1 . 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.

After watching my son Todd run in a race, I made my usual comment, “Todd, I can walk faster than those women run.” Todd laughed as he knew I wasn’t a runner. “Mom, how about you running with me next year in this race?” Without thinking, I quickly accepted this challenge. I felt this was going to be a piece of cake!
When it was almost time for the race to occur the next year, Todd had been in hospital for a long time because of a car accident. Todd and my friends started to encourage me to run the race. I decided I should keep my promise to Todd and run the race. The first thing I did was go out and buy some running clothes. I might as well look good even though I hadn’t trained at all.
The day of the race came. I wished Todd could be there with me, but I had to start off alone. It wasn’t long before some racers started to run next to me and talk to me. I wouldn’t like to talk because I wanted to focus on my running. However, one guy was very talkative. He kept saying how tired he was, and that I must be tired too. He talked on and on. The race was over and this guy’s wife won! I didn’t mind this result. I was just happy to finish the race and keep my promise to Todd.
Todd asked about the race when I went to the hospital. I told him what had happened and how this guy would not stop his negative talk. Todd laughed and set me straight, “Don’t you know what this guy was doing? He thought you were the competitor by the way you were dressed. He wanted his wife to win.” Only then did I figure out the truth, so I decided to continue taking part in the race the next year; I wanted to win this time.
The following year I did train. I even bought some tapes called “Win at Sports” and listened to them daily. These tapes gave ideas about staying behind and knowing when to make your move.
Paragraph 1:
When it was time for the race, I was all dressed and ready.

Paragraph 2:
I stayed behind this guy’s wife in almost the whole race.

In high school, Dad got me to play football in the first place. I enjoyed throwing the ball around with my friends, but I didn’t think I had what it took to play on a team. “I’m no football player,” I told my dad. “You’ll never know what you’re capable of unless you give it a try, Adam,” he told me. So, I did. It would give me a much-needed sense of belonging and some confidence. I remember how proud he was when I won some awards and the hug he gave me after I received my congratulation letter. There was rarely a game where Dad wasn’t on the sidelines, cheering me on.
Four years of hard preseason football camps came down to my last game. I urged my dad to bring our video camera.
I waved at my parents before the opening kick-off, and put on my game face. My pads broke as I made contact with the offensive players. I grabbed at the clothes of their running back and dragged him to the field. A loud cheer came from the sidelines. There was Dad with the camera, cheering like crazy. By the end of the game, I had stopped seven players and a sacking (擒杀) — my best performance ever, a perfect end to my career. I ran into my dad’s arms. I was sweaty and smelly, but he hugged me anyway. I couldn’t wait to watch the tape — experience every moment again.
As soon as we got in the house, I took the tape out of the camera and put it in the player. My dad, mum, sister and I sat down in the living room in front of the big screen TV. I pressed Play. The video started. The two teams, lined up before the game, then the running back taking the handoff, running up to the line, me reaching out, and then…the sky and clouds! I could hear my dad screaming “Way to go, Adam!” as images of the sky shook up and down on screen.
Paragraph 1:
I leaned forward to see the next big play.

Paragraph 2:
The tape ended and Dad was quiet.

Dave had loved basketball for as long as he could remember and he had never had a day without playing it. At primary school and junior high school he joined basketball clubs, attended training programs and watched basketball games, from which he learned the moves of the star players, wishing to play in a professional team like them and shine on the court.
Now as a senior high school student, however, his dream of becoming a professional player was dimming (变暗) because he was only of average height. He had to give up the hope of joining the school team. The guys on the school team were all tall boys who played matches and won honors for the school. They were like heroes. Dave watched them play and cheered them but he knew he would never be one of them.
Dave felt it a pity not to be tall enough, but this didn’t stop him from pouring his passion into basketball. He just played for the love of the sport. He played in the school gym with other boys or by himself every day, even during holidays and weekends, when it was open for two hours in the morning. He enjoyed every minute on the court making every effort to play better.
It was one Saturday morning. Dave was playing in the gym by himself, as all the other boys were busy with other weekend affairs. Then he noticed a tall boy approaching. It was Lankas. Everybody knows him as captain of the school basketball team. “Hi, Lankas,” Dave greeted him. “My name is Dave.” “Hi, Dave,” Lankas replied as he got closer. “Nice to see you here. Do you need an opponent to play against?” Dave was shocked, frozen right there, unable to believe his ears but somehow, he answered, “Why not?”

Ronaldo Luiz Nazario de Lima was born on 22 September 1976 in a poor suburb of Rio de Janeiro. Like most of his childhood friends, Ronaldo began his football (soccer) career playing barefoot in the streets of his neighbourhood. At the age of 14, he joined Sao Cristovao football club and only two years later became the star of Cruzeiro Esporte Clube in Belo Horizonte

Mary waited anxiously for her turn in the empty dressing room. Never had she been so nervous before. This competition was of vital importance to her comeback. “If I can win today,” she said to herself, “I can dance on the national stage next month.” Three months ago, her left arm was seriously injured in a car accident. After the medical treatment, she began to recover slowly. She practiced over and over again in order to regain her dancing skills.
“Hi, Mary,” in rushed her friend Jessica “How is your arm? Is it going to influence your performance?”
“I guess it can be tolerated for I am to win the match.” said Mary with a determined look.
“Admirable! But I hear that a girl called Linda is really gifted and strong. She can be your real well-matched competitor. Come on!”
After Jessica left, Mary decided to practice her most difficult spin. “If I don’t try harder, I won’t grasp this chance.” She thought. But her arm began to hurt, making her worried. “Mary, what makes you think you have a chance tonight?” she said to herself. After the pain was gone, she continued to warm up.
A slim girl hurried in and put down an equipment bag on the chair. Then, she took out her dance dress quickly and put it on skillfully. Seeing Mary, she smiled politely and said “Hi, I’m Linda. I am the next one!” Mary nodded in reply but felt uncomfortable. “This is just my competitor. Because of her, I may lose tonight.” Her mind was wandering when Linda let out a scream, “Oh, God, I can’t find my music tape!” Linda searched her bag but in vain. “It may be missing on the way.” With these words, she then rushed out.

Suddenly, Mary caught sight of a black box under the chair where Linda put her bag.

All parents know exercise is important for children: It can lower heart risks, control weight,and help kids do better in school. Plus, outdoor activities at an early age can go a long way toward helping children form healthy habits for life. In other words, exercise is needed for healthy development. But don’t expect kids to understand about those things. Some kids just aren’t into exercise, but that shouldn’t mean they have to be addicted to the TV. So parents could do something to help inactive son or daughter fall in love with physical activity.
If parents sit in front of the TV every night, a bag of chips in hand, kids aren’t likely to respect restrictions (限制) you set on their screen time either. So check your own viewing behavior, and serve as a role model by putting physical activity into your everyday life. When you can, walk instead of driving. Regularly participate in activities that you enjoy and let your kids see — and hear about — how much you enjoy them. In this way, they may “do as the Romans do”. Make sure that children’s fitness is included in the family schedule in the same way that school, work, shopping, and family gatherings find their way onto the calendar. You and your children are more likely to stick to an exercise plan if you incorporate it into your life on a routine basis. And your children will begin to expect and accept that Sunday morning usually means a hike ride, and a couple of nights after dinner the family takes a light walk through the neighborhood.
Children who aren’t naturally good at physical activities may be self-conscious about their lack of physical skills and even fear public failure. These kids need all the support and encouragement from parents. Negative comments don’t work and will only serve to make your child feel bad. Remember, acknowledge the effort — choosing to be active or trying to improve a skill — rather than the outcome.
