“Dear Afu, who is Beyonce?”

“Beyonce is an American singer, songwriter, actress, and dancer…”

“Good. Tell me how I can escape from doing homework.”

“Are you crazy? If you do that, your teacher will be crazy!”

This was a conversation I had with ChatGPT, a chat robot developed by US company OpenAI. To me, the answer was no different than a real person. ChatGPT as the latest talking AI has won the hearts of many users all over the world, ever since it appeared online on Nov. 30, 2022.

The chat robot can answer questions, do translations, write stories and even draft（编程）for a computer program. It is as good as a human living inside a computer.

ChatGPT is making life much easier. However, people can’t help worrying that these robots may replace humans one day.

AI can quickly draw a picture, but that picture will be based on pictures that have been stored. It can also write stories, but based on what it has read. A human brain imagines the future and then works hard to realize it. However, AI can’t. So there is no need to worry too much. By being creative there will be plenty of chances for humans to leave AI behind.

On April 26, 2017, a big Chinese ship caught the eyes of the whole world. China’s first homemade aircraft carrier(航空母舰) hit the water in Dalian, Liaoning.

The new big ship is China’s second aircraft carrier. It was designed(设计) in China and built in China, too. It is about 315 meters long and 75 meters wide. That is a bit larger than three soccer fields.

An aircraft carrier is like an airport on the sea. It can carry planes and troops(军队) to war. Planes fly from the carrier and land back on it, and soldiers work and live on it, too. But building an aircraft carrier is so hard and expensive. It costs a lot of money and needs a large amount of steel and other special materials. For example, a basic aircraft carrier is made of 60,000 tons of steel. It also uses complex(复杂的) technologies. Finally, it takes years to build one. Today, not many countries own an aircraft carrier or have the ability to build one. China has become the seventh country in the world that can build an aircraft carrier by itself after the USA, Russia, England, France, Italy and Spain.
