Adverb clause

[heisazadeh]

Adverbial clauses can be reduced by omitting the subject and the verb to be:

While I was watching TV , I fell asleep.
While watching TV , I fell asleep.

Why this happen?

He was sent to hospital after he was attacked by a man.



He was sent to hospital after being attacked by a man.

Why does the reduced version in bold have the word being inserted?


Thanks in advance

I think it is because you'd use -ing form after prepositions "after" in this case. sorry for repeating the word

As far as the subjet is the same in both sentences I guess you can do it, but what happens when the subject is different?

While he was watching tv, I came in

Simply you can't, because if you did it would sound quite weird. No one would know who was doing such a thing.

Regarding the second example both the subordinate and the principal sentences have the same subject.

I was taken to hospital after he bit me , you can’t say: I was taken to hospital after biting me ?????

Yes, that works if you have the same subject. In passive transformations and in your sentence you could say:
"I was taken to hospital after being bitten by (him)"?? (that's sounds strange ) by a dog, for example.

Try looking at the difference between "while" and "after" as well who is the subject.
