Getting rid of dirt, in the opinion of most people, is a good thing. However, the attitudes to dirt are always changing.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, and washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. The king of England did something similar in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. France’s Henry IV was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief above was long-lived, dirt has no longer been regarded as a nice neighbour ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War II. Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家) , encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.

Scientists have solved a puzzle about modern humans, after research showed that a famous skull of a human ancestor found in South Africa is a million years older than experts thought. This discovery has changed what we know of human history.
The skull, which scientists have named “Mrs Ples”, is from an ape-like human relative from a species called Australopithecus africanus (南方古猿). It was found near Johannesburg in 1947 and, based on evidence from its surroundings, was thought to be between 2. 1 and 2. 6 million years old. This puzzled scientists, because although Mrs Ples looks like a possible early ancestor of early humans, the first true humans had already evolved by the time she apparently lived. For this reason, scientists had decided that Australopithecus afarensis, a similar species from East Africa that lived about 3.5 million years ago, was our most likely ancestor instead.
To get a more accurate age for Mrs Ples, a team led by Professor Darryl Granger of Purdue University in Indiana, US, used a new method to date the sandy rocks where the skull lay. They measured the amount of certain chemicals in rocks, which form at a steady rate when they are exposed to cosmic rays (宇宙射线) on Earth’s surface. Once rocks are buried, these chemicals stop forming and slowly disappear;the surviving amount reveals how much time has passed since the rock (or bones) were on the surface.
The new study shows that Mrs Ples and other australopithecine bones nearby are between 3.4 and 3.7 million years old. This means they lived at the same time as their East African relatives, so that either group could have given rise to modern humans. However, team member Dr Laurent Bruxelles pointed out that over millions of years, at only 2,500 miles away, these groups had plenty of time to travel and to breed with each other. In other words, the groups could quite easily have met, had children together and both been part of the history of modern humans.

4 . We think of history as a time line — a series of events stretching thousands of years into the past. It’s time to think bigger. Instead of a line, imagine a web of endless connections interacting over billions of years, linked together to create everything we’ve ever known. From the clothes we wear to the rise and fall of empires (帝国) to the revolution of language, it’s the horse that links them all.
6, 000 years ago, the early people in central Asia spoke an ancient language known as “Proto-Indo-European.” Their words would eventually spread, change and develop, branching into French, Italian, Spanish, Greek Russian, Hindi, German, and English, giving us the languages spoken by nearly half the world. The reason is that these are the first people on earth to ride horses, which creates highway for their words.
2, 000 years ago, Romans traditionally wore tunics, but it’s hard to ride a horse in clothes like this. As Romans moved north to conquer the barbarians (野蛮人), they noticed their enemies wore something different into battle: pants. Pants are warmer and a lot more comfortable to wear on horsebacks The Roman army made the switch and soon so did men everywhere. Horses are a key reason why millions of people around the world wear pants.
For 6, 000 years, horses have been the primary way of conquering, making large empires possible. Horses helped Rome expand from Britain to North Africa. But why didn’t these enormous ancient empires grow even bigger? The evidence suggests a surprising theory that ancient empires have a size limit determined by the horse. If the borders of an empire are more than 14 days’ ride from the capital, it becomes a struggle to continue control. Speed of communications is essential for an empire. You must be able to get messages to and from the border within a reasonable time. If you can’t do that, you can’t respond to attacks.
On the scale of big history, it’s hard to think of any other mammal that’s had such an influence on human history as the horse.

