三、阅读理解
The Colorado River supplies water to more than 36 million people in the south-western part of the USA and allows cities like Los Angeles to develop. However, it is hard to meet the region's need for water now.
The river once travelled from the Rocky Mountains to the Gulf of California. Now, dams control the river's water for human use. As a result, the delta (三角洲) at the river's mouth becomes dry and poor.
Not long ago, engineers opened the Morelos Dam to free a temporary burst of water. It allowed the river to reach the sea for the first time in 16 years. It also helped the river's delta come alive.
Several man-made lakes form because of the dams. "These lakes are like banks. They provide a place to save up water for not-so-rainy days—like right now," said an engineer named Taylor.
In wetter times, the river usually finished its journey to the sea. In drier times, however, spring floods brought life back to the delta for a short time. Such difference shows that a little water could make the river flow smoothly.
"Just add water and you can get something amazing," said another engineer. "In this way, we show how to manage rivers sustainably (可持续地) for both people and nature. Although a lot of rivers have similar problems, it's possible to restore them. If we can do it in the Colorado River Delta, we can do it almost anywhere."
( C ) 1. What can we learn from the first two paragraphs?
A. The Colorado River can't reach the ocean.
B. The Gulf of California is flooding.
C. The Colorado River Delta is drying.
D. The water in America will run out.
( A ) 2. What does the underlined word "temporary" in paragraph 3 mean?
A. Lasting for a short time.
B. Lasting for a long time.
C. Plenty of.
D. Lasting forever.
( D ) 3. Taylor used the word "banks" in paragraph 4 to show that ______.
A. lakes can bring us a lot of money
B. we can borrow money from banks to protect those lakes
C. rivers are as important as banks in our life
D. lakes store water in the way banks store money
( D ) 4. Scientists got the idea of adding a little water through ______.
A. teamwork
B. studying papers
C. experience they learnt from other countries
D. their study of the difference between wetter and drier times

答案： 【解析】：
这是一道英语阅读理解题，主要考查学生对文章细节的理解和推理能力。题目给出了一个关于科罗拉多河及其三角洲的阅读材料，并附带了四个问题。我们需要根据文章的内容，逐一解答这四个问题。
1. 对于第一个问题，我们需要从文章的前两段中提取关键信息。文章提到科罗拉多河现在难以满足该地区对水的需求，大坝控制了河流的水供人类使用，导致河口三角洲变得干燥贫瘠。因此，我们可以推断出科罗拉多河三角洲正在变干。
2. 第二个问题要求解释第三段中“temporary”一词的含义。根据文章，“temporary”指的是“短暂的，临时的”，与选项A“Lasting for a short time”相符。
3. 第三个问题涉及到第四段中Taylor使用“banks”一词的意图。根据文章，“These lakes are like banks. They provide a place to save up water for not-so-rainy days—like right now,”这句话表明，湖泊像银行一样储存水，以备不时之需。因此，选项D“湖泊像银行一样储存水”是正确的。
4. 第四个问题询问科学家们是如何想到通过加一点水来解决问题的。文章提到，在湿润时期，河流通常能完成其流向大海的旅程；而在干燥时期，春季洪水则短暂地为三角洲带来了生机。这种差异表明，少量的水就可以使河流顺畅流动。因此，科学家们是通过研究湿润和干燥时期的差异得到这个想法的，选项D是正确的。
【答案】：
1. C
2. A
3. D
4. D
