怎样使用动词不定式的被动语态

Question

如题所述

Answer 1

不定式的逻辑主语通常是句子的主语,如果不定式有自己的逻辑主语,它通常由for或of引起.
动词不定式的一般式表示它与谓语动词同时或之后发生；其完成式则表示发生在谓语动词之前的动作.但要注意动词：plan,
expect,
intend,
wish,
mean,
want,
suppose,
would
(should)like等后面的不定式完成式则表示原打算要做而最终未做成的事情.
当不定式的逻辑主语是动作的承受者时,这个不定式要用被动式,包括它的一般式和完成式
动词make,
let,
hear,
watch,
see,
feel,
help等后面做宾语补足语的不定时一般不带to,如：
The
strange
thing
made
me
feel
thirsty.
这个奇怪的东西是我感到口渴.
I
heard
her
move
about
in
her
room
upstairs
last
night.
昨晚我听到他在楼上房间里走来走去.
Did
you
see
Jack
take
away
the
magazine?
你看到Jack拿走了那本杂志了吗?
当以上所列的谓语动词改为被动语态时,后面的不定式需带to.如：
He
was
heard
to
move
about
in
her
room
upstairs
last
night.
昨晚听到他在她的房间里走来走去.
Was
Jack
seen
to
take
away
the
magazine?
诱人看到
Jack拿走了那本杂志了吗?
（let,
feel和少用于被动语态）

Answer 2

动词不定式有两种被动语态形式：
一般式to
be
done
完成式to
have
been
done
例：
The
next
thing
to
be
done
is
to
carry
away
the
earth.

No
harm
seems
to
have
been
done.
