Knowledge can be acquired from many sources. These include books, teachers

and practical experience, and each has its own advantages. The knowledge we gain

from books and formal education enables us to learn about things that we have no

opportunity to experience in daily life. We can study all the places in the

world and learn from people we will never meet in our lifetime, just by reading

about them in books. We can also develop our analytical skills and learn how to

view and interpret the world around us in different ways. Furthermore, we can

learn from the past by reading books. In this way, we won’t repeat the mistakes

of others and can build on their achievements.

Practical experience, on the other hand, can give us more useful knowledge.

It is said that one learns best by doing, and I believe that this is true,

whether one is successful or not. In fact, I think making mistakes is the best

way to learn. Moreover, if one wants to make new advances, it is necessary to

act. Innovations do not come about through reading but through experimentation.

Finally, one can apply the skills and insights gained through the study of books

to practical experience, making an already meaningful experience more

meaningful. However, unless it is applied to real experiences, book knowledge

remains theoretical and, in the end, is useless. That is why I believe that

knowledge gained from practical experience is more important than that acquired

from books.

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

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.

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.

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.

What do you usually do in your spare time to relax yourself? Let me tell

you some ways to.First of all, you can stay in bed for a while, sleeping makes

people feel good.Secondly, you can join your friends in some fun parties, talks

with friends will let you feel comfortable.Thirdly, you can go outing alone. You

can either breathe new fresh air in the mountains or you can take a look at how

beautiful the nature looks like.Fourth, why dont you just play sports with your

family? Youll feel tired if you do too much exercise once, but it keeps you

healthy and energetic.Whats your opinion?

Before I went to middle school, I lived with my grandparents. At that time,

I stayed in the country, which was the most beautiful place for me. Early in the

morning, I walked along the country road, appreciating the fresh air. We raised

a little dog. He was my best friend, and he accompanied me all the time. No

matter what I did and where I went, the little dog was with me and I loved him

so much. Sometimes I would pick up the fruit in the garden, sometimes I would

catch the fish in the clear river. It was such a happy childhood for me that I

will never forget.

When the national entrance examination is over, people always pay more

attention to those who are enrolled by colleges and universities. Those who

failed the examination are treated coldly. Being enrolled by colleges and

universities is, of course, worth congratulating. But giving the successful

candidates excessive praise and neglecting those who failed the examination

might send the wrong message: young people do not have a bright future unless

they go to college or university.

Teachers, parents and society, therefore, should give more attention to

students failing the examination. They are in more urgent need of understanding,

warmth and encouragement. We should tell them that to go to college is not the

only way to success, and that, if they make enough effort, they can still

develop talents in other occupations that will serve society.

Personally, the country’s economic development requires not only

specialized scientists and technical experts, but also knowledge-based workers

and skilled laborers. After some vocational training, these senior high school

students can also become backbones in their own fields and contribute their

wisdom to our society.

Earthquake is one of the most severe natural disasters. Its shaking of the

ground caused by the sudden breaking and shifting of large sections of Earths

rocky ourter shell. Its results can be very horrible. The Wenchuan Earthquake in

2008 and Japan Earthquake in 2011 are the most severe earthquakes in recent

years, causing huge casualties and property losses. But earthquakes almost never

kill people directly. Many deaths and injuries in earthquaking result from

falling objects and the collapse of buildings

When I got settled, the total use of the microwave to do their own things

to eat. One day, my father saw me, I am afraid to say that I grew up as a cook.

I immediately shaken like a rattle-drum head, you said : "That is not my ideal.

When I grow up I want to IT (information technology) industries. "Yes, I bought

a computer five years ago after his father, I am familiar with it day by day.

