V-ing 形式的功能破案
功能一：定语（Attributive）
位置：名词前
作用：描述该名词
功能二：表语（Predicative）
位置：系动词后
作用：补充说明主语
功能三：状语（Adverbial）
位置：句首/句尾
作用：表时间、条件、结果等
Look at the blue words. We can see that V-ing forms can be
used in three different ways!

语法侦探社结案报告:
V-ing 三大功能核心档案
档案一
功能一：定语 (Attributive)
The -ing form of a verb can be
used before a noun to describe it.
例句：
floating cushion, pouring rain
档案二
功能二：表语 (Predicative)
The -ing form of a verb can be
used after a linking verb to provide
more information about the subject
of a sentence.
例句：
is frightening, was damaging
系动词后
名词前
档案三
功能三：状语 (Adverbial)
The -ing form of a verb can be used
to tell time, condition, result, urpose,
etc.
例句:
Listening to…, realising she was…
句首/句尾
We've cracked the case! Let's look at the official grammar rules.

Grammar highlights
深度解密：V-ing 作状语（Adverbial）的四大场景
侦探技巧：V-ing 作状语时，它的逻辑主语必须与主句主语保持一致！
场景一：时间（Time）
Listening to the weather repor，we
prepared…
相当于 When we listened to…
场景二：原因（Reason）
Finally realising she was in danger,
Du ran…
相当于 Because she realised…
场景三：伴随（Accompanying）
People ran for cover,fearing for
their safety…
相当于 …and feared for…
场景四：条件（Condition）
When realising there is a tsunami,
you should…
相当于 If you realise…
状语的四大场景我们已经深度解密了。现在，让我们回到三大功能的整体视角，做最后的结案汇总。
