问题 综合

读下面甲、乙两国图,回答问题。

(1)分析甲国和乙国的气温年较差和日较差不同的主要原因。(10分)

(2)M与N 两河的水文特征差异较多,在众多差异中请选择一个,试从气候成因的角度分析此差异产生的原因。(10分)

答案

(1)甲国气温年较差和日较差大于乙国(2分)。甲国位于亚欧大陆内部,远离海洋,大陆性强;夏季气温高与乙国,冬季气温低于乙国,所以气温年较差大于乙国。(4分)甲国属于温带大陆性气候,降水少,晴天多;白天,大气对太阳辐射削弱作用小,气温高;夜晚,大气对地面的保温作用小,气温低,所以甲国气温日较差大于乙国。(4分)

(2)径流量:M河流域深居内陆降水少,对河流补给少。(5分)N 河流域终年受来自海洋西风控制,降水多,对河流补给多。(5分)

流量季节变化:M河水位季节变化大,夏季河流补给水源不来自降水,而是冰雪融水。(5分)  N 河水位季节变化小,流域终年受来自海洋西风控制,降水分配均匀,对河流补给稳定。(5分)

结冰期:M河流域有冰期,深居内陆,冬季风影响大,气温低。(5分)  N 河流域无冰期,流域终年受来自低纬度海洋西风控制,气温高。(5分)(北大西洋暖流流经沿岸,气温高)

题目分析:

(1)甲国位于亚欧大陆内部,远离海洋,大陆性强;温带大陆性气候,降水少,晴天多;乙国属于温带海洋气候,降水多,阴雨天多。降水量和天气状况是造成年较差和日较差差异的主要原因。

(2)河流的水文特征与流域的地形、气候等关系密切。甲乙两国都是温带的气候类型,但是一个是海洋性气候,降水多,全年温和;一个是大陆性气候,降水少,夏季炎热,冬季寒冷。

Hi, my name is Wang Jun. Do you want to know about my staying in America? Well, to tell you the truth, it is really an eye-opening experience here.

In China, I had English classes five times a week since Grade Five. But I didn’t know textbook English could be so different from everyday English until I came to Hotchkiss School, Connecticut. When I first studied English, I was told to say “I’m fine.” when people say “How are you?” But in the USA, I found that people say “I’m good.” or “I’m tired.”

One day, someone greeted (问候) me with “What’s up?” It made me confused. I thought for a moment and then smiled because I didn’t know what to say.

Since then, I have learnt more and more differences between Chinese and American cultures. To my surprise, American girls spend a lot of time in the burning sun getting a tan (晒黑的肤色). In China, girls try every possible way to keep their skin white.

American students are hard-working like Chinese students. In China, schoolwork is almost everything, so we study hard and that’s it. But here, a “good” student not only gets good grades, but also does a lot for the public. That is to say, they get lots of knowledge at school and learn many life skills from social (社会的) work.
