President Castro has urged the U.S. to end a five decades old economic embargo, saying it's done huge damage to Cuba. The embargo could only be lifted with the approval of Congress, which is controlled by the Republicans. They have traditionally opposed any such a move. 卡斯特罗总统敦促美国结束对其长达50年的经济封锁,并称这已经使古巴遭受了巨大损失.解除经济封锁必须国会批准,国会掌握在共和党人手里.他们历来反对这项决议. ___________________________________________
