City Life in Thailand is much like city life in the United States. People live in tall buildings or in houses close together. But outside the cities, life is different. People usually live on farms far apart from one another. They grow their own food or buy fresh food almost every day at the market. But the market is not in a building. It is a floating market located on a river.

    Lamai and her family live on a farm. They grow fruits and vegetables and sell them at the market each day. Long before the sun comes up, Lamai and her brother help their parents. They pick out fruits and vegetables and clean them. Then they load everything into a long boat.

    Their boat is ready by about 6:00 a.m. Lamai and her mother row to the closest floating market. On the way the water is still and peaceful. Lamai sees the bright sun beginning to shine.

    Soon Lamai hears laughing and yelling in the distance. Her mother rows the boat around a corner. Suddenly they are at the floating market. Hundreds of boats are gathered at a wide place in the river. Lamai's mother is selling bananas and ripe tomatoes today. For Lamai a trip to the market is more than just a chance to sell or buy something. It is a chance for her to talk to her friends.

    Today Lamai sees her friend Suki. He is helping his mother prepare meals in their boat. Lamai loves the smell of the fried bananas Suki's mother is making. Lamai's mother rows over to buy a late breakfast. As Lamai eats, she and Suki talk about their summer plans.

    At around 11:00 a.m. people begin to go home. She is sleepy from waking up so early. Her mother has sold most of what they brought to the market. The will leave the market with less food in their boat but with more money for Lamai's family.

    Nowadays science has made great progress in every aspect and more and more really good inventions have changed our daily lives. However, the U.S. Patent Office has issued over 7.5 million patents (专利), and not all of them are quite so celebrated. Some good, some bad, and some crazy! The following lists some of the most unusual ideas that have come along.

    Snake Leash (皮带)

    In 2002, a patent was issued for a snake-walking leash. There are at least two major problems with this idea. 1) Dog leashes fit securely between the head and shoulders. A snake does not have shoulders; so it might slither (蜿蜒滑行) away. 2) Dogs are OK for public places because they are social animals, and people like them. Snakes are not OK for public places because they are not social, and some people are terrified of them.

    Stadium Helmet

    Americans are known for their love of sports. Unfortunately, good tickets to games are expensive, so some fans have to sit in the backward sections. This invention, patented in 2000, is designed for these fans. Featuring a built-in radio, binoculars (望远镜), a cooling fan, and a helmet for falling litter, this design transforms the stadium experience.

    Bacon Alarm Clock

    When you think about it, waking to the dreadful, blaring noise of an alarm clock is a terrible way to start the day. However, this clock could change that. You simply put a piece of frozen bacon in the alarm clock, set the alarm, and go to sleep. The clock gently wakes you up with the mouth watering smell of bacon the next morning, just like waking up on a Sunday morning to the smell of mom cooking breakfast. Who said there's no time to eat breakfast?

    Toilet Lock

    In 1969, a patent was issued for a really bad idea the toilet seat lock. First of all, fishing for your keys when you have to go seems very unpleasant. Then there is the possibility of losing the key altogether. What about guests? Just think that you would have to ask permission for the bathroom. Of course, there is the ultimate question: Why would you lock it in the first place?

    On average, Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk, Strayer explained that all this time spent with technology is making our brains tired.

    Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain, which, Strayer explains, is important for critical thinking, problem-solving and decision-making.

    So it is important to give the brain a rest. And being in nature, Strayer claims, helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore, swim, sleep, eat and play. Camping may be just what a tired brain needs.

    Take Carl for example. He lives in West Virginia and enjoys camping. He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children. She calls it a "regenerative" experience.

    At the University of Utah, David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However, he found it is the long-term contact with nature that does the most good. He and his research team found spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.

    One of the best-loved American writers was William Sydney Porter, or O. Henry. From 1893 he lived with his family in a house in Austin, Texas, which is now a museum. Visitors to Austin can see the house. It was saved from destruction (破坏) and turned into a museum in 1934. The museum is a good way to learn about the interesting life of the American writer.

