Despite the cultural conflicts between the Orient and the Occident, there do exist some admirable ingredients in the Western culture.

First and foremost, the equality between parents and children. The parents are not always superior to their children, and the children do not always need to obey their parents ‘order, that is, they are more like close friends.

Second, the independent personality. Western people have a strong sense of supporting themselves and being independent. They begin earning their pocket money early in their life, even as kids.

Last, Western people do not always assess a person according to his background. If only he can achieve success through personal struggle, he can win status. Its a talent-oriented society, not background-oriented.

星期五，是我们四年级和三年级的英语节表演。

早上八点，同学们都准时来到了流花校区的科技大楼广场，我见到所有的同学都穿得漂漂亮亮，而且都化了妆，好漂亮啊！大家排好队，老师就带我们上楼了。 到我们班表演了，我们班唱的是《冰雪奇缘》主题曲。我们排着整齐的队伍走上了舞台，同学们用响亮 的声音唱着动听歌曲。我们表演完以后，在台下家长们的掌声中慢慢地退下了舞台。

之后，我们就来到了后台坐在那儿看书，见别人班的表演，我觉得很可惜。

回到家我听妈妈说才知道，这次表演最好的是：九班和十班还有一班和二班。我想这次不是最好的没关系，正所谓“尺有所短，寸有所长”，每个人都有自己的别人的优点。我也为得奖同学感到骄傲！听说所有英语老师还一起表演了 法语歌曲，我一直觉得他们只会唱英语歌，今天见到老也暗自下决心一定要学好英语。期待下次的英语节我们班也能得 希望下次我们能亲眼看别人班的表演。 这次的英语节真的非常有意义！

Good afternoon,honorable judges. I am glade to be here for this interview. First let me introduce myself to you. My name is **, 23. I come from zhengzhou, the capital of Henan Province. I will graduate from the Central South University in july this year.

After four years’ extensive training in science and engineering with a focus on microbiology and biotechnology in the last one and a half years, I am fully absorbed in biology and their various novel applications. Driven by my interest and capacity in these areas, I would expect myself to be a senior professional in 10-15 years time, working as either a faculty member in a university or a researcher in some institute.

Having realized that such a goal would require much more knowledge than what I have acquired, I am determined to pursue graduate study in a best university. The origination of my interest dates back to my senior high school year when I attended an intensive but interesting course given by the biological teacher on general biology. My interest was reinforced when I had the opportunity to participate in some research projects in the Central South University. In May, 2003, I began working with prof.Zhou to do research on microbial treatment processes for the nitrogen removal in wastewater. I participated in the separation method of nitrifier and denitrifier (chemolithoautotrophic bacteria, very small colony, grows slow, have the same color with the culture medium) and do some research on their Physiology characteristics.

I have been consciously strengthening my research ability by teaching myself advanced knowledge including microbial physiology, microbial statistics. Through these projects, I have not only learned many practical techniques but also acquired a solid theoretical background and a broad scope in scientific research in my fields of interest. Despite the intensive curriculum, I have always kept an eye on a broader world outside.

As a member of the CSU-Students Union, I’ve improved my communication and cooperation skills through some meaningful activities. It has become clear to me that a good academic environment can play a very important role in my pursuit of excellence. I believe pursuing a Master’s degree at CSU, would be a most reasonable extension of my academic pursuit and a major step forward toward my career goal.

I love many animals. I love dog, cat, hamster, pig and elephant.

My favorite animal is a little rabbit. It is my pet, its name is Lily. Lily has a pair of long ears, its body is white, and its eyes are red.

It likes to eat carrot. It is very lovely, I like to play with it.

Halloween is for the "All Hallows Evening"。 However， due to various reasons， Halloween has become the years most popular and one of the most popular festivals， and many players with great enthusiasm to celebrate this holiday。

Halloween in the October 31， in fact， praise and autumn festivals like Beltane is the festival of spring like the praise。 Of ancient Gaul， Britain and Ireland priest - druid to have a grand festival praise of autumn， from October 31 beginning at midnight the following day， November 1 continued all day。 In their view， that night they are a great Death - Salman to that year were all summoned the ghost of dead people， these evil spirits are subject to care for the Livestock Health and punishment。 Of course， as long as the thought of such a gathering of ghosts， it was enough to make fools of those simple-minded understanding of the heart bile war。 So they lit the sky of the bonfire， and close surveillance of these evil spirits。

Halloween witches and ghosts everywhere to say is just the beginning。 So far in Europe， there are some isolated areas where people believe it is true。 Ancient Rome in November 1 there is also a holiday， which is used to pay tribute to their goddess of Bo Mona。 They bear ribs roasted nuts and apples before the bonfire。 Our own Halloween seems to be a holiday by the Romans and the druids holiday blend made of。 Halloween activities in the original is very simple， and mostly in the church carried out。 However， in the whole of Europe， it is regarded as a Halloween enjoy slapstick， Jiangguigushi and a good opportunity to scare each other。 So people will no longer be used to praise this Autumn Festival， but it becomes supernatural， witches and ghosts festival。

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%.