Until last year, and I have formed a deep bond with it. From then on, I want

success in the information technology industry to make contributions to the

cause of national computer. But my father said I could only do in the field

"testing the game," is what the new game, and always let me play with, the

report there will be any games. I think what he said is not their fault, I

always play games recently, those who do not have a veteran like Flash. In

recent days, I sprouted out of a bad idea : I will be playing the game that the

network server to the black. My account will revise the highest level. However,

I Xiangliaoyouxiang, this is wrong, but was caught by the police network is not

good. When hackers but also need high computer skills. As a member of the IT

industry is my ideal, I would like to advance this goal, to improve their

computer skills

当我闲得没事时，就总自己用微波炉做点东西吃。一天，爸爸看见我这样，说我长大恐怕是要当厨师了。我立刻把头摇得像拨浪鼓似的，说：“那不是我的理想，我长大想做IT(信息技术)行业。”

没错，自从五年前爸爸给我买来电脑后，我就一天天地熟悉它。到了去年，我已经和它结下了不解之缘。从那时候开始，我就想要在信息技术行业取得成就，为国家计算机事业做出贡献。

可是爸爸说我在这个行业中只能做“游戏测试员”，就是什么游戏新出来，总是先让我玩玩，报告游戏中有什么错误。我觉得他说的没有错，我最近一段时间老是玩游戏，那些FLASH之类的老也不用了。

最近几天，我萌生出了一个不好的想法：将我玩的那个网络游戏的服务器给黑了，将我的账号修改成最高级别。可是，我想了又想，这样做是不对的，而且被警察抓到也是不好的。而且当黑客也需要很高的电脑技术的。

成为IT行业的一员是我的理想，所以我要向这个目标前进，提高自己的电脑技术.

Last week, I saw a very impressive documentary about panda. A professor

studied panda in the early 1980s went to the wild life and kept trace of wild

giant panda for many years. As a result, he found that it was human being that

made these lovely animals die out. At that time, many people believed that giant

panda became less because of the low rate of newborn babies. But it was not

true. People cut trees for making profit at that time. Panda lose homeland and

they lacked of food. Thanks to these valuable data, the government took the

policy to protect the animals. So today, the number of giant panda is

increasing. People realize the importance of protecting the environment and it

is the best way to protect wild animals, they are the indispensable part of the

nature.

Since its rise, the Internet has been playing a more and more important

role in our daily life. It brings tremendous convenience and efficiency to our

lives. Online shopping is also a new rising thing brought by the Internet. Since

its increasing developing speed, some people think that online shopping will

replace traditional shopping. However, as far as I am concerned, it wont happen

in a short time.

Although online shopping is really very convenient, there are still some

strong points of traditional shopping which cannot be replaced by online

shopping. Firstly, online shopping lacks the intuitional impression of goods.

Sometimes the photos offered by the sellers are beautified with softwares, and

you will be disappointed to find the actual item is far from your expectation.

Secondly, returning goods in online shopping is quite troublesome, and sometimes

you only can achieve your goal at the cost of the payment of the postage by

yourself. Finally, there are too many fake products and cheats in online

shopping, and the quality of goods cannot be guaranteed as those in traditional

shops.

According to the points above, online shopping still needs some

improvements to totally replace the functions of traditional shopping. However,

the potential of online business is so huge that it will certainly take a great

share in the trade market.

Now more and more bike sharing brands have emerged, such as ofo, Mobai,

Wukong bicycle, Xiaoming bicycle and so on, which are convenient for our travel.

As long as we download a software, we can pay some money to rent a car. However,

since I saw some phenomena, I have asked myself, "is bike sharing convenient or

harmful?"

Bike sharing is very popular recently. Ofo software or other sharing

software can be found in almost all mobile phones of "mobile phone family".

However, once my mother came home full of anger, scared me to speak. I shuddered

and asked, "Mom, what makes you so angry?" She put the bag in her hand on the

table and made a loud "pa -". "Your sister helped me install an ofo software in

my mobile phone. I wanted to make it easy to ride back with good medicine, but

today I rented a" broken car "!" I was puzzled: "ofo still has a broken car

"That is, otherwise, how could my feet be bruised?" She moved her foot to me,

and a black wheel mark was still visible. "When I was riding, the chain was

loose. If it wasnt for my fast braking speed, I would have fallen off!" Since

then, Ive been less fond of bike sharing.

