美国英语作文 篇1
Based on historical documents, modern survey and statistics, as well as the result of predecessor studies, the trend and main process of forest dynamics are recognized.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%.

美国英语作文 篇2
the united states covers a large part of the north american continent。 its neighbours are canada to the north, and mexico to the south。
when this land first became a nation, after winning its independence from engand, it had thirteen states。 each of the states was represented of the american flag by a star。 all these states were in the eastern part of the continent。 as the nation grew toward the west, new states were added and new states appeared on the flag。 for a long time, there were 48 states。 in 1959, however, two more stars were added to the flag, representing the new states of alaska and hawaii。
indians were the first inhabitants of the land which is now the united states。 there are still many thousands of the descendants of these original inhabitants living in all parts of the country。 sometimes it is said that the indians are "the only real americans。"
most americans, however, are descendants of people who came from all over the world to find a new life in a new land。 those who came first and in greatest numbers to make their homes on the eastern coast of north america were mostly from england。 it is for that reason that the language of the united states is english and that its culture and customs are more like those of england than of any other country in the world。
美国占去北美大陆很大一部分土地。它北邻加拿大,南接墨西哥。
这片土地刚从英国独立出来,成为一个国家的时候,只有十三个州,每个州在美国国旗上由一颗星来代表。这些州都在东部。当这个国家不断向西扩大,就增加了新的州,同时它们也出现在国旗上。很长一段时间,美国有48个州,可是,到1959年,国旗上又多了两颗星,分别代表阿拉斯加和夏威夷。
印地安人是如今叫做美国的这块土地上的最初居民。现在在全国各地仍然居住着许多这些原始居民的后裔。有时人们说印安人才是“真正的美国人”。
不过,大部分美国人是来自世界各地要在这个新世界里对找新生活的人的后代。那些最早大批来到北美东海岸建立家园的人大部来自英格兰,也是由于这个原因,美国的.国语为英语,而它的文化习俗也与英国的更为相像。
美国英语作文 篇3
Cars are an important part of life in the United States. Cars have made the United Slates a nation on wheels.
There are 3 main reasons why the car has become so popular in this country. First of all, Americans like to travel. The car provides the most comfortable and cheapest form of transportation. With a car people can go any place without spending a lot of moncy.
The second reason that cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation. Long-distance trains have never been as common in the United States as they are in other parts of the world. Air-service provides a comfortable travel system. But it is too expensive to be used frequently.
The third reason is the most important one, though. The American spirit of inde pendence is what really made cars popular. Americans do not like to wait for a bus, or a train or even a plane. They do not like to have to follow an exact schedule. A car gives them the frecdom to schedule their own time, and this is the freedom that Americans want most to have.
小汽车是美国最重要的交通工具
在美国小汽车是生活的重要组成部分。小汽车使美国成为轮子上的国家。
小汽车在美国如此流行有三个原因:首先,美国人喜欢旅游,小汽车是最舒适和最便宜的交通工具,有了汽车,人们不需花许多钱就能到处旅游。
第二个原因是,在美国有效的、便宜的公共交通从来就没有真正发展起来。长途火车在美国从来不像世界其它国家那么普遍,空中运输提供了舒适的旅游系统,但是由于机票太贵以致不能常坐。
第三个原因是最重要的。美国人的独立精神是小汽车流行的真正原因。美国人不愿意等公共汽车、火车、甚至不愿等飞机。他们不想按照时刻表办事。小汽车让他们自由地安排自己的时间,这是美国人最喜爱的自由。

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5
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.
美国英语作文 篇6
The topic like“what’s a university?” or “what a university should do?” has been discussed many times in every age. Not only educationalists but also students take into it. Is it necessary to give priority to skills and knowledge in university education as they are essential to employers? Or students in universities should have access to all of knowledge just as they have their own sake? Chose A or B, this is a problem.
The value of knowledge itself need to be considered first in university education even though the course is not as practical as skills and technology. In Chinese culture, morality education is always took at first. It said that the way of real learning is to develop and expand virtue, to innovate peoples’ opinions, to get the best goodness. In addition, there are four stages in the success of a gentleman: first, to cultivate his moral characters; second, regulate his own family; third, rule the state successfully; forth, let the world get peace. In Chinese traditional value, students in
university need to develop his morality firstly, though these knowledge is not as useful as other skills after they get a job.
On the other hand, the practicability of a university course is also worth considering, especially in the age when our government call for the attention to skills and technology in university education and when the employees prefer to capacity and practical knowledge of employers. The time in university is limited and conditions and aims of students are different. When students chose which course to learn, it is inevitable for some of them prefer to those which are more needed in workplace.
Universities give equal access to all of knowledge, including the practical courses and others. What’s more, they need give more chance to students to choose what to learn. Congratulate on diversity!
