C
Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers, small, tightly knit(联系) groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12,000 languages between them.
Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries, trade, industrialization, the development of the nation-state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English, Spanish and Chinese are increasingly taking over.
At present, the world has about 6,800 languages. The distribution of these languages is hugely uneven. The general rule is that mild zones have relatively few languages. often spoken by many people while hot, wet zones have lots, often spoken by small numbers. Europe has only around 200 Languages: the Americas about 1,000, Africa 2,400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800. The median number(中位数) of speakers is a mere 6，000, which means that half the worlds languages are spoken by fewer people than that.
Already well over 400 of the total of 6,800 languages are close to extinction(消亡), with only a few elderly speakers left. Pick, at random, Busuu in Cameroon (eight remaining speakers), Chiapaneco in Mexico(150). Lipan Apache in the United States(two or three) or Wadjigu in Australia (one, with a question-mark): none of these seems to have much chance of survival.

答案解析：
28. B. They were large in number.
解析：根据第一段中的"Some language experts believe that 10,000 years ago...they spoke perhaps 12,000 languages between them."可知，在狩猎采集时代，语言种类是相当多的。
29. C. Powerful.
解析：根据第二段中的"dominant languages such as English, Spanish and Chinese are increasingly taking over"可知，这里提到的dominant languages是指那些越来越占据主导地位的语言，因此"powerful"(强大的)是最合适的解释。
30. B. About 3,400
解析：根据第三段中的"The median number of speakers is a mere 6,000, which means that half the world's languages are spoken by fewer people than that."可知，目前大约有3400种语言的说话者人数少于6000人。
31. C. Human development results in fewer languages.
解析：整篇文章讲述了随着时间的推移，由于人类的发展(如农业、工业化、全球化等)，语言的种类在减少。因此，文章的主旨是人类的发展导致了语言的减少。
