1 . Ever wondered if dogs can learn new words? Yes, say researchers as they have found that talented dogs may have the ability to grasp new words after hearing them only four times.
While previous evidence seems to show that most dogs do not learn words, unless eventually very well trained, a few individuals have shown some extraordinary abilities, according to a study published in the journal Scientific Reports.
“We wanted to know under which conditions the gifted dogs may learn novel words,” said researcher xuekw Claudia Fugazza from the Eötvös Loránd University in Hungary. For the study, the team involved two gifted dogs, Whisky and Vicky Nina. The team exposed the dogs to the new words in two different conditions.
In the exclusion-based task, presented with seven known toys and one new toy, the dogs were able to select the new toy when presented with a new name. Researchers say this proves that dogs can choose by exclusion when faced with a new word, they selected the only toy which did not have a known name.
However, this was not the way they would learn the name of the toy. In fact, when they were presented with one more equally new name to test their ability to recognize the toy by its name, the dogs got totally confused and failed.
The other condition, the social one, where the dogs played with their owners who pronounced the name of the toy while playing with the dog, proved to be the successful way to learn the name of the toy, even after hearing it only 4 times. “The rapid learning that we observed seems to equal children’s ability to learn many new words at a fast rate around the age of 18 months,” Fugazza says. “But we do not know whether the learning mechanisms(机制) behind this learning are the same for humans and dogs. ”
To test whether most dogs would learn words this way, 20 other dogs were tested in the same condition, but none of them showed any evidence of learning the toy names, confirming that the ability to learn words rapidly in the absence of formal training is very rare and is only present in a few gifted dogs.

2 . A recent study showed that the experiences children have in their first few years are important. These experiences affect the development of the brain. When children receive more attention, they often have higher IQs. Babies receive information when they see, hear and feel things, which makes connections between different parts of the brain. There are a hundred trillion connections in the brain o£ a three-year-old child.
Researcher Judit Gervain tested how good newborns are at telling different sound patterns. The researchers produced images o£ the brains of babies as they heard different sound patterns. For example5one order was mu—ba—ba. This is the pattern "A -B— B”. Another order was mu—ba—ge. This is the pattern "A-B—C”. The images showed that the part of the brain responsible for speech was more active during the "A—B-B” pattern. This shows that babies can tell the difference between different patterns. They also were sensitive（敏感）to where it occurred in the order.
Gervain is excited by these findings because the order of sounds is the base of words and grammar, "Position is key to language," she says. "If something is at the beginning or at the end, it makes a big difference： 'John caught the bear' is very different from 'The bear caught John.
Researchers led by scientist Patricia Kuhl have found that language delivered by televisions, audio books, the Internet, or smartphones——no matter how educational—— doesn't appear to be enough for children's brain development. They carried out a study of nine-month-old American babies. They expected the first group who'd watched videos in Chinese to show the same kind of learning as the second group who were brought face-to- face with the same sounds. Instead they found a huge difference. The babies in the second group were able to distinguish （辨别）between similar Chinese sounds as well as native listeners. But the other babies-regardless of whether they had watched the video or listened to the audio-learned nothing.

3 . Every week in China, millions of people will sit in front of their TVs watching teenagers compete for the title Character Hero, which is a Chinese-style spelling bee. In this challenge, young competitors must write Chinese characters by hand. To prepare for the competition, the competitors usually spend months studying dictionaries.
Perhaps the show’s popularity should not be a surprise. Along with gunpowder and paper, many Chinese people consider the creation of Chinese calligraphy(书法) to be one of their primary contributions to civilization. Unfortunately, all over the country, Chinese people are forgetting how to write their own language without computerized help. Software on smart phones and computers allows users to type in the basic sound of the word using the Latin alphabet. The correct character is chosen from a list. The result? It’s possible to recognize characters without remembering how to write them.
But there’s still hope for the paint brush. China’s Education Ministry wants children to spend more time learning how to write.
In one Beijing primary school we visited, students practice calligraphy every day inside a specially decorated classroom with traditional Chinese paintings hanging on the walls. Soft music plays as a group of six-year-olds dip brush pens into black ink. They look up at the blackboard often to study their teacher’s examples before carefully attempting to reproduce those characters on thin rice paper. “If adults can survive without using handwriting, why bother to teach it now?” we ask the calligraphy teacher, Shen Bin. “The ability to write characters is part of Chinese tradition and culture,” she reasons. “Students must learn now so they don’t forget when they grow up.” says the teacher.

4 . The Forbidden City
The Forbidden City in Beijing, China, was completed in 1420 during the early Ming Dynasty. It is the largest ancient palatial （宫殿似的） building in the world and it’s open to tourists to allow them to have a look at ancient Chinese architecture.
The Little Mermaid
The Little Mermaid is a statue in Copenhagen, Denmark. It sits on a rock in the harbor. It was inspired by a performance of a ballet based on the fairy tale The Little Mermaid by Hans Christian Andersen. It was presented to the public on 23 August, 1913. And there are many tourists taking photos with the Little Mermaid every year.
The Taj Mahal
As one of the Seven Wonders of the World, the Taj Mahal is the jewel of India. It is considered as the finest example of Mughal architecture, a mix of Indian, Persian and Islamic styles.

