There are many people on the bus. Some have seats, but some have to stand. At a bus stop, a woman gets on the bus. An old man hears the door and tries to stand up.

    "Oh, no, thank you," the woman forces(强迫)him back to the seat. "Please don't do that. I can stand.''

    "But, madam, let me……" says the man.

    "I ask you to keep your seat." the woman says. She put s her hands on the old man's shoulder.

    But the man still tries to stand up, "Madam, will you please let me……" "Oh, no." says the woman. She again forces the man back.

    At last the old man shouts(喊), "I want to get off the bus!"

    Gary and Gavin were twin brothers who worked in a store owned by their father. After the father had passed away, they took over the store. One day, Gary left the bill on the cash register (收银台), but when he returned, the money was gone.

    Gary then asked his brother," did you see that twenty-dollar bill on the cash register?" Gavin said no. But Gary did not let it go and kept asking. That made Gavin very angry and they quarreled with one another. The quarrel divided the young men. Later, a wall was built in the center of the store. For twenty years, hostility (敌意) never ended.

    One day, a strange man came to the store. He walked in and asked Gary, "How long have you been here?" Gary replied that he'd been there all his life. "Then you are the person I'm looking for," the man said. "Twenty years ago, I was totally broke and hungry. I entered this store from the back door and saw a twenty-dollar bill on the cash register. And I took it. All these years I haven't been able to forget that. I had to come back and apologize for that."

    The stranger felt shocked when seeing tears well up in the eyes of the middle-aged man in front of him. "Would you please go next door and tell the same story to the man in the store?" Gary asked. Then something surprised the stranger even more-after hearing his story, the two middle-aged men hugged each other. After twenty years, the wall that separated them finally came down.

    National medals(奖章) and honorary titles(荣誉称号) are usually awarded once every five years. As part of the celebration of the 70th anniversary(周年) of the founding of the People's Republic of China (PRC), President Xi Jinping awarded forty-two people the Medal of the Republic, the Friendship Medal and national honorary titles. They come from different backgrounds, including scientists, lawmakers, educators, artists, model workers and six non-Chinese people. All have made big contributions(贡献) to the nation's construction and development. Here are some of the people we'll know.

    Chinese scientist Tu Youyou is one of the eight who were awarded the Medal of the Republic. Tu, who won the 2015 Nobel Prize for her discovery of the malaria drug artemisinin (抗疟药物青蒿素), is the first Chinese citizen to win a Nobel Prize in Physiology or Medicine. She has saved millions of lives worldwide. She has also made important scientific innovations(创新) in traditional Chinese medicine.

    Tu is not the only one who has given her life to the country's development. Nan Rendong, before his death in 2017, led the research and development of China's Five-hundred-meter Aperture Spherical Telescope (FAST, 500米口径球面射电望远镜), the world's largest radio telescope. He worked on the project for more than 20 years. His contributions to Chinese astronomy (天文) earned him the title, "the people's scientist".

    Also receiving awards are six foreign friends who have lent their hands to assist with China. Former French Prime Minister(总理) Jean-Pierre Raffarin, one member of the Friendship Medal, is a supporter of the Belt and Road Initiative(一带一路倡议). Having worked to strengthen the friendship between French and Chinese people in the past few years, he is "sincerely pleased" with the honor. "To work for this friendship is to work for peace," Raffarin said.

    Thanks to the great efforts made by these great people, we can live in a peaceful country.

    Boyan Slat has one huge goal. It's a goal that could be good for people and a {#blank#}1{#/blank#} all over the world. Amazingly, it looks like he's going to m {#blank#}2{#/blank#}his goal.

    When he was 16  Dutch engineering student Slat was on vacation in Greece, and he started to think about all the rubbish that is p{#blank#}3{#/blank#} onto beaches by water. The oceans around the world are all of plastic—millions of tons of plastic. Unfortunately, plastic doesn't just disappear. It takes c{#blank#}4{#/blank#} to break down (分解).

    The p{#blank#}5{#/blank#} situation of the oceans is bad and worrying and Slat wanted to do something to change it. So he made it a personal goal to clean up the rubbish in the world's oceans.

    Slat started with an idea for an unusual m{#blank#}6{#/blank#} to "catch" the plastic floating (漂浮) in the water using the natural energy of the ocean. He left school in 2013 to begin work on his project The Ocean Cleanup. Soon, the project r{#blank#}7{#/blank#} a lot of attention.

    A year later, he was leading a team of 100 scientists and engineers working on the invention. Slat needed money for this, so he started asking people to d{#blank#}8{#/blank#} to his project online and raised over $ 2 million!

    Soon after, Slat was named a "Champion of the Earth" by the United Nations for his meaningful and v{#blank#}9{#/blank#} work. It's the most important title the UN gives to people helping the environment. The Ocean Cleanup also won several awards (奖项) for having one of the best inventions of 2015. But the d{#blank#}10{#/blank#} goes on for Slat. He hopes that the oceans will be free of plastic in about twenty or thirty years.
