7、2019·山東勝利一中質(zhì)檢)Researchers at the University of Chicago have trained an artificial intelligence(AI) system to write fake(偽造的) reviews on Yelp, a website showing customers’ reviews on shopping or something else, and it’s pretty hard to tell them apart from a human review. Their study, which will be p

8、resented at the ACM Conference on Computer and Communications Security in October, aimed to stress how easily these systems can write reviews like humans and how damaging they can become if they’re not mentioned properly. Since many small businesses rely on online reviews to help grow and support

9、their reputation, a future where someone—like a competitor or angry customer—could 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，”

10、Ben Y．Zhao, 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 that’s going to be even more unimaginable.” To test how believable these reviews came across, the researchers i

11、nvited 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 st

14、views? A．They can be found everywhere. B．They are hardly helpful to our life. C．They can be vital to small businesses. D．They bring us a lot of convenience. 解析　C　推理判斷題。根據(jù)第三段可知，許多小企業(yè)依靠網(wǎng)上的評論來提高聲譽，從而促進其發(fā)展，所以AI系統(tǒng)寫的評論對小企業(yè)來說很重要，故選C項。 6．What does the last paragraph tell us? A．AI reviews were effect

15、ively distinguishable. B．AI system was really a help in review writing. C．Restaurants should care for customers’ reviews. D．AI reviews were almost as believable as humans’. 解析　D　推理判斷題。根據(jù)最后一段最后兩句可知，AI系統(tǒng)寫的虛假評論被認為和真正的評論區(qū)別很小，前者的識別率是3.15，后者的是3.28，由此可推知，AI系統(tǒng)寫的評論幾乎和人寫的評論一樣可信，故選D項。 7．What’s the author’

16、s purpose of writing the text? A．To emphasize the importance of AI studying. B．To predict what the world will be like tomorrow. C．To warn people of the threat AI will possibly make. D．To tell the differences between AI reviews and humans’. 解析　C　寫作意圖題。文中介紹了AI系統(tǒng)所寫的評論可以以假亂真，第四段則講述了這種虛假評論的危害，由此可推斷出
