B
“Dad，”
I
say
one
day,
“let's
take
a
trip.
Why
don't
you
fly
out
and
meet
me？”
My
father
had
just
retired
after
27
years
as
a
manager
for
IBM.
His
job
filled
his
day,
his
thought,
and
his
life.
While
he
woke
up
and
took
a
warm
shower,
I
screamed
under
a
freezing
waterfall
in
Peru.
While
he
tied
a
tie
and
put
on
the
same
Swiss
watch,
I
rowed
a
boat
across
Lake
of
the
Ozarks.
My
father
sees
me
drifting
aimlessly,
nothing
to
show
for
my
33
years
but
a
passport
full
of
funny
stamps.
He
wants
me
to
settle
down,
but
now
I
want
him
to
find
an
adventure.
He
agrees
to
travel
with
me
through
the
national
parks.
We
meet
four
weeks
later
in
Rapid
City.
“What
is
our
first
stop？”
asks
my
father.
“What
time
is
it？”
“Still
don't
have
a
watch？”
Less
than
an
hour
away
is
Mount
Rushmore.
As
he
stares
up
at
the
four
Presidents
carved
in
granite
(花岗岩),
his
mouth
and
eyes
open
slowly,
like
those
of
a
little
boy.
“Unbelievable.”
he
says,
“How
was
this
done？”
A
film
in
the
information
center
shows
sculptor
Gutzon
Borglum
devoted
14
years
to
the
sculpture
and
then
left
the
final
touches
to
his
son.
We
stare
up
and
I
ask
myself,
“Would
I
ever
devote
my
life
to
anything？”
“No
directions,
no
goals”
I
always
used
to
hear
those
words
in
my
father's
voice.
Now
I
hear
them
in
my
own.
The
next
day
we're
at
Yellowstone
National
Park,
where
we
have
a
picnic.
“Did
you
ever
travel
with
your
dad？”
I
ask.
“Only
once，”
he
says,
“I
never
spoke
much
with
my
father.
We
loved
each
other
—
but
never
said
it.
Whatever
he
could
give
me,
he
gave.”
The
last
sentence
—
it's
probably
the
same
thing
I'd
say
about
my
father.
And
what
I'd
want
my
child
to
say
about
me.
In
Glacier
National
Park,
my
father
says,
“I've
never
seen
water
so
blue.”
I
have,
in
several
places
of
the
world.
I
can
keep
travelling.
I
realize
—
and
maybe
a
regular
job
won't
be
as
dull
as
I
feared.
Weeks
after
our
trip,
I
call
my
father.
“The
photos
from
the
trip
are
wonderful.”
he
says.
“We
have
got
to
take
another
trip
like
that
sometime.”
I
tell
him
I've
decided
to
settle
down,
and
I'm
wearing
a
watch.
5．We
can
learn
from
Paragraph
2
and
Paragraph
3
that
the
father
________.
A．liked
the
author's
collection
of
stamps
B．was
unhappy
with
the
author's
lifestyle
C．got
bored
with
his
job
D．followed
the
fashion
6．What
does
the
author
realize
at
Mount
Rushmore?
A．He
should
pursue
a
specific
aim
in
life.
B．He
should
learn
sculpture
in
the
future.
C．His
father
is
as
innocent
as
a
little
boy.
D．His
father
is
interested
in
sculpture.
7．What
could
be
inferred

and

father
from
the
end
of
the
story?
A．They
begin
to
change

attitudes
to
life.

Ⅲ.完形填空
I
have
neighbors
whose
adult
son
has
been
living
with
them
since
he
lost
his
job.
He
is
the
fifth
one
of
__1__
of
his
parents.
He
had
no
job
but
still
enjoyed
himself
because
he
had
a
dog
staying
together
with
him.
__2__，
his
dog
died
in
July
last
year.
That
__3__
hit
him
deeply,
which
was
understandable,
because
he
had
spent
most
of
his
time
walking
the
dog;
Besides,
he
had
made
friends
in
the
neighborhood
with
other
dog
__4__.
His
parents
didn't
__5__
his
idea
of
buying
another
dog
because
they
wanted
him
to
find
work.
It
was
a(n)
__6__
time
for
him;
I
could
see
he
was
lonely
__7__
his
dog.
All
he
could
do
was
help
his
mom
with
cooking
or
__8__
at
home.
I
wanted
to
help
him
get
rid
of
the
bad
feelings,
so
I
invited
him
to
__9__
the
dog
with
me.
We
also
__10__
in
some
picnic
activities
together.
Then
I
thought
maybe
something
else
would
help.
It
was
volunteering
(自愿做)
at
the
local
humane
society
(动物保护协会),
not
far
from
where
we
live.
It
took
only
several
__11__
for
us
to
get
there
by
bike.
At
first,
he
refused
to
volunteer
to
love
the
__12__
there.
However,
after
only
one
week,
he
began
to
__13__
me
excitedly
how
happy
he
was.
Now
he
seems
to
have
purposes
to
return
to
school
to
learn
zoology
(动物学)
and
study
animals
in
the
future.
I
feel
happy
that
he
has
__14__.
I
am
more
pleased
that
he
feels
__15__
and
valued.
And
that
is
so
important
to
all
of
us.

