A dog, it is said, is a man's best friend. Put a dog, a kid and a book together, and you have a struggling reader's best friend.

    The therapy dogs of R.E.A.D. – Reading Education Assistance Dogs – have been helping children improve their reading skills since 1999, when Intermountain Therapy Animals (ITA) began the program in Salt Lake City, Utah.

    Today, tens of thousands of R.E.A.D. teams – dogs and their owners – volunteer to spend time with youngsters in schools and libraries across the United States and around the world. The idea is that sharing a book with a nonjudgmental (不带评论的) partner encourages students' confidence and helps develop a love of reading.

    Izzy, a Havanese therapy dog, is a regular visitor to Public School 57 in East Harlem, New York. Students meet him in the library, pick out a book and sit down on the carpet. Izzy snuggles (依偎) up to them and gets ready to hear a story.

    “I love reading to Izzy because he listens to me, and he doesn't make fun of me when I make a mistake,” says third-grader Aelane Vasquez. The 9-year-old, whose parents are from Mexico, is one of 15 Latin-American students at the school who were selected for the program.

    “All the students that we work with in the R.E.A.D. program were behind reading levels at the beginning of the year,” Bridget McElroy, who teaches English as a Second Language, explained. “Now most of them have reached the average level, if not above it.” That's important, because achieving proficiency (熟练) in reading is vital for kids to succeed. Studies have shown that students who can't read at grade level by the end of third grade are four times less likely to graduate high school by the age of 19.

    The R.E.A.D. teams from New York Therapy Animals work with 175 kids at Public School 57 and nine other schools.

    McElroy said she sees a marked difference in Aelane and her classmates, and not just in study. “Not only do the kids have time to practice reading, what we are really seeing is that they are excited to read and practice even when Izzy is not here,” she said.

    If you live in the U.S., you're probably used to throwing banana peel into the trash. But people in other countries, including India, have been taking advantages of their nutritional benefits for many years.

    While the flesh of a banana is soft and sweet, the skin is thick, hard and slightly bitter. To eat the peel, you can fry, bake, or boil it for at least 10 minutes. Also, the riper bananas get, the thinner and sweeter banana peel will become. That's because of a natural plant hormone(激素) called ethylene(乙烯) that fruits release as they ripen. Ethylene interacts with the sugars and fiber in the banana skin, changing complex sugars into simple sugars and breaking down pectin, a form of fiber in bananas that keeps them stiff. That's why the older your banana is, the flimsier(不结实的) it feels.

    The sweet flesh of a medium-sized banana contains great percentages of your daily recommended intake of various nutrients, such as:

·12% of your daily fiber, which helps with digestion and may help lower your risk of diabetes(糖尿病)

·17% of your vitamin C, which is important for your immune system as well as your growth

·20% of your vitamin B6, which aids the body's ability to turn food into energy

·12% of your potassium, which helps with the development of cells, tissues, and organs throughout the body

    If you eat the skin along with the flesh, you will get an even bigger increase in these same nutrients.

    Eating the peel is not only good for your body but also better for the earth. The average American ate 11.4 pounds of bananas in 2014. Since a medium-sized banana weighs about 0.3 pounds, that equates to about 38 bananas per person, or about 12 billion for the whole of the U.S. And since most of us throw away the peel, that also means a lot of organic waste.

I really love this saying, "Love is endless and unlimited." For me, there's a story behind it. When I used to hand out chocolates with beautiful paper bags, my friends always told me, "You are wasting time and money. No one here believes in nameless gifts." To be honest, I have noticed that people here do donate (捐赠)in temples. They give food to the poor, and provide clothes and other things for whoever is in need.

    I think maybe I am the one who starts to think of the dogs in our neighborhood. When I moved into this new community, I noticed that there were two street dogs. They were wounded and homeless, and everyone used to stay away from them and hit them when they came any closer. They were becoming thinner and thinner and they would did of hunger sooner or later.

    But my habit of loving dogs has changed all these things. I began to walk close to them and give them food regularly. When I touched their heads and gave love to them, I could see tears in their eyes. My friends noticed, and now even kids and elders in the community provide them with food and also love them. I am really glad to see that I saved their lives.

    What I started will lead to beautiful memories with them. They enjoy playing with me and they even have a particular pose when they see me. I see a sparkle in their eyes and a smile on their faces. They are priceless for me.

