Mauritius was a British colony for almost 200 years, excepting for the domains of administration and teaching, the English language was never really spoken on the island.
我来贴一点儿关于except 和 except for的用法。---来自Ron
i do believe that "except for" is considered correct, but it's usually wordy; in mast cases in which it's appropriate, you can just use "except" instead.
ex:
the delegates came from all U.S. states except for Florida.
--> better: the delegates came from all U.S. states except Florida.
in most cases, though, except + preposition is not actually an idiomatic construction at all. what you're seeing is the use of the word "except" - in isolation - followed by a preposition that goes with whatever words follow.
for instance:
gambling is illegal everywhere in the state, except on chippewa reservations.
--> correct. notice that "except + on" is not an idiomatic construction; rather, "on" is simply the pronoun that happens to go correctly with "chippewa reservations."
