3．How many languages are spoken by less than 6,000 people at present?

A．About 6,800.　 B．About 3,400.

C．About 2,400. D．About 1,200.

【答案】　B　数字计算题。

根据第三段中的"At present，the world has about 6,800 languages."可知，目前世界上有大约6 800种语言；再根据"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，目前世界上一半的语言的使用人数少于6 000，也就是说有大约3 400种语言的使用人数少于6 000。

4．What is the main idea of the text?

A．New languages will be created.

B．People's lifestyles are reflected in languages.

C．Human development results in fewer languages.

D．Geography determines language evolution.

【答案】　C　主旨大意题。

文章介绍了语言的种类随着人类社会的发展而逐渐减少这一现象，故C项概括全面。

A项颠倒是非，文章介绍的是语言的减少而不是新语言的创造。B、D两项无中生有，文中没有提到人们的生活方式会反映到语言上，也没有提到地理决定语言的发展。
