2 . For people suffering from depression, there’s an all-natural treatment they should use — getting more exercise. It could help fight depression, even if people have a genetic risk, new research shows.
For the study, researchers collected information from nearly 8,000 people and found those with related genes were more likely to have depression over the next two years after examining them. But that was less likely for people who were more active at the study’s start, even if they had a family history of depression. Higher levels of physical activity helped protect even those with the highest genetic risk of depression.
Both high-intensity (高强度) exercise and low-intensity activities were associated with a reduced risk of depression. Adding four hours of exercise a week could lower the risk of a new episode (一段经历) of depression by 17%, according to the study. “Our findings strongly suggest that, when it comes to depression, being physically active has the potential to remove the added risk of future episodes in individuals who are genetically risky,” said lead author Karmel Choi. “On average, about 35 additional minutes of physical activity each day may help people to reduce their risk and protect against future depression episodes.”
Depression is a common mental illness globally, with more than 264 million people affected. “Depression is so ubiquitous, and that underlines the need for effective approaches that can impact as many people as possible,” Choi said. And mental health and primary care providers can use the findings to advise patients that there’s something meaningful they can do to lower their risk of depression.

3 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.
But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.
According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.
To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.
“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.
Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.
It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

Sports Day was getting close in the school. All the children were very excited and were practicing for the big race. John, one of the fast runners of the school, was confident that he would win for he was not doing anything at all. “You have to work hard to come first in the race John. You are not practicing at all,” said John’s mother.
“Mom, you know how fast I am! Why should I waste my time running? Only I will win; no one else will win!”said John. “John, you may be right but talent (天赋) without hard work is not good at all. This laziness of yours will cost you greatly,” his mother warned him. John just laughed. He was so confident that he would win the trophy (奖杯) as no one else in his class was as fast as he was!.
Tim, a classmate of John, was also participating (参加) in the running race. He was not a fast runner. However, he practiced till late at night and had developed great endurance (持久力) to run the race.
There were a few days left for the Sports Day but John did not practice at all. On the other hand, Tim practiced day and night.
The Sports Day was almost around the corner but John was confident that no one could beat him and had not practiced at all. But Tim with his hard work had become a very great runner.
At last, the Sports Day arrived. All the students showed up on the ground to cheer their favorites. The coach blew the whistle (口哨) and everyone began to run toward the finishing line. It was so exciting. John and Tim left all the racers far behind. Both of them were neck to neck.

7 . My family first moved to Colorado 22 years ago. Los Angeles was too expensive and it was difficult to find well-paying jobs and affordable housing. Colorado became our next dream place. Settling into a small town in the Front Range, my parents found hard jobs.
Growing up in this small town, I remember my parents working hard to get past the language barrier. My mom, especially, tried her best to ensure she knew all that she needed to know about like my parent-teacher meetings and extracurricular (课外的) activities. One of those extracurricular activities that I signed up for was football. At that age, football was cool and all, but I was more into playing Pokémon and other video games. Football didn’t draw me in.
Big football tournaments (联赛) would come around like the World Cup, the Copa América and the Gold Cup, and the Mexican National Team would play in these tournaments. I would sit there in our living room and unmindfully watch the games while my parents would go crazy with enthusiasm ( 热情). I would sit there and play my game. My dad would look over and tell me that I should be paying attention carefully to the game and that I should care more about whether Mexico would win the match than my video games.
Both of my parents’ workspaces were crowded (占满的) with other workers. My mom worked with people from all over Latin America. Everyone’s topic of choice at work would always turn to how their national football team was doing. It was a way to show pride in the countries where they had grown up.
I grew up loving football more and more. The more I learned about my Mexican roots (根), the more I tried to find ways to express pride in them in the United States.1. Why did the author’s family move to Colorado?

