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。

Recently, I was so shocked by the news that a young boy died of violence

after his parents sent him to a private school. The slogan of the private school

was to help parents correct kids bad behaviors. A lot of parents choose to send

their kids here after they giving up educating their kids. The public blamed the

parents for not educating their children in the right way. There is no doubt

that the root of kids problems come from family. Many parents always force the

children to do what they want and ignore the kids feelings, so they will go

against the elders thoughts. Finally, the parents lose temper. The elder should

show respect to the kids. Communication can solve the problem. When the children

receive love and understanding from parents, they will be nice persons.

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.

Today, I went to the grandmas home with my father and mother for the Dragon

Boat Festival. When we entered the door, grandma said, "today is Dragon Boat

Festival. Lets make dumplings." We promised. Grandma said, "bamboo leaves need

to be soaked for a while.

After a while, we began to pack the zongzi. Each of us picked up three

pieces of bamboo leaves, grabbed a handful of glutinous rice with our hands, put

them in the bamboo leaves, and put on some big red dates. And then wrap it into

a cone. Im glad to have a zongzi wrapped up. I said to grandma, "the dumplings

are so simple. Grandma said, "the real bag is not easy!" After finishing the

package, the dumplings were cooked.

Our whole family is very happy to eat sweet rice dumplings.

the goal and plan details in the library in group task. I have so many good

memories to study here, which makes me so happy. No matter which school I am in,

I will always find this quiet corner and study what I like. I love the feelings

there.

"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.

The cold air has come for a while, I stayed at my house all the time, as

there was nothing for me go do, I watched the movies. When I saw the beach and

sunshine in the movie, I miss the sunshine so much. Today is lucky for me, the

sun finally comes out, I decide to go out for a walk and take in the fresh air.

The breeze blows me softly, I can sense the coming of spring, I walk into a

coffee shop and choose a table which is near the window. I sit down and watch

people just walk by, I see all kinds of face expressions, I try to read them.

There is a girl who is talking to his boyfriend, maybe he is proposing her, I

can see from the girl’s sweet smile. There is another man sitting alone, may he

is waiting for his wife. I have a great time in the bright afternoon.

When it comes to success, different people have different opinions about

what makes it come true. Some people regard hard-working as an essential quality

to success while others believe being clever would lead to success. From my

point of view, I think perseverance and hard-working are indispensable for those

who want to make an achievement.

Firstly, perseverance let people step closely towards success. Most people

want to make a big difference to prove their value. People who set their goal

and keep moving would make their dream come true. However, there are some people

who set their goal but they stop at the difficulty would fail in the end. I

think the difference between success and failure is perseverance. If we have

perseverance, even if we are not clever, we will make a great difference, but if

we not, we are doomed to lose. As we all know, Edison is a great inventor in the

world. However, before he invented the bulb, he kept trying for tens of

thousands of times to find a suitable wire. Let us imagine, if he gave up at the

999th, then how he couldn’t become so successful. So, I strongly believe that

perseverance produces success.

Secondly, there is also a kind of people who are born with cleverness, I

think they are lucky. Nevertheless, if they don’t make a hard work on their way

to their goal, they, absolutely, will become loser. Whether we are gifted for

intelligent, we must be hard-working so as to success. I regard hard-working as

an efficient approach to be successful because I believe ‘pains and gains’. As

for those who do not make great efforts on work, failure follows. In old times,

there is a clever boy who can make excellent poem when he can talk. When his

father found the little child’s cleverness, he just let the child make poems to

show around while never let the boy learned anything. When the boy grew up,

people forgot him because he lost the ability to compose poems and became

ordinary as others. From this matter, we can see that only by hard-working can

we get knowledge and make a good future.

Anyway, I think perseverance and hard-working are both important in our way

to success for they enhance us and produce success.

I was born in the country, my family lived there before I was 6 years old.

Then my parents moved to the city for their work, I had to stay away from my

hometown. Though living in the city brings me a lot of convenience, I eat the

good food, I still miss country life all the time. I love to live in the

country.

Living in the country, the time seems to be very slow. I woke up early in

the morning and then took the walk. After eating the breakfast, it was about 8

o’clock. I went out to play with my friends or went to help my grandparents with

their work. After doing these, it was just 11 o’clock. But in the city, I woke

up at 9 o’clock, and then I ate the breakfast, the rest of the day was to play

computer. How time flies to me.

I get so close to the nature and I find so much fun in the country life. I

always want to live in my hometown. When I have the time, I will go back there

and enjoy the moment.

