Tapescript
After
printing
was
invented,
knowledge
was
spread
around
the
world
by
books.
For
many
years,
books
were
very
expensive.
Each
one
was
written
by
hand,
so
very
few
books
were
produced.
Today,
books
are
produced
quickly.
They’re
light,
cheap
and
easy
to
get
hold
of.
But
the
early
books
are
now
too
valuable
to
be
picked
up
and
held
in
the
hand,
so
here
in
the
British
Library,
they
were
copied
onto
a
computer
a
few
years
ago.
Have
a
look
at
the
screen
here.
You
can
turn
the
pages
on
the
screen,
without
touching
the
real
books.

Why
were
so
few
books
produced
in
ancient
times?
2
Why
were
many
old
books
copied
onto
a
computer?
Listen
again
and
answer
the
questions.
Because
they
were
written
by
hand.
They
are
too
valuable
to
be
picked
up
and
held
in
the
hand.

How
has
the
computer
helped
people
read
old
books
in
the
British
Library?
Old
books
were
copied
onto
a
computer
a
few
years
ago
for
people
to
be
able
to
read
them
without
touching
them.

The
history
of
the
Internet
The
World
Wide
Web
The
Internet
and
the
Web
The
future
of
the
Internet
√
The
Internet
has
been
around
for
many
years,
but
it
was
the
invention
of
the
World
Wide
Web
that
made
it
really
useful
to
people.
Together,
the
Internet
and
the
World
Wide
Web
have
changed
the
world.
It
was
that...强调句型
The
Internet
was
invented
by
the
US
government
in
the
1960s,
for
the
army
to
use.
In
the
1970s,
scientists
and
businesspeople
also
wanted
to
use
the
Internet
to
send
and
receive
messages.
For
some
years,
people
could
only
send
very
simple
texts.
They
could
not
send
photos
or
documents
by
the
Internet.
发送和接收信息
That
changed
in
1991,
when
a
British
scientist
named
Tim
Berners-Lee
invented
the
World
Wide
Web.
The
World
Wide
Web
allows
people
to
send
various
types
of
files,
such
as
texts,
photos
and
videos
by
the
Internet,
so
more
and
more
people
started
to
use
it
in
the
1990s.
例如
Today,
the
Web
has
hundreds
of
millions
of
users.
It
has
changed
the
way
people
live,
work
and
play.
Through
the
Internet,
email
allows
us
to
communicate
nearly
instantly
with
people
thousands
of
miles
away.
People
and
businesses
use
e-commerce
and
online
shopping
to
buy
and
sell
things
across
the
world.
数百；成百上千；
许许多多…
The
Web
also
makes
people's
lives
easier
because
now
many
things
can
be
done
from
home,
twenty-four
hours
a
day.
The
Web
can
help
you
do
research
for
your
homework,
so
that
you
do
not
need
to
go
to
the
library.
You
can
use
Internet
banking,
instead
of
going
to
the
bank.
And,
of
course,
people
just
“surf
the
Web”
when
they
want
to
relax.
Technology
changes
quickly,
and
it
is
hard
to
imagine
what
the
future
of
the
Internet
and
the
Web
will
be.
But
it
seems
impossible
to
imagine
life
without
them.
Now
complete
the
chart.

Today
Read
the
passage
and
answer
the
questions.
1.
When
was
the
Internet
invented
by
the
US
government?
2.
What
could
people
only
send
at
first?
In
the
1960s.
They
could
only
send
very
simple
texts.
3.
Who
invented
the
World

Web
in
1991?
4.
Can
people
use
e-commerce
and
online
shopping
to
buy
and
sell
things?
A
British
scientist
named
Tim
Berners-Lee.
Yes,
they
can.
E-books
Just
as
email
has
changed
the
way
we
write
to
each
other,
e-books
are
changing
the
way
we
read.
We
can
easily
download
new
e-books
from
the
Internet.
It
is
much
easier
and
quicker
to
search
for
passages
now,
and
we
can
also
write
notes
in
an
e-book.
What
is
more,
they
save
a
lot
of
paper.

而且，
此外
But
e-book
readers
are
still
more
expensive
than
paper
books,
so
not
all
people
can
afford
them.
However,
with
the
rapid
development
of
electronic
technology,
reading
e-books
will
become
cheaper
and
cheaper.
A
lot
of
people
think
there
will
be
more
e-books
than
paper
books
in
the
near
future.