I yawned (打哈欠)as I got off the last step of the bus. I had woken early that morning, and had not been able to sleep on the long ride from Riverside High, thinking about that day’s race, the Eye Opener. I had never raced in a state-wide race before. Over thirty high school teams ran, along with quite a few colleges. The rest of my team and I unloaded the bus, and we relaxed and waited for our race patiently.
“Start warming up,” our coach told us, roughly forty-five minutes after we arrived. After finishing our stretches, we headed over to the starting line, eager for the race to begin.
The starter walked to the middle of the field. “There will be two commands,” his voice boomed, ‘‘Runners set, then the gun. If you hear another shot, return to the starting line to start again. ” My heart raced as I got my legs ready to race.
“Runners set!” the starter shouted Bam! The gun fired, and he rushed out of our way. Adrenaline (肾上腺素)rushed through my body as I raced through the mass of runners. As I rounded the first turn, my schoolmates greeted me with heartening shouts. Then, in what felt like only one minute, I arrived at the one mile mark.
“6’10”, a man declared as I ran by. I tried to ignore him, but my legs began to burn as I realized I had run a mile and still had two to go. I slowed down my pace, for I knew the second mile was the worst of all three. Minutes later, I felt horrible. My legs ached, feeling like lead blocks. My vision was clouded as sweat dropped down into my eyes, and my arms felt as if they would fall off if I swung them one more time. Just as I almost reached my limit, a boy passed me. He also seemed to have lost strength but soon he was a little ahead of me.

________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Thin, average, and undisciplined, I was the underdog of the boys’ basketball tryouts (选拔赛) in seventh grade. Making the team was very important to me. Although I was extremely nervous, I truly thought I would make the team. But I went in overly optimistic, and quickly faced a cruel reality check.
When on the court, I huffed and puffed like an old man on his last legs; clearly, I was out of shape and having trouble keeping up. When it hit me that this was only the first day, and that there was a second to follow, I realized I would have to step it up in order to gain a spot on the team.
Unfortunately, day two went exactly like day one: I missed shots, passed badly like an out-of-breath fool. Hoping the coach was not watching all my bad moves, I had trouble keeping a positive attitude. Finally, Coach-who at five-foot-four usually seemed small, posted the lists of the Boys A and B Teams. Everybody quickly ran to catch a glimpse of the chosen few.
After scanning the list once, twice, three times, my name was nowhere. Although I had predicted the disaster that had now settled on me, with my head hanging. I slowly walked to the car. This experience definitely had not gone as I planned.
On the way home, I complained “How could that foolish boy is a better choice than me? And…”
“Adam!” my mom cut me off. “Why don’t you realize maybe you need a little more practice? You’d better go to basketball camps next summer.”
Although I did not want to believe her, I knew it was true. Failing to make the team was nobody’s fault but mine. Right then and there, in the middle of my anger, I realized I had to get my act together.

10 . Clocking 16 hours, 46 minutes, nine seconds, the athlete Chris Niki didn’t finish with the shortest time when he recently completed his first Iron Man Race-but he did quite well.
After swimming 2. 4 miles, the 21-year-old Floridian cycled 112 miles. Even after suffering a fall from his bike during the second leg of the race, he called on his inner strength to get back up, keep going and get the job done. And then he ran a 26. 2-mile marathon (马拉松) to become the first competitor with Down’s Syndrome (唐氏综合征) in the world to successfully cross the finish line in the history of the Iron Man Race. For his efforts, Niki also earned himself a place in the Guinness Book of World Records.
“To Niki, this race was more than just a finish line and a celebration for the success,”his dad said. “The race has served as a chance to become one step closer to his goal of living a normal life. It’s about being an example to other kids and families that face similar difficulties. Those with Down’s Syndrome will be prompted to live a life like normal persons.”
Niki trained between four and six hours a day to prepare for the event, and that training paid off.
“Goal set and achieved, ” Niki posted on Instagram, where he has 33, 000 new followers. “Time to set a new and bigger goal for 2021. ”
One of Niki’s biggest fans, all-time tennis great Billie Jean King, tweeted the perfect response: “No limits. No boundaries (边界). Keep dreaming big and going for it！”
As for that medal he won for completing the race, he gifted it to his loving mom. With hopes of competing in the 2022 Special Olympics scheduled in Orlando, it looks as if Chris Niki has plenty of big dreams yet to come true.
