Article: On Jan 23, 2012, I was aboard a ship on the Yangtze River, listening to the sound of fireworks and eating plate after plate of dumplings. On Sunday Feb 10, 2013, I was preparing to celebrate Chinese New Year again - in London's Chinatown. It was raining. It was cold. But ever since I left Beijing in August, I had promised myself I would celebrate Chinese New Year - if only to help with my Beijing "homesickness". Central London was dressed up for the occasion. There was a stage for a big fireworks display for the evening. Even so, it wasn't like my real Beijing chunjie. Even buying a baozi didn't cheer me up. It cost about 10 times as much as the real thing does in Beijing and got stuck to its rain-ruined paper bag. Cold, wet and depressed, I ran into a shop for shelter. Suddenly, there it was. Between the packets of dried meat and fish, the bags of rice and the smell of dried noodles in this little Chinese supermarket, I had found home. An hour later, I hurried into my house with bags of frozen jiaozi, packets of sauce and a large bottle of vinegar. I boiled water, tore open the packets, grabbed my chopsticks and settled down to a feast. This, I thought, is a Happy Chinese New Year. I even watched the fireworks on TV. After all, why face the British weather when I can bring China home in one bite?
Answer: very depressed

Article: A rising population is one of the main reasons that there is global warming. Between 1650 and 1850 the population increased by 0.75 billion people going from 0.25 billion to one billion. From 1930 to the end of the century the population rose from two billion to over six billion. In just a third of the time the population rose by more than five times what it did before. It is expected that this trend in the changing population will continue and could even heighten. The growing population requires increasing amounts of energy. These energy demands and other supplies require production, which almost always involves the emission of greenhouse gases. The more the population increases the more greenhouse gases that are produced and the greater the increase in temperature. The burning of fossil fuels is one of the best-known causes for global warming. The major reason for fossil fuels contributing so much to global warming is the release of carbon that occurs during the burning of fossil fuels. When people burn fossil fuels, they release large amounts of carbon by way of the release of carbon dioxide. The carbon dioxide in the air then leads to global warming. Another source of carbon dioxide comes from _ . In forests there is a large amount of carbon that is stored in the trees and other plants. This carbon is out of the atmosphere because the trees consume the carbon from carbon dioxide. When people cut down trees, they are frequently burned. This burning releases the carbon dioxide into the atmosphere that was stored in organic matter. Even when new trees are planted, it can take up to one hundred years to make up for the carbon that was released. It is commonly thought that because trees absorb more carbon dioxide, the atmosphere experiences positive effects. Sophie Armstrong, the writer of Earth Care put it, "There's no doubt that the earth is becoming warmer because of human activity rather than a random but natural phenomenon.
Answer: Carbon Dioxide

Article: China news, Beijing, Feb. 9 - Housing price in China has always aroused heated discussions among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles in Chinese real estate market, the International Finance News reported. Although the average price of residential houses in the United States, after converted to Renminbi, is about 8,000 yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold at a price even higher than those in the US. The high housing sales price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people's average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US? At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered.
