Naturally, parents praise their kids. They want to encourage their children every day. But when it comes to building self-esteem (自尊) in children, praise doesn't always have a positive effect, according to a special edition of the journal Child Development. The issue, edited by Eddie and Thomas, is focused on research into how children develop a sense of self and building your child's confidence takes different skills than you might think.

    Eddie points out that children are born without a sense of self, but it doesn't take long before some kids have a lot of confidence and may feel superior to peers, while others may carry more self-doubt and see themselves as inferior. Yet no one really understands what causes children to view themselves the way they do. Surprisingly little is known about the origins of children's self-concept,” Eddie said.

    Research has found that when kids have a warm, loving relationship with their parents, they develop higher self-esteem. However, when they are given endless praise that is inequal to their achievements, their self-esteem may drop.

    Instead of lavish praise, parents should focus on warmth to build self-esteem, researchers have found—specifically, parents should show interest in their kids' activities and share joy with them. This makes children feel noticed and valued. According to Eddie's own research, children may develop lower self-esteem when their parents give them lots of positive and overstated praises. Too much praise can make children worry about disappointing their parents, and may lead to an unhealthy attitude toward failure. Other studies suggest that parents can teach children that failure is beneficial by encouraging kids to ask themselves: “Why didn't I achieve the result I wanted, and what can I do to change the outcome in the future?”

    Additionally, it's important for parents to encourage the belief that kids can develop basic abilities through devotion and hard work. Kids who are praised for their effort instead of their ability are more likely to develop a growth mindset, which have a positive impact on their confidence.

    An old farmer lived on a farm with his young grandson. Each morning Grandpa was up early to read his holy. His grandson wanted to be just like him and tried to imitate him in every way he could.

    One day the grandson asked, "Grandpa! I try to read holy（圣书） just like you but I don't understand it, What good does reading the holy do?"

    The Grandfather quietly turned from putting coal in the stove and replied, "Take this coal basket down to the river and bring me back a basket of water." The boy did as he was told, but all the water leaked out (漏出) before he got back to the house. The grandfather laughed and said, "You'll have to move a little faster next time," and sent him back to the river with the basket to try again. This time the boy ran faster, but again the same took place. He told his grandfather that it was impossible to carry water with a basket.

    The old man said, "You're just not trying hard enough," So the boy again dipped the basket into the river and ran hard, but when he reached his grandfather the basket was again empty, he said, "See Grandpa, it's useless!", "So you think it is useless?" The old man said, "Look at the basket."

    The boy looked at the basket and for the first time realized that the basket was different. It had been changed from a dirty old coal basket into a clean one inside and outside.

    "You might not understand or remember everything, but when you read it, you will be changed, inside and out. That is the work of Krishna in our lives."

    You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

    Jane Addams(1860-1935)

    Anyone who has ever been helped by a social worker has Jane Addams to thank. Addans helped the poor and worked for peace. She encouraged a sense of community(社区)by creating shelters and promoting education and services for people in need . In 1931, Addams became the first American woman to win the Nobel Peace Prize.

    Rachel Carson(1907-1964)

    If it weren't for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world's lakes and oceans.

    Sandra Day O'Connor(1930-present)

    When Sandra Day O'Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator(参议员) and ,in 1981, the first woman to join the U.S. Supreme Court. O'Connor gave the deciding vote in many important cases during her 24 years on the top court.

    Rosa Parks(1913-2005)

    On December 1, 1955, in Montgomery, Alabama, Rasa Parks would not give up her seat on a bus to a passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott. It lasted for more than a year, and kicked off the civil-rights movement. "The only tired I was, was tired of giving in," said Parks.

    When I was a boy, my parents and I traveled from New York City to the Pennsylvania countryside for a weeklong taste of rural life. We stayed in a guesthouse on a farm, joining the daily routines and eating meals with the farmer and his family. We got up early to see the cows as they were milked. I even tried my hand at milking one, and then joined the farmer as he released the cows into the field afterward.

    Decades later I still have vivid memories of that trip which made me realize the value of a vacation, of seeing new things, meeting new people and sharing memorable experiences with family members. To this day, I still consider that family trip when I plan to take time off with my wife and kids. Vacations are a time for resting and connecting. As a bank manager, I spend much of my workday encouraging my customers to save their money. One of the reasons I give is that we should all have enough for a family vacation every year. In our busy lives, family is what we should be saving our money and time for.

    For my family, our vacation starts when we begin planning the trip. We talk about destinations and our budget (预算) ahead of time. Among the things we discuss: Can we save money by renting a house instead of spending six nights in a hotel? Would it be better to buy groceries and cook for ourselves rather than eat out every night? Involving (使参与) the kids in planning the vacation makes sure that they have a great vacation too. I prefer to visit historical sites and museums while they love to fish and swim. So I build in some relaxation time for us all so that the vacation can work for everyone.

    Each year, setting aside vacation time to spend together is especially important to us. A relaxing environment opens the doors to all kinds of conversations—deep, silly or meaningful. There's no pleasure from the usual everyday tasks. What matters is that everyone is having a great time.

    It is well known that male humpback whales(座头鲸)are skilled singers. Their songs are thought to attract females in high frequency sounds while to compete with other males in low frequency sounds. Research led by the Wildlife Conservation Society has now made a new discovery.

    The study looked at the songs of two humpback whale populations, based on sound recordings collected from 2013 to 2018. One group was based in the South Atlantic, off the coast of Gabon, and the other in the Indian Ocean near Madagascar.  Analysis of the recordings showed that the two groups picked up musical ideas from each other and borrowed phrases and themes into their latest song. This suggested that the males from the two groups came into contact with each other over the five years and shared songs.

    To uncover this musical cooperation, researchers recorded the songs and transcribe them into more than 1,500 individual sounds and patterns, or song units.  They found that the units were composed into larger phrases, which were then repeated to form themes. These themes were sung for hours at a time, or even days. By 2018, both populations have been singing largely the same songs.

    "This similarity in the songs shows that these two populations come into closer contact than other southern populations, explains Dr Melinda Rekdahl, leading author of the study. As well as being an interesting phenomenon, she explains that those songs allow even greater insight into the workings of the humpback whale populations.

    You may think there are no differences between British and American people. After all, they speak the same language, don't they? If you ask a British or an American person, he will probably tell you that there are differences. And the differences are quite great.

    What do British people think American people are like? The British think American people are very strange. They make a lot of noise and they laugh too loudly. They are rich, and they only think about money. But the British do say that American people are kind, and friendly people. They're happy to help you if you are in trouble.

    What do Americans think of the British? Well, they think the British are cold and very unfriendly. They are not interested in success or in making lots of money. They think British is the best country in the world. They look down on other countries. But Americans say that the British are quite hard workers. They are brave and honest. And in time of trouble they face difficulties happily.

    You can see that these ideas can cause misunderstanding between the British and Americans. But when American and British people become friends, they usually find things are not as bad as they expected.
