3 We may say that anyone who speaks English belongs to the English speech community.For convenience(方便),we may divide the speakers into two groups: one in which the speakers use English as their native language, the other in which the speakers 1earn English as a second language for the purpose of education,commerce,and so on.
4 Learning a second language extends one’s vision and expands the mind.The history and literature of a second language record the real and fictional(虚构的)lives of people and their culture;a knowledge of them adds to our ability to understand and to feel as they feel.Learning English as a second language provides another means of communication through which the window of the entire English speech community becomes a part of our heritage.
