6、ficial intelligence system to write fake(虚假的)reviews on Yelp,a website showing customers reviews on shopping or something else,and its 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

7、 to stress how easily these systems can write reviews like humans and how damaging they can become if theyre not monitored properly.Since many small businesses rely on online reviews to help grow and keep their reputation,a future where someonelike a rival or angry customercould crazily fill their p

11、芝加哥大学的研究人员已经培训出了一种人工智能(AI)系统,在Yelp网站上编写虚假评论,足以乱真。其目的是强调这些系统可以很容易地写出像人类写的一样的评论,如果它们没有被恰当地运用,它们会变得具有破坏性,而威胁远远不止如此。1.Whatcanthenewartificialintelligencesystemdoaccordingtothepassage?A.Itcanhelptrainnewreviewers.B.Itcantelltherealreviewsfromthefakeones.C.Itcanwritehuman-likereviews.D.Itcaneasilydamageth

12、ebusinesses.答案C解析细节理解题。根据文章第一段可知,芝加哥大学的研究人员培训了一种人工智能系统,让它在Yelp网站上撰写虚假评论,很难把它们与人类的评论区分开。由此可知,这种新的人工智能系统可以撰写出像人类写的一样的评论。2.What does the underlined word “rival” mean in the passage?A.A person who respects you deeply.B.A person who competes with you.C.A person who loves to give fake reviews.D.A person w

13、ho can control you from a distance.答案B解析词义猜测题。根据文章第三段可知,由于许多小企业依赖在线评论来帮助成长和保持声誉,未来有人可能会疯狂地用机器写的负面评论填满它们的页面,这是相当令人担忧的。由此可知画线单词所在部分likearivalorangrycustomer是someone的同位语,对其进行解释说明。根据上下文语境以及生活常识可以判断出,企业面对的是顾客和竞争对手两类人。因此rival可以理解为竞争对手。3.What can we infer from Ben Y.Zhaos remarks?A.Artificial intelligence
