sik-hung,
Good point. "in" can mean "at home" as an adverb.
I think "not in" does not necessarily mean 不在家, the sentence could be like this with "in" functioning as a prepositiion:
May I speak to Linda? I'm sorry. She is not in (the office/the job/etc).

" go on a picnic" is the more common phrase which should be used here as: He goes on a picnic in Sai Kung.
"go for" can mean "to go somewhere in order to have". But the sentence is better written as: He goes to Sai Kung for a picnic.

3. 'To keep or retain something' is 'to hold on to or hold back something', not 'hold on something.'
'Hold on' without to means to continue or to stop and wait etc.

For 3, 'To keep or retain something' is 'to hold on to or hold back something', not 'hold on something.'
'Hold on' without to means to continue or to stop and wait etc.