Ⅱ.阅读理解
A
Many
people
over
60
years
of
age
in
the
UK
are
spending
their
later
years
taking
up
new
hobbies
and
activities,
according
to
research
from
Age
UK.
71
percent
of
those
over
60
years
old
are
meeting
new
challenges
like
learning
a
foreign
language,
dancing
in
the
dance
floor,
or
even
taking
part
in
outdoor
activities
like
bungee
jumping
and
mountain
climbing.
The
new
survey
looks
at
attitudes
(态度)
towards
later
life
in
people
aged
18
and
above.
With
the
positive
(积极的)
attitudes
of
many
of
those
aged
60
and
above
who
describe
their
lifestyle
as
interesting
(38
percent),
varied
(各种各样的)
(42
percent),
fun
(20
percent)
and
satisfying
(24
percent),
it
shows
the
nation
that
growing
older
does
not
mean
that
interests
and
hobbies
should
stop.
The
old
people
are
doing
what
they
enjoy,
celebrating
later
life
and
enjoying
all
that
it
can
offer.
This
is
totally
different
from
some
younger
people's
ideas
of
old
age
as
boring
and
slow?paced.
Among
those
are
dancers,
a
91?year?old
bodybuilder
and
a
81?year?old
singing
leading
lady.
Many
of
them
are
people
who
have
been
directly
helped
by
Age
UK.
Michelle
Mitchell,
Charity
Director
at
Age
UK
said,
“Through
our
research,
we
hope
to
show
another
side
of
growing
older
and
encourage
people
of
all
ages
to
take
up
some
hobbies.
One
in
five
says
that
they
have
felt
more
comfortable
in
their
own
skin
since
they
reached
60
years
of
age,
and
this
confidence
helps
to
give
people
the
drive
to
try
the
activities
they
have
always
wanted
to
try.”

many

more
and
more
common,
the
market
is
growing
for
biometric
(生物测量)
technologies
—
like
fingerprint
scans
—
to
keep
others
out
of
private
e?spaces.
At
present,
these
technologies
are
still
expensive,
though.
Researchers
from
Georgia
Tech
say
that
they
have
come
up
with
a
low?cost
device
(装置)
that
gets
around
this
problem:
a
smart
keyboard.
This
smart
keyboard
precisely
measures
the
cadence
(节奏)
with
which
one
types
and
the
pressure
fingers
apply
to
each
key.
The
keyboard
could
offer
a
strong
layer
of
security
by
analyzing
things
like
the
force
of
a
user's
typing
and
the
time
between
key
presses.
These
patterns
are
unique
to
each
person.
Thus,
the
keyboard
can
determine
people's
identities,
and
by
extension,
whether
they
should
be
given
access
to
the
computer
it's
connected
to
—
regardless
of
whether
someone
gets
the
password
right.
It
also
doesn't
require
a
new
type
of
technology
that
people
aren't
already
familiar
with.
Everybody
uses
a
keyboard
and
everybody
types
differently.
In
a
study
describing
the
technology,
the
researchers
had
100
volunteers
type
the
word
“touch”
four
times
using
the
smart
keyboard.
Data
collected
from
the
device
could
be
used
to
recognize
different
participants
based
on
how
they
typed,
with
very
low
error
rates.
The
researchers
say
that
the
keyboard
should
be
pretty
straightforward
to
commercialize
and
is
mostly
made
of
inexpensive,
plastic?like
parts.
The
team
hopes
to
make
it
to
market
in
the
near
future.
4．Why
do
the
researchers
develop
the
smart
keyboard?
A．To
reduce
pressure
on
keys.
B．To
improve
accuracy
in
typing.
C．To
replace
the
password
system.
D．To
cut
the
cost
of
e?space
protection.
5．What
makes
the
invention
of
the
smart
keyboard
possible?
A．Computers
are
much
easier
to
operate.
B．Fingerprint
scanning
techniques
develop
fast.
C．Typing
patterns
vary
from
person
to
person.
D．Data
security
measures
are
guaranteed.
6．What
do
the
researchers
expect
of
the
smart
keyboard?
A．It'll
be
environment?friendly.
B．It'll
reach
consumers
soon.
C．It'll
be
made
of
plastics.
D．It'll
help
speed
up
typing.
7．Where
is
this
text
most
likely
from?
A．A
diary.
B．A

