问题:

美国、俄罗斯(前苏联的主要继承者)是当今世界上具有巨大影响力的两个大国。根据所学内容,完成下列探究任务。

活动主题:走进美俄天地

步骤一:解读材料,走进历史美俄关系一直是世界大国关系中最重要的关系之一。曾经他们一度成为了同仇敌忾的盟者,当把敌人打败后,他们却又变成了势均力敌的仇者,美洲的古巴、亚洲的阿富汗都留下了他们争霸的痕迹。也许在《赫鲁晓夫和肯尼迪的较量》的漫画中,赫鲁晓夫的大汗淋漓就已经暗示了最终的结局,美国如愿以偿成为世界上惟一的超级大国,然而,俄罗斯作为前苏联的主要继承者也是一支不可轻视的力量。军事实力的强大,仍使俄国成为牵制美国的重要力量。

(1)“他们一度成为了同仇敌忾的盟者”是在什么时候?“当把敌人打败后,他们却又变成了势均力敌的仇者”,他们正式成为仇者的标志是什么?
