【1】有机农业对环境可能产生的影响是 ( )
A. 能源消耗增大 B. 土壤肥力提高 C. 生物种类减少 D. 水体污染加重

A. 劳动力价格低 B. 水热资源充沛 C. 技术力量雄厚 D. 土层深厚肥沃
【答案】
【1】B
【2】A
【解析】
【1】结合材料可知有机农业不使用化学合成的农药、化肥等,因此能源消耗减少、水体污染减轻;结合材料有机农业是一种维持土壤、生态系统和人类健康的生产系统,影响是土壤肥力提高,有利于保护生物多样性,B正确。
【2】我国西部较贫困,劳动力价格低,技术力量薄弱,A正确;我国西部大部分是干旱半干旱地区,降水较少,土壤较贫瘠。
【题目】人口和资源问题能从侧面反映当时社会发展的状况。下表为我国1750-1850年人口和耕地面积相关数据表。读表,完成下列各题。

1750 | 2—2.5 | 0.6 | 0.3-0.24 |
1850 | 4.1 | 0.81 | 0.2 |
【1】这一时期我国耕地面积总数增加了,人均耕地面积却减少了,其主要原因是( )
A. 土地兼并严重 B. 人口剧增 C. 自然灾害频繁 D. 战乱频发
【2】表中人口与耕地之间的变化说明一个国家要持续发展( )
A. 只有不断扩大耕地面积 B. 必须保持安定统一的国内环境
C. 必须处理好人口与自然资源的关系 D. 只有发展人口、增加劳动力
【题目】联合国历年发布的“人类发展程度指标(HDI)”,是以“预期寿命、教育水准和生活质量”三项基础变量按照一定计算方法组成的综合指标,用来衡量各国的发展水平。下表为四个国家2013年的统计资料,阅读分析表格,完成下列各题。
国家 | 人口密度 (人/km2) | HDI | 平均 寿命 | 国民平均 就学年数 | 老年人口 比例(%) |
甲 | 403 | 0.385 | 51.1 | 3.3 | 2.98 |
乙 | 126 | 0.385 | 54.6 | 4.3 | 3.41 |

丁 | 8 | 0.719 | 67.2 | 8.8 | 15.26 |
【1】根据人口增长模式转变过程的四个阶段,最可能已经进入“低增长阶段”的国家是
A. 甲、乙 B. 甲、丁 C. 乙、丙 D. 丙、丁
【2】关于四个国家发展水平的叙述,正确的是
A. 甲国人口数量最多 B. 乙国老年人口数量比甲国多
