　　大學(xué)體驗(yàn)英語(yǔ)綜合教程3聽力：Care for Our Mother Earth

　　(Dr. McKinley of Awareness Magazine interviews a group of experts on environmental issues.)

　　Dr. McKinley: What do you think is the biggest threat to the environment today?

　　Aman Motwane: The biggest threat to our environment today is the way we, as human beings, see our environment. How we see our environment shapes our whole world.

　　Most of us see everything as independent from one another. But the reality is that everything is part of one interconnected, interrelated whole. For example, a tree may appear isolated, but in fact it affects and is affected by everything in its environment - sunshine, rain, wind, birds, minerals, other plants and trees, you, me. The tree shapes the wind that blows around it; it is also shaped by that wind. Look at the relationship between the tree and its environment and you will see the future of the tree.

　　Most of us are blind to this interconnectedness of everything. This is why we don't see the consequences of our actions. It is time for each of us to open our eyes and see the world as it really is - one complete whole where every cause has an effect.

　　Dr. McKinley: Hello Dr. Semkiw. In your research, what environmental issues do you find most pressing?

　　Walter Semkiw: Two environmental issues that we find most pressing are deforesting and global warming. Mankind has now cut down half of the trees that existed 10,000 years ago. The loss of trees upsets the ecosystem as trees are necessary to build topsoil, maintain rainfall in dry climates, purify underground water and to convert carbon dioxide to oxygen. Trees bring water up from the ground, allowing water to evaporate into the atmosphere. The evaporated water then returns as rain, which is vital to areas that are naturally dry. Areas downwind of deforested lands lose this source of rainfall and transform into deserts.

　　Global warming results from the burning of fossil fuels, such as petroleum products, resulting in the release of greenhouse gasses into the atmosphere. Carbon dioxide and other greenhouse gasses then resulting in the trap heat, resulting in warming of our atmosphere.

　　Dr. McKinley: Mr. Nacson, thanks for participating all the way from Australia! What do you suggest the readers of Awareness Magazine can do to help the environmental problem?

　　Leon Nacson: The simplest way to help the environment is not to impact on it. Tread as lightly as you can, taking as little as possible, and putting back as much as you can.

　　Dr. McKinley: What is your specific area of concern regarding the current and future state of the environment?

　　Leon Nacson: Air and water pollution are our Number One priorities. It is hard to understand that we are polluting the air we breathe and the water we drink. These are two elements that are not inexhaustible, and we must realize that once we reach the point of no return, there will be nothing left for future generations.

　　Dr. McKinley: Mr. Desai, what an honor it is to have this opportunity to interview you. Can you please share your wisdom with our readers and tell us where you see the environmental crisis heading?

　　Amrit Desai: We are not separate from the problem. We are the problem. We live divided lives. On one hand, we ask industries to support our greed for more and more conveniences, comfort and possessions. We have become addicted consumers, which causes industrial waste. At the same time, we ignore our connection between our demands and the exploitation of Mother Earth. When we are greedy for more than what we need for our well being, we always abuse the resources of our body and the earth.

　　We are nurtured by the healthy condition of Mother Earth. In humans, if the mother is ailing, the child suffers. We are the cause of the ailing planet and we are the victims.

　　Dr. McKinley: In closing, I thank all of the participants. I have learned a great deal about what I can do as an individual to help the environment.

　　I hope these interviews encourage the readers of Awareness Magazine to take action and develop your own strategy. Too many of us just sit back and say "I'll let the experts deal with it." Meanwhile, we are killing the planet. My aim of this interview is to show how one person can make a difference. Thanks to all for offering your wisdom.

　　大學(xué)體驗(yàn)英語(yǔ)綜合教程3聽力：Frog Story

　　A couple of odd things have happened lately.

　　I have a log cabin in those same woods of Northern Wisconsin. I built it by hand and also added a greenhouse to the front of it. It is a joy to live in. In fact, I work out of my home doing audio production and environmental work. As a tool of that trade I have a computer and a studio.

　　I also have a tree frog that has taken up residence in my studio.

　　How odd, I thought, last November when I first noticed him sitting atop my sound board over my computer. I figured that he (and I say he, though I really don't have a clue if she is a he or vice versa) would be more comfortable in the greenhouse. So I put him in the greenhouse. Back he came. And stayed. After a while I got quite used to the fact that as I would check my morning email and on-line news, he would be there with me surveying the world.

　　Then, last week, as he was climbing around looking like a small gray/green human, I started to wonder about him.

　　So, there I was, working in my studio and my computer was humming along. I had to stop when Tree Frog went across my view. He stopped and turned around and just sat there looking at me. Well, I sat back and looked at him. For five months now he had been riding there with me and I was suddenly overtaken by an urge to know why he was there and not in the greenhouse, where I figured he'd live a happier frog life.

　　"Why are you here", I found myself asking him.

