三、阅读理解
A
Computers
are
useful
machines.
They
can
help
people
a
lot
in
their
daily
life.
For
example,
they
can
help
people
to
save
much
time
to
do
much
work,
and
they
can
help
people
to
work
out
many
problems
they
can’t
do
easily.
Our
country
asks
everyone
to
learn
to
use
computers
except
the
old
people.
Today
more
and
more
families
own
computers.
Parents
buy
computers
for
their
children.
They
hope
that
computers
can
help
them
to
improve
their
studies
at
school.
But
many
of
their
children
use
computers
to
play
games
and
watch
videos.
For
most
students,
computers
can
not
help
them
to
study
better
but
make
them
fall
behind.
So
computers
are
locked
in
boxes
by
parents.
In
some
other
countries,
even
some
scientists
also
hate
computers.
They
say
computers
let
millions
of
people
lose
their
jobs
or
bring
them
a
lot
of
trouble.
Will
computers
really
bring
trouble
to
people
or
can
they
bring
people
happiness?
It
will
be
decided
by
people
themselves!
21.
Why
do
we
say
the
computer
is
a
useful
machine?
A.
Because
our
country
asks
us
to
learn
to
use
it.
B.
Because
it
can
help
us
a
lot.
C.
Because
we
can
use
it
to
play
games.
D.
Because
it
can
help
us
to
find
jobs.
22.
What
do
many
parents
complain
about?
A.
They
complain
that
their
children
use
computers
to
play
games.
B.
They
complain
that
computers
let
them
lose
their
jobs.
C.
They
complain
that
computers
bring
them
a
lot
of
trouble.
D.
They
complain
that
computers
can’t
bring
them
happiness.
23.
In
this
passage
we
know
computers
______.
A.
also
bring
us
trouble
B.
bring
us
happiness
only
C.
are
hated
by
people
D.
are
bad
for
people’s
health
24.
Can
computers
really
help
children
to
study
better?
A.
Yes,
they
can.
B.
It’s
hard
to
say.
C.
No,
they
can’t.
D.
Of
course
not.
25.
How
do
you
understand
the
last
sentence
of
this
passage?
A.
It
means
computers
are
used
by
people.
B.
It
means
people
can
live
well
without
computers.
C.
It
means
one
must
decide
how
to
use
computers.
D.
It
means
computers
are
strange
machines.
B
The
Internet
is
becoming
important
in
our
life.
How
much
do
you
know
about
it?
The
following
questions
and
their
answers
will
help
you
to
know
more
about
the
Internet.
What
is
the
Internet?
The
Internet
is
a
large,
world-wide
collection
(聚集)
of
computer
networks
(网络).
A
network
is
a
small
group
of
computers
put
together.
The
Internet
is
many
different
kinds
of
networks
from
all
over
the
world.
These
networks
are
called
the
Internet.
If
you
have
learned
to
use
the
Internet,
you
can
have
a
lot
of
interest
on
the
World
Wide
Web
(网)
.
What
is
the
World
Wide
Web?
The
World
Wide
Web
has
been
the
most
popular
development
of
the
Internet.
It
is
like
a
big
electronic
(电子)
book
with
millions
of
pages.
These
pages
are
called
homepages.
You
can
find
information
about
almost
anything
in
the
world
on
these
pages.
For
example,
you
can
use
the
Internet
instead
of
a
library
to
find
information
for
your
homework.
You
can
also
find
information
about
your
favourite
sport
or
film
star,
talk
to
your
friends
or
even
do
some
shopping
on
the
pages.
Most
pages
have
words,
pictures
and
even
sound
or
music.
What
is
e-mail?
Electronic
mail
(e-mail)
is
a
way
of
sending
messages
to
other
people.
It’s
much
quicker
and
cheaper
than
sending
a
letter.
If
you
want
to
use
e-mail,
you
must
have
an
e-mail
address.
This
address
must
have
letters
and
dots

参考答案及解析
一、
1.
B
考查句子的时态。ago是一般过去时的标志，因此本句应该用一般过去时，空格处应填buy的过去式，故答案为B。
2.
D
考查动词用法。答语句意：它看起来很好。此处look为系动词，后接形容词作表语。
3.
