chnage the word "oh" in the following sentence and still keeping meaning same,
Oh!, i have been in a UK.
You can simply leave it out, but the sentence won't make sense. What is "a UK"? And don't forget to capitalize "I" since you're referring to yourself.
Other exclamations might be - WOW!, Egad!, Gracious!, Heavens!
The British use Blimey and I believe the Aussies use Crikey.
There are bunches of others that are in American slang.
