Thanks Setanta and McTag.
I think lacking of enough context may easily lead things to different direction.
(1) What I want to express is that there is a party who preaches the party is on behalf of advanced productivity, on behalf of the benefit of the most people and on behalf of the direction of the advance of society.
(2) I think things differ in different country. In US, some cities have no net bar, which is a bar offering surfing Internet service, because these cities actually offer this kind of service without charge, while in China it is charged.
(3) Eh, "bungee jumping" is a compound noun, it is very interestingly similar to its interpretation in Chinese; "base jumping" is not a compound noun, but it will become. Surely I think so.
