A lot of boys and girls in western countries are wearing the same kind of clothes, and many of them have long hair, so it is often difficult to tell whether they are boys or girls.

    One day an old man went for a walk in a park in Washington and when he was tired, he sat down on a chair by a swimming pool. A young person was standing on the other side of the pool.

    "Oh!" the old man said to the person sitting next to him. "Do you see the person with the loose clothes and long hair? Is it a boy or a girl?"

    "A girl," said his neighbor. "She is my daughter."

    "Oh!" the old man said quickly. "Please forgive me. I didn't know that you were her mother."

    "I'm not," said the person. "I'm her father."

    Fifteen hours is a long time to be on a plane, but you know, Africa is a long way from America. Finally, we're in Namibia, a country in southwest Africa. Namibia is about one size of California. However, it is home to just over two million people. And the country's main airport is 45 kilometers east of its capital, Windhoek.

    Now we are in a wildlife park. We will spend five days finding ways to protect this area's wildlife. At the moment, my wife and our two kids are enjoying some local dishes. I'm talking with workers in this park. I'm so much looking forward to the following days!

    Yesterday morning, I had nothing to do. So I went to visit the Eiffel Tower, a symbol of Paris. It was my first time there, so I took a lot of photos.

    Finally, the big moment came! A lot of artists came to watch my show. It was a great success. After the show, I attended a big party. It was great, but I felt so sleepy after it.

    When I got back to my hotel, it was already1:15 am. I went to bed without washing. I just needed a good rest before my two—hour journey home by plane.

    Tom Longboat had always been fast. He learned to run as a young boy on the Six Nations Grand River Reserve in Ontario, Canada. He ran a long distance each day to get to school or to visit his family and friends.

    Sometimes running was the easiest part of Tom Longboat's life. As an aboriginal(土著的) athlete, life was hard for him. Other people tried to control how he trained and where he raced. But he chose to depend on his own spirit, mind and body, and would never back down.

    Tom Longboat won the Boston-Marathon in 1907 with a time of 2 hours, 24 minutes and 24 seconds, 4 minutes and 59 seconds faster than the world record(纪录) at that time. The Boston newspaper said he was the most excellent runner who had sped over their roads.

    He took part in the Olympics and won many international marathons.

    His spirit lives on. Every year, the best aboriginal athlete in Canada is given the Tom Longboat Award.

    We go to school every day to become better people. How can we start to make big changes in our lives? Perhaps we can get tips from former US First Lady Michelle Obama. During a visit to China from March 20 to 26 in 2015, Obama shared her views on education and youth empowerment with students.

    The first lady encouraged Chinese students to aim high and get a good education. At Chengdu No 7 High School, she told students that having humble roots doesn't matter as long as you have perseverance (毅力). Obama said her family was not rich. Like many Chinese students, her parents had big dreams for her. She felt the weight of her parents' sacrifices (牺牲) on her shoulders and worked hard to make them proud. Persevering was not easy, though. Sometimes she had to wake up at 4:30 am and study late into the night. "But whenever I got tired or discouraged… I would remember something my mother always told me. She said: A good education is something that no one can take away from you.'"

    Mrs Obama also encouraged Chinese students to study abroad to broaden their horizons (开阔视野) in a speech at Peking University. "As the Chinese saying goes: It is better to travel 10,000 miles than to read 10,000 books," she said. It's not enough to get good grades in school. It's also important to have real experience with languages, cultures and societies that are different from your own, she noted. Studying overseas can also benefit future international relations. It can help young people from different countries work together to deal with shared problems like climate change, Obama said.

    Nowadays we can see more and more electric bikes in the street. Electric bikes 61. {#blank#}1{#/blank#} (be) easy to ride. They run fast and make no {#blank#}2{#/blank#} (pollute). They become very popular, {#blank#}3{#/blank#}the electric bikes also cause more traffic accidents. So China plans {#blank#}4{#/blank#} (make) a new rule for the electric bike riders. If an electric bike is {#blank#}5{#/blank#} (heavy) than 40 kilos and can go faster than 20 kilometers an hour, its rider must get a license. It means some riders have to pass driving tests before they ride {#blank#}6{#/blank#} (them) electric bikes on the road.

    People have different ideas after {#blank#}7{#/blank#} (hear) the plan. Some welcome the plan. A bus driver said happily, " {#blank#}8{#/blank#}a good plan! I think it will make the street much safer." Some are not happy with the new rules at all. One rider said {#blank#}9{#/blank#} (sad), "I don't want to get a license. It's not convenient {#blank#}10{#/blank#}me to get one." Some don't care about it. A young rider said calmly, "I prefer to use shared bikes which are popular in many big cities of China now. I hope they can come to Loudi earlier!"
