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!

    When was the last time you told someone they inspire you to go to work each morning?

    Teachers at Oak Park High School in Kansas City, Missouri, did just that this September, when they pulled individual students out of class to tell them just how much they appreciated them.

    The students' reactions, which were captured (捕捉) on video and shared on YouTube in a now-viral video, ranged from shy thanks to hugs and tears.

    “I have been challenged to find a student who makes me want to come to school every day,” says one teacher in the video, “and that's you.”

    Jamie McSparin, a teacher in charge of the school's academy program for at-risk sophomores （二年级学生）and juniors, posed the challenge, writes ABC News.

    “Initially when we pulled the kids out, they all thought they were in trouble,” McSparin told ABC News. “Any teacher-student interaction always seems to be negative (消极的), and that was something that bothered me, too. No matter if they're a good kid or a trouble maker or anything, they always thought they were in trouble,” she says.

    McSparin says she got the idea for the project after attending a professional development workshop this summer called the power of positivity.

    “I like the idea of letting students know they are appreciated, because we do appreciate them, I just don't think we say it enough,” she told local news outlet WDAF-TV.

    It's safe to say the challenge was effective.

    “I feel special,” said one of the boys in the video. “You should,” said his teacher. “You are special.”

    The wonderful experiment I am going to introduce proves that air is just all around and that it presses down upon us. Air pressure is a wonderful force. When you swim underwater, you can feel water push down your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth's surface.

    The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now for the experiment！

    What you need:

·A hard-boiled egg without the shell

·A bottle with a neck slightly smaller than the egg

·A piece of paper

·A match

Method:

1） Check that the paper will sit firmly on the neck of the bottle.

2） Tear the paper into strips and put the strips into the bottle.

3） Light the paper by dropping a burning match into the bottle.

4）Quickly sit the egg on the neck of the bottle.

Result:

    Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.

    Why it happened

    As the paper burns, it needs oxygen and uses up the oxygen（air）in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on it.

    When a child is told he is "uncool", it can be very painful. He may say he doesn't care, and even act in ways that are different from cool on purpose(故意地）. But these are simple ways to deal with sadness by pretending it's not there.

    Helping a child feel better in school had to be careful. If you say, "Why are you worried about what other children think about you? It doesn't matter!" Children know that it does matter. Instead, an active way may be best. You could say, "I'm going to do a couple of things for you to help you feel better in school."

    If a boy is having trouble making friends, the teacher can help him. The teacher can arrange things so that he has chances to use his abilities to contribute to class things. This is how the other children learn how to value his good qualities and to like him. A teacher can also raise a child's popularity in the group by showing that he values that child. It even helps to put him in a seat next to a very popular child, or let him be a partner with that child in activities, etc.

    There are things that parents can do at home, too. Be friendly when your child brings others home to play. Encourage him to invite friends to meals and then serve the dishes they consider "super" .When you plan trips, picnics, movies, and other shows, invite another child with whom your child wants to be friends.

    What you can do is to give him a chance to join a group that may be shutting him out. Then, if he has good qualities, he can start to build real friendship of his own.

    King's College Summer School is an annual (年度的) training program for high school students at all levels who want to improve their English. Courses are given by the teachers of King's College and other colleges in New York. Trips to museums and culture centers are also organized. This year's summer school will be from July 25 to August 15. More information is as follows：

    It was many years ago. I was a young dad sitting on the couch reading a fairy tale to my little girl. She sat next to me with her head on my arm as I told the tale. When it came to the end I finished with those famous words: "And they lived happily ever after." As I looked over to her with her wavy(鬈曲的), brown hair and big, innocent eyes I could see the smile on her face and I never wanted it to end. Then it dawned on me that the ending of the book was what I wanted for her. I wanted her to "live happily ever after".

    Still, deep in my heart I knew that this couldn't always be so. I knew that there would be times when her heart was broken. I knew there would be times when she cried in grief and I couldn't comfort her. I knew there would be times when all she felt was fear, sadness, sorrow, and despair. As I stroked her hair and smiled at her I hoped that those times would be brief and that she would have joy in her life more often than not. Living happily ever after, though, seemed out of the question.

    It takes me a lot of years to realize that it is possible to live happily ever after. You just have to do it "one day at a time". Happiness you see isn't some reward that you get at the end of your journey. Happiness isn't something that depends on what life you own. Happiness is something you create in your life choice by choice and day by day.

    The truth is happiness comes when you love. Love is a gift from God. It is love that mends broken hearts. It is love that heals grief. It is love that gives us joy. Choose to "live happily ever after, one day at a time".
