材料一 斑头雁是食草性水禽,喜集群,飞翔能力强,有迁徙习性,其迁徙路线和时间相对固定,下左图为斑头雁在亚洲地区的主要迁徙路线示意图、

材料二 斑头雁于3月中下旬到达青海湖开始营巢、产卵,6月中旬至7月中旬进入孵化高峰期,然后育雏、换羽,8月底开始迁出。下右图为斑头雁从繁殖地迁至越冬地的实际观测路线及沿线停留地示意图,下表是青海湖附近某地多年平均气象观测资料。

(l)青海湖斑头雁繁育过程与当地气温变化的关系是   。(3分)

(2)斑头雁从青海湖到雅鲁藏布江一带迁徙过程的时空特点是   ,沿途停留地的环境是   ,(4分)

(3)南亚地区是斑头雁重要的越冬地,其冬季温暖的原因是   。恒河河口湿地和印度河湿地的气候类型分别是      。(4分)

(4)从繁殖地迁往南亚越冬地的过程中,斑头雁可能面临的最严峻考验是   。(填写字母)(2分)

A.飞越唐古拉山口

B.飞越雅鲁藏布江河谷

C.飞越喜马拉雅山

D.躲避恒河河口风暴潮

答案

(13分)

(1)3月中下旬气温回升,湖面解冻,斑头雁飞回繁殖地;6、7月份气温为一年中最高,有利于孵化;8月底以后气温开始逐渐下降,斑头雁开始南迁

(2)历时长;距离远;多次停留   高(原)寒(冷)湿地(河湖、沼泽等)

(3)纬度低、海拔低;北部山地高原对寒冷气流的阻挡     热带季风气候    热带沙漠气候(热带干旱半干旱气候)

(4)C

题目分析:

(1)结合材料二和表青海湖附近某地多年平均气象观测资料可以得出,每年3月中下旬青海湖附近地区气温回升,湖面解冻,适宜斑头雁飞回繁殖地,开始筑巢,产卵,6、7月份气温为一年中最高时期,有利于雁卵的孵化和幼雏的生长发育,8月底以后气温开始逐渐下降,不再适合斑头雁生存,于是开始向南迁移。

(2)分析右图斑头雁从繁殖地迁至越冬地的实际观测路线及沿线停留地示意图可知,斑头雁从青海湖到雅鲁藏布江一带迁徙过程历经3个月的时间,迁徙距离接近1500km,中间有多次停留,历时长,距离远,多次停留是迁徙过程的突出时空特点,沿途停留地多是青藏高原上的河流、湖泊、沼泽地等高原湿地。

(3)南亚地区纬度低,海拔低,而且北部有喜马拉雅山地和青藏高原高原阻挡了北方南下的寒冷气流,所以冬季气候温暖,形成斑头雁重要的越冬地。恒河河口湿地受冬夏季风交替控制,形成终年高温,分明显旱雨两季的热带季风气候,印度河湿地所属区域中年首付热带高气压带的控制,盛行下沉气流,降水稀少,形成气干旱半干旱的热带沙漠气候。

(4)斑头雁从繁殖地迁往南亚越冬地的过程中,要越过高大的喜马拉雅山脉,喜马拉雅山脉是世界上平均海拔最高的山脉,气候条件恶劣,所以飞越喜马拉雅山成为斑头雁迁徙过程中可能面临的最严峻考验。

Dear Disney,
Last weekend, the four members of my family spent an enjoyable holiday at the Magic Kingdom - Disneyland. And one event made our visit seem truly magical. We got to the front of the line at Space Mountain, only to find out that our little daughter Gloria couldn't take her ice-cream on the ride. We were so excited that we all forgot ice-cream was not allowed on the ride.

Gloria broke into tears and we all had no idea what to do. Then Murphy, one of the staff(员工) members, came over. She bent down and told Gloria that she would hold the ice-cream for her and give it to her when she finished the ride. Gloria said, "Promise?" Then she gave Murphy her ice-cream, and she completely enjoyed the ride.
Sure enough, as we walked out the exit, there was Gloria's new friend with "her" ice-cream. Now you and I both know what happened, because we know that an ice-cream won't last twenty minutes on a summer afternoon in Florida. Murphy knew' what time we would get off the ride; she went to the nearest shop and bought a brand-new ice-cream thirty seconds before we walked out the exit. Gloria said, "Thank you," but I'm sure she thought it was the same ice-cream.
We know that someone tried hard to make our visit special. Thanks so much for going above and beyond!
Your fan,
Carmen Rivera
