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 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 tho people started ttling down to become farmers, and their languages too became more ttled and fewer in number. In recent centers, trade,industrialization沿渡河镇. the development of the nation-state and the spread of universal compulsory education. Especially glbalisation and better communications in the past few decades,all have caud many Languages to disappear,and dominant languages such as English．Spanish and Chine are increasingly taking over.
At prent, the world has about 6 800 languages. The distribution of the languages is h
ugely 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 clo 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 the ems to have much chance of survival.

Teens and younger children are reading a lot less for fun, according to a Common Sen Media report published Monday.
While the decline over the past decade is steep for teen readers, some data in the report shows that reading remains a big part of many children’s lives, and indicates how parents might help encourage more reading.
According to the report’s key findings, “the proportion (比例) who say they ‘hardly ever’ read for fun has gone from 8 percent of 13-year-olds and 9 percent of 17-year-olds in 1984 to 22 percent and 27 percent respectively today.”