Ⅱ.阅读理解
A
Train
travel
is
becoming
more
popular.
Amtrak,
the
U．S.
national
passenger
rail
company,
reports
that
ridership
(公共交通乘客人数)
continues
to
grow
each
year.
The
passenger
kilometres
and
numbers
of
passenger
journeys
are
also
increasing.
There's
every
reason
to
believe
train
travel
will
continue
to
attract
more
passengers
as
fuel
prices
climb，
As
you
plan
your
vacation,
you'll
need
to
consider
the
advantages
and
disadvantages
of
train
travel.
Here
are
some
things
that
you
need
to
keep
in
mind.
Train
travel
is
fast
and
direct
between
major
cities,
especially
in
countries
with
high?speed
trains.
It's
relatively
easy
to
book
a
train
trip.
In
many
countries,
you
can
book
your
tickets
online
or
go
to
a
train
station
to
buy
them.
For
single
or
couple
travelers,
traveling
by
train
can
be
much
less
expensive
than
renting
a
car,
especially
when
you
consider
the
cost
of
fuel
and
tolls
(通行费)．
However,
train
schedules
may
not
match
your
preferred
travel
times
and
days,
so
you
might
have
to
change
your
trip.
This
is
especially
true
for
long?distance
train
travel
in
the
US.
You
may
have
to
get
off
the
train
at
midnight
in
a
small
station
in
an
empty
town
in
order
to
make
a
train
connection.
You
need
to
bring
your
own
food
and
drink
into
the
train
as
the
food
and
drink
served
on
trains
can
be
expensive.
Conditions
on
the
train
may
be
crowded,
dirty
and
uncomfortable,
especially
at
busy
travel
times
or
in
developing
countries.
In
the
end,
you'll
need
to
do
some
research
on
train
ticket
prices,
check
schedules
against
your
own
plan
and
weigh
the
advantages
and
disadvantages
of
train
travel
against
your
personal
preferences.
1．What
may
be
one
cause
of
train
travel
increase
from
the
text?
A．More
new
railways.
B．Growing
fuel
prices.
C．Improved
train
schedules.
D．Convenient
food
service.
2．What
are
the
advantages
of
train
travel
according
to
the
text?
a．It
is
the
cheapest
mode
of
travel.
b．It
is
easy
to
book
a
train
ticket
online.
c．It
is
cheaper
for
single
or
couple
travelers.
d．It
is
fast
and
direct
between
big
cities.
e．It's
easy
to
bring
your
own
food
and
drink.
A．abe
B．abd
C．cde
D．bcd
3．What
problem
might
passengers
meet
when
traveling
by
train?
A．They
might
have
to
change
a
train
midway
for
a
long
distance
trip.
B．They
might
have
to
pay
for
the
fuel
and
tolls.
C．They
might
have
to
exchange
another
train
in
a
crowded
town.
D．They
might
have
to
book
train
tickets.
B
Travel
is
one
of
the
most
exciting
experiences
a
human
being
can
have.
Imagine
how
amazed
Italian
traveler
Marco
Polo
must
have
felt
when
he
found
himself
on
Chinese
soil,
seeing
a
way
of
life
quite
different
from
anything
he'd
seen
before.
And
how
great
must
it
have
been
to
listen
to
Zhang
Qian
when
he
returned
to
China
from
his
journey
through
Central
Asia
and
West
Asia?
His
brain
must
have
been
packed
with
everything
he'd
seen
and
heard,
leading
to
the
founding
of
the
Silk
Road.
Some
people
have
traveled
all
over
the
world,
and
travel
is
a
way
of
life
to
them.
They
perhaps
know
what
to
expect
before
they
travel.
That's
why
the
best
travel
is
when
it's
for
the
first
time.
Imagine
a
person
who
has
always
wanted
to
travel
to
the
United
States.
Of
course,
they've
probably
seen
the
Statue
of
Liberty
a
thousand
times
on
TV,
and
the
White
House,
and
all
the
other
famous
sights.
But
none
of
that
would
compare
to
the
thrill
of
looking
out
of
the
cabin
window
as
the
plane
lands,
watching
the
cities
and
streets
of
the
real
America
come
into
view.
Although
travel
is
often
just
for
recreation,_it's
also
educational.
We
may
not
know
that
we
are
getting
an
education,
but
we
still
are.
We're
learning
every
day:
new
words
in
a
new
language,
new
people,
and
new
ways
of
life.
But
this
learning
takes
place
in
the
school
of
the
world,
not
the
classroom.
One
of
the
lessons
we
learn
is
undoubtedly
a
moral
one.
As
we
get
to
know
foreign
places,
we
come
to
understand
that
there
are
many
different
ways
to
live，and
that
the
way
we
live
isn't
necessarily
the
best
way.
The
British
politician
Benjamin
Disraeli
summed
this
up
well
when
he
said,
“Travel
teaches
toleration.”
4．The
writer
uses
Marco
Polo
and
Zhang
Qian
as
examples
to
________.
A．explain
how
the
Silk
Road
was
founded
B．present
travel
as
an
amazing
experience
C．show
how
the
way
people
travel
has
changed
D．describe
important
cultural
exchanges
in
history
5．The
underlined
word
in
paragraph
4
probably
means
________.
A．learning
B．knowledge
C．fun
D．risk
6．According
to
the
last
two
paragraphs,
the
writer
believes
that
________.
A．traveling
should
be
included
in
formal
education
B．traveling
improves
people's
confidence
in
their
lifestyle
C．a
foreign
journey
may
raise
people's
cultural
understanding
D．there
is
more
to

than

Ⅲ.阅读七选五
