自20世纪60年代以来,巴西致力于亚马孙平原热带雨林的开发。由于开发不当,产生了“修路采矿开牧场,烧荒种地砍树忙”的乱象。据此回答小题。

小题1:巴西肆意开发亚马孙热带雨林,致使全球生态环境受到严重威胁,这是因为开发亚马孙热带雨林造成:

①水土流失严重   ②土地荒漠化严重

③影响全球气候   ④珍贵的野生动物遭劫

A.①②③

B.①③④

C.②③④

D.①②④小题2:巴西在开发的亚马孙平原上不断地扩大甘蔗的种植,以满足酒精生产的需要,而生产的酒精又极大地支持了另一个行业的发展。这个行业是

A.采矿行业

B.水电行业

C.汽车行业

D.纺织行业

答案

小题1:B

小题2:C

题目分析:

小题1:砍伐亚马孙热带雨林,导致植被覆盖率降低,引起的生态问题有水土流失加重,影响全球的气候,减少生物的多样性。土地荒漠化主要为干旱、半干旱地区土地不合理利用导致的。所以本题选择B选项①③④。

小题2:巴西扩大甘蔗的种植,目的是生产酒精,酒精作为燃料,一定程度上缓解了能源消费紧张的状况,从而促进了汽车行业的发展。

点评:经济发展应该与资源、环境相协调。亚马孙雨林北称为地球之肺,不合理的开发利用将导致严重的生态问题。
