(Passive

We
use
the
active
voice
when
it
is
important
to
know
who
performs
the
action.
We
can
also
use
the
passive
voice
when：
1.
It
is
obvious
who
performs
the
action.

processing
skills
are
taught
in
our
computer
lessons.
2.
We
do
not
know
or
do
not
want
to
know
who
performed
the
action.

printer
was
sold
already.

the

is
more

than
the
person
who
performs
the
action.

We

‘by’.
We
put
‘by’

the
name(s)

the

of
a
passive
sentence.

Introduce

enables
us

say
who
