参考答案B
解析:Good moming everyone. Today I'm going to talk about some large language families. I'll begin my talk with two questions. Do you know how many languages are used throughout the world today? How many major language families are there? OK, I'll give you a brief introduction about the language families. 
Even though there are over 3,000 languages that are used today. There are only
about 20 to 30 major language families. Let's take a brief look at some of the largest language families. Each of these large families includes many individual languages.
The language that we are using now is English. Aw everybody knows. English has become a world language because of its establishment as a mother tongue out- side England. It's spoken by 320 million people. English is a member of the Indo European language family. This large language family includes most of the lan- guages that are spoken throughout Europe, languages such as English, French and Greek. Of course, nowadays many Indo European languages are spoken in other parts of the world. For instance, Spanish, which is an Indo European language, is spoken throughout South and Central America. But originally it was spoken only in Europe.
Another language family is the Afro Asiatic family. I'll spell it, A-F-R-O, A-S- I-A-T-I-C. The Afro-Asiatic family includes most languages in the area of North Africa. Languages such as Arabic, which is spoken throughout the Middle East and many of the local languages of the Sahara Desert region such as Hausa are members of the same family.
In the past few hundred years, there has been a great deal of change in Africa, and outside languages, such as French, are now spoken m some areas of central Af- rica and southern Africa.
A fourth large group of languages is the Sino-Tibetan Family. Sino-Tibetan in- cludes all dialects of Chinese, which is perhaps the most widely used language in the world. There are nearly 800 million speakers of Chinese dialers. Sino-Tibetan also includes the languages of Southeast Asia, languages such as Vietnamese and
