The

thinks
exercise
is
the
best
way
to
relax.
Because
it
is
healthy
for
the
mind
and
the

and
you
can
spend
time
with
your
friends
and
family
as
you
play
together.
No,
I
don't

Last

about

activities.
Our
questions
were
about
exercise,
use
of

and
watching
TV.
Here
are
the
results.
We
found
that
only
fifteen
percent
of
our

exercise
every

Forty-five
percent
exercise
four

six
times

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

six
times

And
eighty-five

Although

······的答案
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!
