【推荐2】According to the World Health Organization, about 500,000 people get disabled each year and it is almost impossible for them to walk again, _____ after their body is seriously hurt. But scientists have made two disabled _____ walk again with a brain implant (植入物).

Professor Gregoire Courtine of the Swiss Federal Institute of Technology and his team _____ a special thing to help two monkeys whose legs were badly disabled. In order to make them walk again, the experts _____ an implant in the monkeys’ brains.

The implant is connected to the part of the body where the nerves (神经) are badly hurt. It’s like a bridge that _____ the brain and the body. It reads activity from the brain and then _____ this information to the body. That’s how the monkeys are _____ again to walk.

After getting the implant, one of the monkeys was able to _____ its disabled leg in the first week without training. _____ monkey took two weeks to do it, according to the research.

The human body is _____ to that of monkeys, so scientists believe that the technology could help humans in the next 10 years.

AI is becoming more and more powerful, which makes some people worry that they will lose their jobs to machines. Nowadays, companies have released AI that can answer questions, write articles and create images. Now, even people in ________ fields must think about the possibility of AI replacing them. However, many experts (专家) still believe that these AI programs can’t really take the place of human beings.

Using AI for certain tasks may be a good thing. Perhaps AI will take over less interesting work and it allows people to do more satisfying jobs. For example, washing machines save people a lot of time, so they can use that extra time productively. ________, AI may be able to take over dull tasks to let people do more proper thinking, since thinking up new ideas is something AI can’t do.

Another ________ for AI is human interaction (互动、交流). Most people prefer to communicate with humans rather than machines. Therefore, AI is unlikely to replace humans for jobs that require personal connection, such as advising or teaching. A robot can perform tasks, but it can’t truly care about others, and sometimes care is what people need.

AI can process data (数据) quickly, but it can only use data that it is given. So, it isn’t able to ________ situations that are quite different from those in its data. Therefore, although some AI programs can create content, ________ of them can be truly creative.

Finally, if AI receives wrong information, it has no way of recognizing or correcting it. Humans may also make mistakes, but life experience can make them learn from their mistakes. For the time being, AI does not have such an ability. ________, AI must continually check the data to make sure its conclusions are accurate.
