advantages
and
disadvantages
of
cell
phones(手机的利弊)
1．手机使用的普遍性；
2．手机的优点；
3．手机的危害及我的建议。
[写作导航]先指出当前手机使用很普遍，然后用事实(随处可见人们用手机通话，许多大学生、高中生都有手机)来支持主题句；手机的优点主要是方便通信，甚至上网，还体现在突发事件(疾病、交通事故)的求助上；手机的缺点主要是辐射和干扰他人，因此我建议尽量少用，重要场合(开会、上课时)关机。

cell
phones
have
become
increasingly
popular
in
china
these
days.
wherever
you
go
you
can
see
people
using
cell
phones.
many
college
students,
even
high
school
students,
have
cell
phones.
cell
phones
have
brought
people
a
lot
of
benefits,
but
the
most
important
is
that
they
are
convenient.
with
cell
phones
in
their
hands,
they
can
keep
in
touch
with
anybody
they
want.
if
they
want
to
get
some
information
from
the
internet,
they
can
easily
have
their
dream
realized
via
cell
phones
too.
furthermore,
if
someone
has
a
heart
attack
or
a
traffic
accident,
a
call
to
emergency
hospital
or
to
the
police
can
quickly
bring
him
the
help
he
wants.
however,
cell
phones
can
also
bring
people
problems.
the
most
serious
is
the
electric
wave
radiation
which
is
thought
to
be
harmful
to
users'
brains.
another
problem
is
that
when
people
are
having
a
meeting
or
having
a
class
or
at
a
concert
etc,
the
ring
of
the
cell
phone
may
interrupt
others.
so
i
think
people
should
use
cellphones
as
little
as
possible
and
turn
them
off
when
they
are
attending
important
meetings
or
attending
classes.
