题组B 提升练 Ⅰ.阅读理解

Researchers at the University of Chicago have trained an artificial intelligence system, to write

fake 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 throw attention onto how easily these systems can

write reviews like humans and how damaging they can become if they're not monitored properly.

Since many small businesses rely on online reviews to help grow and keep their reputation, a

future where someone—like a rival or angry customer—could crazily fill their page with negative

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 towards 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 unimaginable.”

To test how believable these reviews came across, the researchers invited 40 volunteers and

had AI generate five fake reviews for 40 actual restaurants. The volunteers were asked how useful

they thought the review was and whether or not they thought it was 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.

1．What can the new artificial intelligence system do according to the passage?

A．It can help train new reviewers.

B．It can tell the real reviews from the fake ones.

C．It can write human-like reviews.

D．It can easily damage the businesses.

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 who can control you from distance.

3．What can we infer from Ben Y. Zhao's remarks?

A．Artificial intelligence can put the society in danger.

B．The artificial intelligence is only used by the researchers.

C．Ben Y. Zhao is optimistic about the further development of artificial intelligence.

D．The artificial intelligence will help people shake.

4．What is the best title for the passage?

A．Suggestions on giving reviews

B．How to tell the fake reviews

C．Development of AI in review on Yelp D．AI is coming to steal your reviews

【语篇解读】这是一篇说明文。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， 而威胁远远不止于此。

1．C 细节理解题。根据文章第一段 “Researchers at the University of Chicago have

trained an artificial intelligence system … and it's pretty hard to tell them apart from a human

review.”可知， 芝加哥大学的研究人员研发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．B 词义猜测题。根据文章第三段 “Since many small businesses rely on online reviews

to help grow and keep their reputation … their page with negative reviews written by a machine is