I was a Hakka. I left my hometown Meizhou from my childhood. I followed my parents to this strange land and opened up our new home. As I grew up in this new environment, the impression of my hometown was gradually blurred. But in my mind, it cant forget the hometown dish of my childhood taste buds.

Many home dishes are famous far and near, and those special flavors have attracted a lot of people. One of the most famous dishes is "Mei Cai Braised Pork", my dad is a generation old Hakka love. Although it sounds like this dish seems to be difficult to get in good taste, but this dish is representative of Hakka peoples diligence and frugality quality.

My father said, "our hometown is Mei Mei Cai Braised Pork" single dishes there are many complicated steps. When the farming harvest, the farmers harvest the mustard, then put it in the sun to matured, and then take the food to the ground, arrange it, and sprinkle a lot of salt on it. According to my father, when they were young, they were trampling the dishes with clean feet after the salt was sprinkled. After the tread, put it in a vessel to a degree, then take the steam, then take the sun... So the three steamed three sun, the earthly plum dried vegetables!

"Mei Cai Braised Pork" another character is meat, meat to choose "pork fat pork". Making this dish, put the Mei food dry cleaning, cut thin pieces, the fat basin under the streaky pork belly pieces, Mei dish, steamed for a long time, fat oil seeping into the plum dried vegetables, plum dried vegetables fragrance dipped into fat, opened a pot. Hot, delicious food Braised Pork pan mei! A pot of delicious food Braised Pork Mei can eat for a long time, because the salty, not perishable. A small pinch to the bowl, the fragrance of the four spilled, can pick up a few rice, that taste, to taste to understand. Such a dish reflects the diligence and frugality of the Hakka people, which is the favorite of the Hakka people.

When I heard my Dad talking about his hometown dishes, dad was fun, innocent, and rich in homesickness. In my fathers age, and cant eat "Mei Cai Braised Pork", to wait until the new year will kill pigs, so have a good heart is also waiting for Spring Festival to eat.

In my opinion, McDonalds and Kentucky fast food are far more infatuated than this dish. Maybe it is because I have not experienced the father of that era, cannot understand a dish not easily won; perhaps because there is no contact with the home, can not understand the charm of home cooking; perhaps because now no children of that age as difficult as father, do not know how precious home cooking. But from my fathers love for home food, I read the charm of my hometown cuisine, and I also fell in love with home food.

Home of the most round moon, home of the most tea, home wine is the most alcohol, home food is the most lingering.

Why, you may wonder, should spiders be our friends? Because they destroy so many insects, and insects include some of the greatest enemies of the human race.Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals.We owe a lot to the birds and beasts who eat insects but all of them put together kill only a fraction of the number destroyed by spiders.Moreover, unlike some of the other insect eaters, spiders never do the least harm to us or our belongings.

Spiders are not insects, as many people think, nor even nearly related to them.One can tell the difference almost at a glance, for a spider always has eight legs and an insect never more than six.

How many spiders are engaged in this work on our behalf? One authority on spiders made a census of the spiders in a grass field in the south of England, and he estimated that there were more than 2,250,000 in one acre; that is something like 6,000,000 spiders of different kinds on a football pitch.Spiders are busy for at least half the year in killing insects.It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day.It has been estimated that the weight of all the insects destroyed by spiders in Britain in one year would be greater than the total weight of all the human beings in the country.

你可能会觉得奇怪，蜘蛛怎么会是我们的朋友呢?因为它们能消灭那么多的昆虫，其中包括一些人类的大敌。要不是人类受一些食虫动物的保护，昆虫就会使我们无法在地球上生活下去，昆虫会吞食我们的全部庄稼，杀死我们的成群的牛羊。我们要十分感谢那些吃昆虫的鸟和兽，然而把它们所杀死的昆虫全部加在一起也只相当于蜘蛛所消灭的一小部分。此外，蜘蛛不同于其他食虫动物，它们丝毫不危害我们和我们的财物。

许多人认为蜘蛛是昆虫，但它们不是昆虫，甚至与昆虫毫无关系。人们几乎一眼就能看出二者的差异，因为蜘蛛都是8条腿，而昆虫的腿从不超过6条。

有多少蜘蛛在为我们效力呢?一位研究蜘蛛的权威对英国南部一块草坪上的蜘蛛作了一次调查。他估计每英亩草坪里有225万多只蜘蛛。这就是说，在一个足球场上约有600万只不同种类的蜘蛛。蜘蛛至少有半年忙于吃昆虫。它们一年中消灭了多少昆虫，我们简直无法猜测，它们是吃不饱的动物，不满意一日三餐。据估计，在英国蜘蛛一年里所消灭昆虫的重量超过了这个国家人口的总重量。
