American English簡稱AE,British English簡稱BE
Although AE and BE are actually the same language,there are still some differences between them.
They are almost the same with each other in grammar,but share differences in some words.For example,Americans call"秋天"fall,while the Britans call it autumn.
The biggest difference between them may happen in pronounciation.In AE,people tend to prounounce words with their tongues rolled so that it sounds round while BE sounds straight.
The diffences are small,but we must pay enough attention to them.
