[Q]: Article: Overlooking the swollen banks of the Missouri River at Omaha's riverfront landing, one scientist has an important explanation for the past three months of flooding .While many consider the flood to be man-made, a result of water released by the US. Army Corps of Engineers upriver, his theory aims to look deeper into the root of the problem. "The Missouri River is flooding," said Dr. James Hansen, Director of NASA's Goddard Institute for Space Studies, during a visit to Omaha on Tuesday."We've had floods that usually only happen once in every hundred years a couple of times on the Missouri River recently. That's one of the expected consequences of the increasing level of atmospheric carbon dioxide." Hansen, who is considered to be one of the world's leading experts on global warming , said the Missouri River is an example of how global warming is affecting the earth ."Unless you do statistics ,and you see that the frequency of these events is changing , it's not so easy to see that changes are occurring , because the climate system has large inertia ,"he said . Hansen explained, "The ocean is four kilometers deep, and the ice sheets are two or three kilometers thick , so they don't respond immediately as we begin to change the atmospheric composition .We've only experienced about half of the warming that will be caused by the gases already in the atmosphere .The full effect is going to be felt by our children and grandchildren .And if we continue to increase the amount of CO2, the effect will be even larger." Hansen drew a comparison, "If we spend more money than what we're taking in , we're leaving a debt for our children and grandchildren to deal with ."According to Hansen, the responsibility lies in effective policy making to fight against global warming .That includes a gradual reduction in carbon emissions .Hansen suggests that a rising price be placed on carbon emissions, which should be collected from the fossil fuel companies at the first sale . Without effective measures taken by the government, Hansen said the public could expect more of the recent extreme weather patterns,, including more severe droughts and floods in the decades ahead .

[Q]: Article: I made a promise to myself on the way down to the vacation beach cottage. For two weeks I would try to be a loving husband and father. Totally loving. No ifs, ands or buts. The idea had come to me as I listened to a talk on my car radio. The speaker was quoting a Biblical passage about husbands and their wives. Then he went on to say, "Love is an act of will. A person can choose to love." To myself, I had to admit that I had been a selfish husband. Well, for two weeks that would change. And it did. On arriving at the beach cottage, I kissed Evelyn meeting me at the door and said, "That new yellow sweater looks great on you." "Oh, Tom, you noticed", she said, surprised and pleased. Maybe a little puzzled. After the long drive, I wanted to sit and read. Evelyn suggested a walk on the beach. I started to refuse, but then I thought, "Evelyn's been alone here with the kids all week and now she wants to be alone with me." We walked on the beach while the children flew their kites. So it went. Two weeks of not calling the Wall Street firm where I am a director; a visit to the shell museum though I usually hate museums. Relaxed and happy, that's how the whole vacation passed. I made a new promise to keep on remembering to choose love. There was one thing that went wrong with my experiment, however. Evelyn and I still laugh about it today. On the last night at our cottage, preparing for bed, Evelyn stared at me with the saddest expression. "What's the matter?" I asked her. "Tom," she said in a voice filled with distress, "I don't?" "What do you mean?" "Well...that checkup I had several weeks ago...our doctor...did he tell you something about me? Tom, you've been so good to me...am I dying?" It took a moment for it all to be understood. Then I burst out laughing. "No, honey," I said, wrapping her in my arms. "You're not dying; I'm just starting to live."
Answer: with his children
[A]: From the story we may infer that Tom drove to the beach cottage _ .

[Q]: Article: Human beings have spread to every continent, sometimes driving other animal species to extinction in the process.It has become the most widely spread species on the planet, occupying mountains and valleys, deserts and jungles, shorelines and islands, yet always finding some good means of living in these widely differing environments. The total weight of all living members of the species is far heavier than that of any other animal, and the human population is now growing so rapidly that it will double within the next thirty-five years. What accounts for the success of our species? The answer, in a word, is culture. We create culture, but culture in turn creates us.We are consequently no longer the victims of the environment.We make our own social environment, inventing and sharing the rules and patterns of behaviour that shape our lives and we use our learned knowledge to make the natural environment more suitable to live in. Our shared culture is what makes social life possible. Without a culture transmitted from the past, each new generation would have to solve the most basic problems of human existence over again. It would have to think up a family system, to invent a language, to discover fire , to create the wheel, and so on. Culture frees us from relying on the slow and accidental process of physical evolution by offering us a new, purposive , efficient means of adapting to changing conditions. If we waited for natural selection to enable us to live at the North Pole, to fly to the moon, or to live under the sea , we would wait forever. Unlike other animals, we can self-consciously adapt to our environments and can adapt environments to meet our own needs.
