观察下边漫画，回答下列问题：

1946年，美国和苏联两国外交官向各自政府提交了研究报告，对政府的外交政策以及两国间的“冷战”产生了影响。阅读下列材料：

材料一  美国驻苏大使馆代办凯南向美国政府提交了8000字的“长电报”。电文中认为，克里姆林宫对世界事务的认知根源于苏联传统的不安全感。为了求得安全，他们从未考虑与对手达成妥协，而是要将对手置于死地。凯南还将苏联描绘为一个专制传统早已与意识形态强制相整合的国家，因而它认为外部世界是敌对的。美国必须把对付苏联放在美国对外政策的首位。

材料二  苏联驻美大使诺维科夫写了一篇名为《战后美国的外交政策》的报告。报告认为，战后美国争霸世界的动因是垄断资本的帝国主义扩张。美国利用第二次世界大战其竞争对手被削弱的时机，其资本已渗透到世界的许多国家，加强了在世界的经济地位。美国正在从国外和国内两个方向，集中反动力量对苏联进行包围。美国已成为苏联的对手。美国正运用着资本和军事这两种武器妄图达到其称霸世界的目的。

A Father and a Son

    Passing through the Atlanta airport one morning, I caught one of those shuttles that take travelers from the main terminals (航站楼) to their boarding gates. Not many people consider them fun, but on this Saturday I heard laughter. At the front of the first shuttle were a man and his son.

    We had just stopped to let off passengers, and the doors were closing again. “Here we go! Hold on to me tight!” the father said. The boy, about five years old, made sounds of happiness.

    “Look out there!” the father said to his son. “See that pilot? I bet he's walking to his plane.” The son turned his neck to look forward.

    As I was early for my flight, I decided to go back to the terminal. Where I went back again, I saw that the man and his son had returned too. I realized then that they hadn't been heading for a flight, but had just been riding the shuttle.

    “I want to ride some more!”

    “More?” the father said, mock-angry but clearly pleased. “ You are not tired?”

    “This is fun!” his son said.

    “All right.” the father replied, when a door opened, we all got on.

    There are parents who can afford to send their children to Europe or Disneyland, and there are parents who live in million-dollar houses and give their children cars and swimming pools, yet something goes wrong.

    “Where are all those people going, Daddy?” the son asked.

    “All over the world,” came the reply.

    The other people in the airport were leaving for far destinations (终点) or arriving at the ends of their journeys. The father and son, though, were just riding this shuttle together, making it exciting, enjoying being together.

    So many troubles in this country. So many questions about what to do. Here was a father who cared about spending the day with his son and who had come up with this plan on a Saturday morning.

    The answer is so simple: parents who care enough to spend time, and to pay attention and to try their best. It doesn't cost a cent, yet it is the most valuable thing in the world.

    The shuttle picked up speed, and the father pointed something out, and the boy laughed again.
