    Recently, my mother asked me to drop off some letters at the post office and pick up some stamps for her. Without giving it a thought, I took the letters and purchased her stamps.

    A few days later, she mentioned that one of the letters I had mailed was missing a stamp, and asked me if I had put a stamp on it. She had remembered asking me to put a stamp on it, though I certainly had not heard her. So, unfortunately, it looked like the letter, which was a bill of course, would come back marked "Return to Sender for Insufficient Postage". A few days went by and I returned to the post office to pick up our mail. While I was there, I saw the postmaster and happened to tell him about Mom's letter missing the stamp. I asked him to be on the lookout for it coming back. It was then that he told me his story. "You know," he said, "I immediately saw after you had dropped the mail off that your letter was missing a stamp. I also noticed that it was a bill for a credit card company. I thought to myself that you have always been kind to me and my partner, and I wanted to return the favor. So, to prevent your mother from getting charged a late fee from the credit card company, I took money from our change dish (extra pennies for folks who need one), and purchased a stamp for you."

    When I heard it, I couldn't believe it. What a blessing that was! I thanked him over and over again for putting the stamp on the letter for us. Then, I immediately dumped(倾倒) all the change out of my purse and into the penny dish in order to help others out in the future. When I got home, I was able to tell Mom the good news. This was kindness karma(因果报应) in action, I believe!

    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.

    David Rees runs a truly distinctive business. He charges customers $15 to shar pen their pencils to perfections, using a variety of tools.

    I know what you're thinking — is this a joke? The 39-year-old gets asked that question a lot. To clarify everything, he even created a special section on his website telling everyone he's actually providing a real service.

    You can supply your own pencil or you can have Rees sharpen one of his own favorite 2B pencils. After that, he mails it to you in a display tube with the shavings in a separate bag, and an authentic certificate which just happens to mention the pencil is so sharp as to be a dangerous object.

    To achieve the desired result, the master sharpener uses all kinds of tools, including general sandpapers, pocket knives and even a special $450 sharpening machine. "It depends on what the customer wants to use his/her pencil for," he says. "That determines the most appropriate pencil-sharpening technique.

    Some customers buy pencils as inspirational symbols while others buy them because of their special memories of classic 2B pencils.

    $15 to have a pencil sharpened is a bit expensive though, right? You're not the only one who feels that way, and David's unique business has really angered lots of people, who talk of inequality in America, saying it is so insane for the wealthy to pay $15 to sharpen a pencil. But others will say, "This is just our urge to put an end to the welfare state because new ideas arise along with the business."

    David admits his trade is sort of unusual. But there are those who actually value his service, as proven by the over 500 orders he has gotten.

    A couple of weeks ago, my oldest son, 9-year-old Hayden, came home from school and told me about his friend Katie's blog. Then he asked, "Can I start my own blog?" I thought it was a great way for him to learn new things. So I asked, "What would you want to write about?" Then we had a chat about a few choices. Eventually, Hayden decided on a particular animal species so that he could help other school kids learn about them.

    That Friday night, we set up a blog for him and Hayden's Animal Facts was born. He has posted four times so far. As we talked about starting a blog, I thought about some problems of a child blogging. Here are a few of the considerations that I had.

    Blogging isn't a popularity contest. At first, Hayden cared too much about how many views he had. After a couple of discussions, he now realizes that it's more important to come up with helpful contents for those who want to learn more about animals.

    Online security. I'm concerned about online security, so I make sure that there isn't too much personal information about him.

    The value of persistence (坚持). In so many ways, blogging is like a marathon. Keeping blogging teaches him the value of persistence.

    Writing and spelling skills. Much to my surprise, Hayden is terrible at spelling. However, he loves writing, has a great imagination and is always working on little books, so hopefully the process of blogging will help him with his writing and spelling skills.

    Most of us have looked up at the stars that fill the night sky and wondered whether we're alone in the universe. Indeed, the question of whether there's life out there has been something humankind's been asking itself for countless years. But thanks to China's Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

    The telescope has a huge round reflector, which measures 500 meters across and has a perimeter(周长)of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST's designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. "Panels can change their positions through connected wires and parallel (关联的) robots. We can control their position with an accuracy of 1mm," Zheng Yuanpeng, chief engineer of the telescope's panel project, told Xinhua News Agency.

    FAST's engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. "There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST's construction, told Xinhua.

    And although it wasn't yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars (脉冲星) have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.
