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.”

What will you be doing when you are 26 years old? Studying at university or working for a living? Take a look at what Albert Einstein was doing at the age of 26.
100 years ago, Einstein was working in Switzerland. His hobby was physics. Without much money or help, he wrote five papers(论文) for a physics magazine. Three of these greatly changed the study of physics and our understanding of space, time, light and matter(物质). His most famous work is on the Theory of Relativity(相对论). Einstein was given the Nobel Prize for his discoveries. Although he also did many other things later, the years 1905 has been called Einstein’s “Year of Wonders”. It has been 100 years since then. Because of this, the UN has named 05 the World Year of Physics.
Today, over fifty years after Einstein’s death, a question is asked, “ Will there ever be another Einstein?” It may take a long time. After all, Einstein was born more than 200 years after Sir Isaac Newton, another great scientist. Besides, physics is a different field now, and education is different, too. Even if you can’t be the next great scientist, it is still helpful to remember some of the things that made Einstein great. He thought independently(独立地) and read widely. He left with us a formula(公式) for life: If A is a success in life, then A="X+Y+Z." X is work, Y is play, and Z is keeping your mouth shut.
【小题1】The year 1905 is known as Einstein’s “Year of Wonders” because .
| A.Einstein was working in Switzerland in 1905 | B.Einstein was 26 years old in 1905 |
| C.Einstein made some very important discoveries in 1905 | D.Einstein studied physics in 1905 |
| A.Because the study of physics is not enough. |
| B.Because it is hard to make important discoveries as Einstein did. |
| C.Because people don’t work hard any more. |
| D.Because physics is getting more and more difficult. |
| A.Einstein is 100 years old this year |
| B.Einstein has been dead for more than 50 years |
| C.there have been other great discoveries after Einstein’s death |
| D.it is the 100th year since Einstein’s “Year of Wonders” |
| A.Success means years of hard work. |
| B.Success means all study and no play. |
| C.Success means working hard, relaxing and not talking too much. |
| D.Success is a secret that nobody knows. |
