3 . One of the easiest things in the world is to become a fault-finder. However, life can be great when you are not busy finding fault with it.

Several years ago I _________ a letter from seventeen-year-old Kerry, who described herself as a world-class fault-finder, almost always _________ by things. People were always doing things that annoyed her, and _________ was ever good enough. She was highly self-critical and also found fault with her friends. She became a really boring person.

Unfortunately, it took a horrible accident to change her _________. Her best friend was seriously hurt in a car crash.

4 . ChatGPT, an artificial intelligence-driven chatbot (聊天机器人) programme that responds to user prompts, has gone viral in social networks in recent weeks. Its ___________ is such that within days of its launch, OpenAI, the artificial intelligence company behind the chatbot, announced that 1 million people had used. In comparison, Facebook and Spotify took months to achieve that ___________of engagement (受人关注) . The attraction is obvious: ChatGPT can produce jokes, essays and computer code from a short writing prompt.

There’s nothing ___________ in software that produces fluent and logical writing. ChatGPT’s predecessor (前身), the Generative Pretrained Transformer 3 (GPT-3), could do that too. Both were trained on an unimaginably large amount of data to answer questions in a/an ___________ way. But ChatGPT has been updated by being given the data on human “conversations”, which significantly ___________ the truthfulness and informativeness(信息准确性) of its answers.

___________, ChatGPT still produces answers that seem reasonable but are incorrect or nonsensical (无意义的). Even the chatbot itself says, “My responses are not intended to be considered as ___________.” This might be a big problem on the Internet, as many web platforms (平台) ___________ the ability to protect themselves against a flood of AI-generated content (AI生成的内容). Such websites as Stack Overflow, where users can find answers to programming-related questions, had to ban ChatGPT-produced posts, as its human moderators (管理员) could not ___________ the volume (大量) of incredible but wrong replies.

While OpenAI has safeguards to refuse inappropriate requests, such as to tell users how to commit crimes (犯罪), these can be bypassed. AI’s potential for harm should not be ______________. In the wrong hands, it could be a weapon to harm people and society.

No one knows what will happen to such technologies if the software engineers of the future will themselves be software programs. “Human supervision (监督) and ______________ are required,” OpenAI’s researchers have warned.
