A few years ago, Paul Gerner began to gather a group of architects in Las Vegas to ask them what it would take to design a public school that used 50 percent less energy, cost much less to build and obviously improved student learning. “I think half of them fell off their chairs,” Gerner says.

Gerner manages school facilities （设施） for Clark County, Nevada, a district roughly the size of Massachusetts. By 2018, 143,000 additional students will enter the already crowded public-education system. Gerner needs 73 new schools to house them. Four architecture teams have nearly finished designing primary school prototypes （样品）; they plan to construct their schools starting in 2009. The district will then assess how well the schools perform, and three winners will copy those designs in 50 to 70 new buildings.

Green schools are appearing all over, but in Clark County, which stands out for its vastness, such aggressive targets are difficult because design requirements like more natural light for students go against the realities of a desert climate. “One of the biggest challenges is getting the right site orientation （朝向）,”Mark McGinty, a director at SH Architecture, says. His firm recently completed a high school in Las Vegas. “You have the same building, same set of windows, but if its orientation is incorrect and it faces the sun, it will be really expensive to cool.”

Surprisingly, the man responsible for one of the most progressive green-design competitions has doubts about ideas of eco-friendly buildings. “I don’t believe in the new green religion,” Gerner says. “Some of the building technologies that you get are impractical. I’m interested in those that work.” But he wouldn’t mind if some green features inspire students. He says he hopes to set up green energy systems that allow them to learn about the process of harvesting wind and solar power. “You never know what’s going to start the interest of a child to study math and science,” he says.

How did the architects react to Gerner’s design requirements?

A. They lost balance in excitement.                B. They showed strong disbelief.

C. They expressed little interest.                     D. They burst into cheers.

C. Design — Assessment — Prototype — Construction.

D. Design — Prototype — Assessment — Construction.

A. The large size.                                          B. Limited facilities.

What does Gerner think of the ideas of green schools?

A. They are questionable.                               B. They are out of date.

C. They are advanced.                                    D. They are practical.

A Love Note to My Mom
When I was a little girl, I would often accompany you as you modeled (T台展示) for fashion photographers. It was years later that I finally understood what role modeling   36  in your life. Little did I know you were   37   every penny you earned to go to   38  school.
I cannot thank you enough for   39  you told me one autumn afternoon when I was nine. After finishing my homework, I wandered into the dining room where you were buried   40  piles of law books. I was   41 . Why were you doing what I do—memorizing textbooks and studying for   42  ? When you said you were in law school, I was more puzzled. I didn’t know Moms   43  be lawyers too. You smiled and said, “In life, you can do anything you want to do.”
As young as I was, that statement kept   44  in my ears. I watched as you faced the   45  of completing your studies, starting companies with Dad, while still being a   46   and a Mom of five kids. I was exhausted just watching you       47 . With your words of wisdom in my   48  mind, I suddenly felt unlimited freedom to dream. My whole world  49 . I set out to live my life filled with  50 , seeing endless possibilities for personal and professional achievements.
Your words became my motto. I   51   found myself in the unique position of being either the first (woman doctor in Maryland Rotary)   52   one of the few women (chief medical reporters) in my field. I gained strength every time I said, “Yes, I’ll try that.”
Encouraged by your   53  , I have forged ahead(毅然前行) with my life’s journey, less afraid to make mistakes, and   54   meeting each challenge. You did it, and now I’m   55   it. Sorry, got to run. So much to do, so many dreams to live.

Much of the water we use comes from snow. Melting snow provides water for rivers, electric power centers and agricultural crops. In the western United States, mountain snow provides up to 75% of all surface water supplies.
Snowfall helps to protect plants and some wild animals from cold, winter weather. Fresh snow is made largely of air trapped among the snow crystals. Because the air has trouble moving, the movement of heat is greatly reduced.
Snow also is known to influence the movement of sound waves. When there is fresh snow on the ground, the surface of the snow takes in, or absorbs, sound waves. However, snow can become hard and flat as it becomes older or if there have been strong winds. Then the snow's surface will help to send back sound waves. Under these conditions, sounds may seem clearer and travel farther.
Generally, the color of snow and ice appears white. This is because the light we see from the sun is white. Most natural materials take in some sunlight. This gives them their color. However, when light travels from air to snow, some light is sent back, or reflected. Snow crystals have many surfaces to reflect sunlight. Yet the snow does take in a little sunlight. It is this light that gives snow its white appearance.
Sometimes, snow or ice may appear to be blue. The blue light is the product of a long travel path through the snow or ice. In simple terms, think of snow or ice as a filter. A filter is designed to reject some substances, while permitting others to pass through. In the case of snow, all the light makes it through if the snow is only a centimeter thick. If it is a meter or more thick, however, blue light often can be seen.
