    John was a very strong man. Once he got a job of cutting wood in a forest. His boss gave him an axe(斧子) and showed him the area where he should work.

    The first day, John cut down 18 trees. "Good," the boss said, "keep it up!" John was encouraged by the words of the boss and tried harder the next day, but he could only cut down 15 trees. The third day he tried even harder, but he could only cut down 10 trees. Day after day he was cutting down fewer and fewer trees.

    "I must be losing my strength," John thought. He went to the boss and said that he could not understand what was going on. "When was the last time you had sharpened(使锋利) your axe?" the boss asked. "Sharpened? I had no time to do it. I have been very busy trying to cut more trees." said John.

    While John was working hard, he didn't think about how to do his job better.

    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.

    The mystery(悬疑) stories of Sir Arthur Conan Doyle are famous all over the world.

    The detective in his stories is called Sherlock Holmes. He solves mysteries in a most surprising way. Through it all, his assistant, Dr Watson, watches with admiration(钦佩). Watson then writes up the story of the mystery afterwards.

    This is a useful story writing skill. Because Watson is not very clever, the story remains a mystery until the end. The readers can sometimes pick up some clues before he does! Then, to make Watson understand the mystery, Holmes has to explain it all, step by step. So we, the readers, get to see it step by step too. Watson is almost as good a character in the story as Sherlock Holmes!

    The very first time they meet, Holmes greatly surprises Watson. When they are first introduced, Holmes says to Watson, "How do you do? I see you have been to Afghanistan.”

    Watson is too amazed by this to ask Holmes how he knows this. Watson has, indeed, been to Afghanistan. Later, he asks Holmes about it. Holmes explains that there is nothing magical about what he does. He gets to know it all by very, very careful observation (观察).

Observation One

    Watson was introduced to Holmes as a doctor. Yet Holmes thought that the way he stood and walked made him seem like a soldier. So, this meant he was probably an army doctor.

Observation Two

    Watson's face was quite dark skinned. But his wrists(手腕) were pale. So his dark face was probably sunburnt. This meant that he had been to a hot, sunny country. As he was a working doctor, this was not a holiday. He must have gone with the army.

Observation Three

    At the time, the British army had soldiers at bases in many parts of the world. So there were still a lot of places to choose from. However, Holmes saw that Watson looked very tired and he was always holding his left arm, as if it was painful. So, he had probably been with the army to a place where they were fighting. There was only one place where the British army was fighting at that time: Afghanistan.

    Jan Mela was born in Poland and he lost an arm and a leg in an accident in 2002. But that didn't stop him. The 15-year-old boy from Poland walked to the North Pole(北极) in 2004.

     "If I can do it, other people can do great things, too," Mela said before he went. Polish newspaper said Mela was the youngest person and the first disable(残疾) person to walk to the North Pole. Mela walked to the North Pole with the help of a man-made leg.

    After the accident, Mala felt sad for himself. But he didn't lose hope. One day, he met Marek Kaminski. In 1996, Kaminski went to the North Pole and the South Pole in the same year. Mela wanted to see the North Pole, too. So Mela asked Kaminski if they could go together the next time. Kaminski said yes.

    It took Mela twenty-one days to get to the North Pole. The last three or four days were really hard because of the bad weather. But Mela didn't give up going.
