According
to
a
review
of
evidence
in
a
medical
journal,
runnerslive
three
years61(long)
thannon-runners.
You
don't
have
to
run
fast
or
for
long62(see)the
benefit.
Youmaydrink,
smoke,be
overweight
and
still
reduce
your
risk
of
63
(die)
early
by
running.While
running
regularlycan't
make
you
live
forever,
the
review
says it 64 (be)more effective at lengthening life 65 walking, cycling or swimming.
Two of the authorsof the review also made a study published in 201466showed a
mere
five
to
10
minutes
a
day
of
running
reduced
the
risk
of
heart
disease
and
early deaths from all 67(cause).
The
best
exercise
is
one
that
you
enjoy
and
will
do.But
otherwise鈥t's
probablyrunning.To avoid knee pain,you can run on soft surfaces,do exercises to 68
(strength)your leg muscles(
鑲岃倝
),avoid hills and get good running shoes. Running is
cheap, easy and it's always 69(energy).If you are time poor,you need run for only
half the time to getthe same benefits as other sports,so perhaps we should all give
70a try.

Diets
have
changed
in
China
鈥?/p>
and
so
too
has
its
top
crop.
Since
2011,the country 61
锛?/p>
grow
锛?/p>
more corn than rice. Corn production has jumped
nearly 125 percent over62past 25 years, while rice has increased only 7 percent.
A taste for meat is63(actual) behind the change:An important part of its corn is
used
to
feed
chickens,
pigs,
and
cattle.
Another
reason
for
corn鈥檚
rise:
The
government encourages farmers to grow corn instead of rice
64(improve) water quality. Corn uses less water65rice and creates less fertilizer(

) runoff. This switch has decreased66
(pollute) in the country鈥檚 major lakes and
reservoirs and made drinking water safer for people.zxxk
