听力原文: As President Bush prepares to address the nation Wednesday evening on a revamped strategy for the Iraq War, Democrats who now control Congress are considering using the power of the purse to prevent to increase U. S. troop levels.
President Bush is expected to call for thousands more U. S. forces in Iraq. Blocking funds could avert such an escalation and Illinois Democratic Senator Barrack Obama says there may be a way to do that.
"My office is now investigating what tools are available to us, to condition or constrain appropriations, but what I've also said is that I'm not willing to create a situation in which troops already in Iraq might be short changed in some way."
But South Carolina Republican Senator Lindsay Graham warned against any attempt to cut off war funding. "I think it would be a monumental mistake that we will pay for decades." Still many other GDP lawmakers have expressed doubts about raising the force level in Iraq.
What could be a way to prevent Bush from increasing the U. S. troop levels in Iraq?
A.Calling for people's protest.
B.Blocking war funds.
C.Constraining president's rights.
D.Investigating into the escalation.
