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(破译)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.

➢语篇解码

本文是一篇说明文，主题语境为人与社会，话题为科技发展。在电影《盗梦空间》中，一群特工进入他人的梦境，从而窃取他人潜意识中的机密，并重塑他人的梦境。

现在，这样读取他人梦境的科幻场景可能通过AI就能实现了。

➢语言学习

Ⅰ.语料荟萃

Ⅱ.语句分析

1.After waking up,you may feel frustrated because you cannot recall the dreams you had last night.你可能会因为醒来后不记得昨晚做的梦而感到沮丧。

【点石成金】本句是一个主从复合句。you may feel frustrated 是主句，After waking up 是介词短语作时间状语，because you cannot recall the dreams 是原因状语从句，you had last night是省略了关系代词that或which的限制性定语从句。

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.研究人员使用了明尼苏达大学提供的在线数据集，其中包括四名参与者在每人观看了一组1万张照片后进行的大脑扫描。

【点石成金】本句是一个主从复合句。The researchers used an online data set 是主句，provided by...Minnesota 是动词-ed形式短语作定语，which consisted of brain scans是非限制性定语从句，after they each viewed a set of 10,000 photos 是时间状语从句。

➢语言运用

Ⅰ.例句仿写

1.我已经下定决心大学毕业后去农村教英语。

I have made up my mind to go to teach English in the countryside________________.

2.我的英语老师建议我买一本英汉词典，他认为这对我的学习会有很大帮助。

My English teacher recommended buying an English-Chinese dictionary,__________________.

Ⅱ.写作实践

假定你是校学生会主席，学生会准备开展一次“人工智能与未来教育”的专家讲座活动，请你写一份书面通知，内容包括：
