robot
like
An
inventor
has
cre
( http: / / www.21cnjy.com )ated
his
perfect
woman,
a
robot
who
can
do
the
cleaning,
remember
his
favourite
drink
and
read
him
the
newspaper
headlines. LeTrung,
33,
has
spent￡14,000
creating
Aiko,
who
he
describes
as
"in
her
20s"
with
a
32,
23,
33
figure,
shiny
hair
and
delicate
features.
She
can
speak
English
and
Japanese. MrTrung
said
he
has
never
had
time
to
find
a
real
partner
–
so
he
designed
and
created
his
ideal
woman
using
the
latest
technology. He
said:
"Aiko
is
what
happens
when
science
meets
beauty. "I
want
to
make
her
look,
feel
and
act
as
human
as
possible
so
she
can
be
the
perfect
companion. "I
talk
to
her
a
lot,
and
hope
to
improve
her
knowledge.”
So
far
she
can
understand
and
speak
13,000
different
sentences
in
English
and
Japanese,
so
she's
already
fairly
intelligent. "Aiko
recognizes
faces
and
says
hello
when
any
of
my
family
come
around
to
visit.
She
helps
me
pick
what
to
have
for
dinner
and
knows
what
drinks
I
like. "She
even
helps
me
with
directions
when
we're
going
somewhere.
"She
doesn't
need
holidays,
food
or
rest
and
she
will
work
almost
24-hours
a
day.
She
is
very
patient
and
never
complains.
She
is
the
perfect
woman."

Computer
programmer
( http: / / www.21cnjy.com )David
Jones
makes
35,000
pounds
a
year
designing
new
computer
games,
yet
he
cannot
find
a
bank
prepared
to
let
him
have
a
credit
card
(信用卡).
Instead,
he
has
been
told
to
wait
another
two
years,
until
he
is
18.
The
16-year-ol
( http: / / www.21cnjy.com )d
boy
works
for
a
small
firm
in
Liverpool,
where
the
problem
of
most
young
people
of
his
age
is
finding
a
job.
David’s
firm
puts
two
new
games
on
the
home
market
each
month.
But
David’s
bigges
( http: / / www.21cnjy.com )t
headache
is
what
to
do
with
his
money.
In
spite
of
his
salary,
made
by
inventing
new
programs
within
a
quite
short
period
of
time,
the
bonus
payments
and
profit-sharing
(奖金和分红),
he
cannot
drive
a
car,
get
some
money
from
a
bank
to
buy
a
house,
or
get
credit
cards.
He
lives
with
his
p
( http: / / www.21cnjy.com )arents
in
their
house
in
Liverpool,
where
his
father
is
a
bus
driver.
His
firm
has
to
pay
￡150
a
month
in
taxi
fares
to
get
him
the
five
miles
to
work
and
back
every
day
because
David
cannot
drive.
David
got
his
( http: / / www.21cnjy.com )job
with
the
firm
a
year
after
leaving
school
with
six
0-levels
and
working
for
a
time
in
a
computer
shop.
“I
got
the
job
because
the
people
who
run
the
firm
knew
I
had
already
written
some
programs,”
he
said.
“I
suppose
35
( http: / / www.21cnjy.com ),000
pounds
sounds
a
lot
but
actually
that’s
not
good
enough.
I
hope
it
will
come
to
more
than
that
this
year.”
He
spends
some
of
his
money
on
records
and
clothes,
and
gives
his
mother
20
pounds
a
week.
But
most
of
his
spare
time
is
spent
working.
“Unfortunately,
compu
( http: / / www.21cnjy.com )ting
was
not
part
of
our
studies
at
school,”
he
said.
“But
I
had
been
studying
it
in
books
and
magazines
for
four
years
in
my
spare
time.
I
know
what
I
wanted
to
do
and
never
considered
staying
on
at
school.
Most
people
in
this
business
are
fairly
young,
anyway.”
David
added,
“I
would
( http: / / www.21cnjy.com )like
to
earn
a
million
and
I
suppose
early
retirement
(退休)
is
a
possibility.
You
never
know
when
the
market
might
disappear.”

