Walking to Exercise the Brain
Do you think sitting and studying all the time will improve your grades?Think again?Getting some exer-
cise may help,too.
New research with old people suggests that taking regular walks helps them pay attention better than if
they didn't exercise.
Previous research had shown that mice learn,remember,and pay attention better after a few weeks of
working out on a running wheel.Mice that exercise have greater bl0od flow to the brain than those who don't.
Their brain cells also make more connections.
Neuroscientists(神经科学家)from the University of Illinois at Urbana-Champaign wanted to find out if
the same thing is true for people.First,they measured the physical fitness of 41 adults,ages 58 to 77,after
each person walked 1 mile.Then,participants looked at arrows on a computer screen and had to use computer
keys to show which way one particular arrow was pointing.
Adults who were physically fit were faster at the arrow task,and their answers were just as accurate as
their less-it peers,the researchers found.The fitter participants also had more blood flow to a part of their
brain responsible for paying attention and making decisions.
In a second study , 15 elderly people who completed a 6-month aerobic-training(有氧运动)course were
faster at attention tasks compared with 14 seniors who just did stretching and toning exercises(韵律操)for
the same amount of time.
So,even going for a walk every 2 or 3 days for just 10 to 45 minutes can help.That should be good news
for the elderly.
The effects of exercising on the brains of younger people haven't been studied yet.Still,it can't hurt to
take occasional breaks and' go for a walk or run around with friends.Whatever you do,though,don't try to
read and walk at the same time.You could end up hurting yourself!
Walking regularly helps elderly people___________.
A.lose weight
B.become happier
C.concentrate better
D.look younger

The Art of Writing Letters Letters-writing is becoming a lost art --- in fact the practice of writing personal letters is diminishing (减少,降低) to such an extent today that they threaten to become extinct (灭绝的,消失的). Since daily events are communicated by newspapers, radio, television and e-mails with great accuracy and dispatch, the circulation of general news --- which formed the chief reason for letters in the stagecoach (驿站马车;定期公共马车) and sailing –vessel days --- has no part in the hurried correspondence of the twenty-first century. Yet people do write letters, and there are still some who possess a gift (才能) for the fresh turn of phrase (措辞,表达方式) that we see in old letters. It may be, though, that in the past the average writing was no better than the average of today, for naturally, the unusually gifted letters are the ones that have been preserved for us over the years. Most people who wonder how they will ever fill a blank sheet of paper find that the difficult part of
A. business letters
B. personal letters
C. invitation letters
D. public letters
