荒漠成因多样,分布规律有异,下列荒漠与其对应的地域分异规律正确的有(  )

A.撒哈拉沙漠——赤道向两极的地域分异规律

B.塔克拉玛干沙漠——从沿海向内陆的地域分异规律

C.南美南部安第斯山脉以东沙漠——垂直地带分异规律

D.西藏海拔5 000 m以上的荒漠——非地带分异

答案

AB

考察的知识点:自然地理环境的差异性,具体考察荒漠的形成原因。

思路分析:解决本题首先必须知道荒漠的形成原因有哪些,然后根据选项逐一分析排除。

具体解答过程:撒哈拉沙漠形成原因是信风带和副热带高气压带控制形成,风带和气压带是由于不同纬度地区所得到的太阳辐射有差异而形成,是以热量为基础的,因而属于赤道向两极的地域分异规律,答案A正确。塔克拉玛干沙漠形成是由于深处内陆,远离海洋,受海洋的影响小,降水少而形成的温带大陆性气候下发育的温带荒漠景观,是海陆位置原因所形成的,因而属于从沿海向内陆的地域分异规律,答案B正确。南美南部安第斯山脉以东沙漠是由于该地区处于安第斯山脉的背风坡降水少而形成,因而属于非地带分异,答案C错误。西藏海拔5 000 m以上的荒漠形成属于垂直地带分异规律,答案D错误。

Strange things have been happening to England. Still (1) from the dissolution of the empire in the years (2) World War Ⅱ, now the English find they are not even British. As the cherished "United Kingdom" breaks into its (3) parts, Scots are clearly (4) and the Welsh, Welsh. But who exactly are the English What’s left of them, with everything but the (5) half of their island taken away

Going back in time to (6) roots doesn’t help. First came the Celts, then the Romans, then Angles, Saxons, Jutes, Danes. Invasion after invasion, until the Norman Conquest. English national identity only seemed to find its (7) later, on the shifting sands of expansionism, from Elizabethan times onwards. The empire seemed to seal it. But now there’s just England, (8) of a green island in the northern seas, lashed by rain, scarred by two (9) of vicious industrialization fallen (10) dereliction, ruined, as D.H. Lawrence thought, by "the tragedy of ugliness," its abominable architecture.

Of all English institutions, the one to (11) on would surely be the pub. Shelter to Chaucer’s pilgrims, home to Falstaff and Hal, throne of felicity to Dr. Johnson, the pub- that smoky, yeasty den of jollity-is the womb of (12) , if anywhere is. Yet in the midst of this national (13) crisis, the pub, the mainstay of English life, a staff driven (14) into the sump of history, (15) as the Saxons, is suddenly dying and evolving at (16) rates. Closing at something like a rate of more than three a day, pubs have become (17) enough that for the first time since the Domesday Book, more than half the villages in England no longer have one. It’s a rare pub that still (18) , or even limps on, by being what it was (19) to be: a drinking establishment. The old (20) of a pub as a place for a "session," a lengthy, restful, increasingly tipsy evening of swigging, is all but defunct.
