Question

    When we think about the deserts of the world, water abundance(资源丰富)is one of the last things that come to mind. But that might change for the Taklamakan Desert (塔克拉玛干沙漠) in China.

There is a huge underground sea that has more water than all of the great lakes in total in North America. "People have never dared to imagine so much water under the sand before, "said Professor Li Yan.

A basin is, a valley (山谷）that usually collects water from the mountain drainage systems(山脉排水系统), like water that has melted and is running down from nearby, snow-covered mountains. But, if you look at the Tarim (塔里木)basin, you won't see any water.

That's partly because local people collect most of the melt water to irrigate crops. The rest either seeps into the ground or evaporates into the dry desert air.

So how did this desert have such huge water? It dates back to (追溯到)2,000 years ago when farmers in the region began irrigating the land. And the soil of the local farmlands is salty, like the sea. "As a result, agricultural development over human history has enhanced the carbon sink," they write in their report.

They estimate(估计)that as much as 10 times the amount in all of the great lakes could be down there. The scientists don't advise locals to go digging for it, though, because it's extremely salty sea water.

4.Why do the scientists advise locals not to dig for the water?

A.Because it's a dirty sea. B.Because it's salty.

【解析】

文章介绍了塔克拉玛干沙漠地下有非常充足的水源，以及介绍这些水是如何形成的。

1.

细节理解题。根据文中When we think about the deserts of the world, water abundance(资源丰富)is one of the last things that come to mind. But that might change for the Taklamakan Desert (塔克拉玛干沙漠) in China.可知，文章讲述的是中国的塔克拉玛干沙漠地下的水资源的问题，所以这个故事是发生在中国，故选A。

2.

细节理解题。根据文中There is a huge underground sea that has more water than all of the great lakes in total in North America. “People have never dared to imagine so much water under the sand before,” said Professor Li Yan.以及So how did this desert have such huge water?可知，他们发现了塔克拉玛干沙漠有水，故选C。

3.

词义猜测题。根据文中A basin is, a valley (山谷）that usually collects water from the mountain drainage systems like water that has melted and is running down from nearby, snow-covered mountains.……是一个山谷，通常从山区排水系统收集水，就像融化的水从附近积雪的山上流下来一样。由此可知，这里的basin指的是“盆地”，故选A。

4.

细节理解题。根据文中The scientists don’t advise locals to go digging for it, though, because it’s extremely salty sea water.可知，因为水太咸了，所以科学家不建议人们挖，故选B。

5.

主旨大意题。根据文中When we think about the deserts of the world, water abundance(资源丰富)is one of the last things that come to mind. But that might change for the Taklamakan Desert (塔克拉玛干沙漠) in China.以及后文的描述可知，文章主要是介绍塔克拉玛干沙漠地下有水的问题，所以D选项比较符合，故选D。
