In March 2026, a Chinese company(公司) signed two AI actors. They will star(主演) in a new AI­made show. This news quickly became a hot topic online, with many people sharing different opinions. Why do some people support AI actors? For film companies, AI actors can help save money. Making a short drama with AI costs only about 3,000 to 5,000 yuan,while a real­person drama costs far more than 5, 000 yuan. AI actors are not limited by time. They can work at any time and never feel tired. Some people think AI technology can help create new kinds of stories. However, many people are worried about AI actors. Some say AI actors look like real stars. This may bring problems with image rights. Others feel AI actors look strange. Their faces seem to be a mix of different real actors' faces, and their acting feels cold and without real feelings. One viewer said，“They have no soul.” There is also worry about jobs. If AI actors become common, many real actors playing small roles may lose their jobs. A famous producer said that while AI may be popular now, people will always love watching real actors tell real stories. The discussion shows us an important question: as technology grows fast, how do we keep the human touch in art? 76. What will the two AI actors star in? _________________________________________________ 77.Why do film companies support AI actors? _________________________________________________ 78.Who can work at any time and never feel tired? _________________________________________________ 79.How do many people feel about AI actors? _________________________________________________ 80.
