Challenges of Superpowers and New Changes in the World
yǐ qián以前 ，měi guó美国shì是shì jiè世界shàng上zuì最qiáng dà强大de的guó jiā国家 。
In the past, the United States was the most powerful country in the world.
sū lián苏联jiě tǐ解体hòu后 ，měi guó美国biàn dé变得gèng更qiáng dà强大 。
After the collapse of the Soviet Union, the United States became even stronger.
dàn shì但是 ，lì shǐ xué jiā历史学家kěn ní dí肯尼迪zǎo jiù早就shuō说guò过 ，měi guó美国de的qiáng dà强大kě néng可能huì会yù dào遇到wèn tí问题 。
However, historian Kennedy said long ago that America's strength might face problems.
tā他rèn wéi认为zhōng guó中国huì会biàn dé变得gèng更qiáng dà强大 ，měi guó美国yě也huì会yǒu有xīn新de的duì shǒu对手 。
He believed China would become stronger, and the United States would have new rivals.
xiàn zài现在 ，zhōng guó中国de的fā zhǎn发展hěn很kuài快 ，měi guó美国de的yǐng xiǎng lì影响力biàn变xiǎo小le了 。
Now, China is developing rapidly, and America's influence has decreased.
měi guó美国hé和bié de别的guó jiā国家de的guān xì关系biàn dé变得bù tài hǎo不太好 ，yǒu xiē有些guó jiā国家bù zài不再tīng听měi guó美国de的huà话 。
The relationship between the United States and other countries has worsened; some countries no longer listen to the United States.
xiàn zài现在 ，shì jiè世界biàn dé变得duō jí huà多极化 ，bù zài不再zhǐ yǒu只有yí gè一个qiáng guó强国 。
Now, the world is becoming multipolar, no longer dominated by a single superpower.
kē jì科技yě也zài在gǎi biàn改变zhàn zhēng战争 ，bǐ rú比如wú rén jī无人机 、wǎng luò网络gōng jī攻击hé和rén gōng zhì néng人工智能 。
Technology is also changing warfare, such as drones, cyber attacks, and artificial intelligence.
xiǎo小guó jiā国家yě也kě yǐ可以yòng用xīn新kē jì科技bǎo hù保护zì jǐ自己 。
Small countries can also use new technology to protect themselves.
suī rán虽然kē jì科技jìn bù进步le了 ，dàn但yǒu xiē有些rén人biàn dé变得gèng更qióng穷 ，shè huì社会wèn tí问题yě也duō多le了 。
Although technology has advanced, some people have become poorer, and social problems have increased.
wèi lái未来de的shì jiè世界guī zé规则huì会gǎi biàn改变 ，wǒ men我们yào要guān xīn关心zhè xiē这些biàn huà变化dài lái带来de的yǐng xiǎng影响 。
The future world order will change, and we need to pay attention to the impact of these changes.
