Based on historical documents, modern survey and statistics, as well as the result of predecessor studies, the trend and main process of forest dynamics are recognized.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

The main content of American culture is the emphasize on individuals' value,the pursue of democracy and freedom,the promotion of deploitation(开拓,经营) and competition and the need of realistic and practicality.Its core is individualism:self first,personal need first,pursue of individual benefit and enjoyment,emphasize on achieving individual value by self-strive and self-design.This type of intentionally build up of personality and pursue customized individualism has its pros and cons,it gives incentives to people and make them exert on their potential and wisdom and as a result accelerate the development of the entire race and nation; on the other hand it is difficult to keep good relationship among people if everyone is egocentric thus make the entire society lack of unity.
American citizens emphasize on achievements and respect heroes.They have great sense in their hearts to praise success and heroes.Personal achievements are one of those with the highest value in Americans mind.Americans have very strong senses of success.Success is the pursuit of most Americans,it is their attractive future and the incentives for moving forward.They believe that one's personal value is equivalent to his achievements in his career.Some high achievers in their career such as entrepreneurs,scientists,artists and all kinds of super starts became modern heroes.The process and result of how they strived have become the frame of reference of social culture value and the real life text book for parents to educate their children.
American society has great movements within itself.These movements are shown in two aspects:movements amongst locations and movements inside the society.The United States are relatively more open and have more freedom.Developed transport and the tradition of adventure and sporty makes a lot of American migrate from countryside to cities,from downtown to uptown; and from north to the southern sunny land,from one city to another.Unlike European countries,the social classes in America is not so stable.Further more,with the advocation of public education,movements upwards along the social ladder have become possible.Many people living in the states,no matter whether they are Native American or immigrants from overseas,have the same dream of changing their social class and make their lifetime dream come true through their own efforts.This is what they often called "American dream".
美国英语作文 篇3
the ways of history are so intricate and the motivations of human actions so complex that it is always hazardous to attempt to represent events covering a number of years, a multiplicity of persons, and distant localities as the expression of one intellectual or social movement; yet the historical process which culminated in the ascent of thomas jefferson to the presidency can be regarded as the outstanding example not only of the birth of a new way of life but of nationalism as a new way of life.
the american revolution represents the link between the seventeenth century, in which modern england became conscious of itself, and the awakening of modern europe at the end of the eighteenth century. it may seem strange that the march of history should have had to cross the atlantic ocean, but only in the north american colonies could a struggle for civic liberty lead also to the foundation of a new nation.
here, in the popular rising against a "tyrannical" government, the fruits were more than the securing of a freer constitution. they included the growth of a nation born in liberty by the will of the people, not from the roots of common descent, a geographic entity, or the ambitions of king or dynasty.
with the american nation, for the first time, a nation was born, not in the dim past of history but before the eyes of the whole world.

Going abroad for Studies
The other day I announced that I would go abroad for further studies right after my college education. My decision evoked the immediate objection of my family： Why? Why should I borrow a huge sum of money for overseas studies while I might receive the same education at home at relatively low cost? My answer is： in addition to knowledge， I can gain experience that those who stay at home will never have.
First， experience is the opportunity for the real-life use of foreign languages. While a person can study a foreign language at home， the effect can never be compared with constant use of the language in academic and everyday life. There is no better opportunity to improve second-language skills than living in the country in which it is spoken. Living in English-speaking countries such as America and Australia for several years， for example， my English will be as perfect as native speakers.
Second， living and studying abroad offers me a different perspective of the world. On a university campus， foreign students are likely to encounter their counterparts from different countries and areas and are exposed to different ideas and values. This helps me to have a meaningful understanding of different societies and inevitably sees my own country in a new light.
Third， overseas experience， frustrating and painful as it may be， is helpful. A person going abroad for study often experiences much more difficulty——difficulty in adapting to a new culture and in dealing with all problems alone. Yet， the difficulty， coupled with the frustration brought on by culture shock， is a rewarding experience for one's future life and development of personality.
Although going abroad is expensive and perhaps painful， the payoff is worthwhile. For the benefit is not merely knowledge gained， but the experience desirable in one's personal life.

Today we set foot in a fascinating place - Barnard primary school in the holy land of Argo.
As soon as I got off the bus, a gentle breeze swept through the primary school, which was full of flowers and trees. Although it was winter, I felt that the four seasons were like spring. Then a man in a suit came over. He was very kind, and he was the principal of the elementary school. He waved kindly to us, and he led us into the learning paradise. As I entered the classroom, a joyful song echoed around my ears, and the dancing of passion was accompanied by a flexible body, which was very impressive! Then we walked into the school's long corridor, although it was in the United States, and did not celebrate the Spring Festival customs, but in the long corridor, the classroom still lights up the lanterns, welcomed the new spring. There, we met many new friends, and we met one-on-one, and the joy of our hearts was like a torrent of water.
Time at the moment our always stop, and at the moment our slip away, we must have to leave the intoxicating campus, I love love will not give up to looking at the campus behind him, want to have this wonderful memories forever treasure.
