听力原文： North Korea on Sunday accused the United States of plotting an atomic attack against it, continuing the North's rhetoric over its moves to develop nuclear programs. Chief U. N. nuclear inspector Mohamed E1Baradei said in an interview that all countries must be treated equally. When asked whether North Korea poses a greater threat than Iraq, ElBaradei said that in both cases, we are worried about the proliferation of nuclear weapons. "The difference is that, in Iraq, we can now check with a team of highly qualified inspectors whether there is a new nuclear weapons program," said E1Baradei, who heads the International Atomic Energy Agency. The nuclear dispute flared in October when Washington said Pyongyang admitted pursuing a nuclear program.