    Spending as little as $ 5 a day on someone else could significantly boost happiness, the team at the University of British Columbia found.

    Their experiments on more than 630 Americans showed they were measurably happier when they spent money on others—even if they thought spending the money on themselves would make them happier.

    "We wanted to test our theory that how people spend their money is at least as important as how much money they earn，" said Elizabeth Dunn，a psychologist at the University of British Columbia. They asked their 600 volunteers first to rate their general happiness，report their annual income and detail their monthly spending including bills, gifts for themselves, gifts for others and donations to charity.

    "No matter how much income each person made，those who spent money on others reported greater happiness, while those who spent more on themselves did not，" Dunn said in a statement.

    Dunn's team also surveyed 16 employees at a company in Boston before and after they received an annual profit sharing bonus of between $ 3, 000 and $ 8, 000. "Employees who devoted more of their bonus to pro­social spending experienced greater happiness after receiving the bonus, and the manner in which they spent that bonus was a more important predictor of their happiness than the size of the bonus itself，" they wrote in their report, published in the journal Science.

    They gave their volunteers $ 5 or $ 20 and half got clear instructions on how to spend it. Those who spent the money on someone or something else reported feeling happier about it.

    "These findings suggest that very minor changes in spending allocations—as little as $ 5—may be enough to produce real gains in happiness on a given day，" Dunn said.

    Babies teach their older brothers and sisters empathy (移情), according to a new research. Empathy means understanding and entering others' feelings. Until now, younger kids have generally been regarded to learn plenty from their older brothers or sisters but don't give back much. But this study, published in Child Development, confirms that younger siblings (兄弟姐妹) ensure their big brothers and sisters don't grow into disgusting people—no easy task.

    “Although it's assumed that older siblings and parents are the primary socializing influences on younger siblings' development but not vice versa, we found that both younger and older siblings positively contributed to each other's empathy over time,” study co-author Marc Jambon said in a statement. Prior sibling studies have focused on the influence of older brothers and sisters, probably because their impact is most obvious. As one review of literature notes, studies have shown that older siblings influence everything from their younger siblings' motor development to their risk of smoking later in life. And although separated studies have tried to pin down effects that younger siblings have on their older siblings, the influence of baby brothers and sisters remains unclear.

    For this new study, Jambon and his colleagues recruited (招募) a diverse group of 452 Canadian sibling pairs between the ages of 18 months and four years. At the start of the study, individual researchers assessed children's baseline empathy levels by visiting the kids at home and then pretending to hurt themselves or break a valuable item. Eighteen months later, they found small but significant increases in empathy.

    One unexpected exception—older sisters did not appear to experience increased empathy after 18 months living with their little brothers, specifically. The researchers aren't sure why this exception appeared, and they recommend that future studies dive into more complex phenomena.

I love hiking. In the mountains, the birds sing for me; the various trees and flowers overwhelm (征服) my eyes and the deep blue of the sky inspires me and makes me feel calm. Furthermore, I can breathe the fresh air, keeping away from the dust and pollution of the city. It seems that all my senses are awakened when I am in the mountains. More importantly, hiking teaches me a lot.

I have been a traveler since childhood and was drawn towards mountains and their beauty. Later my reading several travel books made me think if I could also go on such journeys. Finally, I decided to give it a try. After I was well-prepared to face all difficulties of the hike, I joined a group of hikers. On the way, we encouraged each other, took beautiful pictures, and sat down now and then to feel the breath of the land. All my worries disappeared and we talked and laughed just like kids. This journey excited me for a long time.

I never actually realized the need for water until I started hiking. I remember once I was on a hike where our water was not enough. It was a night hike and the next day we had to return back to our base camp following the same route. So we have to save it for emergencies (紧急事件).That day I exactly learned water is of great value and that we have a duty to save it.

Besides enjoying the beautiful natural views, you have to go out of your comfort zone and push yourself hard to challenge your normal limits when hiking. On a hike, you may sometimes get injured but you can't stop until you reach the destination. Every next try will surely make you stronger and happier if you embrace (拥抱) your injuries, pains and discomforts.

Sometimes we may have a conversation with those locals living in wooden houses. You know, mountain life is hard and difficult. But they never complain about their life. They are happy with what they have. Many times they are facing extreme weather and they just fight with them. They are so brave. What can we complain about?
