Hundreds of years ago, news was carried from place to place by people on foot or by horse. It took days, weeks and sometimes months for people to receive news. Now it is possible to send words and pictures around the world in seconds. Billions of people learn about news stories of their own country and all over the world every day, either by watching TV or reading newspapers.

    Newspapers have been an important part of everyday life since the 18th century. Many countries have hundreds of different newspapers. How do newspaper editors decide which news stories to print? Why do they print some stories and not others? What makes a good newspaper story?

    Firstly, it is important to report new stories. TV stations can report news much faster than newspapers. Yet, newspapers give more about the same story. They may also look at the story in another way, or they may print completely different stories to those on TV.

    Secondly, a news story has to be interesting and unusual. People don't want to read stories about everyday life as a result, many stories are about some kind of danger and seem to be "bad" news. For example, newspapers never print stories about planes landing safely, instead they print stories about plane accidents.

    Another factor (因素) is also very important in many news stories. Many people are interested in news in foreign countries, but more prefer to read stories about people, places and events in their own country. So the stories on the front page in Chinese newspapers are usually very different from the ones in British, French and American newspapers.

    Do you often feel lonely? What do you do when you feel that way? Hide yourself away and spend your time reading, watching TV or walking around?

You might think that feeling lonely is just like feeling happy, sad or scared — that it's just one of your various moods. That is true. However, if you let yourself be lonely for too long without dealing with it, you could be making a serious mistake.

    Doctors have known for some time that feeling lonely is bad for the mind. It can lead to mental health problems such as depression, stress and reduce confidence. “Being lonely means not feeling connected or cared for, but it's not about being mentally alone,” Lisa Jaremka, scientist from Ohio State University, US, told Live Science in January. And there's growing evidence that not having friends is connected with physical illness as well.

    In 2006, for example, scientists studied 2,800 women who had cancer. They found that those who had few friends or family were five times more likely to die of their disease than women with many social contacts. Also, even healthy people had a better chance of falling ill if they felt left out by others, according to the BBC.

    The results have scientists thinking that loneliness might hurt the immune system(免疫系统), which protects the body from diseases.

    Hoping to prove this theory, Jaremka and her research team put volunteers(志愿者) through a stress test. During the test, volunteers were asked to make an unprepared speech in front of a group of stony-faced people. The researchers found that volunteers who said they were lonely in their daily lives felt more stress during the test. And their blood samples showed that all the stress had managed to cause harmful changes to their immune system.

     “Loneliness has been thought of in many ways as a chronic stressor(慢性增压器) — a socially painful situation that can last for quite a long time, ” explained Jaremka, who led the study.

    The number of people suffering from loneliness is increasing all over the world. However, solving the problem is easier said than done. It won't work to just “tell anyone to go out and find someone to love you”, said Jaremka. “We need to create support networks.”

    “Now I just don't believe that.” Surely all of us, at some point, have watched a movie and thought: It's simply badly researched, or, the makers must think we're fools.

    If movies were completely scientifically accurate, they'd probably be as interesting as a Physics 101 lecture. In real life, there are no explosions in space, gas usually doesn't explode from a lit cigarette, and Bruce Willis/Jackie Chan/Will Smith would most likely be in a coma(昏迷) after getting kicked in the head.

    Recently, the British newspaper The Daily Telegraph ran a humorous piece on unconvincing tech moments from some top movies. Let's see what they are all about.

    Telegraph writer Tom Chivers' first example from the end-of-the-world movie Independence Day, in which a character comes up with a virus capable of destroying Windows, the computer system the alien(外星人) spacecraft uses. “It's a good thing they didn't have Norton antivirus,” jokes Chivers.

    It's just one case of a movie that takes a lot of license with its science. Another one Chivers mentions is from Star Wars, where glowing beams of light raveling through space look very impressive. The problem is that in space there are no air particles(颗粒) for the light to reflect off. In reality, they'd not be seen, which wouldn't look so cool on the big screen.

    Chivers' second piece of Star Wars nonsense is the sound the fighters make in the movies: “the bellow(咆哮) of an elephant mixed with a car driving on a wet road”. But sound needs a medium to travel through, like air. In space, there wouldn't actually be any sound at all.

    Few people would deny that the mind-bending Matrix films make for great viewing, but for Chivers, the science in the movies is a little silly.

    And finally, as Chivers points out, DNA is not replaceable. But this bit of elementary genetics passed the makers of the 2002 Bond film Die another Day by. In the film the villain(坏人) has “gene therapy” to change his appearance and his DNA, which is completely impossible.

    Larry was on another of his underwater expeditions(探险)but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.

    Larry first began diving when he was his daughter's age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children his age were not even allowed to dive.

    After the first expedition, Larry's later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.

    Larry's first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them. Fortunately for him, a man offered to take him around the different Spots for free. Larry didn't even know what the time was, how many spots he dived into or how many photographs he had taken. The diving spots afforded such a wide array of fish and sea creatures that Larry saw more than thirty varieties of creatures.

    Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater expedition.

    The most famous war movies reflect the American public's continuous fascination with World War II and the Vietnam War. Many movies of this kind have been well-received when they were first shown, but few of them have enjoyed lasting fame and popularity. The films on the list of the five most famous war movies still remain fresh and are popular among many people.

    Since the age of three, Chelsie Hill had dreamed of becoming a dancer. That dream nearly ended one night in 2010. Hill was in a car accident that put her in hospital for 51 days and left her

    paralyzed (瘫痪). For most people, that would have destroyed any hope of a dancing career. For Hill, it was the beginning. Far from being a difficult, her wheelchair encouraged her to think a lot of her life and she wanted to prove that she was sill "normal".

    "Normal" for her meant dancing. With half of her body taken away, Hill had to move it with hands. It took a lot of learning and patience, but she still made it in her wheelchair with her non-disabled high school dance team.

    After graduation from high school in California, Hill wanted to expand (扩展) her dance network to include women like her. She met online the women who had suffered various back injuries but shared the same determination with her.

    Hoping to reach more people in a larger city and break down the false belief of wheelchair users, Hill moved to Los Angeles in 2014, formed a team of dancers with disabilities and named it the Rollettes. As she always believes, dancing on wheels can be just as good as foot-based dance.

    In disabled dance competitions, all dancers from her team gave great performances and they were having fun. And the audience's cheers, whistles and applause (掌声) suggested that the fun was spreading.

    Hill has achieved what many of us never will: her childhood dream. But the Rollettes has helped her find something else just as satisfying. Every year she holds a dance camp, the Rollettes Experience for wheelchair users of all ages to help them find their inner heroines (女英雄). In 2019. over 173 women from ten countries attended the Rolettes Experience. For most of these women, it was the first time they had felt they belonged .Edna Serrano told a reporter that being part of the Rollettes team challenged her to be more independent. “It even gives me the courage to take up driving." she said.
