Once there was a young boy. He had no family except for an old llama. Each day the boy and his llama walked many miles, looking for a home. Each night they curled up (赌缩）and slept. But on one starry (满天星斗的）evening, the old llama died. The boy buried (埋葬）his friend next to a small icy river. Then he sat under a tree and cried. What would he do? He had no family and no home.

The boy cried for a very long time. But there was no one to comfort (安慰）him. There were only the stars in the sky.

Suddenly, the sky filled with bright light. The boy held his breath. He was afraid to move. One bright star fell to the ground. Slowly, the star took the shape of the old llama. She bent her head and drank from the river. She looked at the boy and smiled. As she jumped back into the sky, bits of llama wool fell. As the sun began to rise, the boy picked up the soft, warm wool. It gave out light in his hands like starlight. He carried the wool to the city and sold it. With the money, he bought a house. He bought two young llamas. He never forgot the star llama. And he was never lonely again.

    There are three people in Yang Yang's family. They like different kinds of food. Yang Yang likes rice a lot. But she doesn't like chicken at all. Her father is from Shanxi. He doesn't like rice at all. He likes chicken and bread very much. Her mother is from Dalian. She doesn't like rice or bread at all. But she likes fish and vegetables a lot. They love each other and help each other.

    Humoody was born in Iraq. When he was two years old, his face was badly hurt and he couldn't see any more. He came to the United States to get medical care and now lives with an American family in Washington State.

    Humoody quickly learned to use a cane(手杖) to get around. He also started clicking(使发出咔哒声),sensing objects by listening for echoes (回声). To help Humoody develop this skill, his family found him an

echolocation(回声定位_) teacher, Juan Ruiz. Ruiz is also blind and he has been echolocating for many years." Even someone who's not blind can try it," he says. Stand facing a wall a couple of feet away. Make some noise by clicking or talking out loud. Listen carefully. Now walk a little closer to the wall and keep making your noise. Can you hear how it changes as the wall gets nearer?

    Experiment with how your voice or clicks sound in different parts of your home. "Every room has a different sound to it," Ruiz says.

    How does the sound of a kitchen or bathroom compare to the sound of a carpeted(铺有地毯的) room? What about a long hallway? The differences you hear are the same kinds of clues(线索) that blind people listen to. With lots of practice, their brains have learned to get information from these clues.

    Humoody has never let being blind slow him down. Learning how to echolocate is helping him get around more easily and safely, especially in places where he can't take his cane, like the football field.

    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.

    John went to spend his summer holiday in China with his parents last year. They visited some famous cities like Beijing, Guangzhou, Kunming and Shanghai. In Beijing he visited the Great Wall, Tian' anmen Square and the Palace Museum. They also went to the zoos and the parks. The weather was fine and cool. They had a good time in the parks. They also took lots of photos there. In Guangzhou, they visited some museums. They were very interesting but kind of crowded. In Kunming the weather is never too hot in summer. They visited the Stone Forest, the Golden Temple and EXPO Garden. They climbed the Xishan Mountain. In Shanghai they went to the beach and had great fun playing in the water.

    "It's very interesting to visit China and I learned a lot about Chinese history," John said. "

    If I have another chance, I'll come back to China again."

    Fred is a sports fan(迷). He likes all kinds of s ports games. He never plays football, but he knows much about it. When there is a football game on TV, he watches it. Sometimes he does not go to school.

    One day, there are two games on TV. One is at 8:00 in the morning, and the other begins at two in the afternoon. Fred decides to stay at home for the whole day.

    At 7:30, Fred's mother comes to Fred. She sees him still in bed.

    "Is there anything wrong with you?" she asks.

    "I am not feeling well," Fred answers.

    "Shall I take you to the doctor?" she asks.

    "No. Don't worry, Mum. I will be OK soon," says Fred.

"Then I'll go to work. My students are waiting for me," she says, "If you really feel bad, do call me. OK?"

    Fred's mother hurries out of the room. Now Fred gets out of his bed quickly.

    He turns on the TV and sits in front of it. How exciting (激动人心的 ) the game is! He forgets all about his lessons.

    To his surprise, his mother comes back for the key to her office.

    "Are you really ill?" she asks.

"Well, er … I'm all right now. Sports is good medicine (药),"Fred says.
