What do you probably want to do if you have a question? I’m sure you may want to get a quick answer on the Internet. But how can you make it? Now some technology companies are working to make this come true by developing chatbots. Chatbots can look up information, answer common questions and collect information from users. They can also be used for online shopping to help people choose things that they really need and then decide what to buy. There are two kinds of chatbots: open and closed. A closed chatbot may or may not use AI to understand messages from users. An open chatbot uses AI both to know what people want and to create a reply. Open chatbots are able to learn from their conversations and then improve their ability to communicate over time. This means that open chatbots can answer more different kinds of questions. Chatbots have many important advantages. One of them is that chatbots are available (可用的) all the time, even at midnight. What’s more, one chatbot can serve a large number of users at once. This means that people can get answers quickly instead of waiting for the reply of a human agent. However, chatbots can’t replace human agents. Someone has to program (编写程序) thechatbots at the beginning and train them. Sometimes, open chatbots can’t give answers to certain questions. Besides, quite a few people like speaking to a human better, not a chatbot. ( )1. How do open chatbots become better over time? A. By talking with people every day. B. By following the same program. C. By learning from conversations. D. By getting improved once a month. ( )2. According to the text, what can chatbots do? A. They can do whatever humans do. B. They can give 24-hour service. C. They can only answer easy questions. D. They can make decisions for humans. ( )3. What does the underlined word “them” in Paragraph 5 refer to? A. Computers. B. Chatbots. C. Human agents. D. Chatbot users. ( )4. What can we infer from the text about chatbots? A. They are more popular with old people. B. They might make some people lose their jobs. C. They will make online shopping prices go up. D. They can only understand a small number of words. V. 完形填空 It was the late 1980s. I was about three or four years old.