Once I went to a make-up class, I saw two workers sitting on a Mobi

bicycle, shaking and laughing. Dad was very indignant and said: "this kind of

person really does not speak of public morality! Make fun of the public car I

know that they wont do this with their cars. My heart is like bleeding. Why,

they want to "bully" bike sharing.

Once I went out to play. The weather was very good and I was in a good

mood. I look up to the side, really do not see do not know, a look scared. A man

secretly removed the wheel of an ofo and replaced it with a bad one on his own.

After that, he rode off on the ofo wheel. Only the ofo little yellow car was

lying alone, and the wheels were not installed properly. It is like a injured

little girl, whose legs have been taken away, like vanca, can not endure the

sunshine of life. At that time, my tears began to drop. Is bike sharing "shared"

or "exclusive"?

There have been news reports that a boy under 12 years old riding a shared

bicycle was run over by a car and killed. At that time, the boys mother shared

the companys money to compensate for her sons death. Its clearly her sons fault.

He didnt ride a bike before he was 12 years old. I didnt say he deserved it. But

the fact is better than eloquence. The death of her son is not the

responsibility of the sharing company, but his own fault!

I once saw a young man riding ofo without scanning the code. A middle-aged

man pushed ofo into his home. Have you ever seen someone use Mobi without

decoding as fitness equipment? The sound of chain jingling is like a demon with

a chain in his hand crawling out of hell. Thats selfish!

Someone took an image that put the broken ofo and Moby together to fill a

small parking lot. After riding shared bicycles, people park them on the side of

the road at will. As long as a passer-by gently knocks down a car, it will fall

down like a domino.

Have you ever thought that sharing resources is closely related to each of

us, but all the harm they bring is due to selfishness. Bike sharing is just one

example. Ive seen shared bookstores where people leave books on their desks

after reading, so that they cant go home. "Convenience to others, convenience to

oneself." As long as we are convenient for others, we will also benefit

ourselves.

Over the last page calendar in 2010, time wheels and leave a deep imprint.

With winter snow after the warmth of the sun, in the joyful mood, 2011 to keep

the New Years day.

New Years day, is a connecting link between the preceding and the node.

The New Year is about to begin, standing on new starting point, the aftertaste

is past, have heavy harvest; Looking ahead, waiting for us is the beautiful

future. After a busy year of you I, can at this time to make a little stay,

close your eyes, bathed in sunshine, enjoy harvest thick feeling. From this day

started again, we will have a new targets, and on a one-year new journey.

The grass sprout out of the earth, clouds scud across, and year after year,

annual similar different. But, has not changed for New Years day is my

expectation.

When I was young, every New Year comes a few days ago, the morning wake up,

the first thing is bare bottom from woli leafing out of nowhere, then this

calendar day several times of snapping to finger countdown. Young Im such a

keen on New Years day this festival, in fact, only to have something good food,

new clothes to wear, but also need not go to school.

New Year dyed the our happy childhood, pulled close distance we grow up.

Slowly, I from elementary school, junior high school, arrive at the university,

blossom years as accelerated film a flash and pass. This years New Years day,

we are in a busy spent, work overtime everyday, we need to make very late. In

order to finish the task smoothly, we are often a pack of instant noodles, a

computer, four people take turns input. In order not to delay working, teacher

Chen just will just go to the kindergarten children locked in the home. The

nearest xiaoliu has also been no home, and together we live in the dormitory,

have a meal. Less childhood innocent romance, much work responsibility, also

enjoy our work of fun. During, no one has complained, increasingly mature we use

special ways of enjoying the unique New Years day holiday. As a word that said:

"even though we cannot stop the passage of time, but we can dominate oneself

mood."

New Year, new opportunities, we need a new struggle. Wind is being tidal

flat, hereunder sails; No matter what happens, the more must be quickened his

horse. In the New Year, let us follow temple head, with the development of steps

to the glorious future -- -nikita Khrushchev and walked on.

November 11 is Bachelor’s Day, it is a joke that shopping can make up the

loneliness on that day, the manufacturers sense the great business, so they give

great discount on that day, people are attracting by the discount, they buy a

lot of things on that special day. But we known that people lose their wisdom

when they buy things, most things are useless.

