A kiln (窑) is a type of oven or furnace used to cure, harden, or burn certain materials. Depending onwhich materials are heated in it, a kiln may be square, tunnel shaped, or beehive shaped, and usually madeof brick or stone. 1. It may be set as low as sixty-five degrees to cure grain or as high as 3,200degrees to transform limestone to quicklime (熟石灰).
2.They have a variety of purposes. The cement(水泥) industry uses revolving kilns to heatand separate raw materials. Bricks, pottery, and china made from clay must be fired, or hardened, in kilns.Certain kinds of coal and wood must be kiln-dried before they can be used. Hobbyists use small kilns tofire a variety of ceramic(陶瓷) objects.
There are two main types of kilns. A periodic kiln, used to fire certain kinds of delicate china, is raisedto a high temperature and then completely cooled before its contents are removed. A continuous, or tunnelkiln contains several chambers, or zones, which heat, bake, and cool a product. Stacks of clay bricks movethrough a tunnel kiln on tracks. 3.
Gas, oil, and coal are all used to heat modern kilns. 4. But for special jobs, where cleanlinessand careful heat are important, kilns must be heated by electricity oven though it is more expensive. Smallkilns used in the home or in craft shops are also heated electrically because electricity is clean andconvenient.
5. When ancient people discovered that heat hardened some materials, they were able to makedurable household objects such as jugs and bowls.

This is our country, America. The country where everyone is supposed to have a shot at financial success. The country of dreams and ambition. Yet, caused by the endless pursuit of individual profit, our country is a mess. And we owe it all to capitalism.
We live in a society where people are forced to live without health coverage. A country where the poor can hardly feed themselves while the rich decide which one of their 10 homes to stay at for the night. All of these sad things arise out of capitalism.
Sadly, our country values little more than money. It motivates our decisions and even influences entire political parties. We have gotten to the point in society where a human life comes secondary to our financial security. Any rational society would value life above all else and realize that health is a basic human right. Yet in our world, money comes first.
I never once have claimed to be an economist and have no interest in debating the financial advantages of any economic system. Yet socialism surely looks better than what we have.
If we lived in a socialist society, we would be a country without such an unfair wealth distribution. We would value friendship over business and we would treat one another as humans. Most importantly, however, is that money would stop controlling our lives and we could act how humans should act.
Capitalism has created an “every man for himself” existence. Everything is a battle for limited resources and fuels. We have become so accustomed to the life value that we will do whatever we have to look out for ourselves. Yet is this really the kind of life we want?
We have become so illusioned. We are tired of the misdirection. All economic systems have their issues, but I feel like ours is turning our country into something it shouldn’t be. The good of man falls secondary to money. In our world, it is all about dollars and cents, which, unfortunately for most, makes no sense.

Over 130 schoolmates from the Society for Science & the Public’s high school science competitions gathered for a panel (座谈小组) discussion. Hosted by Society President Maya Ajmera, the panel consisted of science professionals and Society schoolmates.
Ajmera started the event by asking the successful women panelists about young scientists faced when entering the professional world.
Hackman, a health policy reporter for the Wall Street Journal, admitted that in following a career inscience, some scientists dislike the long, seemingly dull lab hours when they could follow a job with more“shine”.
About what was hoped for in their career, Angel, who founded Science from Scientists, encouraged the audience to ask themselves, “What influence did I have?

As for their support systems, they agreed on the value and support of the family in their professional development, Hackman shared her background as a first generation Iranian American and how her parents who knew little about science had fled the Iranian Revolution. While working with mother to complete herSTS project, Hackman was surprised and grateful because while her mother did not understand the research,her willingness to learn and help made all the difference.

Though not as much as in the past, grandparents are the teachers of the Navajo (纳瓦霍人) youth. They make young people aware of life at an early age. The parents allow them the privilege of teaching the children, and the grandparents take great pride in raising them.
Young children often stay with their grandparents for years at a time, developing a close and trusting relationship. The grandparents teach them Navajo legends and the principle of life, emphasizing both new culture trends and the preservation of traditions.
The grandparents are also the leading figure in teaching the youth the arts of weaving, caring for the live stock, using herbal medicine, and other arts and crafts.
The children are taught to respect their elders, care for them, help them and learn from them. Young people are urged to listen with care to the words of their elders and keep as much wisdom as possible. Grandparents often go to social gatherings and traditional events, and young people have opportunities to learn more about their culture and traditions.
I lived with my grandmother for thirteen years, and she raised me in the old ways of our people. Although I was going to school, she taught me as much as she could about our traditions. If I had a chance, I would listen again to her wise teachings, expressed with kindness in a soft voice that touched my heart.
We used to plant corn and pumpkin every summer. They never grew big enough to feed us, but we planted them anyway. I asked my grandmother why. She said, “Grandson, our plants will be far more beautiful than the flowers outside the fence.” I didn’t understand until one day I saw their beauty as I was coming over the hill with her. She said, “Anything that is a part of you is always far more beautiful than the things which you pass by.” We had some beautiful years together. I’m glad she is a part of me and I’m apart of her.
Children used to be well disciplined, possessing more respect for culture, traditions and beliefs than they do now. The world of the Navajo has been influenced by the western world, and the grandparents have less control and influence than they used to. But the young people who have been touched by their teachings have glimpsed a way of life beyond what most people know today.

Last night a strong wind as well as a heavily rain struck our area. News came that the trees in the park two kilometers away from our school was blown down. This afternoon, they set off the park to do some cleaning. The head of the park met us or gave us some advice on how to clear away the falling trees, branches and leaves. Some times later, we were working hard when it begins to rain. Because few of us had taken along umbrellas or raincoats, so we were all wet. A rain lasted about an hour and it was a pity that they had to stop our work.
