1. (2023高一下·马鞍山月考)  阅读理解

Doctors at the University of California, San Francisco, in the US, have developed a piece of software that can read minds. The project, supported by Facebook, hopes to help people who, because of medical conditions, are unable to communicate with others. 

Until now, various technologies have been invented to help those speech-impaired (语言障碍) people to communicate with others naturally. According to previous study, almost 30% of Americans once found themselves upset and even anxious to use oral language fluently. This new software uses brain signals to change a person's thoughts into text. When we want to speak, the brain sends signals to make the lips, jaw and tongue move in the right way to make an understandable sound. By discovering these brain signals, the new software is able to predict what a person want to say quickly enough to hold a conversation.

The brain-reading software was tested on three volunteers who could all speak like healthy people. They were being treated for epilepsy(癫痫). As part of their treatment for epilepsy, each patient had electrodes(电极)placed on to their brain. Edward Chang, a researcher of the study, used these electrodes to record the signals in the patients' brains while they listened to a list of questions and answered them.

Chang and his team then built a computer program that learned to match the patients' brain signals to the words the patients heard and the words the patients spoke. For the questions, the software matched the correct words 76%of the time. For the answers, it matched the correct words 61%of the time.

Now, the mind-reading software is still limited in certain areas where it was trained. Scientists hope that they will develop a more powerful one that could understand thoughts in real time to give people their voices back. Chang said, "We as scientists should try our best to help people to bring that most important and basic human ability back even if facing challenges"
