Seal(海豹) seizes raft

    This seal really rocked the boat when he found himself an unusual place to hang out. After the seal came across a boat in the harbor where he lives, he fell inside and wouldn't budge for four days.

“One morning the seal just pulled himself aboard,” says Ed Stubbings, who owns the boat-turned-bed. Probably thinking the boat was a rock, the seal made himself at home. The seal didn't move an inch—--not even to eat or drink.

    Stubbings was a little worried that the 500-pound animal might sink it. Luckily on the fifth day, the seal fell back into the water and swam off.

Alligator(短吻鳄)gets new tail

When Mr. Stubbs the alligator swims through his pool at the Phoenix Herpetological Society, he looks like any other gator—--except that his tail is made of rubber. Mr. Stubbs is the first alligator known to wear an artificial tail.

    Mr. Stubbs was brought to the society nine years ago. “His tail was missing when he arrived,” says President Russ Johnson. Mr. Stubbs couldn't walk or swim properly. “We showed him how to swim in the water,” Johnson says. “But that hurt his back.” Later, the scientists used rubber to build an artificial tail attached to Mr. Stubbs's back legs. “Once we put the tail on him, he walked with ease,” Johnson says.

Dog delivers papers

    Morgan started her “paper route” when she was young. One day as Morgan and her owner Bill set out on a walk, she spotted a rolled-up paper. To Bill's surprise, Morgan grabbed the object in her mouth, walked back to the house, and dropped it on the doorstep. Morgan enjoyed the activity so much that she wanted to deliver every paper she saw on her walks.

Now three-year-old Morgan brings the paper to her owner and neighbors, even in bad weather. “Morgan has a natural instinct(本能) to carry things with her mouth,” dog behaviorist Pat Miller says. “And she feels rewarded by the activity, so she keeps it up.”

    Adults are happy to tell their children that crusts (面包皮) will give them curly hair, carrots will help them see in the dark, and spinach will make them strong. Even though adults know it's not totally true, they think it's good for their children's health, a study had found.

    In a study about 31 per cent of adults said they once told their children the curly hair tale, and 36 per cent said they'd been told the same thing by their mother or father. Among the over-50s, almost half said they'd been promised curly hair if they ate their crusts. A quarter of the 2,000 adults questioned in the study told their children carrots would help them see in the dark. This could be true to some extent because of the high levels of vitamin A and beta-carotene in root vegetables.

    Another favorite among parents is that milk will make one strong. A third surveyed said their parents told them this, and about 29 per cent said they told their children the same thing. But while there is plenty of evidence to suggest milk is good for people's health, there are also a lot of scientific papers saying it isn't.

    Thanks to Popeye, spinach is also fed to children, along with the idea that it will make them strong. While there is also some truth in this one, scientists now believe it is not the iron, but the inorganic nitrates (无机硝酸盐) that improve physical power.

    One in seven of the surveyed admitted telling their little ones that runner beans will make them run faster, which is nothing more than wordplay and has no basis in science. Almost one in five adults were subjected to the same tale in childhood.

    Just over one in 10 parents told their children green food would turn them into a superhero, and a quarter admitted hiding vegetables in meals.

    Lyndsay Jones, spokesman for Persil Washing Up Liquid, said, "It's clear that the most persuasive stories about food are passed on from generation to generation. Our research shows that the ideas continue, and we tell our kids the same things our parents told us, even if they're not always entirely true."

    Crusts may not make your hair curly, but there's plenty of research that says crusts contain more of the goodness than the rest of a loaf. Hopefully, as a result of our Cook with Kids promise, more parents will be encouraged to spend time with their children in the kitchen and teach them the truth about food.

    As a Chinese saying goes, “Taste is actually a memory of childhood”. Local specialty food may not be popular among all people, but it offers outsiders a glimpse of local culture and history.

    Gongcheng “oil tea” is such a kind of food that would be considered “weird” by many first-time visitors to the remote county in the north of the Guangxi Zhuang Autonomous Region. Many people dislike its bitter and astringent（涩的）flavor when they take a sip.

    “It felt like drinking Chinese herbal medicine. I never expected that I would gradually accept it afterwards, and even become addicted to it,” said a traveler surnamed Zhang who comes from Shijiazhuang in northern China's Hebei province.

    Langshan village is said to be birthplace of Gongcheng “oil tea” whose ideal ingredients are green tea and fermented（发酵）tea. The village has preserved well its buildings and roads dating back to late Qing Dynasty (1644-1911), as well as its traditional way of making the special tea.

    Lin Fengyou, 60, introduced the cooking process. She looks younger than her age, and attributes this to the benefits of drinking “oil tea” throughout the year.

    The first procedure is to use a wooden hammer to pound the tea while heating it in an iron pot, and then add edible（可食用的）oil and boiled water afterwards. She filters off the solid residues（余渣）, and pours the glue-like green tea soup into bowls. Then, she adds salt, caraway seed（葛缕子籽）, green onion, dried rice, fried groundnuts, sliced taro（芋头）and fried beans.

