    Dollar bills in the US are about to see some changes. For about 90 years, US money has looked nearly the same.The bills have past US presidents or important men on them, but great women and African-Americans have not been shown.

But that's all going to change very soon. Harriet Tubman will take past President Andrew Jackson's place on the $20 bill. The change will be made to the bill by the year 2020.

Harriet Tubman was an African-American woman who got away from slavery (奴隶制). Later, she became a great leader, who fought for the freedom of slaves.She did something really important in the Underground Railroad, a road that led slaves to freedom in the North.

According to New York Daily News, the back of the $10 bill will have a change, too. Many women fought for their right to vote(选举)in the history.They will be pictured on the back of the $10 bill. The back of the $ 5 bill will include famous people like Martin Luther King Jr.and First Lady Eleanor Roosevelt, who fought for human rights.

All the changes will be shown by the 2020, but it may take a few years for the bills to get into circulation(流通).However,this is a change that will help Americans remember great people who shaped the US.
