Marine biological environment is a complex system including sea water, sea

water, soluble matter and suspended matter, seabed sediments and marine

organisms. The rich biological resources, mineral resources, chemical resources

and power resources in the sea are indispensable human resources treasure

houses, which are closely related to the survival and development of

mankind.

At present, the main objective of marine conservation is to protect marine

biological resources so that they can not be exhausted for sustainable use by

mankind. In particular, priority should be given to the conservation of marine

animals that are valuable and endangered. According to the UN investigation, due

to overfishing, mangrove accidental killing of non target to allow the killing

of marine organisms, the coastal engineering construction, deforestation,

pollution of the marine environment in general, at least 25 of the worlds most

valuable fisheries resources consumed, whales, sea turtles, manatees and many

other marine animal faces the danger of extinction. It is expected that with the

expansion of marine development, it is possible to cause more damage to marine

biological resources.

Marine protection task should first stop on the marine biological resources

excessive use, secondly to protect the marine biological habitat or habitat,

especially their migration, spawning, feeding, avoid Huahai coastline, beaches,

estuaries, coral reefs, to prevent heavy metals, pesticides, oil, organic

produce and eutrophication. Nutrients such as marine pollution. Maintain the

ability of regeneration of marine biological resources and the natural

purification ability of the sea water, maintain the marine ecological balance,

and ensure the sustainable development and utilization of the marine.

Today, with the development of high-technology, we can get access to all

kinds of high-tech products, such as computer, digital cameras and so on. These

products make our life more convenient, we can keep in touch with family and

friends any time any where. Our life has been changed by the high-tech, we live

in a fast-pace world. Cell phone influences our life deeply, everyone owns it.

While cell phone brings many dangers. First, cell hone contains radiation which

hurts people’s body. Today, more and more people die of cancer, the main reason

is that the high-tech products radiate their bodies, in the long run, the bodies

get sick. Cell phone is one of such products, it hurts our bodies as long we use

it. Second, cell phone distracts our attention about discovering the beauty of

life. People pay their attention on cell phone, they count on it by reading news

and making friends, being less going out. We should use cell phone properly.

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿，而且因为缺水而干渴。对你来说这可能似乎奇怪：因为我们的地球表面75%由水覆盖着。但是，这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下，和其他来源的淡水供人们饮用、使用。即使如此，这3%的水源我们也不能够完全使用，因为有些淡水是以冰山或冰河的形式存在。更糟糕的是，一些水源已遭受了污染。

然而，尽管按现状看来，这些少量的淡水即使时常转化成雨水的形式，对我们来说，也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91，000升水，你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行，但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言，与空间站不相上下。

21st century is the century of technology. Nowadays, technology is

everywhere around us. The development of technology has a significant affact

toward the society. Several technologies that we usually use are the internet,

computer, and cellphone. These new technologies make our life much easier and

better.

First, the development of computer changes our life. Decades ago, people

needed to do lots of complex calculation on hand because they did not have

computer, and more obvious, they did not have the software for calculation. As

the result of that, people spent hours on the equations that a computer can

solve in just a minute. Since the development of computer, people are able to

use some kind of software to compute lots of complex functions and mathematical

calculation. Computer becomes the most helpful equipment for the sciencists

because they can use their time more efficiently.

Also, internet is another useful tool for us today. The development of

internet brings a great impact toward the society. Instead of going to library

and fliping all the books to figure out some information, we can just simply use

a mouse and click on the website to do research. The internet leads us to a

place where we can find unlimited information and resources. It makes our life

much easier and better.

The last technology is cellphone. Nowadays, many people have a cellphone.

But it just appears on the market for about 10 years. It is very convenience to

the users because we can talk to anyone we want with a phone as small as a

wallet. Also, we can communicate with others by making a phone call instead of

sending letters. It is very fast and useful way to communicate.

In conclusion, I believe the development of technology brings significant

impact to our life. It is very helpful to us and I believe technology will keep

improving in future.

My dad bought a computer when I was five years old. I could draw pictures

and listen to music on it.

But once, the computer was down suddenly.

My dad told me that it might be attacked by computer virus.

I was so scared that I asked dad anxiously, "Did it get a flu? Did it need

some medicine?" But dad laughed and said smilingly, "Dont be silly, son.