　　As I looked at him, dead on, his eyes looked directly at me and I heard a tone. The tone seemed to hit me right in the center of my mind. It sounded very nearly like the same one as my computer. In that tone I could hear him "say" to me, "Because I want you to understand". Yo. That was weird. "Understand what?", my mind jumped in. Then, after a moment of feeling this communication, I felt I understood why he was there. I came to understand that frogs simply want to hear other frogs and to communicate. Possibly the tone of my computer sounded to him like other tree frogs.

　　Interesting.

　　I kept working. I was working on a story about global climate change and had just received a fax from a friend. The fax said that the earth is warming at 1.9 degrees each decade. At that rate I knew that the maple trees that I love to tap each spring for syrup would not survive for my children. My beautiful Wisconsin would become a prairie by the next generation.

　　At that moment Tree Frog leaped across my foot and sat on the floor in front of my computer. He then reached up his hand to his left ear and cupped it there. He sat before the computer and reached up his right hand to his other ear. He turned his head this way and that listening to that tone. Very focused. He then began to turn a very subtle, but brilliant shade of green and leaped full force onto the computer.

　　And then I remembered the story about the frogs that I had heard last year on public radio. It said frogs were dying around the world. It said that because frog's skin is like a lung turned inside out their skin was being affected by pollution and global climate change. It said that frogs were being found whose skin was like paper. All dried up. It said that frogs are an "indicator species". That frogs will die first because of the sensitivity.

　　Then, I understood.

　　The frogs have a message for us and it is the same message that some sober folks have had for us. "There are no more choices." We have reached the time when we must be the adults for the planet, for the sake of the future generations of human and for frogs.

　　Because we are related.

　　Then I understood that there are no boundaries, that there is no more time.

　　That we, for the sake of our relatives must act now.

　　And then I understood, not only why the frog was there, but, also why I am here

　　大學(xué)體驗(yàn)英語(yǔ)綜合教程3聽力：Einstein's Compass

　　Young Albert was a quiet boy. "Perhaps too quiet", thought Hermann and Pauline Einstein. He spoke hardly at all until age 3. They might have thought him slow, but there was something else evident. When he did speak, he'd say the most unusual things. At age 2, Pauline promised him a surprise. Albert was excited, thinking she was bringing him some new fascinating toy. But when his mother presented him with his new baby sister Maja, all Albert could do is stare with questioning eyes. Finally he responded, "where are the wheels?"

　　When Albert was 5 years old and sick in bed, Hermann Einstein brought Albert a device that did stir his intellect. It was the first time he had seen a compass. He lay there shaking and twisting the odd thing, certain he could fool it into pointing off in a new direction. But try as he might, the compass needle would always find its way back to pointing in the direction of north. "A wonder," he thought. The invisible force that guided the compass needle was evidence to Albert that there was more to our world that meets the eye. There was "something behind things, something deeply hidden."

　　So began Albert Einstein's journey down a road of exploration that he would follow the rest of his life. "I have no special gift," he would say, "I am only passionately curious."

　　Albert Einstein was more than just curious though. He had the patience and determination that kept him at things longer than most others. Other children would build houses of card up to 4 stories tall before the cards would lose balance and the whole structure would come falling down. Maja watched in wonder as her brother Albert methodically built his card buildings to 14 stories. Later he would say, "It's not that I'm so smart, it's just that I stay with problems longer."

　　One advantage Albert Einstein's developing mind enjoyed was the opportunity to communicate with adults in an intellectual way. His uncle, an engineer, would come to the house, and Albert would join in the discussions. His thinking was also stimulated by a medical student who came over once a week for dinner and lively chats.

　　At age 12, Albert Einstein came upon a set of ideas that impressed him as "holy." It was a little book on Euclidean plane geometry. The concept that one could prove theorems of angles and lines that were in no way obvious made an "indescribable impression" on the young student. He adopted mathematics as the tool he would use to pursue his curiosity and prove what he would discover about the behavior of the universe.

　　He was convinced that beauty lies in the simplistic. Perhaps this insight was the real power of his genius. Albert Einstein looked for the beauty of simplicity in the apparently complex nature and saw truths that escaped others. While the expression of his mathematics might be accessible to only a few sharp minds in the science, Albert could condense the essence of his thoughts so anyone could understand.

　　For instance, his theories of relativity revolutionized science and unseated the laws of Newton that were believed to be a complete description of nature for hundreds of years. Yet when pressed for an example that people could relate to, he came up with this: "Put your hand on a hot stove for a minute and it seems like an hour. Sit with a pretty girl for an hour and it seems like a minute. THAT's relativity."

　　Albert Einstein's wealth of new ideas peaked while he was still a young man of 26. In 1905 he wrote 3 fundamental papers on the nature of light, a proof of atoms, the special theory of relativity and the famous equation of atomic power: E=mc2. For the next 20 years, the curiosity that was sparked by wanting to know what controlled the compass needle and his persistence to keep pushing for the simple answers led him to connect space and time and find a new state of matter.

　　What was his ultimate quest?

　　"I want to know how God created this world.... I want to know His thoughts; the rest are details."
