7、ralia (one，withaquestionmark)：noneoftheseseemstohavemuchchanceofsurvival.语篇解读本文是一篇说明文。文章介绍了世界上语言的种类随着人类社会的发展而逐渐减少这一现象。1Whatcanweinferaboutlanguagesinhuntergatherertimes?ATheydevelopedveryfast.BTheywerelargeinnumber.CTheyhadsimilarpatterns.DTheywerecloselyconnected.答案B解析推理判断题。根据第一段最后一句可知，一些语言专家认为，一万年

9、社会发展的很多因素导致许多语言消失，而逐渐被如英语、西班牙语、汉语等语言取代，这就暗示出这些语言是“占优势的”，故选C项(powerful强大的，有影响力的)。3Howmanylanguagesarespokenbylessthan6,000peopleatpresent?AAbout6,800.BAbout3,400.CAbout2,400.DAbout1,200.答案B解析数字计算题。根据第三段第一句“Atpresent，theworldhasabout6,800languages.”可知，目前世界上大约有6800种语言；再根据该段最后一句“Themediannumber(中位数) ofs

11、guageevolution.答案C解析主旨大意题。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，故选C项。Notes,.高频词汇1.populate vt.居住于；构成人口pulsory adj.义务的；强制的3.globalisation n.全球化；全球性4.distribution n.分布；分配5.uneven adj.不均匀的；不平坦的；参差不齐的.长难句分析The general rule is that mild zones have relatively few languages，often spoken by many people，while hot，wet
12、 zones have lots，often spoken by small numbers.分析：这是一个由that 引导的表语从句。while 连接两个并列分句，hot，wet zones have lots，often spoken by small numbers其实是一个省略句，完整的句子应该是hot，wet zones have lots of languages，and they are often spoken by small numbers of people。翻译：一般规律就是温带地区语言种类较少，但说这些语言的人数较多；而热带，潮湿的地区语言种类较多，但说这些语言的人数较少。- 4 -
