5
High
school
students
do
in
their
free
time
Last
month
we
asked
our
students
about
their
free
time
activities.
Our
questions
were
about
exercise,
use
of
the
Internet
and
watching
TV.
Here
are
the
results.
We
found
that
only
15
percent
of
our
students
exercise
every
day.
45
percent
exercise
four
to
six
times
a
week.
20
percent
exercise
only
one
to
three
times
a
week
.And
20
percent
do
not
exercise
at
all
!
We
all
know
that
many
students
often
go
online,
but
we
were
surprised
that
90%
of
them
use
the
Internet
every
day.
The
other
10%
use
it
at
least
three
or
four
times
a
week.
Most
students
use
it
for
fun
and
not
for
homework.
2b
The
answers
to
our
questions
about
watching
television
were
also
interesting.
Only
2%
of
the
students
watch
TV
one
to
three
times
a
week.13%
watch
TV
four
to
six
times.
And
85%
watch
TV
every
day
!
Although
many
students
like
to
watch
sports,
games
shows
are
the
most
popular.
It
is
good
to
relax
by
using
the
Internet
or
watching
game
shows,
but
we
think
the
best
way
to
relax
is
through
exercise.
It
is
healthy
for
the
mind
and
the
body.
Exercise
such
as
playing
sports
is
fun,
and
you
can
spend
time
with
your
friends
and
family
as
you
play
together.
And
remember
,
“old
habits
die
hard”
.
So
start
exercising
before
it’s
late!
它对于大脑和身体是健康的。
