1 . Some educators told us that more years of school could help students get higher scores on intelligence tests.That was a finding of a study of teenage males in some countries.Now，another research shows that physical activity may help students do better in their classes.

The research comes as educators in some countries are reducing time for activities like physical education.They are using the time instead for academic(学术的) subjects like math and reading.The studies appeared between 2008 and 2014.They included more than 55,000 children，aged 6 to 18.

Amika Singh：“According to the results of our study，we can conclude that being physically active is beneficial for academic performance.There are，first，Physiological explanations，like more blood flow，and so more oxygen to the brain.Being physically active means there are more hormones(荷尔蒙) produced like endorphins(内啡肽)．And endorphins make your stress level lower and your mood improved，which means you also perform better.”

Also，students taking part in organized sports learn rules and how to follow them.This could improve their classroom behavior and help them keep their mind on their work.

The study leaves some questions unanswered，however.Ms Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement.This is because of differences among the studies.

The researchers said they found only two high­quality studies.They needed more high­quality studies to confirm(证实) their findings.They also pointed out that “results for other parts of the world may be quite different”．

Still，the general finding was that physically active kids are more likely to do better in school.Ms Singh says schools should consider that finding before they cut physical education programs.Her paper on “Physical Activity and Performance at School” is published in the Archives of Pediatric and Adolescent Medicine.

2 . The jobs of the future have not yet been invented.     1     By helping them develop classic skills that will serve them well no matter what the future holds.

1. Curiosity

Your children need to be deeply curious.     2     Ask kids, “What ingredients (配料) can we add to make these pancakes even better next time?” and then try them out. Did those ingredients make the pancakes better? What could we try next time?

2. Creativity

True creativity is the ability to take something existing and create something new from it.     3     There are a dozen different things you can do with them. Experimenting with materials to create something new can go a long way in helping them develop their creativity.

Being able to read people helps kids from misreading a situation and jumping to false conclusions.     4     “Why do you think she’s crying?” “Can you tell how that man is feeling by looking at his face? If someone were to do that to you, how would you feel?”

    5     There are many ways to express thoughts and ideas — music, acting, drawing, building, photography. You may find that your child is attracted by one more than another.

A．Encourage kids to cook with you.

B．And we can’t forget science education.

C．We can give kids chances to think about materials in new ways.

D．So how can we help our kids prepare for jobs that don’t yet exist?

E．Gardening is another great activity for helping kids develop this skill.

F．We can do this in real life or ask questions about characters in stories.
