被动语态4
步曲
第1步:被动语态结构
被动语态的时态通过助动词be的变化来表示。经常考查的被动语态结构有:
一般现在时:am
/
is
/
are
+
及物动词的-ed形式
一般过去时:was
/
were
+
及物动词的-ed形式
一般将来时:will
/
shall
+
be
+
及物动词的-ed形式
现在完成时:have
/
has
been
+
及物动词的-ed形式
含情态动词的被动句:情态动词(can
/
should
/
must等)+
be
+
及物动词的-ed形式
第2步:主动句变被动句
☆主动句的宾语变为被动句的主语。当宾语含双宾语时,一般把代表人的宾语(即间接宾语)变为被动句的主语,而把直接宾语留作被动句的宾语。如果把主动句的直接宾语变为被动句的主语,则间接宾语前须加上介词(一般是for或to)。常接to的动词有:give,
tell,
lend,
show,
pass,
hand等;常接for的动词有make,
buy等。
☆主动句的谓语动词变为被动形式,要注意助动词be的时态与主动句的时态保持一致,数与被动句的主语保持一致。
☆主动句的主语变为被动语态中by的宾语(如为代词,主格要变为宾格)。
第3步:被动语态特例展示
特例1
主动句中的谓语是“一感觉(feel)”、“两听(hear,
listen
to)”、“三使(make,
let,
have)”、“四看(see,
watch,
look,
notice)”时,其后作宾语补足语的动词不定式不用to,但变为被动句时,动词不定式符号to要补上。
如:Someone
noticed
Mr
Yu
leave
the
office
at
about
9
am.
→Mr
Yu
was
noticed
to
leave
the
office
at
about
9
am.
特例2
短语动词是一个不可分割的整体,在变为被动句时,不可丢掉构成短语动词的介词或副词,也不能将其拆开。
如:The
workers
put
up
a
tall
teaching
building
in
our
school
last
year.
→A
tall
teaching
building
was
put
up
in
our
school
last
year
