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(中中位位数数)of speakers is a mere 6,000，which means that half the worlds languages are spoken by fewer people than that.3030How How many many languages languages are are spoken spoken by by less less than than 6,000 people at present?6,000 people at present?AAbout 6,800.BAbout 3,400.CAbout 2,400.DAbout 1,200.答案答案B B解解析析数数字字计计算算题题。根根据据第第三三段段第第一一句句“At“At presentpresent，the the world world has has about about 6,800 6,800 languages.”languages.”可可知知，目目前前世世界界上上大大约约有有6 6 800800种种语语言言；再再根根据据该该段段最最后后一一句句“The“The median median number(number(中中位位数数)of of speakers speakers is is a a mere mere 6,0006,000，which which means means that that half half the the worlds worlds languages languages are are spoken spoken by by fewer fewer people people than than that.”that.”可可知知，目目前前世世界界上上一一半半的的语语言言的的使使用用人人数数少少于于6 0006 000，也就是说有大约，也就是说有大约3 4003 400种语言的使用人数少于种语言的使用人数少于6 0006 000。BostonBoston：HubwayHubwayStationStation：Tremont St.&West St.Tremont St.&West

30 minutes；4 for the third 30 minutes；later 8 for every half an hour.”可知前半个小时算在6美元中，第二个半小时是2美元；第三个半小时是4美元；接下来每半个小时8美元。如果你想骑行3个小时，就是6个半个小时，共计62488836美元。故D正确。(2019(2019湖北武汉第二中学仿真模拟湖北武汉第二中学仿真模拟)A few
