听力原文： President George Bush says he wants to shift the debate about global warming away from cutting greenhouse gas emissions, the focus of the Kyoto Protocol, and towards development of new technologies that would clean up those emissions. In an interview for British commercial television, ahead of the group of eight summit in Scotland this week, Mr. Bush appeared to rule out any suggestion that there could be agreement on legally binding emission cuts. But John Niken, a republican senator, said the US should do more to tackle climate change. 'I certainly don't expect the President immediately to back off this position. But I think there are certain measures that could be implemented which would be progressive in seeking the goal. The President recognizes the climate change is an issue, the real problem is whether the administration is willing to enact very meaningful and important steps in order to address the issue.' Where is the group of eight summit to be held this week?
