關於Past Participle Phrase.

Answer1: John is calling the police, robbed on his way home.
Answer2: Robbed on his way home, John is calling the police.

I beg to differ.
John is calling the police ~ main clause
robbed on his way home ~ participle phrase

在這問題中, Answer 2 是好很多. 原因如下:~

(1) When a participle phrase indicates a cause, it usually precedes the main clause. That shows a sequence of actions i.e. that is the logical order of cause-effect. If the order is reversed, the sentence may be less effective.

(2) In Answer 1, the participle phrase is right after the word “police”. Though you can shift a participle phrase to a different position, don't risk awkwardness or confusion by placing it too far from the noun (John) it modifies. People may think that police was robbed.


We can change the form of a participle to show action that occurred before another action.
Example:
Having forgotten my wallet, I borrowed some money from my friend.

A participle can also be in a passive form.
Example:
Having been warned of the danger, we took a long but safe route.

Perhaps the best answer is:
Answer3:
Having been robbed on his way home, John is calling the police.

[Robbery happened before calling the police.]
That shows the correct sequence of actions.

1 and 2 is ok too but 1 is better
