The 2016 Rio Olympic Games have come to an end. Without doubt, many Chinese sports fans sat in front of the TV and cheered our athletes on, hoping that they would get as many gold medals as possible.

    But sometimes our desire for gold medals can result in the sadness of failure. When Liu Xiang, China's track hero, pulled out of the Beijing Olympics due to injury, he greatly disappointed many Chinese sports fans.

    But things are different now. In the 2016 Rio Olympic Games, we saw a healthier and more lenient Chinese attitude toward the sportspeople, fully in line with the Olympic spirit.

    China didn't win any gold medals on the first day. But, instead of criticizing the athletes who failed to finish on top of the podium(领奖台), the majority of fans were happy with their efforts. “Reacting in the right way when an athlete misses out on gold shows the maturity of a person, and is also a challenge for a country to face up to in the process of development,” commented CRI.

    Swimmer Fu Yuanhui won fans' hearts, even if she only won a bronze medal in the 100m backstroke final. Her fans on her Sina Weibo micro blog have increased 100,000 to over 6 million. Many sports fans appreciated her straightforward character and attitude toward competition.

    “The warm support from Internet users shows that public attitude toward competitive sport and the Olympics have gotten to a higher level,” said an article in the People's Daily.

    A few years ago, Darla Hoff painted a pumpkin face onto a round straw bale(捆)at A1 and Karen Goldman's farm in Idaho Palls to advertise her U-pick pumpkin field. While Darla has stopped growing pumpkins, the annual tradition of straw bale art lives on at the farm and has drawn friends and neighbors to participate in it. Past creations have included an owl, Minions, tractors and a teddy bear.

    To make the tractors, A1 baled round straw bales in two different sizes smaller ones for the tractor's front tires and larger ones for the rear(尾部). Large square bales made up the bodies. Jerry Kienlen used his farming equipment to arrange the bales in the shape of two tractors. Then it was time to bring the tractors to life. Karen and her daughter. Lana Hedrick, secured some green paint, and A1 got some red paint. Darla's husband, James, sprayed the creation with a paint gun. For the finishing touches, Steven donated two shiny exhaust stacks (排气管),and A1 and Karen donated two steering wheels from their farm parts.

    The farm's annual straw bale art projects have now become a way for everyone to celebrate the end of another growing season. It's just something fun to do together after harvest. This neighborhood has always been close. Generations of these families have grown crops in this soil. Raised on the farms where they live now, they grew up together as their elders did before. A1 and Karen are truly super neighbors. Every year they also grow about two acres of corn to give away. Anyone can pick some, or A1 and Karen will even deliver. And during long Idaho winters, everyone gathers at the farm to enjoy fresh coffee and cookies.

    This year's straw hale creation theme is Straw Wars. And all eyes will be on A1 and Karen's farm as their creation takes shape.

    British Writer John Donne once said: "No man is an island; every book is a world." As an enthusiastic reader, I can't agree with the latter part of the sentence more. Every summer, I endeavor to find some peaceful places where I can attack some classics without being disturbed. Thomas Hardy wants to live far from the madding crowd. I am no friend to chaos, either.

    I read George Orwell's 1984 in a New England beachside cottage with no locks on the doors, no telephones or televisions in the rooms. 1984 is a good book that needs deep reflection. Attempting Sound and Fury lying on the bed of a poorly-occupied motel, however, was less fruitful: I made it through one and a quarter volumes, but then my eyelids were so heavy that I couldn't keep them open.

    But this summer I find myself at a loss. I'm not quite interested in J. D. Salinger, say, or Frankenstein. There's always War and Peace which I've covered some distance several times, only to get bogged down in the "War" part, set it aside for a while, and realize that I have to start over from the beginning again, having forgotten everyone's name and social rank. How appealing to simply fall back on a favorite—once more into The Call of the Wild or Alice in the Wonderland, which feels almost like cheating, too exciting and too much fun to belong to serious literature.

    And then there's John Steinbeck's The Grapes of Wrath. This title do not amaze but confuse. We're never short of sour grapes, but we've never heard of angry grapes. Anyway grapes are my favorite fruit of summer. These stone fruits can always make me feel cheerful and peaceful all at once.

    A study found wireless signals are able to pass through bags and suitcases to judge the sizes of dangerous metal objects and identify them." These items could include weapons, chemicals, laptops and batteries for bombs, "the research team said on Tuesday.

