解析：青藏高原海拔高，相对同海拔大气层，夏季增温快，形成 热低压，加强南亚夏季风；冬季形成冷高压，加强南亚冬季风。 答案：B

答案C 解题分析 根据上题分析，由于青藏高原的隆起，西北地区降 水减少，植被覆盖率降低，气候的大陆性增强；降水减少，河湖水量 减少，晴朗天气增多，太阳能资源增多。

答案C 解题分析 由于大风日数多，受潭海峡的地形影响，潭海 峡浪高流急，这是有效施工时间短的主要原因；福铁路属于涉水 工程，高温日数和降水日数不是施工环境恶劣的主要原因；潭海 峡位于亚热带季风气候区，无结冰期。

【解析】分析题意可知，丙与丁不存在捕食关系，据此作图。能量流动的特点是单向流动、逐级递减。图中b表示同化的能量值，c表示用于生长、发育和繁殖的能量值，f表示流人下一营养级的能量值，g表示流人分解者的能量值，表示粪便中的能量值。19.(1)化学(1分)有利于保护环境（或杀灭蝗虫的效果比较好）(2分)(2)①甲(1分)食虫鸟的营养级较蝗虫的高，种群数量较少(2分)②（给分要点：曲线中绘出下降和上升的趋势，3分）种群数量时间(3)①各样方距中心点等距且相邻样方间等距(2分)②与对照组相比，施加4-VA的实验组飞蝗数量明显增多(2分)【解析】图1中横坐标代表的是当年的种群数量（八，），纵坐标代表的是一年后的种群数量(N+1),在虚线之下说明种群数量降低，在虚线之上代表种群数量增加。乙的种群数量多于甲，说明甲的营养级高，由此判断曲线甲表示食虫鸟，曲线乙表示蝗虫。在绘制图2甲的种群数量随时间变化的曲线时，注意图1中OA段在虚线之下，种群数量降低，AB段在虚线之上，种群数量增加，BD段在虚线之下，种群数量降低。20.(1)下降(1分)正反馈1分)(2)重金属污染物可通过生物富集最终积累在食物链顶端(2分)就地(1分)(3)①与非养殖区相比，养殖区由浮游植物和海带等构成的生产者可以通过光合作用吸收更多的C()2(2分)食物链（食物网）(1分)利用表层海水C)2形成的碳酸盐构成贝壳(2分)②整体(2分)》【解析】重金属具有生物富集的特点，通过生物富集最终会积累在食物链顶端。与非养殖区相比，养殖区由浮游植物和海带等构成的生产者可以通过光合作用吸收更多的C)2,所以养殖区表层海水C():相对含量较低。贝类可通过利用表层海水C)2形成的碳酸盐构成贝壳来减少海水中的CO2。21.(1)将淀粉分解（进行糖化）(2分)有氧呼吸和无氧呼吸(2分)(2)抑制或阻止其他微生物的生长(2分)(3)0.10(1分)接种量较大，菌数增长过快导致葡萄糖消耗过多，用于酵母菌无氧呼吸产生酒精的葡萄糖减少(3分)(4)酵母菌发酵过程中pH降低和酒精的积累对酵母菌的代谢产生了抑制作用(2分)【解析】图1中加入的甜酒曲含微生物和淀粉酶等，加入甜酒曲的目的除提供少量菌种外，还能促进蒸熟糯米的淀粉分解；主发酵中酵母菌先进行菌体的繁殖，再进行发酵，主发酵中酵母菌的呼吸作用方式为有氧呼吸和无氧呼吸。根据图2中制作黄皮果甜米酒的实验结果可知，YWBY接种量为0.10%时，酒精含量最高，因此，YWBY的最佳接种量是0.10%。【高二生物学·参考答案第3页（共3页）】·24-420B·3
