Once upon a time, there was an old farmer who planted a plot of rice. After he planted the seedlings, every day he went to the field to watch the seedlings grow. He saw the young shoots break through the soil and grow taller each day, but still, he thought they were growing too slowly. Eventually he got impatient with the young plants and suddenly he hit upon an idea that one by one, he pulled up the young plants by half an inch. The next early morning, the young man couldn\u2019t wait to check his \u201cachievement\u201d, but he was heart-broken to see all the pulled-up young plants dying.

Once upon a time, there was a man who wanted to steal his neighbor\u2019s doorbell. However, he knew clearly that the bell would ring and catch the other people\u2019s attention as long as he touched the bell. So he thought hard and suddenly hit on a clever \u201cidea\u201d. He plugged his ears with something, thinking that everything would go well when he stole the bell. Unfortunately to his disappointment, the bell still rang loudly and he was caught on the spot as a thief.

The Fox and the Crow \u201c\u72d0\u72f8\u548c\u4e4c\u9e26\u201d
One day a crow stood on a branch near his nest and felt very happy with the meat in his mouth. At that time, a fox saw the crow with the meat, so he swallowed and eagerly thought of a plan to get the meat. However, whatever the fox said to the crow, the crow just kept silent. Until the fox thought highly of the crow\u2019s beautiful voice, the crow felt flattered and opened his mouth to sing. As soon as the meat fell down to the ground, the fox took the meat and went into his hole.

Draw a Snake and Add Feet to It \u201c\u753b\u86c7\u6dfb\u8db3\u201d
Long long ago, several people had a jar of wine among them and all of them wanted to drink it by himself. So they set a rule that every one would draw a snake on the ground and the man who finished first would have the wine. One man finished his snake very soon and he was about to drink the wine when he saw the others were still busy drawing, so he decided to draw the feet to the snake. However, before he could finish the feet, another man finished and grabbed the jar from him, saying, "Who has ever seen a snake with feet?\u201d The story of "Draw a snake and add feet to It.\u201d tells us going too far is as bad as not going far enough.

