Ⅴ. 阅读表达（阅读短文，简略回答问题） In today’s digital world, people want answers fast. To help, big tech companies are creating chatbots using AI. Chatbots are smart programs that can talk to us on phones, messaging apps and websites and give quick replies to our questions. Chatbots have changed how we get information and shop online. They can do many things, like learning new knowledge, giving helpful suggestions and solving technical problems. This makes them very useful in our busy digital lives. There are two types of chatbots: open and closed. Closed chatbots use prewritten answers for common questions. Open chatbots, however, use advanced（先进的）AI to understand what we want and give the right replies. They also learn from each conversation, becoming better at answering different kinds of questions over time. The great thing about chatbots is that they can be used at any time. And they can help many people at once, so we don’t have to wait long for answers. But chatbots aren’t perfect. Some questions are too difficult for chatbots to answer, that’s why they need humans to train them. Besides, they can’t understand human feelings well. Many people still prefer talking to real persons. Chatbots have made online services faster and more convenient. But they can’t work best without working together with humans. By combining AI-powered chatbots and human skills, we get a better customer（顾客）service experience that’s both quick and understanding. As we move forward in this digital age, using chatbots and human intelligence together will shape how we interact（互动）with technology in the future. 1. What are chatbots? ____________________________________________________________________________ 2. What have chatbots changed according to the text? ____________________________________________________________________________ 3. Why do chatbots need humans to train them? ____________________________________________________________________________ 4. How can chatbots work best? ____________________________________________________________________________ 5. Which of the two types of chatbots do you think is better to use?
