Hello, teachers.

1.He sometimes do admirable deeds which others don't know about.

In this sentence, "about" can not be omitted, right?

2.He sometimes do admirable deeds, which others don't know (about).

How about sentence2?
Is it need "about"?

Thank you in advance!

He sometimes does (note 3rd person singular form of simple present which adds an -s or -es).

You really need to have about in both examples. However, it is more correct to say:

He sometimes does admirable deeds, about which others do not know.

Hello, KazAV-san.
Thank you for your reply!!

>He sometimes does admirable deeds, about which others do not know.

In this sentence, "admirable deeds" is the antecedent of the relative pronoun clause, is'nt it?

Then if the whole foregoing clause( "He sometimes does admirable deeds" ) is the antecedent , what would the sentence be like?

Others don't know that he sometimes does admirable deeds.
→He sometimes does admirable deeds, which others don't know.

I thought this way. Is it wrong?

With regards,
Junkomama