    The taste of the “oil tea” is a mixture of the distinctive（特有的）flavors of all its ingredients. Local people usually eat it together with glutinous rice（糯米）balls, rice dumplings and glutinous rice cake.

    The villagers consume “oil tea” three times a day. The tea soup is a healthy and refreshing food. “The tea soup to us is coffee to Westerners”, said Lin. “But it is tastier.”

    You can use your smartphone to get pretty much anything delivered directly to your door almost immediately. The hardest part is the process of trying to work out if you should tip and if so, doing the quick math before you get to the door. And, you know well that you should tip about 15-20% at restaurants, but do the same rules apply to delivery drivers?

    The co-founder of Grubhub, Matt Maloney, pretty much set the standard for tipping delivery people in a Facebook post. He's a strong supporter of tipping, and Grubhub's website suggests a $5 or a 20% tip. Maloney also said this number should go up if you order during, say, a snowstorm.

    However, most other delivery services say on their websites that tipping is not required. Some services, like Door Dash, do suggest no tip on their checkout window. Many, like Amazon Prime Now, allow customers to change their tip amount after their delivery has been received to reflect the quality of service. These companies help customers save money but delivery drivers are upset. They deal with bad weather, heavy traffic, extreme tiredness, and more, all for a $1 tip. Many feel that if you'd tip your pizza boy or girl, you should tip your delivery driver.

    The Emily Post Institute (EPI)'s official suggestion falls in line with Maloney's: “10-15% of the bill, or $2-5 for pizza delivery depending on the size of the order and difficulty of delivery.”

    Just like servers in a restaurant, delivery drivers almost always rely on your tips for their income. Tipping is a long-standing cultural tradition in America. So, until drones (无人机) can deliver hot dogs straight to your door, it's best to tip the people riding through the city at all hours to bring you hot fresh food.

    From quiet paths by a stream in a forest to busy roads running through a city, people have created various forms of routes in different places. These now exist all around us, and their use is imperative for societies. These routes have enabled people to move, transport things, and send information from one place to another quickly and safely. Throughout history, they have been important in our daily lives.

    Early routes were often formed naturally on land. They gradually developed over long periods of time while people traveled them on foot or horseback. A significant turning point in their history arrived when the first wheeled carts appeared in ancient times. Once this happened, people recognized the importance of well-maintained routes. Therefore, towns, cities, and entire countries improved them. As a result, life became more convenient, communities grew, economies evolved, and cultures expanded.

    People have established routes on water, too. Rivers and canals have served as effective routes for people to move around and carry things. For instance, in the old, Japanese city of Edo, water routes were used for the transportation of agricultural products, seafood, and wood. People have also opened routes across the sea. The seaways were critical for the navigation of ships, particularly in the days when they moved mainly by wind power. Using these sea routes, people could travel great distances, and go to places they had not previously been able to reach.

    People have gone on to open routes in the sky as well. Since the invention of the airplane, they have made it possible to travel long distances easily. Eventually, people became able to travel safely and comfortably high in the sky, and going vast distances only took a small amount of time.

    Today, we have a new type of route, the Internet. By using this worldwide route, people can easily obtain information that once was available mainly from books and face-to-face communication. They can also instantly send messages to large numbers of people all at once.

    As long as there have been people, there have been routes to connect them. Currently unknown routes will surely take us even further in the future.

The ancient Egyptians thought so little of the brain that when a king died, they removed the brain from his body and threw it away. The Egyptians assumed, like many people before and after them, that consciousness — your mind and your thoughts existed in the heart.

Now we know that the mind is a product of the brain, but how exactly does this 1.5-kilo piece of matter create a mind that allows you to think about yourself, experience happiness and anger, or remember events that happened 20 minutes or 20 years ago? This isn't a new question. Today, however, powerful new techniques for visualizing the sources of thought, emotion, behavior, and memory are transforming the way we understand the brain and the mind it creates.

Have you ever stopped and thought, "What's wrong with me today? I just don't feel like myself"? Perhaps you were more tired or worried than usual — but somehow, you knew that something was different about you. This self-awareness - the ability to think about yourself and how you're feeling-is an important part of being human.

This part of of your mind has its origins in the prefrontal cortex — a region of your brain just behind your forehead that extends to about your ears. Before this area began to function (around age two), you didn't understand that you were a separate individual with your own identity. As this part of your brain developed, you became more aware of yourself and your thoughts and feelings.

Though humans may share certain emotions and recognize them in others, we don't all have the same emotional response to every situation. In fact, most emotional responses are learned and stored in our memories. The smell of freshly cut grass, for example, will generate happy feelings in someone who spent enjoyable childhood summers in the countryside, but not in someone who was forced to work long hours on a farm. Once an emotional association like this is made, it is very difficult to reverse it. "Emotion is the least flexible part of the brain," says psychologist Paul Ekman. But we can learn to control our emotions by becoming consciously aware of their underlying causes and by not reacting automatically to things in our environment.

For centuries, people have studied the brain, but it is only in recent years that we have really started to learn how it works. Nevertheless, there is still a long way to go before we understand our mind's many complexities.