I am so looking forward to my college life. I have pictured it thousands of

times in my mind. The free lifestyle and lively parties are always appearing my

mind. The great expectation of campus life endows me a lot of passion to keep

study. After two years’ study, I would find my lifestyle.

The first thing for me is to learn more knowledge. Most students find a way

to release themselves and skip or sleep in the class. They think study is just

the task, so they give up improving themselves and take part in all kinds of

activities, which bring them great joy. The wrong conception about college stage

makes most students miss the best time to equip themselves with skills. I

realize my job and dare not to loose study.

The second thing for me to learn is to make friends by joining activities.

I am a shy girl, but inside my heart, I am so eager to make more friends, so I

choose to join many activities in the spared time. I learn dancing and playing

tennis. The lucky thing is that I know many nice people and we become good

friends, who make my college colorful.

Chinahas a very long and brilliant history, whose people are so friendly

and hospitable. But I am wondering why some people pay such little attention to

the environment and nature. In many places of the countryside, rivers have

become stinking sewers and brooks have disappeared. Heaps of garbage obstructs

the scarce flow of dirty water. The grounds are littered with plastic bottles

and bags. People are cutting down trees even though it is illegal. In some

towns, rubbish is hidden behind walls. Garbage cans are often of little use,

making cleaners must rush all day long and also by night to clean the

rubbish.

This lack of consideration for nature in general is extremely detrimental

to children’s education, toChina’s image, to public health, to tourism and to

the future.Chinais the common treasure of all Chinese, and we should live up to

be a member of this big family, a descendant of 5000-year-plus ancient civilized

country. I think the environment must absolutely be strictly protected by all

means. This protection should go at the same pace as the marvelous development

of the nation.

In this respect,Germanyis a rare model and leaves me a very deep

impression. After you have an exciting tour around in this country for a week or

so, it is unnecessary for you to polish your leather shoes. Personally, first of

all, the strong awareness of people’s environmental protection; then, the

advanced technology applied in the field of preserving the nature; We can learn

form others in building China into one of the most environmentally friendly

places in the world.

Most smokers are males, because they need to smoke for social communication

or for set themselves free from the pressure. In the packaging, we can find that

every packaging has written the words that smoking is harmful to health. Though

smokers know it, they ignore it. For the harmony of the family, people should

quit smoking.

To quit smoking is not easy, people know smoking does harm to their health,

but they just can’t resist the temptation and then start to smoke again, so they

must have strong will. They must tell themselves that smoking not only does harm

to their health, but also does harm to their families. The families will have

much chance to take in the second-hand cigarette, in order to keep the families

healthy, smokers must have the strong will to quit smoke.

When people find it hard not to smoke, their mouth will feel uneasy, they

want to smoke again. At that time, people can find some food or fake cigarette

to take place of the real cigarette, in the long time, they will have less

desire to smoke.

rom the books . sometimes , i was so deeply indulged in my resea rch that i

forgot my meals and time. now i have made great progress. several of my research

papers have been published . the methods proposed in my papers have been proven

to be valuable for the solution of some problems . i am very happy. the ladder

of becoming a scientist is still far ahead , but i have climbed the first rung

The Lunar New Year

The Lunar New Year occasion to the Chinese people. It lasts about the first four days of the year, during which people do not work except for the workers on duty. Students do not go to school, and shops are closed.

Several days before the new year, people begin to prepare. Farmers kill pigs, sheep, cocks and hens. City dwellers buy meat fish and vegetables. Houses are cleaned; couplets are posted on the doors. Colourful lanterns are hung at the gate.

On the eve of the new year, each family has its members gatherd together and eats a family reunion dinner. After the meal they watch TV until the clock strickes twelve. Then every family sets off long strings of small firecrackers and other fireworks to welcome the new year. On the first day of the new year, almost everyone is dressed in his or her best. Whenpeople meet on the way, they say to each other "Happy New Year". Friends and relatives pay new year calls and gives presents to each other. Children indulge themselves in games.

Today is fathers day, when I went to school, I heard my classmates were

discussing about what to buy for their fathers. Some suggested to buy food,

others wanted to do something special by themselves. At last, an idea occurred

to my mind, I could cook a dinner for my father. So I rushed home after class.

My mother was preparing dinner. I told her my idea and she supported me. I did

as what my mother told me. I washed the food and then cut the meat and

vegetable. I learned it was not easy to cook a meal. I finished two dishes

finally. My father was very happy to taste them. It was such a special

surprise.
