听力原文:M: British English and American English are really about the same, aren't they? W: I don't think so. It seems that some of the spellings are different. M: You're right, Nina. Words like 'theater' and 'center' end in 'r-e' in England instead of in' e-r' like we spell them. Can you think of any more exampies? W: The word 'color' ? M: Good. Actually, many words which end in 'o-r' in American English are spelled 'o-u-r' 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. But not so different that it prevents us from understanding each other. M: Yes. I quite agree with you. What do both of the speakers agree on?
