Look at the light and beautiful snowflakes (雪花) falling. Ever wanted to hold them in your hands? They are always lost when they meet your hands.

    Well, this isn't just a problem for you. It was a problem for Wilson Bentley, too. In the 1870s, Wilson Bentley was just a teenager. His family lived in a small town in northeast America. Winters there were long and hard. Bentley's mother was once a school teacher. She taught him at home. Bentley didn't go to school until he was 14. He was a quiet boy, and loved reading his mother's books. But he was interested in his mother's microscope (显微镜). When the other boys were playing with balls, little Bentley was studying things like drops of water, flowers and snowflakes.     

    Bentley loved watching snowflakes. For the next two years, young Bentley spent many winter days in a cold room watching these ice crystals (晶体) under his microscope. The boy thought they were beautiful enough for him to start to draw pictures of them. But there were so many snowflakes that he couldn't draw them all.

    How could he keep their beauty all the time? Bentley thought of buying a camera.

    The boy and his mother asked his father to buy one. But, his father didn't agree. He thought the whole thing was a bad idea. He thought the only thing a farmer should do was farming.

    But finally Bentley did get a camera. For more than a year he tried to take pictures of snowflakes. On January 15, 1885, during a snowstorm, Bentley took the first ever photo of an ice crystal with his camera. “It was the greatest moment of my life,” Bentley said later.

    For 13 years, Bentley worked quietly and took thousands of photos of ice crystals. Later he became famous as “Snowflake” Bentley.

    The ocean is no longer a safe place for many creatures. For many years, 1 activities such as polluting and overfishing(过度捕捞) have made it 2 for many creatures to live in it. In 2015, Chile, a country in South America, tried to 3 that. It created the Nazca-Desventuradas Marine Park. It is the 4 ocean reserve in North or South America. It is about 115,000 square miles of the Pacific Ocean. That's about the 5 of the state of Arizona, USA.

    No 6 or any other kind of harmful human activity will be 7 in the waters in that area. That's good news for the sea creatures that live in that part of the Pacific Ocean. The area is 8 to many unusual creatures not found anywhere else in the world.

    2015 was a big year for protecting the world's oceans. In total, more than one million square miles of ocean were 9 protected in the year.

    Liesbeth van der Meer is a scientist at Oceana, a group working to 10 the oceans. She said Chile's new reserve was a great victory(胜利) for the world's oceans.

    "Mom, I'm bored," said Jason. "There is nothing to do." "You can clean your room," said Mom. "That's not fun." It was only the second week of summer vacation. It was still too chilly to go to the pool, and Jason was tired of watching TV. His friends went on a trip, and even his dog, Riley, was being lazy.

    Mom was getting ready to go downtown to the food kitchen to help out. She volunteered three times a week serving lunch to people that weren't as lucky as Jason. "Why don't you come with me to the food kitchen and help out?" Mom asked. "I don't know anything about working at a food kitchen," said Jason. "You just watch me, and then you will see how to serve the food," said Mom.

    It was time to go, and Jason was excited to try working in the food kitchen. He watched his mom put some chicken on a plate and some mashed potatoes. She then passed the plate to the next lady, and she put some green beans and bread on the plate. "I can do that," thought Jason. One of the volunteers left early, so Jason took his place in the serving line. He was in charge of putting salad on the plates. He served twenty-five people that day. After the kitchen closed, Jason and his mom stayed to clean up. "That was great!" said Jason.

    Jason was so excited and really enjoyed his day at the food kitchen. He couldn't wait to get home and tell his dad about how much fun he had. "Not only did it give me something to do, but I felt so good doing it," Jason told his dad. "Jason, that was nice thing you did today," said Dad. "You helped many people who aren't as lucky as you to have a hot meal," Mom said. "I am so proud of you, Jason! You worked very hard.

    Jason went to bed that night thinking about the food kitchen. "I am going to help out again," he thought. Jason made some new friends, and he didn't even know they lived so close to him in town! The best part was how good Jason felt inside.

Albert Einstein was a world famous scientist. He was born in Germany and later lived in America. He was best known for his theory of relativity（相对论）. This theory changed the way we understand space and time. Einstein had wild hair and always looked deep in thought. He always reminded us to keep asking questions.

One day, a young man asked Albert Einstein what the secret of success was. The scientist told him that the secret of success was hard work. A few days later the young man asked the same question again. Einstein was very "annoved". He did not say anything, but wrote a few words on a piece of paper. On the paper it was written: A=X+Y+Z.

"What does this mean?" asked the young man.

"‘A' means success." explained the old scientist. "‘X'stands for hard work, ‘Y' forgood method（方法）and ‘Z' means stop talking and get down to work."