Today, shopping online brings great discount, the price of the product will

be cheaper online, so people like to shopping online. When the holiday comes,

the products even get cheaper, customers always wait for the chance to pay the

lower price. It is said that as so many buy things on Bachelor’s Day, the

express delivery congested, customers got their stuff very late. It is more

ridiculous that a couple divorced because the wife bought too many things

online.

Now December 12 is coming soon, the discount is being presented, it is a

great lure that customers can’t control themselves. Shopping online should be

rational, we just buy what we need, the rest even is cheaper, but without value,

we must realize is a waste.

Now, we can get cheaper stuff not only online, we should control ourselves,

we buy what we are using, we can use the money to do meaning thing.

Far and away the most important holiday in China is Spring Festival, also

known as the Chinese New Year.

To the Chinese people it is as important as Christmas to people in the

West.

The dates for this annual celebration are determined by the lunar calendar

rather than the Gregorian calendar, so the timing of the holiday varies from

late January to early February.

To the ordinary Chinese, the festival actually begins on the eve of the

lunar New Year‘s Day and ends on the fifth day of the first month of the lunar

calendar. But the 15th of the first month, which normally is called the Lantern

Festival, means the official end of the Spring Festival in many parts of the

country.

Spring Festival is the most importantand popular festival in China.Before

Spring Festival ,the people usually clean and decorate their houses.And they go

to the Flower Fairs to buy some flowers.

During Spring Festival ,the adults usually give lucky money to

children.People often get together and have a big meal.Some people eat dumpling

for dinner.

I love Spring Festival .

Now many students of Grade 9 are under too much pressure. They always feel

too tired to listen to the teachers carefully in class.

It’s important for students to relax. Only in this way can they study well

and be healthy. Here are some different ways to relax themselves. For example,

they can try to have enough sleep,or they can listen to their favourite music

after class. They can also read some books or do some sports. For me, I often

hang out with my friends.

While you are studying, don’t forget to relax. You will study better after

a good rest.

Today, with the development of Internet, many traditional ways of life have

been changed, especially the way to pay for purchase. The record of credit

occupies important role for everybody, and they need good credit to get loan, so

as to start their business or buy a house. We have come to the age of

credit.

There is a very classic example about the importance of credit. A Chinese

man took the train in Europe. He found no one checked the ticket, so he just

skipped the ticket. He thought he had saved the little money, but when he came

to the bank and wanted to get the loan, he got rejected, because his record of

credit showed he had skipped the ticket, which made him the unreliable man.

The record of credit is the main basis when people asked for loan. The

banks consider the account of money they would borrow according to the credit,

or the departments will check a person’s credit to see if they want to hire him.

The age of credit asks for us to behave ourselves well, or we will live the

tough life.

Once upon a time, I did not pay for my bill when I bought a pen, because

the boss forgot to charge me, so I pretended to not realize it and just walk

away with the pen. Many years passed, every time when I think of it, I will be

ashamed of myself, I lost the important thing once, but I will not lose it

again.

The merit of honesty occupies great importance today. In the old time,

without the camera’s supervisor, people kept their honesty according to their

self-consciousness. It seems that if they are not honest, they would not get any

punishment. But today, as the technology develops, people are supervised by the

high-technologies all the time, once they are caught cheating, their files will

have the spot, which affect their career badly.

We are living in the modern life, we need to self-behaved, what we do is

under the invisible cameras’ watching. Even we make the small mistake, we will

be recorded without noticed. What we do decides what kind of person we are, so

let’s be an honest person all the time.

I will soon become a middle school student, which means my life will come

to a new chapter. So I must do something different to make me stronger. I want

to be more independent, so I can make my own decision. As my parents always make

decisions for me, I want to tell them that I have grown up. From now on, I

should learn to take care of myself, such as washing clothes and helping my

mother with the house work. The most important thing is to finish my homework

without my parents supervision. I am so excited about my new life and I believe

that I can become a better person.