No medicine can cure a computer virus. Its a problem of program." I didnt

understand what my dad said at that time.

But I made up my mind to study hard and to be a computer expert in the

future.

Every four years, the Olympic Game will catch the world’s attention and the

players from all the countries take part in this big match. First of all, for

the great honor, they fight for their contries. Second, they fight for their

families. Many years ago, a female gymnast caught people’s attention, it was not

because she was beautiful, instead, she looked much older than the other

players. She was a mother. A lot of people wondered why she did not retired.

When the media interviewed her, what she said moved all. She did this for her

young son. Her son was very sick and she needed the money to keep the long-term

treatment. She is a great mother, people admire her and they would like to give

their hands to her. Now her boy has recovered, but this mother still insists,

because she loves this sport.

As a Senior Grade Three students, I am very busy in preparing for the

college entrance examination. I have seven classes a day, and two self-study

classes at night. And only a day left for the weekend. So, most of the time I

have to spend on the study, after all the college entrance examination is very

important for almost all of us. Aside of study, I would play football with my

friends after school and the weekend. I like playing football very much. When I

run on the football field, I can put the examination thing off my mind for a

while, only sweat and laugh left. It is a good exercise for health and a good

way to relax from the busy study too. This is my high school life, busy and

fulfilling.

When i was in high school, I had to study all the time and hardly had spare

time to do what i wanted to.Besides, I had to focus on my textbooks and doing

exercise again and again. Therefore, I had little time to read magazines and

novels and watch TV. what was worse, I couldnt play with my friends a lot, which

I couldnt stand the most. In a word, all i did in high shool should be

considered for the College Entrance Examination.

However, my college life is totally different from the life in high

school.I can arrange my time freely. I spend most of my time reading in the

library, where I can open my eyes and broaden my mind.In my free time, I also

join some clubs,where i can make a lot of friends of different majors. My

teachers in college are so kind and knowledgeable that they not only teach us

knowledge but also how to be a person and how to get on with others. In

addition, there are more opportunities for me to improve myself.

I believe college life is an important stage in my life. In college, i can

learn how to learn by myself, how to get on with others, how to live

independently.College provides me with a stage where i can show myself and be

myself.

When a guest comes to my home from afar on a cold night, I light bamboo to

boil tea to offer him. Ancient Chinese poem.China is the home country of tea.

Before the Tang Dynasty, Chinese tea was exported by land and sea, first to

Japan and Korea, then to India and Central Asia and, in the Ming and Qing

dynasties, to the Arabian Peninsula. In the early period of the 17th century,

Chinese tea was exported to Europe, where the upper class adopted the fashion of

drinking tea. Chinese tea like Chinese silk and china has become synonymous

worldwide with refined culture. At the heart of the culture of tea the study and

practice of tea in all its aspects is the simple gesture of offering a cup of

tea to a guest that for Chinese people today is a fundamental social custom, as

it has been for centuries.China traces the development of tea as an art form to

Lu Yu, known as the Saint of Tea in Chinese history, who lived during the Tang

Dynasty and who wrote The Book of Tea, the first ever treatise on tea and tea

culture. The spirit of tea permeates Chinese culture, and throughout the country

there are many kinds of teas, teahouses, tea legends, tea artifacts and tea

customs. Better-known places to enjoy a good cup of tea in China include Beijing

noted for its variety of teahouses; Fujian and Guangdong provinces and other

places in the southeast of China that serve gongfu tea, a formal serving of tea

in tiny cups; the West Lake in Hangzhou, also the home of the Tea Connoisseurs

Association, noted for its excellent green tea; and provinces in southwest China

like Yunnan where the ethnic groups less affected by foreign cultures retain tea

ceremonies and customs in original tea-growing areas.

As the summer vacation comes, I decide to learn swimming, because the

weather is so hot, I can make myself cool, what’s more, I want to master another

skill and protect myself. Many people lose their lives when they meet the

accident in the water, so it is important to learn swimming. I have made up my

mind and must finish this task.

When girls get together, they like gossip. They always talk about the topic of beauty. They will discuss who is the most beautiful girl in school or they will compare the girls and see who is more charming. As the young people, they usually judge people from appearance. The definition of beauty of course is the one who is thinner and has the pretty face. When they ask me which one is more attractive, then I will look at them for a while, because I want to perceive their personality. My view on beauty is not only from appearance as I think most girls have the pretty faces, but also from the inside, only the quality that differentiates them. The pretty faces will fade away anyway, only the quality that helps people to keep charming. So we need to cultivate the good quality.

