Hi Sandra,
You’ll never guess over I’m writing this email from a cave! We’re on holiday in Spain now. We spent a few days in Barcelona first. It’s a great place but we had a good time though I didn’t feel well one day. Anyway, after we left Barcelona, we come to spend several days in Granada. And guess what? We couldn’t find a hotel because there were quite a lot of tourist. Then someone said, “Why not trying the cave dwellings（住宅）here?” We thought he was joking, but here we were really in a cave dwelling and it’s wonderfully. Tomorrow we’re going to visit a palace in Granada. We’ve enjoying it very much that we don’t want to leave this amazed place. We’re never going to have enough time explore everything!
Take care!
Ben

In the villages of Mexico, as in some other parts of the world, shopping is a kind of game. In the fine department stores, of course, buyers pay the prices listed on the tags（标签）. 1.
Suppose a merchant is a Mexican shopkeeper who sells handmade silver jewelry to tourists. 2. The merchant names a price. Immediately the tourist makes a much lower offer. The price the merchant puts on an article is not usually the price which will finally be paid. But the merchant pretends to be shocked. 3. It takes a long time to make such remarkable earrings. But at great sacrifice the merchant will let the tourist have the earrings at a lower price. The two bargain. The tourist comes up a little, and then the merchant comes down a little. At last they agree on what both consider to be a fair price.
4. The merchant may talk about life in the village or mention interesting sights the tourist should see before leaving Mexico.
The merchant’s way of doing business is much older than the supermarket way. It dates back to Old World times when the town market was the only place where people could exchange news and visit with friends. 5.
In Mexico today, bargaining still makes life interesting for some merchants.
A. The buyers found bargaining really interesting.
B. Bargaining made their lives a little more colorful.
C. While the two bargain, they speak of other things as well.
D. Among the items of jewelry is a pair of earrings a tourist wants to buy.
E. But in most villages, bargaining is a game both buyers and sellers enjoy.
F. While in mountain areas, the buyers and sellers have to bargain every day.
G. The tourist is told that the earrings are real silver, made by people living in the mountains.
Researchers at the University of Chicago have trained an artificial intelligence (AI) 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 pressed at the ACM Conference on Computer and Communication 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 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 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.
1.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 research on AI systems review writing.
2.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.
3.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'.
4.What’s the author’s purpose of writing the passage?
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 from AI’s fake remarks.
D. To tell the differences between AI reviews and humans'.
