There have always been a lot of commonly believed but false ideas about being fat and doing exercise. Some people believe that they can't help putting on weight as they get older, while others hold that if they stop exercising, their muscles will turn into fat. Here are some more myths:

I'll never lose weight — I come from a fat family

    Wrong! While we can't change the body type we are born with, we can't blame our genes for making us fat. There's plenty of evidence that fatness runs in families, and the main reason is that they share the same habits of eating too much and exercise too little.

    I am fat because I burn calories slowly

    Wrong! Fatness is not caused by a slow metabolism（新陈代谢）. If fact, although fat people consume more energy that slim people, they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake more accurately.

    Exercise is boring

    Wrong! Anything will become boring if you do it repetitively. The key is to develop a balanced and varied program that's fun as well as progressive. If you enjoy a Sunday walk, take a different route. If you do Yoga, try a tai chi class. If you like swimming, set yourself a distance or time challenge.

    No pain, no gain

    Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something's wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If you don't, rest and seek medical advice.

    Listening to audio books(有声读物) is a really terrific way to enjoy all kinds of books during those times of the day when stopping to sit down and read a book is not an option. An audio book gives the listener hours and hours of entertainment or instruction, or sometimes both at the same time. They are great for people of all ages and make a long road trip a more interesting experience, instead of being boring and dull.

    The biggest benefit of an audio book is that it can be listened to anyplace and anytime. It is a favorite companion for people while they are traveling, commuting, exercising, shopping, working in the garden, or even dusting and vacuuming the house. Using headphones with your favorite audio book player allows you to listen to and absorb the information no matter what might be going on around you.

    Even when you are in a situation that is quiet and are able to enjoy a good audio book, there are still advantages of using your headphones. You can often improve your retention(记忆力) and comprehension of the material when you use headphones because they help reduce distractions from other noises and help you focus better.

    There are a number of different audio books these days that people can choose from. There are audio books on CDs, on audio cassettes(盒式磁带) and also as MP3s and any standard CD player, cassette recorder, or MP3 player that you might use to listen to music can function as an audio book player as well.

    No matter which kind of audio book you prefer to listen to, there is an ever-increasing variety of works that you can select from these days. Virtually any subject matter that is contained in printed books will have at least some audio version available as well. However, books on audio cassettes are starting to become rarer.

    Shyness May Be Partly Inherited(遗传)

    About 92 million Americans are shy, and according to recent research about half of them inherited the trait.

    The studies were discussed at the American Psychological Convention.

    One study, by Harvard University, was of babies 21- 48 months old. It concluded that these babies had a high heart rate when shown unfamiliar people or different toys.

    Although shyness is not new, it has only recently become of interest to researchers. The first study on the genetic connection was in 1979.

    According to Warren Jones of the University of Tulsa, social relations these days are more complex. "With less ritual(仪式) and more complex situations," he said, "shyness is a national concern."

    Not all shy people are anxious and fearful, according to another study. Evidence shows that only half of shy people are tense, worried, and fearful in social situations.

    Many men use shyness as an excuse for failing in social situations, according to C.R. Snyder of the University of Kansas. "This is not true of females. Perhaps, American men are pressured to be assertive(自信的) and successful. So they would rather say they're shy than admit they're incompetent."

    Shy people may do very well socially after the first meeting with someone. In fact, shy people tend to be more stable.

    The psychologists said shyness seems to be cultural. Japan has the highest rating. China and Israel have the lowest rating. The United States rated in the middle.

    One of the most expensive parts of flying is the cost of gas, not to mention the environmental effect it brings. An Israeli startup called Eviation Aircraft hopes to solve the problems. They displayed the world's first all-electric passenger airplane this week at the Paris Air Show.

    The lightweight plane­playfully called Alice­will be able to fly about 600 miles between charges. So it will focus on transportation between cities. It seats nine passengers and two crew members. A typical flight should cost a customer about $200.

    "The fact that we' re building an electric plane from scratch instead of just refitting an existing plane with a battery means that we can design our aircraft to be more effective and efficient than present planes," said Eviation co-founder Omer Bar Yohay. He predicts that per seat, per mile, the cost would be equal to that of a taxi or train.

    The demand for electrically powered aircraft is projected to reach hundreds of planes per year within the next decade. The change from gas to electric in power is expected to save millions of dollars in fuel costs, not to mention the environmental benefits including significant reduction of air pollution and noise levels.

