课时作业(十六) Unit 6 Section Ⅰ Starting out & Understanding ideas Ⅰ.阅读理解 A More and more birds are flying to settle in Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of the local government. Covering an area of over 4,000 square kilometers, Qinghai Lake is also the country's biggest salt lake. Located in Qinghai Province of Northwest China, the lake is famous for the two islands at its northwest point—Cormorant Island and Egg Island. The two islands have plenty of floating grass and various fish, offering rich food sources to birds. The islands have become a paradise for different kinds of groups of birds and have been called “Bird Islands”． Each March and April, when ice and snow covering the Qinghai?Tibet Plateau (高原) start to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs. During the months, flocks of birds cover the whole sky over the islands and bird eggs can be found everywhere. Visitors can hear the singing of birds from miles away. These have become a world?famous symbol of the lake. To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake National Natural Reserve at the end of 1997. Meanwhile, the State has pointed out that the Bird Islands and Spring Bay of Qinghai Lake were central reserves. Inspectors and conservators often patrol (巡逻) the lake, enriching local residents' knowledge of related laws and spreading knowledge about animal protection to visitors. They are making great efforts to call on people to love and protect the birds. At the same time, they have built special fences around the island area to prevent wolves, foxes and other carnivorous animals, as well as illegal hunters from breaking up the birds' building nests, laying eggs and breeding (繁殖).
