Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元）in our brains.

    Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate (模仿)it，whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further： mirror neurons not only appear to explain physical actions _y they also tell us that there is a biological basis for the way we understand other people.

    Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to ( for example ："The hand took hold of the ball" ) , the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).

    Any problems with mirror neurons may well result in problems with behavior. Much researeh suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.

    Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact(互动）.Indeed, it may turn out to be the equivalent (相等物）for ncurosciencc of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does--well，perhaps you'll understand why.

    In the mid-1950s, I was a somewhat bored early-adolescent male student who believed that ________________________ One day, this approach threw me into embarrassment

    In Mrs. Totten's eighth-grade math class at Central Avenue School in Anderson, Indiana, we were learning to add and subtract decimals (小数).

    Our teacher typically assigned daily homework, which would be recited in class the following day. On most days, our grades were based on our oral answer to homework questions.

    Mrs. Totten usually walked up and down the rows of desks requesting answers from student after student in the order the questions had appeared on our homework sheets. She would start either at the front or the back of the classroom and work toward the other end.

    Since I was seated near the middle of about 35 students, it was easy to figure out which questions I might have to answer. This particular time, I had completed my usual two or three problems according to my calculations.

    What I failed to expect was that several students were absent, which threw off my estimate. As Mrs. Totten made her way from the beginning of the class，I desperately tried to determine which math problem I would get. I tried to work it out before she got to me, but I had brain freeze and couldn't function.

When Mrs. Totten reached my desk，she asked what answer I'd got for problem No. 14. “I…I didn't get anything,” I answered，and my face felt warm.

    “Correct,” she said.

    It turned out that the correct answer was zero.

What did I learn that day? First, always do all your homework. Second, in real life it isn't always what you say but how you say it that matters. Third，I would never make it as a mathematician.

    If I could choose one school day that taught me the most, it would be that one.

    After spending a long day driving the day before, Steinkamp left his hotel around 5:30 a.m. to a funeral in Green Bay, Wisconsin. About half an hour into his journey, he noticed a small strange sound coming from his front tire. By 7 a.m., he still had 70 miles ahead of him, but the noise was so loud that he knew he had no choice but to stop.

    Steinkamp figured there was little possibility that anyone in Wild Rose, Wisconsin-a tiny town with a population of 725-could help so early in the morning. Still, he look his chance at an auto repair shop. Luckily, Steinkamp spotted Glenn Geib stocking the shelves, and he asked for help.Giving Steinkamp a quick look, Geib asked why he was so dressed up, and Steinkamp explained his dilemma.

    The mechanic checked the car and told Steinkamp what he'd feared: the wheel bearing（轴承）was failing. Fixing it would take a few hours, but there was no chance the car would make it that distance without repairs.

    "I must have looked pretty stressed out at this time because Glenn then reached into his pocket, pulled out the keys to HIS vehicle and said 'Take my truck and get going,'" Steinkamp wrote in a Facebook post.

    The men had met just 10 minutes before and didn't know each other's names, but Geib insisted. Steinkamp made it to the funeral. When he came back to the garage seven hours later with a thankful heart, he stuck around to chat with Geib.

    "The 74-year-old mechanic turned a terrible day into a good one with a great lesson." Steimkamp wrote, "Just be kind and help if you can."

    Exercise is known to benefit people's mental health, but scientists recently discovered that too much exercise may have a negative effect on it.

    The researchers studied about 1.2 million people in the United States in 2013, 2015 and 2017. The participants, on average, experienced 3, 4 days of poor mental health each month. Those who did exercise experienced 1, 5 fewer days of poor mental health per month, compared to those who didn't exercise at all. The team found that people who exercised for 30 to 60 minutes three to five times a week had the best mental health, but those who exercised for more than three hours had worse mental health than those who didn't exercise at all.

    The scientists think that people who exercise so much may experience poorer mental health because that much exercise can be a sign of obsessive (强迫症患者) behaviors that have been associated with poor emotional and psychological outcomes. However, the only mental health disorder that the researchers looked at was depression.

    Among those who had been diagnosed with depression, people who did exercise experienced 3.75 fewer negative mental health days than those who did not, showing an ever greater difference, According to the Centers for Disease Control and Prevention. 7, 6 percent of people in the U.S. age 12 and over have depression. While all types of exercise appeared to help with mental health, cycling, gym-based exercise and team sports were the most beneficial.

    The team also looked at more specific factors, like education. People with a college education reported 17.8 percent fewer days of poor mental health than those without that level education Additionally, people in a healthy BMI (体重指数) range reported a 4 percent reduction in poor mental health days thin those whose BMIs were high. Even salary was a factor: compared to people with bower salaries, those with higher salaries experienced a 17 percent reduction in poor mental health days.

    The study showed that exercise can help with mental health, but that in some cases, limiting it may be necessary.
