as past participle = involved / affected
The participle modifies the noun or pronoun in these examples and
can be used instead of a participle clause:
- There was a brawl outside the nightclub. Those concerned
were held in custody overnight. / The youths (who were) involved
were held in custody overnight.
- Many have lost their savings. The pensioners concerned
will receive substantial compensation / The pensioners who
are affected by this will receive compensation.
as far as I'm concerned = in my opinion
When you want to express an opinion, you can use this formula as
an alternative to in my view or in my opinion:
- As far as I'm concerned / In my view / In my opinion,
the English football supporters should not be held responsible
for starting the fight.
as far as x is concerned = concerning x
You can use these expressions to introduce the topic that you wish
to talk about or the issue you want to refer back to - i.e. it may
have been raised once already and you, as the current speaker, want
to return to that topic. As far as x is concerned is a bit
less formal than concerning x:
- As far as foreign languages are concerned, I think they
should be taught in primary schools.
- Concerning foreign languages, in my view it is appropriate
to teach them at primary school level.
