The creator of ChatGPT, OpenAI, has announced(公布)its latest upgrades(升级). The changes allow some users to directly ask ChatGPT questions and get voice answers. Also, ChatGPT can read images(图像) and give information about what is in them. 2When you ask ChatGPT questions, it can speak in the way that you feel like talking with a human. It can also tell a story to children or provide detailed steps for making or building. 3 Users can choose different voices they want the chatbot to use. OpenAI works closely with professional voice actors to make the interactions more realistic and personal. 4 Another big change to ChatGPT is image recognition. For example, you could take a picture of what is in your fridge. After you send the photo into ChatGPT, it can tell you what dishes you can make for dinner and how to cook them step by step. 5 Another example is that a parent might send a picture of a child's Maths problem and then get advice on how to teach the child to work it out through ChatGPT. There is even a way for users to mark on the image, for example with a circle, to get more information or help. Now the new upgrades can only be used by the users of ChatGPT's Plus and Enterprise services. ChatGPT's main service, called GPT-3.5, is free for all users. ChatGPT Plus costs $20 per month. The Enterprise service is used by companies. Other groups of users can have the new upgrades in the near future. 7Along with its announcement, OpenAI advised all its users to be careful about the information given by ChatGPT. That's because the system is trained by a huge amount of information, some of which may be out of date or even wrong. 1. Which sentence can be put in the " "? A. Besides, the chatbot can draw images. B. In fact, you can talk with ChatGPT anywhere. C. ChatGPT is used by users of all ages. D. But the chatbot can do more than answer questions. 2. How does the writer show the new changes of ChatGPT in image recognition? A. By using numbers. B. By giving examples. C. By sharing users' ideas. D. By giving survey results. 3. What can we infer from the passage? A. Users cannot choose voices they want the chatbot to use by now. B. The chatbot can make dinner for you. C. All users can use the new upgrades of ChatGPT now. D. Users may get wrong information from ChatGPT. 思维导图 Daniel制作了一张思维导图来分析ChatGPT的功能，我们来帮他补充完整吧！（每空不限一词） III. 自动驾驶 能自己思考的自动驾驶汽车逐渐走进人们的视野，Daniel思考它是否安全。 (2025·淮安二模改编)Self-driving cars do not have people telling them what to do. 1.______ That is learning about the environment, deciding what to do next, and taking action. First, the car needs to know what is around it. It uses many different sensors(传感器)to do this. These sensors, such as cameras and radar, are like the car's "eyes". 2.__________.The sensors also help the car know where and how fast it is going. 3.____________.This is where "Vehicle to Everything(V2X)" comes in. This technology connects a self-driving car with people and things. It also allows the car to go online. All these things help the car "talk" with the outside world and get the latest road information. After receiving the information, the car needs to read it, has to"think" and decide what to do. So it combines(合并)the information from all sensors. This process(过程)is called multi-sensor fusion(多传感器融合). Machine learning plays an important role here because it helps the car recognize people and objects. 4.___________ Finally, to carry out decisions, the car uses drive-by-wire technology. 5._____________.This makes different parts of the car respond(反应)quickly. The car also uses less oil this way, which is good for the environment. A. Then, the car can decide when to stop, go, or turn B. They move themselves about safely by doing three things right C. Cool technologies help self-driving cars"see","talk" and "think" D. They allow the car to "see" things such as people and traffic lights E. Bringing together information is just like putting together the pieces of a puzzle(拼图) F. It allows the car to give orders to its wheels, brakes (刹车)and engine in the form of electronic signals G. Besides knowing what is around it and where it is going, a self-driving car makes plans ahead to avoid traffic accidents Questions: What problems in life can self-driving technology solve? And what risks might it bring?
