二、完型填空
Technology
has
made
life
much
easier
for
children
today.
It
is
16
for
them
to
play,
to
listen
to
music,
and
to
17
in
touch
with
their
friends.
18
the
help
of
technology,
there
seems
to
be
nothing
that
children
can't
do
now.
Technology
also
helps
19
to
know
more
about
their
children.
For
example,
if
a
child
is
given
a
mobile
phone
with
a
tracking(追踪)
device,
his
parents
can
find
out
20
he
is
going
with
the
help
of
the
mobile
phone.
However,
there
are
also
some
bad
21
of
technology.
For
example,
it
has
become
easier
for
bad
people
to
get
in
touch
with
children
with
the
help
of
technology.
They
can
find
personal
information
about
children
through
special
ways
on
the
22
.
So
it
is
very
important
for
parents
to
23
their
children
to
keep
personal
information
safe
while
surfing
the
Internet.
Besides
this,
there
is
another
bad
thing
about
technology.
Children
now
24
less
time
doing
exercise
than
before.
They
are
too
25
playing
online
games.
They
can
even
play
computer
games
all
day
long.
If
you
don't
push
them
out
of
the
door,
they
won't
volunteer
to
go
out
and
play.
This
is
not
good
for
their
health.
Therefore,
teaching
children
the
right
way
to
make
good
use
of
technology
is
very
important.
16．A．easier
B．more
difficult
C．more
important
D．harder
17．A．lose
B．make
C．keep
D．contact
18．A．For
B．Under
C．With
D．Over
19．A．teachers
B．friends
C．parents
D．classmates
20．A．when
B．whom
C．why
D．where
21．A．sides
B．places
C．choices
D．winds
22．A．phone
B．TV
C．radio
D．Internet
23．A．teach
B．learn
C．punish
D．lend
24．A．pay
B．take
C．cost
D．spend
25．A．lazy
B．free
C．busy
D．hard-working
三、阅读理解
A
robot
is
a
machine.
But
it
is
not
just
any
machine.
It
is
a
special
kind
of
machine.
It
is
a
machine
that
moves.
It
follows
instructions.
The
instructions
come
from
a
computer.
Because
it
is
a
machine,
it
does
not
make
mistakes.
And
it
does
not
get
tired.
And
it
never
complains.
Unless
you
tell
it
to!
Robots
are
all
around
us.
Some
robots
are
used
to
make
things.
For
example,
robots
can
help
make
cars.
Some
robots
are
used
to
explore
dangerous
places.
For
example,
robots
can
help
explore
volcanoes.
Some
robots
are
used
to
clean
things.
These
robots
can
help
vacuum
your
house.
Some
robots
can
even
recognize
words.
They
can
be
used
to
help
answer
telephone
calls.
Some
robots
look
like
humans.
But
most
robots
do
not.
Most
robots
just
look
like
machines.
Long
ago,
people
imagined
robots.
Over
2,000
years
ago,
a
famous
poet
imagined
robots.
The
poet's
name
was
Homer.
His
robots
were
made
of
gold.
They
cleaned
things
and
they
made
things.
But
they
were
not
real.
They
were
imaginary.
Nobody
was
able
to
make
a
real
robot.
The
first
real
robot
was
made
in
1961.
It
was
called
Unimate.
It
was
used
to
help
make
cars.
It
looked
like
a
giant
arm.
In
the
future,
we
will
have
even
more
robots.
They
will
do
things
that
we
can't
do.
Or
they
will
do
things
that
we
don't
want
to
do.
Or
they
will
do
things
that
are
too
dangerous
for
us.
Robots
will
help
us
fight
fires.
They
will
help
us
fight
wars.
They
will
help
us
fight
sickness.
They
will
help
us
discover
things.
They
will
help
make
life
better.

参考答案
1．C
【解析】
句意：——汤姆怎么了？他看起来很伤心。——哦，他的手机意外被丢在出租车里了。
考查副词词义辨析。completely完全地；quietly安静地；accidentally意外地；naturally自然地。根据常识可知，丢手机应是意外。故选C。
2．C
【解析】
句意：那个城镇陆地的五分之二覆盖着树和草。
考查分数和主谓一致。英语中分数的表达，分子用基数词，分母用序数词，分子大于一时，分母加s，故“五分之二”应表达为two
fifths，排除A和B；分数+of+名词在句中作主语，谓语动词的单复数与名词形式一致，“land”为单数，故选C。
3．B
【解析】
句意：——真是乱七八糟！共享单车被扔的到处都是。——让我们把它们收集起来，放到正确的位置，以便它们可以被方便地使用。
考查so
that引导目的状语从句。unless除非；so
that以便；because因为；so
long
as只要。根据“they
can
be
used
conveniently.”
可知，把共享单车放到正确位置的目的是为了被人们方便地使用。故选B。
4．C
【解析】
句意：——小姐，你最喜欢哪一条裙子？——对不起，我现在还无法决定买哪一条。
考查固定结构。decide决定，及物动词需接宾语；which
one意为“哪一件”，“疑问词+动词不定式”用作宾语；which
one
to
buy意思是“买哪一件”，作decide的宾语。结合选项，故选C。
5．C

