什么样的定语从句可以省略关系代词和be动词

Question

如题所述

Answer 1

如果定语从句的先行词就是指代前面的人或物【即在定语从句中作主语或宾语】，那么很多情况下可以转换成用现在分词词组或过去分词词组作后置定语，取代定语从句。如：
Do
you
know
the
man
who
stood
at
the
gate
just
now.=Do
you
know
the
man
standing
at
the
gate
just
now?
The
bridge
which
was
built
last
year
cost
a
lot
of
money.=The
bridge
built
last
year
cost
a
lot
of
money.
如果定语从句本身是进行时或被动语态，基本上都可省略的。如：
The
old
man
who
is
sitting
under
the
tree
is
his
grandfather.=The
old
man
sitting
under
the
tree
is
his
grandfather.
The
car
which
was
bought
last
year
has
been
stolen.=The
car
bought
last
year
has
been
stolen
.
