People say that one person can't really make a difference, but I don't believe that. If all of us just do "one" thing like the following three heroes, we will make a difference.

Super Girl

    When she was 7, Brooklyn Wright wrote The Adventures of the Earth Saver Girl. In the book, a girl learns she has the power to make the Earth free from rubbish. She calls her Super Girl and tries her best to save the Earth. Brooklyn Wright has visited more than100 schools to teach students about pollution. Last year, she received a Gloria Barron Prize for Young Heroes for her work.

A Voice for Elephants

    Many elephants are being killed for their ivory. After learning the facts, China's Celia Ho, 14, decided to take action. By making posters and writing letters to newspapers, she hopes more people will learn about the problem.

Turning Cooking Oil into Fuel

    Jane Lin didn't start out "to be green" .At first, she was worried about her neighbor who couldn't afford heat in winter. At a science expo, she saw someone turning old cooking oil into fuel. Suddenly, she came up with a plan to collect old cooking oil for the poor family. So far she has collected about 21, 000 gallons of fuel for 210 families. At the same time, she helps reduce the emission（排放） of CO₂  and other greenhouse gases.

    Once upon a time there was an old man. He was really good at fishing. One day, he was fishing on the bank of a river. Soon he caught a full basket of fish. Just at that time, a child came and said to him, "Can you give me the fishing rod(钓鱼竿) in your hands? The old man looked up at him and said, "I can give you a full basket of fish." But the child shook his head. The old man was surprised and asked, "Why do you want the rod instead of the fish?"

    "Oh! You know it doesn't take long to eat all the fish in a basket. But if I have the fishing rod, I can go fishing by myself and I won't be afraid of not having any fish to eat."

    You may certainly think that the child is very smart. Wrong! If he doesn't know how to fish, he cannot eat any fish, even if he has the fishing rod. It's useless to only have a fishing rod. Fishing skills are more important than the fishing rod.

    Too many people think that if they have "a fishing rod" in their life, they will no longer fear the wind and rain. In fact they will make the same mistake like the child in the story.

    For most of us, the idea of giving up our jobs to travel around the world seems impossible. However, one young couple has made it come true. What's more, they're getting a lot of money. How can they do this?

    While traveling in Fiji in 2016, Jack Morris, 26, met his girlfriend Lauran Bullen. After that, they began to travel around the world together.

    Now the two have become Internet stars with nearly three million followers from 45 different countries. To everyone's surprise, a simple photo taken during their trips can easily bring them thousands of dollars.

    Talking in his blog Do You Travel, Jack shared many stories behind their wonderful photos. He said that they were used to taking photos at a certain time.

    "Most of the time we like to take photos around one hour after sunrise. At this time of day, most places of interest aren't so busy," Jack wrote. He also said that they never dressed up their photos and tried to keep what they were like." People prefer a true life, I believe. "

    Now the couple live in Bail. They are always posting inspirational(灵感的)photos to the Internet. At the same time, they are planning to visit one new country each month.

    When scientist Jessica Wade realized how hard it was to find information about women scientists, she decided to help solve that problem. She has now added the stories of over 300 female scientists to Wikipedia.

    Dr. Wade has always been interested in science. But as she kept going in science and learned more about amazing women scientists, she was surprised to learn that they didn't have Wikipedia pages.

    Wikipedia is the world's largest encyclopedia, and the world's 5th most popular website. What makes it special is that anybody can add to or change it. But even though Wikipedia has close to 6 million articles. Dr. Wade noticed that "It doesn't have the stories of many amazing women in science." She says that 83% of the biographies on Wikipedia are about men.

    So, in January. 2018 she decided to write one Wikipedia article about a female scientist every day. She doesn't get paid, but it has become her second job. So far, she has created 306 Wikipedia pages.

    Dr. Wade will keep writing her articles, but she also wants to teach other people how to add articles to Wikipedia. She would like to create a website to keep track of all of the biographies. She wants to turn them into a teaching tool.

    "With one more world championship, I can apply for the Guinness World Records (吉尼斯世界纪录), "said Chen Yongning, a 93-year old ping pong lover in Chengdu, capital of southwest China's Sichuan Province, Red Star News reported on April 2^nd, 2019. With 80 years of experience and a racket that he bought from a stationery shop for 15 yuan, Chen won World Veteran Championships in 2016 and 2018.

    "I'm not tired. I play with my hands and arms, and my feet don't move," said Chen after playing ping pong for 40 minutes with a younger player Ye. "Chen is physically strong. He can usually play several games with us," said Ye, explaining that Chen is energetic, though he is troubled by backache.

    Chen started to play ping pong when he was 13 years old. While he was playing with friends in his school playground, the headmaster saw Chen very carefully follow the rules of a game he was playing, while the other children tried to play tricks on each other. The headmaster called him over, gave him a ball and rackets, and asked Chen to play with him. Chen didn't know how to play ping pong at that time, so he just followed the headmaster's lead. Ever since that moment, Chen said, he had fallen in love with it.

    As he grew up, Chen worked in Shanxi Agricultural College (now Shanxi Agricultural University), where there were excellent ping pong facilities. He sharpened his skills and took part in various competitions in his spare time, winning a number of local medals.

    Chen has a son and a daughter. Both of them love their father and are successful in their own fields. One of them will go with Chen to the 20th World Veteran Championships which will be held in France next year.

    Chen has already decided he won't stop playing ping pong unless he is 100 years old.

Does Fame Drive You Crazy

    Although being famous might sound like a dream comes true, today s stars, feeling like zoo animals, face pressures that few of us can imagine. They are at the center of much of the world's attention. Paparazzi (狗仔队) camp outside their homes, cameras ready. Tabloids (小报) publish thrilling stories about their personal lives. Just imagine not being able to do anything without being photographed or interrupted for a signature (签名)!

    According to psychologist Christina Villarreal, celebrities—famous people—worry constantly (不断地) about their public appearance. Eventually, they start to lose track of who they really are, seeing themselves the way their fans imagine them, not as the people they were before everyone knew their names. "Over time," Villarreal says, "they feel separated and alone."

    The phenomenon (现象) of tracking celebrities has been around for ages. In the 4th century B. C, painters followed Alexander the Great into battle, hoping to picture his victories for his admirers. When Charles Dickens visited America in the 19th century, his works attracted thousands of fans, leading him to complain about his lack of privacy. Tabloids of the 1920s ran articles about film—stars in much the same way that modern websites do.

    Being famous people today, however, is a lot more difficult than it used to be. Superstars cannot move about without worrying about photographers with modern cameras. When they say something silly or do something ridiculous, there is always the Internet to spread the news in minutes and keep their "story" alive forever.

    If fame is so troublesome, why aren't all celebrities running away from it? The answer is there are still ways to deal with it. Some stars stay calm by surrounding themselves with trusted friends and family or by escaping away from big cities. They focus not on how famous they are but on what they love to do or whatever made them famous in the first place.

    Sometimes a few celebrities can get a little justice. Still, even stars who enjoy full justice often complain about how hard their lives are. They are tired of being famous already.