发现；industry工业。根据句意可知，屠呦呦是科学家，因此应该是她的发现拯救了很多人的生命，故选C。
考点：考查名词词义辨析。

考查连词辨析。until直到；if如果；unless除非，根据主句“Food

easily”和从句“it
isn’t
put
in
the
fridge”可知，应该是如果食物不放进冰箱很容易变质，故选B。
7．C
【解析】
句意：你的故乡真漂亮！空气质量和三亚的一样好。that指已提到过或已知的某类人或事物；考查代词辨析。it是代指上文提及的同一个东西；one指代上文提到的同类事物中的某一个，one是泛指，the
one是特指。这里的代词代指air
quality,
指代上文提到的某类事物，用that。其后经常跟介词短语。故选C。
8．C
【解析】
试题分析：考查形容词与副词辨析。句意:
——汤姆,
杰克和比尔,
谁做作业
?
——比尔。根据后面的三个人可知此空应用最高级形式,

9．C
【分析】
【考点定位】考查定语从句的用法。
【解析】
试题分析：句意：这里有属于你的东西吗？此题考查定语从句，因为是anything是不定代词，故用引导词that,和固定短语belong
to属于。belong是个动词，不能和is连用。还有that作主语，应按第三人称单数处理。根据句意，故选C。
10．C
【解析】
句意：——看，海伦办公室的那个灯还亮着。——可能她还没有完成工作。根据标志词yet可以判断用现在完成时。句意：或许她还没完成她的工作。根据Look，the
light
is
still
on
in
Helen’s
office．可知她办公室的等还亮着，因此现在她还没有完成工作，故用现在完成时，故选C。
11．A
【解析】
句意：——从你家到学校有多远?——步行大约十分钟。
考查特殊疑问词辨析。How
far多远；How
long多长；How
many多少；How
much多少、多少钱。根据答语It’s
about
ten
minutes’
walk.步行大约十分钟，可知上文是问从你家到学校有多远，所以用how
har提问，故答案选A。
【点睛】
How
far多远，是对距离的提问；How
long多长，是对长度或一段时间的提问；How
many多少，是对可数名词数量的提问；How
much多少，是对不可数数量或价格进行提问。本题根据答语，可知是问距离的，所以用how

本题考查动词。suggest建议，是及物动词；agree同意，是不及物动词；realize实现，是及物动词；plan计划，是不及物动词。此处接宾语从句，用及物动词，根据Do
you

any
good
ideas?可知此处表示询问建议，故选A。
14．C
【解析】
句意：——看那个人。我想他一定是李平的父亲。——我不这么认为。李平的父亲戴眼镜，但他不戴。
考查口语交际。I'm

think
so我不这样认为；I
don't
know我不知道。由答语的后一句“Li

think
so符合语境，故选C。

六．范文：
Dear
editor,
As
is
known
to
us①,
more
and
more
people
would
rather
watch
TV
than①
read
books.
Books
or
TV?
I
prefer
books
because
books
have
more
advantages
than
TV.
First,
books
are
easy
to
carry
and
need
no
electricity,
which
means
we
can
read
them
almost
anywhere①.
Second,
when
we
enjoy
stories
written
by
famous
writers，our
writing
skills
can
be
improved.
Besides,
books
can
be
kept
for
a
long
time.②
If
we
think
one
book
is
interesting,
we
can
read
it
over
and
over
again①.
Books
also
help
us
think
deeper,
for
we
may
ask
ourselves
questions
as
we
read.
Let's
spend
some
time
in
reading.
The
more
we
read,
the
more
we
get.①
Yours,
Li
Hua

名师点评：
◆本文包含了书信类作文的三个基本要素：收信人(文章的开头)；书信的内容(正文部分)以及写信人(文章的落款)。
◆本文的添彩点：
①恰当运用以下词组和句式：
As
is
known
to
us...正如大家所知……；
would
rather...than...宁可……而不……；
over
and
over
again一次又一次；
...books
are
easy
to
carry
and
need
no
electricity，which
means
we
can
read
them
almost
anywhere.……书携带起来容易并且不需要电，这就意味着我们几乎在哪里都可以读书。
The
more
we
read，the
more
we
get.读得越多，收获得越多。
②被动语态的使用：Besides,
books
can
be
kept
for
a
long
time.除此之外，书可以保存很长时间。
【点睛】
书面表达题既不是汉译英，也不是可任意发挥的作文。它要求将所规定的材料内容经整理后展开思维，考查运用所学英语知识准确表达意思的能力。所以，考生不能遗漏要点，要尽量使用自己熟悉的单词、短语和句式，尽可能使用高级词汇和较复杂的句式结构以便得到较高的分数。
