  Based on historical documents, modern survey and statistics, as well as the result of predecessor studies, the trend and main process of forest dynamics are recognized. The forest area and forest coverage rates for each province of China from 1700 to 1949 are es- timated backward by every 50 years. Linking the result with modern National Forest Inventory data, the spatial-temporal dynamics of Chinese forest in recent 300 years (AD 1700–1998) is quantitatively analyzed. The study shows that in recent 300 years, the forest area in current territory of China has declined by 0.95×108 hm2 (or 9.2% of the coverage rate) in total, with a trend of decrease and recovery. Before the 1960s, there was a trend of accelerated de- scending. The forest area was reduced by 1.66×108 hm2 (or 17% of the coverage rate) in 260 years. While after the 1960s, there has been a rapid increase. The forest area increased by 0.7×108 hm2 (or 8% of the coverage rate) in 40 years. The study also shows that there is a significant spatial difference in the dynamics of forest. The amplitudes of increasing and de- creasing in western China are both smaller than the ones in eastern China. During the rapid declining period from 1700 to 1949, the most serious decrease appeared in the Northeast, the Southwest and the Southeast, where the coverage rate in most provinces dropped over 20%. In Heilongjiang Province, the coverage rate dropped by 50%. In Jilin Province, it dropped by 36%. In Sichuan Province and Chongqing Municipality, it dropped by 42%. In Yunnan Prov- ince, it dropped by 35%. During the recovery period 1949–1998, the western provinces, mu- nicipality and autonomous regions, including Ningxia, Gansu, Inner Mongolia, Si- chuan–Chongqing, Yunnan, Tibet, Xinjiang and Qinghai, etc, the increase rates are all below 5%, while the eastern provinces, municipality and autonomous regions (except Heilongjiang, Hubei, Jiangsu–Shanghai) have achieved an increase over 5%, among which the Guang- dong–Hainan, Guangxi, Anhui, Beijing–Tianjin–Hebei, Shandong, Henan, Zhejiang, and Fu- jian have an increase over 10%.

  June 6th Thursday Sunny

  This afternoon a young American friend called Mike came to our school. He visited our lab, library and school factory. At five o'clock he had a free talk with some of my classmates. I was lucky to be one of them.

  Mike spoke English slowly and carefully, so we could understand what he said. We talked about our English study for about an hour. Before he left our school, I asked him in English, "What do you think of our school?" He answered with a smile, "Oh, it's wonderful!"

  This is the first time for me to talk with a foreigner in English. English is really userful.

  What Is American Dream?


  What is the American Dream? Is it the same for all Americans? Is it a myth? Is it simply a search for a better life? How has the American Dream changed over time? Some see their dreams wither and die while others see their dreams fulfilled. Why? Everyone has dreams abut a personally fulfilled life... and what is your dream?


  The term American Dream was first used by James Adams in his book The Epic of America which was written in 1931. He states: The American Dream is that dream of a land in which life should be better and richer and fuller for everyone, with opportunity for each according to ability or achievement. It is a difficult dream for the European upper classes to interpret adequately, and too many of us ourselves have grown tired and mistrustful of it. It is not a dream of cars and high wages merely, but a dream of social order in which each man and each woman shall be able to get to the fullest stature of which they are capable, and be recognized by others for what they are, regardless of the fortuitous circumstances of birth or position."


  In the united States' Declaration of Independence, our founding fathers state: "... all Men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the Pursuit of Happiness." Might this view be considered the foundation of the American Dream?


  Were homesteaders who left the big cities of the east to find happiness and their piece of land in the unknown wilderness of the west pursuing these Rights? Were the immigrants who came to the United States looking for their bit of life, liberty, happiness and their Dream? And what did the desire of the veteran of World War II—to settle down, to have a home, a car and a family—tell us about this Dream? Is the American Dream attainable by all Americans? Would Martin Luther King feel his Dream was attained? Did Malcolm X realize his Dream?
