1 . J.K. Rowling frequently shows there is magic every day. Her Harry Potter series has helped people through times of stress and depression and she is always there to deliver wise words of encouragement.

She is one celebrity who is very active on Twitter. So when a single dad named Matt Burke sent her a message thanking her for the series, she noticed. Her series had helped strengthen his relationship with his 9-year-old daughter Bailey.

He included a link to his article titled Being a Broke Parent. He explained how he hadn’t found a level of financial stability that allowed him to pay bills on time and take his daughter on more activities and events. The family also doesn’t have the Internet or TV, which means there’s no “digital babysitter”, and he has to rely on his own creative ways to bond with his daughter. Since he received the series, the main thing that has occupied them these days is reading books together.

Burke admits that he thought he was “too cool” for the books when they first came out and he was in his twenties, but he’s loving reading them now. “We switch off chapter by chapter reading them out loud,” Burke explains. “This not only allows her to get more used to reading aloud in front of someone, but it gets me directly involved in something she loves, and it gives me the chance to be very dramatic when I read my chapters and bring myself into the characters in the book, which has proven to be a ton of fun.”

After hearing Burke’s story, Rowling said how honored she was when Harry Potter was a part of his family’s life and offered Burke more signed books. Besides, people are also offering to send Burke more books as gifts. For Burke, this experience, far more than gifts, will be what he treasures.

6 . Wouldn’t it be wonderful to travel to a foreign country without having to worry about the headache of communicating in a different language?

In a recent Wall Street Journal article, technology policy expert Alec Ross argued that, within ten years or so, we would be able to communicate with one another through small earpieces with built-in microphones. That’s because technological progress is extremely fast. It’s only a matter of time. Such is the belief among certain parents that the technology is imminent and they’re wondering if their kids should learn a second language.

It’s true that an increase in the quantity and accuracy of the data loaded into computers will make them cleverer at translating “Noes Bueno dormer mucho” into “It’s not good to sleep too much”. Replacing a word with its equivalent (对等词) in the target language is actually the easy part of a translator’s job. But even this seems to be a difficult job for computers.

It’s so hard for computers because translation doesn’t — or shouldn’t — involve simply translating words, sentences or paragraphs. Rather, it’s about translating meaning. And in order to infer meaning from a specific expression, people need to understand a lot of information all at once. Think about all the related clues that help us understand what someone is trying to say: volume, gesture, situations, and even your culture. All are likely to convey as much meaning as the words you use.

Therefore, we should doubt a machine that can’t understand our world like we do. If people from different cultures can upset each other without realizing it, how can we expect a machine to do better? Unless engineers actually find a way to breathe a soul into a computer, undoubtedly when it comes to conveying and interpreting meaning using a natural language, a machine will never fully take our place.

7 . Is It Worth Buying Organic Food?

Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.

The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”

For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.

While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.

Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

8 . Life will probably be very different in 2050. First of all, it seems that TV channels will have vanished by 2050. Instead, people will choose a programme from a “menu” and a computer will send the programme directly to the television. By 2050, music, films, programmes, newspapers and books will come to us in the similar way.

In many places, agriculture is developing quickly and people are growing fruit and vegetables for export. This uses a lot of water. Therefore, there could be serious shortages of water. Some scientist predict that water could be the cause of wars if we don’t act now.

In the future, cars will run on new, clean fuels (燃料) and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Also, by 2050, space planes will fly people from Los Angeles to Tokyo in just two hours.

Some big companies now prefer to use robots that do not ask for pay rises or go on strike, and work 24 hours a day. They are also easy to control. And they never argue with people. They can be easily used in a variety of places — factories, schools, offices, hospitals, shops and homes.

Scientists will have discovered how to control genes (基因). Scientists have already produced clones (克隆) of animals. By 2050, scientists will be able to produce clones of people and decide how they look and how they behave. Scientists will be able to do these things, but should they?

9 . In habitats across the planet, animals periodically drop everything to walk, fly or swim to a new place. Some animals such as whales and geese learn migration paths by following their parents. Others, including small songbirds, gain the distance and direction of their migration within their genetic code. And some animals use a combination of genetics and culture to guide their migration.

Another group of migrators does not quite fit either model, and researchers have only recently started to figure out how they find their way. The Cory’s shearwater is an oceangoing seabird that migrates over the Atlantic every year. The young do not migrate with their parents, so culture cannot explain their journeys. And the exact paths vary wildly from individual to individual, making genetics equally unlikely.

Cory’s shearwaters are long-lived, rarely producing young successfully before age nine. This leaves an opening for learning and practice to develop their migration patterns. Researchers call this the “exploration-refinement”, and until now it has been hypothetical (假设的) because of difficulties in tracking migratory animals’ movements.

But a team of researchers has done that by attaching small geolocators to more than 150 of the birds aged four to nine. They found that younger birds traveled longer distances, for longer periods, and had more diverse paths than older birds. “We finally have evidence of the ‘exploration-refinement’ for migratory birds,” says Letizia Campioni, who led the study. Younger Cory’s shearwaters are able to fly just as fast as the adults——but they do not, suggesting that the young do more exploring, which gradually fades as they mature and settle into a preferred course.

“Although it may seem less efficient than other strategies, exploration refinement could be beneficial to birds and other organisms in a rapidly changing world due to unpredictable man-made changes,” says Barbara Frei. “It might be safer to repeat a behavior that was recently successful than to rely on patterns that were perfected long ago but might no longer be safe.”

10 . Foreign visitors to the UK might be disappointed when they learn that not everyone there speaks like Harry Potter and his friends. Usually, there’s an assumption by many non-Brits that everyone in Britain speaks with what’s known as a Received Pronunciation (RP，标准发音) accent, also called “the Queen’s English”. However, while many people do talk this way, most Britons speak in their own regional accents (口音).

Scouse, Glaswegian and Black Country — from Liverpool, Glasgow and the West Midlands — are just three of the countless non-RP accents that British people speak with. There are even differences in accents between towns or cities just 30 kilometers apart. What is even more disappointing is that not speaking in a RP accent may mean a British person is judged and even treated differently in their everyday life.

In a 2015 study by The University of South Wales, videos of people reading a passage in three different UK accents were shown to a second group of people. The group then rated how intelligent they thought the readers sounded. The lowestrated accent was Brummie, native to people from Birmingham, a city whose accent is considered working class.

However, there is no need to be disappointed though you are not speaking in a RP accent. In fact, doing the opposite may even give you strength.

Kong Seongjae, 25, is an Internet celebrity from Seoul. After studying in the UK, he picked up several regional accents. He’s now famous for his online videos, where he shows off the various accents he’s learned. “British people usually get really excited when I use some of their local dialect words, and they become much friendlier. I think it makes a bit of bond between local people and foreigners to speak in their local accent,” he said.

So if you’re working on perfecting your British accent, try to speak like someone from Liverpool, Glasgow or Birmingham. You may not sound like Harry Potter, but you are likely to make more friends.
