Based on historical documents, modern survey and statistics, as well as the result of predecessor studies, the trend and main process of forest dynamics are recognized.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

American eating is funny. They eat almost everything with a fork, and it appears that holding a knife in ones right hand longer than a few seconds is considered to be against good table manners.

The system is that if it is absolutely necessary to use a knife, people take the fork in their left hand, and cut off a piece of meat or whatever it is in the normal manner. Then they put the knife down, transfer the fork to their right hand, and only then do they transport the food to their mouth. This is clearly ludicrous(滑稽可笑), but it is considered good manners.

There are several results of this system. First, if it is not absolutely necessary to use a knife, Americans dont use one, because obviously this greatly complicates(使复杂化) things, and you will therefore see them trying to cut things like potatoes, fish and even bacon(熏猪肉) with a fork. Second, towards the end of a course, since only one implement(器具) is being used, food has to bo chased around the plate with the fork - and for the last mouthful the thumb has to be used to keep the food in place, although one is not supposed to do this.

Third, tables are generally laid with one knife and two forks, the outside fork being for the salad. There is no need for foreign visitors to follow the American system and try to eat the salad with only a fork, but if you do use your knife, remerber to save it for the meat course. Even desserts(甜食) (except ice cream) are eaten with a fork if at all possible, and the spoon you see by your dessert is meant to be for coffee (but if you use it for your dessert no one will say anything).

I am a third year master major in automation at Shanghai Jiao Tong

University, P. R. China. With tremendous interest in Industrial Engineering, I

am writing to apply for acceptance into your Ph.D. graduate program.

Education background

In 1995, I entered the Nanjing University of Science & Technology

(NUST) -- widely considered one of the China’s best engineering schools. During

the following undergraduate study, my academic records kept distinguished among

the whole department. I was granted First Class Prize every semester,In 1999, I

got the privilege to enter the graduate program waived of the admission

test.

At the period of my graduate study, my overall GPA(3.77/4.0) ranked top 5%

in the department. In the second semester, I became teacher assistant that is

given to talented and matured students only. This year, I won the Acer

Scholarship as the one and only candidate in my department, which is the

ultimate accolade for distinguished students endowed by my university.

Presently, I am preparing my graduation thesis and trying for the honor of

Excellent Graduation Thesis.

Research experience and academic activity

When a sophomore, I joined the Association of AI Enthusiast and began to

narrow down my interest for my future research. With the tool of OpenGL and

Matlab, I designed a simulation program for transportation scheduling system. It

is now widely used by different research groups in NUST. I assumed and fulfilled

a sewage analysis & dispose project for Nanjing sewage treatment plant. This

was my first practice to convert a laboratory idea to a commercial product.

In retrospect, I find myself standing on a solid basis in both theory and

experience, which has prepared me for the Ph.D. program. My future research

interests include: Network Scheduling Problem, Heuristic Algorithm research

(especially in GA and Neural network), Supply chain network research, Hybrid

system performance analysis with Petri nets and Data Mining.

大熊猫可是中国的国宝，非常可爱。

它有一身黑白相间的皮毛，圆圆的脸上有两个黑眼圈和一双小眼睛。头上有两个黑黑的，圆圆的小耳朵。

熊猫一般居住在丛林深处的山谷地带，它们会挑最鲜嫩的竹子吃，有时还会用又大又宽的爪子剥竹笋吃。除了竹子和竹笋以外，有时它们还会吃一些其他的植物，偶尔也吃一些肉。它们喜欢爬到树上休息，也喜欢在从林间奔跑、玩耍、打闹。有的时候，它们还会凑到一起“打一架”呢！

熊猫之所以稀少，是因为野生的大熊猫繁殖能力很差。而且熊猫妈妈生下两个宝宝的话，只有能力喂养其中一个，那另一个就会活活饿死。这真是十分令人悲伤的事情。所以现在的大熊猫，很多都是靠人工喂养出来的。

熊猫也是和平天使。在中国与其他国家或地区的交往中，有时会把熊猫作为国礼赠送给世界各地的人民，这样，当地的居民也能看到来自中国的可爱的大熊猫。是它们搭建起了中国和世界各地的友谊桥，这样美好的动物，怎能让人不喜爱呢？

熊猫是世界上最珍贵的动物之一。熊猫的家主要在四川、甘肃、陕西省的各个山岭里，数量十分稀少，属于国家一级保护动物之一，被人们称为“国宝”。下面是小编整理的描写熊猫的英语作文，欢迎查看。 写熊猫的英语作文一
