"Uncle Sam", of course, stands for the United States, which is the nickname of the country.It is hard to believe that this nickname came out quite by accident and there actually was a man called "Uncle Sam". However, few people have ever heard of such a man. The man called "Uncle Sam Willson" lived in New York and ran a meat-packing business. One day, a mayor (市长) came to his shop and noticed the EAUS in front of the houseand asked what they stood for. And a workmate added jokingly that "US" stood for "Uncle Sam Willson". In May 1813, this story appeared in a newspaper published in New York. Since "Uncle Sam" was a popular man and was an example of hard-working and patriotic (爱国的) American,the idea of Uncle Sam as a name for this kind of men caught on (流行) rapidly. By the end of the war of 1812, "Uncle Sam" had come to symbolize(象征) the character of the nation and the government and the nickname of the U.S.

When scientists scan the global horizon, over?fishing, loss of species habitat, water shortage, climate change, and invasive species seem to be the biggest threats to the earth. Then what will our world be like in 2050?
There are two features in the growth of world population. First, the United Nations estimates that by 2050, the population of European countries will decrease from the current 0.72 billion to 0.63 billion. Second, the population in developing countries is growing rapidly. By 2050, the population of Africa is expected to reach 1.8 billion, 0.9 billion more than its present population.
Global warming will become more and more serious. A recent research report published by the United Nations indicates that it's quite possible that the Earth's temperature is rising well above the previous estimate. Such an outcome would have severe consequences. For example, a research team from the University of Colorado used satellite data to estimate that the ice sheet will lose up to 48 cubic (立方的) miles by 2050. Ice shelves in the Antarctic will have decreased by more than 7,200 square miles in the next forty years.
There will be more severe water shortage. Africa's rivers face dramatic change that will leave a quarter of the continent severely short of water by the middle of the century, according to a global warming study. Even modest decreases in rain in western Africa will see rivers lose as much as 80% of their water.
Today there are 620 million private cars worldwide. With current growth trends, that number is expected to reach three billion worldwide by 2050. If we continue to burn fossil fuels at current rates, levels of carbon dioxide in the atmosphere will reach 550 ppm (parts per million)—double pre?industrial levels—by around 2050. This will increase global temperatures by between 1.4℃ and 4.8℃ by 2050, and sea levels will rise by between 0.09 meters and 0.78 meters.
