things
like
Lei
Feng.
他像雷锋一样做了许多好事。
as说明同一关系，指身份，意为“作为,当作”。
e.g.
Don't
treat
me
as
a
child.I'm
15.
别把我当小孩子了，我都十五岁了。
as
还有“像，
按照”的意思。

三．阅读理解。
How
soon
will
robots
become
so
clever
that
they
will
be
able
to
do
jobs
which
human
can
do,
such
as
teaching
language
or
looking
after
patients
in
hospital
Some
experts
believe
this
will
happen
in
twenty
years.
UAS,
one
London
company,
has
already
developed
a
kind
of
machine.
①It
can
be
used
as
“home-helps”
for
old
people.
It
can
also
do
such
things
as
cooking
eggs
and
cleaning
the
floor.
The
company
says
that
the
machine
will
accept
simple
voice
instructions
and
that
the
machine
will
be
controlled
by
a
latest
IBM
microcomputer
(微机).
Mr.
Henry,
the
director
of
UAS,
believes
that
his
company
will
develop
the
clever
robots
for
using
in
industry.
By
this
time
they
will
begin
to
sell
the
machines
into
ordinary
homes.
Robots
can
do
much
housework,
such
as
washing
dishes,
cleaning
the
house
and
cooking
meals.
②By
the
way,
the
price
of
them
may
be
as
little
as＄1,000.
But
Dr.
Sandra
believes
we
have
a
long
way
to
develop
truly
intelligent
(真正智能化的)
machines.
She
says,
it
can
cook
an
egg.
But
if
one
of
eggs
is
bad,
it
will
still
cook.
If
you
ask
a
robot
to
do
something
unusual
that
needs
a
man
to
think,
a
robot
is
useless.
根据短文内容，回答下列问题。
1.
How
soon
do
some
experts
believe
robots
will
be
able
to
do
jobs

第①句中
“home-helps”
的意思是(
)。
A.

B.

C.
帮助照看老人的佣人
D.
家政服务
4.
