特殊用法
1.不及物动词无被动语态。

2.有些动词用主动形式表示被动意义。
如：
write,
sell,

pen
writes

3.感官动词或使役动词使用省略to的动词不定式，主动语态中不带“to”，但变为被动语态时，须加上“to”。
例：make
somebody
do
something→somebody+
be
+made
to
do
something
see
somebody
do
something→somebody
+be
+seen

do
something

my
wallet

little

do
heavy
work.→The
little
boy
was
made
to
do
heavy
work
by

4.如果是接双宾语的动词改为被动语态时，直接宾语（物）作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。
He
gave
me
a
book.→A
book
was
given
to
me
by
him.
He
showed
me
a
ticket.→A
ticket
was
shown
to
me
by
him.
My
father
bought
me
a
new
bike.
→A
new
bike
was
bought
for
me
by
my
father.
5.一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。
We
can’t
laugh
at
him.
→He
can’t
be
laughed
at
by
us.
He
listens
to
the
radio
every
day.
→The
radio
is
listened
to
by

day.

nurse

taking
care
of
the
sick
man.
