初三英语被动语态，

Answer 1

表示“使、让”的动词make,
have等，以及感官动词see,
watch,
observe,
feel,
hear,
listen
to,
look
at等，在主动语态中，接不定式做宾语补足语时，不定式前的
to
要省略，而变为被动语态时，成为主语补足语的不定式，则必须带to。如：
I
saw
him
go
into
the
teachers’office.
→He
was
seen
to
go
into
the
teachers’office.
看见他进入了教师办公室。
(3)
带双宾语的句子变为被动语态时，既可将直接宾语变为被动语态的主语，而在间接宾语前加to
或for留在动词之后；也可将间接宾语变为被动结构的主语，而直接宾语留在动词之后。但一般采用后一种用法。如：
He
gave
me
the
pen
last
year.
→I
was
given
the
pen
last
year.
/
The
pen
was
given
to
me
last
year.
这支笔是去年给我的。
一般说来，间接宾语前带to的动词有：bring,
give,
hand,
lend,
offer,
pass,
post,
send,
show,
take,
teach,
tell,
write,
throw等；间接宾语前带for的动词有：book,
buy,
call,
cook,
do,
get,
make,
save等
