Runners who encounter visual and auditory distractions (干扰)may be more likely to suffer leg injuries, according to research by the Association of Academic Physiatrists in Las Vegas. Runners often seek distraction from the task at hand. Whether it be music, texting, daydreaming, taking in the sights, or propping a book up on the treadmill(跑步机), more often than not a distraction is welcome. But, researchers from the University of Florida have recently discovered those distractions may lead to injury.

    Daniel Herman, MD, assistant professor at University of Florida, and his team conducted research on the effects of visual and auditory distractions on 14 runners to determine what effect these distractions would have on things such as heart rate, how many times a runner breathes per minute and how much oxygen is consumed by the body.

    The runners were all injury-free at the time of the study and ran 31 miles each week. Dr . Herman's team had each participant run on a treadmill three separate times. The first time was without any distractions. The second time added a visual distraction, during which the runners concentrated on a screen displaying different letters in different colors with the runner having to note when a specific letter-color combination appeared. The third time added an auditory distraction similar to the visual distraction, with the runner having to note when a certain word was spoken by a certain voice.

    When compared to running without distractions, the participants applied force faster to their left and right legs called loading rate, with auditory and visual distractions. They also experienced an increased amount of force from the ground on both legs, called ground reaction force, with auditory distractions. Finally, the runners tended to breathe heavier and have higher heart rates with visual and auditory distractions than without any distractions at all.

    "Running in environments with different distractions may unfavorably affect running performance and increase injury risk," explains Dr. Herman. "Sometimes these things cannot be helped, but you may be able to minimize potentially cumulative(累积的) effects. For example, when running a new route in a chaotic environment such as during a destination of marathon, you may want to skip listening to something which may require more attention - like a new song playlist."

    Dr. Herman's team will continue to investigate the potential relationship between distracted running and leg injuries, and any effect this relationship has on different training techniques that use auditory or visual cues.

    China officially informed the World Trade Organization on Tuesday that it will ban the import of 24 different types of solid waste by the end of this year as part of a campaign to deal with environmental pollution and protect people's health.

    In response to growing public concerns over the potential environmental and health danger caused by the increasing amounts of solid waste imported into the country for recycling and treatment, China passed a special law in 1995 to control imports of waste materials, such as plastics, slag from steelmaking, unsorted scrap paper and discarded textile materials.

    A year later, the country published a list for solid waste imports and began implementing a permit system to control the import volumes and types of waste imported.

    However, due to the lack of effective supervision(监管) and the failure of relevant departments to fulfill their duties, solid waste imports have not been effectively controlled.

    So far, China is the world's largest importer of solid waste. According to the Ministry of Environmental Protection, China imported 7.3 million metric tons of plastic waste worth $3.7 billion in 2016, accounting for 56 percent of global imports of solid waste.

    Correct recycling of solid waste materials is an important part of the global economy, and moderate imports of scrap plastic, scrap paper and scrap rubber products, such as vehicle tires, can to some extent, make up for China's shortage of various raw materials.

    However, the lack of supervision has resulted in the country's severe soil and environmental worsening.

    Given that China's continuing efforts to push for industrial transformation and upgrading have resulted in a noticeable decline in the demand for the materials recycled from solid waste imports. It is right for the country to restrict such imports for the sake of the environment and public health, and to better adapt to the changed industrial structure.

    Last Sunday, my whole family went to the amusement park near our hometown. As we planned the day before, on my brother's 13th birthday. David was two years older than I.

The weather was perfect and everyone was happy. The park was not too crowded. "Fioda," said my brother, "do you want to go on that ride with me?" "Of course," I said. The ride was brand new. I saw commercials(广告) for this huge roller coaster(过山车） on television. I was so excited to ride it. As we got in line, we talked excitedly about what we might experience. We decided that we would both try to keep our hands in the air the whole time. We believed that would make it even more enjoyable. I was so busy talking to my brother that I missed the most important sign—-Empty your pockets before going on the ride. Something bad happened!

    The ride started. It was a really fast roller! Before I knew it, we were upside down. I felt my phone slipping（滑落） from my pocket. My hands were in the air, just as we had promised, and I didn't catch my phone in time. It hit me on the head, fell down to the ground and broke. My parents said I wouldn't have a new phone until I had enough money to pay for it. I need to be more careful. Next time, I'll pay better attention the warning signs as we wait in line for the ride.

