A terrible explosive noise was heard, immediately followed by strong shaking of the classroom building. Mrs. Li Lan, a country school teacher in Sichuan, who was giving a class, could hardly keep on her feet, and many of her pupils made panic cries. Mrs. Li realized at once that it must be a powerful earthquake hitting the area. Though she herself was scared, she managed (设法) to make the children calm down, opened the door right away and told the children to leave the classroom and get down to the playground as quickly as possible.

When all the children had left, she followed them to the first floor. The earth still kept moving violently (巨烈地). Some of the buildings nearby were falling down, and a great number of falling stones were rolling down from the hills behind the school. Suddenly, she found a little boy fell over and was hit by a big stone right on his body. She forgot the danger she was facing and ran over, trying to push the stone away. The stone was so big that it was not easy for her to move it. She kept pushing until the boy was pulled out, carrying him to the center of the playground. The boy was later sent to hospital and saved.

    Children across the world are taking pictures of their school meals. They are sending these pictures over the Internet to a young girl in Scotland. Then she shares the pictures and stories with people around the world.

    The girl's name is Martha. She likes to write. So Martha decided to start her own blog. Every day, Martha writes on the Internet about the meals she eats at school. She also takes pictures of the food.

    Martha is very honest about the food. She does not just describe the food. She judges (评价) the taste of the food. She also judges how healthy the food is. Sometimes she likes the food, and sometimes she does not. Now, other people send pictures to Martha. Students around the world share their pictures of their school food!

    Martha also started her blog for another important reason. She began to raise money for the organization (组织) Mary's Meals. Mary's Meals works in the East African country of Malawi . It provides food for children in schools. Martha encourages her readers to send money to Mary's Meals to help build a kitchen.

    Martha hoped to raise about 10,000 dollars. But the total reached 100,000 dollars and still keeps on growing!

    An old man walked slowly into a restaurant with his cane(拐杖).His old jacket and shoes made him unusual that day.

    A young waitress named Mary watched him move towards a table by the window.She ran over to him,and said with smile,“Here,sir.Let me give you a hand."

    Without saying a word,he gave her a smile. She pulled the chair out from the table and helped him sit down. Then she put his cane against the table where he could reach ithimself. In a soft, clear voice he said,"Thank you." "You're welome, sir," she replied. I'll be back in a moment, and if you need anything, just wave(挥手) at me!"

    After he had finished a good meal,Mary brought him the change. She handed him his cane, and walked to the front door. Holding the door open for him, she said,“Come back and see us, sir! ”The old man turned around and smiled.

    When Mary went to clean his table, she was shocked. Under the plate, she found a business card, a 100—dollar and a note.The note said.

    “Dear Mary, I respect you very much, and you respect yourself, too. It shows the way you treat others. You have found the secret of happiness."

    In fact,the old man was the owner of the restaurant. That was the first time that she, or any of his waitresses, had seen him.

    Gadot, an Israeli actress, was praised for showing Wonder Woman's power, as well as her kind heart. She helped to change how women see themselves.

    Gadot was born on April 30,1985. She was taught to be capable(能干的) and independent as she grew up in a small city in Israel. “There was no TV-watching. It was always 'Take a ball and go play'," she said. In her own words, she was a good girl as well as a tomboy.

    This attitude toward life encouraged Gadot to follow her heart when making future life choices. At 18, she got a chance to be a model. But she didn't think it was the right time for her to do this kind of work. Instead, she joined the army, starting her work at 5 a.m. every day. Then she studied law out of love for the field.

    Later, a director invited her to an audition(试镜), which led her to Wonder Woman. The movie took the world by a storm in 2017. She played a brave and strong female superhero, who enters the world of man to stop a war. Gadot was included(列为) on Time magazine's 2018 list of the 100 Most Influential People. She not only lit up the big screen, but also the lives of women all over the world.
