My daughter Kelly is a cautious person. She needs to warm up to situations, and is hesitant(犹豫的) to try new things. When with close friends, she becomes a leader who laughs loudly and chants. But when that comfort zone is not around her, she is shy and nervous.

    This has been challenging for me at times. “Shy” is not a word that I think has ever been used to describe me. But this has been a year of firsts for my girl that has filled her with a new sense of confidence. This year she moved to lap lane (习泳区） in swimming where she was preparing for a swim team. This year she learned to ride a bike without training wheels. And this year she completed her first kids' triathlon (三项全能).

    On Saturday, with a thunderstorm coming soon and my son's birthday party later in the day, we all went out in the dark of the morning for Kelly to participate in her first triathlon. We practiced transitions from swim to bike to run with her, we got all the equipment she'd need, and we kept talking about the race. But as we waited the two hours for the older kids to finish before her turn, she held my leg a little harder and told me she loved me a few too many times. She was nervous but trying to keep it together.

    And then it was her turn. From the second she jumped into the water, my heart soared. My daughter transformed into the most confident human being I had ever seen. She dominated （主宰） that swim, crushed that bike ride and ran to the finish with the biggest smile on her face.

    I can honestly say that I never felt so proud of someone in my entire life. It wasn't because she did a sport or anything like that. It was because she was afraid of something and conquered that fear with confidence and a fire I hadn't seen before.

    All day I would find myself just looking over at her and smiling. She might be wearing the finalist medal but I felt like I won that day. I won the chance to see my girl shine.

    Shine on, sweet baby.

    I grew up poor. We had little money, but plenty of love and attention. I understood that no matter how poor a person was, he could still afford a dream. My dream was athletics.

    By the time I was sixteen, I was good at baseball and football. My high-school coach was Ollie Jarvis. He not only believed in me, but taught me the difference between having a dream and showing conviction(信念).

    One summer a friend recommended me for a summer job. This meant a chance for money in my pocket — cash for dates with girls, certainly, money for a new bike and new clothes, and the start of savings for a house for my mother.

Then I realized I would have to give up summer baseball to handle the work schedule, and that meant I would have to tell Coach Jarvis I wouldn't be playing. I was dreading(害怕) this, but my mother said, "If you make your bed, you have to lie in it."

When I told Coach Jarvis, he was as mad as I expected him to be. "Your playing days are limited. You can't afford to waste them," he said.

    I stood before him with my head hanging, trying to think of the words that would explain to him why I dreamed of buying my mom a house.

"How much are you going to make at this job, son?" he demanded.

"Three twenty-five an hour," I replied.

"Well," he asked, "is $3.25 an hour the price of a dream?"

    That question laid bare for me the difference between wanting something right now and having a goal. I devoted myself to sports that summer, and within the year I was drafted by the Pittsburgh Pirates to play rookie-league ball, and offered a $20,000 contract. I signed with the Denver Broncos in 1984 for $1.7 million, and bought my mother the house of my dream.

    A new study suggests climate conditions in the Sahara Desert, one of hottest, driest and most deserted areas in the world, have changed from wet to dry a about every 20,000 years.

    But previous evidence has suggested the Sahara did not always experience such extreme heat and dry conditions. At times, the Sahara Ranged to a very wet climate. This permitted plants and animals to develop and grow and led to the creation of human settlements. Now, they have discovered more evidence, which, the lead researcher David Mc Gee says, supports the idea that the Sahara's climate kept changing between wet and dry about every 20,000, years.

    McGee reported these climate changes were mainly driven by changes in the Earth's(地轴)as the planet travels round the sun .This process affects the amount of sunlight between seasons. Every 20,000 years the Earth receives more strong summer sunlight. When the Earth's axis changes again, the amount of sunlight is reduced. This season change happened continuously every 20,000 years. The other part of the season produced rainy conditions, resulting in a wetter, greener, plant-rich environment. When the rainy activity weakens, the climate becomes hot and dry, like the Sahara remains today.

    The scientists based their research on dust collected from ocean sediment(沉积物)in the Atlantic Ocean bottom off the coast of West Africa. The dust contained layers (层)of ancient sediment built up over millions of years. Each layer could contain traces of Saharan dust as well as the remains of life forms. This information was used to assess over what time period the dust had built up. This led to the overall finding that the Saharan changes from wet to dry climates happened every 20,000 years.

David McGee said that today we only see the Sahara Desert as an extremely deserted and "inhospitable" place. The new study suggests that the area's climate has changes between grasslands and a much wetter environment, and back to dry climates, even over the last quarter million years. McGee says he thinks the latest research can be valuable in studying the Sahara's history as it relates to human settlement.

    A mixture of deep sorrow and anger has swept Brazilians across the country — particularly in the city of Rio de Janeiro — with the burning of their beloved Museu Nacional, or National Museum.

    By Monday morning, when I visited the site, the firemen were busy trying to enter the huge, early 19th-century neoclassical building. For all we know, everything may have been burned to ashes. Fortunately, no one, not even the four security guards who witnessed the beginning of the fire, has been injured.

    Nobody yet knows the cause of the fire, but it is the officials' irresponsibility and the funding shortages in particular, which are being blamed for this tragedy.

    Some of the museum's researchers told the press that they had been able to save some things from the exhibition rooms before the fire moved in. However, we Brazilians have lost much of the material memory of our short past. A good part of our 518 years of history, or that which had been transformed into storable objects, disappeared in just a few hours.

    The people of Rio de Janeiro were fond of taking their children  or grandchildren to the museum to show off their knowledge of the odd-looking mummies brought in from Egypt by the Emperor Dom Pedro II, a huge skeleton of a humpback whale, or the brightly coloured feathers of a headdress of the Kayapo tribe.

    When I think that I can no longer take my youngest daughter to the Museu Nacional — that is what gets me emotional. It is this feeling that has penetrated (穿透) our souls and may leave Brazilians feeling empty for a long time to come.

5 books I loved in 2018

By Bill Gates

    A great read is the perfect gift and I think everyone could use a few more books in their lives. My book list covers various topics, including an autobiography on learning throughout a life, a deep search on autonomous weapons (武器), a thriller about the fall of a once­promising company and a guide about meditation (冥想)­there's something for everyone.

    The Head space Guide to Meditation and Mindfulness, by Andy Puddicombe. The book starts with Puddicombe's personal journey from a university student to a Buddhist monk and then becomes an entertaining explainer on how to meditate. If you're thinking about trying mindfulness, this is the perfect introduction.

    Army of None, by Paul Scharre. It's an extremely complicated topic, but Scharre offers clear explanations and presents both the advantages and disadvantages of machine­driven warfare. His fluency with the subject should come as no surprise: he's an ex­soldier who helped draw up the U.S. government's policy on autonomous weapons.

    Bad Blood, by John Carreyrou. Carreyrou gives you the definitive insider's look at the rise and fall of a company. I found myself unable to put it down once I started. This book has everything: magazine cover stories, ruined family relationships, and the failure of a company once valued at nearly $10 billion.

    21 Lessons for the 21st Century, by Yuval Noah Harari. I'm a big fan of everything Harari has written, and his latest is no exception. If 2018 has left you stressed out by the state of the world, 21 Lessons offers a helpful framework for processing the news and thinking about the challenges we face.

    Educated, by Tara West over. Tara never went to school or visited a doctor until she left home at 17. I loved this life story of a young woman whose thirst for learning was so strong that she ended up getting a P.h.D. from Cambridge University.
