A special laboratory at the University of Chicago is busy only at night. It is a dream laboratory where researchers are at work studying dreamers. Their findings have discovered that everyone dreams from three to seven times a night, although in ordinary life a person may remember none or only one of his dreams.
While the subjects—usually students—sleep, special machines record their brain waves and eye movements as well as the body movements that signal the end of a dream. Surprisingly, all subjects sleep soundly.
Observers report that a person usually fidgets(烦躁不安) before a dream. Once the dream has started, his body relaxes and his eyes become more active, as if the curtain had gone up on a show. As soon as the machine shows that the dream is over, a buzzer wakens the sleeper. He sits up, records his dream, and goes back to sleep—perhaps to dream some more.
Researchers have found that if the dreamer is wakened immediately after his dream, he can usually recall the entire dream. If he is allowed to sleep even five more minutes, his memory of the dream will have disappeared.

Li Bingyin is now studying law at the Stern School of Business at New York University. She wrote this letter just before hurricane Sandy destroyed the East Coast.
Dear readers,
The storm will really take a toll on the city! Right now I am sitting in my dormitory（寝室）, waiting for the blackout（停电）to come any second, and listening to the wind howl outside my windows. Hurricane Sandy is supposed to hit the East Coast hard today. Due to the bad weather, most schools and universities have canceled classes for Monday and Tuesday.
Luckily, the university has taken steps to prepare for this storm. University officials sent out e-mails with explanation in the case of a blackout, evacuation（撤离）, or other emergency. Just recently, I received several text messages from the school about power off in certain dormitories. They advised us to prepare a bag with essentials（生活必需品）, in case we needed to leave the building and move to a safer place.
Yesterday I went out to buy a flashlight(手电筒), but all of the nearby stores were sold out. Everyone was storing water, food and other supplies for the storm.
Right now the city is unusually quiet. On any other day, there would be the sounds of cars, people chatting, and street artists performing. Tonight, there’s just the wind and rain hitting the window. The subway system has been closed since last night, and there is nobody on the streets. Hopefully Hurricane Sandy will soon pass without leaving much damage
Sincerely,
Li Bingyin

A team of researchers at the University of Illinois at Chicago found that too many kids are eating too much pizza and too many calories are doing harm to children’s health.
“There are a lot of takeaways from the study. But the biggest thing is that parents are serving their kids too much pizza,” said Dr.William Dietz, one of the study’s authors and the director of the Sumner M. Redstone Global Center for Prevention and Wellness at the Milken Institute of Public Health at the George Washington University.
The researchers used data from the National Health and Nutrition Examination Survey, which tracked the diets of more than 11,000 children and teenagers. Researchers figured how many children eat pizza in the United States, how often they eat it, and how much they eat when they do.
Pizza, pretty alarmingly, is the second leading source of calories in the diets of America’s children, next only to grain desserts, such as cookies and other sweets. On any given day, roughly 20 percent of all children aged 2 to 11 and adolescents aged 12 to 19 eat pizza. And when they do, they eat a lot of it. When children eat pizza, they eat roughly 400 calories, according to the study. For teenagers, it’s upwards of 600 calories.
All that is pretty problematic, according to Dietz largely because kids don’t tend to balance the pizza slices with salads, vegetables and other more nutritional(有营养的) foodstuffs. Days on which children and teenagers eat pizza are not only associated with considerably higher intakes of fat, but also, quite simply, with more food: on average, children consume 84 extra calories on the days they eat pizza, while adolescents consume an extra 230 calories.
“When you eat extra calories and don’t compensate(抵偿) for them at another point of the day or week, it can lead to weight gain and even obesity.”Dietz said.
There is a Silver lining. Pizza consumption is still too high by nutrition standards, but it’s lower than it used to be. Consumption(消费) fell by roughly 25 percent between 2007 and 2016, according to the study. Much of that has come at dinner where it's fallen by 40 percent for children and about 33 percent for teenagers. It’s unclear whether the decline has been in connection with a growing concern over obesity, especially among the country’s youth.
But the drop in pizza consumption, while significant hasn’t been big enough “It’s a positive trend,” Dietz said. “But we’re not quite them yet.”
It’s easy to see the appeal of pizza. It’s cheap. Parents can buy a lot of pizza for not a lot of money. Besides, they can buy pizza from a chain shop, a mom-and-pop store or a grocery freezer. And it’s universally loved. The estimated 3 billion pizza eaten each year in the United States is a proof of the food’s unmatched popularity. Given how much the country loves pizza, what’s to be done? Dietz suggests pizza with smaller serving sizes and healthier toppings(配料). “We’re not suggesting that kids avoid pizza altogether.” said Dietz. “But when parents serve it, it’s important that they understand it’s extremely caloric. They should serve smaller pizza, or at least smaller slices.”
1.According to the study, the problem with kids is that .
A. they are overweight B. they have too many takeaways
C. they are fed too much pizza D. they have very bad health
2.How did the researchers get the result?
A. Through interviewing. B. By analyzing data.
C. By tracking kids’ diets. D. Through experimenting.
3.We know from the passage that when kids eat pizza, .
A. they usually don’t eat other food B. they eat less of other food
C. they are not likely to balance their diet D. they usually eat with vegetables
4.What does the underlined part a silver lining in Paragraph 7 probably mean?
A. Something hopeful B. Something valuable.
C. Something miserable. D. Something successful.
5.What’s the key message of the last paragraph?
A. Pizza consumption fell significantly in America.
B. Pizza has many advantages over other food.
C. Eating too much pizza can lead to failing health and obesity.
D. The pizza problem may be improved through its size and topping.

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'.
