban population growth, but we know significantly less about how urban areas are changing,” she said. “Changes in land cover associated with urbanization lead to many environmental changes, from habitats loss and agricultural land conversion(转化) to changes in local and regional climate.”

The researchers examined studies that used satellite data to map urban growth and found that from 1970 to 2000 the world’s urban footprint had grown by at least 22,400 square miles—half the size of Ohio.

“This number is numerous, but, in actuality, urban land expansion has been far greater than what our analysis shows because we only looked at the published studies that used satellite data,” said Seto. “We found that 48 of the most populated urban areas have been studied using satellite data, with findings in journals. This means that we’re not tracking the physical expansion of more than half of the world’s largest cities.”

Half of urban land expansion in China is driven by a rising middle class, whereas the size of cities in India and Africa is driven primarily by population growth. “Rising incomes translate into rising demand for bigger homes and more land for urban development, which has a great effect on biodiversity conservations, loss of carbon sinks and energy use.”

1.According to the passage, the most dangerous place for city expansion is the _____.

A．forest            B．desert            C．savannas          D．coastline

2.The underlined word “vulnerable” (in Para. 3) probably means “____”.

A．diverse in plants                        B．beautiful in scenery

C．easily damaged                         D．very productive

3.From Para. 5, we can infer that ____.

A．urbanization is a good way to improve people’s standards of living

B．cities develop very fast and more and more people come to live in cities

C．more and more agricultural farmlands are used to make room for local animals

D．in the past, researchers focused their attention on the expanding urban areas

4.Cities in Africa become bigger and bigger mainly because of their ____.

A．growing population                      B．rising middle class

C．unique living patterns                    D．economic development

The CEO of Apple, Steve Jobs’ story about death
When I was 17, I read a quote that went something like: “If you live each day as if it were your last, someday you’ll most certainly be right.” It made an impression on me, and since then, for the past 33years, I have looked in the mirror every morning and asked myself, “If today were the last day of my life, would I want to do what I am about to do today?”
Remembering that I’ll be dead soon is the most important tool I’ve ever encountered（遇到）to help me make the big choice in life.
About a year ago I was diagnosed with cancer. The doctors told me this was almost certainly a type of cancer that was incurable, and that I would live no longer than three to six months. My doctor advised me to go home and get my affairs in order, which is my doctors’ code for preparing yourself to die.
I lived with that diagnosis all day. I was completely in despair. Later that evening, I had another biopsy（活组织检查）and my wife told me that tumor turned to be curable with surgery. I had the surgery and I’m fine now.
This was the closest I’ve been to facing death. To tell the truth, no one wants to die. And yet death is the destination we all share. No one has ever escaped it. It clears out the old to make room for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away.
Your time is so limited that you shouldn’t waste it repeating someone else’s life. Don’t be trapped by dogma（教条）----which is living with the results of other people’s thinking. Don’t let the noise of others’ opinions drown out your own inner voice. And most importantly, have the courage to follow your heart. It somehow already knows what you truly want to become. Everything else is secondary.

His first successful fight was for the equal rights of black people in South Africa. Then, as the first black president, he fought to unite the country and organize the government. Now Nelson Mandela has set his sights on a new enemy, AIDS.

On March 19 the 82-year-old, former president, hosted his second AIDS-awareness concert. He warned that 25 million people in Africa were already infected with the fatal disease.

Mandela was born in a small village in South Africa in 1918. He was adopted by the chief of his tribe and could have been a chief himself and lived a happy country life.

But he refused to be a chief when his people lived under racial discrimination(歧视). He decided to fight for equal rights for all the people in South Africa. Before 1990, under the country’s Racial Segregation Law, colored and white people lived separately. Black people were treated unfairly even when taking a bus. Blacks had to stand at the back of the bus to make room for white people even when there were only a few of them on board.

For his opposition to the system, Mandela was arrested and spent 27 years in prison. He was freed in 1990 and became the president of the country after the first election were held in which everyone could vote.

Mandela was not only a political fighter who attacked with speeches. He was also a trained boxer and fought in the ring when he was young.

“Although I did not enjoy the violence of boxing, I was interested in how one moved one’s body to protect oneself, how one used a strategy both to attack and retreat”, he wrote in his autobiography.

As a skillful fighter, he chose music as his weapon against AIDS. He hopes to win another victory against AIDS.
