阅读理解 New coins are coming out all the time. And did you know that the United States Mint makes some coins to collect rather than spend? One collecting kind is called 'commemorative'-coins that honor famous people, places, and events. If you have coins to spend, those are called 'circulating' coins. 2008 American Bald Eagle Coins celebrated an American success story: the bald eagle (秃头鹰). Congress passed an act to recognize the eagle, its importance as a national symbol,and its return from near extinction (灭绝) in the lower 48 states. The series celebrated the eagle's recovery as well as the 35th anniversary of the Endangered Species Act of 1973, which had helped in the recovery. The Founding Fathers chose the bald eagle as the Great Seal of the United States at the Second Continental Congress in 1782. Ever since, this bird has represented the spirit of freedom and democracy.  The eagle also appears on the seals of many branches and departments of the United States government. The bald eagle is a major symbol of democracy, standing for American values like freedom, courage, and strength. It has appeared in American art, music, history, literature, and culture. So, the bald eagle is very important to the United States. This once?endangered species, unique to North America, is now making a gradual comeback. Classified as 'endangered' in 1973 under the Endangered Species Act, this eagle was later moved to the less endangered 'threatened' list, thanks to the law, caring people and organizations. The bald eagle will probably be removed from the 'threatened species' list, but the eagle won't be 'out of the woods' just yet. Wildlife agencies will need to keep an eye on the eagle for at least 5 years after it's taken off the list. Part of the surcharge (额外费用) on the bald eagle coins can be used to help this work . 1.
