    It is difficult for parents of nearly every family to teach their children to be responsible for housework, but with one of the following suggestions, you really can get your children to help at home.

    If you give your children the impression that they can never do anything quite right, then they will regard themselves as unfit or unable persons. Unless children believe they can succeed, they will never become totally independent.

    My daughter Carla's fifth-grade teacher made every child in her class feel special. When students received less than a prefect test score, she would point out what they had mastered and declared firmly they could learn what they had missed.

     You can use the same technique when you evaluate (评价) your child's work at home.

    Don't always scold and give lots of praise instead. Talk about what he has done right, not about what he hasn't done. If your child completes a difficult task, promise him a Sunday trip or a ball game with Dad.

    Learning is a process of trying and failing and trying and succeeding. If you teach your children not to fear a mistake of failure, they will learn faster and achieve success at last.

    Most American students go to traditional public schools. There are about 88,000 public schools all over the US. Some students attend about 3,000 independent public schools called charter schools.

    Charter schools are self­governing. Private companies operate some charter schools. They are similar in some ways to traditional public schools. They receive tax just as other public schools do. Charter schools must prove to local or state governments that their students are learning. These governments provide the schools with the agreement called a charter that permits them to operate.

    Charter schools are different because they do not have to obey most laws governing traditional public schools. Local, state or federal governments cannot tell them what to teach. Each school can choose its own goals and decide the ways it wants to reach them. Class size is usually smaller than in traditional public schools.

    Governments strongly support charter schools as a way to re­organize public schools that are failing to educate students. But some education agencies and unions oppose charter schools. One teachers' union has just made public the results of the first national study comparing the progress of students in traditional schools and charter schools.

    The American Federation of Teachers criticized the government's delay in releasing the results of the study, which is called the National Assessment of Educational Progress. Union education experts say the study shows that charter school students performed worse in math and reading tests than students in regular public schools.

    Some experts say the study is not a fair look at charter schools because students in those schools have more problems than students in traditional schools. Other education experts say the study results should make charter school officials demand more student progress.

    If you live in a big city, there are many thing to drive you crazy on your daily route, and it's not just overcrowded subway trains.

    Vicky Zhao is a mainlander working in Hong Kong. For her, one thing she can't put up with is people standing on the wrong side of the escalator(自动扶梯) in subway stations. "Escalators help us move faster and save time. It isn't a place to rest," the 24-year-old says. "I often see tourists block the way with their suitcases or chatting on the escalators during rush hours. It annoys me to no end."

    Admitting she is not the patient type, Zhao says things are much better in Hong Kong than in cities on the mainland where "stand right, walk left" signs are often ignored.

    The logic behind the "stand right, walk left" escalator etiquette(礼仪) seems obvious. Even though you may want to catch your breath while you're transported up or down, you should still consider others and leave enough space for people in a hurry, so that they can run and catch the train.

    Many cities' escalators, including London's and Beijing's, use the "stand right, walk left" system to speed up the flow of people. (Australia is an exception and you should stand on the left side instead.) But some cities discourage people from moving on escalators out of safety reasons. In Hong Kong's subway stations there are regular announcements asking people to "stand still" on escalators. Even so, most people in this fast-paced city observe the "stand right, walk left" etiquette.

    But the people who stand on escalators defend themselves by telling the walkers not to be so impatient. The BBC quotes one stander as saying: "If the person is in such a rush, why not just take the stairs? Even when the escalator is packed and there's nowhere to move, I see these same people complaining about not being able to pass."

    Whatever the escalator etiquette is in the place you live or visit, do what most people are doing and always be mindful of others: leave enough space between each other, don't stay at the end of the escalator, and if someone is blocking your way, a simple "excuse me" is enough.

    Three years ago when I was still in the university, I also worked at a restaurant.

    An old man named Mr. Candido Filio was one of our regular customers at the restaurant. He was one of the most intelligent people I've ever known.

    Every Sunday the Philippine Star Newspaper had a special page for word puzzles and among his peers (同龄人), Mr. Filio held the record for solving all the puzzles in less than five minutes. He encouraged me to solve them too and for months and months, I did my best to beat him but failed.

    Then one Sunday, I did it! I was able to complete them before anyone else. Everyone cheered for me. He came up to me with a smile and said, "No one has ever beaten me before. You're the first. I'll have a prize for you tomorrow."

    The next day, he gave me a special Scrabble (拼字游戏) set. I would have never been able to afford one like that by myself. Then he said to me, "Kate, what do you think is man's final goal in life? Happiness, isn't it? You are happy and that should be considered as a success. Many people spend a lifetime searching for that. Be thankful that you have found it." I looked at him and knew that my life had changed, probably forever. He must have known that I always felt sad about not having much money.

    He encouraged me to learn the game and love words. And true to his words, I was never able to beat him again.

An airline passenger ensured a 20-year-old man was reunited with his lost wallet-along with a little extra something to make up for their time apart.

Hunter Shamatt first lost his wallet while he was on a Frontier Airlines flight from Omaha to attend his sister's wedding in Las Vegas earlier this month. On realizing his wallet was lost, he contacted the airline to see if anyone had turned it in—but to no avail. Since the wallet contained his ID, a signed paycheck, his debit card and $60 in cash, he "feared the worst".

Shortly after the flight, however, Hunter was shocked to receive a package in the mail from an unknown sender. Inside was his wallet-along with an additional $40 in cash.

"Found this on a Frontier flight from Omaha to Denver-row 12, seat F stuck between the seat and wall," read a letter in the package. "Thought you might want it hack. All the best. PS: I rounded your cash up to an even $100 so you could celebrate getting your wallet hack. Have fun!"

Hunter's mother, Jeannie, posted a photo of the letter to social media in hopes that they would be able to track down the sender and thank them for their kindness. All they had to go on was that the letter was sent from Applied Underwriters in Omaha and the sender's initials were signed: "T.B".

The Good Man was later identified as Todd Brown, a father-of-five who was delighted at the chance to "have a little fun" with helping out a hard-working stranger. Brown says that he often tries to do good deeds without any recognition, thus why he didn't sign his full name on the letter, but Jeannie later insisted on praising the Nebraska native on social media.

"I try to teach my children to do the right things in life, help people when you can despite the outcome," she wrote on Facebook. "This story is more about restoring faith in people than anything".
