often
hear
that
computers
are
cold
or
not
like
people,
but
many
people
feel
more
comfortable
with
the
computer
than
with
another
person
in

life.
Computers
never
feel
tired
or
get
angry.
They
are
fast
and
reliable(可信賴的).To
some
students,
when
they
have
problems,
they
just
ask
computers
for
help
instead
or
teachers.
There
is
even
a
computer
program
about
solving
people's
psychological（心裡的）problems。The
program
becomes
popular
because
many
people
feel
uncomfortable
when
they
talk
about
their
problems
with
other
people.
The
programmer
is
worried
now，
because
people
are
always
using
this
program
instead
of
seeing
doctors.
He
wrote
the
program
only
to
show
that
computers
could
have
conversations
with
people.
However,
people
misunderstood
him.

Nowadays,
computers
play
a
more
and
more
important
role
in
our
lives.
What
will
happen
to
us
if
there
are
no
computers?
It
would
be
very
inconvenient
for
us.
However,
everything
has
two
sides.
So
do
computers.
On
the
one
hand,
computers
have
brought
a
lot
of
convenience
to
our
daily
lives.
We
can
use
Google
to
search
for
information
and
discuss
with
friends
on
QQ.
On
the
other
hand,
computers
truly
bring
some
problems.
Some
children
may
be
unaware
of
the
bad
effects
and
they
are
not
able
to
control
themselves,
so
they
often
spend
hours
on
the
computer
games
and
chatting
with
friends
about
some
useless
topics.
In
addition,
there
is
a
lot
of
harmful
information
online.
Let’s
use
computers
properly
to
improve
our
daily
lives.

Recently,
I
did
a
survey
on
how
the
students
in
our
class
use
computers
every
day.
The
following
is
the
result.
There
are
fifty
students
in
our
class.
Only
eight
of
us
use
computers
to
study
or
search
for
useful
information.
The
other
students
use
computers
for
fun.
Fifteen
students
chat
with
others
online.
Seventeen
students
play
games.
Ten
of
us
listen
to
music
an
see

In
my
opinion,
it
is
more
important
for
us
to
use
computers
for
study
than
for
fun.
So
if
we
can
use
computers
properly,
they
will
be
good
for
our

D项中，选出最佳选项。
A
I
fix
(修理)
computers
for
most
of
my
friends.
One
morning,
a
friend
came
for
help.
What
surprised
me
was
that
she
completely
disassembled
(拆解)
not
one
but
two
of
her
computers
because
they
couldn’t
connect
to
the
Internet.
I
thought
I
was
going
to
receive
two
computers,
but
I
was
completely
wrong.
What
I
was
given
was
a
huge
box
full
of
parts.
I
had
no
idea
why
she
did
all
of
this,
but
she
said
she
just
got
crazy
and
didn’t
stop
until
every
single
part
was
taken
apart.
My
friend
then
told
me
that
she
didn’t
need
two
computers,
so
if
I
just
made
one
computer
out
of
the
box
of
parts,
she
would
give
me
one
of
her
LCD
monitors.
Nine
hours
later,
I
had
one
fully-functional
computer.
Actually
it
wouldn’t
have
taken
that
long,
but
the
situation
(情况)was
so
funny
that
some
time
when
I
tried
to
put
the
parts
together,
I
laughed
too
hard
to
do
anything.
Finally
my
friend
left
one
monitor
for
me,
and
took
away
her
computer.
It
gave
me
a
feeling
of
happiness.
Usually
the
happiest
thing
for
me
was
not
the
reward,
but
what
I
did
for
others.
(
)

How
did
the

feel
when
the
friend
told
him
her
problem?
A.
Sad.
B.
Surprised.
C.
Happy.
D.
Nervous.
(
)
12.
What
can
we
learn
from
the
second
paragraph?
A.
The
friend
needed
two
new
computers.
B.
The
friend
usually
did
some
crazy
things.
C.
The
writer
found
he
couldn’t
help
his
friend.
D.
The
writer
realized
that
the
problem
was
different.

13.
What
does
the
underlined
word
“reward”
mean
in
Chinese?
A.回报
B.尊敬
C.挫折

of
the

is
NOT
true

the
writer?
A.

is
good
at
fixing
computers.
B.
He
could
have
fixed
the
computer
faster.
C.
He
fixed
the
computer
to
get
a
monitor.
D.
He
felt
happy
when
he
fixed
the
computer.
(
)
15.
What
can
we
learn
from
the
passage?
A.
Everyone
has
his
strong
point.
B.
Success
comes
from
hard
work.
C.
Drops
of
water
can’t
make
the

