有一次，周恩来 * * 到非洲访问，当飞机快要降落时， * * 一边说“我也该整理一下了”，一边抬起手，五指分开，从前额到脑后梳理起头发来，然后两只手同时从两鬓向后，把头发抚平。他的头发本身又黑又亮，经过梳理，显得更有风采了。整理完头发，周恩来又两手举到眉心，用食指和中指轻轻夹着两道长而浓的眉头，从眉头顺势抹到眉梢，再用手掌轻搓两颊。最后站起身，从上到下，抚平衣服。我们大家都敬重和钦佩敬爱的周 * * ，这不仅是因为他知识丰富，思维敏捷、谈吐机智、彬彬有礼，他的堂堂仪表、翩翩风度也是我们心中仪表美的楷模。1972年2月21日，美国总统尼克松激动而兴奋地走下“空军一号”飞机时，周恩来 * * 正不卑不亢地等待在舷梯旁。他给尼克松留下的第一个深刻的印象就是：周恩来站在舷梯前，在寒风中不戴帽子。请问：
