Computer
Facts
Smaller
and
better
In
the
1940s,
the
first
computers
were
bigger
than
cars.
Now
computers
are
becoming
smaller
and
better.
Some
computers
are
tiny.
You
may
be
unaware
of
them.
There
is
probably
one
inside
your
TV
or
washing
machine.
You
depend
on
computers
more
than
you
realize.
What
can
we
do
with
computers?
We
can
use
computers
to
calculate.
They
can
calculate
at
a
faster
spend
than
we
can
and
almost
never
give
wrong
answers.
We
can
also
type
and
draw
things
with
them.
In
addition,
computers
can
do
important
jobs
like
operating
railways
and
flying
planes
and
spaceships.
Reading
Is
a
computer
cleverer
than
me?
The
answer
is
“No’’.
Your
brain
can
produce
new
ideas
but
computers
cannot.
However,
one
day
computers
may
be
able
to
do
a
better
job
than
human
beings.
For
example,
they
may
be
better
than
doctors
at
doing
their
job.
What
will
happen
to
us
if
computers
can
do
all
our
jobs?
Will
we
have
nothing
to
do?
Computers
may
change
our
lives,
but
will
they
make
them
better?

Ⅳ.阅读理解
Mr
Guo
is
a
teacher
from
Xi'an.
He
asked
his
students
to
hand
in
their
homework
through
a
QR
code(二维码).
“We
spent
an
hour
or
two
in
class
learning
how
to
generate(产生)
the
codes,
and
in
the
end
everything
gets
easier”,
said
Guo.
“When
students
finish
the
homework,
they
keep
it
on
WeChat(微信).Then,
each
student
makes
his
own
QR
code
and
gives
it
to
me.
So
I
can
check
their
work
everywhere
using
my
computer
or
telephone.”
The
QR
codes
can
be
sent
to
Mr
Guo
by
email,
QQ
and
WeChat.
When
Guo
scans(扫描)
his
students’
QR
codes,
their
homework
appears
on
his
phone.
He
finds
that
their
homework
becomes
more
creative(创新的),
with
many
pictures,
music
and
even
videos.
Guo’s
students
like
the
new
way
and
think
it
is
interesting.
“We
are
living
in
the
information
age.
Many
students
like
to
work
with
computers
which
makes
learning
more
fun,”
said
Tingting,
a
student
of
Guo’s.
“The
paper
is
not
easy
to
keep,
but
the
code
is
easy
to
keep
and
share,”
Guo
said.
“It
is
worth
trying
to
use
new
technology
in
education.
Education
itself
is
a
kind
of
creation.
I
don’t
want
my
students
to
fall
behind
the
times.”
However,
some
parents
are
worried.
They
are
afraid
that
their
children
will
spend
too
much
time
on
computers
and
less
time
communicating
with
teachers.
But
in
fact,
it’s
unnecessary.
Students
still
need
to
look
up
information
in
books
and
write
it
down
when
they
do
their
homework.
They
only
use
the
code
when
they
hand
in
their
work,
which
doesn’t
take
them
too
much
time.
Also
for
teachers,
it
allows
them
to
check
the
students’
work
at
any
time.
And
it’s
also
an
easy
way
to
share
homework
with
other
students.
21.
According
to
the
passage,
students
can
keep
their
homework
on
_________.
A.
What
B.
QQ
C.
email
D.
blog(博客)
22.
Guo’s
students
think
the
new
way
is
_________.
A.
strange
B.
boring
C.
interesting
D.
unnecessary
23.
What
does
“It”
in
Paragraph
4
refer
to?
A.
The
paper
is
not
easy
to
keep.
B.
Keeping
and
sharing
the
code
easily.
C.
Trying
to
use
new
technology
in
education.
D.
Education
itself
is
a
kind
of
creation.
24.
Some
parents
are
worried,
because
they
think
their
children
will
_________.
A.
talk
with
teachers
face
to
face
B.
spend
too
much
time
on
computers
or
phones
C.
not
like
the
new
way
of
handing
in
homework
D.
find
the
QR
codes
too
difficult
to
use
25.
What's
the
main
idea
of
the
passage?
A.
Teachers
needn't
check
homework
any
more.
B.
Students
needn't
hand
in
homework
any
more.
C.
Using
QR
codes
makes
checking
homework
easier.
D.
Some
parents
are
worried
about
their
children.
