    A recent study finds that the dirt on the ground is likely to worsen climate change. Researchers have shown that warmer temperatures are heating the soil, which is causing microbes (微生物) to become more active and release more of the soil's carbon into the atmosphere. These soil changes can potentially contribute to even higher temperatures.

    Scientists studied device readings, soil measurements, plant growth details and satellite observations from around the world. Their work is the most complete study on the subject.

    They found a sharp increase in carbon released into the atmosphere by bacteria and fungi (真菌) in soil from 1990 to 2014. Researchers explain that the carbon comes from the dead plants and leaves the microbes eat. As temperatures rise, the microbes eat more. And the more they eat, the more carbon can be made into carbon dioxide and released into the atmosphere.

    This uncontrolled cycle speeds up and intensifies climate change. Overall, soil releases about nine times more carbon than human activities. But that is part of a natural cycle: the amount of carbon released into the air is about equal to the carbon oceans and plants take in.

    However, carbon released from fossil fuel causes an imbalance. Burning coal, oil and natural gas puts more carbon into the atmosphere than nature can take in. The additional carbon heats the air and soil. And as the air and soil get hotter, the earth will release more carbon than it has been holding.

    If something isn't done, we are really in trouble. Proper soil conservation can help keep more carbon in soil. Conservation methods include avoiding turning the soil, covering off-season crops and leaving crop deposits on the ground.

    Developed and developing nations can learn from each other seeking a low carbon economy, a Chinese government official said in Shanghai yesterday. “China doesn't lag developed nations in terms of energy saving and green economy”, said Zhou Changyi, director of the energy saving department of the Ministry of Industry and Information Technology.

    “While we can learn many aspects from developed nations, they also should learn something from us, such as water conservation,” Zhou said in a speech during the new Path of China's Industrialization forum at the ongoing China International Industry Fair 2009.

    He said industrialized nations and China are dealing with different issues to combat climate change. The United Kingdom, for example, is concerned about transport, buildings and new energy in reducing carbon emissions. For China, the most urgent task is how to realize new type of industrialization and avoid mistakes that other countries made when they industrialized.

    As such, overseas exhibitors at this year's fair are showing ways to help China achieve low carbon emissions in the industrial section.

    Swiss power and automation technology group ABB called for a stronger focus on product lifecycle assessment, or LCA, which is used to study the environmental impact of a product from the research and manufacturing stage through its usage and recycling.

    Tobias Becker, head of ABB's process automation division for North Asia and China, said LCA is an effective tool in helping manufacturing industries to reduce carbon emissions.

    LCA shows that industrial customers should focus on a product's environmental impact throughout its lifecycle instead of on its initial investment or ready to use stage. For example, a motor's initial investment accounts for only 3 percent of its lifecycle cost, while 94 percent goes to fuel consumption and the rest to maintenance.

    Richard Hausmann, North East Asia CEO of Siemens, said, “The color of future industrialization is green.”

    The Germany Company recently announces that it wants to receive orders worth more than 6 billion Euros (US 8.8 billion) for intelligent net power networks, Smart Grid, over the next five years. Siemens has set a 20 percent market share target for the global smart grid business.

    A smart grid delivers electricity from suppliers to consumers using digital technology, advanced sensors specialized computers that save energy, reduce costs and increase reliability. The United States and China are considered the two biggest markets for smart grid.

    Until recently, scientists had mapped only about 20 percent of the sea floor. But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers (海洋学家), industry and governments.

    The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean.

    The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency's Cryo-2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar (声波定位仪) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.

    The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor.

    David Sandwell says the map is a powerful tool for fisheries, those interested in protecting the environment and for oil exploration.

    “The petrol exploration industry is interested in how to reconnect the continents, bring them back together tectonically so you can map the basins (盆地)on one continental edge—say, Africa—and use that to establish where the similar basin would be on the other continental edge in South America.”

    If scientists know that information, they may be able to find oil fields. The new data also will help scientists improve their estimates of ocean depths. This information can help ships travel safely and improve military operations and scientific projects worldwide.

    Mr. Sandwell thinks scientists will make many more discoveries as they examine the new map and the information it provides.

Choose the one that fits best according to the information given in the passage you have just read.

