a poor writer. send it back to rewrite.
1 2 3 4 5, you've only written 3 4 5. where are 1 and 2?
1) the us armed forces - from budget, advanced weaponry, neuclear powered vesseles, information/satellite/network... tons of aspects you could write.
2) the us dollar system - how many countries are using us dollar as their sole or primary legal currency, petrodollar, investment/stock market, dominance on world trade...
i could go on and on but i'll leave the rest of it for you to think and write. best of luck.
美国在短短的二百年里，成为世界上的科技强国，经济强国，军事强国，主导全球的秩序，成为世界的经济政治科技中心，可以说是个奇迹。