二．完形填空
About
a
year
ago
( http: / / www.21cnjy.com ),
I
went
to
stay
at
a
Detroit
hotel.
I
didn’t
want
to
11
too
much
money
with
me,
so
I
12
the
desk
clerk
to
put
a
hundred-dollar
bill
in
the
safe
for
13
.The
next
morning,
however,
the
clerk
said
that
he
knew
nothing
about
my
money.
I
didn’t
have
any
proof(证据)
14
I
had
given
the
man
the
money.
There
was
clearly
15
left
to
do
but
go
to
the
nearest
lawyer
at
once.
The
lawyer
16
me
to
return
to
the
hotel
with
him
and
give
17
hundred-dollar
bill
to
the
clerk.
18
we
did.
An
hour
later,
I
went
back
to
the
desk
and
asked
for
my
money
together
with
the
lawyer.
19
I
had
the
lawyer
as
an
eyewitness
(证人)
to
the
20
hundred-dollar
bill,
the
clerk
could
not
__21___
he
knew
nothing
about
it.
Another
hour
late
( http: / / www.21cnjy.com )r,
I
put
the
second
part
of
the
lawyer’s
plan
into
action.
This
time
both
the
lawyer
and
I
went
to
the
_22___to
ask
for
the
hundred-dollar
once
again.
No
matter(不管)
23____I
said,
the
clerk
who
kept
my
bill
_24___
that
he
had
given
it
to
me.
I
said
it
was
not_25___.
The
lawyer
said
to
him,
“I_26___this
gentleman
give
you
a
hundred-dollar
bill.
If
you
don’t
hand
it
in
immediately,
I
will
be
forced
to
call
the
_27___
.”
Now
the
clerk
felt
quite
__28___
,
so
he
gave
me
back
the
first
hundred-dollar
bill.
“I
don’t
know
( http: / / www.21cnjy.com )
_29____
to
thank
you
enough
for
getting
my
money
back,”
I
said
to
the
lawyer.
And
what
do
you
suppose
he
answered
He
said,
“Oh,
don’t
_30___
me.
That
will
be
one
hundred
dollars,
please.”

三．阅读理解
A
At
one
time,
c
( http: / / www.21cnjy.com )omputers
were
expected
largely
to
remove
the
need
for
paper
copies
of
documents(文件)
because
they
could
be
stored
electronically.
But
for
all
the
texts
that
are
written,
stored
and
sent
electronically,
a
lot
of
them
are
still
ending
up
on
paper.
It
is
difficult
to
me
( http: / / www.21cnjy.com )asure
the
quantity
of
paper
used
as
a
result
of
use
of
Internet-connected
computers,
although
just
about
anyone
who
works
in
an
office
can
tell
you
that
when
e-mail
is
introduced,
the
printers
start
working
overtime.
“I
feel
in
my
bones
this
revolution
is
causing
more
trees
to
be
cut
down,”
says
Ted
Smith
of
the
Earth
Village
Organization.
Perhaps
the
best
( http: / / www.21cnjy.com )sign
of
how
computer
and
Internet
use
pushes
up
demand
for
paper
comes
from
the
high-tech
industry
itself,
which
sees
printing
as
one
of
its
promising
new
markets.
Several
Internet
companies
have
been
set
up
to
help
small
businesses
print
quality
documents
from
a
computer.
Earlier
this
week
Hewlett-Packard
Co.
announced
a
plan
to
develop
new
technologies
that
will
enable
people
to
print
even
more
so
they
can
get
a
hard
copy
of
a
business
document,
a
medical
record
or
just
a
one-line
e-mail,
even
if
they
are
nowhere
near
a
computer.
As
the
company
sees
it,
the
more
use
of
the
Internet
the
greater
demand
for
printers.
Does
all
th
( http: / / www.21cnjy.com )is
mean
environmental
concerns(环境问题)
have
been
forgotten
Some
activists
suggest
people
have
been
led
to
believe
that
a
lot
of
dangers
to
the
environment
have
gone
away.
I
guess
people
believe
that
the
problem
is
taken
care
of,
because
of
recycling(回收利用),
said
Kelly
Quirke,
director
of
the
Rainforest
Action
Network
in
San
Francisco.
Yet
Quirke
is
hopeful
that
high-tech
may
also
prove
helpful.
He
says
printers
that
print
on
both
sides
are
growing
in
popularity.
The
action
( http: / / www.21cnjy.com )group
has
also
found
acceptable
paper
made
from
materials
other
than
wood,
such
as
agricultural
waste.
31.
The
growing
de
( http: / / www.21cnjy.com )mand
for
paper
in
recent
years
is
largely
due
to
____.
the
rapid
development
of
small
businesses
the
opening
up
of
new
markets
the
printing
of
high
quality
copies
the
increased
use
of
the
Internet
32.
Environmentalis
( http: / / www.21cnjy.com )ts
believe
one
possible
way
of
dealing
with
the
paper
situation
is
____.
to
encourage
printing
more
quality
documents
to
develop
new
printers
using
recycled
paper
to
find
new
materials
for
making
paper
to
plant
more
fast-growing
trees
33.
Hewlett-Packard
( http: / / www.21cnjy.com )Co.
has
decided
to
develop
new
technologies
because
____.
people
are
concerned
about
the
environment
printers
in
many
offices
are
working
overtime
small
companies
need
more
hard
copies
they
see
a
growing
market
for

