1After waking up, you may feel frustrated because you cannot recall the dreams you had last night.Artificial intelligence(AI)may be able to help.

2Previously,there have been AI models that can turn texts into images.They do this by learning from a large amount of data from both texts and images.This time,researchers from Japan have developed an AI system called Stable Diffusion to recreate images based on people's brain scans,Sciencemagazine reported.

3The researchers used an online data set provided by the University of Minnesota,which consisted of brain scans from four participants after they each viewed a set of 10,000 photos.The scans were recorded by functional magnetic resonance(磁共振)imaging.

4The AI then learned about the brain activities by analyzing changes in blood flow shown by the fMRI data——when a part of the brain is activated,more blood will flow to it.It then matched the brain activity with the photos.Through this method,AI learned how human brains would react when seeing different photos.

5Finally,the researchers tested the AI on additional brain scans from the same participants when they viewed photos of a toy bear,airplane,clock and train.

6If the person looked at an airplane,for example,the AI would use the brain scan data to create an image of a very blurry airplane.Then,it would turn on the previous“text-toimage”model and improve the quality of the image by feeding itself the keyword“airplane”.

7The final images were“convincing”to about 80 percent accuracy,according to the researchers.The new study created a novel approach that combines texts and images with“deciphering(破譯)the brain”.

8In the future,scientists hope the technology can be used to record imagined thoughts and dreams or allow people to become familiar with how differently other animals perceive reality.

?語篇解碼

本文是一篇說明文，主題語境為人與社會，話題為科技發展。在電影《盜夢空間》中，一群特工進入他人的夢境，從而竊取他人潛意識中的機密，并重塑他人的夢境。

現在，這樣讀取他人夢境的科幻場景可能通過AI就能實現了。

?語言學習

Ⅰ.語料薈萃

Ⅱ.語句分析

1.After waking up,you may feel frustrated because you cannot recall the dreams you had last night.你可能會因為醒來后不記得昨晚做的夢而感到沮喪。

【點石成金】本句是一個主從復合句。you may feel frustrated 是主句，After waking up 是介詞短語作時間狀語，because you cannot recall the dreams 是原因狀語從句，you had last night是省略了關系代詞that或which的限制性定語從句。

2.The researchers used an online data set provided by the University of Minnesota,which consisted of brain scans from four participants after they each viewed a set of 10,000 photos.研究人員使用了明尼蘇達大學提供的在線數據集，其中包括四名參與者在每人觀看了一組1萬張照片后進行的大腦掃描。

【點石成金】本句是一個主從復合句。The researchers used an online data set 是主句，provided by...Minnesota 是動詞-ed形式短語作定語，which consisted of brain scans是非限制性定語從句，after they each viewed a set of 10,000 photos 是時間狀語從句。
