二、在“全球河流”研究单元，科罗拉多河是一个重要案例。请阅读下面短文，完成以下任务。
The Colorado River is one of the most important rivers in the United States. It's about 2,330 kilometres long. It starts in the central Rocky Mountains of Colorado and flows southwest all the way toward the Gulf of California(加利福尼亚湾) in Mexico.
1. It runs through seven states in the US and provides fresh drinking water for over 40 million people. Farms，factories，and tourism also greatly depend on it. Many dams(大坝) have been built to help save water and generate electricity(发电). Hoover Dam is one of the most important dams along the river.
2. Because of a warming climate，there is much less snow in the mountains and less water runs into the river. The American Southwest has been going through its worst drought(干旱) in years. Though the water in the river has become less，the need for it has even risen. Over the past twenty years，the river has lost about 20 per cent of its flow，and there has been very little water running into Mexico. 3.
Facing such a great challenge，the seven states that depend on the river for water have decided to cut about 25 per cent of their use of water. 4. In fact，since 1922，an agreement called the Colorado River Compact has governed(管理) how the seven states share the water in the river. However，the agreement only works in times of plenty and fails to play a role in times of drought. Now it's very clear that efforts(努力)are far from enough.
Actually，not only the Colorado River，but also many other rivers around the world are in danger of running dry. 5. So it's time for every one of us to step up and do our part to stop rivers from disappearing.
任务一：请根据短文内容从下面方框内的七个选项中选择五个还原到文中，使短文意思通顺、结构完整。一空一句。
A. But it seems to be a difficult job.

E. The river is called “the lifeline for the Southwest” in America.
F. Now scientists say that the river probably won't ever reach the sea again.
G. However，the water in the Colorado River almost gets used up during its journey.
任务二：提升题 请根据短文内容和你的思考回答以下问题。
