《创新设计》2022年高中人教版生物必修3练习：第6章 章末过关检测(六) A卷 Word版含答案
章末过关检测(六) A卷学问点一人口增长对生态环境的影响1．全面建设小康社会需要处理好人口增长和环境、资源的关系。
下列与我国人口有关的说法中，不正确的是()。
A．目前我国人口的自然增长率不高B．优生优育是提高我国人口素养的重要措施C．我国人口基数过大，使每年新增人口的规模大D．本世纪中叶，我国人口将达峰值15亿左右，所以我国人口的K值为15亿答案 D解析到本世纪中叶，我国人口将达峰值15亿左右，这是在方案生育政策及诸多因素的把握下达到的最大值，并不是环境容纳量。
2．人口数量增长对自然环境的影响越来越大的主要表现有()。
A．种植农作物、饲养家畜和家禽等B．开发和利用自然资源的程度和范围大为扩展C．人口数量增多，使得生活排污量剧增，必定造成对环境的侵害D．生产规模不断扩大必定导致环境严峻污染答案 B解析种植农作物、饲养家畜和家禽等自农业社会以来就有，并不表明人口数量增长对自然环境的影响越来越大。
人口数量增长对自然环境的影响越来越大，其主要表现为：①人类开发和利用自然资源的程度和范围大为扩展；②生活排污量剧增，往往造成对环境的侵害；③生产规模不断扩大，消灭了大量的生产废弃物，对环境产生影响。
需要留意的是无论生活排污还是生产废弃物，造成对环境的侵害都不是必定的。
3．人口增长对生态环境的压力体现在哪些方面()。
①对土地资源的压力②对水资源的压力③对能源的压力④对森林资源的压力⑤使环境污染加剧A．①②③B．①②④C．①②③④D．①②③④⑤答案 D解析人口增长对生态环境的压力表现在土地资源、水资源、能源、森林资源、环境污染等很多方面。
4．如图表示四个国家的人口诞生率和人口死亡率，其中人口自然增长率最高的国家是()。
A．①B．②C．③D．④答案 C解析从曲线上可以知道，横坐标表示的是人口诞生率，纵坐标表示的是人口死亡率，那么自然增长率应当是两者之差。
据此可以知道，选项C符合题意。
学问点二关注全球性生态环境问题5．为解决粮食和环境问题，可实行的科学、有效、合理的途径是()。

Kids learn language skills best by reading, talking and playing with others. If they spend too much time watching TV, they’ll have less time for those things. It may make it harder for them to get on well with others when they grow up.Watching too much TV is also bad for kid’s health. It’s bad for the eyes. Kids don’t move much while watching TV. What’s more, they may eat a lot of food while watching TV. This can make them fat. We call people who watch too much TV "couch potatoes".Fighting on TV is a big problem for kids.
