Below are some of the parts in which AI plays a role. AI improves travel experience by making it easy to book flights and hotels and giving the best choice according to travelers’ likes. It can also make a traveling plan by giving advice on activities, dining, and places of interest according to the traveler’s interests. Also, AI shows the weather and so on during trips, to ensure a successful trip. AI has a big influence on home appliances (家用电器), making them more intelligent. Smart fridges can alert when some food is going bad, and even show what dishes people can make according to the available food. AI washing machines and dishwashers make sure their cleaning time matches the size of clothes and how dirty they are, to make the best use of water and energy. And AI ovens can make sure of the cooking times and temperatures, to cook delicious meals. AI has also changed driving a lot as the technology of autonomo us vehicles (无人驾驶汽车) appears. Moreover, AI can help cars talk with each other on the road to ensure road safety. AI can also help improve the traffic conditions by providing real-time traffic information. AI’s role in driving not only helps improve safety but also makes a gr eat difference to traffic. In a word, AI is making our lives easier and safer in certain ways. From making travel easier to smarter home appliances and driving, AI is here to help. We are sure that AI will bring us a lot of wonderful things in the future. ( )1.

London was a busy city with horse-drawn carriages (马车). They often rushed into people, causing many accidents. At the same time, there was a fashion rule in London—women in red showed that they were married and green for unmarried (未婚的). This gave people the idea f or using red and green as traffic signs later. On December 10th, 1868, British mechanic (机械师) De Hart designed the world’s first traffic light with only red and green. A policeman had to pull a belt to change the lights: red meant “stop”, and green meant“ go”. At first, it worked well and reduced accidents. However, this traffic light exploded (爆炸) after 23 days. The light was turned off, but the idea stayed alive. In 1914, electric traffic lights were first used in America. Red and green still did their jobs; then they were safer and easier to see. In 1927, a Chinese student named Hu Ruding was studying in the US. He noticed drivers sometimes rushed when the light changed. “What if there’s a middle color to slow people down?” he thought. That’s how the yellow light was born, meaning “get ready to stop.” Around the same time, an American policeman named William Potts created the first three-color traffic lights for all directions. They made crossroads much safer. “What do the traffic lights mean?” Someone may ask. Red is easy to see, like a fire alarm, so it means “danger—stop!”. Yellow is a warning, like a sign that says “be careful—slow down!”. Green, like a forest, tells us “safe to go!” Together, they form a common language that keeps people safe every day. Great ideas come from everyday things. Whether traffic lights or something else, noticing and thinking “what if” can change the world! 1.

Some students think AI apps truly help a lot. They say these apps explain difficult problems clearly and make studying easier. However, other students disagree. They worry that using AI apps too often will make us lose the ability to think independently. Also, AI sometimes gives wrong answers, which may mislead us. In my opinion, AI apps can be useful tools, but we should use them wisely. We shouldn’t rely on them completely. Instead, we should use them to check our work and learn from the explanations, so that we can improve our studies effectively. ( 1 ) 学科网（北京）股份有限公司 $
