English and English Community
　　1 There is no doubt that English is a useful language. The people who speak English　today make up the largest speech community in the world with the exception of　speakers of Chinese.

　　2 A speech community is similar to other kinds of communities. The people who make　up the community share a common language. Often they live side by side, as they do in　a neighborhood (街坊), a village, or a city. More often they form a whole country.
　　National boundaries, however, are not always the same as the boundaries of a speech　community. A speech community is any group of people who speak the same language　no matter where they happen to live.

　　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 learn 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.
