▍原文 For the first time, an artificial intelligence system has created a series of previously unknown viruses capable of infecting and eliminating certain types of bacteria. US researchers said they successfully directed an AI model to create a collection of simple viruses that only infect bacteria and pose no threat to humans. This breakthrough opens up new possibilities for combating bacterial resistance. However, it also raises concerns about the potential misuse of this technology to design biological weapons. ▍語言點 1. artificial intelligence 人工智能（AI） 2. previously unknown 前所未見的，自然界原本不存在的 3. capable of doing something 能夠做某事，具備……的能力 4. infect /ɪnˈfekt/ v. 感染 5. eliminate /ɪˈlɪmɪneɪt/ v. 消滅，清除 6. direct /dɪˈrekt/ /daɪˈrekt/ v. 操控，指引 7. a collection of 一系列，一批 8. pose no threat to 對……不構成威脅 9. breakthrough /ˈbreɪkθruː/ n. 重大突破 10. combat /ˈkɒmbæt/ /kəmˈbæt/ v. 對抗，攻克...
