Two of the saddest words in the English language are "if only". I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.

    My father is famous in our family for saying, "Take the extra minute to do it right." I always try to live by the "extra minute" rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an "if only" moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.

    I don't only avoid those "if only" moments when it comes to safety. It's equally important to avoid "if only" in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say "I love you" or "I forgive you." When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn't be here. But then I thought about the fact that he's 84 years old and I realized that I shouldn't give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.

    I know there will still be occasions when I have to say "if only" about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I'm doing the right thing. I'm buying myself peace of mind and that's the best kind of insurance for my emotional well-being.

    A new phone app uses shaking from smartphones to warn people about earthquakes. The new app is called MyShake, which is the work of four researchers at the University of California. Berkeley.

    Smartphones are equipped with accelerometers(加速器). MyShake uses phone accelerometers to measure seismic (地震的) activity. It has been programmed to know the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time. A smartphone sends seismic information to the app developers. If the developers receive several warnings from one area, it recognizes that an earthquake may be taking place or will take place soon. Using information sent from the app, the network then judges the location and strength of the quake in real time. MyShake can record 5.0 earthquake at distances of 10 kilometers or less.

    MyShake uses very little power, according to its developers. Only when seismic activity is sensed by the app does it become active and sends data to the network. The app works best when your phone is resting on a flat surface, like a table.

    The developers hope that MyShake can add to information collected by the U.S Geological Survey. That U.S agency has created the Earthquake Early Warning System, also known as the EEW. The EEW has used sensors for measuring quakes in many areas. In places where no such equipment exists, MyShake may be the only method of early quake detection (发现). The app also shows ways to stay safer during an earthquake. The developers say it will become more effective as more people use it.

    The developers say they hope to add a feature that will warn people about possible tsunami after an earthquake.

    Truman headed home from school, with the homework in mind, a report on beehives (蜂巢). Truman's class had studied bees for three days, so he was ready. But, as his teacher Mrs. Lawrence had explained, to earn an A +，he needed a “new angle”.

    Truman pushed open the front door to find his four-year-old brother, Bryan, sitting on the living room rag, hard at work. Paper towel tubes were all over the floor.

    Bryan quickly stood up. “Truman, help me build a city!”

    “I'd like to,” Truman replied, “but I have to do a report on beehives and ...”

    “Can I help you?” Bryan begged.

    “I don't think so, Bry. Sorry.''

    “I know where there's a beehive.” Bryan smiled.

    “Where?”

    “In the wood pile by the garage.''

    The boys marched to the firewood. Bending down, Bryan pointed out the hive deep inside the pile. Truman carefully removed the hive out.

    “You got it!” Bryan shouted.

    Back in the living room, Truman paced around, turning the fragile hive under his nose. Each cell was a perfect hexagon(六边形). How did the bees fit the cells together so neatly? And how did they make each cell six-sided? Could they count? Lost in thought, his foot came down on something ...

    “Truman! You're mining my city!”

    “Get your stupid tubes out of here，Bryan! I'm trying to…”

    The towel tubes on the floor suddenly reminded him of something. The beehive!

    Looking closer, he noticed the tubes were arranged with one in the middle, surrounded by six others, just like the cells of the hive.

    Just to be sure, he tried five and then seven tubes surrounding the center tubes, but neither way fit. Six was the only number that worked.

    “Bees don't count to six,” he said aloud. “The cells have to be six-sided.

    Truman ran to Bryan and threw his arms around his brother. Bryan, you did it! Now I can build a model beehive with your tubes! I mean — if it's O. K. with you.”

    The human brain remembers negative experiences more easily than positive ones. Our brains have developed this way because threats, like dangerous animals, had a more immediate effect on our ancestors' survival compared to positive things like food or shelter. As a result, you likely know what makes you unhappy, but do you know what makes you happy?

    Research suggests that our level of happiness depends partly on factors we cannot control—our genes and our life circumstances. But our level of happiness is also shaped by the choices we make. If you've been chasing wealth, fame, good looks, material things and power, you may be looking for happiness in all the wrong places. Psychologists suggest that the following habits make people happier.

    People who form close relationships tend to be happier than those who do not. The number of friends we have is not important. What matters is the quality of our relationships. Relationships that bring happiness usually involve the sharing of feelings, mutual respect, acceptance, trust and fun.

    People who exercise regularly improve both their physical and mental well being. Some research has shown that exercise can be as effective as medication in treating depression.

    When we are so interested in an activity we enjoy that we lose track of time, we are in a state of flow. The activity could be making art, playing piano, surfing, or playing a game. People who experience flow in their work or hobbies tend to be happier.

    People are more likely to be happy if they know what their strengths are and use them regularly, People who set goals and use their strengths to achieve them tend to be happier. People are especially happy when they can use their strengths to serve the greater good.

    People who think positively by being grateful, mindful and optimistic are more likely to be happy. Being grateful means being thankful, Bejing mindful means being open to, focusing on and enjoying the experiences of the present moment. Being optimistic means being hopeful about the future.

    I was ten when my father first sent me flowers. I had been taking ballet lessons for four months, and the school was giving its yearly performance. As a member of the beginners' chorus group, I was surprised to hear my name called out at the end of the show along with the leading dancers and to find my arms full of red roses. I can still feel myself standing on that stage, seeing my father's big smiles.

    Those roses were the first of many bunches accompanying all the milestones in my life. Getting all those roses was wonderful, but they brought a sense of embarrassment. I enjoyed them, but I also felt they were too much for my small achievements.

    Not for my father. He did everything in a big way. Once, when mother told him I needed a new party dress, he brought home a dozen. His behavior often left us without money for other more important things. Sometimes I would be angry with him.

    Then came my 16th birthday. It was not a happy occasion. I was fat and had no boyfriend. And my well-meaning father furthered my suffering by giving me a party. As I entered the dining room, there on the table next to my cake was a huge bunch of flowers, bigger than any before.

    I wanted to hide. Now everyone would think my father had sent flowers because I had no boyfriend to do it. Sweet 16, and I felt like crying. But my best friend, Jenny, whispered, "Boy, you're lucky to have a father like that."

    As the years passed, other occasions—birthdays, awards, graduations—were marked with Dad's flowers. Those flowers symbolized his pride, and my success. As my fortunes grew, my father's health became worse, but his gifts of flowers continued until he died. I covered his coffin with the largest, reddest roses I could find.

    Often during the dozen years since, I felt an urge to buy a big bunch to fill the living room, but I never did. I knew it would not be the same.

    Then one birthday, the doorbell rang. I was feeling blue because I was alone. My husband and my two daughters were away. My 10-year-old son, Tommy, had run out earlier with a "see you later". So I was surprised to see Tommy at the door. "Forgot my key," he said. "Forgot your birthday too." He pulled a bunch of roses from behind his back.

    "Oh, Tommy," I cried. "I love flowers!"
