More than 200 scientists have completed a twoyear study to identify the most natural and undeveloped areas on Earth. Their findings are reported in a new book called Wilderness：Earth’s Last Wild Places. The book describes 37 wilderness areas around the world. Each has an area greater than 10,000 square kilometers. The study considered only areas where at least 70% of all plants are native.
North and South America are home to the largest number of wilderness areas. There are 16 such areas, from southern Argentina to Alaska and northern Canada. Africa has 8 wilderness areas, including the thick forests and the grasslands. Australia and New Guinea (几内亚) share 6 areas. Europe has 3 areas and Asia has 2.The Arabian Desert and Antarctica also are considered wilderness areas.
The largest wilderness area is the Boreal Forest (北方森林)．It extends for 16million square kilometers south of the Arctic Circle. The Boreal Forest extends across Alaska, Canada, northern Europe and Russia. The smallest of the 37 wilderness areas is the Sundarbans. It is the world’s largest tidal mangrove forest (红树林)．It covers 10,000 square kilometers of land at the mouth of the Ganges River in India and Bangladesh (孟加拉国)．
The study found that wilderness areas cover about 46% of the Earth’s land surface. However, they are home to less than 2.5% of the world’s population. Nineteen of the wilderness areas have only about one person for each square kilometer. Native people usually live in these areas.
Wilderness areas help to influence the world’s weather systems and rainfall. They are also home to many plants and animals. Population growth and the spread of agriculture and mining operations threaten wilderness areas. But just 7% of all such areas have some form of official protection.

In 1973, Merkel went to the University of Leipzig, where she studied physics. At 32, she got her doctor’s degree in physics.
She stepped_into_politics in 1989.In her first big political job as Minister for the Environment in 1994, her scientific background and strong will proved very useful. In 2005 she became Germany’s Chancellor. She has been reelected to a second term as German Chancellor on September 27, 2009.
Through her political career, Merkel’s persistence (坚持) and patience helped her a lot. “She’s bright and openminded,” said Hubert Markl. “She is the person who wants to know exactly what is going on, and how never giving up will influence our society and future.”

Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked．
Perhaps the best answer lies in our genetic makeup（基因构成）as human beings．What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival．Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible．
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for．Without knowledge, we may be completely destroyed by the danger．With knowledge, we can lessen its effects．
Exploration also allows minerals and other potential （潜在的）resources to be found．Even if we have no immediate need of them, they will perhaps be useful later．Resources may be more than physical possessions．Knowledge or techniques have been acquired through exploration．The techniques may have medical applications which can improve the length or quality of our lives．We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems．Even non-stick pans and mirrored sunglasses are by-products （副产品）of technological developments in the space industry!
While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us．While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers．The danger exists, but knowledge can help human being to survive．Without the ability to reach out across space, the chance to save ourselves might not exist．
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets．It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future．
1.Why does the author mention the questions in Paragraph1?
A．To express his doubts． B．To compare different ideas．
C．To introduce points for discussion． D．To describe the conditions on Earth．
2.What is the reason for exploring space based on Paragraph2?
A．Humans are nature-born to do so． B．Humans have the tendency to fight．
C．Humans may find new sources of food． D．Humans don't like to stay in the same place．
3.The underlined word "spin-offs" in Paragraph 4 probably refers to______．
A．survival chances B．potential resources C．unexpected benefits D．physical possessions
4.What makes it possible for humans to live on other planets?
A．Our genetic makeup． B．Resources on the earth．
C．The adaptive ability of humans． D．By-products in space exploration．
5.Which of the statements can best sum up the passage?
A．Space exploration has created many wonders．
B．Space exploration provided the best value for money．
C．Space exploration can benefit science and technology.
D．Space exploration may help us avoid potential problems on Earth.
Growing up, I wanted to be just like my mom. She was kind. People always seemed to feel comfortable in her presence. For years, she was a volunteer in our community. I loved going to the local nursing home with her where she taught a ceramic class.
On one summer day, Mama told me to get changed and meet her at the car.
I had planned to spend the day at the lake with friends. Why did she have to ruin everything? I imagined the cool lake water. Irritated, I climbed into the car and slammed the door shut. We sat in silence. I was too upset to make conversation.
“Tasha, would you like to know where we are going?” Mama asked calmly.
“No,” I said.
“We are going to volunteer at a children’s shelter today. I have been there before and I think it would benefit you,” she explained.
When we reached the shelter, Mama rang the doorbell. Moments later, we were greeted by a woman. She led us to the front room where all of the children were playing. I noticed a baby whose body was scarred with iron marks. I was told it was because she wouldn’t stop crying. The majority of the children had noticeable physical scars. Others hid their emotional wounds.
As I took in my surroundings, I felt a gentle tug on my shirt. I looked down to see a little girl looking up at me. “Hi. You want to play dolls with me?” she asked. I looked over at Mama for reinforcement. She smiled and nodded. I turned back and said, “Sure.” Her tiny hand reached up and held mine, as if to comfort me.
My mom taught me a valuable lesson that summer. I returned to the shelter with her several times. During those visits, some of the children shared their troubled pasts with me and I learned to be grateful for what I had. Today as I strive to instill (逐渐灌输) these values in my own child, I reflect back to that experience. It was a time that I will never forget.
