Billy's favorite color is orange. But he can't see what orange looks like. Billy is blind.

    A month after he was born, his mother noticed that his eyes weren't quite as big as a normal baby's. “Billy would never be able to see.” the doctor told his mother. After that Billy's mother began talking to him, describing things she saw outside the window. She described everything to him.

    Billy does not only depend on his mother's descriptions to learn about the world around him. He sees with his cars and his hands, too. He has perfect hearing. When people make phone calls, he can tell the numbers they dial(拨).

    Billy loves computer science. He began teaching himself computer programming when he was just seven years old. His dream school would be Stanford University. He gets top grades in his classes, making that a real possibility.

    “You can't let excuses get in the way of your dreams, and if you do that you can't move forward and reach your goals, “said Billy.

    On March 14, one of science's brightest stars went dark. Stephen Hawking, the world-famous British scientist, died at 78 in Cambridge, UK.

    Hawking is considered by many to be the greatest scientist in history since Albert Einstein. He came up with the theory（理论） that the universe (宇宙) began with the Big Bang and will end in black holes. His theories became the base for a lot of later research. He also wrote books to help common people understand the universe. His most famous book is A Brief History of Time, which has sold more than 10 million copies around the world.

    Besides his scientific achievements, Hawking was also someone who had a strong will. When he was 21, he got a serious illness that stopped him from walking and talking. Later in life, he had to sit in a wheelchair and “speak” using a computerized voice. But this didn't stop him from living a meaningful and colorful life.

    He celebrated his 60th birthday by going up in a hot-air balloon; when he was 65, he took part in a zero-gravity (零重力) flight to experience weightlessness. He hoped to travel into space one day. In 2015, Hawking spoke about how he felt life was unfair when he first knew about his illness. “But now, 50 years later, I can be quietly satisfied with my life,” he said.

    Mr Brown is a famous doctor. He lives in Sydney with his wife and three children. His wife's father, Mr Black, lives with them too.

    Mr Black is too old to work and he always sits in his chair near the bed all day; but in spring, if the weather is nice, he will sit outside. Sometimes, he even takes his chair into the garden if it is warm enough.

    Recently, Mr Brown found that spending more than three hours playing outside every day can reduce a child's risk of becoming short-sighted. It challenges the people's belief that short-sightedness is caused by using electronic products or reading in weak light. Many people come to see Mr Brown and ask him why Mr Brown shows his research and believes that natural light has a special chemical which stops the eyeball from growing out of shape and prevents people from becoming short-sighted.

    Mr Brown's oldest son, Andersen Brown, is twenty-seven. He is also a doctor like his father. He agrees with his father's idea and he suggests that everyone should spend some time outside. It doesn't matter that time is spent in travelling, playing sports outside or just sitting outside like his grandfather.

    Mr Brown's oldest daughter, Wendy Brown, is twenty-four. She is a music teacher. She teaches students in a junior high school. She likes teaching very much. She thinks those teenagers are very lovely.

    Mr Brown's youngest son, Mike Brown, is not old enough to go to work. He still goes to school. He is a very clever and hard-working boy. He is good at studying. He wants to be a scientist when he grows up.

    I was driving after school on Monday from Dublin to Drogheda and on my way home, I saw a wallet lying on the roadside. I thought the wallet must belong to the driver in front of me, because he had smoked there. I sounded the horn twice but he didn't hear. So I stopped and picked up the wallet. I checked the wallet to see if I could get any phone number to call. I found and called two numbers but I was told they were wrong numbers.

    Later, I found a driving license and decided to drive to his house in Termonfeckin according to the address on the license. It is a 30-minute drive away from Drogheda. When I got to his house, I saw his wife and the first thing she asked was if I had found a wallet. I started smiling and said yes. The lady was really happy and called her husband. He ran to us at the gate and welcomed me to their house. After giving the wallet to him, he checked to see whether everything was inside. They offered me 20 dollars for gasoline(汽油) but I refused.