女孩喜欢八卦，当她们聚在一起时，总是谈论美的话题。她们会讨论谁是学校里最美丽的女孩或者比较谁更有魅力。因为年轻，所以她们通常是从外貌判断一个人，理所当然的认为美丽的定义是瘦跟漂亮的脸蛋。当她们问我哪一个女孩子更有魅力的时候，我会看一会，因为我想想想她们的品行。我觉得大多数女孩都有着漂亮的脸蛋，所以我认为美不仅是外表，还有内心美，只有品行能把她们区分开来。漂亮的面孔会逐渐老去，只有品行可以永远保持魅力。所以我们需要培养良好的品行。

As we all known，food safety problems are more and more popular in our

country，because more cases about food safety problem have appeared.

Firstly，As the old saying goes，the food is what matters to the people。 Food

plays an important role in peoples life。So food safety influences peoples

health and life。Secondly，some producers only think about earning money without

thinking about ensuring food safty。they produce unqualified food.Thirdly， some

food supervisory departpents dont perform their duty pletely。This behavior make

some producer ignore the safety of production.

If we want to solve problems that is illustrated former，we must call on the

supervisory department to manage the food market.And the producers must paly

their roles。 Lastly， we hope that there is law that punish illegal acts.

Myhometownis a beautiful place with a pupulation of eight million.It

stands beside the Gulf of Bohai.

Tianjin has many high office and commercial buildings and wide tree-lined

streets.Several excellent world-famous institutions of higher learning are

located here,namely Nankai University and Tianjin University.As a most important

industrial center for North China,her hundreds of factories and joint ventures

with foreign companies manufacture a wide range of top-grade and high-tech

products or consumer goods.Many of these products have attained or surpassed

world levels.Markets and department stores,big or small,are well-stocked with

all kinds of goods,which are high in quality but low in price.

But in the old days,Tianjin used to be a poor and backward city

characteristic of semi-colonialism and semi-feudalism.The few rich persons lived

in luxury houses while the majority of the working people lived in old,shabby

huts or buildings on narrow and muddy streets.The working class led a very

miserable life.

Today people in Tianjin are going all out to build their city into a

beautiful and prosperous place to live in.

The traffic problem is one of the most serious problems in my hometown.

Recently, more and more people have private car, but the roads are so narrow

that we have to fight against the heavy traffic when we go out. Especially

during the rush hours, cars and buses are unable to move. To make things worse,

many people are killed in the traffic accidents. How miserable it is!

For the sake of our life and security, some measures must be taken to

change the present situation. In the first place, as there are a great many

cars, we should control the number of private cars and vehicles and use the

public transportation more often. Secondly, the government should widen the

roads and build more flyovers, so as to ease the traffic pressure and reduce the

traffic accidents. In addition, the undergrounds and light rails should be

constructed, so that we can have more choices when going out and do not have to

worry about the traffic jams in the future.

I believe the traffic problem could be solved if we devote our actions to

them.

As we know, many people favor the idea that the college life is free and

comfortable, but I’d like to say it’s not true. As a matter of fact, my life in

university is so busy that I wonder if my energy is enough. As to my college

life, I divide it into four parts, including study, student activities, library

and the others.

Firstly, I want to talk about the study. In my opinion, study is the

priority in college. When I received the letter of admission in summer, I knew

clearly that what I should do. So I make up my mind to study hard and pursue

learning as much as possible. I’m greatly convinced that knowledge can change my

life. Therefore, I often go to the quiet study room where many people study

there. By working so hard, I get good grades in the exams.

Secondly, student activities play an important role in our college life. To

be honest, the student Union is a good place where one can develop social

skills, get his abilities trained. I take part in many student activities. For

example, I’ m a volunteer, teaching the kids to learn to dance and write. I

think it’s meaningful for everyone to give a hand to others. I can also do some

jobs in the Student Union, including receiving and sending fast mail, selling

papers and magazines. I think they’re unforgettable and worthwhile experiences

for me.

