听力原文：M: British English and American English are really the same, aren't they? W: I don't think so. It seems that some of the spellings are different. M: You're fight, Nina. Words like 'theater' and 'center, end in 're' in England instead of in 'er' like we spell them. Can you think of any more examples? W: The word 'color' ? M: Good. Actually, many words which end in 'or' in American English are spelled 'our' in British English. W: OK. There are some differences in pronunciation and meaning. M: Anyway, we both agree that British English and American English are different. Right? W: Sure. I quite agree with you. What do both of the speakers agree on?
