　　Americans sometimes fall into the trap of thinking that American values are universal ones. We cant always see that our values are actually typical American values. Instead, we assume the things Americans value are obviously what everyone should believe in.

　　But we should remember the saying: when you "assume," you make an "ass" out of "u" and "me." We only need to look at what happens when Americans go as advisors to developing countries to see how wrong our assumptions can be. Some Americans go thinking theyre sharing pearls of wisdom with the backward natives about how to get things done right. They assume that stimulating competition and giving financial incentives for individual achievement will naturally change peoples behavior and lead to success. When their projects barely get off the ground, they cant understand what went wrong. They mistakenly think that people must just be lazy or that they dont really want a higher standard of living.

　　So the advisors wind up getting discouraged and going home, grateful to be surrounded by hardworking Americans again.

　　In these situations, we should realize that American values may come from Americas unique position as the land of opportunity. We are brought up with the American dream that everyone can work hard and get ahead. But we should realize that in countries with a different history and different opportunities, other values might be more important, like avoiding conflict or saving face.

　　The present-day continental United States has been inhabited for at least 15,000 years by indigenous tribes. After European exploration and settlement in the 16th century, the English established their own colonies-and gained control of others that had been begun by other European nations-in the eastern portion of the continent in the 17th and early 18th centuries. On 4 July 1776, at war with Britain over fair governance, thirteen of these colonies declared their independence. In 1783, the war ended in British acceptance of the new nation. Since then, the country has more than quadrupled in size: it now consists of 50 states and one federal district; it also has numerous overseas territories.

　　Based on historical documents, modern survey and statistics, as well as the result of predecessor studies, the trend and main process of forest dynamics are recognized.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%.

　　Social customs differ in different parts of the world If we don"t realize this,misunderstanding may arise between people that behave differently In the United States,people are very informal in social situations For example,they call each other by their given names when two people first meet So do the young to the old In,it would be regarded quite impolite to do so.

　　Another difference is about what can be talked about in a conversation A Chinese thinks nothing of being asked how much his coat cost while Americans think it impolite to ask such a question A Chinese woman doesn"t care if she is asked about her age Politics,religions,as well as ines are often talked about among Chinese But in the United States these kinds of subjects are usually avoided in conversation.

　　Since there are many other different social customs between Americans and Chinese,the way that we behave and what we talk about requires our attention If we keep these in mind,we will do it better and understand each other better.
