If you want to improve your child’s results at school, you could do a lot worse than ensuring that they do plenty of exercise. Scientists have already shown that physical activity can make you brainier. But a team in America has used scans to show that an important part of the brain actually grows in children who are fit. These youngsters tend to be more intelligent and have better memories than those who are inactive.

　　Scientists also found that one of the most important parts of their brains was 12 percent larger than those of unfit children. They believe that encouraging children to take exercise from a very young age could help them do better at school later. Researchers from the University of Illinois, in the U.S., studied the brains of 49 children aged nine and ten using a magnetic resonance imaging scan (核磁共振摄影扫描), a technique which provides very detailed pictures of organs and tissues in the body.

　　They also tested the fitness levels of the children by making them run on a treadmill (跑步机). The scientists found that the hippocampus, a part of the brain responsible for memory and learning, was around 12 percent larger in the fitter children.

　　Professor Art Kramer, who led the study published in the journal Brain Research, said the findings had important implications for encouraging individuals to take part in sport from a young age. “We knew that experience and environmental factors and socioeconomic status all impact brain development,” he said. “If you get some terrible genes from your parents, you can’t really fix that, and it’s not easy to do something about your economic status. But here’s something that we can do something about.”

A. it is worse to ensure that they do plenty of exercise

C. it could be better to make sure that they do a lot of exercise

B. Children who have a larger hippocampus will probably have better memories.

C. You can do something about the genes from your parents.

　　Like most people, I’ve long understood that I’ll be judged by my occupation, that my profession is used by people to see how talented I am. Recently, however, I was disappointed to see that it also decides how I’m treated as a person.

　　Last year I left a professional position as a small-town reporter and took a job waiting tables. As someone paid to serve food to people, I had customers say and do things to me I suppose they’d never say or do to the people they know. One night a man talking on his cell phone waved me away, then called me back with his finger a minute later, saying angrily that he was ready to order and asking where I’d been.

　　I had waited tables during summers in college and was treated like a peon（勤杂工） by plenty of people. But at 19 years old, I believed I deserved inferior（低等的）treatment from professional adults. Besides, people responded to me differently after I told them I was in college. Customers would joke that one day I’d be sitting at their table, waiting to be served.

　　Once I graduated I took a job at a community newspaper. From my first day, I heard a respectful tone from everyone who called me. I assumed this was the way the professional world worked--- politely and formally.

　　I soon found out differently. I sat several feet away from a person in advertising department with a similar name. Our calls would often get mixed up and someone asking for Kristen would be transferred to Christie. The mistake was immediately clear. Perhaps it was because of money, but people used a tone with Kristen that they never used with me.

　　It’s no secret that there’s a lot to put up with when waiting tables, and fortunately, much of it can be easily forgotten when you pocket the tips. The service industry exists to meet others’ needs. Still, it seemed that many of my customers didn’t get the difference between server and servant.

　　I’m now applying to graduate school, which means someday I’ll return to a profession where people need to be nice to me in order to get what they want. I think I’ll take them to dinner first, and see how they treat someone whose job is to serve them.
