Question

如题所述

Answer 1

定语从句遵守“缺什么补什么”的原则，被定语从句修饰的名词、代词称为先行词。先行词在句子中要充当一定的成份，主语、宾语、状语等。如；① A
prosperity
which
/
that
had
never
been
seen
before
appears
in
the
countryside.
农村出现了前所未有的繁荣。（which
/
that在句中作主语）
②The
package
(which
/
that)
you
are
carrying
is
about
to
come
unwrapped.
你拿那个包裹快要散开了。(which
/
that在句中作宾语）
③I
still
remember
the
day
when
I
first
came
to
the
school.
（在定语从句中做时间状语）