Your
friend
might
( http: / / www.21cnjy.com )be
in
Australia
or
maybe
just
down
the
road,
but
they
are
all
just
a
few
clicks
away.
Life
has
changed
for
millions
of
teenagers
across
the
world
who
now
make
friends
online.
Whether
you
use
chat
room,
QQ,
MSN
or
ICQ,
you
are
part
of
virtual
community.
“I
rarely
talk
with
m
( http: / / www.21cnjy.com )y
parents
or
grandparents,
but
I
talk
a
lot
with
my
old
friends
on
QQ,”
said
Fox’s
Shadow,
the
online
nickname
used
by
a
Senior
2
girl
in
China.
“Eight
percent
of
my
classmates
use
QQ
after
school.”
QQ
is
the
bigg
( http: / / www.21cnjy.com )est
messaging
service
in
China.
A
record
4
million
people
use
it
one
Saturday
night
in
October,
according
to
Tencent,
the
company
which
developed
QQ.
And
Fox’s
Shadow
( http: / / www.21cnjy.com )
might
well
have
been
one
of
them.
“I
log
in
on
Friday
nights,
and
Saturdays
or
Sundays
when
I
feel
bored.
I
usually
spend
about
10
hours
chatting
online
every
week,”
she
said.
“But
I
rarely
talk
with
strangers,
especially
boys
or
men.”
Even
though
s
( http: / / www.21cnjy.com )he
likes
chatting,
she
is
careful
about
making
friends
with
strangers
online.
“You
don’t
know
who
you’re
talking
to.
You
should
always
be
careful
about
who
you
trust
online.”
Many
people
would
lik
( http: / / www.21cnjy.com )e
to
meet
offline
when
they
feel
they
have
got
to
know
someone
very
well.
Fox’s
Shadow
once
met
one
of
her
online
friends
face
to
face.
It
was
a
girl
who
was
a
comic
fan
like
herself
and
they
went
to
a
comic
show
together.
However,
not
all
tee
( http: / / www.21cnjy.com )nagers
have
been
so
fortunate.
At
the
beginning
of
this
year,
a
17-year-old
girl
in
Liaoning
Province
was
raped
after
meeting
a
friend
she
had
found
on
QQ.
A
16-year-old
Beijing
( http: / / www.21cnjy.com )
boy,
known
online
as
Bart
Simon,
dislikes
QQ
users.
“I
used
to
chat
on
QQ,
but
I
found
that
most
people
were
talking
nonsense.”
he
said.
Now
he
chats
online
in
English,
using
MSN.
“I
only
chat
online
because
I’ve
got
friends
in
Japan,
the
US
and
Singapore,”
he
said,
“I
want
to
learn
more
about
foreign
cultures.”
But
he
spends
little
time
chatting
as
he
sees
it
as
a
waste
of
time
and
money.
“If
you
are
re
( http: / / www.21cnjy.com )ally
addicted
to
it
sometimes
you
just
can’t
concentrate
in
class,”
he
said.
“And
the
friends
in
your
real
life
are
always
more
important
than
those
so-called
friends
you
meet
online.”

书面表达
Computers
and
Our
Life
Good
morning,
ladi
( http: / / www.21cnjy.com )es
and
gentlemen!
I’m
very
glad
to
be
here
today
to
give
you
a
short
speech
about
computers
and
our
life.
I
hope
you
will
like
it.
With
recent
econo
( http: / / www.21cnjy.com )mic
development,
computers
have
become
more
and
more
important
in
our
life.
First,
we
can
work
more
efficiently.
Second,
we
can
go
online
and
get
connected
with
our
friends.
Third,
if
we
need
any
information,
we
can
use
the
computer
to
look
for
it
on
the
Internet.
It
is
convenient
and
easy.
A
coin
has
two
sides,
though.
Computers
have
some
bad
effects
as
well.
For
example,
some
students
have
wasted
a
lot
of
valuable
study
time
playing
games.
Also,
people
who
use
computers
too
much
can
become
near-sighted.
In
short,
( http: / / www.21cnjy.com )I
hold
the
view
that
we
should
avoid
the
bad
effects
they
may
bring,
while
making
good
use
of
computers.