Thirdly, I also visit the library constantly. It’s said that “shelves of

books, oceans of knowledge”, so I read books that I’m interested in. In this

way, I can share stories with my new friends and it also changes my horizons

.When I’m sad, lost or in trouble, staying the library makes me quiet and

comfortable. After all, every life has bad moments as well as good ones, and the

library for me is a support in bad moments. So it’s wise choice for me to stay

in the library.

Finally, I often do other things in my spare time. In order to alleviate

parents’ burden, I often do some part-time jobs and write some articles to earn

money. It helps me to be independent and improve my social skills.

In short, my life in university is busy but valuable. You can see that

study brings me knowledge, student activities improve myself, library changes my

horizons, the others things make me independent. They get all my abilities

trained. And I see that the chance will come only if you have a prepared mind,

so I’m sure that I can achieve my dreams in college life.

As summer vacation is coming, my parents have made some plans for me,

because they want me to learn something useful. This first thing they want me to

do is to learn swimming. This is an important skill. It can save my life if I

fall into the water. I also want to learn swimming, so that I can do many cool

sports. I am so excited about the lesson.

Hometown is the place where a person belongs. Chinese people have special

feelings about their hometown. No matter where they go, they won’t abandon it

and always make some time to visit. My hometown brings me so many happy memories

and I wish it could keep its original face forever.

Two years ago, I lived in my hometown. It is a small village, so people

there get familiar with each other. When we walked on the country road, everyone

smiled when we saw each other. There was no distance for us. In the daytime, I

liked to go boating in the small river with my friends, or sometimes I could

catch fish. The green trees around me and I could hear the birds singing all the

time. It was a paradise for me.

However, even the small paradise can’t avoid being polluted seriously. The

environment is no more clean, the river becomes smaller and the water is so

dirty. When I see this, I feel so pity. If we lose the clean land, how can we

survive for long. Protecting the environment is in need.

Teacher is a great job in most students’ eyes. When they are asked what

they want to be in the future, most will say they want to be a teacher and make

a contribution to the society. Indeed, we have access to the teachers all the

time and they have great influence on us. So being a teacher is a ideal job for

most students, but for me, I want to be a librarian. I like reading books so

much and once I have time, I will be immersed in these novels. Books broaden my

vision, though I can’t travel to the places, I can still know about these famous

sites from these books. Being a librarian can make me have a lot of time to

read.

August 15th in Chinese Lunar Calendar is the Mid-Autumn Day. It is one of

the most important traditional festivals in China.

On that day people usually go back home to have family reunion . Each

family will have the members get together to have a big dinner. The most popular

food is moon cakes. They are round and look like the moon.

The moon is the brightest this night. People eat the delicious food while

they are enjoying a beautiful full moon in their yard. At this time, some old

people would like to tell many past events and tell the children a story about

the rabbit on the moon . The children really believe that there is a rabbit on

the moon. They hope to go to the moon and have a look one day.

What a great festival!

中秋节

农历八月十五日是中秋节，在中国它是最重要的传统节日之一。

在那一天，人们通常回家与家人团聚，一家人聚在一起饱餐一顿。最流行的食品是月饼，它们圆圆的就像月亮。

中秋节晚上的月亮特别地圆。人们都在自家的院子里一边赏月一边吃着可口的月饼。这个时候

，一些老人会讲述许多古老的故事，如月亮上的玉兔，孩子们信以为真，他们真想有一天登上月球看个究竟。

中秋是个美好的节日啊!

It was Mother’s Day. Sun Zheng thought he should do something for his

mother. He decided to help his mother do some housework. After school he went to

a shop to buy some food on his way home.

When he got home, he did his best to cook some nice food,though he couldn’t

do the cooking well. Thenhe cleaned the room. He felt very tired, but he was

very happy.

When his father and his mother came back and saw the clean rooms and dishes

which weren’t so nice, they were very happy.They had their supper together. His

mother said, "Thank you,my child!"

People will be the envy of the sky eagle, but never thought it a thousand

times to practice hard; people were envious of butterfly flowers, but do not

have to pay attention to it once as a caterpillar suffering; people are jealous

of those celebrities, those scientists, those successful people, but never

thought they have too much to pay behind the hardships and sweat, experienced

many setbacks.

So, in the face of the unexpected blow, who seem insurmountable

difficulties, the vast expanse of the thorns, I will not retreat. Because I

know, success is built on the basis of failure and sharpening.
