Live Earth Announces 2010 Global Event!

This is the web version of the October 15, 2009 Live Earth email to members. Click here to join and receive bi-weekly updates from Live Earth.

Live Earth is pleased to announce the largest worldwide water initiative(倡议)in history to help fight the global water crisis. The Dow Live Earth Run for Water—to take place on April 18, 2010—will consist of a series of 6 km run/walks (the average distance many women and children walk every day to get water) taking place over the course of 24 hours in countries around the world, featuring concerts and water education activities, raising awareness and funds to help solve the water crisis. Jessica Biel, Alexandra Cousteau, Pete Wentz, Angelique Kidjo and Jenny Fletcher will lend their names and their time in support of this global event.

Water shortage is a major issue affecting countries, communities and families all over the world. One in eight people doesn’t have access to safe, clean drinking water. Communities in Africa, Latin America and Asia suffer 1.8 million deaths every year from diarrheal(腹泻）diseases and the death of 5,000 children each day due to inadequate water infrastructure(基础设施). In these areas, women and children are forced to walk 6 km (3.7 miles) each day to get water that is likely unsuitable for drinking. However, the water crisis is not only limited to developing nations. Adding to these existing issues, the effects of climate change are increasingly impacting both supply and quality of available fresh water throughout the world.

In 60% of European cities with populations greater than 100,000, groundwater is being used faster than it can be replenished(补充). By 2025, two-thirds of the world’s population could be living under water-stressed conditions.

You can help solve the water crisis by participating in the April 18th event. Run/walk registration is now officially open! Sign up now at http://liveearth.org/run.

A 33-year-old financial analyst in California recently quit his job to devote himself to an unpaid job teaching math on the Internet, and his lessons are reaching almost 100,000 people a month. Salman Khan’s voice is heard every day on the net --- by tens of thousands of students around the world who are hungry for help learning math. He has posted 1,200 lessons on YouTube ... lessons that appear on an electronic blackboard, which range from basic addition to advanced mathematics for science and finance. And they are free.

Khan lives in Silicon Valley, with his wife, a doctor, and their new baby. He got the idea for his “Khan Academy” four years ago, when he taught a young cousin how to convert kilograms to grams. With Khan’s help, the cousin got good at math, and Khan began a new career.

Now, Khan records his lessons himself, but he never goes on camera. “It feels like my voice in their head. You’re looking at it and it feels like someone’s over your shoulder talking in your ear, as opposed to someone at the blackboard, which is distant from you,” he said.

When Springfield High School in Palo Alto, California invited Khan to speak in person --- he immediately connected to the students there.

The idea of short lessons that can be played over and over again attracted high school senior Bridget Meaney. She says she had trouble with math in the seventh grade. “I think the teachers are good, but they can’t teach at a speed that’s perfect for everyone,” she said. “I like the idea of learning something in class but then going back and pressing pause or rewind and actually getting a deeper understanding of it.”

Originally, Khan kept his lessons short because of YouTube restrictions. Now, he thinks short is better. “Education researchers now tell me that 10 minutes is how long someone can have a high level of concentration. And anything beyond that and your brain switches off,” he said.

For Khan, teaching math, science, and finance is just the beginning. He says he’s ready to expand his YouTube site to include other subjects as well.

What gave Khan the idea of teaching math online?

A. His success in helping his cousin learn math.

B. His discovery that many students found learning math difficult.

C. A suggestion made to him at a local high school.

D. His interest in Internet teaching.

Why does Khan never go on camera?

A. He’s too shy to show his face on camera.

B. It’s restricted by YouTube for education videos.

C. He wants to keep distance from the viewers.

D. He wants to create a more relaxed learning atmosphere.

From the passage, we know that ________.

A. Khan travels to many schools to promote his lessons

B. Khan plans to include more subjects in the future

C. Khan gives live math lessons every day for free

D. Khan set up the Khan Academy with his wife

Why does Bridget Meaney like Khan’s lessons?

A. Khan teaches seventh grade math better than her teacher.

B. The lessons can be watched repeatedly until fully understood.

C. She can perfectly follow the pace of Khan’s teaching.

D. She cannot concentrate when learning in class.

What does Khan mean by “short is better” in the 6^th paragraph?