    Research suggested that Wi-Fi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material. The study led by researchers at the Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed a wireless device with two to three antennas(天线)that could be fitted in existing Wi-Fi networks.

    The detection system analyzes what happens when wireless signals go through and bounce off objects or materials. The approach, which the paper states, works by separating the wireless interference(干扰)caused by two factors of objects-the material and shape." Most dangerous objects such as weapons are usually metal or liquid, which have significant interference," researchers said.

    When it was tested on a backpack, the accuracy rate topped 95 percent. "But the accuracy dropped to about 90 percent when objects inside bags are wrapped. And the tech could save lives if used in museums, stadiums, theme parks or schools," the team said, noting its design can inspect bags or luggage without being an exposure to privacy.

    It uses channel state information (CSI) that is readily available in low-cost Wi-Fi devices." This could have a great impact on protecting the public from dangerous objects," said Yingying Chen, a co-author of the study," There's a growing need for that now. In large public areas, it's hard to set up expensive screening equipment like what's in airports. Manpower is always needed to check bags and we want to develop a method to try to reduce manpower.”

    The peer-reviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Network Security, is now published online." Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes," researchers said.

    Huawei Technologies Co. displayed its much-anticipated in-house operating system Harmony OS on Friday, marking what some call the Chinese tech giant's biggest push yet to build its own software ecosystem for the era of the internet of things.

    The move is also expected to weaken the influence of the United States government's restrictions on Huawei using Google's Android operating system in smartphones, analysts said.

    Yu Chengdong, CEO of Huawei's consumer business group, speaking in Dongguan, Guangdong province, said it is difficult to deliver a smooth experience across different devices with the huge amount of codes involved in the Android and Linux operating systems. Linux is an open-source operating system widely used in personal computers and other hardware.

    "Harmony is a next-generation operating system designed to address the challenge," Yu said, adding that it will be able to support a wide range of application situations, including smart TVs, automobiles and wearables.

    The internet of things refers to a network of devices and other objects that can connect with each other and exchange data.

    Yu said the US government's restrictions have accelerated the company's marketing of the system, which now has about 4,000 employees working on it.

    The senior executive said Harmony can be used in its smartphones. But Android is still Huawei's preferred choice for handsets if the company is allowed to use it.

    "But when Android is not available, Harmony can be applied immediately to smartphones. Harmony is ready," Yu added.

    Jia Mo, an analyst at market research company Canalys, said even if Huawei does not use Harmony in its smartphones in the short term, its smartwatches and smart TVs can be equipped with Harmony to widen its use and accumulate more experience in building an ecosystem.

    "Also, more importantly, Huawei chose to build Harmony into an open-source operating system and allow it to be compatible with Android. Thus Harmony will be more accepted by current Android users. This will prevent Huawei from repeating the fate of Microsoft in promoting smartphone systems," Jia said. Microsoft failed to popularize the use of its Windows system in smartphones years ago.

While conquering the world's swimming pools in the late 1990s and the 2000s, Amanda Beard had already included breathing exercises in her training. Several years after the end of her athletic career, she discovered walking meditation. Today the seven-time US Olympic medalist practices walking meditation in nature, around the house, or while walking the dog. It's a daily practice with the focused mindfulness of meditation that contributes positively to every aspect of her life, she says. 

You don't need equipment or a designated space to start. The idea of a walking meditation is to pay attention to the way your body feels, noticing things like the sky, trees, tuning into all of your senses. This means you can meditate "on the go" in the countryside, in the city, in your backyard, and virtually anywhere. A simple, 10-minute walking meditation for beginners requires that you just start at ease. Consider what you hear, smell and see. Think about how your feet touch the ground. Fully focus on these feelings. 

A report in Health Promotion Perspectives also found that walking meditation can improve your balance, adjust your heart rate, boost your mental focus, and help you battle anxiety and depression. "The benefits of meditation are many," says Dr. Schramm, a board-certified family physician and meditation teacher. "When we do this over and over again, we train the brain to focus on only one thing at a time and this increases both our blood flow and actual neuronal (神经元) changes within our brains. "

"The magic of meditation is to be able to help you connect with yourself; meditation shouldn't feel a certain way," says Tara Stiles, a yoga and wellness expert. It's a common mistake in meditation: People fear a wandering mind. "A wandering mind is completely normal," Stiles says. "Even experienced meditators aren't sitting there never having a thought, but when they have the thought they choose to guide themselves back to their breath instead of getting frustrated.
