The

In

come
into

We
live
in
the
“computer
age”.
Computers
are
used
in
many
fields.
They
are
very
important
because
they
can
work
faster
and
make
nearly
no
mistakes.
Computers
can
help
people
do
a

of
work.
Writers
use
them
to
write.
Teachers
use
them
to
help
teaching.
They
are
also
used
for
studying
by
students.
What’s
more,
we
can
use
a
computer
to
search
for
information.
Computers
are
very
useful
and
helpful
in
our
life.
They
have
changed
our
life
and
improved
the
quality
of
people’s
life.