A. Keeping the lessons short can ensure better concentration.

B. YouTube recommends short lessons for its site.

C. Short lessons encourage students to return to the website.

D. Students enjoy short mathematics lessons more.

One day, when I was working as a psychologist in England，an adolescent boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had referred him to me. "This boy has lost his family," he wrote. "He is understandably very sad and refuses to talk to others, and I'm very worried about him. Can you help?”

I looked at David and showed him to a chair. How could I help him? There are problems psychology doesn’t have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetically

The first two times we met, David didn't say a word. He sat there, only looking up to look at the children's drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon一in complete silence and without looking at me. It's not easy to cheat in chess, but I admit I made sure David won once or twice.

Usually, he arrived earlier than agreed. took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company. But why did he never look at me?

"Perhaps he simply needs someone to share his pain with," I thought. "Perhaps he senses that I respect his suffering.” Some months later, when we were playing chess, he looked up at me suddenly.

"It’s your turn," he said.

After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.

Maybe I gave David something. But I also learned that one一without any words一can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.

36. When he first met the author, David .

A. felt a little excited

B. walked energetically

C. looked a little nervous

D. showed up with his teacher

37. As a psychologist, the author .

A. was ready to listen to David

B. was skeptical about psychology

C. was able to describe David's problem

D. was sure of handling David's problem

38．David enjoyed being with the author because he________.

A．wanted to ask the author for advice

B．need to share sorrow with the author

C．liked the children’s drawings in the office

D．bear the author many times in the chess game

39．What can be inferred about David?

A．He recovered after months of treatment.

B．He liked biking before he lost his family.

C．He went into university soon after starting to talk.

D．He got friends in school before he met the author.

40．What made David change?

A．His teacher’s help.

B．The author’s friendship.

C．His exchange of letters with the author.

D．The author’s silent communication with him.

Crossing Texas and Mexico, the Big Bend region is high in biodiversity(生物的多样性). It’s a place so untamed that if something doesn’t bite, stick, or sting, it’s probably a rock.

You know you have arrived in the heart of the Chihuahuan Desert when it feels as if you have fallen off the edge of the earth and into the rabbit hole. Nothing is as it appears. Moths (蛀虫) are the size of birds. Are those twin pillars (柱) of black rock (a landmark known as Mule Ear Peaks) ten miles (16 kilometers) away or fifty (80 kilometers)? Visibility (能见度) reaches more than a hundred miles on a clear day, and since there are few roads or buildings to use as milestones, distance is difficult to judge.

This is a place where water runs uphill, where rainbows have to wait for rain. The line between myth (虚构的故事) and reality is unclear. Stare long enough at the Chisos Mountains or the Sierra del Carmen, the two mountain ranges, known as sky islands, which lie on the land, and they rise and float above the plain.

The vast Chihuahuan Desert is a land of no people. There is always the chance you’ll die of thirst. The “You Can Die”possibilities are endless, and keep some visitors — 350,000 a year to Big Bend National Park, built in 1944 — from coming back. Those who do return are left to think of the remarkable courage of the brave few who have managed to survive in this terrible environment.

1.The underlined word“untamed”in Paragraph 1 means“________”.

A．untouched

B．wild

C．unchanged

D．fresh

2.Why do the twin pillars of black rock seem ten or fifty miles away?

A．They were put so far away.

B．They lie across the Chihuahuan Desert.

C．It is difficult to judge the distance, with few milestones.

D．One lies in the Chisos Mountains, the other in the Sierra del Carmen.

3.How many years are there since the Big Bend National Park was built?

A．350,000 years.

B．350 years.

C．66 years.

D．44 years.

4.What is the passage mainly about?

A．The natural wonders of the Chihuahuan Desert.

B．Everything you see is not what it seems in the Chihuahuan Desert.

C．The terrible environment of deserts in Texas and Mexico.

D．A special place where none who go can return.

5.What can we learn from the last paragraph?

A．There are all kinds of living things in the Chihuahuan Desert.

B．No people live in the Big Bend region.

C．Nothing is as it appears in the Big Bend region.

D．Traveling in the Big Bend region is dangerous.