    It is increasingly popular for Chinese young people to share their experiences on Social media, such as the “moments” (朋友圈) on popular instant messaging service WeChat.

    “I have been reading 'Jane Eyre' for 40 days with 48,000 words finished,” Li Anqi said. Li has been sharing her reading experience on WeChat moments every day since January. Working in Yinchuan, capital of Northwest China's Ningxia, Li wants to learn English very much, but cannot bare (摆脱) the daily grind (日常工作) of school lessons.

    “I found many of my WeChat friends had been reading books or learning English on mobile reading apps, and I did not want to fall behind,” Li said.

    In January, she spent more than 100 yuan purchasing an online reading class at the Bohe Reading app, which tells customers they can: “Finish reading your first English book here.” At the reading class, teachers assign reading homework and give instructions to 430 class members every day.

    A survey report released (发布) on Thursday said 70.9 percent of primary and middle students in China use the Wechat instant messaging App. At the same time, 75.9 percent of Chinese children have their own mobile phones, according to China National Children's Center.

    The figures were based on a survey of nearly 9,000 children across China. However, 28.8 percent of them never read news online and 43.2 percent have never touched newspapers.

    The Center called for efforts to address the digital divide between urban and rural education and protect children's privacy as Internet users.

    When my family moved to the United States from Colombia, I was 9 years old and knew little about English. As time passed, teachers finally knew all of their students and slowly everyone began to head inside, except for me. No one called out my name, and no one seemed to know I existed. I spent the next month in my new classroom quietly. I felt a wave of fear, loneliness and sadness came over me.

    It turned out the school administration never cared that I didn't speak English, but something else was teaching me English. Every morning when my aunt drove me to school and picked me up, she always had 106.7 Light FM on. It was this station that introduced my young ears to the English sounds of R&B, soul, jazz and much more.

Because of Sabrina the Teenage Witch, I learned the difference between "witch" and "which". While watching the TV show South Park, I was attracted by the funny characters. I related "You bastards!” to anger and saved it in my mental word bank. In fact, thanks to pop culture, the world of English became not so hard to me while it was being turned down at school.

    I also learned how to express my emotions thanks to pop culture. One day at school, we were taking a math quiz and the whole class was quiet. Suddenly, the tip of my pencil broke and I yelled, “You bastards!" Everyone held their breath in surprise and I laughed to myself because something at that moment told me I had just learned my first bad word in English.

    Four months passed before the school placed me into an ESL program. By this time, I was speaking broken English and making myself understood. Finally, I learned how to speak and write English at a more advanced level, and I owe it all to pop culture.

    Maggie had never experienced an earthquake before, only prepared for it. As long as she could remember, preparing for an earthquake was routine (常规的) at school. Her family as well had made plans in the event of a natural disaster. Earthquakes are so much more common on the West Coast of the United States.

    Today Maggie was home alone. Maggie knew her mom would be driving home on the busy freeway, thinking about preparing supper for Maggie's dad. Maggie's dad would arrive at the airport. He was coming home from a two-week business trip.

    Maggie arrived home from school at the regular time. She was taking some biscuits from the kitchen cupboard, when she felt it. First just a tremor (微震), then the violent shaking. Maggie quickly ran under the large, wooden table in the dining room. The sounds of breaking glass and the crashing (坠落声) of many things were frightening. But the table remained undamaged, and Maggie hid herself in fear.

    After what seemed like a century the earthquake appeared to be over. Maggie could hear the sound of water rushing below her in the basement. The smell of natural gas was present in the air. Maggie knew where the main water valve (阀门) was located. Dad had shown her where it was and how to turn it off. Slowly and carefully she came out from under the table. The once tidy home was now almost unrecognizable. As Maggie reached the open basement door she could see the steps were still in good condition. She carefully made her way down into the dark basement. While still on the steps she felt the water rising and rising. Suddenly Maggie felt a lot of pain as a large ceiling beam (天花板梁) hit her head and shoulder. She fell onto some storage boxes…