    After some blood tests, Dr Stubs stood before me, a tall man, but short on personality and sporting a cold expression. You have systemic lupus, he said matter-of-factly. "Lupus," he continued, "is an auto-immune disease and …." I remember certain details but mostly I remember him talking about children. "Children are no harm. But childbirth would jumpstart additional symptoms that could be life threatening. You already have two kids anyway."

    As I got up to leave, shaken and drained, he said his parting words, "I would discourage any further research. There is no cure and nothing can prevent its progression."

    Still, I did research lupus and its symptoms tiredness and joint pain-were both consistent with what I was experiencing. And eventually some major organs could be affected, causing shutdown and possibly death.

    I studied and found out that echinacea had a record in making immune system stronger. I decided that along with the plant I would strengthen my mindset by immersing myself in my family with my one-year-old son and three-year-old daughter.

    After another visit, I decided never to go back to Dr. Stubs. How could one endure repeatedly hear desperately words coming from an emotionless mouth even though they were truth? The years passed. When I would feel tired and achy I pulled support from my children and their laughter.

    Finally, after eight years, I went to Dr. Kirstein who was recommended by a friend. She stood there holding my hand and looking into my eyes warmly.

    "So let's talk a little

    Instantly my defenses were down. Before I knew it, she had me running on and on about my children, my husband, my life and dreams. I told her about all the meaningful activities I was involved in, those things I might have never done without the disease.

    After several follow-up tests, and greater research into my family history, Dr. Kirsteincame to conclusive answer. I did not have systemic lupus. There must be something wrong with the initial tests 8 years before.

    I didn't know whether I should jump for joy or scream because I had been living the last eight years in fear of a fatal disease. But then I realized that I had been living every day, not so much in fear, but happiness Even day was a gift and I knew it.

    In the book The Best Little Girl in the World, Kessa has a serious eating disorder (进食障碍) called anorexia nervosa. But she is not alone. Many people have this eating disorder.

    In the beginning of her story, Kessa is a normal 15-year-old girl. She is good at many things, especially dancing. She has danced for many years and loves it. One day her dance teacher tells her to continue eating right, but maybe lose a few pounds. Once Kessa hears this, she takes things too far. Instead of cutting down on snacks and junk food, she decides not to eat at all. She does not eat breakfast, lunch, or dinner. She begins losing weight and becomes slimmer (更加苗条的) and slimmer. But she loses weight to a point where she is unhealthy.

    As her poor eating habits continue, her parents start getting as much help as possible to cure (治疗) their beautiful daughter. But it is just as hard for Kessa's parents to deal with her disorder as it is for her.

    Every day she exercises to lose more pounds and plans what and when she will eat. Her parents try everything, but Kessa decides not to have any fat on her body.

    Kessa's doctor and parents finally take her to the hospital. She is now so thin that she can hardly walk. There, she is given good care.

    In the rest of the book, Kessa goes through a lot of trouble in order to cure her eating disorder. This book, I think, can help to prevent people from doing this to themselves. It shows the trouble that people go through just to be slimmer, and all the terrible things they must experience to be cured. It is a book I think every teenager should read.

    The Great Depression that followed the stock market crash of 1929 saw hundreds of thousands of Americans out of work. In the years of great fear and depression, a lot of American citizens looked desperately to the federal government for assistance. Of all the programs designed by President Roosevelt when he took office in 1932, few were more criticized - or had more lasting impact - than the Work Projects Administration, better known as the WPA.

    The intention of the WPA, which functioned from 1935 to 1943, was to design and administer public works projects to help relieve unemployment. The majority of these projects involved historic or artistic attempts. The WPA's Writers Project, for example, was responsible not only for such practical works as state guidebooks but also for the collection of historically valuable oral histories. Over 2,900 of these records were collected in 24 states. They provide an irreplaceable firsthand account of people's diets, customs, celebrations, and political and religious beliefs at the time.

    The artworks created through the Federal Arts Project are one of the WPA's most lasting achievements. Out - of - work painters, both famous and unknown, created paintings that beautified schools, libraries, and government buildings, WPA photographers traveled across the country recording the hardships of life on small rural farms. When the United States entered World War Ⅱ in 1941, WPA artists were enlisted to produce posters supporting the war effort. Many WPA artworks, including hundreds of small drawings picturing scenes of everyday life, still exist today.
