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.

    Tu Youyou, an 84-year-old female scientist, became the first Chinese to win a Nobel Prize in science on Oct 5. Before that, she ever won the 2011 Lasker Award for finding out artemisinin (Qinghaosu), which saved millions of lives. She was thankful for the Lasker prize, but said, “It is just a scientist' duty. I will go on fighting for the health of all humans.”

    Tu kept her work in the 1960s and 1970s. In that age, Malaria could took away people's health. Scientists all over the world had already tried over 240 000 times but failed. Tu Youyou, a member of the Academy of Traditional Chinese Medicine, Beijing, began to study Chinese herbs.

    Before 2011, people didn't know Tu very much. Many friends played jokes with her “the Professor of Three None's” : no degree, no study experience abroad, not a member of any Chinese national colleges. But she is hard-working. She read a lot of traditional Chinese medicine books and did a lot of researches on the disease.

    In February, 2012, Tu was named National Outstanding Females (One of the Ten) Tu is now a model of Chinese medical workers.

    The best city beaches: San Juan, Puerto Rico

    Being able to relax on a warm sandy beach in the middle of the winter is obviously a dream getaway, but not everyone wants their sand and surf to be hidden in a remote comer of an island. Instead, head to the sizzling（炎热的）city nightlife of San Juan, where the streets of chic Condado back right into the palm trees and lapping waves of the Atlantic beaches. Top chefs, stylish hotels, bars ， clubs, and shops are all just steps away from the tropical beaches. And since Puerto Rico is a United States Commonwealth, it's one of the easiest islands in the Caribbean to visit since you won't need a passport, have to change money, or even worry about your cell phone working. Puerto Rico is also one of the best tropical vacations you can take without leaving the United States.

    The best swimming holes: Riviera Maya, Mexico

    What's better than diving into the salty sea? Submerging in the crystal clear and salt-free waters of the naturally occurring limestone cenotes of the Riviera Maya and Yucatan Peninsula. Spend a sunny day exploring these natural cave pools filled cool filtered water that springs from the ground below and the lush palm forests that surround them. Then head back to the perfectly located Fairmont Mayakoba for comfortable rooms and modem Mexican cuisine.

    The best girlfriend getaways: New Orleans

    New Orleans vibrant nightlife and live-music scenes make the “Big Easy” a great girl's trip winter getaway (check out the Girl's Trip movie if you don't believe us).

Check out these other great weekend getaways for girls trips.

The amazing dolphins will probably make you want to hit the waves yourself, which won't be a problem since the beautiful white sand beaches here boast 361 days of sunshine per year. Next, don't miss these destinations that are even better in the winter.

    The full moon climbs over the eastern horizon (地平线) and hangs like a huge orange globe in the sky. A few hours later, the moon is overhead but seems to have changed. The huge orange globe has become a small silver disk. What has happened? Why has the orange color disappeared? Why does the moon seem so much smaller and farther away now that it is overhead?

    The moon appears orange on the horizon because we view it through the dust of the atmosphere. The overhead moon does not really shrink (缩小) as it moves away from the horizon. Our eyes inform us that the overhead moon is farther away. But in this position the moon is actually closer to our eyes than when it is near the horizon.

    The change in size is a trick our eyes and minds play on us. When the moon is low in the sky, we can compare its size with familiar objects. It is easy to see that the moon is much larger than trees or buildings, for example. When the moon is high in the sky, however, it is hard to compare it with objects on earth. Compared to the vastness of the sky, the moon seems small.

    There is another reason why the moon seems to shrink. We are used to staring at objects straight ahead of us. When an object is difficult to see, our eyes have to try to focus on it. When we move our heads back to look up, we will try hard again. Looking at something from an unaccustomed position can fool you into believing an object is smaller or farther away than it is. However, scientists do not yet understand completely why the moon seems to shrink as it rises in the sky.

    The saying, "Don't judge a book by its cover, means you should not guess the worth or value of something based on how it looks. That message was clear at a recent event called the Human Library Project. The event took place at the Northern Virginia, or NoVa, Community College, outside of Washington. D. C.

    The Human Library began 19 years ago in Denmark. It grew from a youth organization called "Stop the Violence". Today, it is a worldwide movement. At the NoVa event, students got the chance to learn from a person—a "human book"—instead of a library book.

    Patricia Cooper organized the event. She said that human books celebrate variety by telling their life stories in an easy-going setting. "The goal of the human library is to talk to people in your community who you may otherwise not speak to because you have your own prejudices (偏见) and hopefully to break down some of these barriers."

    This is the third year that NoVa has held such an event. The collection of human books included a civil rights activist, a scientist from the American space agency NASA, and an opera singer.

    Artist Brian Dailey was a human book. He spoke about his travels to 113 countries in seven years. Dailey said that, during his travels, he asked people whom he took pictures of for a one-word answer to a series of other words—such as love, freedom and war. He discovered that people in different countries often had very different reactions to the same word.

    When Dailey asked people in Africa about the word "war" they used words like justice, liberation and peace. When he asked the same question to people in Syrian refugee camps, the answer was: "tears, hunger, fear, destruction".
