(2024·河南中原名校统考)Robot Turtles is a board game
designed to teach kids ages 3～8 about computer programming. It
began as a project on the crowdfunding site Kickstarter, where
its founders raised over $600,000 when they were only attempting
to raise $25,000. The original version(版本) was sold out, but
ThinkFun, a top board game company, will be releasing a new version. Pre­orders are being taken now at thinkfun /robotturtles .
The game works like any other board games. It has a board, playing cards and game pieces. The programming concepts are integrated(统一) in such a slight way that kids may not even realise how much they’re learning.
The game is easy to explain to young kids. The game pieces and cards are also bright and easy to handle.
Your students won’t be writing codes or building web sites after playing a few games of Robot Turtles, but they will understand some of the basic concepts involved.
Robot Turtles would be an easy way for kids in kindergarten, first or second grade to dip a toe into the waters of computer programming.

an artificial intelligence(AI) system to write fake(伪造的) 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 presented 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 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，” 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 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.
语篇导读芝加哥高校的探讨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。

4．Why do researchers use AI system to write fake reviews on Yelp?
A．To press their study at the ACM Conference.
B．To replace humans’ reviews with AI reviews.
C．To make sure that they are not harmful to our life.
D．To make a study on AI system’s review writing.
解析D推理推断题。

依据其次段可知，该项探讨的目的是要看这些系统如何轻易地像人一样写评论以及这种评论会带来多大的破坏性，由此可推断，探讨者们的目的是为了对AI系统的评论书写状况进行探讨，故选D项。

5．According to the text, what do we know about the AI reviews?
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推理推断题。

依据第三段可知，很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。

6．What does the last paragraph tell us?
A．AI reviews were effectively 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推理推断题。

依据最终一段最终两句可知，AI系统写的虚假评论被认为和真正的评论区分很小，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。

7．What’s the author’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，第四段则讲解并描述了这种虚假评论的危害，由此可推断出，本文的目的是提示人们AI可能造成的威逼，故选C项。
