Since many small businesses rely on online reviews to help grow and support their reputation, a future where someonelike a competitor or angry customercould crazily fill their page with bad reviews written by a machine is pretty worrying. And, according to the research team, the threat goes far beyond a bunch of fake reviews on Yelp. “In general, the threat is bigger，” Ben YZhao, one of the authors of the study, said. “I think the threat toward society is large and it really misleads users and shakes our belief in what is real and what is not. I think thats going to be even more unimaginable.” To test how believable these reviews came across, the researchers invited 40 volunteers and had AI generate(生成) five fake reviews for 40 actual restaurants. The volunteers were asked how useful they thought the reviews were and whether or not they thought they were fake. The AI reviews ranked as “effectively indistinguishable” from real reviews, according to the study. Further, the fake reviews were given a 3.15 “usefulness” rating, compared to a 3.28 rating for human reviews.语篇导读芝加哥大学的研究者们研发了一种可以在网上写虚假评论的AI系统。本文介绍了这种系统的由来、可能存在的危害等。4Why do researchers use AI system to write fake reviews on Yelp?

AThey can be found everywhere.BThey are hardly helpful to our life.CThey can be vital to small businesses.DThey bring us a lot of convenience.解析C推理判断题。根据第三段可知，许多小企业依靠网上的评论来提高声誉，从而促进其发展，所以AI系统写的评论对小企业来说很重要，故选C项。6What does the last paragraph tell us?AAI reviews were effectively distinguishable.BAI system was really a help in review writing.CRestaurants should care for customers reviews.DAI reviews were almost as believable as humans.解析D推理判断题。根据最后一段最后两句可知，AI系统写的虚假评论被认为和真正的评论区别很小，前者的识别率是3.15，后者的是3.28，由此可推知，AI系统写的评论几乎和人写的评论一样可信，故选D项。7Whats the authors purpose of writing the text?ATo emphasize the importance of AI studying.BTo predict what the world will be like tomorrow.CTo warn people of the threat AI will possibly make.DTo tell the differences between AI reviews and humans.解析C写作意图题。文中介绍了AI系统所写的评论可以以假乱真，第四段则讲述了这种虚假评论的危害，由此可推断出，本文的目的是提醒人们AI可能造成的威胁，故选C项。 完形填空课标话题人与自我优秀品行体裁记叙文词 数 282难度 (2019大连双基检测)LoAnna and Kris kids were playing outside on a sunny Saturday.
