ChatGPT remembers the thread of your dialogue, using previous questions and answers to inform its next responses.It derives its answers from huge volumes of information on the Internet.ChatGPT is built on top of the OpenAI GPT-3 family of large language models and is fine-tuned(a method of transfer learning) using both supervised and reinforcement learning(监督和强化学习)． You can ask ChatGPT anything, like explaining physics, asking for birthday party ideas and getting programming help.Perhaps it's not smart enough to replace all humans yet, but it can be creative, and its answers can sound downright authoritative.A few days after its launch, more than 1 million people were trying out ChatGPT.UBS analyst Lloyd Walmsley estimated in February 2023 that ChatGPT reached 100 million monthly users in January, accomplishing in 2 months what took TikTok about 9 months and Instagram two and a half years. ChatGPT is free to use at the moment because it is still in its research phase.But when too many people hop onto the server, it overloads and can't process your request.It just means you should try visiting the site at a later time when fewer people are trying to access it.If you want to skip the wait and have reliable access, there is an option for you.As of Feb.1, 2023, OpenAI has a ChatGPT pro plan, ChatGPT Plus, which allows users to have general access even during peak times.This service does come at a cost of $20/month. However, ChatGPT cannot replace Google.ChatGPT is an artificial intelligence robot that provides solutions to your questions, but Google is a search engine in which you can search for as much information as possible.ChatGPT has limited knowledge due to its programming but Google has unlimited knowledge which is updated every day. 语篇导读 主题语境：人与社会/科学与技术。本文为说明文，介绍了ChatGPT的出现和市场反应，并对它的优点及弊端进行了分析。 5．What does Paragraph 2 mainly tell us about ChatGPT?

D．To prove the necessity of developing tools for chatting online. 答案　A 解析　推理判断题。本段所列数字显示ChatGPT非常受欢迎，故选A项。 7．What is ChatGPT Plus intended for? A．Guiding users to experience free services. B．Giving users priority access during peak hours. C．Allowing net surfers to skip advertisements. D．Helping researchers detect the failure of the system. 答案　B 解析　细节理解题。根据第四段后两句可知，设计ChatGPT Plus的目的是在高峰时段给予用户优先访问权，故选B项。 8．What is a limitation of ChatGPT compared with Google? A．It may provide replies unrelated to the questions. B．It can only update information at a fixed time. C．It needs longer to provide solutions.
