If Confucius(孔子) were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. He'd need a fan or a strong wind to help him put them out.

While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It's nothing personal. Most Americans don't even remember the birthdays of their own national heroes.

But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.

    In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually include Chinese art, history and philosophy(哲学). Some social scientists suggest that Westerners should take advantage of the ancient Chinese wisdom to make up for the drawbacks(缺点) of Western philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.

So the old thinker's ideas are still alive and well.

    Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.

    As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

    Self-driving vehicles will rely on cameras, sensors and artificial intelligence（AI）to recognize and respond to road and traffic conditions, but sensing is the most effective for objects and movement in the neighborhood of the vehicle. Not everything important in a car's environment will be caught by the vehicle's camera. Another vehicle approaching at high speed on a collision （碰撞）track might not be visible until it's too late. This is why vehicle-to-vehicle communication is undergoing rapid development. Our research shows that cars will need to be able to chat and cooperate on the road, although the technical challenges are considerable.

    Applications for vehicle-to-vehicle communication range from vehicles driving together in a row, to safety messages about nearby emergency vehicles. Vehicles could alert each other to avoid collisions or share notices about passers-by and bicycles.

    From as far as several hundred metres away, vehicles could exchange messages with one another or receive information from roadside units（RSUs）about nearby incidents or dangerous road conditions through 4G network A high level of A1 seems required for such vehicles, not only to self-drive from A to B, but also to react intelligently to messages received. Vehicles will need to plan, reason, strategize and adapt in the light of information received in real time and to carry out cooperative behaviours. For example, a group of autonomous vehicles might avoid a route together because of potential risks, or a vehicle could decide to drop someone off earlier due to messages received, a foreseen crowding ahead.

    Further applications of vehicle-to-vehicle communication are still being researched, including how to perform cooperative behaviour.

    Atlantic puffins（角嘴海雀）are specially used to living on the open sea. Their feathers allow them to stay warm as they float at the ocean's surface or swim underwater. Diving as deep as 60m, they swim by flapping their wings as if flying through the water. There, they hunt herring, capelin, and sand eels.

    Atlantic puffins are also excellent fliers. Flapping their wings at up to 400 beats per minute, puffins can reach speeds of 88km/h.

    April to mid-August is the breeding season for puffins. When a puffin is around three to five years old, it will choose a partner at sea to mate with for life. It is thought that the birds' colourful bills and feet, which fade in the winter and brighten in the spring, help puffins find their potential（可能的）mates.

    Puffins create shelter（庇护所）, about 90cm, in rocky cliffs either in the soil or between rocks. Often, couples will return to the same shelter year after year. At the back of the shelter, they build a nest lined with grasses, seaweed, and feathers. After the female lays a single egg, both parents take turns incubating（孵化）the egg for about 40 days.

    Once the chick hatches, the mother and father will take turns bringing it fish to eat several times a day. Atlantic puffins have the ability to carry several fish in their beaks at one time. The ridges（脊）at the top of their bill hold the fish in place, which allows puffins to keep their mouth open to catch more fish without losing any. In general, they can hold around ten fish in their beak at one time.

    In the wild, puffins can live around 20 years. Their main predator is the great black-backed gull, which can capture a puffin mid-flight or attack a puffin on the ground. Gulls are also a threat because they steal puffins' fish (sometimes right from their mouths), and they pull puffin chicks or eggs from their nests.

    Asia can boast(吹嘘) that it has some of the best beaches in the world. Sihanoukville, Cambodia is a seaside town located 200km or a four­hour bus ride away from the country's capital, Phnom Penh. With several beaches and small offshore islands, it is definitely not a place to miss out if you are intending to visit Angkor Wat, as the beaches there are stunning and still unspoiled by mass tourism.

    Serendipity Beach

    Serendipity Beach is the most popular beach for the masses, since it is the most accessible beach, being the nearest one from the main town area. There are plenty of bars scattered around the beach, so be prepared for the crazy parties every night.

    Ochheuteal Beach

    Ochheuteal Beach is located south of Serendipity Beach, and it's a bit of an improvement from Serendipity Beach itself in terms of the people that go there. Over here, there are bars and pubs, but at night, don't expect wild parties like at the Serendipity Beach area.

    Otres Beach

    All the way down south, near Moat Peam, lies a hidden gem called Otres Beach. This is where you can get your yoga suit on and practice meditation(冥想). This is the quietest beach in Sihanoukville and it is the least crowded, with very few parties. If your idea of a beach holiday is just yourself and the sun, sea and sand, this place is for you.

    Koh Rong

    Koh Rong is an island off Sihanoukville that is covered with beautiful sandy beaches. True relaxation lies at Long Beach, which is located on the other side of the island. Clear water surrounds the beach, and once you get there, you'll be greeted with fine white sand.

    Koh Rong doesn't have any roads, so there are no cars or motorbike rentals — everything is mostly on foot.

    Two strangers came to a village in the evening. They came to the leader of that village and asked for a place to live for the night. The leader said they could stay in the house for strangers. But they were also told about the old custom in the village- people kill the man who snores.(打鼾)

    The two strangers went to the house. They had a good supper there and then they went to sleep. They slept well. One hour passed. Two hours passed. Then one of them began to snore, “Vo, vo, vo…” The other stranger heard the snoring. He thought, “The people will hear the snoring and kill him.” The stranger wanted to save the man. He thought for a while and then began to sing. He sang very well. The people didn't hear the snoring. They listened to the song. Then they began to dance. Some of them sang the song together with the stranger and danced to the music. Men, women and even the leader sang and danced. That entire night one stranger snored, one stranger sang, and all the other people sang and danced.

    In the morning the strangers came to the leader to say goodbye and express their thanks for all he had done. The leader gave them a small bag of money and said, “I give this money to both of you. We had a good time with you. Thank you very much.”

    The strangers left the village. But along the way they began to quarrel. The one who snored wanted more money. He said, “I must have the bigger part. Why did you sing that song last night? Because I snored.” The man who sang had his reason, too. He said that without him the man who snored might have got killed.

    They quarreled and quarreled and couldn't decide on anything. Can you?

    Human began farming around 12,000 years ago, and only in the past 50 years have scientists realized we're not the only species to research into agriculture. A new study has revealed that a small Fijian ant species beat us to becoming the first farmers by almost three millions years.

    The ants have been observed carefully sowing seeds, fertilizing (施肥) them, and waiting for them to grow into plants which bear tasty fruit. What led to the formation of this relationship remains a mystery to scientists. But it puts the ants millions of years ahead of the first human societies to use farming techniques.

    The newly discovered relationship is unique to the animal kingdom. Researchers say they have already watched ants spread seeds, and ants feed plants, but they never had a case where they farm a plant they can't live without. The ants rely on the plants for shelter and food, while the plants need the ants to sow and spread their seeds.

    The find puts the ants millions of years ahead of the first human societies to use farming techniques, who began using agriculture around 12,000 years ago.

    As the plants grow under the care of the ants, the plants to keep further growth. Once the plant is big enough, its hollow chambers provide shelter for the ants. It had previously been spotted that the ants like to live in these small chambers, but the Munich researchers have uncovered the true nature of the relationship that ants sow and take care of the plants to grow themselves a new home.

    The ants will eat the fruit of the plant and harvest their seeds for further projects.

While many other examples of mutually (相互地) beneficial relationships between ants and plants exist, the discovery marks the only case in which both parties other for are totally dependent on each other survival.
