the way 表方式、方法时，其后由that ⼀ In which 引导定语从句？关系词也可省略

当way做先行词,并在定语从句中做状语时,关系词用that或in
which或省略
先行词是the
way时，其后的定语从句关系词有三种，例如：
I
like
the
way
in
which
/
(that)
the
teacher
gives
his
lessons.
从句缺少的是主语、宾语还是状语是确定用关系代词还是关系副词的关键。也就是说要看先行词在定语从句中担任什么成分
试比较：
I
will
never
forget
the
day
(which/that)
I
spent
in
Hongkong.
(
spent是及物动词，后缺宾语，因此用关系代词或省略
)
I
will
never
forget
the
day
when/on
which
Hongkong
returned
to
its
motherland.
（
从句主谓宾结构完整，缺状语，因此用关系副词或介词加关系代词
）
