请问下面这段话的主题句是第一句还是最后一句？是用什么段落发展方法展开的？比较法，定义法，举例法，还是归纳法？
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, a village, or a city. More often they form a whole country. Many nations are composed of single major speech community, for example, Italy, Sweden, and Japan. National boundaries, however, are not always the same as the boundaries of a speech community. Some nations (for example, Russia and India) are made up of many speech communities. Some speech communities (for example, Arabic, Spanish, and English) extend across national boundaries. A speech community, then, is any group of people who speak the same language no matter where they happen to live.

文章应该是采用归纳法，中心句是最后一句。文章第一句说了 a speech community也和其他的组织团体一样。接下来作者又说了人们是怎么创建团体的呢？是靠着同一种语言（相识的语言）。接着作者由小及大先从小村庄再到一个国家的形成举例说明。同时作者又说明了现实中的国界有别于语言上的国界。语言可以穿越国界。正如俄罗斯是由个多语种的国家，而某些语言比如英语，西班牙语却穿越了国界，成了很多人的共同语言。所以最后作者得出结论到底什么才是speech community,它取决于说同种语言的人，而不是所居住的地方。
