就是一个句子在另一个句子中做主语,此时这个句子一定要有一个连接词,以此来区分从句和主句.
连接词分为三类:
1.从属连词
that,whether,if这些词在从句中不充当成分,换句话说,这个从句不缺乏成分
That
the
earth
travels
around
the
son
is
known
to
all.
2.连接代词who,what,which,whatever等,这些词一定要在从句中充当成分,比如,主语,宾语,表语
Who
will
be
in
charge
of
our
class
is
not
decided.(Who在从句中做主语)
3,连接副词where,why
when,how,这些词在从句中做状语
Why
she
was
late
for
school
is
known
to
all.
