In just two weeks, we’ll come together, as a nation, to mark the 10th anniversary of the September 11th attacks.  We’ll remember the innocent lives we lost.  We’ll stand with the families who loved them.  We’ll honor the heroic first responders who rushed to the scene and saved so many.  And we’ll pay tribute to our troops and military families, and all those who have served over the past ten years, to keep us safe and strong.

We’ll also recall how the worst terrorist attack in American history brought out the best in the American people.  How Americans lined up to give blood.  How volunteers drove across the country to lend a hand.  How schoolchildren donated their savings¹.  How communities, faith groups and businesses collected food and clothing.

We were united, and the outpouring（流露） of generosity² and compassion³ reminded us that in times of challenge, we Americans move forward together, as one people.

This September 11th, Michelle and I will join the commemorations at Ground Zero, in Shanksville, and at the Pentagon.  But even if you can’t be in New York, Pennsylvania or Virginia, every American can be part of this anniversary.  Once again, 9/11 will be a National Day of Service and Remembrance.  And in the days and weeks ahead, folks across the country—in all 50 states—will come together, in their communities and neighborhoods, to honor the victims of 9/11 and to reaffirm the strength of our nation with acts of service and charity.

In Minneapolis, volunteers will help restore a community center.  In Winston-Salem, North Carolina, they’ll hammer shingles⁵ and lay floors to give families a new home.  In Tallahassee, Florida, they’ll assemble care packages for our troops overseas and their families here at home.  In Orange County, California, they’ll renovate⁶ homes for our veterans.  And once again, Michelle and I look forward to joining a local service project as well.

There are so many ways to get involved, and every American can do something.  To learn more about the opportunities where you live, just go online and visit Serve.gov.  Even the smallest act of service, the simplest act of kindness, is a way to honor those we lost; a way to reclaim⁷ that spirit of unity⁴ that followed 9/11.         

On this 10th anniversary, we still face great challenges as a nation.  We’re emerging from the worst economic crisis in our lifetimes.  We’re taking the fight to al Qaeda, ending the war in Iraq and starting to bring our troops home from Afghanistan.  And we’re working to rebuild the foundation of our national strength here at home.

None of this will be easy.  And it can’t be the work of government alone.  As we saw after 9/11, the strength of America has always been the character and compassion of our people.  So as we mark this solemn anniversary, let’s summon that spirit once more.  And let’s show that the sense of common purpose that we need in America doesn’t have to be a fleeting⁸（飞逝的） moment; it can be a lasting⁹ virtue—not just on one day, but every day.