B
考查动词辨析。agree指“同意（对方的意见或观点）”，问句给出的是一种正确的个人观点，因此要回答“I
agree.”，表示“我同意”。故选B。
4.
C
考查动词辨析。get是不及物动词，和表示地点的名词连用时，后要跟介词to；reach是及物动词，后直接跟表地点的名词；而arrive也是不及物动词，当arrive跟地点名词作宾语时，后要接介词in或at；go是不及物动词，和表示地点的名词连用时，后要跟介词to。所以选C。
5.
B
考查动词用法。mind后面的动词要用-ing形式。由答语中的please
do
it
now，可知答话人不介意，故选B。
6.
D
考查形容词辨析。问话人邀请对方看电影，答话人非常同意，并说电视节目太令人厌烦了。根据这四个选项，也只有boring符合上下文的含义。
7.
C
考查介词on的用法。介词on可用来表示“通过或借助某种媒体”，on
the
radio意为“通过收音机，借助收音机”，故选C。
8.
A
考查句子的时态和语态。本题是一个由how引导的宾语从句，作knows的宾语。由从句中的ago可知该宾语从句应该用一般过去时，因此C、D两项排除；由and可知两处空格之间是并列的关系，再
根据句意判断出应该用被动语态，因此B项排除。故选A。
9.
C
考查特殊疑问词。how
often用来提问频率，由答语“Once
a
month.”可知问句提问的是频率，故选C。
10.D
考查被动语态。从句中主语tickets是sell
out的承受者，所以用被动语态。在时间状语从句中，用一般现在时代替将来时，所以选D。
二、
11.
C
millions
of意为“数百万的”，A、B两项数值太小，D项表达错误。
12.
A
eat意为“吃”，空格后的it指代上文提到的rice，在此处作eat的宾语，因此应该用主动语态；又因为people作主语时谓语动词应该用复数形式，故填eat。
13.
C
anything意为“任何东西”，通常用于否定句和疑问句中，本句是一个否定句，因此填anything。
14.
A
由常识可知大米是草本植物，因此grass符合语境。
15.
D
grow意为“种植（庄稼等）”。
16.
A
come
from意为“来自（某地）”，相当于be
from。
17.
D
grow与rice之间是逻辑上的动宾关系，所以当rice作主语时，句子应该用被动语态；又因为谓语动词所表示的动作发生在过去，所以应该用过去式，因此填was
grown。
18.
D
others=other
scientists，与前面的some
scientists相对应。
19.
A
此处是固定短语come
from，时态上应该用一般过去时，因此填came。
20.
B
be
taken
to
sp.意为“被带到某地”，符合语境。
三、
21.
B
由文章第一段第一、二句“Computers
are
useful
machines.
They
can
help
people
a
lot
in
their
daily
life.”可知答案为B。
22.
A
由文章第二段第四句“But
many
of
their
children
use
computers
to
play
games
and
watch
videos.”可知答案为A。
23.
A
通读整篇文章可知，电脑有利也有弊，在给人们带来很多好处的同时，也带来很多麻烦。B、C、D三项都不全面，故答案为A。
24.
B
由文章第二段倒数第二句“For
most
students,
computers
can
not
help
them
to
study
better
but
make
them
fall
behind.”可知，电脑对于大多数学生来说，并不利于他们的学习，因此A项错误。C、D两项过于绝对，故答案为B。
25.
C
文章最后一句“It
will
be
decided
by
people
themselves!”的意思是“这将由人们自己来决定！”，与C项意思吻合，故答案为C。
26.
C
由文章第三段第一句“The
Internet
is
a
large,
world-wide
collection（聚集）of
computer
networks（网络）.”可知答案为C。
27.
A
由文章第五段第二句“It
is
like
a
big
electronic（电子）book
with
millions
of
pages.”可知答案为A。
28.
B
根据常识可知，A、C、D三项都是错误的，而B项正是对网上聊天的最佳解释，故答案为B。
29.
B
由文章最后一段第二句“It’s
much
quicker
and
cheaper
than
sending
a
letter.”可知答案为B。
30.
C
由文章最后一段第一句“Electronic
mail
(e-mail)
is
a
way
of
sending
messages
to
other
people.”可知，e-mail是electronic
mail的缩写形式，故答案为C。
