Some people may say no, but many experts think we should use it in a good way. They say AI can help us learn better. Zheng Qinghua, president of Tongii University, said it was important for us to use AI in education. He believed that AI could help us learn new things and get better at what we study. He also suggested that young people should improve their understanding of the knowledge through technology. In fact, AI has already become more and more important for teaching and learning. Zheng talked about the common use of different AI tools. These AI tools can help with students’ homework. A survey made by an online learning platform (平台) showed that 89 percent of students had used AI tools to help them with homework. However, some people worry that it may bring bad influence on education. “Instead of just using AI to get answers or finish homework and tests, students should focus on using AI to become creative and develop the ability to solve real-world problems,” said Zheng. Colin Bailey, president of Queen Mary University of London, says that as AI develops fast, stopping AI from being used in schools is not the answer. Instead, we should think about how to use it safely and correctly. People all over the world are working on rules to make sure AI is used in a good way. 1．What did Zheng Qinghua think of using AI in education? Zheng Qinghua thinks 2．How should students use AI according to Paragraph 4?
