奥巴马：美国选民面临世代的抉择
US President Barack Obama has accepted the nomination of the Democratic party, telling voters they face a generational choice in November's election.
美国总统奥巴马接受民主党的候选人提名，他告诉选民们将在十一月的选举中面临着世代的抉择。
He highlighted the differences between his aims and Republican policies, and reprised his 2008 theme of "hope".
"I never said this journey would be easy, and I won't promise that now," Mr Obama told the Democratic convention.
Republican Mitt Romney is challenging Mr Obama for the White House, with polls showing a tight race.
Mr Obama told delegates in the hall and voters watching at home that the nation's problems had built up over decades and could not be fixed in a flash.
"But when you pick up that ballot to vote - you will face the clearest choice of any time in a generation.
"Over the next few years, big decisions will be made in Washington: on jobs and the economy; taxes and deficits; energy and education; war and peace - decisions that will have a huge impact on our lives and our children's lives for decades to come," he said.
Venue change
Mr Obama took the stage not in a huge stadium in downtown Charlotte, North Carolina, as organisers had hoped, but inside the convention centre after Thursday's speech was moved because of weather concerns.
He followed a rousing speech by Vice-President Joe Biden, who praised Mr Obama for his bravery in bailing our the auto industry and ordering the killing of Osama Bin Laden.
The president offered a string of critiques of Republican policies, describing his opponents as "happy to talk about everything they think is wrong with America" without offering suggestions on how to make things right.
"That's because all they have to offer is the same prescription they've had for the last 30 years," he said.
"Have a surplus? Try a tax cut. Deficit too high? Try another. Feel a cold coming on? Take two tax cuts, roll back some regulations, and call us in the morning!"
But there was no mention of his own healthcare law, a signature achievement that remains unpopular with many Americans, and little explicit（明确的） talk of the stimulus enacted in his first months in office.
