问题 综合

甲、乙两国历史渊源悠久,阅读下图并结合所学知识回答问题(19分)

(1)简析甲国A地区沙漠广布成因 (3分)

(2)①、②两城市分别为甲、乙两国的首都,对比分析其不同的区位条件。 (6分)

(3)乙国B平原水灾频繁。从地形、气候、水文等多方面分析当地洪涝灾害频繁的原因(4分)

(4)对比分析流经城市②的河流与锡尔河的水文特征的差异(6分)

答案

(1)位于南亚内陆地区,西南季风难以到达,故干燥少雨(1分)。另外,历史上原始森林遭到破坏,也加重干燥程度(1分);冬季受副高控制(1分)

(2)①城市位于高原地区(1分),气候凉爽,交通便利(2分);②城市位于河口三角洲(1分),靠近河流,交通便利,地势平坦,雨热同期(2分)等。

(3)位于西南季风的上风地带,降水较多;(1分)地势低平;(1分)多条大江大河交汇下流地带,河流汛期集中夏季,径流量大(2分)等。

(4)恒河(或布拉马普特拉河)流量大;有汛期,汛期出现在6~9月;河流的补给形式以雨水补给与冰川融水为主;无结冰期;锡尔河:流量小;有汛期,汛期出现在7~8月;河流的补给形式以冰川融水为主;有结冰期。(一条河流3分,侧重具有差异的方面)

题目分析:(1)根据图示的经纬度位置和海陆轮廓判断,甲国A地区的沙漠为塔尔沙漠,且成因主要从受西南季风影响小,副高影响和历史时期的植被破坏等方面分析。(2)结合图示信息,可从地理位置、气候、地形、河流和交通等因素分析影响城市的区位条件,注意比较分析。(3)图示乙国的B平原,地势平坦,排水不畅;从气候条件分析,该地区受热带季风气候影响,夏季多暴雨;从水文环境分析,该地区河网纵横,多条河流交汇,且位于孟加拉湾的顶部,夏季受风暴潮和天文大潮的顶托作用。(4)河流水文特征可从河流的流量、流量的季节变化、冰期、含沙量、流速和水能资源等方面分析,注意流经城市②的是恒河,受热岛季风气候影响,且该地区地势平坦;而锡尔河位于中亚,受温带大陆性气候影响。注意比较两者水文条件的差异。

点评:本题难度一般,能根据图示的 经纬度位置和海陆轮廓准确的判断地理位置是解题的关键。并结合区域的地理环境掌握影响城市区位、洪涝灾害和河流水文特征的一般分析思维,注意答题的完整性。

A child’s room is not only a bedroom. You can see computers, mobile phones, televisions, DVD players, Playstation, and other 21st-century toys. Britain’s 8 to 16-year-olds have bedroom possessions(财产) about £ 3,300.

But they don’t just have hi-tech toys(高科技玩具). A child’s room also has expensive clothes, sunglasses, watches, and sports equipment(装备) 40% of children have a room that is a home office, mini cinema, and sports hall 。90% have a TV, and 70% have a DVD player. 60% have a CD player, iPod, or MP3 player. 25% have their own computers.

With so much to do in their bedrooms, it is no surprise(惊奇) that children spend more time there than anywhere else in the house. One girl spends so long on her mobile phone in her room that her parents have to text her to speak to her. Another child goes into his room as soon as he gets home form school and plays on his Playstation until bedtime.