    William Porter rented this house in Austin and lived there with his wife Athol and daughter Margaret for about two years. Many objects in the museum came from the Porters. Others did not. An important piece in the room is the original photo over here. It was taken there in the house about 1895. The piano there dates back to the 1860s. His wife took lessons on it when she first moved to Austin.

    Porter wasn't a successful writer in the beginning. He worked on a farm, in a land office and bank. He also loved words and writing. The museum has a special proof (证明) of Porter's love of language—his dictionary. It is said that he had read every word in that dictionary.

    Later William Porter was forced to leave Austin because he was charged (指控) with wrongdoing at the bank and lost his job. Because he was afraid of a trial (审判), he left the country secretly. But he returned because his wife was dying. After her death, he faced the trial and served three and a half years in a prison in Ohio.

    William Porter would keep his time in prison a secret. But there was one good thing about it. It provided him with time to write. By the time he was freed, he had published 14 stories and became well-known as O. Henry. Porter later moved to New York City and found great success there. He published over 180 stories in the last eight years of his life.

Most children love stories. Stories are entertaining and fun, but can they be more than just fun? Findings from a new study led by Rebecca de Leeuw, an assistant professor at the Radboud University, indicate stories in movies can also be meaningful for children. 

The researchers contacted children between 4 and 15years old after they watched the Disney film Inside Out. This film takes place mainly in the head of an 11-year-old girl, where her emotions—Joy, Sadness, Anger, Fear and Disgust, personified as different characters—conflict on how to help her best in her new life after her family moves. The story follows the "hero's journey" —a classical narrative（叙事的）framework, which involves a hero who goes on an adventure, overcomes challenges, and return s changed. So the research team chose this film. When making this film, the film-makers had in-depth discussions with psychologists to make the emotion animation consistent with scientific knowledge. 

The research team asked mostly open-ended questions to encourage the children to share their thoughts, including the key question: "Was there a part of the movie you had to think about?" Children looked at stills of important scenes and were invited to explain in their own words what happened. If they liked, they also rewatched scenes of the film. 

While watching, children made sense of the feelings, motives and behavior of characters in the film, using their social intelligence skills. They also further developed these skills when they were challenged in making sense of the story. Children also mentioned they appreciated seeing acts of pity, kindness, love and bravery in the film. Just like adults, they were even touched to tears by these qualities. 

One of the children in the study even expressed that Joy inspired her to never quit in her own life. The more insights children gained while watching, the more meaningful the story became for them. Altogether, stories in movies can be a quick way for children to gain life experience and wisdom. 

If you've ever seen a sparrow steal your dog food or a crow open a garbage bag, you get a sense of that some birds have learned to take advantage of new feeding opportunities—a clear sign of their intelligence. Scientists have long wondered why certain species of birds are more innovative than others, and whether these capacities stem from larger brains or from a greater number of neurons（神经元） in specific areas of the brain.

It turns out that it's a bit of both, according to a recent study by an international team that included members from McGill University published in Nature Ecology and Evolution.

The researchers used a new technique to estimate the number of neurons in a specific part of the brain called the pallium in 111 bird species. The pallium in birds is equal to the human cerebral cortex（大脑皮层）, which is involved in memory, learning, reasoning, and problem-solving, among other things. When these estimates about neuron numbers in the pallium were combined with information about over 4,000 feeding innovations, the team found that the species with the higher numbers of neurons in the pallium were also likely to be the most innovative.

"The amount of time chicks spend in the nest as their brains develop might also play acrucial role in the evolution of intelligence," says McGill University Emeritus Professor Louis Lefebvre who spent more than 20 years gathering examples of feeding innovations. "Larger species of crows and parrots, which are known for their intelligence, spend longer in the nest, which allows more time for the brain to grow and accumulate pallial neurons."

The results of the study help to deal with previously opposed views of the evolution and significance of brain size and show how a life-history perspective helps to understand the evolution of cognition.
