A recent research shows that physical activity(体育活动) may help students do better in their classes. The research comes because educators in some countries are reducing time for activities like P.E. class.
Researchers go over the results of fourteen studies. Twelve were from the United States, one from Canada and one from South Africa. The studies appeared between 2009 and 2013. They included more than 55,000 children, aged six to eighteen.
Thomas Singh, one of the researchers, says the studies showed a relationship between physical activity and scores on subjects such as math, English and reading. Ms. Singh offers some possible explanations (解释):
“ There are, first, physiological (生理的) explanations, like more blood flow, and so more oxygen (氧气) to the brain. Being physically active means there are more hormones（ 荷尔蒙） produced like endorphins ( 脑内啡). And endorphins make your stress level lower and your mood improved, which means you will perform better in class. Also, students who take part in organized sports learn rules and how to follow them. This could improve their classroom behavior and help them know what they should do.
All in all, the finding tells us that physically active kids are more likely to do better in school. Ms. Singh says schools should consider the finding before they cut physical education programs.

What’s the most important thing for you to have in your life? Somebody mentions hard-work, others suggest knowledge, love and luck.

　　If you arrange the 26 English letters alphabetically(按字母表的顺序)and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c…, you can change an English word into a number. So hard-work becomes 8+1+18+4+23+15+18+11=98, meaning 98 is its mark; knowledge: 11+14+15+23+12+5+4+7+5=96, while love: 12+15+22+5=54, and luck: 12+21+3+11=47, a small mark. None of these words can give one a full mark. What about money? It can’t , either.

　　Then what else? Don’t be worried. You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude. Yes, attitude is the word. See for yourself: attitude:1+20+20+9+20+21+4+5=100，a full mark.

　　Most times people hope for a better life. It is possible if you will have a change for the better after you have changed your attitude. When you change your manner and become friendly to others, you’ll meet more smiling faces towards you.
