It
does
all
the
work
around
the
house.
It
is
very
patient
and
never
complains.
It
is
humorous
and
good-tempered.
It
can
be
with
me
whenever
I
feel
lonely.
My
ideal
robot
in
the
future
will
be

My

My

A
robot
is
a
very
human-like
servant
and
it
cares
for
us.
Robots
are
supposed
to
do
boring
and
difficult
jobs
that
humans
can
not
do
or
don’t
want
to
do.
We
can
imagine
a
future
in
which
robots
will
care
for
our
children
and
develop
friendships
with
us.
My
Android
My
android
is
called
Jack.
It
is
as
tall
as
a
real
man.
Strong
as
it
is,
Jack
is
tender
and
caring.
More
importantly,
it
is
humorous
and
good-tempered.
Sample
Jack
can
use
its
artificial
intelligence
to
attend
to
my
grandparents.
Not
only
can
it
do
some
housework,
such
as
mopping
the
floors
and
cooking,
but
also
it
can
read
newspapers
and
magazines
for
my
grandparents.
In
addition,
some
funny
stories
are
stored
in
its
“brain”,
so
whenever
it
is
necessary,
it
can
amuse
my
grandparents.
Although
it
cannot
do
shopping
for
my
grandparents,
it
is
really
helpful
in
keeping
my
grandparents
company.
In
the
future,
I
hope
it
can
be
better
programmed
and
do
more
things.

The

has
three
parts:
1.
The
main
heading,
which
is
written
larger
than
the

(梗概,
要旨)
of
the

in
a
few
words．

The

3.
The
article
itself
is