5 . If you don't use it, you lose it. At least, that's how the old saying goes. It refers to the idea that something which does not get used regularly quickly falls into a state of decline. Muscles, for example, will waste away without use. In order to resist this, people take regular exercise to keep their skills sharp.
Well, what about the brain? As we age, our brains can naturally begin to decline. In some cases, this can lead to certain mental conditions such as dementia(痴呆)，which I'm sure you will agree, no one wants. However, all is not lost because these days it's relatively easy to train your brain. Smart phones and apps have put programmes into our hands that can test, maintain and even improve our memories, mathematical skills and a lot of other mental abilities. With a little practice every day, we can keep our brains nice and sharp, right?
Well, no, actually. According to a report from the Global Council on Brain Health, even though many people thought it was important to play online games, such as puzzles and mind games, which are designed to improve brain health, the evidence of the benefits was “weak to non-existent”.
There are other ways to promote the old grey matter. It recommends seeking out new activities that challenge the way you think and are socially engaging，while leading to a healthy lifestyle. Among their suggestions are practising tai chi, taking photography classes, learning new technologies, gardening, art projects or volunteering.
There's more good news, too, James Goodwin, chief scientist at Age UK has said that brain decline is not inevitable (不可避免的）. As long as the activities are “new to you and require your concentrated attention”, they can provide benefits for brain health. So, hurry up, get out there and try something new. Maybe it's time to try that hobby you've always wanted to do. And as for me? I'm off to learn the piano.

6 . When her classmates were having a good time, Molly sat at the picnic table alone. She remained embarrassed around her classmates. She seemed unsure of what to do or say, yet I could see her eyes longing for acceptance. Many students had already decided that her friendship would not be worth（值）the energy required to overcome the embarrassment. Others laughed at her. Most ignored her—except for one.
Brianna was making the other students laugh, as usual. “Brianna, do you see Molly down there? Would you mind walking down there and inviting her to come up here with the rest of us? I said.
Brianna sighed. I could tell she didn’t want to waste her precious time to do what I was asking of her, but I also knew her heart. She often thought of others before herself—a rare character for anyone, much less a kid.
Knowing this choice was hard for her, I pulled out a D-buck, our class currency（货币）. Though this was not the ideal way to deal with this situation. I needed her cooperation（合作）. “Here, I’ll pay you for your time.” I said to her. She offered an insincere smile, grasped the green paper, and headed down the hill.
As the rest of the children screamed and laughed, my eyes locked on Brianna as she neared the picnic table. Molly could be difficult to get along with, and I wouldn’t have been surprised if she sent Brianna back alone, refusing her invitation. When she encouraged herself to a standing position, I sighed with relief.
Minutes later, I felt a tap on my shoulder. “Here. Mrs. D.” Brianna handed me the D-buck. “Why?” I asked. “I shouldn’t keep this.” Her eyes fell to her feet, guilt showing from her quiet voice. “I don’t want Molly to think I only went to get her so I could earn the money. She’s my friend.”
A moment later, they were all laughing again, and who should I see among them, laughing for the first time that week? Molly.

The WWF recently released its 10th Flagship Living Planet Report. The group warns the condition of the world's animals is worse than its earlier reports showed, indicating worldwide action is needed.
The WWF is worried about the loss of and damage to Earth’s environment. The report provides information about more than 10,000 animal populations from 1970 to 2010. These populations are called “vertebrate species,” or animals with backbones — like fish, birds, mammals, amphibians and reptiles. The report shows these populations have dropped by 52 percent in just 40 years. It warns freshwater species have fallen by 76 percent, which is almost twice the loss of land and ocean species. Most of these losses are in the tropics, with the biggest drop in Latin America.
Marco Lambertini, the WWF’s International Director-General said, “This is about losing natural habitats. This is about converting forests, grasslands, and wetlands into agriculture mainly, and it is about unsustainable use of wildlife. Illegal hunting has been actually increasing over the last 10 years, which definitely a driving force for extinction, particularly of large species.”
The report also notes what it calls the world’s “Ecological Footprint”, that is, the effect of human activities on the planet. Mr. Lambertini says there has been an increase in carbon dioxide gases and the pouring of nitrogen into oceans and rivers from fertilizers used in agriculture, which certainly cannot continue.
“We are consuming on average every year about the equivalent of about 1.5, one and a half times the resources available to the planet. That means we are cutting trees more quickly than they can be restored. We are fishing the oceans more quickly than fishing stocks can reproduce, and we are emitting in the atmosphere more CO2 than the natural systems can actually absorb, which is clearly not sustainable.”
Mr. Lambertini warns climate change affects almost everyone on the planet and that whole species may disappear if the world does not reduce the effects of humans on the climate.
