When most 8-year-old children are in school or playing, little Anna Wang from China is looking after her grandmother and great-grandmother.

    The family lives in a poor house in the remote mountains(偏远山区) of Huling, Rui'an. Her mother and father leave her when she is only 3 months old. She has a grandmother and a 92-year-old great-grandmother. Her grandmother is ill(生病的), so she can't look after herself. Anna cooks for them, and helps them with housework every day. Every morning, she gets up early and cooks breakfast for her family. She often cleans the house, and helps them to the toilet(厕所). She has no other family to help her.

    A neighbor(邻居), Lin Feng, with a farm usually gives Anna vegetables, and he helps her carry them to her home. Sometimes he even buys clothes for her and her family. Also Lin Feng teaches her to read and write.

    Little Anna says she does the housework happily because she wants to. She always says "I should be ready to help my family and other people because we should love everyone all over the world."

    Larry and Jo Ann were an ordinary couple. Like any other couple, they made efforts to make ends meet (收支相抵) and do the right thing for their children. They often argued about what was wrong with their marriage and who was to blame (责备). They wanted to make changes.

    "You know, Jo Ann, I've got a magic chest (衣柜) of drawers. Every time I open them, they're full of clean clothes," Larry said. "I want to thank you for filling them all these years."

    Jo Ann stared at her husband and felt strange. This wasn't the first time Larry had done something strange recently, so Jo Ann forgot it quickly. But it happened again a few days later.

    "Jo Ann, that was a great dinner," Larry said one evening. "I appreciate all you have done in the past 15 years. You have cooked lots of delicious food for me and the kids. "

    Jo Ann was growing worried. "What's wrong with my husband?" she wondered.

    Day in and day out, Larry continued his praise.

    Over the weeks, Jo Ann grew more used to her husband's unusual behavior. Her step was now a little lighter and she didn't seem to get upset as often.

    Larry has never told Jo Ann the reason for his change in behavior. So it will likely remain one of life's mysteries. But it's one I'm thankful to live with.

    You see, I am Jo Ann.

    When he was nine years old, American boy Milo Cress had a question: How many plastic straws(吸管) do Americans use every day?

    He quickly learned there wasn't a simple answer. The boy tried to work it out himself. Through lots of research, Cress found out that Americans use about 500 million straws every day. In hopes of reducing plastic waste, he founded the Be Straw Free project in 2011.

    Cress started the project in his hometown – Burlington, Vermont. He asked a local restaurant to stop offering straws with every drink order. It was a simple change. However, it would save money. And by doing that, the restaurant would cut down on its straw use by 50 percent.

    For the years that followed, Cress tried to spread his project across the United States. More and more restaurants agreed to join. They stop providing the customer with a straw unless he or she asks for one. Last April, Seattle became the first American city to completely ban (禁止) plastic straws.

    Plastic pollution has been one of the most serious problems today. According to scientists, more than eight million tons of plastic end up in the ocean each year. Plastic straws are especially terrible. They make it easy for people to get comfortable with single-use plastics.

    After his project became popular, Cress took his findings on the road. He has since spoken to tens of thousands of students around the world. He wants to encourage more people to say no to plastic straws.

    "Focusing(聚焦) on straws is one simple step we all could take," Cress says. "And it makes me feel that I, as a kid, could make a difference, too."

    Mandy Harvey is a 29-year-old singer from Florida. She lost most of her ability to hear when she was 18.

    Harvey became a singer in her teens. _________ But she decided to start singing after she learned how to feel a song's beat through the wooden floor of a stage or theater. She watches carefully to make sure her musical instruments are tuned correctly and she is singing in the correct pitch.

    Harvey is now a professional singer. But not many people in the United States had heard of her until Tuesday night. That changed when she appeared on the television show “America's Got Talent”The show has four judges who watch people perform and decide if they should continue in the competition.

    Harvey said, "I gave up singing after I lost my hearing. But I want to do more with my life than just give up." As she was singing, one camera cut away to capture images of people in the theater. Many were seen crying. At one point, everyone stood up and cheered. By Wednesday afternoon, a video of Harvey's performance had been played 46 million times.

    Why? Shortly after she finished singing, Simon Cowell, one of the judges, gave her a golden star into the air. That meant Harvey could move on to the final round of the talent competition. Cowell said," I've done this a long time, and that was one of the most amazing things I've ever seen and heard."

    Many people wrote online that Harvey's performance was encouraging, and they will not give up on anything they want to do, either.

    The Sixth Time I Went to the Principal's Office When I was in the seventh grade, I had problems behaving. My heart was in the right place, but I couldn't always follow the rules. I played many tricks on my schoolmates. Once, I even pulled a girl's hair on the school bus to get her attention. As a result, I was repeatedly sent to the office of the principal(校长).

    Although I hated going there, I did not hate the principal, Mr. Ratcliff. Mr. Ratcliff was a kind, elderly man. When he spanked(打屁股)me for putting some ants into a classmate's pencil box, it didn't hurt at all, but it did hurt my feelings. I thought so much of him and moments like that seemed to prove I was hopelessly bad.

    When I got called to Mr. Ratcliff's office for the sixth time, I had no idea what I had done. I felt disappointed as I walked down there. I went into his office, sat down, and looked at the floor. Then he said the last thing I expected to hear:"

    Kevin, I've heard you've been behaving really well lately. I want you to know how proud I am of you, and I just called you down to my office to give you a peppermint."

    "Really?" I was surprised.

    "Yes. Now you can take that peppermint and go back to class."

    I carried the peppermint with me as if it was a gold coin. When I got into my classroom, I bragged(吹嘘)to my classmates about my turnaround, excitedly. I wasn't so bad after all.

    Mr. Ratcliff was really kind. He made me realize that I was just a kid who had problems with behavior. He bought some peppermints and took the time to notice me when I got something-anything-right. Mr. Ratcliff gave me some hope by giving me some love. I will just remember him for the rest of my life.
