so that引导结果状语从句和目的状语从句有什么区别

Question

如题所述

Answer 1

so
that可以用来引导目的状语从句，相当于in
order
that,
目的状语从句里常用情态动词may,
can,
might或could表示目的。如：
i
shall
write
down
your
name
so
that
i
can
keep
in
touch
with
you
later
on.
they
climbed
higher
so
that
they
might
get
a
better
view.
上两句中的so
that都可以替换成in
order
that。在现代英语中，这样使用时，so
that中的so还可以省略，以上面的第二句为例，可以改写为：
they
climbed
higher
in
order
that
they
might
get
a
better
view.
they
climbed
higher
that
they
might
get
a
better
view.
so
that也可以用来引导结果状语从句。虽有似曾相识的感觉，不能把目的状语从句和结果状语从句混淆。比较下面两个句子的意义和结构，就很容易区别了。
he
spoke
at
the
top
of
his
voice
so
that
the
students
at
the
back
could
hear
him.
他说话声音很高，为的是后面的同学能听见。(目的状语从句）
he
spoke
at
the
top
of
his
voice,
so
that
the
students
at
the
back
heard
him.
他说话声音很高，结果后面的同学都听见了。(结果状语从句)
so
that引导的结果状语从句一般要用逗号和主句隔开，从句里没有表目的的情态动词may,
can,
might或could。
总之，无论so
that引导目的状语从句，还是引导结果状语从句，都通常位于句中，而不置于句首。