5 . A fresh and gentle wind on your face, soft sand under your feet and blue waters as far as the eye can see. Is there any other Olympic sport that is played in such pleasant conditions as beach volleyball？
“I’ve gone to a lot of beautiful places, and met a lot of beautiful people. That wouldn’t have happened if I had been playing another sport.” said Randy Stoklos, America’s most famous beach volleyball player.
The sport began as a four-a-side game on beaches in Southern California in the 1920s. The first recorded two-man game took place there in 1930, and the first tournament (锦标赛) was held in Los Angeles 18 years later. The winners were awarded a case of Pepsi. In the 1950s, women started playing and the sport soon spread to Europe and South America. Yet at that time, beach volleyball was more an entertainment show than a sport, with beauty contests included. The Association of Volleyball Professionals was founded in 1983 and beach volleyball developed into a fast, athletic sport. Its world-wide popularity won beach volleyball a place at the 1996 Olympics in Atalanta, where 24 male teams and 16 female teams took part. At present, the US and Brazil are the best in the world at beach volleyball.
The game came to China in the early 1990s and there have been national tournaments since 1994. It became an official event at the Eighth National Games in 1997. China’s You Wenhui and Wang Lu finished ninth in the women’s beach volleyball world championships in Brazil.

8 . Ancient Chinese folk paintings and many other art styles have been passed down from generation to generation, and are still practiced in different parts of China. Here's a look at four unique Chinese folk-art forms.
Chinese Opera is the traditional form of Chinese drama. According to incomplete statistics, in China's various ethnic regions there are about more than 360 kinds of operas. The most famous ones include Peking Opera, Kunqu Opera, Yueju Opera, Yuju Opera, Sichuan Opera, Fujian Opera, Hebei opera, Huangmei Opera arid so on, in total more than 50, among which Peking Opera is the most popular in China.
Shadow Play (皮影戏) dates back to Western Han Dynasty in Shaanxi more than 1,000 years ago. The moving figures, usually carved out from leather, are operated by folk artists, accompanied by music and singing. It is the world's first dubbed (配音的) motion picture art form, thus considered the “ancestor” of modern film. Today this art form is still popular in northern China.
Paper-cutting is one of the most popular traditional decorative arts in China with a long history. Paper-cutting can be seen across China and it has even developed into different local genres (流派). They are usually used to decorate gates and windows during festivals.
The Kite was invented by Chinese people. According to legend the earliest kite in China was a wooden bird by Mo Di in the Eastern Zhou Dynasty. Later his student Lu Ban improved the tech and used bamboo as material to make a kite. Today, various kite-flying activities can be found in different regions of China. Shandong Weifang Kite Festival is held every year and attracts lots of kite lovers and travelers.

10 . Until recently, several lines of evidence — from fossils genetics, and archaeology — suggested that humans first moved from Africa into Eurasia (the land of Europe and Asia) about 60,000 years ago, quickly replacing other early human species, such as Neanderthals and Denisovans, that they may have met along the way.
However, a series of recent discoveries, including 100,000-year-old human teeth found in a cave in China, have clouded this straightforward statement. And the latest find, a prehistoric jawbone at the Misliya Cave in Israel dating back to nearly 200,000 years ago, which is almost twice as old as any Homo sapiens (智人) remains discovered outside Africa, where our species was thought to have originated from, has added new and unexpected twist.
The find suggests that there were multiple waves of migration across Europe and Asia and could also mean that modern humans in the Middle East were interacting, and possibly mating, with other human species for tens of thousands of years. “Misliya breaks the mould (模式) of existing assumptions of the timing of the first known Homo sapiens in these regions,” said Chris Stringer, head of human origins at the Natural History Museum in London. “It’s important in removing long-lasting-constraint (限制) on our thinking.”
Prof. Hershkovitz, who led the work at Tel Aviv University said, “What Misliya tells us is that modern humans left Africa not 100,000 years ago, but 200,000 years ago. This is revolution in the way we understand the evolution of our own species.” He also added that the record now indicates that humans probably travelled beyond the African continent whenever the climate allowed it. “I don’t believe there was one big departure from Africa,” he said. “I think that throughout hundreds of thousands of years humans were coming in and out of Africa all the time.”
The discovery means that modern humans were potentially meeting and interacting during a longer period with other ancient human groups, providing more opportunity for cultural and biological exchanges. It also raises interesting questions about the fate of the earliest modern human pioneers. Genetic data from modern-day populations around the world strongly suggest that everyone outside Africa can trace their ancestors back to a group that left around 60,000 years ago. So, the inhabitants of the Misliya Cave are probably not the ancestors of anyone alive today, and scientists can only guess why their branch of the family tree came to an end.
