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 s. 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 Enered 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 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 , 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?enered species, unique to North America, is now a gradual comeback. Classified as 'enered' in 1973 under the Enered Species Act, this eagle was later moved to the less enered '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.
