例如：As
we
can
see,he
is
a
Chinese.
2.As
還可引導原因狀語從句,“因為,由於”
例如：As
he
is
so
lazy,he
never
cooks
by
himself.
3.As還可引導時間狀語從句,“當,隨著”
例如：As
the
weather
is
colder
and
colder,the
leaves
of
the
tree
is
less
and
less.
4.As還可引導方式狀語從句,“按照”
例如：You
must
do
the
work
as
I
have
told
you.
5.As還可引導讓步狀語從句.“盡管”.但是註意,as引導方式狀語從句時從句必須倒裝.而且這種倒裝和壹般的倒裝不壹樣.as從句的倒裝壹般是把從句的表語或作狀語的副詞提到as之前,（如果表語是壹個帶有不定冠詞a或an的單數名詞,倒裝後a或an必須省略).
例如：Though
he
is
a
little
boy,he
knows
a
lot.如果變成由AS引導,就必須變成：
Little
boy
as
he
is,he
knows
a
lot.
Though
he
works
hard,he
never
succeed.
可變為
Hard
as
he
works,he
never
succeed.