    When it comes to the new possibilities, Yosef Abramowitz, an energy industry expert, said, "In modern life, it is important to fight climate change and now we have a path to do so in flying." Abramowitz, a tireless advocate for solar power, added, "The batteries will hopefully be charged with solar energy too."

    To help further save fuel costs, the designers have also invented a "taxibot" that drags planes from the passenger gate to the runway, so the planes needn't run their engines.

    After appearing at the Paris Air Show, the Alice will travel to the U.S. for further tests. It is expected that the first commercial flights will take off in 2022.

    "I think for the first time in a very, very long time, we can look at flight again and talk about the next revolution," Bar Yohay said.

    Nezha is the subject of the latest feature, which officially opens in cinemas in China on Friday. Nezha has earned hot reviews and is ranked higher than Monkey King: Hero is Back. It is also China's first 3D animated feature film released in IMAX format.

    Since July 13, previews of the film have taken more than 140 million yuan at the box office and the film has a score of 8.8 points (out of 10) on China's largest filming rating site, Douban. It took Jokalate Yang Yu, the film's director and screenwriter, two years to improve the script (剧本) of Nezha, and the film was in production for three years. It is the most complex animated production ever made in China. Nezha has more than 1,300 special effects shots, and it took over 20 Chinese special-effects studios, employing more than 1,600 people, to realize the film's fairy tale setting, the mysterious Dragon King's palace and a fight between fire and water. One splendid scene alone took two months to complete.

    Yang made up his mind to produce an animated film on the theme of breaking the traditional styles and changing fate to the opposite. Yang chose Nezha as his vehicle, the representative of the rebellious (叛逆的) but righteous youth. However, compared with the original novel and past animated versions, the relationships between the characters are given modern meaning. In Yang's film he is fighting prejudice: Nezha is hated and feared. But Nezha believes his fate is not predetermined and that he can choose to be a devil (恶魔) or a god.

    "After watching so many domestic animated films, only Nezha and Monkey King: Hero is Back have made me fascinated," a Weibo user commented under the promotional video.

    "Epic! I finished watching Nezha in tears. The content-rich story, vivid characters, and amazing visual effects, work together to create a 110-minute roller-coaster (过山车) watching experience," a Douban user commented.

    "Bravo! Couldn't believe a domestic animated film can be created with such a well-developed story. The image of Nezha in this film has been overturned but his rebellious spirit is well-established. I'm sure Nezha is gonna go viral this summer!" reads another comment on Douban.

Natural silence—the kind when you hear nothing but the sound of nature around you—is becoming increasingly scarce.The rumblings of man-made noise can be heard even in the remote corners of national parks and deep in the Arctic Ocean.

 This is having a troubling effect.In humans,noise pollution has been linked to cardiovascular diseases,mental health problems and cognitive impairment in children.In wildlife,it's disrupting navigation,mating rituals,communication and can cause hearing loss."We're losing the ability to listen to nature without noise pollution," says sound recordist Matt Mikkelsen.He's part of the non-profit organization Quiet Parks International,which aims to identify and preserve the planet's last quiet places.

 Recently,this took him to Boundary Waters Canoe Area Wilderness in northeastern Minnesota.No cars,motor boats,electricity or telephone lines are allowed in the 1-million-acre area,making it a strong candidate for Quiet Park status.But listening back to the recording,Mikkelsen can hear the low hum of a commercial jet flying far away.

 Quiet Parks hasn't yet decided if Boundary Waters meets its criteria—it's one of 260 potential sites around the world that the organization is currently exploring.The team will analyze the sound recordings from each location and consider them alongside other data.

 In recent years,the world has been getting louder,with cities and towns expanding and an increasing number of beeping cars,whooshing airplanes and cargo ships with blasting horns.But during the pandemic,there has been momentary respite.In 2020,global air travel was down by 60% and road transport decreased by almost half.Scientists in Europe found that noise caused by humans fell by up to 50% after lockdowns were imposed.

"People relished the silence," says Mikkelsen."There were no airplanes in the sky and cars weren't on the street...It was a miraculous thing to be able to hear the world,all of a sudden,free from noise pollution,"he says.Since the start of the pandemic,Quiet Parks says it has experienced a huge surge in interest for quiet places."I hope that we can take that desire for a world with less noise forward," says Mikkelsen,"and appreciate the spots we have,where we can go and not experience noise pollution."
