问题 综合

(22分)读世界某地区示意图。回答下列问题。

(1)从成因角度简要说明A处河流源头的岩石类型及判断依据。(6分)

(2)说出AB河段与B湖以下河段在开发利用方向上的不同。(8分)

(3)根据图中信息,指出该区域最适宜发展的工业类型,并简要说明发展该类型工业的条件。(8分)

答案

(1)岩石类型:岩浆岩(喷出岩、火山岩) (2分)

判断依据:该地等高线为同心圆,中高周低的锥形(火山)地貌(2分);且山顶有火口湖泊(2分)。

(2)AB河段:开发水能(水电)(2分);发展旅游(2分);

B湖以下河段:发展航运(2分);引水灌溉(2分)。

(3)工业类型:有色冶金(炼铜)工业(2分)

条件:有色金属(铜矿)资源丰富(2分);水资源丰富(2分);河流落差大,水能资源丰富((2分))。

题目分析:。

(1)从图中可以看出该地等高线为同心圆,中间高四周低,应为锥形火山)地貌,且山顶有圆形湖泊,即火山喷发形成的火口湖,所以A处河流源头的岩石类型应该火山喷出的岩浆冷却形成的是岩浆岩,也可以称之为喷出岩和火山岩。

(2)从图中可以看出上游AB河段流经山区,河流落差大,水能资源丰富,而且流经陡崖形成瀑布景观,所以AB河段开发利用方向主要是开发水能,发展水电,还可以利用瀑布等自然景观发展旅游业,B湖以下河段流经的是平原,地势平坦,水流平缓,水量较大周边分布有较大面积的农田,所以B湖以下河段主要发展航运,可以引水灌溉。

(3)从图中可以看到,铜矿资源丰富,靠近河流,水资源丰富,上游河流落差大,水能资源丰富,有充足的动力,可以发展有色冶金即炼铜工业。

Twelve years ago yesterday, my mother gave birth to the most beautiful girl.  31 , we were later given the  32  that this little girl, who was three and a half months old, would only have 14 days on the earth. It’s hard to understand what kind of  33  you have when you find out that you’re  34 something that you don’t even know.

As time went on, the number of days kept growing, which gave us  35 . When the doctors said that we could take her home, that was  36 reality hit. We had no  37 .

I am from a small town with  38 hospitals, but when you don’t have money, you just don’t  have it. My mother tried for days to get the money, but nothing  39 each time. A caseworker(社会工作者) was even doing her best. It’s  40 that it almost felt as if we had to  41  a baby from the hospital.

One day the caseworker walked into her boss’s office to  42  again. As she walked out,  43 down yet again, out of nowhere a man walked up to her. He  44 her a handful of money and said, “Please give this to the lady in  45 , so she can take her daughter home.” She looked down at her hand with tears in her eyes. As she looked back up to thank him, he was  46  . They searched all over that hospital and he was no where to be  47 .

Thanks to the guy that I will  48 know, we could take home that  49 baby girl that was only given 14 days to live, and celebrated her 12th birthday yesterday. I am grateful to this man and feel that his act of  50 should be shared with everyone.
