hello! i wonder whether everybody knows the meaning of these two words of “ energy-conservation ” and “ low carbon ”？ i assume as a matter of course and know. does “ energy-conservation ” save the energy? does “ low carbon ” reduce carbon emission? yes, it is really simple. we often chat about them. but, do you really understand them? have they really taken root on your bottom of heart deeply?
once, the earth mother left our rich energy to cause us to be jubilant, sighed on earth's energy inexhaustible, inexhaustible, now, the newest statistics indicated, the petroleum will dry up after 60 years, the coal also might supply the humanity to use for 250 years; once, developed first, the environment question the situation which neglected is often occurred, now, the sustainable development, was together harmoniously with the nature the biggest difficult to see, the environment question in is taken unceasingly by the people.for all this, the environment question was still stern, the energy conservation reduced the platoon, the low-carbon lives imminently.at the copenhagen climate congress, this affects the human destiny the question slowly to be unable to reach the agreement actually.in the life, is driving the great displacement automobile, purchases including the fluorine air conditioning, the refrigerator, including the phosphorus laundry powder, turns on the air.
conditioning the low temperature also one side to bind in the summer the quilt, the daylight lamp is being long all night clearly, water cock water drop sound day and night not rest these influence environment phenomenon common occurrence.this is rebels with ours position. american president kennedy has said: do not have to ask the country can make any for us, must ask first oneself can make any for the country.the low-carbon life needs everybody to participation!the low-carbon life first is one kind of life manner.so long as wants, each person may be able to achieve! the electricity saving, saves gas and oil, the solar terms, saving water, the tree-planting, makes use of waste, by step generation of vehicle the intravenous drip, in life each aspect, all may choose the low-carbon life the manner.the low-carbon life is also representing one kind healthily, the more natural life style.little eats counter-season food, the generation by works as season food; little uses the disposable product, the generation by the duplicated things; little rides an overhead traveling crane, little sits one time the elevator, the generation rides the bicycle, crawls the staircase, while falls the low-carbon withdrawal, we will have a healthier body and mind.we believed, so long as everybody works as one, participation together, humanity's tomorrow certainly will be able to be happier! schoolmates, today, your low-carbon?

i have the answer to a question that we've all asked. the question is, why is it that the letter x represents the unknown? now i know we learned that in math class, but now it's everywhere in the culture -- the x prize, the x-files, project x, tedx. where'd that come from?
about six years ago i decided that i would learn arabic, which turns out to be a supremely logical language. to write a word or a phrase or a sentence in arabic is like crafting an equation, because every part is extremely precise and carries a lot of information. that's one of the reasons so much of what we've come to think of as western science and mathematics and engineering was really worked out in the first few centuries of the common era by the persians and the arabs and the turks.
this includes the little system in arabic called al-jebra. and al-jebr roughly translates to “the system for reconciling disparate parts.“ al-jebr finally came into english as algebra. one example among many.
the arabic texts containing this mathematical wisdom finally made their way to europe -- which is to say spain -- in the 11th and 12th centuries. and when they arrived there was tremendous interest in translating this wisdom into a european language.
but there were problems. one problem is there are some sounds in arabic that just don't make it through a european voice box without lots of practice. trust me on that one. also, those very sounds tend not to be represented by the characters that are available in european languages.
Dear leaders:
Hello, everyone, I’m Liu Dongdong. I’m a student. There are three people in my family—my father, mother and I.
My father is 40 years old. He is a worker. I think he is a good worker. Because he works very hard. He gets up very early every day and he works for more than 10 hours a day. So he is always busy, he looks very tired when he gets 小学 home. He likes reading newspapers. He usually reads it after supper. So he gets lots of news.
My mother is 38 years old. She is a worker too. She works in a very small factory. She is not tall and she has two big eyes. She loves me and she is good for me. She always buys some books for me. She wants me to be a top student. She also cares for my diet and life.
I’ m 15 years old. I wear glasses. I like reading. I always read books after school. I like singing, too. My favorite singer is Jay Chou. His music is very nice. What do you think of him? I also like making friends. If you want to meet me, please write to me.
Oh, my parents love me and I love them, too. My family is a happy family.
