[单项选择]It was said by Sir George Bernard Shaw that "England and America are two countries separated by the same language." My first personal experience of this was when I worked as a camp counselor for two months in 2000 in Summer Camp run by the Boy Scouts of America, as part of an international leader exchange scheme. Before I went, all the participants in the scheme were given a short list of words that are in common use in the UK which Americans would either be confused by or would even offend them. I memorized the words and thought "I’ll cope".
When I finally arrived in the States three months later, I realized that perhaps a lifetime of watching American television was not adequate preparation for appreciating and coping with the differences between American and British speech. In the first hour of arriving at the camp I was exposed to High School American English, Black American English and American English spoken by Joe Public, all every different to each other. Needless to say,
A. England and America used to be one country but were separated by the language.
B. England and America share the same language but the language separates them
C. England and America share the same language but show differences in the language use.
D. British English and American English are almost the same in the two countries.
