四、阅读理解
Scientists have developed a way to read minds, translating unspoken thoughts into written words. It's the first time it's been done without having to put anything into the brain. They used AI(artificial intelligence，人工智能). It is the name given to a computer system that is able to “think” for itself and carry out tasks that usually require human intelligence.
Scientists used a special scanner(扫描器). The machine can see where blood runs, which shows the parts of the brain that are most active. People taking part in the experiment(实验)listened to the radio for 16 hours as their brains were scanned. The AI tool learned to connect certain brain activity with words they heard. After that, each person was asked to think of a story, and the AI tool managed to pick up these thoughts as they happened.
The results had about a 50% accuracy rate(准确率)，although the AI found it hard to work out the meaning of pronouns, such as “he” or “she”，“her” or “him”. For example, it turned “I don't have my driver's license yet.” into “She has not even started to learn to drive yet.” It could usually understand the meaning of what someone was thinking rather than the exact words. The AI was personalized, so when it had learnt from one person but was tested on another, it couldn't understand their thoughts.
The scientists, who have been working on the technology for 15 years, say they understand the risks of it being used badly. Scientist Jerry Tang told a newspaper, “We want to make sure people only use these types of technologies when they want to, and that it helps them.” The scientists hope it will help people with certain medical conditions, who are still awake but have lost the ability to speak, to communicate once again.

### 四、阅读理解
科学家们研发出了一种读取思维的方法，能将未说出口的想法转化为文字。这是首次在无需向大脑中植入任何东西的情况下实现该操作。他们运用了人工智能（AI，即artificial intelligence）。人工智能是对一种计算机系统的称呼，该系统能够自主“思考”并执行通常需要人类智慧才能完成的任务。
科学家们使用了一种特殊的扫描仪。这种机器能够观测到血液的流动情况，而血液流动情况能显示出大脑中最为活跃的部分。参与实验的人们在大脑被扫描的过程中听了16个小时的广播。人工智能工具学会了将特定的大脑活动与人们听到的词语建立联系。之后，每个人都被要求构思一个故事，而人工智能工具在这些想法产生的过程中成功捕捉到了它们。
结果的准确率约为50%，不过人工智能发现很难弄清楚代词的意思，比如“他”或“她”、“她的”或“他的”。例如，它把“我还没有驾照。”转换成了“她甚至还没开始学开车呢。”它通常能够理解人们所想内容的意思，而非确切的文字表述。这种人工智能具有个性化特点，所以当它从一个人身上学习后，在对另一个人进行测试时，就无法理解那个人的想法了。
从事这项技术研究已有15年的科学家们表示，他们明白该技术被滥用的风险。科学家杰瑞·唐告诉一家报纸：“我们想要确保人们只在他们想要的时候使用这类技术，并且这类技术能对他们有所帮助。”科学家们希望它能帮助那些患有特定疾病、仍然清醒但已失去说话能力的人再次进行交流。
