Do
No.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
fifteen
percent
of
our
students
exercise
every
day.
Forty?-five
percent
exercise
four
to
six
times
a
week.
Twenty
percent
exercise

And

可是我父亲没有开车去那里。(翻译)

water.
My
father,
however,
didn’t
drive

We
all
know
that
many
students
often
go
online,
but
we
were
surprised
that
ninety
percent
of
them
use
the
Internet
every
day.
The
other
ten
percent
use
it
at
least
three
or
four
times
a
week.
Most
students
use
it
for
fun
and
not
for
homework.
The
answers
to
our
questions
about
watching
television
were
also
interesting.
Only
two
percent
of
the
students
watch
TV
one
to
three
times
a
week.
Thirteen
percent
watch
TV
four
to
six
times
a
week.
And
eighty?-five
percent
watch
TV
every
day！
Reading
Although
many
students
like
to
watch
sports，game
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
too
late！