Our water poloSomeone says, our earth should be called water polo. This makes some sense, because we live in this planet with water, and 71% of the surface area occupied by water. The astronaut, the earth is a blue ball, very bright, the sun family of the one and only. The earth's water is very great, a total volume of 1386000000 cubic km. Among them, 96.5% in the ocean; 1.76% in glaciers, permafrost, snow cover, is a solid state; 1.7% in the ground; the remaining, lakes, rivers, dispersed in the atmosphere and organisms. So we can say, from heaven to earth, from land to ocean, water everywhere in the world.Shaking heaven and earth 's water cycle, all the water in the world is a linked system. Sea water in the sunlight irradiation, continuous evaporation, water vapor to diffuse in the ocean; a portion of the vapor is airflow to freeze over land, it condenses into small droplets, into the cloud, and falls to the ground is rain or snow; snow water landing, some flow into the pit, or into the ground, some into the minor groove, sinks into the river, to the sea. Numerous small water drops is kept in the world tourism. Water cycle to ensure human fresh water supply. Know the circulation of water, and you can explain: cloud's hometown in where? Why is a river in day and night is always the stream never stops flowing.? Why thousands of years, so many rivers flow into the ocean, but the ocean not overflow?Fresh water where the water on the earth, although large quantities, and can directly use it in production and life, and has a small. First of all, sea salt and bitter, not drinking, not pouring in, it will be difficult for the industry. Secondly, freshwater total consumption 2.6% the left and right sides, most of them ( 99%), frozen in away from human two north-south and permafrost, cannot use, less than 1% of fresh water, they are scattered in the lakes, rivers and under the ground. And the whole world total water volume as a drop in the bucket compared, fresh water
Does Technology Reduce Social Isolation?Hundreds of daily updates come from friends on Facebook and Twitter, but do people actually feel closer to each other?
每天在Facebook和Twitter上都有朋友们数以百计的更新，但实际生活中人们是否感觉彼此更亲近呢？
It turns out the size of the average American’s social circle is smaller today than 20 years ago, as measured by the number of self-reported confidants in a person’s life. Yet contrary to popular opinion, use of cellphones and the Internet is not to blame, according to a new study released Wednesday by the Pew Internet and American Life Project.
根据互联网与美国生活专案周三发布的一项最新调查，在计算过美国人日常生活中自己认为的密友知己的数量后，事实证明当代美国人社交圈子的平均人数比他们20年前要小。但是与当前流行的观点所不同的是，这并不归罪于手机的使用和网络的普及。
In fact, people who regularly use digital technologies are more social than the average American and more likely to visit parks and cafes, or volunteer for local organizations, according to the study, which was based on telephone interviews with a national sample of 2,512 adults living in the continental United States.
根据一项调查表明，事实上经常使用数字技术的人比普通的美国人更具社交性，而且也更多的游览公园，光顾咖啡馆或更多的参加当地的志愿者活动。该项调查通过电话采访了美国本土大陆的2512名成年人。
The study found some less-than-social behavior, however. People who use social networks like Facebook or Linkedin are 30 percent less likely to know their neighbors and 26 percent less likely to provide them companionship.
这项调查也发现了一些不太符合社交性的习惯的行为，那就是，经常使用社交网站Facebook和Linkedin的人不太喜欢去认识他们的邻居，有26%的不喜欢和邻居交往。
The circle of close friends for mobile phone users tends to be 12 percent larger than for nonusers. People who share online photos or instant messages have 9 percent larger social circles than nonusers.
经常使用手机的人，他们的好朋友圈子比不使用手机者常常要多12%，在网上分享自己的照片和及时信息的人，他们的好朋友圈子比不使用者常常要多9%.
The study also found that people still prefer face-to-face communication as the primary means to stay in touch with friends and family (people see loved ones in person an average of 210 days a year). Respondents said that they were in touch via mobile phone an average of 195 days a year.
这项调查也发现人们更喜欢面对面的沟通，这是他们和好友和家庭成员保持联系的最重要的方式(人们一年中有210天会亲自看自己的亲人)。被调查者说他们一年中平均有195天通过手机和他们联系。
"Medicine" Build Overall Planning
"Medicine" Build Overall Planning
It is important physical foundation that drugs could keep and promote the human health, improve living quantity and prolong the mean life of the human. Medicinal industry is a high input, high output promising industry with vast market foreground. Continuously advancement of the ab
ility of research and development, production capacity and the technical level, not only ensure the human health, but also is significant for the adjustment and optimization industrial structure, the development of district economy.
For its special property and position, medicinal industry is always concerned. With the progress of biological technique and continuously increment of live standard, it endows the medicinal industry with the vitality. The emergences of medicine valley, medicine harbor, Medicine City and mus ltinational medicine group in China and overseas, indicate that worldwide medicinal industry have become the most competitive industrial evaluative realm nowadays. All the cities and districts, regarding medicine industry as predominate industry, face unprecedented opportunity and challenge. The Shijiazhuang district is production base of traditional Chinese medicinal materials, and also is one of the quickest cities in medicinal industry after the reformation and open. After development of five decades, Shijiazhuang had become the city of the medicinal industry mainly with chemistry raw material medicine production. Facing against the pressure of competition, for the Shijiazhuang transition from the large mus nicipal to the mighty mus nicipal, further setting the pace for the mus nicipal medicinal feature and consolidation and elevation the status of Shijiazhuang in China and overseas, we especially made a general construction planning of Medicinal City in Shijiazhuang according to the national industrial policy, economic function location of Shijiazhuang made by State Department and physical situation of mus nicipal medicinal industry development.
1、Construction basis of Medicinal City
1）Developments background of Medicinal City
International background
Since 1975, worldwide medicine industry disengaged from the traditional industry cling to chemical industry already became a sturdy industry system and a support of the world economy. According to statistic, the sale income of worldwide drugs come to US$368 billion in 2000. Medicinal industry will keep the high-speed development in 21 century, the sale volume will reach US$ 540 billion in 2005 and will up to US$ 800 billion.
The gravity center of drug and biological pharmacy industry of current world primarily locate in the developed region and nation, such as Japans, United States, Europe, and formed some mus ltinational medicine industry groups with the global influence in the competition, The sale income of three greatest mus ltinational medicine groups, Huirui, Grance-Slick and Mock, all exceed US$20 billion. Through the development and differentiation of more than 20 years, the configuration pattern of global medical care resource had formed, the trend will be certain that medicine origin in chemical raw material would be transferred from developed nation to developing nation, and Chinese drugs internationalize.

What 10 years of Apple did to its main product
What 10 years of Apple did to its main product？
By Matt Tinsley, Sep 24th 2010
How time flies! In the year 2000, I was just finishing high school, listening to Bush, and becoming acquainted with Windows 2000. Back then, I knew very little about Apple, and I'd certainly not heard of the Bondi Bubble iMac (the first iMac was released in 1998). In 2010, well...how things have changed for me!
And, as illustrated by Brett Jordan in the graphic above, things have also changed at Apple.
It's incredible to think that the iPhone has taken center stage at Apple over the last three years. As noted by some of our commentators, there has been a real lack of Mac-centric news recently. Sure, there was the update to the iMac a few months ago, but it's glaringly obvious that the Mac has taken a back seat to the iPhone -- certainly in the limelight department. In fact, I'm reveling in the fact that I'm writing about the iPhone and the iMac at the same time!
Today, the Mac is the center of our digital hub, but it's no longer the center of our digital world. When we leave the house / office / room where the Mac lives, it's the iPhone ( iPad / iPod touch) that is constantly in our hands, and Apple knows it!
Of course, we have to come back to our Macs eventually (in my case, repeatedly, everyday) because the iPhone can't do everything that we want it to, or even some of the things that we want done well, yet. But just looking at this picture shows how far things have come, and how the direction taken by personal computing is becoming even more personal.
The only feature of the iPhone 4 that doesn't beat the iMac of yesteryear is screen real estate. The processor and RAM are double the capacity of the iMac, the iPhone's storage is 2 gigabytes larger, and it's flash-based memory. And of course, it's tiny in comparison. As noted by Obama Pacman, it's Moore's law in effect.
But when will it end? In 10 years time, will we have an iPhone that's five times smaller than the current one, but more powerful than the personal computers of today? Who knows? That might be a weird phone, but anything could happen. For now, I'm still stuck with my iPhone 3G, and I think it might still have some Bush on it. In the meantime, I'm just looking forward to getting the iPhone 4!
