Ⅳ.阅读理解
Computers
are
useful
machines.
They
can
help
people
a
lot
in
their
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
computer.
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
cannot
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(被决定)
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

can
live
well
without
computers.
C.

must

forms
of
the
following
adjectives
通过完成练习，了解学生理解掌握情况，以便及时查缺补漏。
Let’s
learnLet
the
Ss
learn
how
to
use
the
comparative
and
superlative
forms
of
the
following
adjectives.形容词、副词比较级的用法1.两者进行比较,表示“一方比另一方更……”①
A
+
be
+
形容词比较级
+
than
+
Be.g.
I’m
more
outgoing
than
you.②A
+
实义动词
+
副词比较级
+
than
+
Be.g.
Tom
jumps
higher
than
Jack.
2.“比较级＋and＋比较级”意为“越来越……”
。多音节比较级用“more
and
more＋形容词原级”形式。e.g.
It’s
getting
worse
and
worse.
The
wind
became
more
and
more
heavily.
3.
“the
+比较级……,
the+比较级”，表示“越……越……”。
e.g.
The
more
money
you
make,
the
more
you
spend.
The
harder
you
work,
the
more
you
get.
The
more,
the
better.
4．“Which
/
Who
is
+
比较级…？”后面含有or的选择疑问句中，
如果有两者供选择，前面的形容词要用比较级形式。
e.g.
Who
is
taller,
Tim
or
Tom?
Which
T-shirt
is
nicer,
this
one
or
that
one?
5.“the+比较级+of
the
two”两个中比较.....的e.g.
This
watch
is
the
cheaper
of
the
two.
He
is
the
better
of
the
two.6.
表示在两者之间相差的程度用“具体数字+比较级+
than+
比较对象”e.g.
The
road
is
two
metres
longer
than
that
one.
This
pencil
is
four
inches
shorter
than
that
one.7.用“比较级+than
any
other+单数”表示最高级的意思e.g.
He
is
taller
than
any
other
student
in
our
class.使用形容词比较级时需注意以下几点：1.
than后面接代词时,
一般要用主格形式，但在口语中也可使用
宾格形式。
e.g.
My
brother
is
taller
than
I/me.
2.
当需要表示一方超过另一方的程度时，可以用much,
a
lot,
a
little,
a
bit,
even,
still等来修饰形容词比较级。注意:
比较级不
能用very,
so,
too,
quite等修饰。e.g.
He
is
much
more
serious
than
Sam.3.
形容词比较级后面往往用连词than连接另一个比较的人或事
物,
但在上下文明确的情况下,
形容词比较级可单独使用。e.g.
My
sister
is
tall,
but
my
aunt
is
taller.4.
进行比较的人和物必须是同一类。e.g.
My
books
are
more
than
yours.
I
have
more
books
than
you.形容词和副词的最高级的用法1.表示三者或三者以上比较,可用“Which/Who
…”+最高级,…,…or
…?”表示.e.g.
Who
is
the
tallest,
Tom
,
Mike
,
or
Jack?2.
最高级+of/among
(同类比较)
in…
(范围比较)e.g.
Tom
is
the
tallest
of
the
three.
Jane
runs
(the)
fastest
in
our
class.3.
序数词修饰最高级e.g.
Mike
is
the
second
tallest
student
in
our
class.4.
one
of
+形容词最高级+名词复数表示“最…
之一”e.g.
Jack
is
one
of
the
tallest
students
in
our
class.5.
当最高级前有物主代词修饰时，其前不加定冠词the.
e.g.
It's
my
best
clothes.
It's
our
largest
machine
in
our
factory.
