SF with a multiplicity of human languages

A relatively common feature in SF is the existance of
a common language. Part of this is, I suspect, the Parking
Problem (1) and perhaps part of it is that a lot of SF writers
are either monolingual or live somewhere where it's quite easy
to get by on one language.

There have to be exceptions, though. Can anyone name some
of the better ones?


1: It's unrealistic that people on TV and movies always find a parking
spot near where they are going but showing them driving around the block
eight times eats up valuable screen time without contributing anything
to the plot.
