about
it

★What

the
World
Wide
Web
The
World
Wide
Web
has
been
the
most
popular
development
of
the
Internet.
The

book
with
millions
of
pages.
These
pages
are
called
homepages.

can
find
information
about
almost
anything
in
the
world
on
these
pages.

you
can
use
the
Internet
instead
of
a
library
to
find
information
for
your
homework.
You
can
also
find
information
about
your
favorite
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
and
an“@”(meaning“at”).
This
is
what
an
address
looks
like:
Emily@star.
net.
Write
a
message,
type
in
the
person’s
e-mail
address,
and
then
send
the
message
across
the
Internet.
People
don’t
need
to
use
stamps,
envelopes(信封)or

to