D.
The
true
happiness
is
helping
others.
B
Henry
Ford
was
born
on
July
30,
1863
in
Michigan.
At
an
early
age,
he
showed
an
interest
in
mechanical(机械的)
things.
In
1879,
sixteen-year-old
Ford
left
home
for
the
nearby
city
of
Detroit
to
work.
In
1891,
Ford
became
an
engineer
with
the
Edison
Illuminating
Company
of
Detroit.
Then,
he
became
the
Chief
Engineer
in
1893.
This
gave
him
enough
time
and
money
to
pay
attention
to
his
personal
experiments(实验).
Henry
Ford
realized
his
dream
of
producing
a
car
with
the
model
T(T型车)in1908.
This
car
started
a
new
era(时代)in
personal
transportation.
It
was
easy
to
operate,
and
immediately
became
a
huge
success.
By
1918,
half
of
all
cars
in
America
were
Model
Ts.
To
meet
the
growing
need
for
the
Model
T,
Ford’s
company
opened
a
large
factory.
In
this
factory
workers
worked
at
the
same
place
all
the
time.
A
belt
sent
the
parts
of
the
cars
to
workers.
They
added
one
part
to
each
car
as
it
moved
past
them
on
the
line.
The
introduction
of
the
moving
assembly
line(装配线)
greatly
improved
production
of
cars
and
cut
down
the
costs.
Ford’s
production
of
Model
Ts
made
his
company
the
largest
car
company
in
the
world.
The
company
began
building
the
world’s
largest
industrial
center
along
the
banks
of
the
Rouge
River
during
the
late
1910s
and
early
1920s.
By
September
1927,
all
steps
in
the
producing
process
took
place
at
the
vast
Rouge
Plant,
characterizing
Henry
Ford’s
idea
of
mass
production(大批量生产).

As
the
epidemic
(疫情)
keeps
improving,
life
in
China
is
slowly
returning
to
normal,
and
people
have
once
again
started
travelling.
From
Shanghai
to
Anhui
Province,
main
places
of
interest
in
China
welcomed
thousands
of
visitors
during
a
weekend.
At
the
end
of
March,
a
travel
survey(调查)
found
that
16%
of
15,
000
people
across
100
cities
in
China
would
be
ready
to
travel
in
May.
However,
most
of
the
people,
about
90%,
would
only
choose
to
travel
across
the
country.
According
to
the
survey,
about
61%
of
Chinese
travelers
said
that
they
were
going
to
travel
again
by
August.
Another
small
survey
of
1,
000
people
got
some
results
similar
to
the
first
survey’s.
In
this
survey,
about
77%
of
those
people
said
that
they
would
choose
to
stay
in
China
for
their
first
trip
after
the
epidemic.
Since
the
epidemic
is
getting
worse
and
worse
in
some
other
countries,
international
air
travel
has
nearly
stopped.
It’s
hardly
surprising
that
many
Chinese
travelers
would
choose
to
travel
at
home
because
China
has
successfully
got
the
epidemic
under
control.
Also,
the
two
surveys
showed
that
most
travelers
were
pretty
serious
about
the
safety
and
comfort
on
their
trips.
“Travelers
always
want
to
feel
safe
and
hope
there
is
no
virus
at
each
touching
point
along
the
journey,”
a
survey
leader
said.
(

21.
What
CANNOT
we
learn
about
the
first
survey?
A.
People
did
it
in
late
March.
B.
People
did
it
on
a
weekend.
C.
Only
people
in
China
took
part
in
it.
D.
More
than
10
thousand
people
took
part
in
it.
(
)
22.

second
survey,

many
people

China?
A.

610.
B.
About
770.
C.
About
13,500.

About

第二节
短文填空（共5小题；每小题1分，满分5分）阅读短文，并从下列方框里的六个句子中选择五个还原到原文中，使原文的意思完整、连贯。
A.
Water
makes
the
city
special,
but
it
is
also
a
big
problem.
B.
This
has
made
the
ice
of
the
Arctic
Ocean
melt.C.
Seawater
is
everywhere
around
the
city.D.
Water
pollution
is
another
problem
of
this
city.E.
Now
the
city
has
gone
down
by
23
centimeters.F.
People
in
Venice
move
from
place
to
place
by
boat.
A
city
without
cars
would
be
very
strange,
right?
But
Venice
is
such
a
city.
Venice
is
in
the
northeast
of
Italy.
I
wasn’t
built
on
land,
like
Beijing
or
Shanghai,
but
on
more
than
110
islands.
__26________
Even
so,
travel
isn’t
difficult.
The
waterways
have
always
been
the
best
ways
to
get
around.
There
are
117
waterways
and
more
than
400
bridges
that
can
guide
you
where
you
want
to
go.
__27________
They
like
to
enjoy
the
scenery
and
cool
summer
nights
while
taking
boat
trips.
They
can
talk
to
other
people
as
they
go
along.
Venice
grew
out
of
small
islands
in
saltwater
lakes
when
some
Italians
escaped
from
a
war
more
than
1,500
years
ago,
and
built
homes
there.
__28________
Once,
people
used
too
much
underground
water.
This
made
the
city
get
lower
little
by
little.
__29________
Another
problem
is
the
rising
seawater.
The
temperature
has
risen
over
the
years.
__30________
Every
year,
high
water
hit
the
city
in
autumn
and
winter.
When
a
lot
of
water
comes,
more
than
half
of
the
city
is
underwater.
Scientists
are
trying
different
ways
to
stop
the
city
from
getting
even
lower.

四、范文
On
my
thirteenth
birthday,
I
got
the
best
present
in
my
life
–
a
computer
from
my
father.
It
is
black
with
a
white
logo
in
the
middle
of
the
cover.
It
is
very
thin
and
has
a
14-inch
screen.
With
a
large
memory,
it
can
store
a
lot
of
documents,
pictures
and
videos.
The
computer
is
amazing.
However,
my
father
doesn’t
allow
me
to
use
it
for
a
long
time.
I
usually
use
it
when
I
need
to
search
for
some
information
about
my
homework.
When
the
weekend
comes,
I
can
play
games
on
it
for
an
hour.
Sometimes,
I
watch
a
movie
or
listen
to
some
music
on
it
to
relax
myself.
I
think
the
computer
is
very
useful
in
my
life.
I
will
surely
cherish
the
wonderful
present
forever.
