人们经常用“居然不知道美国有华盛顿，法国有个拿破仑”来形容不懂历史的人，可见这两个英雄人物在历史上具有重要的作用。但这两个人的历史命运运迥然不同，一个是广受褒奖，一个却毁誉参半，这究竟是为什么？让我们走进英雄的时代，一起去感触英雄与时代共同跳动的脉搏。
（1）华盛顿在担任大陆军总司令时，美国如刚出生的婴儿却与摩天巨人进行战斗。说“美国是刚出生的婴儿”是指历史上什么事件？
（2）华盛顿功成身退，“挥一挥手，不带走一片云彩”。化的一段告别词让全国为之感动。请你说出华盛顿的两个主要功绩。
（3）拿破仑经40余胜战，但他却对此不以为然，而对一样东西情有独钟。这个东西是什么？ 为什么让英雄对它如此留恋？
（4）华盛顿、拿破仑作为资产阶级政治家对人类历史的共同作用是什么？

根据材料内容，选择正确答案。

    One of my favourite things to do is hiking in mountains. Because nobody likes the idea of getting lost, I always prepare before every trip. But what's the best navigation tool, a Global Positioning System (GPS) or a good old map and compass? Five of my friends and I hiked through the mountains on a trail I marked. One team of three carried a GPS, and the other team used a map and compass.

    It took the GPS team 3 hours and 11 minutes to get through the whole hike, however, it took the map and compass team only 2 hours and 49 minutes. The biggest problem the GPS team met was that they lost the satellite signal (卫星信号) in some places. With no map or compass, they had to walk around until they were in a place where the signal was good. The map and compass team was able to spot(认出) different landmarks, compare them to their maps and then use the compass to point them in the right direction.

    When I head out on my future hikes, I'm bringing a map, a compass and a GPS to show me the way.

    "Everything happens for the best." my mother said whenever things weren't going my way. "Don't worry. One day your luck will change."

    I found mom was right after I finished my college education. I had decided to try for a job in a radio station. I wanted to host a sports program one day. I went to Chicago and knocked at the door of every station. But I got turned down every time.

    In one station, a kind lady said my problem was that I hadn't got enough experience." Get some work in a small station and work your way up," she said.

    I went back home. I couldn't get a job there, either. I felt really down. "Your luck will change," Mom said to me. I tried another radio station in Iowa. But the owner told me he had already had someone. As I left his office, I asked, "How can someone be a sports announcer (播音员) if he can't get a job in a radio station?"

    I was waiting for the lift when I heard the man call. "What did you mean? Do you know anything about football?" He put me in front of a microphone and asked me to try to imagine that I was giving my opinion on a football game, I succeeded.

    On my way home, Mom's words came back to me," One day your luck will change, Son. And when it happens, you'll feel doubly good because of all the hard work you've had." At that moment I knew just what she meant.
